Description
The endnote numbers is composed of three uppercase Chinese phonetic alphabets, each letter represents mainline mode (A: single star line, B: double star line), the second letter indicates protection mode of the capacitor bank (L: unbalanced current protection, K: open triangle voltage protection), the third letter refers to the occasion of use. W represents outdoor occasion, blank means indoor occasion.
Executive standards: JB7111-93 High-voltage shunt capacitor device, GB50227-95 Code for design of installation of shunt capacitors.
The device takes parallel capacitor as the main body; it is also equipped with current transformer, fuse, lightning arrester, series reactors and so on. The body of switchgear uses high-quality cold-rolled steel with ventilation shutters panels. The entire device has small volume, compact structure and reasonable layout.
Working conditions:
- Altitude of the installation site should not exceed 1000m;
- Ambient temperature of the installation site should be within -25℃~+40℃ (indoor), -40℃~40℃ (outdoor);
- Installation site should be free of violent mechanical vibration, no poisonous or harmful gas or steam, far away from conductive or explosive dust.
Product Features:
- The capacitor bank adopts grouped switching, which has high utilization of capacitors.
- It is optional for manual switching, or automatically switching with reactive power controller.
- The switching device has a perfect “five- preventions”, with simple and clear operation procedures.
- It can be connected through the communication interface to the integrated automation system to meet the operation and management requirements of the unattended and centralized control of the substation.
- It has over temperature and over voltage protection, with internal and external fault locking function.
