inside fuse high voltage capacitor one factor was puncture ,other factor will discharge power then cut off fuse ,it work again

High voltage power capacitor (Internal fuse type)

High voltage shunt capacitor

power capacitor 

Reference Standard

IEC 60871; JIS C 4902; CNS1372 / 3739

Construction

These capacitors are used all film dielectric, insulation oil (PXE; M/DBT or C101) and foil folded construction.

Using Condition

1. Temperature range: -25°C~+50°C

2. Altitude: ≤1000m

Features

1. Low dissipation factor, low temperature rise, long service life

2. Stable capacitance with little varision due to temperature

3. Impregnated with high insulation strength and non-PCB biodegradable fluid in vacuum tank

4. Internal fuse capacitor mainly has more safety, higher reliability, less installation space, lower installtion and maintance costs.

Specification and performance

1. Frequency: 50Hz / 60Hz

2. Capacitance tolerance: -5% ~ +15%

3. Max. permissible voltage: 110% of rated voltage (average voltage in every 24hrs) / 120% of rated voltage (5 min / max. 200 times) / 130% of rated voltage (1 min / max. 200 times)

4. Max. permissible current: 135% or rated current

5. Dissipation factor: less than 0.05% or 0.5W/kVAR

6. Temperature rise: below 25°C at ambient temperature 35°C

7. Insulation resistance: above 1,000 MΩ

8. Tested voltage between terminals: rated voltage x 2Vac, 60sec

9. Tested voltage between terminals and case: depend on rated voltage, test value is according to the requirements of standards.

10. Impulse voltage (BIL):  depend on rated voltage, test value is according to the requirements of standards.
