Abstract

The invention provides a current and time parameter detection system for a leakage current protector tester, and relates to the technical field of leakage current protector testers. The system comprises a leakage current protector tester, a first measurement module, a second measurement module, a leakage current detection amplification module, and a bistable flip-flop. The device has good universality, and can be used for detecting a leakage current protector tester imported abroad and having high accuracy, but also can adapt to leakage current protector testers which are produced by numerous manufacturers in China and have low precision or incomplete and standard technical data.

Description

technical field [0001] The invention relates to the technical field of leakage current protector testers, in particular to a leakage current protector tester current and time parameter detection system. Background technique [0002] The leakage current protection tester is mainly used for testing, detecting and calibrating the leakage current and leakage operation time parameters of the leakage current protector, also known as RCD (Residual Current Operated Protective Device). The accuracy of the leakage current protector tester is detected and calibrated by higher-level equipment according to the principle of value traceability or the uncertainty principle of 1 / 3 of the tested product. [0003] At present, there are many leakage current protector testers produced by domestic and foreign manufacturers in the market. When testing and calibrating these leakage current protector testers of different types and models, the above-mentioned higher-level special instruments and equi...
