Abstract
The utility model belongs to the improvement of an insulation structure and provides an insulation structure which is formed by an insulator fixed on a shoe plate, wherein the shoe plate is an insulation connector and is an integrated body with the insulator. According to the utility model, the insulation connector is used as the shoe plate for fixing the insulator to make the insulator and the insulation connector become a whole insulation part and thereby to increase a skirt board length of the insulator and to increase more than two insulation grades.
Description
Technical field
The utility model belongs to a kind of improvement of insulation system.
Background technology
Current, the insulation device of electric power power transmission and transformation industry is mostly continued to use in the insulation of domestic industrial dedusting and oil smoke of catering industry cleaning equipment high voltage appearance components and parts.Be " insulator " commonly used on transformer and the power transmission line, also claim porcelain vase.The service condition of this type insulation device is mostly based on normal temperature, and normal wet, medium is an air, if it is inserted in the big closed environment of high temperature (t >=70 ℃), high dust or oil mist concentration, its insulating capacity will be had a greatly reduced quality.Like the porcelain vase that a technical parameter is withstand voltage 30KV, use it for the transformer connection end, working life can reach 15 years, and it is installed in cooking fume remover inside, then insulation damages just possibly occur less than three months, is commonly called as the phenomenon of " creepage ".This is that the composition of incrustation is very complicated, but mostly belongs to electric conductor, therefore in hyperbaric environment, very easily forms bridge circuit, " creepage " phenomenon occurs because a large amount of oil mist particles under 8 ~ 15m/s wind speed and hot and humid effect, forms incrustation on the porcelain vase surface.
Summary of the invention
The purpose of the utility model is to provide a kind of insulation system, and it can overcome above-mentioned " creepage " phenomenon, and prolongs the useful life of insulation device under special environment.
The technical scheme that realizes the utility model is: a kind of insulation system, constitute by the insulator that is fixed on the supporting bracket, wherein, supporting bracket is the insulation connector, and with insulator be one.
And insulator is provided with the U-shaped support of being with through hole with insulation connector periphery.
And, U-shaped support ground connection or high-voltage power cathode.
The utlity model has following advantage:
1, will insulate connector as the sub supporting bracket of fixed insulation, and make insulator and insulation connector become whole insulating part, thereby increase the shirt rim length of insulator, promote the class of insulation more than 2.
2, the U-shaped support has intercepted oil mist particles incrustation on insulator, thereby has overcome " creepage " phenomenon, has prolonged the useful life of insulating part, has significantly promoted the class of insulation.
Description of drawings
Fig. 1 is the structure chart of the utility model.
Wherein, 1, insulator, 2, the insulation connector, 3, counterbore, 4, the U-shaped support, 5, through hole, 6, guide rod, 7, battery lead plate.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
The scheme that the utility model provides is, a kind of insulation system is as shown in Figure 1, is made up of the insulator 1 that is fixed on the supporting bracket, and wherein, supporting bracket is an insulation connector 2, and with insulator 1 be one.
U-shaped support 4 ground connection or high-voltage power cathode.
Visible by Fig. 1, the direction of arrow is represented the direction of motion of flue gas, perpendicular to the flue gas direction metal guide rod 6 is set in the flue, and guide rod 6 first-class fixed distance multi-disc battery lead plate 7, and insert respectively in the counterbore 3 of insulator 1 at the two ends of guide rod 6.Have insulation connector 2 to connect and compose insulating part between the insulator 1, insulation connector 2 can be one-body molded with insulator 1.This shows; The utility model utilization insulation connector 2 has increased the shirt rim length of insulator 1; Deadened effectively " creepage " that insulating part causes because of incrustation; Make the class of insulation from bringing up to more than the 50KV below traditional 20KV, guaranteed the fail safe of insulating part in abominable environments for use such as fume purifying.
In addition, also visible by Fig. 1, U-shaped support 4 wraps up insulator 1 and insulation connector 2, effectively insulating part and exhaust gases passes is kept apart, and has blocked the deposition of oil mist particles on the insulating part surface.U-shaped support 4 is provided with through hole 5 above insulator 1, fix for guide rod 6 stretches into insulator 1.Therefore, have a small amount of oil mist particles and pass the inner chamber that through hole 5 gets between insulating part and the U-shaped support 4.Because the positive pole of U-shaped support 4 ground connection or high voltage source, the electronegative oil mist particles that gets into inner chamber will be adsorbed in the inboard of U-shaped support 4, thereby avoids oil mist particles incrustation on insulating part, the useful life of significantly having improved insulation effect and insulating part.
Claims (3)
1. an insulation system is made up of the insulator that is fixed on the supporting bracket, it is characterized in that: supporting bracket be the insulation connector, and with insulator be one.
2. a kind of insulation system according to claim 1 is characterized in that: insulator is provided with the U-shaped support of being with through hole with insulation connector periphery.
