HZS-BKS 10kV high-voltage reactive power automatic compensation device, according to the reactive load change of the distribution transformer, automatically switches the capacitor bank connected in parallel to the 3-20kV bus of the distribution transformer step by step to compensate the corresponding capacitive reactive power; It has the advantages of flexible site selection, easy installation, high degree of intelligence, high operating efficiency and long service life. It is suitable for real estate, chemical industry, metallurgical manufacturing, transportation, coal mining, and substation applications to improve power quality, reduce loss and energy saving, and improve the economic benefits of power supply enterprises.

HZS-BKS high-voltage grouping automatic reactive power compensation device automatically switches on and off the capacitor bank according to the voltage and reactive power of the power supply bus, and tracks the change of load for reactive power compensation, thereby providing power factor, improving power supply quality, and reducing power loss. Installed on the outlet bus side of a 35kv or 110kv substation, or installed in a 6, 10kv switchgear, and often installed in front of the control cabinet of a high-voltage motor in a working condition enterprise for on-site compensation.

This device is equipped with reactive power automatic compensation, automatic tracking of reactive power load changes, switching capacitor banks, improving power factor, and improving power quality; suppressing harmonic function, can be equipped with series reactor according to the harmonic situation given on-site to form an LC Circuit, suppression of harmonics; perfect capacitor bank protection, with over-voltage protection, under-voltage protection, over-current protection, zero-sequence voltage protection, capacitor branch unbalanced voltage protection

10kv reactive power compensation device structure

Reactive power compensation controller (PFC) and microcomputer capacitor protector (CXB), current transformer (CT), drop-out fuse (FU), lightning arrester (FV), discharge coil (TV), high-voltage AC vacuum contactor (KM) ), reactor (L), capacitor protection high-voltage fuse (according to capacitor bank configuration) and power capacitor bank (C) (according to user distribution load) and other parts.

Product one-time system diagram

working principle

The 10kv reactive power compensation device collects the A and C phase voltage signals by the system voltage transformer (PT), and the system current transformer (CT) collects the B phase current signal and transmits it to the HZS type reactive power compensation controller. After the controller sampling circuit, the analog signals of voltage and current are obtained, and then through A/D conversion, the digital quantities of voltage, current, etc. are obtained, and then the voltage, current, active power, and no Power, power factor, harmonic percentage and other parameters, and the system set point stored in the fixed memory (users can choose different control modes according to the above parameters. For example: according to reactive power + voltage, voltage, current, power factor Etc.) for comparison, the system decides under what circumstances to operate the capacitor bank, and performs the opening and closing of the capacitor bank through the high-voltage AC vacuum contactor, so as to achieve the purpose of automatically switching the capacitor bank and compensating the reactive power of the circuit. The supply and demand of reactive power on the network are automatically balanced on-site, which plays an important role in reducing line loss, improving power factor and system transmission capacity, and improving the quality of power supply in the distribution network.
