Background

At present, the insulation treatment method of the low-voltage power wire connecting point mainly adopts the following steps: winding and wrapping the insulating tape; the prefabricated insulating material is contracted and wrapped (a hot material and a silicon rubber cold-contraction material); a plastic insulating shell is additionally arranged at the joint; all the insulation treatment modes can not meet the requirements of complete insulation and long-term water resistance, and the used insulation materials can not resist long-term ultraviolet irradiation and are easy to age and crack.

According to the national power grid standard, all low-voltage metering boxes and distribution boxes require cable incoming, and the cable branch box can conveniently tap loads, so that the low-voltage metering box is widely applied to low-voltage power distribution networks. At present, most of cable branch boxes which are applied to a low-voltage distribution network do not have breaking and protecting functions, only have functions of processing and connecting cable ends, and meet the functions of implementing tapping, branching, continuing and switching circuits on cable lines. These cable breakout boxes present the following problems during use:

1. the incoming line and the outgoing line of the cable branch box are connected through the copper busbar, and the connecting point is exposed outside, so that the potential hazard of electric shock is greatly avoided.

2. In order to ensure the operation safety, when an outgoing cable is newly added in the cable branch box each time, power failure is needed, and the complaint risk of frequent power failure exists.

3. The existing branch box is installed outdoors, and the shell is easily corroded and damaged.

4. The internal space of the cable branch box is narrow and small, and when a cable is installed to be led out, the cable head cannot be locked due to the process and the light, so that the cable branch box is heated and burnt out.

Therefore, the device for quickly and safely tapping the cable is developed, can resist the interference of the external environment, can ensure the accuracy and the stability of cable tapping, and is very important without power failure operation.
