A kind of tri-station isolating switch; by three independently isolating switch connect and compose side by side; it is characterized in that: described each isolating switch main body is a casing; in the casing is working space; one layer insulating is set on the outer wall of casing; it is the shield semiconductors layer that the macromolecule modified material of main body is made based on ethylene-propylene diene copolymer that the outside of insulating barrier also is provided with one deck; be used to play outer wall mask switch inner high voltage electric field to tri-station isolating switch; play ground protection; reach tangibly effect; on the described casing; a side is provided with operating state connection contact on two corresponding sidewalls; ground state is set on the opposite side connects contact; be provided with conductive contact blade between described operating state connection contact and the described ground state connection contact, connect conversion joint between the contact, switch operating state at two by conductive contact blade; described conductive contact blade connects an outlet conductive contact, passes behind the sidewall of casing and cable joins.
Described conductive contact blade is arranged in the interior working space of casing, at conductive contact blade and outlet conductive contact junction rotating shaft is set, and by rotating shaft conductive contact blade and outlet conductive contact is flexibly connected.
The two ends of passing conductive contact blade in described rotating shaft also are provided with spring leaf, are used to compress conductive contact blade, do not influence the rotation of conductive contact blade simultaneously.
The utility model can charge into gas in use in described working space, form the space of insulation in working space, avoids conductive contact blade to connect in working order when switching between contact and the ground state connection contact and produces electric arc between the metal.
Outside the casing of described each isolating switch, also be provided with anchor hole on the tank wall, when three independently isolating switch is arranged side by side, adjacent isolating switch be bonded into the isolating switch that one constitutes three stations pass the anchor hole of adjacent isolating switch by peg after.
The beneficial effects of the utility model are that the isolating switch with each station of tri-station isolating switch is provided with separately, and novel structure is small and exquisite, do not take up space, and each isolating switch is simple in structure, and is easy to operate, can be in working order.Suit arbitrarily between isolation and the ground state, because the outer integral sealing insulation of isolating switch can not influence operator's use, fail safe improves greatly, can satisfy simultaneously in underground buried and use under water.
