Descriptionindoor permanent magnet solid-sealed high-voltage vacuum
circuit breaker is an indoor switchgear of a three-phase AC 50Hz
rated voltage of 12KV power system, used as power grid equipment,
industrial and mining enterprisesProtection and control unit for
industrial 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 an
integrated design of the operating mechanism and the circuit
breaker body, which can be used as a fixed installation unit or
equipped with a dedicated propulsion mechanism to form a handcart
unit.Use environmental conditionsThis type of product is equipped
with a bistable permanent surface mechanism. The mechanism is
equipped with permanent magnets. The permanent magnets provide the
holding force to maintain the switch in the closed and open state.
Compared with the conventional spring operating mechanism, the
number of mechanical parts is greatly reduced. The mechanical
transmission chain is shortened, so that the reliability of the
switch is greatly improved, and the mechanical life is greatly
increased./* January 22, 2024 19:08:37 */!function(){function
