The invention discloses a comprehensive on-line monitoring and fault diagnosis device for relay status, which includes a conveyor belt, an online fault diagnosis platform and a transfer assembly. The online fault diagnosis platform includes a test platform, a fault detection circuit and a processing system. The fault detection circuit consists of a power supply terminal, The load terminal, segment circuit, current measuring instrument and gravity sensing board used to install the segment circuit, the processing system realizes the fault diagnosis of the relay according to the output data of the current measuring instrument; the lower surface of the test platform is on the two sides of the gravity sensing board There is a limit card plate at the end, and the limit card plate restricts the linear movement of the gravity sensing board up and down. When the gravity sensing board is in the no-load state, it is flush with the test platform and the segmented circuit is connected to conduct electricity. When the gravity sensing board is under load, it is under the action of an external force. shift, and the segmented circuit is connected to conduct electricity through the relay, and the processing system performs fault detection and diagnosis by comparing the output data of the current measuring instrument. The implementation method of the present invention is simple, and the fault diagnosis efficiency is high.
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 ...
