First, outlined
High Voltage Shunt Capacitor Installation, mainly for the power frequency system, the power factor to improve power grids, improve voltage quality and reduce the wear and tear of lines and equipment, improve the economic efficiency of power transmission equipment.
Second,
the performance of the device allows for 1.1 times the rated voltage and frequency of long-term operation, the operation of state, including all of the harmonic voltage peak 2Un should not be more than 1.2%. Since the device allows voltage and high-order harmonic generation in the RMS current of 1.3 times the rated current stable than under continuous operation. Rated capacitor with capacitance devices practical difference does not exceed the rated 0~+10%, any two terminals installed capacity means the maximum and minimum ratio of not more than 1.06. MOA and devices containing series reactor that can effectively restrict over-voltage operation, high harmonics and flourish. Fuse as one of the main devices used to protect single capacitor voltage differential, opening triangular voltage, current poor bridge, or neutral line voltage protection as the current imbalance relay. In addition, the device also has over-current, short circuit and white bus-speed, over-voltage, voltage protection.

Third, the implementation of standards   Shunt capacitor devices JB7111-1993   GB50227-95 shunt capacitor design standards   MPC GB/T11024.1-2001 nominal voltage power system more exchanges with the relevant standards and shunt capacitors Part 1  
Four,
Structure   Shunt capacitor to the main device, according to the user's needs, equipped with current transformer and fuse, MOA, series reactor and discharge coils and isolating switches to relay and measurement, instructions, etc., using high-quality cold-rolled steel enclosure from the elbow.   Fuse link with the series capacitors, a part of a series of internal capacitor breakdown, Fuse moves quickly removed capacitor failure to effectively prevent failures to expand.   Shunt capacitor discharge coils connected in the loop, from the power grid when the capacitor from the operation, make the remaining voltage on the capacitor within 5S dropped since ¡Ì 2Un 50V or less.   MOA parallel line connecting roads to limit switching capacitor voltage caused by the operation.   Series reactor connected in series capacitor circuits, capacitors inhibit the high-order harmonic generation, inrush current limit switch. Series reactor for the reactor only for restricted flow rate of -0.1 admission, more than five times the harmonic curbing choose 4.5%-6%, more than three times the harmonic curbing choice about 12-13% of its total supply.   Frame structure devices may also be used, according to user requirements and venues, with a corresponding alignment of the wiring and relay.
