Embodiment 1

[0029] A plugging device based on the application of substation cables in the present invention includes a cable cover 3, and two clamping blocks are arranged inside the cable cover 3, and the two clamping blocks are respectively located on both sides of the inner wall of the cable cover 3. The holding block includes two symmetrically arranged blocking blocks 2, which can move along the radial and axial directions of the cable sheath 3, and the blocking block 2 is provided with an inclined surface 12 between the two blocking blocks 2. The inclined surface 12 forms a placement cavity 13, and the placement cavity 13 is filled with fireproof cement 9, and the blocking block 2 can be fixed to the fireproof cement 9 on the cable. The blocking block 2 is also provided with an elastic piece 6, one end of the elastic piece 6 is connected with the blocking block 2, and the other end is connected with the inner wall of the cable sheath 3, when the elastic piece 6 is not subjected to exte...

Embodiment 2

[0031] On the basis of embodiment 2, a plurality of plugging rods 5 are also arranged on the cable cover 3, and the plugging rods 5 are evenly distributed on the outside of the plugging block 2, and the plugging rods 5 connect with the cable sleeve 3 through threads. Connect, rotate the blocking rod 5, and the blocking rod 5 can move along the radial direction of the cable sleeve 3.

Abstract

The invention discloses a blocking device applied to a substation cable. The device comprises a cable sleeve, the cable sleeve is internally provided with two clamping blocks, the two clamping blocksare located on two sides of an inner wall of the cable sleeve, the clamping blocks comprise two symmetrically arranged blocking blocks which can move in the radial and axial directions of the cable sleeve, the blocking blocks are provided with inclined surfaces, the inclined surfaces of the two blocking blocks form a placement cavity which is filled with fireproof glue, and the blocking blocks canfix the fireproof glue to the cable. According to the device of the invention, the fireproof glue set on the cable can be limited by the blocking blocks and is prevented from falling from the cable,and the holding strength of the fireproof glue to the cable is improved.

Description

technical field [0001] The invention relates to the technical field of substation safety, in particular to a plugging device based on the application of substation cables. Background technique [0002] The substation is the hub of the entire power transmission and transformation system, and it plays an important role in linking the past and the future. The cable blocking of control cabinets, switch cabinets, cable layers, cable penetrations, cable firewalls, etc. in substations is directly related to whether electrical equipment can operate safely The openings of cabinets, boxes, and the openings where cables pass through protective tubes should be sealed with fire protection. Currently, the measures for sealing cable holes in substations under the jurisdiction are due to the insufficient pressure of the plugging materials on the attachments or the fireproof cement and The poor fit of the cables often causes the plugging material to fall off, and the repaired part may colla...
