Operating mechanism load simulation device and operating mechanism delivery test method

Abstract

The invention relates to an operating mechanism load simulation device and an operating mechanism delivery test method. The operating mechanism load simulation device comprises a rack, a magneto-rheological damper fixed relative to the rack, and a control device connected with the magneto-rheological damper. The rack is used for fixing an operating mechanism to be tested, the magneto-rheological damper is used for being in transmission connection with the operating mechanism to be tested so as to simulate the load of the operating mechanism, and the control device is used for controlling the magnitude of current introduced into the magneto-rheological damper so as to simulate the switching-on and switching-off resistance of a circuit breaker connected with the operating mechanism to be tested. The operating mechanism delivery test method comprises the steps that the magneto-rheological damper is in transmission connection with the operating mechanism to be tested, and when the operating mechanism starts to be switched on and off, the magneto-rheological damper is powered on, and the magnitude of damping force generated by the magneto-rheological damper is changed by changing the magnitude of the introduced current in real time so as to simulate the load of the operating mechanism. The operating mechanism load simulation device can accurately simulate the load of the operating mechanism.

Description

technical field [0001] The invention relates to a load simulation device for an operating mechanism and a delivery test method for the operating mechanism. Background technique [0002] The opening and closing of the circuit breaker is mainly realized by the operating mechanism, so the characteristics of the circuit breaker are also mainly determined by the operating mechanism, such as opening and closing speed, opening time and closing time. The existing operating mechanisms of circuit breakers include spring operating mechanisms, hydraulic operating mechanisms, and electromagnetic operating mechanisms. self-inflicted damage. Therefore, in order to ensure the reliability of the operating mechanism, each operating mechanism must be debugged with load and a certain number of operation tests must be carried out before leaving the factory, and the test of the operating mechanism must use the corresponding test simulation device. [0003] The existing circuit breaker operating...
