Abstract

The invention relates to the field of electrical equipment detection, in particular to a full-performance detecting system of a magnetic latching relay and a detecting method of the full-performance detecting system of the magnetic latching relay. The detecting system comprises a main control panel, an auxiliary control panel and a resistive load box, wherein the auxiliary control panel is communicated with the main control panel through a network port, the auxiliary control panel controls the resistive load box to work by controlling an air switch, and the main control panel is connected with the magnetic latching relay. An ongoing full-performance test of the magnetic latching relay comprises an initial operation voltage, a returned value voltage test, an operation time test, a four probe method and high current method coil resistance test, a contact temperature-rise test, a mechanical life test, an electrical endurance test and an overload test. The full-performance detecting system is simple in wiring, capable of automatically finishing an electrical performance test, a safety performance test and a service life test without manual intervention, comprehensive in test items, and simple in test process.

Description

technical field [0001] The invention relates to the field of power equipment testing, in particular to a system and a method for detecting the full performance (electrical performance, mechanical performance, life and environmental performance) of a magnetic latching relay used in an electric energy meter in a power system, in particular to a magnetic latching relay The full performance detection system and detection method thereof. Background technique [0002] With the rapid development of smart grid, the consumption of smart energy meters has increased rapidly. As a key link in electric energy measurement, smart electric energy meters need to be verified by the verification department before they can be used. Not only their measurement performance must meet the requirements, but their safety and reliability must also be guaranteed. The magnetic latching relay is one of the main components of the smart energy meter. Its quality essentially determines the quality of the wh...
