Description
Technical Field

Background
GIS (gas insulated metal enclosed switchgear) is widely used in the high voltage field with the advantages of small occupied area, long maintenance period, high safety and reliability, etc. In GIS engineering, the basin-type insulator is an important insulating component, and functions as: 1. the bus and the plug-in contact of the bus are fixed, so that the bus can pass through the basin-type insulator and can go from one air chamber to the other air chamber; 2. the bus is insulated from the ground or the interphase; 3. and plays a role in sealing. At present, the basin-type insulator is formed by pouring epoxy resin and other additives under high vacuum, no bubbles or cracks exist in the basin-type insulator, and a finished product is identified by a partial discharge test.
In GIS, upper and lower adjacent two equipment casings pass through basin formula insulator mounting structure and connect, and basin formula insulator mounting structure includes first equipment flange, second equipment flange and basin formula insulator, and basin formula insulator is compressed tightly and is fixed between first, second equipment flange, and the hookup location of two equipment flanges and basin formula insulator do not is equipped with the bolt hole that the axis extends along upper and lower direction respectively, and the bolt passes the bolt hole on two equipment flanges and the basin formula insulator in proper order and cooperates the nut to fasten. In order to prevent outdoor GIS from water inflow, generally, waterproof glue is smeared on a bolt to ensure tightness, but because an outdoor station needs to be subjected to long-time wind and sun exposure, the waterproof glue is easy to fail. After the waterproof adhesive on the bolt fails, rainwater can possibly flow into the bolt holes on the basin-type insulator and the equipment flange through gaps between the bolt and the corresponding bolt hole, if the rainwater in the bolt holes on the basin-type insulator mounting structure cannot be completely discharged, when low-temperature weather is met, the rainwater remained in the bolt holes on the basin-type insulator can freeze and expand and extrude the basin-type insulator, after long-time repeated extrusion, the basin-type insulator is easy to crack to cause air leakage, and hidden danger is brought to the safe operation of GIS equipment.
