Product Details

1 Overview
A device composed of high-voltage parallel capacitors, capacitor cabinets or metal frames, fuses, discharge devices, series reactors, pillar insulators, lightning arresters, isolating switches, grounding switches, circuit breakers and connecting busbars, is called high-voltage parallel capacitor devices (Hereinafter referred to as "device"), its performance meets 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 use
It is mainly used for reactive power compensation in 6kV, 10kV and 35kV power frequency power systems to improve the power factor of the grid, reduce line losses, and improve voltage quality.
3 features
3.1 Safe and reliable.

3.3 Easy to maintain.
3.4 Strong integrity.
4 technical data
4.1 Main parameters
4.1.1 There are various arrangements for high-voltage shunt capacitor devices. Only typical layout schemes are listed in this design and selection manual. The main parameters and dimensions of the device are shown in Table Appendix A and Figure Appendix B. The main wiring methods of the device are shown in Appendix C. , For user reference.
4.1.2 Device rated frequency: 50Hz
4.1.3 Number of device phases: 3 phases
4.2 Main performance
4.2.1 The loss tangent value of the capacitor in the device: full-film dielectric structure, not 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 rated value shall not exceed 0～+5%. The ratio of the maximum value to the minimum value of any two-phase measured capacitance of the capacitor bank is not more than 1.02; the ratio of the maximum value to the minimum value of the measured capacitance of each series section is not more than 1.02.
4.2.3 The device allows long-term operation at 1.1 times the rated voltage.
4.2.4 The device allows long-term operation under steady-state overcurrent of 1.3 times the rated current caused by overvoltage and higher harmonics.
5 structure
5.1 The device installed indoors is a cabinet structure or a steel frame structure, and the device used outdoors is a steel frame structure.
5.2 Cabinet structure generally consists of incoming line cabinet, voltage transformer cabinet, capacitor cabinet and reactor cabinet. The cabinet body is made of high-quality cold-rolled thin steel plate and aluminum-zinc steel plate, which are processed and formed by advanced CNC machine tools. The surface is treated with acid washing and phosphate spraying process, and the cabinet body is beautiful.
5.3 The dielectric structure of the high-voltage shunt capacitor in the device is diarylethane impregnated all polypropylene film or benzyl toluene impregnated all polypropylene film type. 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 its internal failure. When the rated capacity of a single capacitor is ≥200kvar, the internal fuse is generally used as the first level of protection for its internal failure.
The external fuse is connected in series with the capacitor. When a part of the series section inside a certain capacitor breaks down, the fuse will act to quickly remove the faulty capacitor, effectively preventing 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 will blow and the faulty component will be cut off, allowing the rest 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 circuit. When the capacitor is withdrawn 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 on the line to limit the operating overvoltage caused by switching the capacitor bank.
5.7 Series reactors connected in series in the capacitor circuit can be pre- or post-installed to suppress the higher harmonics in the capacitor bank and limit the closing inrush current. When only used to limit inrush current, select the reactance rate from 0.1% to 1%; when used to suppress the 5th and above harmonics, select the reactance rate from 5% to 6%; when used to suppress the 3rd and higher harmonics , The reactance rate is 12%.
