Film capacitor protection

Capacitance is an important electronic component in the circuit, so we must pay attention to protect it when using it, and extend its service life as much as possible. At the time of purchase, we can test the withstand voltage and leakage current, and do not let go of any tiny places. These tests can help you detect the capacitance of the capacitor, so as to avoid damage to the capacitor and the appliance caused by the low capacitance.

1. When using, it is necessary to strengthen the inspection and inspection of the film capacitors, so as to make a regular inspection time period, check whether the housing, mounting bracket and connection point of the capacitor are firmly fixed, if the casing of the film capacitor is damaged, etc. In the case of the situation must stop running, so as to avoid accidents, but also pay attention to dust cleaning and cleaning.

2. Pay attention to the operating temperature of the capacitor. Under normal circumstances, pay attention to the temperature of the outer casing of the parallel capacitor of the film capacitor. If the temperature is too high, you must find out the specific cause and handle it in time.

To strictly control the voltage of the capacitor, the voltage of the capacitor usually has its own operating law, and should not exceed its rated range, otherwise the temperature of the capacitor is too high to increase its aging speed. The higher the voltage, the faster the aging, so the shorter the service life. It is very necessary to do a good job of the current protection measures, so don't underestimate.
