In the power system of industrial enterprises, it is common to install power capacitors for reactive power compensation. However, during the operation of the compensation capacitor, fire and explosion accidents may occur, which will adversely affect the enterprise. So how should companies avoid fire and explosion of compensation capacitors? The editor will introduce it in detail in the following article.
1. The compensation capacitor fails to pay, and its parameters will change greatly. Through the real-time monitoring system, data such as voltage, current, capacity, and dielectric loss of the capacitor can be monitored to determine whether the compensation capacitor has failed.
2. Strengthen the number of inspections, inspections and maintenance of compensation capacitors. At the same time, when the compensation capacitor is running, operations such as charging closing and frequent switching should be avoided.
3. The centrally installed compensation capacitor should ensure the ventilation, rainproof and dustproof of the capacitor room.
4. The compensation capacitor bank, usually using cyclic switching, can extend the delay interval of the automatic compensation device controller, reduce the number of switching times of the capacitor, and reduce its failure rate.
5. The existence of grid harmonics will affect the operation of compensation capacitors. When there are harmonics in the power grid, filter reactors or active filters should be selected for harmonic control.
6. Selecting high-quality compensation capacitors for compensation can greatly reduce its failure rate, thereby ensuring the stable operation of the capacitor.
Because of the reactive power problem, the company has to install capacitors for reactive power compensation. However, when the compensation capacitor is running, fire and explosion accidents must be avoided.
