Abstract
A silicone rubber zinc-oxide arrester of needle type pertains to power equipment, which consists of an insulator, a core, a conductor and an installation body. A core fastener is pyrocondensation polyethylene pipe which wraps outside of the core body; one end of the pipe is fixedly connected with the conductor, while the other end of the pipe is fixedly connected with the installation body; the core fastener is installed in the silicon rubber insulator and is integrated with the silicon rubber insulator, the core, the conductor and the installation body. The utility model has the advantages of easy process, extensive usage, good performance of insulating and lightning protection, thus greatly enhancing the insulation level and decreasing the current leakage.
Description
Technical field
The utility model relates to a kind of pin type silicon rubber zinc oxide arrester, belongs to the electric power system high voltage electric equipment.
Background technology
In electric power system, the thunder resisting equipment that is used for 6-10KV circuit network and transformer platform district, be valve type arrester and silicon rubber zinc oxide arrester, particularly in the design that becomes platform installation atlas on the post, all adopt three pin insulators to cooperate installation with three lightning arresters, its weak point is production cost height, maintenance rate height.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, will become that three transition combine with pin insulator and three lightning arresters on the platform and provide a kind of, possesses the supporting role of pin insulator, possesses the lightning protection effect of lightning arrester again.Adopting the thermal polycondensation ethylene tube is the pin type silicon rubber zinc oxide arrester that securing member is fixedlyed connected with fixture, electric-conductor pyrocondensation.
The purpose of this utility model is achieved in that the core body securing member is that a thermal polycondensation ethylene tube is positioned at the silicon rubber insulation body, be coated on outside the core body, its end is fixedlyed connected with electric conductor, the other end is fixedlyed connected with fixing body, connect as one with silicon rubber insulation body, core body, electric conductor, fixing body, wherein the top of the bottom of electric conductor, fixing body is respectively equipped with an enclosed slot.
Compared to existing technology, each change platform of the utility model is all saved three pin insulators, can save 216 yuan of installation costs.Its good insulation preformance can greatly improve the insulation level of electrical network, reduces leakage current, also has anti-outside destroy ability simultaneously, avoids safeguarding.Its anti-twist intensity reaches standard-required, the entire equipment handling ease, and raw material are easily purchased, and technology is simple.On being used for post, become the platform, also can be used for on-pole switch, the supporting use of capacitor, also can be used for the circuit transition and support the lightning protection of holding concurrently.The utility model is convenient to install and use, and market prospects are good.
Description of drawings
Accompanying drawing is the utility model structural representation.
Embodiment
The utility model such as accompanying drawing are made up of silicon rubber insulation body 4, core body 5, electric conductor 1, fixing body 7, and core body 5 adopts five zinc oxide valve plates, and rated voltage is by national standard 17KV, continuous operating voltage 13.6KV configuration.Core body securing member 2 is thermal polycondensation ethylene tubes of an internal diameter 33mm, wall thickness 2.5mm, it is coated on the outside of core body 5, its end is fixedlyed connected with electric conductor 1 pyrocondensation, the other end is fixedlyed connected with fixing body 7 pyrocondensations, core body securing member 2 is positioned at silicon rubber insulation body 4, silicon rubber insulation body 4 indentations.Electric conductor 1, core body 5, core body securing member 2, silicon rubber insulation body 4, fixing body 7 connect as one.Described connected mode also can adopt poured with epoxy resin to connect.
Fixing body 7 of the present utility model is bolt assemblies.Electric conductor 1 also is that head part adopts cast aluminium or malleable iron foundry goods.Apart from the enclosed slot that 10mm place, its bottom surface opens a dark wide 10mm of 7.5mm, be used for fit sealing at electric conductor 1 with the core body zinc oxide valve plate.Fixing body 7 is that the set bolt assembly is made up of screw rod, nut and packing ring, and the enclosed slot also opening a dark wide 10mm of 7.5mm apart from its end face 10mm place is used for the fit sealing with the core body zinc oxide valve plate.The shovel mouth 6 that on fixing body, has a card instrument to use in addition.
Overcoat silicon rubber insulation body 4, two main insulation ends are mended flat with silicon rubber filling material 3 after the overall fixed.
