Cooling device for protection of box-type transformer

Abstract

The invention provides a cooling device for protection of a box-type transformer. The upper end of a bottom plate is provided with four protection plates, four protection plates are arranged in perpendicular to the bottom plate, the bottom plate and the protection plates are connected via hinges, the four protection plates are connected via buckles, fan holes are formed on the protection plates arranged on a front side end surface and a rear side end surface of the bottom plate, a temperature sensor is fixed at the middle position of the bottom plate, through holes are distributed on the protection plates, rotation blades are connected with a driving motor, the driving motor is arranged at the middle position of the fan holes, the temperature sensor is in one-way and electrical connection with a singlechip, the singlechip is in one-way and electrical connection with a relay, and the relay is in one-way and electrical connection with the driving motor. With the additional arrangement of the buckles and the hinges, the protection plates and the bottom plate are fixed and separated; with the design of the through holes, airflow circulation is convenient; and with the arrangement of the rotation blades, heat in the protection plates can be effectively dissipated.

Description

technical field [0001] The invention relates to a box-type transformer protection and heat dissipation device, which belongs to the field of power supply devices. Background technique [0002] In the prior art, almost all 10kV box-type distribution transformers use forced ventilation, but the ventilation channel is narrow and the circulation air channel is not smooth. Box-type distribution transformers are often overheated, and the temperature control protection device will trip the switch, causing a large area of ​​power outages during peak power consumption, reducing electricity sales, and reducing power supply reliability; increasing the workload of emergency repair and operation personnel, but the general The heat dissipation device for transformer protection adopts an all-weather heat dissipation method. This type of heat dissipation has the problem of large energy loss, so a box-type transformer protection heat dissipation device is continued to solve the problems ment...

Problems solved by technology

Box-type distribution transformers are often overheated, and the temperature control protection device will trip the switch, causing a large area of ​​power outages during peak power consumption, reducing electricity sales, and reducing power supply reliability; increasing the workload of emergency repair and operation personnel, but the general The heat dissipation device for transformer protection adopts an all-weather heat dissipation method. This type of heat dissipation has the problem of large energy loss, so a box-type transformer protection heat dissipation device is continued to solve the problems mentioned in the above background.
