Technical field
The utility model relates to a kind of electric component, especially for the special-purpose junction block of high voltage isolator, belongs to the switching technique field.
Background technology
Isolating switch is a kind of can the circuit idling cut-off or the pass that link to each other being closed, and the mechanical switching device of electrical isolation fracture can requirement according to the rules in the separating brake position be provided.The isolating switch junction block is that current-carrying part is played critical elements fixing, the installation effect, and junction block is installed on the post insulator, partly is connected with isolation switch contact or fingertip.High voltage isolator junction block commonly used comprises parts such as junction block shell, gear cover, axle sleeve, conductive strips, fixed head; Its structure is referring to Fig. 3; Screwed hole is arranged at the junction block bottom; Can be fixed on the insulator through bolt, the outstanding position of shell clamps assembling with fixed head independently with the fingertip conductive arm, forms firm fingertip current-carrying part; Form main galvanic circle by conducting rod, conductive strips, junction block shell, independent stationary plate, conductive arm, the junction block shell is as main power consumption original paper.The problem that the high voltage isolator junction block of this common structure exists is following: the inner tie point of junction block is more; Shell is under the through-flow operating state as the part of galvanic circle for a long time, the long-time through-current capability that can influence junction block useful life and whole galvanic circle of using.
The utility model content
The utility model is used to overcome the defective of prior art and provides a kind of high voltage isolator that improves junction block serviceability and galvanic circle through-current capability special-purpose junction block.
The alleged problem of the utility model is that following technical scheme solves:
The special-purpose junction block of a kind of high voltage isolator; Comprise shell, conducting rod, conductive strips and curved connecting plate in the formation, conductive strips and conducting rod are positioned at shell, and the two is fixed; Its special feature is: the inwall of said shell is provided with insulating barrier; The shell external part is provided with the external part insulating barrier, and the said curved connecting plate medial extremity that is positioned at housing is connected with conductive strips, is positioned at the outer curved connecting plate external part of housing and is provided with fingertip conductive arm fixed bolt hole.
