Compact HV Shunt Capacitor Bank upto 80000kvar

HV shunt capacitor bank

1. Overview

High-voltage shunt capacitor devices mainly include the following equipment: high-voltage shunt capacitors, series reactors, discharge coils, zinc oxide arresters, isolation grounding switches, frames, bus bars, connecting wires, post insulators, cabinets or fences, etc. The capacitor device switching circuit breaker and its protection device and controller can be included in the supply according to the needs of users.
High-voltage shunt capacitor devices are mainly used in power frequency three-phase AC power systems to improve system power factor, reduce transformer and line losses, improve grid voltage quality, and increase equipment utilization.

2. Classification and usage

2. 1 Classification
(1) According to the installation type, it can be divided into two types: cabinet type and frame type.
(2) According to the switching mode, it can be divided into manual switching and automatic switching.
(3) According to the conditions of use, it can be divided into indoor and outdoor types.
2.2 Function:
It is mainly used in three-phase power systems such as power frequency voltage 10kV～750kV to adjust and balance the voltage of the substation network, improve the power factor, reduce the loss, and improve the quality of power supply.

3. Main features
