Abstract

The invention discloses a protective box of a cable intermediate joint, comprising a first housing and a second housing which are in fastening connection with each other, wherein a first power release hole and a second power release hole are respectively formed in two ends of the first housing and portholes of the first and second power release holes are sealed with a silicon rubber sealing plug; grooves matching with cables are formed in two ends inside the housings of the protective box; cables at two ends respectively penetrate inside the housings of the protective box and are electrically connected by the cable intermediate joint therein; the inside of the protective box is filled with a protective material. The protective box is integrated with the functions of power release, flame resistance, waterproofing and explosion proof, effectively solves chain reaction caused by cable faults and prevents the cables from chain-reaction accidents, and operating environment of the cable intermediate joint is ensured so as to reduce operating faults, and thus the protective box has advantages of convenience for installation and change and simple construction.

Description

technical field

[0001] The invention relates to a cable intermediate joint box, in particular to a cable intermediate joint protective box with fireproof, waterproof and explosion-proof functions. Background technique

[0002] Electricity is the main source of power for production and life in today's society. With the continuous expansion of today's cities and the increasing level of modern production, the transmission and power supply system presents the characteristics of: a huge power supply network, a complex power supply system, many power supply links, and long power supply distances. As an important connection point of the entire power supply network, the cable intermediate joint, its operation stability will directly affect the operation quality of the power supply system.

[0003] Since the cable intermediate joint is installed manually on site, affected by the construction environment and operating environment, breakdown and explosion accidents will inevitably occu...
