Low/high Temperature Test Chamber for high-low temperature performance test of circuit breakers

As a safety protection device, the circuit breaker is mainly used to cut off the circuit to prevent fire and other safety accidents caused by overload or short circuit of electrical equipment. In actual use, the circuit breaker may be affected by different environmental conditions such as high temperature and low temperature. If its high-low temperature resistance performance is insufficient, it may cause its failure or unstable operation, thus failing to protect electrical equipment and personal safety. Therefore, the high-low temperature resistance test of the circuit breaker can evaluate its working reliability in different temperature environments, so as to ensure its normal operation and safety performance.

The high-low Temperature Test Chamber can be used for high-low temperature environmental tests of circuit breakers to verify their performance and safety under extreme temperature conditions. The following is the application and test procedures of the high-low Temperature Test Chamber in the high-low temperature resistance test of the circuit breaker.

application

The application of the high-low Temperature Test Chamber in the high-low temperature resistance test of the circuit breaker includes:

• High temperature test: Place the circuit breaker in a high temperature environment to simulate high temperature climate conditions and test its thermal stability and heat resistance.

• Low temperature test: Place the circuit breaker in a low temperature environment to simulate cold weather conditions and test its cold resistance and operational performance.

• Temperature cycle test: place the circuit breaker in a high-low temperature cycle environment to simulate temperature changes and test its deformation and damage.

experiment procedure

1. Put the circuit breaker to be tested into the high-low Temperature Test Chamber. Before placing, make sure that the circuit breaker has removed residual heat or moisture, and take anti-static measures.

2. According to actual needs, set the test conditions of high temperature, low temperature or temperature cycle. These conditions include temperature range, rate of temperature change, soak time, etc.

3. Start the high-low Temperature Test Chamber according to the set conditions and start the test. During the test, the high-low Temperature Test Chamber will automatically control the temperature and perform high-low temperature cycles within the set temperature range.

4. During testing, the circuit breaker needs to be monitored to ensure its performance in high-low temperature environments. The monitoring parameters include the operating performance of the circuit breaker, trigger current, withstand voltage, etc.

5. When the test is complete, close the high-low Temperature Test Chamber and take out the test equipment. Data analysis and evaluation is then carried out.

In conclusion, high-low Temperature Test Chambers can provide important support for the quality control of circuit breakers and ensure their performance and safety under extreme temperature conditions.
