1 Overview
A device consisting of a high-voltage shunt capacitor, a capacitor cabinet or metal frame, a fuse, a discharge device, a series reactor, a pillar insulator, a lightning arrester, a disconnecting switch, a grounding switch, a circuit breaker and a connecting bus, is called a high-voltage shunt capacitor device (hereinafter referred to as the "device"). Its performance conforms to the standards of GB/T 30841-2014 "General Technical Requirements for High Voltage Shunt Capacitor Devices" and GB50227-2017 "Design Specification for High Voltage Shunt Capacitor Devices".
2 Uses
It is mainly used for reactive power compensation in 6kV, 10kV and 35kV power frequency power systems to improve power factor of the grid, reduce line losses and improve voltage quality.
3 Features
3.1 Safe and reliable.
3.2 Easy Installation.
3.3 Easy maintenance.
3.4 Strong integrity.
4 Technical Data
4.1 Main Parameters
4.1.1 High voltage shunt capacitor devices are arranged in various ways. This design and selection manual only lists typical layout schemes. The main parameters and dimensions of the device are shown in Appendix A and Appendix B of the table, and the main wiring modes are shown in Appendix C of the figure for users' reference.
4.1.2 Rated frequency of device: 50Hz
4.1.3 Number of device phases: 3 phases
4.2 Main Performance
4.2.1 Loss Angle tangent value of capacitor in the device: full film medium structure, no more than 0.0005.
4.2.2 Capacitance deviation of the device: The deviation between the measured capacitance of the capacitor bank in the device and its rating shall not exceed 0 ~ +5%. The ratio between the maximum value and the minimum value of any two-phase measured capacitance of the capacitor bank is not greater than 1.02; The ratio between the maximum and minimum measured capacitance of each series segment is no more than 1.02.
4.2.3 The device is allowed to operate for a long time at 1.1 times the rated voltage.
4.2.4 The device is allowed to operate for a long time under steady overcurrent with an effective value of 1.3 times the rated current due to overvoltage and higher harmonics.
5 Structure
5.1 The device installed indoors is cabinet structure or section steel frame structure, and the device used outdoors is section steel frame structure.
5.2 Cabinet structure is generally composed of wire inlet cabinet, transformer cabinet, capacitor cabinet and reactor cabinet. The cabinet body is made of high quality cold rolled steel plate and aluminum zinc steel plate, which is processed by advanced CNC machine tool. The surface is treated by pickling phosphating spray technology, and the cabinet body is beautiful.
5.3 Medium and high voltage shelled capacitors in the device are diarylethane impregnated polypropylene film or benzyltoluene impregnated polypropylene film. The rated capacity of a single capacitor is 100kvar, 200kvar, 334kvar, 500kvar, etc
5.4 When the rated capacity of a single capacitor in the device is less than 200kvar, the external fuse is used as the first level of protection for internal faults; when the rated capacity of a single capacitor is more than 200kvar, the internal fuse is generally used as the first level of protection for internal faults.
The external fuse is connected with the capacitor in series. When there is a partial series breakdown inside a capacitor, the fuse will act to remove the faulty capacitor quickly and effectively prevent the expansion of the fault.
The internal fuse is connected in series with the internal components of a single capacitor. Once the component fails, the fuse is blown and the faulty component is removed, allowing the remaining parts of the single capacitor and the capacitor bank connected to the capacitor to continue to operate.
5.5 The discharge coil is connected in parallel in the capacitor loop. After the capacitor is removed from the grid, the remaining voltage on the capacitor can be reduced from √2Un to 50V or lower within 5s.
5.6 The zinc oxide arrester is connected in parallel to the wire to limit the operating overvoltage caused by switching capacitor banks.
5.7 Series reactor connected in series in the capacitor loop can be placed before or after, to restrain the higher harmonics in the capacitor bank and limit the closing inrush current. When it is only used to limit inrush current, the reactance is selected from 0.1% to 1%. When it is used to suppress 5 or more high harmonics, the reactance rate is 5% ~ 6%. When it is used to suppress 3 or more high harmonics, the reactance rate is 12%.
