Flame-retardant wire fixing device and electrical cabinet

Abstract

The invention provides a flame-retardant wire fixing device and an electrical cabinet. The flame-retardant wire fixing device comprises a wire fixing shell and an air bag, wherein the wire fixing shell is provided with a mounting surface suitable for being fixed on a wiring component, and is also provided with a threading hole suitable for a cable to pass through; the air bag is arranged on the hole wall of the threading hole and used for wrapping and clamping the cable or used for being matched with the hole wall of the threading hole to clamp the cable. The air bag is filled with flame-retardant gas, and the air bag is broken at high temperature to release the flame-retardant gas when the cable is overheated or burnt due to a line fault. According to the flame-retardant wire fixing device provided by the invention, flexible installation and wiring can be carried out according to a wiring path, the wiring cost is saved, the air bag can reliably fix cables with different diameters, the applicability is high, when the cables are overheated or burnt due to line faults, the air bag is broken at high temperature to release flame-retardant gas, and the flame-retardant effect is good. The cable can be quickly isolated from air so as to prevent high-temperature combustion of the cable or prevent further combustion of the cable.

Description

technical field [0001] The invention belongs to the technical field of wire fixing accessories for electrical cabinets, and in particular relates to a flame-retardant wire fixing device and an electrical cabinet. Background technique [0002] When wiring the electrical cabinet, it is necessary to fix the wire groove on the wiring path. Since the wire groove is a fixed length, it is necessary to cut the wire groove according to the specific size of the wiring path in the actual operation process. For the length after cutting Shorter wire ducts will be treated as waste, which will result in a lot of material waste, and because the size of the slot hole of the wire slot needs to be larger than the diameter of the cable passing through, the cable will shake inside the wire slot, especially for thinner wires As far as the cables are concerned, they often need to be fixed with cable cards in the wire grooves, which not only affects the wiring efficiency, but also increases the wir...
