The invention discloses a three-
phrase integration
solid insulating looped
network switch device. The three-
phrase integration
solid insulating looped
network switch device comprises a
bus line cone, an arc extinguish chamber, a
solid closure pole, an isolation cutter, a switching on contact, a base, a main shaft and a
phase line cone. A
silicon rubber sealing sleeve is arranged between the
bus line cone and the solid closure pole, the isolation cutter is fixed in the solid closure pole through the main shaft, the top of the isolation cutter is in electric connection with the arc extinguish chamber through the switching on contact, the isolation cutter is connected with an outlet part of the base, on end of the
phase line cone is connected with the bottom of the base, the other end of the
phase line cone is an outlet end, and a
silicon rubber sealing layer is arranged between the phase line cone and the base. The three-
phrase integration solid insulating looped
network switch device is simple and compact in structure, an electric appliance connecting part adopts watch chain touch finger connection, the isolation
cuter, the arc extinguish chamber and the switching on contact are sealed in the solid closure pole, sealing performance is good, no harmful substances can be generated during working process, environmental
pollution is little, effect on
electrical performance of a ring main unit from external environment is little, using stability of the device is improved for a certain extent, and service life of the device is prolonged.
