Background
The transformer substation plays a role in the running process of the power grid. Conventional substations are fixed and require a long time to build, install and debug. In reality, the transformer substation may be damaged by various natural or human factors, thereby causing paralysis of the power grid. To cope with these possible difficulties, mobile substations have been designed to restore the function of the substation as soon as possible. The movable transformer substation is prefabricated indoor and outdoor compact type power distribution equipment in a factory, is integrated with high-voltage switch equipment, a distribution transformer and a low-voltage power distribution device into a whole according to a certain wiring scheme, is in electromechanical integration and fully-closed operation, is particularly suitable for urban network construction and transformation, and is a brand-new transformer substation rising after a civil engineering transformer substation.
Because of the inconvenient transportation, limited sites and complex terrain of many working sites of the mobile substation, there is no fixed lifting tool for loading and unloading the switch unit and the power distribution unit from the vehicle, or the deployment of the mobile lifting tool is not facilitated. Even if the lifting of the mobile substation can be smoothly realized, considerable workload is required to level the land to prepare a foundation for the installation of the mobile substation. The above work necessarily increases the construction difficulty of the mobile substation, prolongs the preparation time, and increases the cost. In addition, after the existing transformer substation works for a long time, very high heat can be generated in the box body, so that the temperature in the box body rises, a common heat dissipation mode is used for dissipating heat only through air holes or shutters on the outer wall of the box body, and in hot summer, air in the box body flows very weakly under the condition of very high external temperature, the temperature inside and outside the box body is very high, the heat dissipation effect is extremely poor, a large amount of heat generated after devices in the transformer substation work easily causes the condition that the transformer substation is powered off, and explosion can occur in severe cases. Moreover, environmental conditions around industrial and mining enterprises are mostly very severe, once a gate of an outdoor box-type transformer substation is opened, sand and dust easily enter the transformer substation, and potential safety hazards are brought to internal electrical equipment; on the other hand, the service life of the air conditioning system is reduced because the air conditioning system works continuously for 24 hours.
