On-load capacity-adjusting transformer good in heat dissipation and convenient to control

Abstract

The invention discloses an on-load capacity-adjusting transformer good in heat dissipation and convenient to control. The on-load capacity-adjusting transformer comprises a transformer body and an on-load capacity-adjusting switch, wherein a plurality of wire outgoing posts are arranged at the upper end of the transformer body; the on-load capacity-adjusting switch is mounted on the transformer body; an on-load capacity-adjusting controller is mounted on the on-load capacity-adjusting switch; the on-load capacity-adjusting controller is connected with the on-load capacity-adjusting switch; a base is further arranged at the bottom of the transformer body; blast pipes are arranged inside the base; one end of each blast pipe is communicated with the inner cavity of the transformer body, and the other end of the blast pipe is communicated with the outside; a blast fan is arranged inside a port, communicated with the outside, in the blast pipe; an exhaust fan communicated with the inner cavity of the transformer body is further arranged on the side wall of the transformer body; a plurality of blast pipes are uniformly arranged inside the base at intervals. The on-load capacity-adjusting transformer has a good heat-dissipating effect, so that an electrical element inside the on-load capacity-adjusting transformer is guaranteed to be in a normal working environment, and the service life of the on-load capacity-adjusting transformer is prolonged.

Description

technical field [0001] The invention relates to the technical field of power equipment, in particular to an on-load capacity regulating transformer with good heat dissipation and easy manipulation. Background technique [0002] Transformer is an important power transmission and distribution equipment, which plays an irreplaceable role in power transmission and distribution lines. The load on the transmission and distribution line is highly unbalanced in time. If the capacity of the transformer is designed according to the maximum power load, it will cause a lot of no-load loss and resistance loss when the power consumption is low, which seriously violates the national policy of energy saving and emission reduction. If the capacity of the transformer is designed according to the normal power load, there will be serious hidden dangers in power consumption during peak power consumption. For this reason, capacity-adjusting transformers have appeared on the market. [0003] Th...

AI Technical Summary

Problems solved by technology

Existing on-load capacity regulating transformers generally use ventilation holes on the transformer to dissipate heat, and the heat dissipation effect is not good. If the internal electrical components of the on-load capacity-regulating transformer are in a high-temperature working environment for a long time, the performance of the on-load capacity-regulating transformer will be seriously affected. In addition, the existing on-load capacity regulating transformer is inconvenient to use. When manual capacity adjustment is required, it generally requires staff to arrive at the scene and adjust it through the control panel on the on-load capacity regulating transformer, which is not convenient enough.
