Description

Technical Field

[0001] The utility model relates to the field of products related to transformer substations, in particular to cooling equipment used in box-type transformer substations. Background Art

[0002] The box-type substation is a factory-prefabricated indoor and outdoor compact distribution equipment that integrates high-voltage switchgear, distribution transformers and low-voltage distribution devices according to a certain wiring scheme. It combines the functions of transformer step-down and low-voltage distribution organically and is installed in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, anti-theft, heat-insulated, fully enclosed and movable structural box. The shell of the box-type substation is placed outdoors. In summer, under the sun, the shell temperature of the box-type substation will be too high. Moreover, the substation relies on the transformer to work. The transformer will generate a lot of heat when working. If it cannot be dissipated in time, it will have a serious impact on the work of the transformer. In addition, the high temperature can easily cause damage to the equipment inside the box-type substation and reduce its service life.

[0003] The existing box-type substation cooling device currently has uneven cooling during use, and the addition of multiple fans leads to increased costs. In addition, the cooling air temperature is high in hot weather, and the cooling effect is poor, which affects the normal use of the box-type substation components. Utility Model Content

When the monitoring signal is higher than the preset threshold, the signal is transmitted to the controller. At this time, the controller receives the signal and encodes it to control the motor to start.
