Description

Technical Field

[0001] The utility model relates to the technical field related to transformer temperature control, in particular to a temperature control installation structure for a box-type dry-type transformer, and also to a prefabricated transformer station shell. Background Art

[0002] A temperature controller is typically located on top of the dry-type transformer housing. This controller works in conjunction with a temperature sensor. The temperature sensor measures the internal temperature of the dry-type transformer using a probe or other method, then transmits the temperature signal to the temperature controller. The controller then controls the transformer according to the preset setpoint, adjusting the transformer's load and operating status to prevent overheating and other problems caused by overload.

[0003] Currently, transformers usually have their own temperature controller, which is usually installed on a bracket on the side of the transformer body. In the environment where the internal space of the prefabricated substation shell is relatively small and the direction of the transformer installed in the prefabricated substation shell is uncertain, the display direction of the thermostat on the transformer is not fixed, which will cause inconvenience to the temperature collection, inspection, calibration and maintenance of the thermostat in the later stage.
