Pole is to be simultaneously embedded in epoxy resin solids insulant by conductive pieces relevant with chopper for vacuum interrupter, makes whole circuit breaker polar become overall parts, reduces the dust in the external world, the impact of moisture contamination.Compared with tradition assembled pole, the number of parts of pole reduces in a large number, and the faying surface of conductor is reduced to 3 groups by 6 groups, and connecting screw is reduced to 1 ~ 3 by 8, and simple structure substantially increases the reliability of chopper；Owing to vacuum interrupter is embedded in solid material, so need not do any further process, pole i.e. can reach the highest dielectric strength；After vacuum interrupter is embedded in solid material, the impact of vacuum interrupter is reduced to minimum by the external environment of pole.
Existing vacuum circuit breaker, pole and chopper main box are casings altogether, the installation junction of pole and chopper main box seals only by the O RunddichtringO of an a diameter of 5mm, sealing effectiveness is the most undesirable, and the fault of primary cut-out 60% is insulation fault causes.
Utility model content
This utility model provides outdoor breaker on a kind of post improving insulating properties, and its main purpose is to overcome the defect that the junction sealing effectiveness of existing pole and chopper main box is bad.
For solving above-mentioned technical problem, this utility model adopts the following technical scheme that
Outdoor breaker on a kind of post improving insulating properties, including pole and chopper main box, it is equiped with insulated tension pole in described pole, described insulated tension pole through the junction of pole and chopper main box and is connected sheet connection with being positioned at this chopper main box operating mechanism, described pole is equiped with a silica gel fairlead with the junction of chopper main box, described silica gel fairlead includes integrated external insulation portion and interior insulation division, described external insulation portion is positioned at bottom described pole and between chopper main box, described interior insulation division is between described pole medial wall and insulated tension pole.
Further, described external insulation portion is in the form of a ring, and offering the screw through-hole that a plurality of circular array is arranged on it, a plurality of screws being positioned at described chopper main box sequentially pass through this chopper main box and screw through-hole and are locked together in the bottom of described pole.
Further, described a plurality of screw is six M8 hexagon socket head cap screws.
Further, described interior insulation division is positioned at the inner circumferential side in described external insulation portion, and this interior insulation division is corrugated, and offers a tension rod thru-hole in the middle part of it, and described interior insulation division is set in outside described insulated tension pole by described tension rod thru-hole.
Further, the ripple of described interior insulation division is in the U-shaped ripple alternately connected.
Compared to the prior art, what this utility model produced has the beneficial effects that:
1, this utility model simple in construction, practical, be there is the silica gel fairlead of interior insulation division and external insulation portion by setting, on the one hand the sealing area installing junction of pole and chopper main box is increased, on the other hand pole and chopper main box have also been kept apart, pole and chopper main box is made to respectively become independent small box, realize pole to be not only isolated from the outside, and isolate with chopper main box, improve insulating properties of the present utility model, and reduce the impact of extraneous extreme climate environment.
2, in this utility model, corrugated by arranging interior insulation division, both can increase the insulation area between pole and chopper main box, and the sealing effectiveness between silica gel fairlead and insulated tension pole can have been improved.
