Abstract
The utility model relates to an electric locomotive composite insulator comprising a porcelain cylinder, a high-temperature adhesive, metal inserts and an enamel layer. The porcelain cylinder has a wavy structure. The upper end and the lower end of the porcelain cylinder are provided with a blind hole for installing a metal insert respectively. The outer surface of the porcelain cylinder having a wavy structure is provided with the enamel layer. Each metal insert has a T-shaped structure provided with a central threaded hole, that is the upper end surface of the metal insert having a T-shaped structure is a hexagonal end surface, the central portion of the metal insert is provided with a threaded hole, and the two metal inserts having a T-shaped structure are bonded into the blind holes in the upper end and the lower end of the porcelain cylinder through high-temperature adhesive separately. The high temperature resistance value of the high-temperature adhesive is not less than 250 DEG C. The structure of the utility model has the advantage of good universality, and can be used to well solve the high temperature resistance, high voltage resistance, waterproof performance and long service life requirements on the insulator in complex locomotive operating environments.
Description
Technical field
The utility model relates to a kind of insulator, particularly a kind of use for electric locomotive composite insulator.
Background technology
At present, insulator for electric locomotive mostly is pottery, mica ceramics or epoxide resin material.These material properties are more single, respectively have deficiency: its pottery has certain water absorption rate, the easy conducting of sleety weather; Mica ceramics is easy aging and intensity is not high; Epoxy resin non-refractory.That existing insulator can not meet is simultaneously high pressure resistant under the complicated running environment of locomotive, the requirement of high temperature, waterproof, long service life.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned defect, provide a kind of simple in structure, high temperature resistant, high pressure,
The use for electric locomotive composite insulator of the good and long service life of versatility.
The technical solution of the utility model: a kind of use for electric locomotive composite insulator, is characterized in that this described composite insulator comprises porcelain knob body, high temperature adhesive, metal insert and glaze layer;
Described porcelain knob body profile is wavy structure, and porcelain knob body upper/lower terminal has the blind hole that metal insert is installed; The porcelain knob external surface of this wavy structure is provided with glaze layer;
Centered by described metal insert, open the T shape structure of screwed hole, the metal insert upper surface of this T shape structure is hexagon end face, center has screwed hole, and the metal insert of two T shape structures is adhesive in respectively in the blind hole of porcelain knob body upper/lower terminal by high temperature adhesive.The high temperature resistant value of described high temperature adhesive is not less than 250 DEG C.
Porcelain knob body two ends perforate in the utility model, metal insert passes through high temperature adhesive mucilage binding in porcelain knob body two ends; Porcelain knob body profile is wavy structure, increases its creepage distance, has improved to a great extent the class of insulation of insulator.The glazing of porcelain knob surface; Porcelain knob body itself has very strong insulation property, and the glazing of porcelain knob surface can be played the effect of waterproof; High temperature adhesive ability is not less than 250 DEG C of high temperature, and bonding force is strong, and does not absorb water; Metal insert can, according to the different machining screw sizes that require, can play well universal;
In sum, structure of the present utility model has good versatility, and can solve under the complicated running environment of locomotive the requirement of high temperature resistant, high pressure to insulator, waterproof, long service life.
