Embodiment
Below in conjunction with the accompanying drawings to a kind of the specific of high-voltage cable middle joint waterproof anti-explosion flame failure protection shell of the utility model
Embodiment is described in detail, and the embodiment is merely to illustrate the utility model rather than limitation model of the present utility model
Enclose, modification of the those skilled in the art to the various equivalent form of values of the present utility model falls within the application appended claims and limited
Fixed scope.
Such as Fig. 1, a kind of high-voltage cable middle joint waterproof anti-explosion flame failure protection shell, in cable passage under protecting field
The safety of high-voltage cable joint, including left shell 2 and right shell body 7, the left shell 2 and right shell body 7 pass through rubber blanket 12 and spiral shell
Bolt is fixedly connected, and rubber blanket 12 uses corrosion resistant high elastic rubber, overall pressure-resistant more than 1.0MPa, it is medium to tackle long period of soaking water
Adverse circumstances, left shell 2 are connected with the wire outlet part of high-tension cable 3, left shell 2 and right shell body 7 with the another side that right shell body 7 is connected
Cross sectional shape be square, circular or polygon, such as Fig. 4, the cross sectional shape of right shell body 7 is circle；Such as Fig. 3, high-tension cable 3 goes out
Line position outer layer is held tightly by sealing shroud 10 and wedging ring 9 successively, and sealing shroud 10 uses high resiliency corrosion resistant quality of rubber materials, reaches effective
Waterproof；Such as Fig. 2, enclosure interior is equipped with more radiating tubes 4, and radiating tube 4 not only increases 100% area of dissipation, and left
It is right to form cross-ventilation, the running temperature of cable connector is effectively reduced, greatly reduces failure risk, radiating tube 4 can also rise
