Abstract
The utility model relates to a couple-uncouple type lightning arrester with a disconnector. The technical scheme is that a supporting insulator is installed on a crossarm through a mounting rack, and the lightning arrester is installed in a top connecting nut and a bottom connecting nut, and is fastened by adjusting bolts, and the lightning arrester after being fixed is installed on a bottom connecting base, a live part lead is arranged on an upper lead connecting bolt, the disconnector is installed under the bottom contact of the lightning arrester or under the bottom connecting base of the supporting insulator, and the disconnector can automatically release when the lightning arrester fails, and then the lightning arrester exits from the operation. The couple-uncouple type lightning arrester has the beneficial effects that the lightning arrester can release at the first time after failing, thereby reducing the line accident patrol and treatment time, and the lightning arrester of the line can be conveniently installed and detached under the charged condition through an insulating rod on the ground, thereby greatly reducing the workload of each check or of the detachment of the lightning arrester, reducing the outage cost, and increasing the power supply reliability at the maximum degree.
Description
One, technical field:
The utility model relates to a kind of lightning arrester, particularly a kind of dislodging formula band disconnector lightning arrester.
Two, background technology:
In the power distribution network of present power industry at home, lightning arrester generally all is directly to be fixed on the cross-arm of electric pole insulator below, and the upper and lower lead-in wire of lightning arrester directly links to each other with lightning arrester, after lightning arrester breaks down, installs and change the power failure that all needs the whole piece circuit.In addition, need to detect or when changeing lightning arrester, increased the time and the number of times of line outage greatly when lightning arrester arrives useful life period or breaks down, very inconvenient to the line security operational management.Although lightning arrester has good effect to reducing lightning outage rate, the 6-10kV zinc oxide arrester occurs body again and again and punctures and explosion accident behind operation 4-5, and the accident potential that itself exists is difficult to find and eliminate in line service.
Three, summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and a kind of dislodging formula band disconnector lightning arrester is provided, and has reduced each detection or has changed the workload of lightning arrester, has reduced loss of outage, and has improved power supply reliability to greatest extent.
Its technical scheme is: by mounting bracket, supporting insulator, last lead-in wire connecting bolt, the top connects pedestal, the top connects contact, the operation draw ring, among the attaching nut of top, the bottom attaching nut, the bottom connects contact, the ground connection connecting line is connected pedestal and constitutes with the bottom, use mounting bracket that supporting insulator is installed on the cross-arm, lightning arrester is installed among the attaching nut of top and the bottom attaching nut in, use the adjusting bolt fastening, the lightning arrester that fixes is installed in the bottom to be connected on the pedestal, the live part lead-in wire is installed on the lead-in wire connecting bolt, disconnector is installed in the lightning arrester bottom and connects the contact below or be installed in supporting insulator bottom connection pedestal below, when lightning arrester breaks down, disconnector is thrown off automatically, and lightning arrester is out of service.
The earth connection of above-mentioned disconnector adopts the braiding annealed copper wire, length is set to after lightning arrester body separates enough insulation distances are arranged, disconnector is to utilize the short circuit current in the fault lightning arrester to produce arcing in disconnector, ignites the purpose that the thermal explosion element reaches disengaging.
When lightning arrester was in normal operating conditions, disconnector was failure to actuate and is Low ESR (comparing with lightning arrester), does not influence the protective feature of former operating state of system and lightning arrester, guaranteed uninterrupted power supply, made lightning arrester really reach " non-maintaining " instructions for use.
The beneficial effects of the utility model are: the system rated voltage of being adapted to be mounted within is on 10kV and the following circuit.It not only can break down afterwards at lightning arrester, and the very first time breaks away from, having reduced line accident makes an inspection tour and the processing time, and can utilize insulating rod under charged situation, to load and unload the lightning arrester of this circuit easily on ground, do not influence normal power supply, also need not work high above the ground, thereby significantly reduced each detection or changed the workload of lightning arrester, reduced loss of outage, and improved power supply reliability to greatest extent.
Four, description of drawings:
Accompanying drawing 1 is the structural representation of a kind of embodiment of the present utility model;
Accompanying drawing 2 is structural representations of another embodiment of the present utility model.
Five, embodiment:
Embodiment 1: in conjunction with the accompanying drawings 1; the utility model will be further described; its technical scheme is: by mounting bracket 1; supporting insulator 2; last lead-in wire connecting bolt 3; the top connects pedestal 4; the top connects contact 5; operation draw ring 6; among the top attaching nut 7; bottom attaching nut 8; the bottom connects contact 9; ground connection connecting line 11 is connected pedestal 12 and constitutes with the bottom; use mounting bracket 1 that supporting insulator 2 is installed on the cross-arm; lightning arrester is installed among the top attaching nut 7 and bottom attaching nut 8 in; use the adjusting bolt fastening; the lightning arrester that fixes is installed in the bottom to be connected on the pedestal 12; the live part lead-in wire is installed on the lead-in wire connecting bolt 3; wherein; disconnector 10 is installed in the lightning arrester bottom and connects contact 9 belows; after all installing; use insulating rod operating operation draw ring 6 dislodging lightning arresters; when lightning arrester breaks down; disconnector is thrown off automatically; lightning arrester is out of service; certainly; existing lightning arrester is not necessarily the same with the described structure of accompanying drawing with the model or the annexation of supporting insulator, as long as realize that by the dockingundocking device easy disassembly then only belongs to protection range of the present utility model.
The earth connection of above-mentioned disconnector adopts the braiding annealed copper wire, and the about 300mm of length is to guarantee after lightning arrester body separates enough insulation distances being arranged.
Embodiment 2: with reference to accompanying drawing 2, other structures are the same, and disconnector 10 is installed in the supporting insulator bottom and connects pedestal 12 belows, after all installing, use insulating rod operating operation draw ring 6 dislodging lightning arresters.
