Precautions for using film capacitors

1. The use of film capacitors has been spread in various fields of the industry. In the process of use, only timely attention to any problems in the use process can ensure that there will be no problems during use.

When installing the film capacitors, the wiring of each capacitor is to select a separate cord to connect with the busbar. Do not use a harder busbar to connect, thus preventing damage to the product during assembly stress. In addition, any problematic contact during the loop process of the capacitor may cause damage due to heat generation. When the connection is successful, it should be measured in time to ensure that the entire neutral point is not grounded to cope with the insulator. Keeping the correct use steps while using the installation can prevent these phenomena from happening;

2. When using it, it is to allocate the use of the primary capacity. In the process of distribution, the balance between the two is guaranteed, and the current error is supplemented, but the deviation is not too large. In particular, the wiring of the individual compensation capacitors should be reasonably ensured throughout the use. When the induction motor is started or passed through the varistor, the power is connected in time to prevent the switch or fuse between the two devices. Phenomenon, further preventing the occurrence of bad phenomena;

3. The impedance of the film capacitor is inversely proportional to the frequency. As the frequency increases, the loss also increases. Measures should be taken to limit the harmonics and inrush currents in the circuit. Film capacitors must always produce heat. Pay special attention to ventilation and cooling. After the reactive power compensation device is installed, during the test run, the system should be tested and over-voltage, over-current, oscillation, harmonics, etc. should be taken in time. The normal operation of the capacitor is very necessary.
