Abstract

The invention relates to a porcelain insulator with a wire breakage preventing function. The porcelain insulator comprises an upper fitting, an umbrella body and a lower fitting, wherein the lower end of the upper fitting is embedded and fixedly connected with the upper end of the umbrella body, the upper end of the lower fitting is embedded and fixedly connected with the lower end of the umbrella body, the umbrella body is a porcelain umbrella body, a cavity is formed among the upper fitting, the umbrella body and the lower fitting, an insulation pipe is arranged in the cavity, a magnetic pipe, a resistance sheet and a spring are respectively arranged in the insulation pipe from top to bottom, and the upper end and the lower end of the magnetic pipe are respectively provided with a truncated cone-shaped copper sheet. The porcelain insulator has the advantages that the aging-resistant performance is high, and the service life is long.

Description

A kind of breaking line preventive porcelain insulator
Technical field
The present invention relates to the power equipment technical field, in particular for the insulator of transmission line, power distribution circuit and transformer station in electric power system, specifically a kind of prevent from being struck by lightning cause the insulator of aerial insulated wire broken string.
Background technology
Existing transmission of electricity power distribution circuit has all adopted insulated conductor, the safety problems such as they have solved that plain conductor originally has electric current corridor, but the overvoltage broken string that causes due to reasons such as thunderbolts in actual use, the situation that makes whole electric line produce operation troubles happens occasionally, especially south China is regional, the meteorology that lightning flashes and thunder rumbles is more frequent, has so greatly affected the normal power supply of gauze, has caused huge loss to national economy.The breaking line preventive insulator can leak into the earth with overvoltage rapidly, has therefore solved the problems referred to above.But in reality was used running, there were the defectives such as ageing resistace relatively poor and useful life is shorter in rubber-like umbrella body, was urgent problem so make a kind of useful life long breaking line preventive insulator.
Summary of the invention
Goal of the invention: the objective of the invention is provides a kind of ageing resistance strong in order to overcome deficiency of the prior art, the breaking line preventive porcelain insulator of long service life.
technical scheme: in order to solve the problems of the technologies described above, a kind of breaking line preventive porcelain insulator of the present invention, it comprises gold utensil, umbrella body and lower gold utensil, the lower end of described upper gold utensil is connected surely with the upper end phase build-in of umbrella body, the upper end of described lower gold utensil is connected surely with the lower end phase build-in of umbrella body, described umbrella body is porcelain umbrella body, described upper gold utensil, form a cavity between umbrella body and lower gold utensil, be provided with insulated tube in described cavity, be respectively equipped with from top to bottom magnetic tube in described insulated tube, resistor disc and spring, be respectively equipped with the copper sheet of truncated cone-shaped at the two ends up and down of described magnetic tube.
The gold utensil top is provided with clip on described.
Be provided with ground joint below described lower gold utensil.
Described resistor disc is for being nonlinear zinc oxide resistance sheet.
Beneficial effect: the present invention compared with prior art, its remarkable advantage is: overall structure of the present invention is simple, adopts porcelain umbrella body, has effectively improved ageing resistance, has greatly improved useful life simultaneously; In use, when having Lightning Over-voltage to attack, as long as superpotential amplitude jeopardizes system's security of operation, gap between the inner copper sheet of insulator will transient switching, thereby overvoltage is leaked into the earth by non-linear zinc oxide resistance sheet to be avoided building arc because of overvoltage and blows wire, cause the generation of system's large-area power-cuts or secondary accident, guarantee system safety operation.

Embodiment
The present invention is further illustrated below in conjunction with drawings and Examples.
as depicted in figs. 1 and 2, a kind of breaking line preventive porcelain insulator of the present invention, it comprises gold utensil 1, umbrella body 2 and lower gold utensil 3, the lower end of described upper gold utensil 1 is connected surely with the upper end phase build-in of umbrella body 2, the upper end of described lower gold utensil 3 is connected surely with the lower end phase build-in of umbrella body 2, described umbrella body 2 is porcelain umbrella body, described upper gold utensil 1, form a cavity between umbrella body 2 and lower gold utensil 3, be provided with insulated tube 4 in described cavity, be respectively equipped with from top to bottom magnetic tube 5 in described insulated tube 4, resistor disc 6 and spring 7, be respectively equipped with the copper sheet 8 of truncated cone-shaped at the two ends up and down of described magnetic tube 5, gold utensil 1 top is provided with clip 9 on described, be provided with ground joint 10 below described lower gold utensil 3, described resistor disc 6 is for being nonlinear zinc oxide resistance sheet.Overall structure of the present invention is simple, adopts porcelain umbrella body, has effectively improved ageing resistance, has greatly improved useful life simultaneously; In use, when having Lightning Over-voltage to attack, as long as superpotential amplitude jeopardizes system's security of operation, gap between the inner copper sheet of insulator will transient switching, thereby overvoltage is leaked into the earth by non-linear zinc oxide resistance sheet to be avoided building arc because of overvoltage and blows wire, cause the generation of system's large-area power-cuts or secondary accident, guarantee system safety operation.
The invention provides a kind of thinking and method; method and the approach of this technical scheme of specific implementation are a lot; the above is only the preferred embodiment of the present invention; should be understood that; for those skilled in the art, under the prerequisite that does not break away from the principle of the invention, can also make some improvements and modifications; these improvements and modifications also should be considered as protection scope of the present invention, in the present embodiment not clear and definite each part all available prior art realized.
