Abstract
The utility model discloses a low voltage power distribution cabinet vertical busbar protection device, which comprises a protecting cover body which is arranged on a drawer cabinet, wherein a plurality of vertical busbars are arranged in the protecting cover body at intervals, an insulating cover plate is arranged on the top portion of the protecting cover body, a plurality of through holes which are matched with the vertical busbars are arranged on the insulating cover plate, and the vertical busbars pass through the through holes to be lead into an isolation cavity which is formed through the insulating cover plate and the protection cover body. The low voltage power distribution cabinet vertical busbar protection device is provided with the insulating cover plate on the protection cover body, and the vertical busbars are lead into the isolation cavity which is formed through the insulating cover plate and the protection cover body, thereby effectively preventing foreign bodies from falling into vertical busbar channels to cause short circuit accidents, reducing potential safety hazard during the maintenance and use process, and increasing safety.
Description
Technical field
The utility model relates to the power distribution cabinet technical field, relates in particular to a kind of low-voltage distribution cabinet vertical bus bar protector.
Background technology
Low-voltage distribution cabinet has the drawer type functional unit, and drawer is made of the functional part that comprises some mechanical components, can exactly drawer be positioned at connection with the interlocking of being connected, the position such as test, separates, shifts out by behaviour's handle.All there is corresponding sign each position on the plate in front, and is simple, directly perceived.When circuit breaker closes when explaining, forbid that by mechanical interlocks drawer moves, to guarantee the fail safe of operation.Each drawer unit is fully independent, fully isolation between drawer.
Only have drawout cubicle that the saying of vertical bus bar is just arranged, vertical bus bar adopts and places vertically, and its vertical bus is according to the summation of each branch current and fixed (ampacity of busbar must not less than the summation of each branch breaker rated current).The specification of MNS series low-voltage distribution cabinet standard vertical bus is 1000A, and namely each cabinet can provide 1000A with interior distribution load ability, and (such as needs 1600A) will adopt two vertical buses when exceeding 1000A, can accomplish 2000A.
Traditional low-voltage distribution cabinet all adopts guard shield is set outside vertical bus bar for the protection vertical bus bar, but the top of guard shield does not but have sealing, so just can't effectively avoid foreign matter to fall into and cause short circuit accident in the vertical bus bar passage, has certain potential safety hazard.
The utility model content
The purpose of this utility model is to provide a kind of low-voltage distribution cabinet vertical bus bar protector, and it can avoid foreign matter to fall into the vertical bus bar passage effectively, security reliability is high; Protect incomplete problem with the vertical bus bar that solves prior art mesolow power distribution cabinet.
For reaching this purpose, the utility model by the following technical solutions:
A kind of low-voltage distribution cabinet vertical bus bar protector, it comprises the guard shield body that is installed on the drawout cubicle, the interval is furnished with a plurality of vertical bus bars in the described guard shield body, wherein, the top of described guard shield body is provided with insulation cover plate, cooperate a plurality of through holes that offer of vertical bus bar on the described insulation cover plate, described vertical bus bar passes through hole and introduces in the isolated chambers that is formed by insulation cover plate and guard shield body.
Especially, described insulation cover plate is assemblied in the top of guard shield body by at least one mounting panel, described mounting panel is connected by two flangings and is " L " structure, and all offer through hole on two flangings of described mounting panel, corresponding to also offering screwed hole on guard shield body and the insulation cover plate, one of them flanging of described mounting panel is fixed on the guard shield body by hold-down screw, and another flanging is fixed on the insulation cover plate by hold-down screw.
Especially, the number that arranges of described mounting panel is two, and the interval is arranged.
Especially, the number that arranges of described vertical bus bar is three, and corresponding vertical bus bar is offered three through holes on insulation cover plate.
Especially, described through hole is shaped as strip and parallel even distribution.
The beneficial effects of the utility model are, compared with prior art described low-voltage distribution cabinet vertical bus bar protector has installed insulation cover plate additional on the guard shield body, vertical bus bar is introduced in the isolated chambers that is formed by insulation cover plate and guard shield body, thereby effectively avoided foreign matter to fall into the vertical bus bar passage and caused short circuit accident, reduce the potential safety hazard of safeguarding in the use procedure, improved fail safe.
Description of drawings
Fig. 1 is the structural representation of the low-voltage distribution cabinet vertical bus bar protector that provides of the utility model embodiment 1;
Fig. 2 is that the A of Fig. 1 is to view;
