Platform capacitor unit 6 is divided into 4 groups, every group 32, is separately mounted on insulated platform 7, and the current potential of four insulated platforms 7 is
It is independent mutually, physical isolation is realized to four group capacitor units 6 in this way.On electrical wiring, every two capacitor units 6
The capacitor unit 6 in parallel with another two again in parallel is composed in series a branch, and 8 branches, Shang Jiping are shared on each platform
The branch of platform is attached with corresponding branch on subordinate platform respectively, then whole capacitor includes 8 electric branch circuits in parallel,
8 string 16 of composition and electric loop.By calculating, when capacitor unit 6 occur electrode insulation breakdown and to shell puncture this
When the extreme fault condition of sample, the energy of injection faulty capacitor unit 6 is 11.85kWs, is less than the specified value of 15kWs,
Showing can be to avoid the generation of capacitor bursting accident using the compact type shunt capacitor technical solution of the art of this patent.
