High Voltage Capacitor 9.5kv Single Phase Power Factor Correction
Capacitor
1.Overview of 9.5kv 3 Phase 50 kvar High Voltage Shunt
Capacitor
Medium voltage shunt capacitor/High voltage shunt capacitor is composed of a pack, a case, outlet porcelain busing, etc.
The two sides of stainless steel case are welded with hanging
brackets for installation, and one hanging bracket is equipped with
a grounding bolt. In order to adapt to various voltages, the pack
is composed of several small elements connected in parallel and
series. The capacitor is equipped with a discharge resistor
2. Function of 9.5kv 3 Phase 50 kvar High Voltage Shunt Capacitor

3. Main features of 9.5kv 3 Phase 50 kvar High Voltage Shunt Capacitor
- 3.1 Casing: Cold-pressed, anti-fouling type casing is adopted, and
the creepage distance is not less than 31mm/kV.
- 3.2 Mature internal fuse technology.
- 3.2.1 After testing, the internal fuse can isolate the faulty
component within 0.2ms, the release energy of the fault point is
not more than 0.3kJ, and the remaining intact components are not
affected.
- 3.2.2 Advanced concealed internal fuse structure, using oil gap arc
extinguishing, reducing the possibility of blasting the capacitor
case.
- 3.2.3 The internal fuse protection and relay protection have
perfect coordination standards to ensure the safe and reliable
operation of the entire device.
- 3.3 Liquid medium: 100% insulation oil (NO PCB) is used. This
liquid has excellent low temperature performance and partial
discharge performance.
- 3.4 The main insulation adopts a composite insulation structure,
which not only guarantees excellent electrical performance, but
also has a certain degree of mechanical strength, which ensures
that the insulation of the capacitor complete set of devices is
100% reliable without protection.
- 3.5 Good sealing performance: The annual leakage rate is less than
0.1%, and the sealing performance of the capacitor is guaranteed
through measures such as automatic argon arc welding, vacuum leak
testing, and thermal aging.
- 3.6 Partial discharge level: the extinguishing voltage is not less
than 1.5Un, and each capacitor is tested for partial discharge
during production.
