Abstract
The utility model relates to the field of lightning arresters, and discloses a pillar type lightning arrester for a power distribution cabinet. The pillar type lightning arrester is characterized by comprising an epoxy pipe, an insulating outer cover, resistor discs, an upper electrode and a lower electrode, wherein the insulating outer cover is arranged outside the epoxy pipe, the resistor discs are arranged in the epoxy pipe in a stacked mode, the upper electrode is arranged at the upper end of the epoxy pipe, and the lower electrode is arranged at the lower end of the epoxy pipe. The pillar type lightning arrester for the power distribution cabinet has the dual functions of insulation supporting and overvoltage limiting, achieves the dual effects of insulators and a lightning arrester, and has the advantages of being simple in structure, small in size, and convenient to install and popularize.
Description
Technical field
The utility model relates to lightning arrester field, and particularly a kind of power distribution cabinet column support type lightning arrester, is a kind of novel product that can play post insulator and lightning arrester double action using in power distribution cabinet.
Background technology
As everyone knows, power distribution cabinet is a kind of switchgear assembly and control appliance.It is as power center (PC) and main switching compound, mainly with control, supervision, the measuring and protection done power circuit, main power consumption equipment; Be part indispensable in distribution system, its importance is self-evident; And in each station power distribution cabinet, insulator and lightning arrester are absolutely necessary.Along with more and more miniaturization of power distribution cabinet, the installing space in cabinet is also more and more less, when user buys zinc oxide arrester, also needs to buy post insulator, take up room large, and Financial cost is high.
Utility model content
The purpose of this utility model is to provide a kind of power distribution cabinet column support type lightning arrester, and this lightning arrester has had the effect of lightning arrester and post insulator concurrently, has reduced to take up room and reduced Financial cost.
In order to achieve the above object, the utility model is achieved by the following technical solutions.
A power distribution cabinet column support type lightning arrester, is characterized in that, comprises epoxy tube, is arranged on the insulating coating outside epoxy tube, is stacked in the resistor disc in epoxy tube, and the top electrode and the bottom electrode that is arranged on epoxy tube lower end that are arranged on epoxy tube upper end.
Feature of the present utility model and improvement are:
Described epoxy tube is epoxy fibreglass stringing.
Described resistor disc is zinc oxide resistance sheet.
Described top electrode, bottom electrode are metal electrode.
Described insulating coating is unsaturated polyester (UP) BMC insulating case.
Described insulating coating has insulated umbrella structure.
Power distribution cabinet of the present utility model column support type lightning arrester, comprises epoxy tube, is arranged on the insulating coating outside epoxy tube, is stacked in the resistor disc in epoxy tube, and the top electrode and the bottom electrode that is arranged on epoxy tube lower end that are arranged on epoxy tube upper end.The power distribution cabinet of said structure has the dual-use function of insulating supporting and overvoltage restriction with column support type lightning arrester, realized the double effects of insulator and lightning arrester, has the advantages such as simple in structure, volume is little, is convenient to install and promotes.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the structural representation of column support type lightning arrester for a kind of power distribution cabinet of the present utility model.
In figure: 1, top electrode; 2, insulating coating; 3, epoxy tube; 4, resistor disc; 5, bottom electrode.
Embodiment
With reference to Fig. 1, it is the structural representation of column support type lightning arrester for the utility model power distribution cabinet.This power distribution cabinet column support type lightning arrester, comprises top electrode 1, insulating coating 2, epoxy tube 3, resistor disc 4, bottom electrode 5.Wherein, multi-disc zinc oxide resistance sheet 4 is stacked in epoxy tube 3 inside, two ends are fixed and are sealed by top electrode 1 and bottom electrode 5, top electrode 1, multi-disc zinc oxide resistance sheet 4, bottom electrode 5 are directly serially connected in epoxy tube 3 inside, form lightning arrester core body, at epoxy tube 3, be outside equipped with the insulating supporting that insulating coating 2 forms.
Wherein, top electrode 1, bottom electrode 5 adopt and are metal electrode, play the effect of fixed resistance sheet and electrical connection simultaneously.
Wherein, epoxy tube 3 adopts epoxy fibreglass cloth, plays isolation resistance sheet 4 and insulating coating 2 and the effect that increases product mechanical strength.
Wherein, resistor disc 4 adopts zinc oxide resistance sheet.
In addition, lightning arrester core body forms unsaturated polyester (UP) BMC insulating coating 2 by unsaturated polyester (UP) BMC (DMC) compacting, and insulating coating has insulated umbrella structure, playing increases creepage distance, gains in strength, its effect and the traditional identical object of post insulator.
The utility model is after having taked technique scheme, can substitute traditional post insulator and zinc oxide arrester, both the development trend that had adapted to switch cubicle miniaturization, alleviated the workload of design and buying simultaneously, for user has reduced financial burden, it is little, simple in structure, the powerful novel product of a kind of volume.
Although below by reference to the accompanying drawings embodiment of the present utility model is described, but the utility model is not limited to above-mentioned specific embodiments and applications field, above-mentioned specific embodiments is only schematic, guiding, rather than restrictive.Those of ordinary skill in the art, under the enlightenment of specification, in the situation that do not depart from the scope that the utility model claim is protected, can also make a variety of forms, and these all belong to the row of the utility model protection.
