Details

1. Product use

The capacitors described in this manual are intended for indoor capacitor units and banks specially designed to improve the power factor or loop characteristics of induction heating, melting, stirring or casting installations and similar applications in controlled or adjustable AC voltage systems with nominal voltages not greater than 4kV and frequencies of 50kHz and below.

2. Product model and meaning

3. Product structure

3.1 The capacitor is mainly composed of shell, wiring guide bar and heart.

3.2 The shell is made of aluminum plate bent and welded, and it is equipped with capacitor heart, which is full of insulating oil with excellent electrical performance. The two ends of the shell are welded with brackets for installation and hoisting, and the shell cover is equipped with wiring guide rods sealed with silicone rubber and supported by porcelain bushing.

3.3 Capacitor core consists of several components, which are stacked into a whole through insulation gasket, splints, etc., in accordance with the design regulations. The cooling water pipe is directly welded into a whole with the component plate.

4. Conditions of use

4.1 The elevation of the installation site shall not exceed 1000m.

4.2 Indoor air temperature ranges from -40 ℃ to +45℃.

4.3 The remaining voltage at re-energizing shall not exceed 10% of the rated voltage.

4.4 Inlet pressure of cooling water shall not exceed 0.4Mpa, inlet water temperature shall not exceed 30℃, flow rate of cooling water shall not be less than 6L/min, cooling water shall be soft water without impurities, PH value shall be 6 ~ 9.

5. Main technical performance and data

5.1 Product Standards

Part I General for power capacitors for induction heating installations (equivalent to Part I general for power capacitors for induction heating installations IEC60110.1).

5.2 Capacitor terminals (electrode) can withstand 2.0UN power frequency test voltage for 10s.

5.3 For capacitors whose terminals are all insulated from the housing, the power frequency test voltage between the terminals and the housing shall be 2.15UN and at least 2000V for 10s.

5.4 Capacitance deviation range: no more than -5% ~ +10% of the rated value.

5.5 At rated power frequency voltage, the tangent value of capacitor loss Angle (tgδ) should not be greater than 0.0008

5.6 Overload: The capacitor can run continuously at rated voltage and 1.15 times rated current, and can run for no more than 12 hours every 24 hours at 1.05 times rated voltage.
