Abstract: The protection, safety and automatic device needs to measure the action conditions and time in the check, accept and regular checking work. The primary protection export detection device was carried out improvement to increase the function of obtaining fault initial time for relay protection tester, which could measure the specific time for the action of different time about protection, and to increase the direct current (DC) power supply circuits to solve the problem of not detecting for instrument without corresponding DC Power supply for protection device export plate, which could achieve cluster definition of export plate detection terminal, reducing to 24 roads, and developed touch-screen functions. Each input abbreviation could be modified to more flexibly adapt to different situations of protection export plate. The pulse detection circuit of export plate was replaced to improve the input resistance, so as to make it more simple and reliable.
Key words: detection device; export pressing plate; export matrix; micro-computer measurement; improvement
