High Voltage Series Capacitor
HV Series Capacitor

Application
The product is connected in series on the AC power system to compensate for the power line inductance, reducing line voltage drop, increased transmission capacity, to improve line stability.
Implementation of standards
GB/T6115-2008 《Series capacitor used in the power system》
GB50227-95 《Design specifications of shunt capacitor device》
IEC 60143-1 ED4 2004-01 《Series Capacitors for Power System》
The meaning of the type model
Example: CAM5.5-500-1W
That means: Benzyl toluene impregnating, film dielectric, HV series capacitor, rated voltage is 5.5 kV , rated capacity is 500kVar, single phase, outdoor.
Technical parameter
Rated voltage:3.8 ~21kV.
Rated frequency: 50/60Hz
Rated capacity: 50~800kVar.
Loss tangent: ≦0.0003.
Number of phase: single phase.
Insulation level: 65/125kV.
Discharge resistor: an internal discharge resistance is equipped with capacitor, that will be reduced the terminal voltage from √2Un to 50V or less within 5 min after the capacitor is disconnected from the grid.
Capacitance tolerance:-2%~+2%.
Features:
Bushing: Bushing is cold pressed, pollution proof, creepage distance is more than 31mm/kV.
Stable internal fuse technology
(1)     The internal fuse could isolate the fault element under 0.5√2Un~2.6√2Un in 0.2Us through test, released energy at the failure point is not greater than 0.3KJ, the other components is not affected.
(2)     Advanced concealed fuse structure, which uses oil gap arc, which reduces the explosion possibility of capacitor tank shell.
(3)     Complete standard is used between internal fuse protect and relay protect, which makes sure safe and reliable operation of the whole device, and prevents capacitor from explosion.
Great insulation tolerance, test shows that capacitor could withstand 4Un transient effects and 2.5Un in 5 min.
Liquid dielectric: 100% M/DBT, which has excellent low temperature features and partial discharge performance.
Main insulation uses complicated insulating structure, which guarantees the excellent electrical performance and mechanical strength, and guarantees that the insulation capacitor device to earth is reliable 100% without protection.
Good sealing performance: Leakage rate per year is less than 0.1%.the sealing performance is guaranteed by automatic TIG Welding, Kerosene leak testing, vacuum leak test and aging.
High partial discharge level, extinguishing voltage is not less than 1.5Un, and factory test of each capacitor includes partial discharge test.
Service condition:
The capacitor can be used indoor or outdoor.
The altitude of the site is not more than 2000m. (Above 2000m, use the plateau capacitor)
Temperature range: -40/D, pollution degree: IV.
There is no corrosive gas and vapor.
No strong mechanical vibration.
No explosion, flammable dangerous goods.
