Background technique

With the development of the cabling process of the distribution network, when the independent loads with small capacity are concentrated, the cable branch box can be used to connect multiple branches of the cable, because the branch box cannot directly operate each channel, and the cable branch box is widely used. For outdoor use, with the advancement of technology, the number of cable branch boxes with switches is also increasing, and urban cables often use dual-circuit power supply mode, so some people directly call the branch boxes with switches as outdoor ring network cabinets, but at present Most of such ring network cabinets cannot realize distribution automation, but manufacturers have launched outdoor ring network cabinets that can automate distribution networks, which also blurs the boundaries between cable branch boxes and ring network cabinets.

At this stage, the cable branch box generally adopts a closed structure. It is easy to generate heat inside the transmission current, which can easily accelerate the aging of the cable, or cause accidents. The electric-driven ventilation structure will also generate heat when it works for a long time. The most important thing is that the ventilation The ventilation structure only has the function of ventilation in one direction, the ventilation efficiency is low, and the air exchange effect is poor. Because the cable branch box is mostly used outdoors, in the cold weather in northern winter, the heat exchange rate between the internal heat and the external heat of the cable branch box is too fast. , the too cold environment will affect the cable, and it is easy to accelerate the aging of the cable. For this reason, we propose a cable branch box that is conducive to air exchange.
