A tractor-type mobile substation

Abstract

A tractor-type mobile substation The tractor-type mobile substation comprises a box body and a bottom plate, wherein the box body is arranged on the bottom plate; the box body comprises a roof plate and an external wall plate; the bottom plate of the external wall plate is fixedly connected with the bottom plate; the bottom plate comprises two sliding beams; the cross section of the sliding beam is designed as a ship shape; and buffer plates are respectively arranged at two ends, so as to facilitate the movement and suspension of the substation. The cable bridge beneath the auxiliary beam is used for laying cables at the bottom of the substation. The air conditioner can keep the temperature in the substation in a constant range, which improves the safety of the electric equipment in the substation. The sand baffle can prevent the sand from entering the air conditioner, and prolongs the service life of the air conditioner. The booster device makes the indoor air pressure of the substation higher than the external atmospheric pressure, which can effectively prevent the wind sand from entering the inside of the box when people enter or leave the box-type substation in a short period of time.

Description

technical field [0001] The invention relates to the technical field of power distribution equipment, in particular to a drag type mobile substation. Background technique [0002] Substations play a pivotal role in the operation of the power grid. Conventional substations are fixed, and their construction, installation and commissioning take a long time to complete. In reality, substations may be damaged due to various natural or human factors, resulting in grid failure. In order to deal with these possible difficulties and restore the function of the substation as soon as possible, people have designed the mobile substation. Mobile substation is a kind of factory prefabricated indoor and outdoor compact power distribution equipment that integrates high-voltage switchgear, distribution transformer and low-voltage power distribution device according to a certain wiring scheme. It is mechanical and electrical integration, fully enclosed operation, especially suitable for Urb...

Problems solved by technology

The above work will inevitably increase the construction difficulty of the mobile substation, prolong the preparation time, and increase the cost

In addition, after the current substation works for a long time, the box will generate a lot of heat, which will cause the temperature inside the box to rise. The general heat dissipation method is to dissipate heat through the air holes or louvers on the outer wall of the box. For the hot summer, When the external temperature is very high, the air flow in the box is very weak, and the temperature inside and outside the box is very high, the heat dissipation effect is extremely bad, and the large amount of heat generated by the components in the substation can easily make the substation In the event of a power outage, an explosion may occur in severe cases

Moreover, the surrounding environmental conditions of industrial and mining enterprises are mostly very harsh. Once the door of the outdoor box-type substation is opened, sand and dust can easily enter the substation, bringing safety hazards to the internal electrical equipment; on the other hand, because the air conditioning system works 24 hours a day, Reduced service life of the air conditioning system
