Capacitor is consist of core, shell, outgoing bushing and etc., two side of the container is welded
install bracket, the other side bracket is equipped with earthing bolt. Core of capacitor is consist of several
elements and insulation part. To suitable for different voltage, core is consist of several small element in
parallel and then in series. Inside the capacitor there is discharge resistor, outer shell is welded by
stainless steel.
HV shunt capacitor is suitable for 50Hz AC power system, used for improve power frequency system
power factor, reduce line loss, improve power supply voltage quality, increase transformer active power
output
4.1 Bushing: Adopts cold pressure, antifouling sleeve, creepage distance not less than 31mm/kV.
4.2 Mature internal fuse technology
4.2.1 After test, internal fuse can isolate the fault elements during 0.2ms, energy release of the fault
point will not more than 0.3kJ, other good elements will not be influenced.
4.2.2 Advanced concealed internal fuse structure, use oil gap for arc extinction, reduce the
possibility of capacitor tank blasting.
4.2.3 Internal fuse protection and relay protection with perfect combine standards, to ensure the safe
and reliable operation of the whole device.
4.3 Insulation margin is large, after test, the capacitor can withstand the 4Un instant effect, tolerance
2.5Un 5min.
4.4 Liquid medium: 100% benzyl toluene (M/DBT), the liquid has excellent low temperature
performance and partial discharge performance.
4.5 The main insulation adopts compound insulation structure, which ensures excellent electrical
performance, but also has a certain mechanical strength, to ensure that the insulation of capacitor bank to
ground under no protection 100% reliable.
4.6 Good sealing performance: the annual leakage rate is less than 0.1%, through the automatic
argon arc welding, kerosene test leak, vacuum leak test, thermal aging and other measures to ensure the
sealing performance of the capacitor.
4.7 Partial discharge level: the extinguishing voltage
