The utility model also discloses the AC high-voltage line high-voltage isolating switch having the insulating support body as a component. By means of the technical scheme, the assembling fittings are reduced. The fastening installing structure is simplified. Products are rapid, timesaving and laborsaving to assemble, install and adjust. The using reliability is significantly enhanced.
Description
Technical field
Patent application of the present invention relates to the high-voltage switch electric appliance on ac high-voltage power line road, in particular the high voltage isolator of ac high-voltage circuit.
Background technology
High voltage isolator is a kind of device for switching product of connection in the ac high-voltage electric power electric wirings such as power plant, transformer station; its main-body structure is by base portion and the vertical two parallel insulation supporters that are fastened on base; the top of two insulation support bodies arranges and is assembled with the conductive switch part, and base is fixing being contained in high-tension electricity frame cross-arm or high-tension electricity cashier's office in a shop.Although the structure of this type of high voltage isolator product is simple, its disconnecting link is opened, closing operation, on high-voltage electric power circuit, form obvious visible cut-off point, but it is low that we find that the right angle consisted of two parallel insulation supporters and base in existing this type of switch support frame structure bears terminals mechanical load ability, power input line road and outlet line are continued tractive to two outsides by described support frame top, can cause base to be arc stress flexural deformation, this stress deformation also there will be at base fixing in filling improper operation, it has changed switch matching relationship good between disconnecting link and contact, cause the switch poor electric contact, even can cause electric power accident, another key technical problem that existing this type of high voltage isolator exists is: existing insulation support body insulation creep distance is undesirable, and in especially outdoor application, it resists the air-polluting ability, moreover be that this electrical equipment assembled configuration is comparatively complicated, the assembling product reliability is undesirable.
Summary of the invention
During the goal of the invention of patent application of the present invention is to install or in the line work connection, thoroughly avoid the influencing factor of the switch performance variation caused because of the base distortion, a kind of ac high-voltage circuit high voltage isolation switch insulating supporter and high voltage isolator are provided.
The ac high-voltage circuit high voltage isolation switch insulating supporter technical scheme that patent application of the present invention provides, its main technical content is: a kind of ac high-voltage circuit high voltage isolation switch insulating supporter, the insulation support body that the insulation branch one of dividing to both sides for insulation trunk and insulation trunk forms, two insulation branch tops are the end that arranges of switch module, and insulation trunk bottom face is fixedly end face of base.
Patent application of the present invention also provides a kind of ac high-voltage circuit high voltage isolator technical scheme that described insulation support body is member that includes, the insulation trunk bottom face of the insulation support body of this ac high-voltage circuit high voltage isolator is fixed in base, and two insulation branch tops arrange the switch assembling parts that is equipped with fixed contact fixed head and disconnecting link formation.
The disclosed ac high-voltage circuit of the present patent application high voltage isolation switch insulating supporter and high voltage isolator technical scheme, the one advantage is during product is fixed dress, both made the reasons such as fastening misoperation cause the base stress deformation, can not transmit again yet, affect to the switch assembling parts, electrically contact matching relationship and affect switch room; Its two advantage is to have improved the mechanical load ability of terminals, the traction force of both sides connection line only acts on the insulation support body that intensity is very high, eliminate the tractive metamorphosis to base, thoroughly avoided the switch poor electric contact at above 2, and the electric power accident caused thus.Its three advantage is that this insulation support body has extended the insulation creep distance between electrode and ground greatly, obviously improved the short circuit damage capability that the factors such as the anti-lightning of product and Chinese People's Anti-Japanese Military and Political College's gas pollution cause, reached the normal operation level in III level, IV level area, made that product has more by force, adaptive capacity widely; Its four advantage is that product design is more succinct, in integrally manufactured shaping, guaranteed namely that the switch that two of this insulation support body insulate between branchs coordinates distance, reduced the assembling accessory, simplified fastening mounting structure, assembling product, install and adjust be swift to operate, save time, laborsaving, greatly improved dependability.
The accompanying drawing explanation
Fig. 1～Fig. 4 includes this ac high-voltage circuit high voltage isolation switch insulating supporter V-type, U-shaped, T-shaped and four four kinds of high voltage isolator structural maps implementing structure of the type of falling A.
Embodiment
The disclosed ac high-voltage circuit of the present patent application high voltage isolation switch insulating supporter, the insulation support body 1 that insulation branch 11,12 one of dividing to both sides for insulation trunk 10 and insulation trunk 10 form, length and the thickness of trunk 10 and the insulation branch 11,12 of wherein insulating need be carried out adaptability design by the Practical Project requirement, and the surface of insulation support body 1 is provided with some full skirts.As shown in Figure 1 be V-type insulating supporting body structure, the symmetrical inclination of two insulation branchs 11,12, bottom are incorporated on central insulation trunk 10, reaching and surpassing under the prerequisite of insulation technology parameter, short and thick insulation trunk 10 can guarantee to fixedly mount intensity, the one compacting is obviously V-shaped, if because of requirement of engineering, can lengthen insulation trunk 10, the one compacting obviously is the Y type.The top of two insulation branchs 11,12 is the end that arranges of switch module, the fixed head 2,3 of pre-buried fixed contact on the horizontal end face on two tops, input terminal block 4 and output end wiring plate 5 fixedly are assemblied in respectively on fixed head 2,3, assemble, be combined with disconnecting link 6 between the two, the bottom face of insulation trunk 10 evenly is embedded with some nuts, by fastening bolt, be arranged on base 7 insulation support body 1 is fastening, form ac high-voltage circuit high voltage isolator.
