Abstract
Provided is a composite cross-arm insulator for the 35 kV power distribution in a rural power grid. The composite cross-arm insulator includes a fitting at the bottom, a core rod, umbrella skirt sheaths and a wire binding duct at the top. The fitting is provided with a connection hole in the middle thereof. The multiple umbrella skirt sheaths are axially disposed on the core rod side by side. The core rod is an epoxy glass steel core round bar. Two ends of the core rod respectively are solidified with the wire binding duct and the fitting to form a whole. A vulcanized silicone rubber layer is solidified outside the fitting, the core rod, the umbrella skirt sheaths and the wire binding duct. According to the composite cross-arm insulator, the strength and the insulating property of the composite cross-arm insulator are enhanced, and thus the service life thereof is prolonged, and the reliability and safety performance of the operation of lines are improved.
Description
Technical field
The utility model relates to a kind of composite isolated cross-arm structure that rural power grids 35kV lightness track remodelling is used that is applicable to.
Background technology
Insulator is for supporting the insulator of wire.Cross arm insulator is for fixed cable, and requirement can be born the loading of wire vertical direction and the pulling force of horizontal direction.In long-term use procedure, insulator will stand wind, drenches with rain, Exposure to Sunlight, and the erosion of the various materials of nature, so the quality of its performance is very important factor to the safe operation of circuit, has directly determined safety and the useful life of circuit.Composite cross-arm insulator, as line insulator of new generation, grows with each passing day with the use amount in its excellent performance ， China electrical network, brings very large benefit to the safe operation of electric power system.But in the process of operation, also there are many problems in existing cross arm insulator.Because the top of traditional cross arm insulator connects the bundling trough design problem of gold utensil, easily fracture, and easily wire is caused to wearing and tearing after long-time running, causes conductor overheating and causes security incident.
Summary of the invention
Technical problem to be solved in the utility model is just to provide a kind of raising serviceability, guarantees safe operation, the composite cross-arm insulator that the rural power grids 35kV distribution circuit that mechanical strength is high is used.
Above-mentioned purpose of the present utility model is achieved through the following technical solutions.
A kind of rural power grids 35kV distribution circuit composite cross-arm insulator.It comprises the bundling trough at gold utensil, plug, umbrella sheath and the top of bottom.Described gold utensil is middle with connecting hole; Several umbrella sheaths be arranged in parallel vertically on plug.Plug is expoxy glass steel core pole, and plug two ends are solidified into one with bundling trough and gold utensil respectively; At gold utensil, plug, umbrella sheath and bundling trough, be solidified with sulphurated siliastic layer outward.
The radius of bundling trough 4 is 16mm, and length is 70mm.
The utility model has the advantage of: increased intensity and the insulation property of composite cross-arm insulator, increased its useful life.Because the utility model has increased the contact area of wire and bundling trough, circuit reliability of operation and fail safe have been improved.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model insulator crossarm.
In figure: the 1st, gold utensil, the 2nd, plug, the 3rd, umbrella sheath, the 4th, bundling trough, the 5th, sulphurated siliastic layer.
Embodiment
Below in conjunction with Fig. 1, introduce in detail the utility model composite cross-arm insulator structure:
The utility model relates to a kind of rural power grids 35kV distribution circuit composite cross-arm insulator.It comprises the bundling trough 4 at gold utensil 1, plug 2, umbrella sheath 3 and the top of bottom.Described gold utensil 1 is middle with connecting hole; Several umbrella sheaths 3 be arranged in parallel vertically on plug 2.Plug 2 is expoxy glass steel core poles, and plug 2 two ends are solidified into one with bundling trough 4 and gold utensil 1 by crimping mode respectively; Then in mould, integral body is solidified by high-temperature silicon disulfide rubber, at gold utensil 1, plug 2, umbrella sheath 3 and the outer generation sulphurated siliastic of bundling trough 4 layer 5.This structure bonding strength is high, and electric property is excellent, meets electric property and the mechanical test standard-required of composite cross-arm insulator completely.Another feature of this composite cross-arm insulator is: the radius of bundling trough 4 is 16mm, and length is 70mm.Compare with the bundling trough size at traditional cross arm insulator top, increased the contact area of wire and bundling trough, improved circuit reliability of operation and fail safe.
