Problems solved by technology

During the use of the cable, the distance between the cable and the heat pipe is too close or the cable is overloaded for a long time, and the temperature is too high to age the insulating material, resulting in a decrease in insulation performance, breakdown and ignition; the protective layer of the cable is damaged when the cable is laid or the cable is damaged. The insulation is mechanically damaged during operation, causing insulation breakdown between the phases and outer layers of the cable; the intermediate joints of the cable are not crimped tightly, the welding is not firm, and oxidation occurs during operation; the dosage of insulating material injected into the intermediate joint box of the cable does not meet the requirements, or There are air holes in the box when pouring; the cable box is not well sealed or the damaged crack is immersed in moisture, which will cause insulation breakdown, fire and explosion, so the hidden danger of cable joint problems is inevitable
[0003] At present, there are many kinds of waterproof and explosion-proof joint boxes on the market, most of which are in the form of upper and lower half-shell bolt connections, and the cable ends and grounding outlets cannot be effectively waterproof; the middle joint of the cable itself has a relatively high operating temperature. The temperature will be higher, which will greatly increase the failure rate and affect the safe operation of the joint. At present, the waterproof and explosion-proof joint box on the market basically cannot prevent the occurrence of fire, and cannot effectively extinguish the fire in time after a fire occurs;

Abstract

The invention discloses a waterproof and explosion-proof fire extinguishing box of a cable connector. The waterproof and explosion-proof fire extinguishing box comprises a cavity and a cover body, wherein the cover body and the cavity are connected to form a closed explosion-proof cavity of the cable connector, two energy discharging guide pipes and two groups of fire extinguishing assemblies arearranged on the cover body, each fire extinguishing assembly comprises a fire extinguishing pipe and a smoke sensor, a solenoid valve is arranged at a lower end of the fire extinguishing pipe, the solenoid valve is electrically connected with the smoke sensor, a fire extinguishing agent injection hole is formed in an upper end of the fire extinguishing pipe, and a fire extinguishing pipe is filledwith a fire extinguishing agent. The waterproof and explosion-proof fire extinguishing box of the cable connector is compatible with functions of fire extinguishing and energy discharging, the fire extinguishing assembly is used for extinguishing fire when the cable connector is failure and is ignited, the harm is prevented from being further expanded, and the safety of a cable well is ensured; with the adoption of a mode that the cavity and the cover body are combined and connected, the cable connector is convenient to install and has favorable sealing performance; and the energy dischargingguide pipes and the fire extinguishing assemblies are all integrated on the cover body, the production efficiency is favorably improved, and the waterproof and explosion-proof fire extinguishing boxis also more convenient to install, use and store.

Description

technical field [0001] The invention belongs to the technical field of waterproof and explosion-proof boxes for cable joints, in particular to a waterproof and explosion-proof fire extinguishing box for cable joints. Background technique [0002] The cable intermediate joint is the weakest link of the cable. Cable intermediate joints are inevitably used in the long-distance cable laying process. In the process of urban construction, for the sake of beautification and safety, more and more high-voltage overhead lines are laid underground, and cable trenches and cable ducts are laid. Therefore, there will be more and more cables and cable intermediate joints in cable trenches and cable tunnels in the future. During the use of the cable, the distance between the cable and the heat pipe is too close or the cable is overloaded for a long time, and the temperature is too high to age the insulating material, resulting in a decrease in insulation performance, breakdown and ignition...
