Abstract

The invention discloses a connecting rod structure-based circuit protection device, which comprises a circuit breaker. The circuit breaker is sequentially in series connection with a feeder switch anda travel switch through a lead. A connecting rod device is connected between the feeder switch and the travel switch through an insulating tape. The connecting rod device comprises a base and the base is fixedly connected with a rack vertical to the base. The two sides of a machine frame are respectively and movably connected with a connecting frame rod A and a connecting frame rod B. The connecting frame rod A and the connecting frame rod B are connected through a connecting rod. According to the invention, the connecting rod device is driven by the travel switch to trigger the feeder switch, so that the feeder switch can be switched on in the no-load condition. The condition that the feeder switch is switched on in the load condition can be avoided. The feeder switch is protected. The device is simple in operation and good in usage value.

Description

technical field [0001] The invention belongs to the technical field of transformer circuit protection equipment, and in particular relates to a circuit protection device based on a connecting rod structure. Background technique [0002] The feed switch is used as a switch set in the transformer outlet cabinet to control the use of the feed of the outlet. As a feed switch, it not only protects the switching device from overload, phase failure, leakage, etc., but also must ensure that when the outlet of the feed switch is short-circuited, it can break the short-circuit current to protect the transformer and prevent the high-voltage switch at the upper end of the transformer from generating Large-scale power outage accidents caused by the operation. In use, when the feed switch is switched on, the circuit breaker in the circuit can be disconnected, but generally the feed switch is easily damaged when it is operated with a load. Contents of the invention [0003] The purpose...
