Operational reliability is an important parameter of T73 12v 5 pin relay. T73 12v 5 pin relay is a component with control function and relay protection. How to improve the working performance of T73 12v 5 pin relay?
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. superior. 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 T73 12v 5 pin relay protection. After the relay protection is debugged, strictly self-inspect, professionally accept, and then submit the wiring list. The factory will organize the maintenance, operation, and production departments to protect the whole group. After passing the test, switch on and off test, confirm that the disconnection, components, signs, pressure plate, 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. The content of T73 12v 5 pin relay protection inspection is as follows:
1. The protection plate and automatic device are fully invested according to the requirements of the production plan;
2. The position of the switch and the pressure plate are correct, and the wiring of each circuit is normal, and there is no looseness, heating, and burnt smell;
3. Good fuse contact;
4. T73 12v 5 pin relay wiring is intact, the contact is live, there is no big jitter and burn, and the coil and additional resistance are not overheated;
5. CT and PT circuits have no fracture or short circuit respectively;
6. The display of the oscilloscope lamp and the operation monitoring lamp is normal;
7. The counter parameters meet the regulations;
8. The signs, alarm bells, and accident sound are in good condition;
9. After the microcomputer protects the printer, the time and parameters of the report should be checked. If any abnormality is found in the report, the relay protection personnel should be notified in time to deal with it.
Fourth, strict inspections and inspections of the T73 12v 5 pin relay relay protection device and its secondary circuit are important means to discover hidden dangers in time and avoid accidents, and are also important tasks for the power plant staff on duty.
