Abstract
The invention discloses an interlocking device of an earthed switch operating mechanism, comprising a rear door plate and an earthed switch operating mechanism. A hollow lock sleeve is movably sleeved at a position on which an operating shaft of the earthed switch operating mechanism is close to a rear door plate end; a spring is arranged between the hollow lock sleeve and an operating shaft end socket; a non-round stop platform is arranged at the periphery of the lock sleeve; and a stop hole matched with the stop platform is arranged on a cabinet frame at the rear door plate side. With the device provided by the invention, the situation that the earthed switch is opened when the rear door of a switch cabinet is not closed can be avoided, and the situation that personnel safety is threatened when a circuit breaker is switched on so as to electrify a cable chamber while the back door of the switch cabinet is opened is prevented; and in addition, the device provided by the invention has the characteristic of simple structure and is convenient in implementation.
Description
Technical field
The invention belongs to power transmission and distribution voltage switchgear field, especially relate to a kind of earthed switch operating mechanism interlock.
Background technology
Existing metal-clad moveable formula switchgear, its original earthed switch operating mechanism interlock is after earthed switch closes a floodgate, open at the back door, and the maintenance personal can overhaul components and parts in the cabinet, but the maintenance finish after, if forgetting, operating personnel shut the back door, earthed switch still can separating brake, thereby breaker closing send electricity, makes cable vault's compartment charged, this moment, the cable vault was opened wide, the safety that jeopardizes personnel.
Summary of the invention
The objective of the invention is to improve the deficiency of prior art and provide a kind of switch cubicle of avoiding not having to make the earthed switch separating brake under the situation of closing back door, can prevent that breaker closing when opening at the switch cubicle back door from making the cable vault charged and jeopardize personnel's safe, simple in structure, the earthed switch operating mechanism interlock being convenient to implement.
The object of the present invention is achieved like this, a kind of earthed switch operating mechanism interlock, form by Rear Door and earthed switch operating mechanism, be characterized near Rear Door end movable sleeve hollow lock tube being arranged at the operating axis of earthed switch operating mechanism, spring be installed in the hollow lock tube and the operating axis termination between, the lock tube periphery is provided with non-circular stop platform, and the cabinet body frame of Rear Door side is provided with the stop hole that cooperates with the stop platform.
Compared with the prior art the present invention has following distinguishing feature and good effect: the present invention increases the reverse interlocking with the back door on the basis of former earthed switch operating mechanism interlock, promptly the operating axis at the earthed switch operating mechanism has hollow lock tube near Rear Door end movable sleeve, spring be installed in the hollow lock tube and the operating axis termination between, the lock tube periphery is provided with non-circular stop platform, the cabinet body frame of Rear Door side is provided with the stop hole that cooperates with the stop platform, like this when the door open structure of back door, lock tube ejects outside cabinet under the effect of spring, the cabinet body frame that the non-circular stop platform of lock tube just in time enters the Rear Door side is provided with the stop hole that cooperates with the stop platform, the stop platform is blocked by stop hole, this moment, the earthed switch operation axis can not rotate, that is to say that earthed switch this moment can not separating brake, circuit breaker can not close a floodgate, send under the situation of having stopped to open at the back door, the situation that jeopardizes personal security takes place, and simple in structure, is convenient to implement.
Description of drawings
Below in conjunction with drawings and Examples the present invention is described in further details.
Fig. 1 is a kind of structural representation of the present invention.
Embodiment
Embodiment, a kind of earthed switch operating mechanism interlock, with reference to Fig. 1, form by Rear Door 1 and earthed switch operating mechanism 2, the structure and the prior art of earthed switch operating mechanism 2 are identical, operating axis 3 at earthed switch operating mechanism 2 has hollow lock tube 4 near Rear Door 1 end movable sleeve, spring 5 is installed in the hollow lock tube 4 and between operating axis 3 terminations, lock tube 4 peripheries are provided with non-circular stop platform 6, the cabinet body frame of Rear Door 1 side is provided with the stop hole 7 that cooperates with stop platform 6, and this has constituted a kind of structure of the present invention.
Claims (1)
