Oil-immersed on-load voltage regulation power transformer

Abstract

The invention discloses an oil-immersed on-load voltage regulation power transformer which comprises a support rack, a tank body, a water conveying pipeline and a heat radiation device, wherein coilsare uniformly arranged inside the tank body; an oil storage tank is mounted on one side of the top of the tank body; an oil conveying pipeline is connected with the bottom of the oil storage tank; oneend of the oil conveying pipeline is connected with the coils and extends outside the tank body; a controller is mounted on one side of the tank body below the oil storage tank; a thin metal piece isarranged on side surfaces of the coils inside the tank body; fins are uniformly connected with one sides of the thin metal pieces; a vacuum plate is arranged at the top end inside the tank body; anda temperature sensor is mounted at one end of the vacuum plate inside the tank body. As a heat blocking layer is arranged at the top of the vacuum plate, sound absorption cotton is uniformly arrangedinside the vacuum plate below the heat blocking layer, and grooves are uniformly formed in the bottom of the vacuum plate, noise can be conveniently collected, a certain silencing effect can be achieved, and noise pollution can be reduced.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to an oil-immersed on-load voltage regulating power transformer. Background technique [0002] There is a problem of heat dissipation in the use of substations. At present, the structure of ventilation windows is used for heat dissipation. However, such a structure cannot quickly and effectively dissipate heat. Especially in high temperature weather, the heat dissipation problem is more serious, which is not conducive to life and production. [0003] Although this kind of roof cooling type box-type transformer room has compact structure, convenient installation, low operating cost, low coil temperature rise, strong overload capacity, and firm structure, however, some oil-immersed power transformer rooms are installed outdoors. Yes, in a high temperature environment and under strong sunlight, due to the limited heat dissipation capacity of the bellows, it may generate heat due t...

[0002] There is a problem of heat dissipation in the use of substations. At present, the structure of ventilation windows is used for heat dissipation. However, such a structure cannot quickly and effectively dissipate heat. Especially in high temperature weather, the heat dissipation problem is more serious, which is not conducive to life and production.

[0003] Although this kind of roof cooling type box-type transformer room has compact structure, convenient installation, low operating cost, low coil temperature rise, strong overload capacity, and firm structure, however, some oil-immersed power transformer rooms are installed outdoors. Yes, under high-temperature environment and strong sunlight, due to the limited heat dissipation capacity of the bellows, it may generate heat due to light. Therefore, the heat dissipation function of oil-immersed power transformers in high-temperature environments is greatly reduced
