Abstract
The invention discloses a kind of vertical busbar protective device for low voltage switch box, it comprises the guard shield body be installed on drawout cubicle, in described guard shield body, interval is furnished with multiple vertical bus bar, the top of described guard shield body is provided with insulation cover plate, what described insulation cover plate coordinates vertical bus bar offers multiple through hole, and described vertical bus bar is introduced in the isolated chambers that formed by insulation cover plate and guard shield body through through hole.Above-mentioned vertical busbar protective device for low voltage switch box has installed insulation cover plate additional on guard shield body, vertical bus bar is introduced in the isolated chambers formed by insulation cover plate and guard shield body, thus effectively prevent foreign matter and fall into vertical bus bar passage and cause short circuit accident, reduce the potential safety hazard safeguarded in use procedure, improve fail safe.
Description
Technical field
The present invention relates to power distribution cabinet technical field, particularly relate to a kind of vertical busbar protective device for low voltage switch box.
Background technology
Low-voltage distribution cabinet has drawer type functional unit, and drawer is made up of the functional part comprising some mechanical components, can be positioned at by drawer to be exactly connected, to test, to be separated, the position such as to shift out by behaviour's handle and interlocking greatly.All there is corresponding mark each position on front panel, simple, directly perceived.When circuit breaker conjunction is explained, forbid that drawer moves by mechanical interlocks, to ensure the fail safe operated.Each drawer unit is completely independent, completely isolated between drawer.
Only have drawout cubicle just to have the saying of vertical bus bar, vertical bus bar adopts and places vertically, and its vertical bus is summation according to each branch current and fixed (ampacity of busbar must not be 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 the distribution load ability within 1000A, and when exceeding 1000A, (as needs 1600A) will adopt two vertical bus, can accomplish 2000A.
Traditional low-voltage distribution cabinet is protection vertical bus bar, all adopt and arrange guard shield outside vertical bus bar, but the top of guard shield is not but closed, foreign matter so just effectively cannot be avoided to fall in vertical bus bar passage and cause short circuit accident, there is certain potential safety hazard.
Summary of the invention
The object of the present invention is to provide a kind of vertical busbar protective device for low voltage switch box, it can be avoided effectively, and foreign matter falls into vertical bus bar passage, security reliability is high; Incomplete problem is protected with the vertical bus bar solving prior art mesolow power distribution cabinet.
For reaching this object, the present invention by the following technical solutions:
A kind of vertical busbar protective device for low voltage switch box, it comprises the guard shield body be installed on drawout cubicle, in described guard shield body, interval is furnished with multiple vertical bus bar, wherein, the top of described guard shield body is provided with insulation cover plate, what described insulation cover plate coordinates vertical bus bar offers multiple through hole, and described vertical bus bar is introduced in the isolated chambers that formed by insulation cover plate and guard shield body through through hole.
Especially, described insulation cover plate is assemblied in the top of guard shield body by least one mounting panel, described mounting panel connects in " L " structure by two flangings, and two of described mounting panel flangings all offer through hole, also screwed hole is offered corresponding on guard shield body and insulation cover plate, one of them flanging of described mounting panel is fixed on guard shield body by hold-down screw, and another flanging is fixed on insulation cover plate by hold-down screw.
Especially, the number that arranges of described mounting panel is two, and interval is arranged.
Especially, the number that arranges of described vertical bus bar is three, and corresponding vertical bus bar offers three through holes on insulation cover plate.
Especially, the shape of described through hole is strip, and is parallelly uniformly distributed.
Beneficial effect of the present invention is, compared with prior art described vertical busbar protective device for low voltage switch box has installed insulation cover plate additional on guard shield body, vertical bus bar is introduced in the isolated chambers formed by insulation cover plate and guard shield body, thus effectively prevent foreign matter and fall into vertical bus bar passage and cause short circuit accident, reduce the potential safety hazard safeguarded in use procedure, improve fail safe.
Accompanying drawing explanation
Fig. 1 is the structural representation of the vertical busbar protective device for low voltage switch box that the specific embodiment of the invention 1 provides;
Fig. 2 is the A direction view of Fig. 1;
Fig. 3 is the B direction view of Fig. 1.
Embodiment
Technical scheme of the present invention is further illustrated by embodiment below in conjunction with accompanying drawing.
Refer to shown in Fig. 1 to Fig. 3, in the present embodiment, a kind of vertical busbar protective device for low voltage switch box comprises the guard shield body 2 be installed on drawout cubicle 1, in described guard shield body 2, interval is furnished with three vertical bus bars 3, the top of described guard shield body 2 is provided with insulation cover plate 4, described insulation cover plate 4 coordinates the strip through hole 5 offering three parallel interval distributions of vertical bus bar 3, described vertical bus bar 3 is introduced in the isolated chambers that formed by insulation cover plate 4 and guard shield body 1 through through hole 5, thus effectively prevent foreign matter and fall into vertical bus bar passage and cause short circuit accident.
Described insulation cover plate 4 is assemblied in the top of guard shield body 2 by two spaced apart mounting panels 6, described mounting panel 6 connects in " L " structure by two flangings, and two flangings of described mounting panel 6 all offer through hole, also screwed hole is offered corresponding on guard shield body 2 and insulation cover plate 4, one of them flanging of described mounting panel 6 is fixed on guard shield body 2 by hold-down screw 7, and another flanging is fixed on insulation cover plate 4 by hold-down screw 7.
Above embodiment has just set forth general principle of the present invention and characteristic; the present invention does not limit by above-mentioned example; without departing from the spirit and scope of the present invention, the present invention also has various change and change, and these changes and change all fall in the claimed scope of the invention.Application claims protection range is defined by appending claims and equivalent thereof.
