Abstract
The utility model relates to an H level environment protecting type ceramic insulation dry type electric power transformer which comprises an iron core, a low voltage coil and a high voltage coil. The utility model has the technical scheme that an insulating cylinder is installed outside the high voltage coil and closes the high voltage coil, thereby, the utility model effectively reaches the effects of dust prevention, damp prevention and insect prevention. Partial insulating members in the utility model are made from high frequency ceramic (high voltage electric ceramic), and then, the utility model not only solves the environmental protection problem caused by organic insulating materials, but also enhances the fireproof performance, the humidity resistance and safety performance in operation of the dry type transformer.
Description
Technical field
The utility model is a kind of H level environment-friendly ceramic insulated dry power transformer.
Background technology
At present, dry-type transformer is divided into dipping air insulation dry-type power transformer and resin-insulated dry power transformer by its manufacturing process, present better performances be new-type class H insulation impregnating dry-type power transformer---open-ventilating dry-type transformer.But the line cake that the high-voltage line of this transformer closes is exposed in the air, adheres to dust easily, and has insect and toy to invade unavoidably, can cause certain damage to the insulation of transformer.
Summary of the invention
The purpose of this utility model is: design a kind of H level environment-friendly ceramic insulated dry power transformer with dustproof, protection against the tide and vermins-proof effect.
The utility model comprises iron core, low-voltage coil and high-tension coil, and its technical scheme is: insulating cylinder is housed outside high-tension coil.This insulating cylinder in the high-tension coil outside with its sealing, thereby reach dustproof, protection against the tide and vermins-proof effect effectively.Wherein, the installation of insulating cylinder may realize by connector, also can with its up and down two ends cooperate with insulating end ring assemble after, fix by briquetting.And the insulating end ring place is provided with safety valve.Cushion pad preferably is housed between insulating cylinder and the briquetting.The folder that it is played pressuring action is housed on the briquetting.
In addition, above-mentioned insulating cylinder can be an overall structure, or is made of two or more arcs, connects by bindiny mechanism between the arc.

Fig. 1 is the cutaway view of the utility model embodiment;
Wherein, 1, insulator, 2, iron core, 3, folder, 4, briquetting, 5, cushion pad, 6, insulating end ring, 7, low-voltage coil, 8, insulating cylinder, 9, high-tension coil, 10, stay, 11, cushion block, 12, insulating cylinder.
Embodiment
As shown in the figure, present embodiment comprises base and is installed in iron core 2 on the base, be enclosed within unshakable in one's determination 2 outer be low-voltage coil 7, low-voltage coil 7 is outer to be with an insulating cylinder 8, is stained with stay 10 (or insulating cylinder 8 is made into integration with stay 10) on the insulating cylinder 8.High-tension coil 9 directly on stay 10, separates with cushion block 11 between its line cake.Insulating cylinder 12 is housed outside high-tension coil 9, and it cooperates with insulating end ring 6 with high-tension coil 9 two ends, and insulating end ring 6 places are provided with safety valve.Between iron core 2, low-voltage coil 7, insulating cylinder 8, high-tension coil 9 and insulating cylinder 12, certain insulation distance is arranged all, and descend two ends to place cushion pad 5 and briquetting 4 thereon, be fixed and clamped by folder 3 at last.And high-low pressure lead-in wire is fixed on the insulator 1 on the folder 3.
SI semi-insulation spare in the utility model, as: insulating cylinder, stay, cushion block, insulating end ring, briquetting and being fixed on is used for supporting the insulator of high-low pressure lead-in wire on the folder, its material adopts high frequency porcelain (or high tension insulator), with other material (as epoxy resin, organic insulating materials such as diphenyl ether) compare, the utlity model has excellent dielectric properties and mechanical performance, and it is little with the rising variation of temperature with temperature ε and tan δ, its heat resistance can reach more than 650 ℃, considerably beyond the temperature requirement of 180 ℃ of H class F insulations, and the heat that can be in time coil be produced shed, thereby guaranteed the reliability of long-time running.Adopt high frequency porcelain or high tension insulator, both solved the environmental issue that organic insulating material caused, also improved fire protecting performance and the humidity resistance and the operating security performance of dry-type transformer greatly.
