Abstract

The invention discloses an assisting device for connecting a cable into a ring main unit without power outage. A wiring seat (1) is installed in a ring main unit body; a T-shaped front connector (5) of which the sheath is made of an all-insulation material is mounted on the wiring seat (1); a wiring double-screw bolt (6) is mounted in the T-shaped front connector (5); and the No. 1 wiring terminal of an operating cable is connected with the wiring seat (1) through the wiring double-screw bolt (6) and is pressed by a No. 1 wring nut (8). The assisting device is characterized in that the assisting device enabling the cable to be connected into the ring main unit without power outage is configured for the ring main unit; the assisting device includes an insulation-assisting protective baffle and a connection-assisting bridging mechanism. The assisting device has the advantages of simple structure and convenient operation. With the assisting device adopted, a device for connecting a bypass cable into a ring main unit having no standby intervals without power outage can be provided.

Description

technical field [0001] The invention relates to tooling for bypass operation without power failure, in particular to an auxiliary device for connecting cables to a ring network cabinet without power failure. Background technique [0002] With the continuous development of urban distribution networks, non-stop operation has become a trend. At present, more and more bypass non-stop operations of power systems have been extended from overhead lines and related equipment to cable lines. The non-stop maintenance and replacement of network cabinets have been normalized. [0003] At present, there are generally two operation methods for the non-stop maintenance of the ring network cabinet. One is to adjust the load of the line to vacate the load of the ring network cabinet to be repaired or replaced through the switching operation, so that the load carried by it is transferred to other Ring network cabinet, this kind of operation method is suitable for ring network lines or dual p...
