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/T********8 《Series capacitor used in the power
system》
GB*******5 《Design specifications of shunt capacitor
device》
IEC ******1 ED4 ******1 《Series Capacitors for Power
System》
The meaning of the type model
Example: CAM5.******1W
That means: Benzyl toluene impregnating, film dielectric, HV
series capacitor, rated voltage is 5.5 kV , rated capacity is
**0kVar, single phase, outdoor.
Technical parameter
Rated voltage:3.8 ~*1kV.
Rated frequency: *0/*0Hz
Rated capacity: *0~**0kVar.
Loss tangent: ≦0.***3.
Number of phase: single phase.
Insulation level: *5/**5kV.
Discharge resistor: an internal discharge resistance is
equipped with capacitor, that will be reduced the terminal voltage
from √2Un to *0V 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 *1mm/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: **0% 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 **0% 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 ***0m. (Above ***0m,
use the plateau capacitor)
Temperature range: **0/D, pollution degree: IV.
There is no corrosive gas and vapor.
No strong mechanical vibration.
No explosion, flammable dangerous goods.
