温控器的使用寿命和材质分类

Snap action thermostat material for the class: ceramic body porcelain (95); Bakelite (bakelite); PPS body
Snap action thermostat working life
The thermostat sample connected to the rated voltage, the maximum working current (deviation plus or minus 5%), the thermostat to rise and cooling contactor opening and closing test, the maximum frequency 6 times/min, closing time more than 1 second. Record closed once a day as a cycle, cycle count, not occur due to arc electrode short circuit and charged a short circuit, then check the performance. Sample cycle is 100000 times of durability test shall meet the following performance metrics:
Action changes to test the initial value of the temperature under 100 ℃ to + / - 5 ℃, above 100 ℃ to + / - 5%;
More than 100 M Ω insulation resistance (use DC500V DC500V measuring insulation resistance meter plus nominal voltage
