Abstract
The utility model discloses a front cabinet door structure of a low-voltage power distribution cabinet. The front cabinet door structure comprises a supporting mounting plate, a brow head which is placed above the supporting mounting plate and a ventilation door which is placed below the supporting mounting plate. One side of the supporting mounting plate is sequentially provided with an instrument door, a front upper door and a front lower door from top to bottom in a hinged mode. The supporting mounting plate is fixedly provided with a horizontal baffle I and a horizontal baffle II, wherein the baffle I is placed at a position between the instrument door and the front upper door, and the baffle II is placed at a position between the front upper door and the front lower door. The front cabinet door structure of the low-voltage power distribution cabinet can enable an outgoing line power distribution circuit to be debugged, operated and maintained conveniently.
Description
Technical field
The utility model relates to a kind of cabinet door structure for low-voltage distribution cabinet.
Background technology
The low voltage isolation switch of present many electrical equipment manufacturer production or fuse disconnecting switch, it is installed between the outer operating grip of GGD cabinet and the pitman shaft mechanical interlocking, after isolating switch is closed a floodgate, the operating grip that cabinet is outer and pitman shaft interlocking are at first phase, whole foregate can not be opened, so that each shunt breaker of plastic casing of isolating switch or fuse disconnecting switch below can not operate separately and overhaul, must make isolating switch or fuse disconnecting switch separating brake if open the door, behind its separating brake, all transmission line circuits all can have a power failure in this cabinet, institute's carrying device of each distribution loop all can be out of service, and impact is normal produces or life.
Summary of the invention
The problems referred to above that exist in order to solve existing cabinet door, the utility model provides a kind of front door of low-voltage distribution cabinet, its technical scheme of taking is: this structure comprises support mounting plate, be positioned at the brows of support mounting plate top, and the air door that is positioned at the support mounting plate below, one side of support mounting plate is hinged with instrument door from top to bottom successively, front calling and front Xiamen, be fixed with respectively horizontal baffle plate I and baffle plate II on the support mounting plate, wherein baffle plate I is in the position between instrument door and front the calling, baffle plate II is in the position between to the doorstep front and the front Xiamen, front to the doorstep upper fitting operation handle and door lock I install door lock II on the front Xiamen.
The utility model is fanned the gate with the foregate of low-voltage distribution cabinet by 1 of original standard scheme and is changed up and down two doors into, conveniently the outlet distribution loop is debugged, is operated and keeps in repair.Before the upper operating grip that isolating switch or fuse disconnecting switch are installed to the doorstep, the manual switch operating grip can make isolating switch close a floodgate, and by the interlocking of pitman shaft and handle, can not open to the doorstep before making after closing a floodgate, and just can open after only having separating brake.Front lower door pins by door lock, open front Xiamen by key, can carry out manual operation or maintenance to each transmission line circuit, and with cabinet in relative isolation of isolating switch of top, solved original 1 fan foregate and can not open the problem that door can not operate and overhaul transmission line circuit because of isolating switch after closing a floodgate.
Description of drawings
Fig. 1 is the structural representation of the utility model when opening the door.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Shown in Fig. 1, brows 1 are positioned at support mounting plate 3 tops, air door 4 is positioned at support mounting plate 3 belows, one side of support mounting plate 3 is hinged with instrument door 2, front to the doorstep 5 and front Xiamen 7 from top to bottom successively, be fixed with respectively horizontal baffle plate I6 and baffle plate II9 on the support mounting plate 3, wherein baffle plate I6 is in instrument door 2 and the front to the doorstep position between 5, before baffle plate II9 is in to the doorstep 5 and front Xiamen 7 between the position, before to the doorstep fitting operation handle 10 and door lock I8 on 5, on the front Xiamen 7 door lock II11 only is installed.
