1 is a perspective view illustrating a busbar structure of a gas insulated switchgear according to an embodiment of the disclosed technology, FIG. 2 is a front view illustrating a busbar structure of the gas insulated switchgear of FIG. 1, and FIG. 3 is a gas of FIG. 1. It is a right side view explaining the busbar structure of the insulated switchgear.

1 to 3, the busbar 100 of the gas insulated switchgear includes an enclosure 110, first and second coupling parts 120 and 130, ribs 140, and a cooling unit 150. The first connection part 160 and the second connection part 170 are included.

The enclosure 110 forms an exterior of the bus bar 100 and is filled with an insulating gas inside. In one embodiment, the enclosure 110 may be formed of a material of stainless steel. In another embodiment, when the enclosure 110 is made of steel, at least one of the upper, lower and both sides of the enclosure 110 may be formed of a stainless material. When the entire enclosure 110 is made of steel, when a large current flows, eddy currents are generated along the inner wall of the enclosure 110 to generate high heat in the enclosure 110. However, when at least one of the upper, lower and both sides of the enclosure 110 is formed of a stainless material, it is possible to prevent the formation of a closed loop to block the eddy current to prevent heat generation due to the eddy current.

The first and second coupling parts 120 and 130 protrude from the front part of the enclosure 110 and are spaced apart from each other. Each of the first and second coupling parts 120 and 130 may be connected to a disconnector and a ground switch of the gas insulated switchgear.

Ribs 140 are formed in plural on both sides of the enclosure 110. Lip 140 increases the outer area of enclosure 110. This may increase the heat dissipation area generated inside the enclosure 110, and consequently increase the heat dissipation efficiency of the enclosure 110. In one embodiment, the lip 140 may be formed of a material of carbon steel. This is to increase the heat dissipation performance.

The cooling unit 150 is provided at the upper end of the enclosure 110, and controls the temperature of the bus bar 100 to rise due to heat generated therein. In one embodiment, the cooling unit 150 may be formed of a material of carbon steel or aluminum to increase heat dissipation performance.

The first connector 160 includes a plurality of connection receivers and is formed on one side of the enclosure 110.

The second connector 170 includes a plurality of connection protrusions and is formed at the lower end of the enclosure 110.

The function of the disclosed technology is described as follows. The busbar enclosure 110 of a general gas insulated switchgear is made of stainless steel or iron plate. When the enclosure 110 is made of stainless steel, it is possible to suppress the eddy currents inside, but there is a problem in that the manufacturing cost is high, and when manufactured in steel, there is a problem that cannot suppress the eddy currents generated inside. In addition, the large-capacity gas insulated switchgear flowing a large current has a problem that it is difficult to effectively discharge the high heat due to the large current. The busbar tank 100 of the gas insulated switchgear according to the disclosed technology includes a plurality of ribs 140 on both sides of the enclosure 110 to increase the area of the enclosure 110 so that the heat dissipation area is increased to emit high heat. It can be formed in an easy structure. In addition, when the enclosure 110 is made of steel, at least one of the upper, lower and both sides of the enclosure 110 may be formed of a stainless material. When the entire enclosure 110 is made of steel, when a large current flows, eddy currents are generated along the inner wall of the enclosure 110 to generate high heat in the enclosure 110, but When at least one of the upper, lower and both sides is formed of a stainless material, it is possible to prevent the formation of a closed loop to block the eddy current to prevent heat generation due to the eddy current.
