Sichuan specialty store of permanent magnet high-voltage 35KV outdoor vacuum circuit breaker

Vacuum circuit breakers mainly consist of three parts:

Vacuum arc extinguishing chamber, electromagnetic or spring operated mechanism, bracket and other components
The intelligent vacuum integrated prepaid device is a replacement product for the separate structure of vacuum switch and high-voltage metering box. This product combines the metering CT and PT into one, with a fully enclosed structure, suitable for the rainy and foggy climate in the south.

Small in size and easy to install in weight, with no exposed interface for the secondary leads of the switch and metering parts, the overall anti-theft capability is improved. Single pole installation reduces the significant cost of hardware and scaffolding during dual pole installation. The remote prepaid control part effectively solves the long-standing problem of high line loss caused by electricity theft and arrears in the power industry, achieving intelligent, information-based, and automated management of end users in the power industry.

The intelligent high-voltage vacuum circuit breaker with GPRS communication function realizes the intelligent and remote measurement and control of high-voltage lines, and blocks all means of stealing electricity, which is an inevitable choice for the construction of modern smart grids.
