Abstract

The invention relates to the technical field of transformer equipment, particularly to a novel dry-type transformer. The novel dry-type transformer comprises a coil winding, an upper fixing piece and a lower fixing part; the upper fixing piece and the lower fixing part are used for fixing the coil winding; the coil winding comprises an iron core, a low-voltage coil and a high-voltage coil, at least one longitudinal ventilation air passage is arranged between the low-voltage coil and the high-voltage coil, and an automatic temperature controller with a CPU (central processing unit) interface is arranged on the iron core. According to the novel dry-type transformer adopting the structure, firstly the at least one ventilation air passage is adopted for ventilation and heat dissipation, the heat dissipation effect is good, forced air cooling is not needed, and safe operation can be ensured under 120% load during peak hours; then the automatic temperature controller with the CPU interface is adopted to automatically control the operating temperature of the transformer, and the operating condition of the transformer can be remotely monitored through a network after the transformer is connected with a computer through the CPU interface, thus reaching the purposes of intelligent control and real-time monitoring.

Description
