Abstract
The utility model discloses an oblique-pulling and hanging type lightning arrester for a 500KV power transmission line, which comprises a tower body used for erecting a high-voltage line and a metal oxide lightning arrester body with a composite housing, wherein the lightning arrester body is connected with the tower body through a connecting supporting rod in an articulated way, and is connected with a crank through a plurality of insulated pulling piece in a hanging way, a lower discharge electrode is arranged at the free end of the lightning arrester body, a chain insulator is hung at the extending end of the lightning arrester body, an upper discharge electrode is arranged at the lower end of the chain insulator, the positions of the upper discharge electrode and the lower discharge electrode correspond vertically and remain at a striking distance, the connecting supporting rod is in a two-section structure, the two sections of the connecting supporting rod are mutually and rigidly connected through an insulating piece, and a discharge counter is arranged on the connecting supporting rod. The lightning arrester has the advantages that the weight of the mounting connecting mechanism of the lightning arrester can be greatly reduced, the mechanical stress on the tower body can be reduced, the structure is simple, the weight is light, the mounting is convenient, and the lightning arrester is safe and reliable.
Description
Technical field
The utility model belongs to electrical equipment technical field, particularly a kind of 500KV transmission line hanging lightning arrester of tiltedly leaving behind.
Background technology
At the 500kV extra high voltage network polymeric metal oxide surge arrester is installed, for lightning protection provides a kind of novel and effective means.At present, the mounting structure of this lightning arrester has air gap or insulator to support two kinds in gap usually.The Transmission Line Arrestor of air gap adopts cross-arm to stretch out the mount scheme of suspension more, this mount scheme need the direction along lead be installed a platform on the cross-arm of tower body, cause thus tower body particularly cross-arm to bear mechanical stress very big, trouble not only is installed, high material consumption, and have bigger potential safety hazard.
The utility model content
The purpose of this utility model is to overcome defective of the prior art, and 500KV transmission line a kind of simple in structure, in light weight, easy for installation, the safe and reliable hanging lightning arrester of tiltedly leaving behind is provided.
Realize that the technical scheme that the purpose of this utility model adopted is: this device comprises tower body and the polymeric metal oxide surge arrester body that is used to set up high-tension line, wherein, lightning arrester body is articulated and connected by connecting pole and tower body, and by several the insulation tensile elements with described crank arm the suspension be connected, the free end of lightning arrester body is provided with down sparking electrode, external part be hung with insulator string, the lower end of insulator string is provided with sparking electrode, the position of last sparking electrode and following sparking electrode is corresponding up and down and maintain arcing distance, described connection pole is a two-stage structure, and be rigidly connected mutually by insulating part, be provided with discharge counter connecting on the pole.
The mixed structure that described insulation tensile elements can adopt composite rod insulator or composite rod insulator to be connected with pull bar.
The 500KV transmission line of making according to the such scheme hanging lightning arrester of tiltedly leaving behind can alleviate the weight that lightning arrester is installed bindiny mechanism greatly, reduces the mechanical stress that tower body bears.Advantages such as compared with prior art, this device has simple in structure, and is in light weight, easy for installation, safe and reliable.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Referring to Fig. 1,500KV transmission line of the present utility model this device of hanging lightning arrester of tiltedly leaving behind comprises tower body 1 and the polymeric metal oxide surge arrester body 5 that is used to set up high-tension line.Wherein, lightning arrester body 5 connects pole 6 by insulation and is articulated and connected with tower body 1, lightning arrester body 5 also hangs with tower body 1 by several insulation tensile elements 8,9,10 and is connected, and lightning arrester body 5 can be freely swung, and the free end of lightning arrester body 5 is connected with down sparking electrode 4.The insulation tensile elements 10 of lightning arrester body 5 free ends can adopt composite rod insulator, be positioned at the mixed structure that the insulation tensile elements 9 of lightning arrester body 5 middle parts can adopt composite rod insulator to be connected with pull bar, be positioned at lightning arrester body 5 and can adopt pull bar and insulating part syndeton with the insulation tensile elements 8 that is connected the pole middle part, so both can save the consumption of composite rod insulator, reduce cost, can guarantee the shielding between lightning arrester body 5 and the tower body 1 again.Described connection pole 6 is a two-stage structure, and is rigidly connected mutually by insulating part, so that guarantee the insulation between lightning arrester body 5 and the tower body 1.Be provided with discharge counter 7 connecting on the pole 6, the end of incoming cables of this discharge counter 7 be connected pole 6 connections, the leading-out terminal of discharge counter 7 is connected with earth cable, constitutes the grounded circuit of lightning arrester body 5 thus.The external part of described tower body 1 is hung with insulator string 2, and the lower end of insulator string 2 is connected with sparking electrode 3, and the position of last sparking electrode 3 and following sparking electrode 4 is corresponding up and down and maintain arcing distance by setting.
Claims (2)
