Product description

1. Product use

Dry-type air-core series reactors are suitable for 6, 10, and 35kV power systems. They are connected in series with shunt capacitors to suppress the distortion of the grid voltage waveform, thereby changing the quality of the grid and ensuring the safe operation of the power system; suppressing the harmonics flowing through the capacitor bank Current and limit the closing inrush current to protect the capacitor and make it operate safely and reliably.

 

2. Use environmental conditions

1. Place of use: outdoors or indoors, indoor use should pay attention to ventilation and heat dissipation.
2. Ambient temperature: -40~45℃.
3. Relative humidity: the monthly average does not exceed 90%, and the daily average does not exceed 95%.
4. Maximum wind speed: no more than 30m/s.
5. Altitude: no more than 1000m (please specify when ordering).
6. Earthquake resistance: it can withstand an earthquake with an intensity of 8 degrees.
7. There should be no severe vibration or turbulence in the installation and operation area.
8. The installation and operation area should be free of harmful gas, steam, conductive or explosive dust.
(If there are special requirements, please indicate when ordering.)

 

3. Implementation standards

1. GB/T1094.6-2011 "Power Transformer Part 6: Reactor"
2. JB5346-2014 "Series Reactor for High Voltage Shunt Capacitors"
3. IEC280-1987 "Reactor Standard"
4. DL462-92 "Technical Conditions for Ordering Series Reactor for High Voltage Shunt Capacitors"

 

4. Product structure

1. The reactor adopts a dry hollow structure to avoid oil leakage, flammability and other shortcomings of oil-immersed reactors, simple maintenance, safe operation, no iron core, no ferromagnetic saturation, and the inductance value will not change with current changes. Good linearity and low noise.
2. The reactor is encapsulated by the non-lattice glass ribbon impregnated with epoxy resin, and the reactor coil adopts polyester film and glass filament with excellent insulation performance as the inter-turn insulation of the wire.
3. The surface of the reactor is covered with ultraviolet radiation-resistant silicone organic paint, which has good resistance to outdoor weather conditions.
4. The reactor uses polyester glass pull rod as the axial heat dissipation air passage, which has good heat dissipation performance.
5. When calculating the temperature rise of the reactor, the maximum temperature of the hot spot is considered, and a considerable margin is left, thereby ensuring the long-term safe operation of the reactor.
6. Since the reactor adopts a multi-layer parallel structure, the axial electrical stress of the coil is zero, and the voltage distribution along the axial height of the coil is uniform under the steady-state operating voltage.
7. Since the reactor is encapsulated with a non-lattice glass ribbon impregnated with epoxy resin, the coil has good integrity after curing, and the noise level of the reactor during the entire service life is less than 60dB.
8. The reactor uses aluminum wires with a small cross-section (Φ1.5~Φ5) as the coil wires, which effectively reduces the eddy current loss in the wires under harmonic conditions.
9. Since the reactor uses epoxy resin-impregnated glass ribbon to encapsulate the coil, the huge mechanical force generated when the reactor passes the short-circuit current is borne by the encapsulation, so that the entire coil has extremely high resistance to short circuits Current capability.
10. The conductive parts of the reactor are all welded by argon arc welding, and there are no fastening parts on the mechanical structure, which greatly improves the operational reliability.
11. The entire reactor has a simple and compact structure and can operate in outdoor weather conditions for a long time, without equipment maintenance requirements.

8. Hoisting transportation and unpacking acceptance

1. This product has packaging suitable for long-distance transportation. Avoid falling, serious collisions, bumps, etc. in transportation, loading and unloading and hoisting occasions to avoid product damage.
2. The product should use lifting rings (provided by the user). When lifting, install the rings on the upper star frame and tighten the lock nuts before lifting. The lifting tools are only for lifting and the product is put into operation Must be removed before, so as not to cause local overheating.
3. Before unpacking, check the packing box for damage caused by falling, severe collision, severe vibration, or bumping.
4. After unpacking, first check whether the nameplate data of the reactor is complete.
5. Check whether all parts are complete according to the packing list.
6. Check whether the technical documents attached to the product are complete according to the packing list.
7. Check the appearance of the reactor, components and accessories for serious defects or damage caused by serious collisions.
8. The exterior of the reactor is coated with outdoor anti-ultraviolet paint. The paint layer around should be carefully checked for peeling caused by scratches.
9. The purchaser can carry out the following acceptance test items when conditions permit:
a. Winding resistance measurement;
b. Power frequency withstand voltage test, the test voltage value shall be 75% of the factory test value or a lower voltage.

 

9. Installation (see attached drawings 1, 2, 3 for basic installation form and installation dimensions)

1. Requirements for the installation site
a. The safety distance between the reactor and its surrounding metal parts should consider both the electrical safety distance and the alternating magnetic field safety distance. The maximum value between the two should be taken. The electrical safety distance shall be determined in accordance with relevant regulations.
b. There should be no thick metal components within a distance of 1.1 times the reactor diameter from the center of the reactor and 0.5D from the upper and lower star frame end faces. For large metal parts and metal parts forming a closed loop, the distance should be increased. There should be no steel bars and other metal components forming a closed loop in the foundation under the reactor chassis.
c. When several products need to be installed together, the net distance of each product must consider the electrical safety distance and the alternating magnetic field safety distance, and take the larger one. In order to prevent the alternating magnetic field of the two products from having a great influence (mutual inductance) and causing serious changes to the parameters of the reactor, there should be at least 1.7 times the net distance between the centers of the two reactors.
d. If the reactor is installed outdoors or in a spacious workshop, no special ventilation equipment is required. For reactors installed in a closed cell, in order to ensure the heat dissipation conditions, the cell should be equipped with a ventilation device.
2. Installation precautions
a. There are two installation methods for dry-type air-core reactors: stacking and splitting. The installation must be carried out in strict accordance with the specified installation method, that is, split-packing products cannot be installed into stacking or stacking products by themselves. Disassemble and install the components into one assembly type, so as not to change the reactor parameters and cause the reactor to fail to meet the requirements or burn out. For stacked reactors, the bottom-up installation sequence should strictly follow the requirements of the installation steps and cannot be reversed arbitrarily.
b. When the reactor is impacted by a short-circuit current, it may vibrate or slightly swing. This is a normal phenomenon. Therefore, the outgoing terminal of the reactor and the external connection must be completely rigid. It is better to use a cable if possible. When a hard bus bar must be used, the bus bar should also form a buffered transition elbow.
c. The connecting bolts between the reactor and the supporting porcelain bottle are made of non-magnetic materials, and stainless steel bolts, nuts, and washers are provided as a set when the product leaves the factory.
3. Installation steps of three-phase stacked reactor
a. Use fastening bolts to install the channel steel base under the porcelain bottle on the ground pillar;
b. Use stainless steel screws to install the C-phase reactor coil on the porcelain bottle on the ground support of the channel steel base, padded and fasten it with a rubber pad (if the gap between the coil and the porcelain bottle is too large, you can use a rubber pad to adjust) ;
c. According to the installation position and the direction of the incoming and outgoing wires, place the C-phase coil with the ground pillar porcelain bottle on the embedded steel plate of the reactor foundation and weld it firmly;
d. Install rubber pads, interphase pillar porcelain bottles, rubber pads, and phase B coils upwards in turn, and tighten them (if the gap between the coil and the porcelain bottle is too large, you can use a rubber pad to adjust it);
e. Install the rubber pad, the interphase pillar porcelain bottle, the rubber pad, and the phase A coil upwards in turn, and tighten them (if the gap between the coil and the porcelain bottle is too large, you can use a rubber pad to adjust it);
f. After the reactor coil is installed, check whether the fasteners are connected reliably and whether the terminal positions of the incoming and outgoing wires are correct.
4. Installation steps of three-phase horizontally arranged reactor
a. Use fastening bolts to install the channel steel base under the porcelain bottle on the ground pillar;
b. Use stainless steel screws to install the A, B, and C phase reactor coils on the porcelain bottle on the ground support pillar with the channel steel base, add a rubber gasket in the middle and tighten it (if the gap between the coil and the porcelain bottle is too large, you can use a pad Rubber pad to adjust);
c. Place the A, B, and C phase coils of the porcelain bottle with the ground support pillars respectively on the embedded steel plate of the reactor foundation and weld them firmly according to the installation position and the direction of the wires;
f. After the reactor coil is installed, check whether the fasteners are connected reliably and whether the terminal positions of the incoming and outgoing wires are correct.
5. Installation steps of reactor with two-phase stacking and one-phase horizontal arrangement
a. Use fastening bolts to install the channel steel base under the porcelain bottle on the ground pillar;
b. Use stainless steel screws to install the phase A and phase C reactor coils on the porcelain bottle on the ground support pillar with the channel steel base, add a rubber pad in the middle and tighten it (if the gap between the coil and the porcelain bottle is too large, you can use a rubber pad To adjust);
c. According to the installation position and the direction of the incoming and outgoing wires, the A and C phase coils that have been installed with the ground pillar porcelain bottle are respectively placed on the embedded steel plate of the respective reactor foundation and welded firmly;
e. Install rubber pads, interphase pillar porcelain bottles, rubber pads, and B-phase coils on the C-phase reactor coil upwards in turn, and tighten them (if the gap between the coil and the porcelain bottle is too large, a rubber pad can be added to adjust);
f. After the reactor coil is installed, check whether the fasteners are connected reliably and whether the terminal positions of the incoming and outgoing wires are correct.

 

10. Operation and maintenance

1. Before the reactor is put into operation, check the cooling air passages to ensure that the cooling air passages are unobstructed. If foreign objects are found to block the air passages, they should be removed in time. For reactors that are only put into operation under specific conditions, Usually it is not operating, so you must always pay attention to foreign objects blocking the airway and remove it in time.
2. Frequent inspections should be made during the operation of the reactor, and records should be kept. If sags are found in the reactor, immediately exit operation to prevent accidents and notify the company's sales department.
3. The ambient temperature when the reactor is put into operation should not be lower than the allowable lower limit temperature. When the ambient temperature during operation exceeds the allowable upper limit temperature, the operation should be stopped.
