Description
Technical Field
The utility model relates to the technical field of mechanical device, concretely relates to be applied to box-type substation's exhaust fan strutting arrangement.
Background
Due to the convenience of outdoor use, the box-type substation is very popular in application as an intermediate link of power supply and distribution. A transformer room, a high-voltage room and a low-voltage room are generally separated in the box-type substation, and the area of each room is not large. After the formal power transmission is put into use, a large amount of heat can be generated in the whole box body due to the load operation of the transformer and each power distribution cabinet, and in order to ensure ventilation and heat dissipation, an exhaust fan is designed on the box body when a general box-type substation leaves a factory. In order to improve the service cycle of the exhaust fan and avoid long-time invalid operation, the power supply of the exhaust fan is generally led from the load side of the temperature controller of the transformer, when the indoor temperature of the transformer is too high, the output power supply of the temperature controller is started and provided with a cooling fan, and meanwhile, the exhaust fan on the box body is started to take out heat. Although the continuous operation of the exhaust fan is avoided and the service life of the exhaust fan is prolonged, the exhaust fan is difficult to avoid damage after a long time. At present, the exhaust fan is generally installed at the inner side of the box body, and when the exhaust fan needs to be replaced, the exhaust fan needs to be replaced inside the box body. During operation, operating personnel is very close to electrified body distance, in order to guarantee safety, can only have a power failure in time or overhaul and change when having a power failure. An instant power failure, whether for residential, commercial or industrial use, can be associated with unnecessary trouble and loss. When the maintenance is carried out, power is cut off, and in the time before the maintenance, the interior of the box body is continuously high in temperature, so that tripping or fire accidents can be caused, and therefore, an operator needs to erect an additional temporary exhaust fan for heat dissipation and air exhaust. Currently, this problem has not been solved in a manner that is both safe and easy.
