A cable clamping device and a power distribution cabinet thereof

Abstract

The invention discloses a cable clamping device and a power distribution cabinet thereof. The device comprises a cable fixing clamp, cable grooves are formed in the cable fixing clamp, a cable is arranged in the cable groove, a heat conduction plate is fixedly arranged in an inner cavity, close to the cable grooves, of the cable fixing clamp; the cable is arranged in a left cable groove and a right cable groove in a penetrating mode, and an open fire detection sensor is arranged on a connecting rod; heat dissipation blades are fixedly arranged on a rotating rod; a push plate is movably arranged in a pipe cavity of a fire extinguishing agent pipe, the fire extinguishing agent pipe is communicated with a communicating pipe, and a plurality of spraying openings are formed in the side, close to the cable fixing clamp, of an outlet pipe. According to the cable clamping device, a warning device for preventing the cable from being pulled rigidly is arranged in the cable clamping device, the cable can be also cooled; a fire extinguishing agent spraying device is automatically triggered when open fire occurs, so fire spreading is prevented; the invention further discloses the power distribution cabinet comprising the cable clamping device, and the device is good in using effect and quite worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of power distribution cabinets, in particular to a cable clamping device and a power distribution cabinet. Background technique [0002] In the prior art, a cable clamping device for a power distribution cabinet with the application number "201610775981.6" includes a horizontal plate and an arc-shaped plate. One end of the arc-shaped plate and the horizontal plate is equipped with a threading assembly, and the threading assembly includes The frame body is provided with a first clamping plate and a second clamping plate; an elastic component is arranged between the first and second clamping plates, since the clamping device includes a horizontal plate, an arc plate, and a horizontal plate and arc-shaped plates are provided with threading components, the threading components include a frame, a first clamping plate and a second clamping plate are arranged in the frame, and an elastic component is provided betwe...

AI Technical Summary

Problems solved by technology

[0003] However, there are still relatively obvious defects in its use: 1. The above-mentioned cable clamping device lacks the necessary heat dissipation structure, so that the clamped part of the cable is easily caused by heat accumulation due to the lack of air circulation, which will not only damage the cable, but also cause damage to the cable. There is also a potential safety hazard of fire; 2. The above-mentioned device lacks an emergency fire extinguishing device. When the cable and its clamping device catch fire, the fire cannot be extinguished in time, and the alarm cannot be triggered to remind people to take emergency measures, which is likely to cause the fire to spread; 3. When the operator is installing, using or overhauling the cable, there may be a phenomenon of pulling the cable by mistake. The above-mentioned device lacks a reminder device for pulling the cable hard, so that the operator may use too much force, causing the cable to break
