This mainly refers to the influence of external factors such as temperature, humidity, rain, dust, and small animals. There are three types of reactive power compensation devices installed, namely, the compensation cabinet in the power distribution room, the compensation device for the box type, and the on-column compensation box for the common distribution of the line. The former two can be regarded as the indoor installation form, and the on-column compensation box of the common distribution is an outdoor installation form, and its working environment is the worst...

The early reactive power compensation capacitors have a low degree of automation, and it is not possible to judge the changes of the grid operating parameters. It is necessary for the operating personnel to perform the switching operation during the operation. When the frequency of network changes is high, the operation is more frequent, and the operating personnel will feel the difficulty and increase the workload. With the rapid development of computer technology...

Static compensation is only a fixed (in order) capacitance according to the power factor, and the dynamic compensation is based on the difference in power factor and the selected switching capacitance is incorrect. The reactive power compensator is a kind of compensation device. The role played by the electronic power supply system is to improve the power factor of the power grid and reduce the loss of the power supply transformer and the transmission line...

1. When installing the capacitor, it is better to use a separate flexible wire to connect the busbar to each bus. Do not use a hard busbar connection to prevent damage to the capacitor casing caused by assembly stress and damage the oil leakage caused by the seal. 2. Any bad contact in the capacitor circuit may lead to...

Abstract: In the power grid, voltage quality is closely related to reactive power compensation. A reasonable configuration of the reactive power compensation device can improve the voltage quality. Reactive power compensation devices improve voltage quality by reducing the loss of voltage in the line. The reactive power compensation device can reduce the electricity cost of the power user by increasing the power factor, and can realize the economic benefit of the power user very significantly....

Abstract: In daily life and industrial production, capacitor failures are not uncommon. On the one hand, because capacitors are lossy components, long-term work leads to structural aging; on the other hand, it is mainly human factors, improper operation and defective design of the capacitor itself, resulting in very short service life.......
