Problems solved by technology

When dry-type transformers are used, they need to be cooled. The common forced air cooling is mostly used in the case of excessive load operation. Generally, an external power supply is required to control the operation. Not only is it not convenient to use, but also the cost is relatively high.
However, the ventilation volume of natural air cooling cannot meet the actual cooling demand, especially in the hot summer or in the case of long-term operation, the temperature around the dry-type transformer is too high, and there is a case of burning, resulting in damage to the dry-type transformer and affecting the power distribution schedule , the safety performance used is too low, it is difficult to meet the actual use requirements

Abstract

The invention relates to the technical field of dry-type transformers, and discloses a dry-type transformer with high safety performance, which comprises a cooling mechanism, and the cooling mechanism comprises a small turntable; according to the distance between the heat conduction block and a heat source, low-boiling-point evaporated liquor in the heat conduction block is converted between vaporization and liquefaction, the large rotating disc rotates, the heat absorption belt synchronously rotates, heat generated by operation of the dry-type transformer is absorbed and transferred, external energy is not needed, energy conservation and environmental protection are achieved, it is guaranteed that the dry-type transformer can be continuously and normally used, and the possibility of burnout is reduced; a small rotating disc drives a rotating column to rotate, a rotating rod set drives a piston to move up and down in the vertical direction, the movement of the piston changes the space in an exhaust pipe, generated airflow accelerates air flow in the exhaust pipe and takes away heat adsorbed on the surface of a heat absorption belt, the effect of cooling the exhaust pipe is achieved, and circulating heat absorption of the exhaust pipe is facilitated; heat dissipation can be continuously carried out on the dry-type transformer, and normal operation of the dry-type transformer is facilitated.

Description

technical field [0001] The invention relates to the technical field of dry-type transformers, in particular to a dry-type transformer with high safety performance. Background technique [0002] Dry-type transformers are of great significance to power grid construction, and are now widely used in local lighting, high-rise buildings, airports and other places. When dry-type transformers are used, they need to be cooled. The common forced air cooling is mostly used in the case of excessive load operation. Generally, an external power supply is required to control the operation. Not only is it not convenient to use, but also the cost is relatively high. However, the ventilation volume of natural air cooling cannot meet the actual cooling demand, especially in the hot summer or in the case of long-term operation, the temperature around the dry-type transformer is too high, and there is a case of burning, resulting in damage to the dry-type transformer and affecting the power dist...
