How to improve the reliability of relay 24v operation?

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 in the input quantity meets the specified requirements. It has an interactive relationship between the control system and the controlled system. Usually used in automated 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, and conversion circuit in the circuit.

The reliability of relay operation is an important parameter of relay 24v. Relay 24v is a component with control function and relay protection. How to improve the working performance of relay 24v?

First, when the protection setting value or the second circuit changes, check the setting value or protection circuit with related precautions, and record the content, time, modification leader, and operation team leader’s signature in the change book. on. The modification of the main protection equipment also requires commissioning or commissioning tests. For example, if the differential protection is replaced with a CT, it must pass the hexagonal test before it can be put into use.

Second, pay attention to the acceptance of the relay protection. After the relay protection is debugged, strictly self-inspect and professionally accept, and then submit the wiring list. The three departments of the factory will organize maintenance, operation, and production to conduct the entire set of protection tests and switches. After passing the jump test, confirm that the stitches, components, signs, pressure plates, etc. have returned to normal. After the site is civilized, sanitary and clean, sign the acceptance form.

Third, in addition to the shift inspection, the whole class arranges a more detailed inspection.

Fourth, strict inspections and inspections of the relay 24v protection device and its secondary circuits are important means to discover hidden dangers and avoid accidents in time, and are also important tasks for the power plant personnel on duty.
