The insulation mode of vacuum circuit-breaker main conductive circuit has experienced air insulation, compound inslation, solid envelope insulation three phases, and solid sealing type vacuum circuit breaker is called as third generation vacuum circuit-breaker.Third generation insulation mode is a pole, with through epoxide resin automatic pressure gel technology, arc control device and upper and lower leading-out terminal all is encapsulated in epoxy resin layer inside.Third generation insulation mode has not only been simplified the assembly technology of pole; Prevent that vacuum interrupter galvanic circle connecting bolt from becoming flexible owing to what operating vibration caused; Improved reliability; And the outer surface that makes vacuum interrupter do not receive the influence of external mechanical force and external environment condition, further improved the situation of pole Electric Field Distribution.
In the prior art, indoor vacuum circuit-breaker is not good with the outlet seat heat dispersion of pole, and on higher current class, its heat dispersion is further challenged especially; On the other hand; Because the automatic pressure gelation process difference or the difference of mechanical structure; Indoor vacuum circuit-breaker in use often is easy to generate the phenomenon that outlet seat and epoxy resin layer misplace with pole, makes mechanical strength between the two reduce the internal stability of unfavorable pole.
Summary of the invention
The utility model technical problem to be solved is that the heat dispersion that exists to existing pole is not good, the low problem of mechanical strength between outlet seat and the epoxy resin layer, provides that a kind of heat dispersion is superior, the high indoor vacuum circuit-breaker of mechanical strength is used pole between outlet seat and the epoxy resin layer.
For addressing the above problem, the technical scheme of the utility model is:
A kind of indoor vacuum circuit-breaker is used pole; Comprise the vacuum interrupter and the insulated tension pole assembly that are encapsulated in the pole epoxy resin layer; Be connected with the outlet seat on the quiet conducting block of said vacuum interrupter; Be connected with down the outlet seat on the moving conductive rod of vacuum interrupter, the said outer surface of going up the outlet seat is provided with some grooves or tongue.
The indoor vacuum circuit-breaker of the utility model is arranged on the groove on the outlet seat on the pole with the pole utilization or tongue increases the area of dissipation of going up electric conductor in the outlet seat, helps the heat radiation of pole inner conductive body; Simultaneously, groove or tongue the mechanical strength that has improved between last outlet seat and pole inner surface is set, make the pole internal structure more firm.
Preferably, said groove or tongue are arranged on the outer surface of the last outlet seat that contacts with the pole epoxy resin layer.Help combining between firm epoxy resin layer and the last outlet seat, strengthened whole mechanical strength.
Preferably, the excircle of said pole is provided with some groups of limits, is provided with spacing between shirt rim and the shirt rim.The shirt rim the creepage distance that has increased the pole outer surface is set, improve the security performance of pole, and the shirt rim also has the dirty function of anti-soil.
Preferably, said crowd limit is arranged between outlet seat and the following outlet seat, and said crowd limit also is arranged on down between outlet seat and the pole bottom.
