Abstract

The invention belongs to the technical field of measurement and analysis, and particularly relates to a relay accelerated storage degradation experiment parameter test analysis system and a test method, and is suitable for a universal electromagnetic relay. The system comprises an accelerated degradation experiment environment simulation experiment box, a load box, a relay storage degradation parameter measurement and control box, a lower computer, an upper computer and a PC. The storage degradation parameter test system has the function of testing the action voltage, the action time, the release voltage, the release time, the bounce time, the coil resistance and the contact resistance (or contact voltage drop) of the relay in the accelerated storage degradation experiment process. The method comprises the steps that firstly, the relay is placed in the accelerated storage degradation experiment environment simulation constant-temperature box, the humidity and the temperature needed by the accelerated storage experiment are set in the lower computer, and the upper computer calculates, stores and analyzes collected data for evaluating the storage reliability of the electromagnetic relay.

Description

technical field [0001] The invention relates to the technical field of measurement and analysis, in particular to a relay accelerated storage degradation experimental parameter test and analysis system and test method, which are suitable for general electromagnetic relays. Background technique [0002] The electromagnetic relay controls the circuit through the connection or disconnection of the contacts. It has the advantages of high conversion depth and good physical isolation performance. It is widely used in automatic control systems, power protection systems and communication systems, and plays a role in control, detection, protection and adjustment. It is one of the indispensable basic elements of cutting-edge national defense technology, advanced industrial and civilian equipment. As an important device of the national defense military weapon control system, the electromagnetic relay is often in the same storage state as the weapon system, and its storage reliability h...
