Abstract

The utility model relates to a line breakage-preventing porcelain insulator, comprising an upper fitting, an umbrella body, and a lower fitting, wherein the lower end of the upper fitting and the upper end of the umbrella body are mutually embedded and fixedly connected; the upper end of the lower fitting and the lower end of the umbrella body are mutually embedded and fixedly connected; the umbrella body is a porcelain umbrella body; a cavity is formed among the upper fitting, the umbrella body, and the lower fitting; an insulating tube is arranged inside the cavity; a magnetic pipe, a resistor disc, and a spring are respectively arranged inside the insulating tube from top to bottom; and the upper and lower ends of the magnetic pipe are respectively provided with truncated cone-shaped copper sheets. The line breakage-preventing porcelain insulator is strong in ageing resistance and long in service life.

Description

A kind of anti-broken string porcelain insulator
Technical field
The utility model relates to electric power equipment technical field, in particular for the insulator of transmission line, power distribution circuit and transformer station in the 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, they have solved the safety problems such as electric current corridor that plain conductor originally has, but the overvoltage that causes owing to reasons such as thunderbolts breaks in actual use, the situation that makes whole electric line produce operation troubles happens occasionally, especially China's southern area, the meteorology that lightning flashes and thunder rumbles is more frequent, has influenced the normal power supply of gauze so greatly, has caused tremendous loss to national economy.Anti-broken string 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 defectives such as ageing resistace relatively poor and useful life is short in rubber-like umbrella body, was urgent problem so make a kind of useful life long anti-broken string insulator.
Summary of the invention
Goal of the invention: the purpose of this utility model is in order to overcome deficiency of the prior art, to provide a kind of ageing resistance strong, the anti-broken string porcelain insulator of long service life.
Technical scheme: in order to solve the problems of the technologies described above, a kind of anti-broken string porcelain insulator described in the utility model, it comprises gold utensil, umbrella body and following gold utensil, described lower end of going up gold utensil is connected surely with the upper end phase build-in of umbrella body, the described upper end of gold utensil down is connected surely with the lower end phase build-in of umbrella body, described umbrella body is porcelain umbrella body, the described gold utensil of going up, form a cavity between umbrella body and the following gold utensil, in described cavity, be provided with insulated tube, in described insulated tube, be respectively equipped with magnetic tube from top to bottom, resistor disc and spring are 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 the gold utensil down described.
Described resistor disc is for being nonlinear zinc oxide resistance sheet.
Beneficial effect: the utility model compared with prior art, its remarkable advantage is: the utility model overall structure is simple, adopts porcelain umbrella body, has effectively improved ageing resistance, has improved useful life greatly simultaneously; In use, when Lightning Over-voltage is attacked, as long as superpotential amplitude jeopardizes system's security of operation, gap between the inner copper sheet of insulator will the moment conducting, thereby overvoltage is leaked into the earth by non-linear zinc oxide resistance sheet to be avoided building arc because of overvoltage and blows lead, cause the generation of system's large-area power-cuts or secondary accident, guarantee system safety operation.

Fig. 1 is structural representation of the present utility model;
Fig. 2 goes up gold utensil, umbrella body and following gold utensil and internal structure schematic diagram thereof described in the utility model.
Wherein:
1, goes up gold utensil; 2, umbrella body; 3, following gold utensil; 4, insulated tube; 5, magnetic tube; 6, resistor disc; 7, spring; 8, copper sheet; 9, clip; 10, ground joint
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As depicted in figs. 1 and 2, a kind of anti-broken string porcelain insulator described in the utility model, it comprises gold utensil 1, umbrella body 2 and following gold utensil 3, described lower end of going up gold utensil 1 is connected surely with the upper end phase build-in of umbrella body 2, the described upper end of gold utensil 3 down is connected surely with the lower end phase build-in of umbrella body 2, described umbrella body 2 is porcelain umbrella body, the described gold utensil 1 of going up, form a cavity between umbrella body 2 and the following gold utensil 3, in described cavity, be provided with insulated tube 4, in described insulated tube 4, be respectively equipped with magnetic tube 5 from top to bottom, resistor disc 6 and spring 7 are 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 the gold utensil 3 down described; Described resistor disc 6 is for being nonlinear zinc oxide resistance sheet.The utility model overall structure is simple, adopts porcelain umbrella body, has effectively improved ageing resistance, has improved useful life greatly simultaneously; In use, when Lightning Over-voltage is attacked, as long as superpotential amplitude jeopardizes system's security of operation, gap between the inner copper sheet of insulator will the moment conducting, thereby overvoltage is leaked into the earth by non-linear zinc oxide resistance sheet to be avoided building arc because of overvoltage and blows lead, cause the generation of system's large-area power-cuts or secondary accident, guarantee system safety operation.
The utility model provides a kind of thinking and method; method and the approach of this technical scheme of specific implementation are a lot; the above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art, under the prerequisite that does not break away from the utility model principle, can also make some improvements and modifications; these improvements and modifications also should be considered as protection range of the present utility model, in the present embodiment not clear and definite each part all available prior art realized.
