Anti-overvoltage device of high-voltage circuit breaker

Abstract

The invention discloses an anti-overvoltage device of a high-voltage circuit breaker. The device comprises a machine body, an operation cavity is formed in the machine body, an insulation protection layer penetrating through the machine body left and right is fixedly arranged in the machine body, a voltage measuring mechanism is arranged in the operation cavity, a warning cavity with an upward opening is formed in the upper end face of the machine body, and a warning mechanism is arranged in the warning cavity. A power cavity is formed in the right side of the right inner wall of the operationcavity, a power mechanism is arranged in the power cavity, and the voltage measuring mechanism comprises a brake cavity which is located in the lower inner wall of the operation cavity and provided with a downward opening, the structure is simple, operation is convenient and fast, and when the voltage is too high, automatic detection and cut-off protection can be completed through mechanical transmission. After the cable is cut off, warning can be automatically sent out through mechanical transmission, and when maintenance is completed, warning can be automatically withdrawn and reset throughmechanical transmission, so that the workload of workers is reduced.

Description

technical field [0001] The invention relates to the related field of circuit breakers, in particular to an overvoltage prevention device of a high-voltage circuit breaker. Background technique [0002] In the process of power transmission, cables are needed for power transmission. When the voltage is too high, there will be great danger. The cable needs to be cut off for protection. When the voltage is too high, a warning needs to be issued. [0003] At this stage, the cut-off protection and warning are manually operated when the voltage is too high. Not only is there a cumbersome process of cutting off the protection and issuing a warning when the voltage is too high, but it also consumes a lot of physical strength of the workers and increases the worker's workload. workload. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide an overvoltage prevention device for a high-voltage circuit breaker, which overcomes the ...
