Abstract
The invention relates to a manufacturing technique of electric equipments, in particular to a hard busbar insulation method of a high-tension switch cabinet, which is mainly characterized in that segmented heat releasing vents are arranged on the external insulating layer of the internal layer of a layer relative to combined installation of two sheets of hard busbars, or the segmented heat releasing vents are arranged on the internal layer of the external hard busbars of combined installation of a plurality of sheets of hard busbars and the relative external insulating layer of the hard busbars clamped in a plurality of sheets of hard busbars; the heat releasing vents are arranged in a staggered mode. The invention has the positive effects that the electric heat generated in the operation course of the hard busbars can be dissipated from the heat releasing vents through a narrow lane to obviously reduce the temperature rise of the hard busbars because the internal side of the hard busbars is provided with the heat releasing vents; the insulating property around the hard busbars is not influenced and can meet the requirements of voltage class standards because the heat releasing vents are internal openings; the manufacturing technique of the invention is suitable for the high-tension switch cabinet with large current, limited space in the cabinet and more than two sheets of external insulating layer hard busbars and can meet the miniaturization requirements of a high-tension complete switch cabinet.
Description
[technical field]
The present invention relates to electrical equipment manufacturing technology field, specifically, is the method for the hard bus insulation of a kind of high-tension switch cabinet.
[background technology]
High-tension switch cabinet is a staple product in the power transmission and transforming equipment, has important effect in the process of electric power transmission, distribution, electric energy conversion.High-tension switch cabinet mainly is made up of cabinet, electric elements (comprising insulating part), various mechanism, secondary terminal and line etc., has functions such as built on stilts turnover line, cable turnover line, bus contact.
Along with the needs in market, the high pressure voltage switchgear begins miniaturization.But this direct result of bringing is that the spacing of exposed bus air-safety is not enough in the switch cubicle, therefore, bus exposed in the cabinet is carried out the outsourcing insulation.The harmful effect that this outsourcing insulation causes is, causes the radiating effect of bus bad, more than every phase double-bus and the temperature rise index of the high pressure voltage switchgear median generatrix of dress all exceed standard.Therefore, must find a kind of method, can make the insulation standard of bus meet the requirement of electric pressure standard, can make bus keep better heat radiating effect again,
[summary of the invention]
The objective of the invention is to overcome the deficiencies in the prior art, the requirement that a kind of insulation standard that can make bus meets the electric pressure standard is proposed, can make bus keep the hard bus insulation method of high-tension switch cabinet of better heat radiating effect again, the road of high pressure voltage switchgear miniaturization can successfully be gone on.
For achieving the above object, the technical scheme taked of the present invention is:
The hard bus insulation method of a kind of high-tension switch cabinet, it is characterized in that, on the outsourcing insulation of opposite layer (internal layer) of two hard buses and dress, offer the thermovent of segmentation, or at the internal layer of the hard bus in outside of hard bus of multi-disc and dress and be clipped in the thermovent of offering segmentation on the outsourcing insulation of opposite layer of hard bus of the inside.
Described thermovent is at the opposite layer of two or the hard bus of multi-disc and dress or be clipped in the setting of staggering on the outsourcing insulation of hard bus of the inside.
The good effect of the hard bus insulation method of a kind of high-tension switch cabinet of the present invention is:
(1) is inner opening owing to what offer, do not influence hard bus insulation property on every side, make hard bus insulating properties on every side still can meet the requirement of electric pressure standard;
(2) owing to be the thermovent of offering many places at the medial surface of hard bus, the electric heating that hard bus is in operation can shed through the passageway mouth from thermovent, and the electric heating that therefore can reduce hard bus can obviously reduce the temperature rise of hard bus to the conduction of busbar joint place;
(3) it is limited to be specially adapted in the big electric current, cabinet the space, is provided with the high-tension switch cabinet of two hard buses of above outsourcing insulation, can satisfy the requirement of high pressure voltage switchgear miniaturization.

[embodiment]
Provide the embodiment of the hard bus insulation method of a kind of high-tension switch cabinet of the present invention below in conjunction with accompanying drawing, be provided at three and adorn the embodiment of offering thermovent on the outsourcing insulation of hard bus.
Referring to accompanying drawing 1.
At three and adorn the specific practice of offering thermovent on the outsourcing insulation of hard bus and be: with three and adorn hard bus and be divided into three and adorn first 1 of hard bus, three and adorn second 2 of hard bus and three and adorn the 3rd 3 of hard bus; The outsourcing insulation 4 of parcel on it is divided into 4 cross sections: the A-A cross section; The B-B cross section; C-C cross section and D-D cross section.
The A-A cross section is three and adorns the inner face of first 1 of hard bus, and the thermovent of offering on its outsourcing insulation 4 is a thermovent that begin from the top, that constant spacing is arranged, and promptly hard the 1st inner face thermovent 5 of bus is referring to accompanying drawing 2.
The B-B cross section is three and adorns second 2 of hard bus and three and adorn the corresponding surface of first 1 inner face of hard bus, belong to inner face, the thermovent of offering on its outsourcing insulation 4 is empty thermovent position thermovent that begin, that constant spacing is arranged from the top, be second inner face thermovent 6 of hard bus, referring to accompanying drawing 3.
The C-C cross section is three and adorns second 2 of hard bus and three and adorn the corresponding surface of the 3rd 3 inner faces of hard bus, also belongs to inner face, offers the mode of the mode of thermovent with the B-B cross section on its outsourcing insulation 4, referring to accompanying drawing 4.
The D-D cross section is three and adorns the inner face of the 3rd 3 of hard bus, and the mode of the thermovent of offering on its outsourcing insulation 4 is with the mode in A-A cross section, and the 3rd inner face thermovent 7 of the hard bus that promptly begins from the top, constant spacing is arranged is referring to accompanying drawing 5.
Three and adorn first 1 of hard bus and three and adorn and be not open thermovent on the outside of the 3rd 3 of hard bus, cover by outsourcing insulation 4, thereby do not influence insulation property around the hard bus.
The above only is a preferred implementation of the present invention.Should be pointed out that those skilled in the art without departing from the inventive concept of the premise, can also make some improvements and modifications, still, these improvements and modifications also should be considered as protection scope of the present invention.
