Abstract
The utility model discloses an interlocking mechanism of switchgear. The interlocking mechanism comprises a cabinet of the switchgear, and an operation shaft which is used for controlling a branch breaker and an isolation switch, wherein the cabinet is provided with a rear door, a pressing block is disposed at a rear surface of the rear door, a limiting groove is opened in a side frame of the cabinet opposite to the pressing block, a linkage sliding block used for pushing the operation shaft to move is disposed at a part which corresponds to the limiting groove, a position limiting block is disposed at an end of the linkage sliding block, the limiting block is capable of sliding into the limiting groove of the side frame of the cabinet, the linkage sliding block is provided with a chamber, a reset spring is disposed in the chamber of the linkage sliding block, the reset spring is connected with a guiding rod, and the guiding rod is used for controlling the branch breaker to be fixedly connected with the isolation switch. The interlocking mechanism is beneficial in that: when a branch breaker of a switch device is at a closed position with the isolation switch, the linkage sliding block is driven to rotate by the operation shaft, so as to allow the limiting block to stretch out of the limiting groove of the side frame of the cabinet, thus the cabinet door can be held in a certain place, and therefore the rear door can not be opened, so that an operator is prevented from entering into an electriferous room; and when the rear door of the switch device is opened for maintenance operation, the limiting block on the linkage block stretches into the limiting groove under the action of the pressing block and the spring, thus the linkage sliding block is prevented from rotating in an axial direction, only when the rear door of the switch is closed and pressed tightly, the operation shaft for controlling the branch breaker and the isolation switch is allowed to operate, so that an interlocking requirement of power on and off of the switch device is fulfilled.
Description
Technical field
The utility model relates to switch cabinet structure, especially a kind of interlocking mechanism of switch cabinet.
Background technology
Switch cubicle has the advantages such as volume is little, easy to operate, but due to after initial design switchgear for the fixed head of screw installation, for preventing that personnel from touching charged position, under charged condition, do not allow to open.The easy mistakenly entering charged chamber of operation personnel when actual inspection and maintenance, may cause personal injury, do not reach five anti-requirements of high voltage switchgear, during maintenance, the dismounting of mounting panel is inconvenient, if back door is set on switch cubicle, just must guarantee under power-off door opening state, for controlling the operating axis of minute circuit breaker and isolation switch, can not rotate, under power transmission is closed the door state, could rotating operation axle.
Summary of the invention
In order to address the above problem, the utility model provides a kind of interlocking mechanism of switch cabinet.
A kind of interlocking mechanism of switch cabinet, the cabinet that comprises switch cubicle, for controlling the operating axis of minute circuit breaker and isolation switch, cabinet is provided with back door, the back side at back door is provided with briquetting, in the cabinet side frame of briquetting opposite, have stopper slot, the position of matching with it at stopper slot place is provided with the catenating slider moving for promoting operating axis, one end of catenating slider is provided with guide vane end stop, guide vane end stop can slip in the stopper slot of cabinet side frame, catenating slider has cavity, in the cavity of catenating slider, be provided with back-moving spring, back-moving spring connects guide rod, guide rod with for controlling the operating axis of minute circuit breaker and isolation switch, be fixedly connected with.
Further, one end that described catenating slider is provided with guide vane end stop has circular protuberance.
Further, the outside of described operating axis is provided with supporting seat, described supporting seat encircling operation axle setting and being fixed on cabinet, and described operating axis can rotate vertically.
The beneficial effects of the utility model are: the isolating switch of switchgear is when closing position, by operating axis, drive catenating slider to rotate, guide vane end stop is shifted out outside cabinet side frame stopper slot, thereby hold cabinet door, realize minute circuit breaker and isolation switch when closing a floodgate, the back door of equipment can not be opened, and avoids between operating personnel's mistakenly entering into charged; Open while carrying out inspection operation at the back door of switchgear, effect due to briquetting and spring, guide vane end stop on catenating slider extend in stopper slot, catenating slider can not axial rotation, only have the cabinet door of switchgear to shut after compression, for controlling the operating axis of minute circuit breaker and isolation switch, just can operate, thus the chain requirement of assurance switchgear transmission or not.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of interlocking mechanism of switch cabinet
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Referring to Fig. 1, a kind of interlocking mechanism of switch cabinet, the cabinet 4 that comprises switch cubicle, for controlling the operating axis 3 of minute circuit breaker and isolation switch, cabinet 4 is provided with back door, the back side at back door is provided with briquetting 1, in briquetting 1 opposite cabinet 4 side frames, have stopper slot, the position of matching with it at stopper slot place is provided with the catenating slider 2 moving for promoting operating axis 3, one end of catenating slider 2 is provided with guide vane end stop 23, guide vane end stop 23 can slip in the stopper slot of cabinet 4 side frames, catenating slider 2 has cavity, in cavity, be provided with back-moving spring 22, back-moving spring 22 connects guide rod 21, guide rod 21 with for controlling the operating axis 3 of minute circuit breaker and isolation switch, be fixedly connected with.
One end that catenating slider 2 is provided with guide vane end stop 23 has circular protuberance 24.
The outside of operating axis 3 is provided with supporting seat 31, and supporting seat 31 encircling operation axles 3 arrange and are fixed on cabinet 4, and operating axis 3 can rotate vertically.
When back door is closed, the briquetting 1 of being located at the back side, back door promotes catenating slider 2 and moves, the guide vane end stop 23 of being located at catenating slider 2 one end removes stopper slot, rotate for controlling the operating axis 3 of minute circuit breaker and isolation switch and carry out closing operation, in the time of rotation, operating axis 3 rotates and drives catenating slider 2 to rotate, and catenating slider 2 drives guide vane end stop 23 to rotate, guide vane end stop 23 inserts and is fixed in the back-up ring on cabinet 4 back doors, thereby pulling back door, minute circuit breaker and isolation switch, under "on" position, can not open the door.
When open at back door, rotate for controlling the operating axis 3 of minute circuit breaker and isolation switch and carry out opening operation, in the back-up ring that guide vane end stop 23 inserts from cabinet 4 back doors, remove, when open at back door, the briquetting 1 at the back side, back door leaves the protuberance 24 of catenating slider 2, back-moving spring 22 resets, the guide vane end stop 23 that catenating slider 2 one end are provided with slips in the stopper slot of cabinet 4 side frames, due to catenating slider 2 with for controlling the operating axis 3 of minute circuit breaker and isolation switch, be fixedly connected with, slipping into guide vane end stop 23 in cabinet 4 side frame stopper slots has limited operating axis 3 and has rotated vertically, the closing operation that can not divide circuit breaker and isolation switch, guarantee maintainer's safety.
