Description

Interlocking device for earthing switch operation of switch cabinet
Technical field
The utility model relates to a kind of interlock, particularly a kind of interlocking device for earthing switch operation of switch cabinet.
Background technology
Switch cubicle is used for connecting, disconnects and protects supply line, and cooperates the equipment of realizing the excision faulty line with relaying protection.Usually be equipped with a ground connection knife switch in the switch cubicle, when supply line or equipment break down and normal maintenance earthed switch ground connection must be protected life safety with this.In supply line, have only after earthed switch ground connection, just think safe.
Owing to be covered with high-tension circuit in the switch cubicle, it is breakneck when the ground connection cutter of operating personnel in switch cubicle inside is in gate-dividing state (the inner energising of switch cubicle) the cabinet door of switch cubicle being opened, in order to eliminate this type of potential safety hazard, the person skilled in art uses the open and close that the earthed switch operating axis comes limit switch cabinet door body usually.
At present, the switch cubicle that is used for the open and close of earthed switch operating axis limit switch cabinet body that occurs on market or the data, usually at the place, operating side of earthed switch operating axis locking part is set, extended support cooperates on the door body of locking part and switch cubicle or the door body, be typically provided with draw-in groove or the hole adaptive on the support with locking part, locking part rotates to the ground connection cutter when being in the position of separating brake with the earthed switch operating axis, make draw-in groove or hole on locking part and the support constitute clamping, this moment, the earthed switch operating axis can't rotate, and switch cubicle door body also just can't be opened; When the earthed switch operating axis rotated to ground state, draw-in groove on locking part and the support or hole broke away from, and switch cubicle door body just can be opened.
In technique scheme, if the drive motors of control earthed switch operating axis or manually executive item is firmly excessive, draw-in groove or hole on the support that extends on the locking part that can cause place, earthed switch operating axis operating side and switch cubicle door body or the door body take place to break away from or breakage; And the quality of fit of locking part and earthed switch operating axis and support is had relatively high expectations, when locking part falls in draw-in groove on the support or the hole, slightly skew takes place and may cause locking part to enter in draw-in groove on the support or the hole back by card is firm fully in its position, locking part can't break away from from draw-in groove or hole, makes also can't implement when switch cubicle door body need be opened to open.
The utility model content
At the deficiency that prior art exists, the utility model provides a kind of compact conformation, the accurate positioning of earthed switch operating axis, has prevented the excessive interlocking device for earthing switch operation of switch cabinet that causes the displacement of earthed switch operating axis and improve security performance of operating force.
