High overload capacity distribution transformer

Abstract

The invention discloses a high overload capacity distribution transformer. The high overload capacity distribution transformer is characterized by comprising a transformer core (1), an F-grade insulation grade winding (2), high-fire-point transformer oil (3), a transformer tank (4) and a transformer accessory (5), wherein the transformer core (1) and the F-grade insulation grade winding (2) form an F-grade insulation grade transformer body, the transformer core (1) serves as the magnetic circuit portion of the transformer, the F-grade insulation grade winding (2) is arranged outside the transformer core (1), the F-grade insulation grade winding (2) comprises low-voltage coils and high-voltage coils arranged outside the low-voltage coils, and the F-grade insulation grade winding (2) serves as the circuit portion of the transformer. The high overload capacity distribution transformer is particularly suitable for being used for the conditions of large in short-time power utilization load, the power utilization quality can be improved, transformer accidents can be reduced, the service life of the transformer can be prolonged, the high overload capacity distribution transformer has the advantages that the structure is novel and reasonable, the performance is reliable, and the high overload capacity distribution transformer is particularly suitable for power supply of rural areas.

Description

Technical field [0001] The invention relates to a transformer, in particular to a high overload capacity distribution transformer. Background technique [0002] With the development of the country, the electricity load has increased sharply, especially during the peak hours of electricity consumption, the transformer often runs overloaded, which not only shortens the service life of the transformer, but also burns the transformer and causes greater fire hazards. If the capacity of the transformer is increased, the no-load loss of the transformer will increase, because the no-load loss will always exist as long as the transformer is connected to the network, which not only increases the initial investment cost, but also increases the electricity cost and wastes energy when the electricity is low. Summary of the invention [0003] In view of the shortcomings in the prior art, the purpose of the present invention is to provide a high overload capacity distribution transformer that ca...
