Description
技术领域：Technical field:

背景技术：Background technique:
高压电缆分支箱在电力系统10kV配网电缆化工程中，以一种经济、可靠、维护方便的接线方式替代原配网架空线中大量的分支成为一大难题，而电缆分支箱的出现彻底解决了这个问题，并且以它全绝缘、全密封的特性而使线路故障率大为降低，成为配网电缆化工程的首选设备。其简单、方便、灵活的联接组合方式，使它在某些场合下，可代替环网柜；必要场合下，可埋在地下或浸于水中，节省了设备和电缆的投资，提高了供电的可靠性，广泛适用于商业中心、工业园区及城市密集区。电缆分支箱按照结构形式和电缆接头种类的不同可分为美式电缆分支箱、欧式电缆分支箱和带开关的电缆分支箱三种。In the 10kV distribution network cable project of the power system, it has become a big problem to replace a large number of branches in the overhead line of the original distribution network with an economical, reliable and easy-to-maintain wiring method, and the appearance of the cable branch box has completely solved the problem. This problem, and with its fully insulated and fully sealed characteristics, the line failure rate is greatly reduced, and it has become the first choice for distribution network cable engineering. Its simple, convenient and flexible connection combination makes it replace the ring network cabinet in some occasions; in necessary occasions, it can be buried in the ground or immersed in water, which saves the investment in equipment and cables and improves the power supply efficiency. Reliable, widely used in commercial centers, industrial parks and urban dense areas. Cable branch boxes can be divided into American cable branch boxes, European cable branch boxes and cable branch boxes with switches according to the structure and type of cable joints.
现有的开关型高压电缆分支箱的环网供电区、用户接线区以及开关本体均置于一个通体箱体内，电缆与元器件的布局没有科学合理的规划而显得杂乱，而且相互间的干扰影响较为严重，操作难度很高，操作效率低下。由于环网供电区始终处于带电状态，在工作人员进行操作时很有可能误操作，将会引发严重的生产事故，由此甚至导致严重的生命和财产损失。The ring network power supply area, user wiring area and switch body of the existing switch-type high-voltage cable branch box are all placed in a whole box. More serious, the operation difficulty is very high, and the operation efficiency is low. Since the power supply area of the ring network is always in a charged state, it is very likely that the staff will misuse it when operating, which will cause serious production accidents, and even cause serious loss of life and property.
