High Voltage Capacitor Bank 50Hz,
High Voltage Capacitor Bank DL/T 840—2003
The filter capacitor is composed of a pack, a case, outlet porcelain busing, etc. The two sides of stainless steel case are welded with hanging brackets for installation, and one hanging bracket is equipped with a grounding bolt. In order to adapt to various voltages, the pack is composed of several small elements connected in parallel and series. The capacitor is equipped with a discharge resistor.
The high-voltage filter capacitor is connected with other components to form an AC filter, which is connected in parallel in a 50Hz or 60Hz high-voltage AC power system to provide a low-impedance channel for one or more harmonic currents and reduce the harmonic level of the network , Improve the power factor of the system.

3.1 Casing: Cold-pressed, anti-fouling type casing is adopted, and the creepage distance is not less than 31mm/kV.
3.2 Mature internal fuse technology.
3.3 Liquid medium: 100% benzyltoluene (M/DBT) is used. This liquid has excellent low temperature performance and partial discharge performance.
3.4 The main insulation adopts a composite insulation structure, which not only guarantees excellent electrical performance, but also has a certain degree of mechanical strength, which ensures that the insulation of the capacitor complete set of devices is 100% reliable without protection.
3.5 Good sealing performance: The annual leakage rate is less than 0.1%, and the sealing performance of the capacitor is guaranteed through measures such as automatic argon arc welding, vacuum leak testing, and thermal aging.
3.6 Partial discharge level: the extinguishing voltage is not less than 1.5Un, and each capacitor is tested for partial discharge during the factory test.
