Abstract
The utility model relates to an anti-tension composite insulator which is used for a distribution line of high voltage of 10KV. The utility model is composed of a hardware 1, a core rod 2 and a skirt sleeve 3. The end part of the hardware 1 is a plate shape, and the plate is provided with a connecting hole 4. The skirt sleeve 3 is provided with a sleeve 5 and an umbrella skirt 6, and the whole bodies of the sleeve 5 and the umbrella skirt 6 are assembled on the core rod 2 by adopting the injection molding. Both ends of the core rod 2 are provided with connecting heads 7 which are connected with the hardware 1. The utility model has the advantages of light weight, convenient installation, difficult damage and reliable operation. The utility model can meet the requirement of the mechanical insulating performance and the electrical insulating performance of the distribution line of 10KV.
Description
The utility model and high-tension distributing line are relevant with the strain insulator composite insulator, and especially the strain insulator composite insulator that is shaped with integral molded plastic that the 10KV high-tension distributing line is used is relevant.
Traditional high voltage circuit has high-strength plug with the strain insulator composite insulator.Silicone rubber jacket is arranged on the plug, is on the automatic coating machine of special use silicon rubber to be extruded on the plug, and through high temperature, high pressure sulfuration, a seamless overcoat that on plug, forms.The silicon rubber full skirt is made by mould pressing method, then manufactured goods is installed by predetermined spacing, is fixed to the mandrel surface of band sheath by chemical bond.The manufacturing process complexity, the manufacturing cost height.The gold utensil one at traditional strain insulator composite insulator two ends is the metal knob, and one is the fixed cover that cooperates with the metal knob, complex structure, manufacturing cost height.
The purpose of this utility model provides a kind of simple in structure, and manufacturing process is simple, and is in light weight, and the intensity height is easy for installation, the special-purpose strain insulator composite insulator of 10KV safe and reliable to operation.The utility model is by gold utensil 1, and plug 2, skirt overlap 3 and form.Gold utensil 1 end is a plate shape, and connection holes 4 is arranged on the plate.Skirt cover 3 has cover 5 and full skirt 6, and both integral molded plastics are on plug 2.Plug 2 two ends have connector 7 to be connected with gold utensil 1.
Cover 8 is arranged on the connector 7 of the present utility model, and overlapping 8 outer surfaces has screw thread to cooperate with the blind threaded of gold utensil 1.Connector 7 has caulking groove, and chock 10 is positioned at caulking groove, and its end holds out against the bottom of blind hole.
Skirt cover 3 of the present utility model is shaped for the organic silicon rubber integral molded plastic.The less full skirt of the bigger full skirt of three diameters and two diameters is arranged alternately.
The utility model adopts integral molded plastic technology once-forming, and simple in structure, easy to manufacture, in light weight, cost is low, the intensity height, and cracky is not safe and reliable to operation.Simplified the connection gold utensil, installed very convenient.High strength insulation mandrel and organic silicon rubber skirt are locked fixed for one, and the two ends gold utensil that very is connected and fixed securely can satisfy 10KV distribution line machinery and electrical insulation properties requirement.Tensile strength is greater than 40KN, and the power frequency dry flashover voltage is greater than 75KV, and the lightning impulse flashover voltage is greater than 125KV (amplitude), and power frequency shows flashover voltage greater than 40KV.Reveal distance greater than 350cm.Umbrella directly is φ 70～φ 85mm, and overall weight is not more than 2.0kg.
Fig. 1 is a front view of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is the vertical view of plug.
Following is embodiment of the present utility model:
Plug 2 adopts galss fiber reinforced resin to draw and dials rod, has good insulation performance and high mechanical strength.Plug length is 18mm for the 290mm diameter.
Integral molded plastic shaping skirt cover 3 on the organic silicon rubber plug in mould.The length 220mm of skirt cover 3, the diameter of cover is 26mm, and the diameter of little full skirt is 70mm, and the diameter of big full skirt is 85mm, and two full skirt spacings are 55mm, and full skirt is five, and three big two is little.Connecting the aperture on the gold utensil is 16mm.
