Reactor is a very important component in capacitor cabinet.
Series reactor and parallel reactor are commonly used in power system. Series reactor is mainly used to limit short circuit current
High - order harmonics in the power grid are limited in series or in parallel with capacitors in the filter. 220kV, 110kV, 35kV, 10kV power grid
The reactor is used to absorb the charge capacitance reactive power of the cable line. The operating voltage can be adjusted by adjusting the number of shunt reactors. Ultrahigh pressure and
The reactor has a variety of functions to improve the operating conditions of the reactive power of the power system, including:
(1) capacitance effect on light no-load or light load lines to reduce power frequency transient overvoltage.
(2) improve the voltage distribution on long transmission lines.
(3) the reactive power in the line should be balanced on the spot as much as possible when the load is light, so as to prevent the irrational flow of reactive power and reduce the power on the line
(4) reduce the steady-state voltage of working frequency on the high voltage bus when the large unit is parallel with the system, which is convenient for the generator to be parallel at the same time.
(5) to prevent the self-excitation resonance of the generator with long lines.
(6) when the neutral point of the reactor is adopted through the small reactance grounding device, the small reactor can also be used to compensate the circuit phase to phase and ground capacitance to accelerate the potential power supply
The flow is automatically extinguished for ease of use.
