Abstract
The utility model discloses an epoxy sleeve upper electrode for a GIS (Gas-Insulated Switchgear) gas-insulated metal-enclosed switch. The epoxy sleeve upper electrode comprises an epoxy sleeve and an upper electrode, wherein the outer edge of the upper electrode is inlaid on the inner diameter of the epoxy sleeve and provided with a raised edge. According to the utility model, the longitudinal edges are additionally arranged on the edges of the upper electrode and the sleeve, the whole enclasping force of with the epoxy sleeve is enlarged, the thermal stability of the sleeve when a combined switch has short circuit is enhanced, and the safe and reliable working requirements can be realized.
Description
Technical field
The utility model relates to the electric cable accessories technical field, specifically is that a kind of GIS (Gas Insulated Switchgear, Cubicle Gas-Insulated Switchgear) gas-insulated metal enclosed switchgear is used the epoxy bushing upper electrode.
Background technology
According to the IEC60859 standard-required, the 110kv power cable need support and contact with prolonging to manage with upper electrode with being connected of SF6 gas-insulated metal enclosed switchgear with epoxy bushing.Existing epoxy bushing upper electrode material is with T2 type copper material processing and fabricating, and owing to copper and epoxy resin shrinkage differ greatly, copper and epoxy resin faying face are easy to generate the gap, and are difficult for being examined discovery, causes that product quality has major hidden danger in the high-voltage operation.
The utility model content
The utility model technical problem to be solved provides a kind of safe and reliable GIS gas-insulated metal enclosed switchgear and uses the epoxy bushing upper electrode.
The described a kind of GIS gas-insulated metal enclosed switchgear of the utility model is used the epoxy bushing upper electrode, comprises epoxy bushing and upper electrode, and said upper electrode outer rim edge is enclosed within on the epoxy bushing internal diameter, and said upper electrode outer rim is provided with the rib of protrusion.
The utility model is through upper electrode and sleeve edge increase rib longitudinally, strengthens the power of holding tightly with epoxy bushing integral body, and the thermal stability of sleeve pipe has realized safe and reliable job requirement when having strengthened the unit switch short circuit.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1; A kind of GIS gas-insulated metal enclosed switchgear of the utility model is used the epoxy bushing upper electrode; Comprise epoxy bushing 1 and upper electrode 2, said upper electrode 2 outer rims edge is enclosed within on epoxy bushing 1 internal diameter, and said upper electrode 2 outer rims are provided with the rib 3 of protrusion.
The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement, these improve the protection range that also should be regarded as the utility model.
