Abstract

The invention provides a pull-in type cable explosion-proof box. The pull-in type cable explosion-proof box comprises an upper explosion-proof shell and a lower explosion-proof shell; the upper explosion-proof shell and the lower explosion-proof shell are solid semi-cylinders; the outer sides of the upper and lower rectangular binding surfaces are respectively provided with upper and lower cover magnetic layers, and the upper and lower explosion-proof shells are attracted through the upper and lower cover magnetic layers to form a cylindrical shape; two ends of the upper explosion-proof shell and the lower explosion-proof shell are respectively provided with a flexible sealing assembly; and a cable penetrating pipe extrudes and penetrates through the upper and lower flexible sealing assemblies and the joint of the upper cover magnetic layer and the lower cover magnetic layer, and a first sealing cavity, a penetrating pipe containing cavity and a second sealing cavity are formed in sequence. The pull-in type cable explosion-proof box provided by the invention meets the waterproof and explosion-flashover-proof requirements of a power cable, effectively prevents water from entering the cable through a pipe, avoids the flash explosion caused by the cable being affected with damp, and guarantees the safe operation of a power distribution network.

Description

technical field [0001] The invention belongs to the technical field of electric power equipment construction, and in particular relates to a suction-type cable explosion-proof box. Background technique [0002] The cable conduit is used to protect the cable, and can distinguish the function of the cable, which is convenient for wiring and maintenance. [0003] According to the power cable laying construction requirements, the intermediate joint of the power cable must be connected to the explosion-proof box, which protects the power cable and prevents the accident caused by the flash explosion of the cable. The two ends of the cable pipes need to be sealed to prevent the insulation of the power cables from being reduced due to water ingress, thereby affecting the safety of the distribution network. [0004] In the operation and maintenance of power cables laid into the ground, due to the limitations of construction technology and plugging materials, water leakage often occu...
