Abstract

The utility model relates to a composite casing zinc oxide lightning arrester used for transmission lines in 6 to 10KV. The utility model is composed of a wire connecting terminal 1, a harmonious press cover 2, an insulating casing 3, a core body 4, an insulating bracket 5, a lightning monitor 6 and a disengaging device 7, wherein the inner of the insulating casing 3 is arranged inside the core body 4, and the upper end of the insulating casing is provided with the harmonious press cover 2; the lower part of the insulating casing is provided with the insulating bracket 5, and the upper part of the harmonious press cover 2 is provided with the wire connecting terminal 1; the lower end of the harmonious press cover 2 is in contact with the core body. The lower part of the insulating bracket 5 is provided with the lightning monitor 6 of which the lower part if provided with the disengaging device 7. The lightning arrester has the advantages of small volume, light weight and reliable operation, and the utility model not only can be utilized to prevent lightning over voltage, but also has the advantages of reducing the amplitude value of over voltage caused by the inner operation of a system, reducing tripping accident rate and improving the line lightning resisting level of the transmission lines and power supplying reliability.

Description

A kind of composite sheath zinc oxide arrester
Technical field:
The utility model relates to a kind of safety guard that is used for 6~10KV transmission line.
Background technology:
Fast development along with the development of the national economy and industrial and agricultural production, requirement to the transmission line reliability is more and more higher, prevent the power outage that causes owing to transmission line of lightning strike and power transmission and transforming equipment, thus avoid or reduce to produce, life impacts the important topic that becomes power supply department.At present, nearly ten thousand phase leakage conductors have been installed on the 35-500KV ultra-high-tension power transmission line, and have been obtained good lightning protection effect, made the operation of power networks reliability improve greatly.But because the line insulation level is lower, and tripping rate with lightning strike is very high, various controller switching equipments damage comparatively serious when lightening activity, greatly affect the reliability and the electric network security of power supply in 6~10KV intermediate distribution system.Up to the present, the lightning protection problem of 6~10KV distribution system is solved as yet fully, and normally used distribution lightning arrester and power station lightning arrester can only play the effect of over-voltage, to the few of effect of line thunder protection.
Summary of the invention:
The purpose of this utility model is to provide a kind of composite sheath zinc oxide arrester that can effectively solve 6~10KV transmission line lightning protection problem.
The utility model is to realize like this.This kind lightning arrester has arrester without gaps and two kinds of structures of external series gap lightning arrester, form by binding post, pressure equalizing cover, insulating coating, core body, insulator support, lightning monitoring device and disconnector, core body is housed in the insulating coating, and the upper end is provided with pressure equalizing cover, and the below is provided with insulator support; The pressure equalizing cover top is provided with binding post, and its lower end contacts with core body; The insulator support below is provided with the lightning monitoring device, and the monitor below is provided with disconnector (sometimes can be without the lightning monitoring device, insulator support directly links to each other with disconnector).During use, select the frame mode of lightning arrester for use according to the transmission line concrete condition, satisfying the transmission line lightning protection and guaranteeing under the prerequisite of lightning arrester reliability service, determine the electric parameter (direct current 1mA reference voltage, residual voltage, big electric current tolerance, rated voltage etc.) of lightning arrester, it is connected in parallel in 6~10KV line insulator two ends.
The utility model volume is little, and is in light weight, reliable operation, utilize it can not only prevent lightning overvoltage, also can reduce the overvoltage amplitude that causes by the internal system operation, reduce the tripping operation rate of failure, improve transmission line lightning withstand level and power supply reliability, have great practicality and applicability.
Description of drawings:
Fig. 1 is the utility model gapless structure schematic diagram.Fig. 2 is the utility model band gap structural representation.
Embodiment:
The utility model is provided by following examples, is illustrated below in conjunction with accompanying drawing.
As shown in the figure, the utility model is made up of binding post 1, pressure equalizing cover 2, insulating coating 3, core body 4, insulator support 5, lightning monitoring device 6 and disconnector 7, its structure, assembled relation are as follows: core body 4 is housed in the insulating coating 3, and the upper end is provided with pressure equalizing cover 2, and the below is provided with insulator support 5; Pressure equalizing cover 2 tops are provided with binding post 1, and its lower end contacts with core body 4; Insulator support 5 belows are provided with lightning monitoring device 6, and monitor 6 belows are provided with disconnector 7.Wherein, insulating coating 3 adopts HTV or RTV silicon rubber to make, by large and small, in the umbrella body in three kinds of umbrellas footpaths constitute and adopt the overall sulfur metallization processes once molding formed on core body 4 surfaces.Adorn small dimension, high-energy in the Du Li rammer insulated tube of core body 4 by high strength, high insulating property, high energy ZnO resistors sheet and metal electrode that voltage-current characteristic is good constitute.Insulator support 5 adopts the Du Li rammer insulating material of high strength, high-insulativity to make, and plays the insulation supporting role in disconnector 7 action backs.Lightning monitoring device 6 is the small, dedicated discharge counter, and the upper end links to each other with line terminals under the lightning arrester by insulator support 5, plays monitoring lightning arrester operating state and observation lightening activity.Disconnector 7 is special-purpose heat explosion type disconnector, and the upper end links to each other with lightning monitoring device lower connecting terminal, and the lower end links to each other with the overhead line structures earth electrode by connecting lead, plays lightning arrester fault disengaging effect.Described the utility model band gap (or claiming plug-in gap) structure (see figure 2) basic structure is identical with gapless structure, difference is that the binding post top connects the crooked guide rod 8 of an aluminum, bottom electrode as the gap, and form the discharging gap of " pure air " between the high-voltage conducting wires (gap top electrode), play the effect of shielding system power-frequency voltage.
