The invention further discloses the alternate-current high-voltage line high voltage isolator comprising the insulating supporting body. According to the technical scheme, the number of assembling accessories is reduced, the fastening installation structure is simplified, assembling operation, installing operation and adjusting operation of a product are fast and saving in time and labor, and using reliability is greatly improved.

Description

Ac high-voltage circuit high voltage isolator insulation support body and high voltage isolator

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 two parallel insulation support bodies that vertically are fastened on the 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.Though the structure of this type of high voltage isolator product is simple, its disconnecting link is opened, closing operation, form obvious visible cut-off point at high-voltage electric power circuit, but it is low that we find that the right angle support frame structure that is made of two parallel insulation support bodies and base in existing this type of switch bears terminals mechanical load ability, power input line road and outlet line continue tractive by described support frame top to two outsides, can cause base to be arc stress flexural deformation, it is fixing adorning in the improper operation that this stress deformation also can appear at base, it has changed switch matching relationship good between disconnecting link and the 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 the especially outdoor application, it resists the air-polluting ability; Moreover be that this electrical equipment assembled configuration is comparatively complicated, product assembling reliability is undesirable.

Summary of the invention

Thoroughly avoid being out of shape because of base the influencing factor of the switch performance variation that causes during the goal of the invention of patent application of the present invention is to install or in the line work connection, a kind of ac high-voltage circuit high voltage isolator insulation support body and high voltage isolator are provided.

The ac high-voltage circuit high voltage isolator insulation support body technical scheme that patent application of the present invention provides, its major technique content is: a kind of ac high-voltage circuit high voltage isolator insulation support body, for the insulation support body that dried one constitutes is propped up in the insulation that insulation trunk and insulation trunk divide to both sides, a two insulation dried top 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 an insulation dried top arranges 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 isolator insulation support body and high voltage isolator technical scheme, the one advantage is during product is fixed dress, both made reasons such as fastening misoperation cause the base stress deformation, can not transmit again yet, influence to the switch assembling parts, electrically contact matching relationship and influence 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 very high insulation support body of intensity, eliminated the tractive metamorphosis to base, more than 2 thoroughly avoided the switch poor electric contact, and the electric power accident that causes thus.Its three advantage is that this insulation support body has prolonged the insulation creep distance between electrode and the ground greatly, obviously improved the short circuit damage capability that factors such as the anti-thunderbolt of product and Chinese People's Anti-Japanese Military and Political College's gas pollution cause, reached the operate as normal level in III level, IV level area, made product have stronger, adaptive capacity widely; Its four advantage is that product design is more succinct, guaranteed namely in the integrally manufactured shaping that the switch that two of this insulation support body insulate between Zhi Gan cooperates distance, reduced the assembling accessory, simplified fastening mounting structure, product assembling, install and adjust swift to operate, save time, laborsaving, improved dependability greatly.

Description of drawings

Fig. 1～Fig. 4 includes this ac high-voltage circuit high voltage isolator insulation support body V-type, U-shaped, T type 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 isolator insulation support body, for the insulation support body 1 that dried 11,12 one constitute is propped up in the insulation that insulation trunk 10 and insulation trunk 10 divide to both sides, wherein insulate trunk 10 and insulation done 11,12 length and thickness and needed come adaptability design by actual engine request, and the surface of insulation support body 1 is provided with some full skirts.As shown in Figure 1 be V-type insulation support body structure, two insulation dried 11,12 symmetry tilt, the bottom is incorporated on the insulation trunk 10 of central authorities, 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, then the one compacting obviously is the Y type.It is the end that arranges of switch module that 11,12 top is done in two insulation, the
