Utility model content
The purpose of this utility model is to provide a kind of power capacitor, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following solution: a kind of power capacitor, comprise lead-in wire and shell, the outside of described lead-in wire is provided with sleeve pipe, described sleeve pipe and shell are cast into one, the centre of described shell is threaded connection and is provided with oil inlet pipe, the centre of the downside of described oil inlet pipe is holding chamber, described holding chamber inside is provided with capacitance body, the both sides of described holding chamber are respectively equipped with release of pressure room and failture evacuation room, described failture evacuation chamber interior is provided with troubleshooting equipment, contact portion between described holding chamber and release of pressure room is provided with pressure relieving valve by bolt, gas outlet is provided with above described release of pressure room.
Preferably, described troubleshooting equipment comprises fuse-link and jockey, is electrically connected between described fuse-link and capacitance body.
Preferably, described capacitance body is divided into upper strata capacitance body and lower floor's capacitance body.
Preferably, described pressure relieving valve adopts one-way control valve.
Preferably, watch window is provided with above described failture evacuation room.
Preferably, be threaded connection above described oil inlet pipe and be provided with safety cap.
Compared with prior art, the beneficial effects of the utility model are: this power capacitor, by the outside being arranged on separately capacitance body of troubleshooting equipment, can change separately, handled easily, increase work efficiency; By the setting of pressure relieving valve, the generation of exploding can be prevented, improve security performance.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1-2, the utility model provides a kind of technical scheme: a kind of power capacitor, comprise lead-in wire 1 and shell 2, the outside of lead-in wire 1 is provided with sleeve pipe 3, sleeve pipe 3 and shell casting 2 are made and are integrated, the centre of shell 2 is threaded connection and is provided with oil inlet pipe 4, the centre of the downside of oil inlet pipe 4 is holding chambers 5, holding chamber 5 inside is provided with capacitance body 6, the both sides of holding chamber 5 are respectively equipped with release of pressure room 7 and failture evacuation room 8, inside, failture evacuation room 8 is provided with troubleshooting equipment 9, contact portion between holding chamber 5 and release of pressure room 7 is provided with pressure relieving valve 10 by bolt, gas outlet 11 is provided with above release of pressure room 7, troubleshooting equipment 9 comprises fuse-link 91 and jockey 92, by being electrically connected between fuse-link 91 and capacitance body 6, capacitance body 6 is divided into upper strata capacitance body 61 and lower floor's capacitance body 62, if want that the capacity expanding capacitance body 6 can be connected upper strata capacitance body 61 and lower floor's capacitance body 62 by jockey 92, or upper strata capacitance body 61 breaks down to use and can connect lower floor's capacitance body 62 as subsequent use, pressure relieving valve 10 adopts one-way control valve, the set point of pressure relieving valve 10 is exceeded just to release of pressure room 7 blowdown presssure when the pressure of capacitance body 6 inside is excessive, discharge from gas outlet 11, and the air of outside can not enter into the inside of capacitance body 6, failture evacuation room 8 is provided with watch window 12 above, convenient device service condition of observing inside, failture evacuation room 8, troubleshooting equipment can be changed by watch window 12, oil inlet pipe 3 is threaded connection above and is provided with safety cap 13, need to open safety cap 13 when oiling, safety cap 13 is tightened time no.
Operation principle: when using this power capacitor in work; just can be used by the lead-in wire 1 inside joint sleeve 3; if open safety cap 13 after liquid Jie of the inside has lacked to be situated between from oil inlet pipe 4 injection liquid; if electric current is excessive and then cause temperature too high; so fuse-link 91 will blow; and then protection capacitance body 6; the fuse-link 91 more finished changing subsequently; can not use if upper strata capacitance body 61 breaks down; lower floor's capacitance body 62 is connected by jockey 92; do not affect overall capacitance then use, when internal pressure is excessive by pressure relieving valve 10 discharge pressure.
Although illustrate and described embodiment of the present utility model, for the ordinary skill in the art, be appreciated that and can carry out multiple change, amendment, replacement and modification to these embodiments when not departing from principle of the present utility model and spirit, scope of the present utility model is by claims and equivalents thereof.
