Testing device of electromagnetic tripping device

Abstract

The invention discloses a testing device of an electromagnetic tripping device. The testing device comprises a testing substrate; the positioning mechanism is arranged on the test substrate and is used for fixing the shell of the electromagnetic tripping device; the pushing and pressing part is used for abutting against the ejector rod; the connecting part is connected with the pushing and pressing part, and the connecting part and the pushing and pressing part can synchronously move forwards or backwards relative to the test substrate; the driving mechanism is used for driving the pushing and pressing part to move in the forward direction so that the ejector rod can be in a retracted state; the interface is electrically connected with an upper computer; the switch is electrically connected with the interface, the switch is provided with a mechanical triggering part, the mechanical triggering part abuts against the connecting part, the mechanical triggering part is used for being pressed after the pushing and pressing part moves reversely to enable the switch to be switched on, and the switch sends a test signal to the upper computer through the interface; and the wire clamping device is electrically connected with the interface and is used for supplying power to the electromagnetic tripping device, so that the ejector rod is switched from the retraction state to the extension state and drives the pushing and pressing part to move reversely. The service life and the stability of the testing device can be improved.
