Abstract

The invention discloses a reactive compensation system. The reactive compensation system includes a switch, lightning arresters, a voltage transformer and a plurality of groups of combination capacitors, wherein the switch, the lightning arresters, the voltage transformer and the combination capacitors are fixed on a wire pole through a support; a current transformer is arranged on a three-phase transmission line and is connected with the combination capacitors; the plurality of groups of combination capacitors are in parallel connection, and three phases of each group of combination capacitorare respectively connected with the three phase output terminal of the switch; the three phase input terminal of the switch is connected with the three-phase transmission line; the three lightning arresters are respectively arranged on the three phase connecting line between the switch and the combination capacitors; the voltage transformer is connected with the three phase input terminal of thecombination capacitors respectively; and each combination capacitor includes a drive device, an intelligent assembly, a hurl-slices switch, a housing and a capacitor. The reactive compensation systemis small in volume, is modularized, and is convenient for installation.

Description

technical field [0001] The invention relates to a compensation device, in particular to a reactive power compensation system. Background technique [0002] The general practice of the existing reactive power compensation device is to add a reactive power compensation box containing power capacitors, controllers, switching switches, etc. and a current transformer for measuring current on the line. There are many components in the box and most of them are not rainproof, so an external box must be added to protect these components. The cabinet design is generally based on non-standard customization. Once formed, the configuration cannot be changed, and there is little room for expansion. Therefore, the current reactive power compensation device has the following disadvantages. 1. There are many components, large volume and complexity, which is not easy to install and maintain. 2. With the addition of a box, the economy is poor. 3. Configurable, scalable, high maintenance an...
