Description

Technical Field

[0001] This utility model relates to the field of testing instrument technology, and in particular to a relay protection tester that effectively extends service life. Background Technology

[0002] The power system consists of power generation, transmission, transformation, distribution, and consumption. Its safe and stable operation is crucial to the national economy and social life. Relay protection devices, as the safety guardians of the power system, can quickly and accurately operate when system faults and anomalies occur, disconnecting faulty equipment, preventing the escalation of accidents, and ensuring the safe operation of the power system. Relay protection testers are specialized testing equipment designed to ensure the reliable and accurate operation of relay protection devices. They can simulate various power system fault conditions, input different types, amplitudes, and frequencies of current and voltage signals to the relay protection devices, and then detect the operation of the relay protection devices, including parameters such as operating time, operating value, and return value, to determine whether the relay protection devices meet design requirements and operating standards. Furthermore, before newly installed relay protection devices are put into operation, they need to be comprehensively debugged and inspected using testers to ensure their reliable performance. During the periodic verification and maintenance of operating relay protection devices, testers are also needed to check whether their various indicators still meet the requirements.

[0003] By employing high-quality materials and electromagnetic compatibility design, the relay protection tester can maintain stable performance during long-term use. Its reliable hardware design and perfect software system can reduce test interruptions and errors caused by its own failures, improve the efficiency and quality of testing work, and extend its service life. However, during daily use, handling and storage, it is subject to external forces such as collisions and scratches, which can easily cause dents, cracks and damage to the tester's casing.
