Description
Technical field
The utility model relates to a kind of high voltage overhead cross-arms more particularly to one kind to be mainly used in overhead distribution
Erection insulator crossarm.
Background technique
Cross-arm is the most common fitting in power distribution network, is widely used in overhead distribution, and cross-arm is must not in shaft tower
The component part that can lack, its effect is to support conducting wire, lightning conducter, and to make distribution line for installing insulator and fitting
With greatly keep certain safe distance.Cross-arm employed in overhead distribution is iron cross arm at present, in distribution line
In belong to grounding body, there is no defect that can say when power distribution network operates normally, but when route or lead loosen, take, fall in cross
Problem just highlights when in load, since iron cross arm itself is conductor, route is caused to be grounded, and route once connects
Line outage, staff must be carried out fault inspection, both influence power supply reliability in this way by ground, few power supply volume, and give work
Workload is increased as personnel.Currently due to factors such as natural calamity and construction technologies, so that such failure is in power distribution network
It is commonplace.And how can be avoided or reduce the generation of such failure, it to inquire into and solve the problems, such as jointly at us.
Summary of the invention
The purpose of this utility model is to provide for that a kind of structure is simple, at low cost, the overhead distribution cross-arm of insulation.
The technical solution of the utility model is:
JKTYJ overhead distribution insulator crossarm includes cross-arm main body, and the cross-arm main body is angle shape, institute
It states cross-arm body outer surface and seals up the semi-conductive layer that a layer thickness is 1.5mm, one layer is sealed up outside semi-conductive layer
Thickness is not less than the crosslinked polyetylene insulated oversheath of 5.5mm, cross-arm main body to be provided with uniform crosslinked polyethylene on one side exhausted
Emargination slot is driveed on one side with crosslinked polyetylene insulated groove there are four hole, and the both ends of cross-arm main body are arranged in two of them hole,
Other two apertures are respectively 30cm with two end hole distances, another face central point two sides of cross-arm are respectively provided with a strip-shaped hole, horizontal
Carry on a shoulder pole two inverted V-shaped parallels for having certain distance between two strip-shaped holes of main body equipped with centre.
The beneficial effects of the utility model are:
The utility model processing and manufacturing is simple, is easily installed use, for the cross of iron used by current overhead distribution
Load, fall off in conducting wire, lead leads to the needs of ground connection and short circuit on iron cross arm, proposes a JKTYJ overhead distribution
Insulator crossarm, solving the problems, such as to fall in after loosening because of conducting wire, lead leads to line-to-ground on iron cross arm.Guarantee system is stablized
Property, power supply reliability is improved, hotline maintenance is convenient for, is used manpower and material resources sparingly.Multiple grooves are equipped in the one side of cross-arm main body, it can be with
Prevent the live wire fallen from sliding.
Detailed description of the invention
Fig. 1 is the application overall structure diagram.
Fig. 2 is another angled arrangement schematic diagram of the application.
Fig. 3 is the application cross-arm cross-section diagram.
Specific embodiment
For foregoing is directed to the defect arrived, a kind of JKTYJ overhead distribution insulator crossarm of the applicant's innovation and creation.
The application is described in detail with reference to the accompanying drawing:
JKTYJ(JK is aerial, T iron core, and YJ is crosslinked polyetylene insulated) overhead distribution insulator crossarm includes cross-arm main body
1, the cross-arm main body 1 is angle shape, and the semi-conductive layer 2 that a layer thickness is 1.5mm is sealed up in 1 outer surface of cross-arm main body,
A layer thickness is sealed up outside semi-conductive layer 2 not less than the crosslinked polyetylene insulated oversheath 3 of 5.5mm, in the one side of cross-arm main body 1
It is provided with uniform crosslinked polyetylene insulated groove 4, to guarantee to slide after live wire falls into cross-arm.With fluted 4
Drive on one side there are four hole 5, for installing insulator, two of them hole is arranged in the both ends of cross-arm main body 1, other two apertures respectively with
Two end hole distances are 30cm.Another face central point two sides of cross-arm are respectively provided with a strip-shaped hole 6, and two strip-shaped holes are for cross-arm
Used in installation is connect when fixed with anchor ear.6 distance of strip-shaped hole is determined according to the installation site of cross-arm, in cross-arm main body 1
It is installed between two strip-shaped holes 6 there are two there is the inverted V-shaped parallels 7 of certain distance, is installed after cross-arm to guarantee its horizontal direction not
It distorts and keeps horizontal.
The above is specific embodiment of the utility model and the technical principle used, any to be based on the utility model
Equivalent transformation on the basis of technical solution, belongs within the protection scope of the utility model.
