Room is connected with leading-out terminal at the top of the vacuum interrupter, and the outer wall of the vacuum interrupter and upper leading-out terminal is coated with
Heat sink, the bottom of the heat sink are connected with moved end, and the bottom of the moved end connects guide sleeve, and the bottom of the guide sleeve connects
It is connected to transmission storehouse, the inner cavity in the transmission storehouse is longitudinally connected with insulated pull rod, and the top of the insulated pull rod is connect with guide sleeve,
The heat sink, moved end, guide sleeve and the outer wall in transmission storehouse are coated with epoxyresin insulator, the epoxyresin insulator
Outer wall be coated with silicone insulation body, thread protrusion, the silicone insulation are respectively connected at left and right sides of the silicone insulation body
The right side wall middle-end of body is plugged with lower wire end.
Preferably, the guide sleeve is regular hexagon guide sleeve.
Preferably, the heat sink is concordant with the right side port of upper leading-out terminal.
Preferably, the tip of the thread protrusion is polished into dome.
Compared with prior art, the utility model has the beneficial effects that the utility model utilizes heat sink by vacuum extinction
Indoor temperature exports in air, reduces the temperature in vacuum extinction room, guarantees the vacuum circuit breaker energy in vacuum extinction room
Enough operations steady in a long-term, and silicone insulation body is coated on the outer wall of epoxyresin insulator, compound inslation is realized, is insulated
Level greatly improves, and thread protrusion is arranged in silicone insulation external surface, increases creepage distance of insulation, improves pole
Insulating capacity.
