Problems solved by technology

[0003] For the sake of safety and economy, the power lines of the low-voltage distribution network are all insulated wires wrapped with insulating skins. Insulated wires are connected or released multiple times. For example, when the three-phase load of the low-voltage distribution network is unbalanced, in order not to affect the normal power consumption of users, the grid staff needs to perform phase adjustment on the original three-phase load. It is necessary to disconnect the main switch of the distribution station area before, and the user needs to cut off the power. When adjusting the phase, it is necessary to peel off the barge interface at the "T" connection of the overloaded phase line of the original low-voltage power line, and then select the phase line with a lower load to reconnect it. It takes a long time for the staff and indirectly leads to long power outages for users; when the power is out for maintenance, it is necessary to peel off the insulation sheath of the insulated wires and then install the grounding wire. After the maintenance is completed, remove the grounding wire and wrap it back with insulating tape Insulation openings; in order to improve the power quality of users when the distribution station area is out of power, it is necessary to connect a temporary generator car to the low-voltage distribution network, and the temporary generator car also needs to peel off the insulation wire of the insulated wire or untie the station area. If the lugs of the low-voltage switch outlets are connected, the above situations will cause certain damage to the insulation of the low-voltage wires, and repeated connection and release of the wires will lead to poor line stability, easy power failure, and potential safety hazards; There are many steps in the operation, which consumes a lot of time for the staff, and also causes the consequences of low work efficiency of the staff and long power outages for users. Therefore, a distribution network connection branch line device and method for power distribution network engineering construction are proposed.

Description

technical field [0001] The invention relates to the technical field of electric power distribution network engineering, in particular to a distribution network connection branch line device and a method thereof for the construction of electric power distribution network engineering. Background technique [0002] The distribution network refers to the power network that receives electric energy from the transmission network or regional power plants, and distributes it locally through power distribution facilities or distributes it to various users step by step according to voltage. It is composed of overhead lines, cables, towers, distribution transformers, isolating switches, reactive power compensators and some auxiliary facilities, etc., and plays an important role in distributing electric energy in the power network. [0003] For the sake of safety and economy, the power lines of the low-voltage distribution network are all insulated wires wrapped with insulating skins. ...
