Follow in the conductor hole the even interval of length direction of SMC insulation board sets up, and each the conductor hole all is located on the axis of SMC insulation board. The utility model discloses wearing wall insulating barrier and adopting the SMC insulation board, compare with the epoxy plate, the SMC insulation board has stronger insulating nature and hydroscopicity, can reduce common case enclosed bus effectively and wear the flashover accident that wall insulating barrier department appears to guarantee unit safety, move reliably. Additionally, the low -voltage breaker buckle -releasing apparatus with the reinforced insulation of the utility model is simple in structure and convenient to install.
Description
Technical field
The utility model relates to electrical equipment technical field, is specifically related to a kind of wall isolation dividing plate for common case enclosed busbar.
Background technology
Case enclosed busbar is the important conductive component bearing electric power transfer altogether, it is made up of in a metal cabinet three-phase bus conductor closes, is widely used between below 100MW generator lead-out wire and main transformer low-pressure side or 75MW and the current delivery between above unit auxiliary transformer low-pressure side and high voltage distribution installation.The rated voltage of case enclosed busbar is usually at 6-10kV altogether, and rated current is usually at 1000-5000A.
The trend of case enclosed busbar is normally arranged to open air by indoor altogether.From the indoor wall needed to open air through factory building, the wall place of factory building is air river outlet, is easy to produce moisture.In addition, also due to fire prevention reason, the place through walls of case enclosed busbar all will take partition measure altogether.For solving the problem, normal employing is wall isolation dividing plate at present.
In prior art, wall isolation dividing plate all adopts epoxy plate material to make, epoxy plate material starts to widely use in China in the 60 to 70's of last century, it has good insulation property and mechanical strength, there is certain fire-resistant and heat-resisting ability, but its moisture resistance is poor, the very easily moisture absorption and cause the damage of electric component after aging.Therefore, in recent years, case enclosed busbar mostly appears at wall isolation dividing plate place at the flashover fault in various degree that a lot of power plant occurs altogether.Equipment fault causes have a strong impact on unit safety, reliably operation.
Utility model content
In order to solve the problems referred to above that prior art exists, the utility model provides a kind of wall isolation dividing plate for common case enclosed busbar being conducive to reducing common case enclosed busbar flashover fault.
For achieving the above object, the utility model takes following technical scheme: a kind of wall isolation dividing plate for common case enclosed busbar adopts SMC insulation board, and described SMC insulation board adopts rectangular slab or cross plate, and described SMC insulation board offers some conductor bores.
Further, described conductor bores is arranged along the length direction uniform intervals of described SMC insulation board, and each described conductor bores is all positioned on the axis of described SMC insulation board.
Further, described conductor bores adopts circular port or square opening.
Further, some screws are offered in the both sides of described rectangle SMC insulation board.
Further, the thickness of described SMC insulation board adopts 10mm ~ 15mm.
The utility model is owing to taking above technical scheme, it has the following advantages: the utility model wall isolation dividing plate adopts SMC insulation board, compared with epoxy plate, SMC insulation board has stronger insulating properties and water absorption, effectively can reduce the flashover fault that common case enclosed busbar occurs at wall isolation dividing plate place, thus ensure unit safety, reliably run.In addition, the utility model also has the advantages such as structure is simple, easy for installation.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the utility model for the wall isolation dividing plate of common case enclosed busbar;
Fig. 2 is the another kind of structural representation of the utility model for the wall isolation dividing plate of common case enclosed busbar.
In figure: 1, SMC insulation board; 2, conductor bores; 3, screw.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail.
As depicted in figs. 1 and 2, the utility model provides a kind of wall isolation dividing plate for common case enclosed busbar, and it adopts on SMC (SheetMoldingCompound, sheet molding compound) insulation board 1, SMC insulation board 1 and offers some conductor bores 2.SMC insulation board 1 can adopt rectangular slab or cross plate.Further, conductor bores 2 is arranged along the length direction uniform intervals of SMC insulation board 1, and each conductor bores 2 is all positioned on the axis of SMC insulation board 1.
As depicted in figs. 1 and 2, according to difform bus-bars conductor in common case enclosed busbar, conductor bores 2 adopts difform hole.When common case enclosed busbar median generatrix conductor adopts copper pipe or aluminium-alloy pipe, conductor bores 2 adopts circular port.When common case enclosed busbar median generatrix conductor adopts copper aluminium bus array, conductor bores 2 adopts square opening.When bus-bars conductor is copper aluminium bus array, in conductor bores 2, place arranges supporting wall bushing, copper aluminium bus array is successively through wall bushing and wall isolation dividing plate, by this mounting means, greatly can increase the insulation distance between three-phase conductor, thus effectively reduce the flashover fault being total to case enclosed busbar and occurring at wall isolation dividing plate place, ensure unit safety, reliably run.
As depicted in figs. 1 and 2, for ease of fixed installation, some screws 3 are offered in the both sides of rectangle SMC insulation board 1.
The wall isolation dividing plate that the utility model is used for case enclosed busbar altogether adopts SMC insulation board 1, SMC insulation board 1 compared with epoxy plate, and except intensity and bending resistance degree are a little less than except epoxy plate, the insulating properties of SMC insulation board 1 and water absorption are all far above epoxy plate.Consider from the electric property angle of wall isolation dividing plate, improve the insulation property of wall isolation dividing plate and the moisture absorption index reducing wall isolation dividing plate is very important.The intensity of wall isolation dividing plate can be improved by the thickness suitably increasing SMC insulation board 1.
In above-described embodiment, for improving the intensity of wall isolation dividing plate, the thickness of SMC insulation board 1 adopts 10mm ~ 15mm.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but any change is done in its shape or structure; every have identical with the application or akin technical scheme, all drops within protection range of the present utility model.
