Abstract
The invention relates to an operation interlocking device of a cable room door and a grounding switch of a high-voltage switch cabinet. A crank arm of an operating shaft of the grounding switch is arranged in the upper part of a vertical column at one side of a cabinet body and is connected with a locking plate by a connecting plate; a locking hook at the lower end of the locking plate corresponds to a door locking pin on an inner side plate of a front door of a cable room; a limiting pin fixed on a bracket is inserted in an upper vertical-surface limiting groove of the connecting plate; the connecting plate and the locking plate are connected by a screw and a return spring; a door pressing plate is fixedly connected onto the back surface of the front door of the cable room; an installing frame is fixedly connected onto a front rail of the cabinet; a door-pressing-plate entering and exiting port of the installing frame is internally provided with a coupling plate; the upper end of the coupling plate is fixedly connected with a locking pin, and the lower end of the coupling plate is connected with a right-end baffle of the installing frame by a spring pin and a spring; and the front end of the locking pin corresponds to an operating port of the grounding switch. The operation interlocking device has the advantages that when the grounding switch is not switched on, the cable room door can not be opened, and after the grounding switch is switched on, the cable room door can be opened; after the cable door is opened, the operating port of the grounding switch is locked by the interlocking pin, and the grounding switch can not be operated; and after the cable room door is closed, the interlocking pin leaves from the operating port of the grounding switch, and then the grounding switch can be operated.
Description
Technical field
The present invention relates to a kind of power high voltage switch cubicle, especially a kind of cable chamber door of power high voltage switch cubicle and ground switch interlocking device.
Background technology
In the power high voltage switch cubicle; cable chamber door is the door that personnel enter maintenance work in switch cubicle; earthed switch is the equipment that guarantees maintenance personal's safety; namely to the conductor three-phase shortcircuit ground connection (earthed switch "on" position) of maintenance product; this moment as electric to the conductor misdelivery of maintenance product, the conductor of maintenance product is in the scope of low voltage safety because of short circuit grounding, and power supply is because of short-circuit protection action outage; but this moment, power-supply device was impacted, and therefore must prevent earthed switch "on" position misdelivery electricity.
If earthed switch is by the mistake separating brake, when electric to the conductor misdelivery of maintenance product, maintenance product is that full voltage jeopardizes personnel's life, therefore must after cable chamber door is opened, stop the earthed switch operation.
Cable chamber door can not opened so power high voltage switch cubicle, earthed switch close a floodgate; Cable chamber door is not closed, and stops the earthed switch operation, is the mandatory requirement that guarantees safety.
At develop new product (power high voltage switch cubicle), in market, the interlock of different cabinet types can not be general, needs the fully applicable novel interlock of new cabinet type design trial-production.
Summary of the invention
The present invention will provide a kind of high-tension switch cabinet cable chamber door and ground switch interlocking device, be power high voltage switch cubicle newly developed interlock for a cover cable door and earthed switch, when earthed switch is not closed a floodgate, cable chamber door can not be opened, and after earthed switch closes a floodgate, cable chamber door can be opened; After the cable door was opened, the earthed switch gathering hole was by the interlocking latch locking, can not the operational grounding switch, and after cable chamber door was closed, interlocking latch left the earthed switch gathering hole, and earthed switch can operate.
for achieving the above object, technical scheme of the present invention is: a kind of high-tension switch cabinet cable chamber door and ground switch interlocking device, comprise the Qianmen, cable vault, cabinet, grounding switch operating device, Qianmen, cable vault locking device, be characterized in: grounding switch operating device comprises earthed switch operating axis connecting lever, connecting plate, jam plate, support, slide plate, screw rod, back-moving spring, spacer pin, the door lock pin, earthed switch operating axis connecting lever is arranged in cabinet one heel post top, and be connected with jam plate by connecting plate, door lock pin on the corresponding cable vault of the latch hook of jam plate lower end Qianmen interior plate, be inserted with the spacer pin that is fixed on support on connecting plate in the facade stopper slot, be connected with back-moving spring by screw rod between connecting plate and jam plate, Qianmen, cable vault locking device comprises installing rack, yoke plate, lock pin, spring catch, spring, securing member, door pressing plate, the door pressing plate is fixedly connected on the back side, Qianmen, cable vault, installing rack is fixedly connected on before the cabinet of cabinet on shelves, is provided with the yoke plate to the pressing plate of answering the door in the door pressing plate of installing rack is imported and exported, and the yoke plate upper end is fixedly connected with the lock pin that is positioned at installing rack top, the lower end is connected with installing rack right-hand member baffle plate with spring by spring catch, the corresponding earthed switch gathering hole of lock pin front end.
When earthed switch closed a floodgate, the operating axis connecting lever drives jam plate by connecting plate latch hook separated release with the door lock pin.
When earthed switch was opened a sluice gate, the latch hook of connecting plate moving jam plate of shipper pole in the promotion of spring hooked the locking of door lock pin.
When the cable vault closed at the Qianmen, the door pressing plate inserted the door pressing plate of installing rack and imports and exports, the slope extruding yoke plate of door pressing plate, and yoke plate band pendulum lock pin withdraws from the earthed switch gathering hole.
When the cable vault opened at the Qianmen, the door pressing plate was imported and exported from the door pressing plate of installing rack and is withdrawed from, and yoke plate is with pendulum lock pin to insert the earthed switch gathering hole under spring action.
The invention has the beneficial effects as follows:
The invention provides two kinds of outlet cable chamber doors and ground switch interlocking device:
When earthed switch separated, the earthed switch operating axis was tended to act and is moved on plate, and the ground switch interlocking device slide plate is replied by spring and moved, and moved the lock pin that fastens cable chamber door on the latch hook of its slide plate lower end, and door can not be opened; When earthed switch closed a floodgate, the earthed switch operating axis plate of tending to act moved down, and the ground switch interlocking device slide plate moves down Compress Spring, moved away the lock pin of cable chamber door under the latch hook of its slide plate lower end, and door can be opened.
When cable chamber door was opened, the door clip plate left earthed switch gathering hole interlock (calling interlocking in the following text), and the lock pin of interlocking puts in the earthed switch gathering hole under the effect of spring, made the earthed switch operation tool can not inject its gathering hole and carried out the earthed switch operation; When cable chamber door is closed, the door clip plate injects earthed switch gathering hole interlock (calling interlocking in the following text), interlock is compressed by the extrusion spring of a pressing plate and drives the lock pin of interlocking to leave the earthed switch gathering hole, makes the earthed switch operation tool can inject its gathering hole and carries out the earthed switch operation.
Therefore, when the present invention can be grounded switch and do not close a floodgate, cable chamber door can not be opened, and after earthed switch closes a floodgate, cable chamber door can be opened; After the cable door was opened, the earthed switch gathering hole was by the interlocking latch locking, can not the operational grounding switch, and after cable chamber door was closed, interlocking latch left the earthed switch gathering hole, and earthed switch can operate.
