Abstract
The utility model relates to a conjoined insulated shielding cover for 10 kV line ceramic draw bars and wires, which comprises a wire insulated shielding cover and a ceramic draw bar insulated shielding cover which is integrated with the wire insulated shielding cover. The conjoined insulated shielding cover has harder material quality, is not easy to damage, has smooth surface, is easy to check,is convenient to install, and has high insulation strength which reaches 45 kV*min, the shape thereof is matched with a wire, a ceramic draw bar and a stretching line clamp, thereby the conjoined insulated shielding cover can effectively cover electrified devices, has high safety coefficients, and can guarantee the safety of people and devices.
Description
Technical field
The utility model relates to a kind of distribution line live working instrument, relates in particular to the conjuncted insulation mask of a kind of 10kV of being used for circuit porcelain pull-rod and lead.
Background technology
In 10kV circuit charged for replacement was remained silent the process of loading bar knife, the operating personnel need wear shelves and finish the bar cutter and change, because the about 90cm of two-phase wire pitch, safe distance is not enough when wearing grade, need increase the measure of covering of insulating on lead and porcelain pull-rod.The means of originally taking are at porcelain pull-rod and lead place bag empire cloth.Empire cloth is soft shading tool, and is easy to carry, highly versatile, but dielectric strength is low, has only 20kV*min, and fragile, and be difficult for discovering after damaging.Action is loaded down with trivial details when carrying out masking work with empire cloth, needs clamp, owing to need the distance of bag, needs the polylith empire cloth, also will splice in two empire cloth junctions.
Therefore, operating personnel and electrified body close together in the plug-in strip operation process on changing bar, and the employing empire cloth covers, and has the lower problem of coefficient of safety.
Summary of the invention
The purpose of this utility model provides the conjuncted insulation mask of a kind of 10kV of being used for circuit porcelain pull-rod and lead exactly in order to address the above problem, covering insulate to porcelain pull-rod and lead covers, and has guaranteed operating personnel's safety.
The purpose of this utility model is achieved in that
The utility model discloses the conjuncted insulation mask of a kind of 10kV of being used for circuit porcelain pull-rod and lead, comprise wire insulation mask and integrated with it porcelain pull-rod insulation mask.
In above-mentioned conjuncted insulation mask, the cross section of described wire insulation mask is narrower than the cross section of described porcelain pull-rod insulation mask.
In above-mentioned conjuncted insulation mask, conjuncted insulation mask is moulded the polypropylene stripper plate by calcium and is processed.
In above-mentioned conjuncted insulation mask, conjuncted insulation mask is provided with the rinforcement bar of some strip projections.
The utlity model has following characteristics: the conjuncted insulation mask of the utility model quality is harder, and is not fragile, and smooth surface is easy to check that easy for installation, the dielectric strength height reaches 45kV*min, and shape and lead, porcelain pull-rod and strain clamp are complementary.Use conjuncted insulation mask coefficient of safety height, can guarantee personnel, device security.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Referring to Fig. 1, the utility model is used for the conjuncted insulation mask of 10kV circuit porcelain pull-rod and lead, comprise wire insulation mask 2 and integrated with it porcelain pull-rod insulation mask 1, wire insulation mask 2 is used to cover lead, the cross section of this part is narrower, and porcelain pull-rod insulation mask 1 is used to cover the porcelain pull-rod, so cross section broad of this part, need be wider than and cover porcelain pull-rod width, be respectively equipped with the rinforcement bar 3 of three strips on the described conjuncted insulation mask outer surface, the conjuncted insulation mask of the utility model utilizes calcium to mould polypropylene stripper plate bending machining and forms, the dielectric strength height, reaching 45kV*min does not have flashover, puncture, phenomenon such as overheated meets GB/T18037-2000 and electrical safe working order promulgated by the ministries or commissions of the Central Government electrical test standard-required about insulating tool, texture material is hard, density 〉=1.3g/cm2, vicat softening temperature 〉=142 ℃, hot strength 〉=15Mpa, bending strength 〉=30Mpa, impact strength 〉=3KJ/m
2, not fragile, smooth surface is easy to check.The making of the conjuncted insulation mask of the utility model considered fully porcelain pull-rod, lead with and connect the characteristics of the strain clamp of usefulness, one is big, is used to cover porcelain pull-rod and strain clamp, the other end is then long and narrow, be used to cover lead.
Above embodiment is only for the usefulness that the utility model is described, but not to restriction of the present utility model, person skilled in the relevant technique, under the situation that does not break away from spirit and scope of the present utility model, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present utility model, should be limited by each claim.
Claims (4)
1. a conjuncted insulation mask that is used for 10kV circuit porcelain pull-rod and lead is characterized in that, this conjuncted insulation mask comprises wire insulation mask and integrated with it porcelain pull-rod insulation mask.
2. conjuncted insulation mask as claimed in claim 1 is characterized in that, the cross section of described wire insulation mask is narrower than the cross section of described porcelain pull-rod insulation mask.
3. conjuncted insulation mask as claimed in claim 1 is characterized in that, described conjuncted insulation mask is moulded the polypropylene stripper plate by calcium and processed.
4. as each described conjuncted insulation mask of claim 1 to 3, it is characterized in that described conjuncted insulation mask is provided with the rinforcement bar of some strip projections.
