Description

A kind of combined pin type arrester
Technical field
A kind of combined pin type arrester is the utility model is related to, belongs to electrical equipment technical field.
Background technology
It facts have proved that, to preventing insulated conductor breakage caused by lightning stroke, overvoltage protection device has good protective action.Overvoltage is protected Shield device mainly has two kinds of " puncture " and " not puncturing ".The purpose of puncture is the insulated conductor bare wire allowed near insulator, makes work Frequency electric arc arc root shifts, and the overvoltage protection device of " not puncturing " will not also cause insulated conductor to damage by blocking power frequency continued flow Wound, 10kV overhead transmission lines are subject to induced lightening invasion and attack, are the main originals for causing overhead transmission line thunderbolt because dielectric level is low Cause.
As China town and country large scale electric network is transformed, urban power distribution network largely employs insulated overhead line, insulated conductor Really corridor and the safety problem that bare conductor can't resolve are solved, compared with cable, there is small investment, built fast excellent Point, but its lightning-caused breaking problem is very prominent, solves lightning-caused breaking to ensure that insulated overhead line is that power system is worked as safely One of preceding main Problems.
The content of the invention
The utility model will solve technical problem:The shortcomings that overcoming above-mentioned technology;It is proposed a kind of collection arrester and insulation The pin type arrester that son is integrated.
In order to solve the above-mentioned technical problem, the utility model proposes technical scheme be:A kind of combined pin type arrester, Including:Hollow silastic material, the penetrating electrodes at the top of the silastic material, installed in the silastic material The grounding screw of bottom and relative and spaced first, second sparking electrode in the silastic material;Institute The first sparking electrode is stated to be connected with the penetrating electrodes by the first high-voltage resistor;Second sparking electrode is high by second Piezoresistance device connects the grounding screw with some resistor discs;First, second sparking electrode, the first high-voltage resistor, Two high-voltage resistors and resistor disc are wrapped with expoxy glass fiber tube;The expoxy glass fiber tube is located at the silastic material It is interior;There is multilayer full skirt outside the silastic material.
Such scheme, which further improves, to be:The penetrating electrodes are arranged in a groove;Have on the groove There is wire pressing plate;The wire pressing plate is arranged on the silastic material top by bolt.
Such scheme, which further improves, to be:The resistor disc is zinc oxide resistance sheet.
Combined pin type arrester provided by the utility model, built in air gap, lightening strikes are met with distribution line When, sparking electrode plays arrester effect, release lightning voltage, electric current, and the insulation of its air gap recovers immediately, blocks follow-up power frequency Electric current, follow-up power current is avoided to the burn of wire and insulator, prevent distribution line outlet protection act tripping operation.Normal shape State, arrester flow only through capacitance current, the leakage current of trace such as common porcelain insulator(Airspace insulation produces), Arrester is in off position, the insulation degradation rate of combined pin type arrester is reached minimum, and then arrester is exempted from Safeguard.
Brief description of the drawings
The utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is a preferred embodiment structural representation of the utility model embodiment.
Embodiment
Embodiment
The combined pin type arrester of the present embodiment, such as Fig. 1, including:Hollow silastic material 1, installed in silicon rubber The penetrating electrodes 6 at the top of overcoat 1, the grounding screw 9 installed in the bottom of silastic material 1 and in silastic material 1 Relative and spaced first sparking electrode 2a, the second sparking electrode 2b;First sparking electrode 2a passes through the first high-tension resistive Device 3a is connected with penetrating electrodes 6;Second sparking electrode 2b passes through the second high-voltage resistor 3b and some non-linear ZnO resistors Piece 4 connects grounding screw 9;In order that connect between more reliable first high-voltage resistor 3a and penetrating electrodes 6, non-linear zinc oxide Connected between resistor disc 4 and grounding screw 9 by connection electrode 5.Connection electrode 5, the first sparking electrode 2a, the second electric discharge electricity Pole 2b, the first high-voltage resistor 3a, the second high-voltage resistor 3b and resistor disc 4 are wrapped with high-strength epoxy glass fiber tube 10; Expoxy glass fiber tube 10 is located in silastic material 1 and fills clearance spaces therein;There is multi-layer umbrella outside silastic material 1 Skirt.
Penetrating electrodes 9 are arranged in a groove;There is wire pressing plate 7 on groove;Wire pressing plate 7 is pacified by bolt 8 Mounted in the top of silastic material 1;The position of the respective slot of wire pressing plate 7 has projection, when distribution wire is placed in groove simultaneously When compressing wire pressing plate 7, sealing is produced, can prevent gas and moisture from entering the position that distribution wire is punctured.
The combined pin type arrester that the present embodiment provides, it is one to collect metal oxide arrester and composite insulator purposes Body, built in air gap.When distribution line meets with lightening strikes, the breakdown ionization of air between sparking electrode, arrester is led Logical, so as to play arrester effect, release lightning voltage, electric current, then the air gap insulation recovers immediately, blocks follow-up power frequency electric Stream, avoids follow-up power current to the burn of wire and insulator, prevents distribution line outlet protection act tripping operation.
Normal condition, arrester flow only through capacitance current, the leakage current of trace such as common porcelain insulator(Air Spacer insulator produces), arrester is in off position, consistent with common insulator, reaches the insulation degradation rate of arrester Minimum, arrester is non-maintaining.
The present embodiment provide combined pin type arrester use silicone rubber material overcoat, have good hydrophobicity, Ageing resistance, proof tracking and electrical erosion resistance, it is filled with high-strength epoxy glass fiber tube 10, has very high resist Stretching and bending strength.
The combined pin type arrester that the present embodiment provides is to substitute first wife's electric line overvoltage protection device, gapless oxidation The new generation product of zinc arrester and porcelain pin type insulator.One group of the installation per 200m, reachable in existing operating distribution line To 94% lightning protection effect, greatly reduce distribution line thunderbolt rate of insulation flashover, lightning-caused breaking rate, electric substation's distribution line and jump Lock rate, power supply reliability is improved, reduce maintenance workload and maintenance cost.
The utility model is not limited to the concrete technical scheme described in above-described embodiment, in addition to the implementation, this practicality It is new to have other embodiment.All technical schemes formed using equivalent substitution, it is the guarantor of the requires of the utility model Protect scope.
