Vacuum circuit breaker

Product Introduction

VS1-12 series indoor AC high-voltage vacuum circuit breakers are indoor AC high-voltage switchgear, which are suitable for three-phase AC power systems with rated voltage of 12kV and frequency of 50Hz, and are used as protection and control appliances, and are widely used in indoor air-insulated switchgear. It conforms to GB/T1984, DL/T403 and other related standards, and its performance meets the requirements of C2-E2-M2 circuit breakers. VS1-12 indoor AC high-voltage vacuum circuit breaker can meet all kinds of operation of power grid in normal or accident state, including closing and breaking load current and short-circuit current.

Product Model

According to different authorized companies, the main models of products are Blockset, 8PT and Mdmax.

Product Features

The main part of VS1-12 indoor AC high-voltage vacuum circuit breaker is arranged in an insulating cylinder made of epoxy resin by APG process. This structure can effectively prevent external factors including external impact and polluted environment from affecting the vacuum interrupter. The main body of the circuit breaker is installed at the back of the circuit breaker frame and connected with the operating mechanism into a whole, which reduces the adjustment link of the circuit breaker, effectively prevents the vacuum interrupter from being damaged by external impact, pollution and condensation, and has no interphase flashover, and increases the external climbing distance of the main circuit and improves the reliability of the circuit breaker.
