Influence of working environment of reactive power compensation deviceInfluence of working environment of reactive power compensation device

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...

    Automation level and reliability of reactive power compensation devices

    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...

    What is the difference between a static reactive compensation controller and a dynamic reactive compensation controller?

    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...

    Power capacitor installation precautions

    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...

    Cause of damage

    Abstract: As power capacitors are put into operation more and more, but poor management and other technical reasons often lead to damage to power capacitors and explosion. There are several reasons for this: breakdown of internal components of the capacitor; damage to the insulation of the capacitor; poor sealing and oil leakage; explosion of the capacitor caused by charge closing...

Is dynamic compensation an active filter? Is passive filtering an anti-harmonic product?

Dynamic compensation refers to reactive power compensation products with a response time of 20ms. Active filtering APF uses a semiconductor circuit to implement the filtering function; passive filtering is achieved by reactance and capacitor resonance point configuration, and anti-harmonic refers to suppression. Wave, prevent compensation capacitor overload. Therefore, the functions implemented by the above products are different.
