The invention discloses a relay state comprehensive on-line monitoring and fault diagnosis device. The device comprises a conveying belt, an on-line fault diagnosis table and a transfer assembly, wherein the on-line fault diagnosis table comprises a test platform, a fault detection line and a processing system; the fault detection circuit is composed of a power end, a load end, a segmented circuit, a current measuring instrument and a gravity sensing plate used for being installed on the segmented circuit, and the processing system achieves fault diagnosis of the relay according to output data of the current measuring instrument; limiting clamping plates are arranged at two ends of the gravity sensing plate on a lower surface of the testing platform, the limiting clamping plates limit the vertical linear movement of the gravity sensing plate, the gravity sensing plate is flush with the testing platform in a non-load state and is connected and conducted through a segmented circuit, the gravity sensing plate moves downwards under the action of external force in a load state, and the segmented circuit is connected and conducted through a relay; and the processing system carries out fault detection and diagnosis by comparing output data of the current measuring instrument, and the method is simple in implementation mode and high in fault diagnosis efficiency.
Description
technical field [0001] The invention relates to the technical field of relay fault detection, in particular to a relay state comprehensive on-line monitoring and fault diagnosis device. Background technique [0002] As we all know, the relay is an electrical control device, which is an electrical appliance that causes the controlled quantity to undergo a predetermined step change in the electrical output circuit when the change of the input quantity excitation quantity meets the specified requirements. It has an interactive relationship between the control system, also known as the input loop, and the controlled system, also known as the output loop. Usually used in automatic control circuits, it is actually an "automatic switch" that uses a small current to control the operation of a large current. Therefore, it plays the role of automatic adjustment, safety protection, conversion circuit, etc. in the circuit. This embodiment mainly tests the safety protection function of ...
