Description
Technical field
This utility model relates to a kind of combined insulated dry voltage transformer making electric energy metrical, measurement and protection use in power system.
Background technology
At present, dry-type voltage inductor product is casting insulated based on virgin resin, and this kind of product there is problems in that 1) secondary repair after, outward appearance easily deposits defect；2) in high-voltage leading-out wire position because electric field is concentrated and the too high partial discharge quantity that is easily generated of field intensity exceeds standard；3) without overcurrent protection measure, easily there is the damage of transformer body.
Summary of the invention
The purpose of this utility model is in that to provide a kind of combined insulated dry voltage transformer with fuse protection, and it is because repairing without secondary, outward appearance zero defect；It is provided with special shielding part in high-voltage leading-out wire position, makes the partial discharge quantity of product meet Standard；Protect with fuse, can ensure that transformer body is not damaged；Anti-filthy ability is strong.
This utility model solves its technical problem and be the technical scheme is that it is made up of high-voltage leading-out wire, fuse, shielding part, device body, resin insulating barrier, silicone rubber insulation layer；The built-in fuse of bushing, fuse and high-voltage leading-out wire junction set a cylindrical shield shield, shielding part is made by wire netting, shielding part, high-voltage leading-out wire, device body are poured into a mould by mixture of epoxy resins under vacuum, forming resin insulating barrier, resin insulating barrier paste outside silicone rubber insulation layer forms combined insulated dry structure.
The purpose of this utility model realizes further also by following technical proposals.
Silicone rubber insulation layer is provided with 17 layers of alternate full skirt of large and small umbrella.
The beneficial effects of the utility model are: the combined insulated dry structure that resin insulating barrier paste outside silicone rubber insulation layer is formed, it is not necessary to secondary is repaired, outward appearance zero defect.Fuse and high-voltage leading-out wire junction set a cylindrical shield shield, solve the problem that electric field is concentrated and field intensity is too high herein, make product shelf depreciation meet Standard.The built-in fuse of bushing, occur overcurrent time, can instantaneous trip system power supply, to ensure that transformer body is not damaged.Silicone rubber insulation layer is provided with 17 layers of alternate full skirt of large and small umbrella, improves the anti-filthy ability of product.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further illustrated.
Fig. 1 is front view of the present utility model.
1. umbrella in figure, 2. resin insulating barrier, 3. silicone rubber insulation layer, 4. fuse, 5. shielding part, 6. high-voltage leading-out wire, 7. device body.
