The utility model is a lightning arrester device with compound functions of lightning protection, supporting insulation and earthing, which removes the six fault points, has the advantages of unique structure, energy saving, light and attractive appearance, safe and convenient usage and reliable performance, and is upgraded and updated lightning arrester equipment.
Description
Technical field:
The utility model belongs to the electric power equipment that the power transmission and distribution overhead transmission line is used.A kind of column support type arrester device that has earth brace and penetrating cable clamp.It relate generally to a kind of electric power provide and deliver in the electric overhead transmission line lightning protection and utilize penetrating cable clamp not need the peeling support wire that insulate, and electrical verification earth brace to be opened/closed at any time comes the column support type arrester device of electrical verification ground connection.
Background technology:
The natural phenomena that warms along with the high speed development and the global weather of China's economic construction, the generation of thunder and lightning (static) disaster is very frequent, the loss that thunderbolt causes is also more and more serious, so the lightning protection work of high pressure transmission and distribution line is also increasingly important, moves towards legal, scientific just gradually and standardization.
The insulating process of the overhead wire of the following transmission of electricity of town and country 10KV at present is very fast; to exist the positions of continuing such as switch, lightning arrester, binding clip, pole many but because the zones such as distribution transforming on the line bar are common; caused operation troubles many, the insulation safety protective condition is poor, installs numerous and diverse; maintenance difficulties is big; and the cost height, the live line working condition is poor, or the like serial problem; especially some conventional arrester devices can not adapt to the needs of electrical network modernization construction fully.
Summary of the invention:
The utility model is exactly a kind of column support type arrester device that has earth brace and penetrating cable clamp and busbar of invention; it is mainly used in provide and deliver lightning protection in the electric overhead transmission line of electric power; it is that a kind of electrical verification earth brace that utilizes the penetrating cable clamp on the busbar to come not peeling supports insulative lead and utilization to open or close at any time comes the arrester device of electrical verification ground connection.
Needs according to China recent years consumers' opinions and electric network reconstruction, for the connection to distribution transforming system and circuit on the bar can reach simplification, and further increase security of operation, need a kind of tape insulation folder pillar function that has, lightning-arrest function, the energising function that can puncture, the electrical verification grounding function is the synthetic overcoat zinc oxide lightning arrester of the multiduty combining form of one.Known lightning arrester is because its structure is single, to increase a cross-arm during installation more, want peeling during installation, not only inconvenient, increase installation cost, and the dangerous discharge accident or the like that causes easily, all disadvantages of the old-fashioned lightning arrester of this class can not adapt to fully makes the requirement of line materials to " low energy consumption; fault-free, long-life, exemption from inspection " development.
The purpose of this utility model is invented a kind of with electrical verification earth brace and the lightning arrester of exempting from the peeling penetrating cable clamp exactly.The utility model is by modified model lightning arrester 1, busbar 2, and insulation electrical verification earth brace 3, insulated conductor penetrating cable clamp 4, binding post trip bolt 5 and insulating shield 6 assemble.On busbar 2 (as figure), fixedly mount modified model lightning arrester 1 respectively, electrical verification earth brace 3, insulated conductor penetrating cable clamp 4, with binding post trip bolt 5, insulating shield 6 is the insulating protection covers that are wrapped in all electrical equipment contacts of the utility model and live metal spare outside, it adopts silastic material, not only all live parts with this lightning arrester are wrapped in the inside fully, and make whole outward appearance clean and tidy, good insulation performance is arranged, anti-flammability and ageing resistance, the generation of outside destroy accident can be effectively avoided in the design of employing all insulation.Adopt lightning arrester of the present invention not only can reduce by a former lightning arrester cross-arm, also can reduce a fixedly post insulator of usefulness of drop wire, be exactly to have reduced seven places peeling point like this, reduced fault point, six places, simplified circuit, adopt penetrating cable clamp of the present invention, make power transmission line when mounted without peeling, directly puncture energising, increased the fail safe of lightning arrester, the present invention is protected by futuramic insulating cover face shield with the insulation of former needs 7 place's peeling points and at a place and in its outside, has really accomplished omnidistance insulation, for advantage has been created in the safety live line working.
