Service life test system for self-recovery thermal circuit breaker

Abstract

The utility model provides a self-recovery thermal circuit breaker service life test system, which comprises a power supply, a heater and a counter, the power supply, the heater and a tested self-recovery thermal circuit breaker are connected in series to form a test loop, and the heater supplies heat to the self-recovery thermal circuit breaker so as to change the on-off state of the test loop; and the counter is used for recording the on-off times of the test loop. The utility model provides an effective and convenient test system for testing the service life of a self-recovery thermal circuit breaker, and after being assembled, the test system can automatically carry out a test of multiple cyclic actions on the service life of the self-recovery thermal circuit breaker so as to detect whether the self-recovery thermal circuit breaker meets the requirements of basic safety and basic performance of ME equipment, thereby greatly improving the test efficiency of the self-recovery thermal circuit breaker, and improving the test efficiency of the self-recovery thermal circuit breaker. And the method has positive significance on quality supervision and production monitoring of ME equipment.
