A kind of interlock that is used on the high voltage distribution installation comprises: actuator, STATEMENT OF FEDERALLY SPONSORED, and locking piece; Said actuator is suitable for being connected with breaker assembly, and said locking piece is suitable for being connected with switch component; Said STATEMENT OF FEDERALLY SPONSORED is arranged between said actuator and the said locking piece; Said actuator drives an end of said STATEMENT OF FEDERALLY SPONSORED, and the other end of said STATEMENT OF FEDERALLY SPONSORED is locked with said locking piece mutually.
The present technique scheme also has following subsidiary characteristic:
Said actuator comprises: the operating axis that is connected with said breaker assembly, and be arranged on the cam on the said operating axis.
Said locking piece comprises: the operating axis that is connected with said switch component, and be arranged on the wheel cover on the said operating axis.
Said take turns to put be provided with at least two grooves.
Said STATEMENT OF FEDERALLY SPONSORED comprises: ejector pin seat and be arranged on ejector pin and the reseting pressuring spring on the said ejector pin seat.
Said ejector pin seat is fixed on the said power distribution equipment casing.
Said ejector pin seat is provided with a slideway, and said ejector pin is provided with a snap ring, and said reseting pressuring spring is enclosed within on the said ejector pin, and is resisted against between the bottom of said snap ring and said slideway.
The operating axis that is connected with said breaker assembly is provided with a cam; The operating axis that is connected with said switch component be provided with one have a groove the wheel cover; Said breaker assembly operating axis rotates and can drive said cam rotation; The rotation of said cam promotes one of said ejector pin and holds level with both hands and move; The other end of said ejector pin inserts in the said groove of taking turns cover.
Said breaker assembly operating axis counter-rotation can drive said cam rotation; Said reseting pressuring spring resets said ejector pin, and the other end of ejector pin is shifted out from the groove of affiliated wheel cover.
The interlock of the utility model is simple in structure, low cost of manufacture, but can effectively breaker assembly and switch component be interlocked.Make switch component close a floodgate and put in place, reduced because of loose contact causes electric elements burn, the situation of fault or electric leakage.For this reason, high voltage distribution installation is overhauled or other whens operation the situation that can not cause the staff to get an electric shock because of the electric leakage of power distribution equipment the staff.Owing to be high-tension electricity, make the staff injured probably in case get an electric shock, in addition dead.For this reason, the present technique scheme has been strengthened the guarantee to staff's personal safety.

Embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed description:
With reference to Fig. 1 and Fig. 2; A kind of interlock that is used on the high voltage distribution installation; Said high voltage distribution installation comprises: explosion-resistant enclosure 1, be arranged on cabinet door 2 on the said explosion-resistant enclosure, be arranged on breaker assembly 3 and switch component 4 in the said explosion-proof casing, the staff can manually break off high-tension circuit through disconnecting switch operation assembly 4.Said breaker assembly 3 is the protection assembly, and when problem such as short circuit occurring when high-tension circuit, breaker assembly 3 can break off high-tension circuit automatically, thereby prevents that each electric device from burning because of short circuit or damage.Be provided with an interlock 5 between said breaker assembly 3 and the said switch component; Said interlock 5 comprises: actuator 6, STATEMENT OF FEDERALLY SPONSORED 7, and locking piece 8; Said actuator 6 is connected with said breaker assembly 3, and said locking piece 8 is connected with said switch component 4; Said STATEMENT OF FEDERALLY SPONSORED 7 is arranged between said actuator 6 and the said locking piece 8; Said actuator 6 drives an end of said STATEMENT OF FEDERALLY SPONSORED 7, and the other end of said STATEMENT OF FEDERALLY SPONSORED 7 is locked with said locking piece 8 mutually.
Referring to Fig. 2, said actuator 6 comprises: the operating axis 61 that is connected with said breaker assembly 3, and be arranged on the cam 62 on the said operating axis 61.Said locking piece 8 comprises: the operating axis 81 that is connected with said high-voltage switch gear assembly 4, and be arranged on the wheel cover 82 on the said operating axis 81.The said cover 82 of taking turns is provided with at least two grooves 821.Said STATEMENT OF FEDERALLY SPONSORED 7 comprises: ejector pin seat 71 and be arranged on ejector pin 72 and the reseting pressuring spring 73 on the said ejector pin seat 71.Said ejector pin seat 71 is fixed on the said explosion-resistant enclosure 1.Said ejector pin seat 71 is provided with a slideway 711, and said ejector pin 72 is provided with a snap ring 721, and said reseting pressuring spring 73 is enclosed within on the said ejector pin 72, and is resisted against between the bottom of said snap ring 721 and said slideway 711.
