Spring operating mechanism detection device

Abstract

The invention discloses a spring operating mechanism detection device comprising a test support. One end of the test support is provided with an arc-extinguishing component via an arc-extinguishing chamber fixing rod box. The other end of the test support is provided with a tested spring operating mechanism. The arc-extinguishing component and the tested spring operating mechanism are connected via a connecting mechanism. The test support is also provided with a test mechanism used for detecting the tested spring operating mechanism. The spring operating mechanism to be detected and the arc-extinguishing component of a circuit breaker are matched through circuit connection so that simulation of the real use state of the high-voltage circuit breaker can be realized, one-to-one detection can be realized, the overall product performance of the finished high-voltage circuit breaker can be fully guaranteed, yield rate of the product can be enhanced and repair rate and quality accidents of the product can be reduced.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a device for monitoring the state of its components during the production of high-voltage circuit breakers. Background technique [0002] During the operation of the power system, in order to ensure the safety of the power system, it is necessary to put some or all of the electrical equipment and some or all of the lines into or out of operation. Cut off or close the no-load current and load current in the high-voltage circuit, and cut off the overload current and short-circuit current through the function of the relay protection device when the system fails. It has a fairly complete arc-extinguishing structure and sufficient current-breaking capacity. The spring operating mechanism is a part of the high-voltage circuit breaker. It uses the energy stored in the stretching and contraction of the spring to perform closing and opening operations. The spring energy stora...

Problems solved by technology

However, relying solely on the qualified inspection results of the manufacturer of the spring operating mechanism, it is impossible to test the matching of the spring operating mechanism and the arc-extinguishing parts of the unit's circuit breaker, and it is also impossible to truly test the use effect of the combination of the spring operating mechanism and the circuit breaker; If the high-voltage circuit breaker is assembled and then tested, the overall performance of the high-voltage circuit breaker, the matching and operational performance of the high-voltage circuit breaker and the power grid are tested at this time, and it is impossible to independently extinguish the arc of the spring operating mechanism and the circuit breaker.
