Description
[technical field]
The utility model relates to Inflatable ring main unit test field, particularly relates to a kind of plain type withstand voltage test instrument.
[background technology]
The switchgear of Inflatable ring main unit to be a kind of with gas be insulating medium, main application fields can be divided into primary power distribution equipment and secondary power distribution equipment, only because of gas-filling cabinet compact conformation, size is little, on present market, a lot of ring main unit all uses gas-filling cabinet, test daily dispatching from the factory and carry out in type approval test process, power frequency withstand test is an of paramount importance pilot project, to various electric equipment products, electrical equipment, insulating material etc. carry out the dielectric(al) test under assigned voltage, to examine the dielectric level of product, find the insulation defect of test specimen, weigh superpotential ability, the test instrument of the withstand voltage test of existing KYN28 series switch can not examine the dielectric level of Inflatable ring main unit, the compact conformation of Inflatable ring main unit own, the advantage that size is little causes certain difficulty to withstand voltage test equally, in withstand voltage test process, in cabinet, each alternate and relatively insulation distance is difficult to ensure, as test will go on, need installing cables badly, and the installation difficulty of cable is large, high in cost of production shortcoming brings many troubles to manufacturer really.Subject matter is:
1, mounting process aspect, the two large difficult points that traditional cable is installed: 1. due to the structural limitations of switch cubicle, lower outlet insulator is usually apart from ground about 650mm, and the bending radius of 10kV cable is difficult to reach installation effect, needing specially for switch cubicle makes raising bracket, is not good method like this from the aspect such as cost, safety; 2. the annex of installing cables and operation more lengthy and tedious, comprise cable terminal, stud bolt, insulation plug, the annexes such as insulating lid, installation procedure must illustratively carry out, and above annex all need be installed, man-hour is long, through verification experimental verification time and again, installing a cable need about half an hour consuming time, and need two or three personnel to coordinate;
2, cost budgeting aspect, a 10kV cable cost at about 10,000 yuan, three namely 30,000 yuan.
[utility model content]
The purpose of this utility model is to overcome problems of the prior art, provides a kind of and installs quick and that cost is low plain type withstand voltage test instrument.
In order to achieve the above object, the utility model adopts following technical scheme:
Comprise the insulating sleeve be enclosed within ring main unit on lower outlet insulator, in insulating sleeve, be provided with the metal conductive bar for connecting pressure-resistant equipment high-pressure side, metal conductive bar and lower outlet insulator are fixedly linked, and insulating sleeve and metal conductive bar all extend to outside ring main unit.
Adopt between described metal conductive bar and lower outlet insulator and be threaded.
The end of described metal conductive bar outside ring main unit is provided with carries out spacing lever to insulating sleeve, and lever and metal conductive bar are mutually vertical.
Lubrication silicone grease layer is provided with between described insulating sleeve and lower outlet insulator.
Compared with prior art, the utility model has following useful technique effect:
The utility model by descending installing insulating sleeve pipe on outlet insulator in ring main unit, and by metal conductive bar with under occur that insulator is connected, cable can be replaced to be connected with the high-pressure side of pressure-resistant equipment, and meanwhile, insulating sleeve and metal conductive bar all extend to outside ring main unit, can be connected with the high-pressure side of pressure-resistant equipment quickly and easily, without the need to raising bracket, a few minutes just can install, and a people can complete installation, reducing manpower, is also improve greatly to production efficiency; And the utility model no longer needs cable, hinge structure uses cable, and the utility model metal conductive bar and insulating sleeve can reduce costs greatly.
Further, the utility model metal conductive bar and lower outlet insulator are threaded by employing, firmly easy to connect.
Further, the utility model, by arranging lever, carries out spacing to insulating sleeve, occurs on insulator, prevent from coming off under insulating sleeve can be made to be enclosed within securely.
Further, the utility model, by arranging lubrication silicone grease layer, occurs on insulator under insulating sleeve can be facilitated to be quickly installed to, and under occur that insulator forms protection.
[accompanying drawing explanation]
Fig. 1 is structural representation of the present utility model;
Wherein, 1-insulating sleeve; 2-metal conductive bar; 3-pin; Insulator is there is under 4-.
[embodiment]
Below in conjunction with accompanying drawing, the utility model is described in further details.
See Fig. 1, the utility model comprises the insulating sleeve 1 be enclosed within ring main unit on lower outlet insulator 4, is provided with lubrication silicone grease layer between insulating sleeve 1 and lower outlet insulator 4; In insulating sleeve 1, be provided with the metal conductive bar 2 for connecting pressure-resistant equipment high-pressure side, the end of metal conductive bar 2 and lower outlet insulator 4 arranges and coordinates the screw thread of phase to make both be fixedly linked, and insulating sleeve 1 and metal conductive bar 2 all extend to outside ring main unit.
The end providing holes of metal conductive bar 2 outside ring main unit, penetrates lever 3 in hole, lever 3 is mutually vertical with metal conductive bar 2, and lever 3 connects with insulating sleeve 1, and carries out spacing to it, effectively prevents insulating sleeve 1 slippage.
Be below example with XGN86-12 Inflatable ring main unit, lower appearance wherein, insulator installed the utility model, when testing, only needed the metallic conduction stick end outside ring main unit to be connected with pressure-resistant equipment high-pressure side, only need about 5 minutes, can test, install simple and convenient, fast, efficiency value promotes greatly, manpower also greatly reduces simultaneously, and reduce to 1 people from 2-3 people before, production efficiency greatly improves.Cost price of the present utility model, probably at about 0.1 ten thousand yuan, adopts cable relatively, and significant cost of the present utility model reduces.
The utility model is mainly installed and the course of work:
1, first proprietary 10kV insulating sleeve 1 alcohol paper is cleaned, is coated with and spreads lubrication silicone grease, be arranged on lower outlet insulator 4,
2, screwed metal conductive bar 2 is screwed on lower outlet insulator 4, and plugs pin 3, make insulating sleeve 1 be wrapped on lower outlet insulator 4 reliably,
3, the high-pressure side of pressure-resistant equipment is added in metal conductive bar 2, can withstand voltage test be carried out.
Pass through said structure, make test process flexibly simple to operate, quality production control efficiency is improved and plays good impetus, the utility model is confined to above-mentioned cabinet type incessantly, can use for small-sized ring main unit, as the gas-filling cabinets such as XGN86-12, XGN86-40.5 dispatch from the factory voltage-withstand test, type approval test.
