How to improve the reliability of the microcomputer relay protection test set?
The reliability of the microcomputerrelay protection test set is a basic requirement for relay protection devices, mainly manifested as no misoperation and no refusal to operate. The reliability of the microcomputerrelay protection test set is related to many factors, such as the principle, craftsmanship, and maintenance level of the relay protection test set. How can the reliability of the microcomputer relay protection test set be improved?
1. Strictly inspect the relay protection device and its secondary circuit. Strict inspection can timely discover problems and avoid accidents.
2. Seriously handle the acceptance work of relay protection. After the commissioning of the relay protection test set is completed, carry out acceptance strictly according to requirements, and have professionals conduct the complete protection group test and switch closing/tripping test. Ensure that components and wiring return to normal.
3. Improve the accuracy of relay protection operation. After learning the protection principles and secondary drawings, operators should check and familiarize themselves with the on-site secondary circuit terminals, relays, signal drop flags, and pressure plates. Strictly implement the "two tickets" and carry out the protection safety measure ticket, and operate according to the relay protection operation regulations.
