Abstract
Disclosed is a novel capacitive insulated switch cabinet main bus, comprising a guide body and capacitive insulators. The capacitive insulators are coated outside the guide body that is in a tubular shape. Flat type connecting sections are formed on the guide body by pressing at an interval; and there are no capacitive insulators on the flat type connecting sections. Each of the flat type connecting sections has two parallel surfaces and there is a gap between the two parallel surfaces of the connecting section; and parallel surfaces of the plurality of flat type connecting sections are parallel to each other. Two ends of capacitance plates inside the capacitive insulators are gradually shortened from inside to outside according to reasonable stepped differences; the innermost one of the capacitance plates is equipotential with the guide body and the outermost one of the capacitance plates is connected with a ground lead and is connected with a ground potential through the ground lead. Because the guide body is in the tubular shape, a current skin effect is effectively reduced and the current-carrying capacity is improved; moreover, the main bus can employ a fixed holding support and the supporting structure is simple.
Description
Technical field

Background technology
At present, the main bus bar in the switch cubicle that uses in the electric power system mainly with row's shape baffle, supports with insulator, needs the suit insulating sleeve during through cabinet.
Yet above-mentioned switch cubicle main bus bar has caused its ampacity low because of kelvin effect, and insulation supporting way complicated problems is arranged.
Summary of the invention
The present invention provides that a kind of ampacity is big, the simple novel capacitor type of insulating supporting structure insulated switch cabinet main bus bar.
For realizing above-mentioned purpose, the present invention provides a kind of novel capacitor type insulated switch cabinet main bus bar, comprises baffle, capacitor type insulating body, and this baffle is coated with said capacitor type insulating body, and said baffle in a tubular form.
Preferably, said baffle whenever has been pressed into flat-shaped connecting portion at a distance from one section, does not have said capacitor type insulating body on this flat-shaped connecting portion.
Preferably, said flat-shaped connecting portion has two parallel surfaces, has the gap between two parallel surfaces of this flat-shaped connecting portion, and the parallel surface of said some flat-shaped connecting portions is parallel mutually.
Preferably, the outermost of the capacitance plate of said capacitor type insulating body screen is connected with ground lead.
Preferably, progressively shorten according to rational ladder difference from inside to outside at the two ends of the capacitance plate of said capacitor type insulating body.
Preferably, there is oversheath the outside of said capacitor type insulating body.
The beneficial effect of novel capacitor type insulated switch cabinet main bus bar of the present invention: because baffle in a tubular form, reduces until the generation of avoiding the electric current kelvin effect effectively, improved ampacity, and this main bus bar can adopt the fixing tool of embracing to support, supporting construction is simple.

Embodiment
By specifying technology contents of the present invention, structural feature, realized purpose and effect, give explanation below in conjunction with execution mode and conjunction with figs. are detailed.
Please with reference to Fig. 1; Novel capacitor type insulated switch cabinet main bus bar of the present invention comprises baffle 10, capacitor type insulating body 20 and outer family cover 30; This baffle 10 is coated with said capacitor type insulating body 20, and there is said outer family cover 30 said capacitor type insulating body 20 outsides, and said baffle 10 in a tubular form.
The novel insulated switch cabinet of the present invention main bus bar during fabrication; According to switch cubicle length and branch row relative dimensions; Baffle 10 whenever has been pressed into flat-shaped connecting portion 11 at a distance from one section; Do not have said capacitor type insulating body 20 on this flat-shaped connecting portion 11, flat-shaped connecting portion 11 has two parallel surfaces, and the parallel surface of some flat-shaped connecting portions 11 is parallel mutually.The limit, two ends of flat-shaped connecting portion 11 is machined away; Make two parallel surface inwall places of flat-shaped connecting portion 11 have the certain clearance (not shown); This gap can with branch row thickness tight fit; On every section baffle 10, make capacitor type insulating body 20; Progressively shorten according to rational ladder difference from inside to outside at capacitor type insulating body 20 inner capacitance plate two ends, the interior screen and baffle 10 equipotentials of the capacitance plate of capacitor type insulating body 20, and the outermost screen of capacitance plate is connected with ground lead 40 and passes through ground lead 40 and is connected with earth potential.
Please with reference to Fig. 2, the novel insulated switch cabinet of the present invention main bus bar can be used as each phase capacitor type insulating main bus bar in use.With A1 phase capacitor type insulating main bus bar 61 and A2 mutually capacitor type insulating main bus bar 62 usefulness bus connecting plates 50 connect and compose A phase bus.With B1 phase capacitor type insulating main bus bar 71 and B2 mutually capacitor type insulating main bus bar 72 usefulness bus connecting plates 50 connect and compose B phase bus.With C1 phase capacitor type insulating main bus bar 81 and C2 mutually capacitor type insulating main bus bar 82 usefulness bus connecting plates 50 connect and compose C phase bus.A phase bus, B phase bus, C phase bus are arranged in parallel, and keep a determining deviation, are fixed on the top of switch cubicle with fixing armful tool 90.In each switch cubicle, the flat-shaped connecting portion 11 palpus interlaced arrangement of each phase bus are arranged with the convenient water conservancy diversion that connects.When flat-shaped connecting portion 11 was connected with water conservancy diversion row, water conservancy diversion was arranged in the gap that can insert flat-shaped connecting portion 11 and is electrically connected with novel capacitor type insulation main bus bar of the present invention formation.
In sum, novel capacitor type insulation main bus bar of the present invention has improved ampacity because baffle 10 in a tubular form, reduces the electric current kelvin effect effectively, and this main bus bar can adopt the fixing tool 90 of embracing to support, and supporting construction is simple.
The present invention is not limited to above-mentioned embodiment, and those skilled in the art that also can make multiple variation in view of the above, but any and the present invention are equal to or similar variation all should be encompassed in the scope of claim of the present invention.
