Box-type switching station

Abstract

The invention discloses a box-type switching station which comprises an outer box body, a bottom groove is formed in the bottom of the outer box body, air guide cavities are formed in the two sides of the interior of the outer box body, guide rail columns are arranged at the two ends of the two sides of the interior of the outer box body, and guide blocks matched with one another are arranged on the inner sides of the four guide rail columns, inner box bodies connected with each other are arranged on the sides, close to each other, of the two guide blocks on the same side. Through mutual cooperation of heat dissipation and air exhaust assemblies, heat dissipation air can be formed in the inner box bodies through rotation of first fan blades and two sets of second fan blades which are obliquely arranged, and the second fan blades are forced to rotate in a surrounding mode under meshing of a rotating rod and a bevel gear ring through rotary sliding of a sliding block and an annular sliding groove, and meanwhile, the heat dissipation air exhausted from the inner box bodies can form flow guide in the air guide cavities under the cooperation of two sets of servo motors and spiral flow guide rods, the heat dissipation air can be rapidly exhausted from the outer box body, and the heat dissipation efficiency of the device is improved.

Description

technical field [0001] The invention relates to the technical field of power distribution equipment, in particular to a box-type switchgear. Background technique [0002] The switch station refers to the power supply and distribution facilities used to receive and distribute power. The high-voltage power grid is called a switch station. The switch station in the medium-voltage power grid is generally used for receiving and distributing 10kV power. There is a medium-voltage power distribution facility. The power distribution device for incoming and outgoing lines and redistribution of power is equivalent to the extension of the substation busbar. It can be used to solve the limited interval between the incoming and outgoing lines of the substation or the restricted corridor of the incoming and outgoing lines, and play the role of power supply in the area.

Problems solved by technology

[0003] The current box-type switchgear is generally installed and installed outside. However, the outside climate is changeable. In hot weather, the heat source generated by the current flow in the device will be larger, which will cause the heat dissipation system to be unable to fully discharge the heat source in the equipment and increase the number of components. In the rainy season, external moisture can easily enter the device, making the components damp, affecting the normal use of the equipment, reducing the safety measures for the actual use of the equipment, reducing the functionality of the device and the practical value of the external assembly; in the equipment It is often necessary to open the switchgear during assembly or follow-up maintenance of the components. However, the space of the box-type switchgear is limited and it is not easy to fully expand, which limits the operating space of the staff and increases the work of maintenance and parts installation. The implementation is difficult and inconvenient. When the heat dissipation system in the equipment is in operation, the gas conductivity is poor, and the heat source is easy to concentrate in the equipment in large quantities, which cannot be quickly drained, thereby increasing the heating surface and damage of the components in the equipment and reducing the components. service life
