Abstract

The invention relates to the technical field of operating mechanisms, and provides an oil pump assembly testing device of the operation mechanisms. The oil pump assembly testing device of the operation mechanisms can solve the problem that cost used for testing an oil pump assembly is high in the prior art. The oil pump assembly testing device of the operation mechanisms comprises a main operation cylinder body, an oil tank and an energy storage device, wherein a high pressure oil cavity communicating with the energy storage device is arranged in the main operation cylinder body, a low pressure oil cavity communicating with the oil tank is further arranged in the main operation cylinder body, an oil pump assembly oil outlet communicating with the high pressure oil cavity and an oil pump assembly oil inlet communicating with the low pressure oil cavity are formed in the main operation cylinder body, a test oil inlet and a test oil outlet are further formed in the main operation cylinder body, the test oil inlet is connected with the low pressure oil cavity, the test oil outlet is connected with the high pressure oil cavity, and a control valve which can achieve connection and disconnection for the test oil inlet and the test oil outlet is further arranged between the test oil inlet and the test oil outlet. The oil pump assembly testing device of the operation mechanisms further comprises an oil pump control module used for detecting pressure of the high pressure oil cavity so as to control the oil pump assembly connected onto the oil pump assembly oil outlet and the oil pump assembly oil inlet to start and stop.

Description

technical field [0001] The invention relates to the technical field of an operating mechanism, in particular to an oil pump component testing device for an operating mechanism. Background technique [0002] The high-voltage circuit breaker is the key equipment for power transmission, and the operating mechanism is the key component of the high-voltage circuit breaker. The function of the operating mechanism is to close the circuit breaker and maintain it in the closed state and the open state. The operating mechanism of the circuit breaker is mainly divided into hydraulic spring operating mechanism, electromagnetic operating mechanism, pneumatic operating mechanism, etc., and the disc spring hydraulic operating mechanism is one of the hydraulic spring operating mechanisms. Disc springs are widely used for energy storage because of their compact structure and stable mechanical operation characteristics. [0003] The disc spring type hydraulic operating mechanism in the prior...
