Problems solved by technology

With the load isolating switch of this structure, the operator cannot directly observe the actual working state of the contacts. When the load isolating switch fails, for example, it is displayed as open, but the actual state is still closed, the operator does not know. This brings certain dangers to workers during equipment and line maintenance, and the safety is poor.

Abstract

The invention relates to a novel dual-power-source automatic change-over switch which comprises a switch body. A controller is arranged in the middle of the switch body. A frequently-used power circuit breaker and a standby power circuit breaker are arranged on the left side and the right side of the controller respectively. The controller is provided with a manual / automatic change-over button and further provided with an insulation rotating handle. The insulation rotating handle can be connected with the frequently-used power circuit breaker or the standby power circuit breaker. Grounding screws and auxiliary terminals are arranged at the lower portion of the controller. The novel dual-power-source automatic change-over switch is simple in structure, convenient to operate, capable of guaranteeing stable load power supply and safe in use.

Description

technical field [0001] The invention relates to a transfer switch, in particular to a novel dual-power automatic transfer switch. Background technique [0002] The existing transfer switch is generally composed of a base, a cover, a moving contact, a static contact, an operating mechanism, and a handle. "Close" sign to indicate whether the switch is in the open state or in the closed state. With the load isolating switch of this structure, the operator cannot directly observe the actual working state of the contacts. When the load isolating switch fails, for example, it is displayed as open, but the actual state is still closed, the operator does not know. This brings certain danger to the workman when equipment and circuit maintenance, poor security. Contents of the invention [0003] In order to solve the above problems, the present invention provides a novel dual-power automatic transfer switch with simple structure, convenient operation, stable load power supply and ...
