Product Introduction
Product name: VS1-12 permanent magnet indoor solid-sealed high voltage vacuum circuit breaker
Category: high voltage components
Product introduction: VS1-12 type household permanent magnet internal solid-sealed high-voltage vacuum circuit breaker is an indoor switchgear with a three-product phase AC 50Hz rated voltage of 12KV power system. It is used as a protection and control unit for power grid equipment and industrial and mining enterprise power equipment. It is suitable for places requiring frequent operation under rated working current, or multiple interruption of short-circuit current.
The main purpose of VS1-12 permanent magnet indoor solid-sealed high voltage vacuum circuit breaker
VS1-12 type household permanent magnet internal solid-sealed high-voltage vacuum circuit breaker is an indoor switchgear with a three-phase AC 50Hz rated voltage of 12KV power system, as a protection and control unit for power grid equipment and industrial and mining enterprise power equipment. It is suitable for places requiring frequent operation under rated working current, or multiple interruption of short-circuit current.
The circuit breaker adopts the one-stop design of the operating mechanism and the circuit breaker body, which can be used as a fixed installation unit, or can be equipped with a dedicated propulsion mechanism to form a handcart unit.
Performance advantages of VS1-12 permanent magnet indoor solid-sealed high voltage vacuum circuit breaker
This type of product is equipped with a bistable permanent magnet operating mechanism. The mechanism is equipped with a permanent magnet. The permanent magnet provides the holding force to keep the switch in the closed and open state. Compared with the conventional spring operating mechanism, it has a large number of mechanical parts. Reduce and shorten the mechanical transmission chain, so that the reliability of the switch is greatly improved, and the mechanical life is greatly increased.
