Description

Technical Field

[0001] The invention relates to the technical field of gas boxes, in particular to a gas box assembly based on a direct current GIS. Background Art

[0002] The gas box assembly based on DC GIS (full name GAS insulated SWITCHGEAR, Chinese: gas insulated switchgear) is a vital component of the power system. Its assembly quality and performance directly affect the operating reliability and safety of the entire GIS equipment. The gas box body of the gas box assembly based on DC GIS is the main structure of the GIS equipment. It is usually made of corrosion-resistant materials such as stainless steel and is filled with insulating gas (such as SF 6 ) to ensure the electrical insulation performance of GIS equipment. The gas box assembly based on DC GIS currently used is sealed during the design, manufacturing and installation process. This sealing is to ensure that the SF filled in the gas box is 6 (sulfur hexafluoride) insulating gas will not leak, thus maintaining the safe and reliable operation of GIS equipment. However, the temperature inside the gas box will rise, and effective heat dissipation will not be achieved. High temperature will cause the performance of the insulating material inside the gas box assembly to deteriorate, and the insulation strength will decrease, thereby increasing the risk of insulation failure in the equipment. Long-term high temperature environment will accelerate the aging process of the insulating material and shorten the service life of the equipment. When the temperature inside the gas box cannot be effectively dissipated, the high temperature environment will aggravate the heat accumulation inside the equipment, affecting the heat dissipation effect of the equipment, causing the temperature of the equipment to rise, further aggravating the above hazards, and high temperature may cause SF 6 Gas hydrolysis and toxic gas generation increase the risk of operators being exposed to harmful gases.

In this embodiment, a cooling fan is arranged at the end of the air box, so that when it is inconvenient to install a heat pipe 7 on the air box to transport cooling liquid or liquid medium for cooling, another method can be selected for temperature control and cooling. According to the different equipment and wiring installed on the upper end of the air box, the bottom end of the track frame 19 can be slid and adjusted in the fixed limiting structure 23 by screwing the locking structure 22, so that the use position of the lifting adjustment plate 18 and the cooling fan 24 can be indirectly controlled and adjusted, so that the lifting adjustment plate 18 and the cooling fan 24 will not affect the equipment and wiring installed on the upper end of the air box, and then each cooling fan 24 is started, so that the cooling fan 24 can fully cool and dissipate the top of the air box and the guide heat sink 5 and the guide ring 6 arranged on the top of the air box, and starting the lifting drive structure 20 can make the lifting adjustment plate 18 rise and fall on the track frame 19, so that each cooling fan 24 rises and falls, and adjusts and controls the heat dissipation area of ​​the cooling fan 24, so that the heat dissipation and cooling are more sufficient.
