Portable wiring device of low-voltage power distribution network

Abstract

The invention discloses a portable wiring device for a low-voltage power distribution network. The portable wiring device comprises an insulating base, a cover body and a metal connector, wherein thecover body and the insulating base are connected to form a combined body, the metal connector is arranged in the combined body, and the power supply side wire penetrates into the insulating base and is electrically connected with the load side wire through the metal connector. According to the device, the defect of low working efficiency of workers due to various operation steps of the traditionalwiring mode is overcome, and the damage to the insulation of the low-voltage wire caused by the traditional wiring mode is reduced, so that the power failure time of a user is further shortened.

Description

technical field [0001] The present invention relates to the technical field of power system wiring devices, and more specifically, to a portable wiring device for a low-voltage distribution network. Background technique [0002] 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 conductors are spliced ​​or unbonded multiple times. [0003] 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 modulation on the original three-phase load. Switching, the user needs to cut off the power, and 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, which takes a long ti...

Problems solved by technology

[0003] 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 modulation on the original three-phase load. Switching, the user needs to cut off the power, and 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, which takes a long time for the staff and indirectly causes the user The power outage lasts for a long time; when the power outage is overhauled, it is necessary to peel off the insulation sheath of the insulated wire and then install the grounding wire. In order to improve the quality of electricity consumption of users, it is necessary to connect temporary generator vehicles to the low-voltage distribution network, and the temporary generator vehicles should also be connected by stripping off the insulated wire sheath of the insulated wires or untying the lugs of the low-voltage switch outlets in the station area.

[0004] The above situations will cause certain damage to the insulation of the low-voltage wires, and repeated connection and removal of the wires will lead to poor line stability, easy power failure, and potential safety hazards; in addition, due to the many operation steps of the connection, it takes a lot of time for the staff , also caused the consequences of low work efficiency of staff and long power outages of users
