Abstract

The invention relates to automatic detection equipment of a heat breaker and an operation method thereof. The automatic detection equipment comprises the heat breaker, and a detection device for detecting the on / off state at take-off temperature and snap-back temperature of the heat breaker, wherein the detection device includes a probe for detecting the operation of the heat breaker, a heating core for providing working temperature to the heat breaker, a first thermistor for measuring and feeding back the temperature of the heating core and a control system; the probe is arranged at the output end of the heat breaker; the first thermistor is arranged on the surface of the heating core; the heating core is connected with the heat breaker through a thermal conductor; a second thermistor isarranged on the thermal conductor; and the control system is respectively and electrically connected with the heating core, the first thermistor, the second thermistor and the probe. By simulating theactual use condition of the heat breaker, the invention can rapidly and accurately determine whether the heat breaker meets the requirements. The invention has the advantages of simple and reasonablestructure, accurate detection and convenient operation.

Description

technical field [0001] The invention relates to a detection device, in particular to an automatic detection device of a thermal cutout and a working method thereof. Background technique [0002] When a thermal cutout is used as a temperature control device for quality inspection, it is generally necessary to detect the on-off state at the take-off temperature and rebound temperature. At present, in the detection of thermal cutouts, most of them adopt the form of oven or simple heating plate. The actual use of the thermal cutout is that the surface is in contact with the metal, and the metal will operate within a specified time after the metal reaches the temperature. The oven test cannot reflect the actual use of the thermal cutout. The oven heats the whole of the thermal cutout, not the surface. The test results only reflect the temperature of the bimetal strip, not the actual application of the thermal cutout, and there is a phenomenon of misjudgment. The other is the fo...
