Description
Technical field
The utility model relates to the pole of ring main unit, particularly a kind of middle totally-enclosed pole of solid of pressing AC distribution solid insulation ring main unit.
Background technology
In the prior art, pole is that the conductive pieces that vacuum interrupter is relevant with circuit breaker is embedded into this type of epoxy resin simultaneously and easily forms pole in the cured solid insulating material, makes whole circuit breaker polar become as a whole parts.Prior art mostly just is to be cast in vacuum interrupter and relevant conductive pieces together, but tri-station isolating switch is but had no idea and vacuum interrupter is cast in together, has so just seriously hindered the development of solid cabinet truly.
Summary of the invention
Relatively poor for the insulating capacity that overcomes existing solid insulation ring main unit, degree of protection is lower, have the deficiency of potential safety hazard, the utility model provides a kind of totally-enclosed pole that insulating capacity, degree of protection are higher, effectively eliminate safe hidden trouble that promotes.
The utility model solves the technical scheme that its technical problem adopted:
A kind of totally-enclosed pole; Comprise poured with epoxy resin piece, vacuum interrupter and vacuum interrupter; Vacuum interrupter and vacuum interrupter are set in the poured with epoxy resin piece, and the fixed contact of said vacuum interrupter is connected with the first turnover thread casing, and the said first turnover thread casing is positioned at the side of said poured with epoxy resin piece; The moving contact of said vacuum interrupter and the interlock of first pull bar; The quiet end of said vacuum interrupter is connected with the second turnover thread casing, and the said second turnover thread casing is positioned at the side of said poured with epoxy resin piece, the moved end of said vacuum interrupter and the interlock of second pull bar; The moved end of said vacuum interrupter is connected through being flexible coupling with the moving contact of said vacuum interrupter, and said poured with epoxy resin piece is all stretched out in the upper end of said first pull bar, second pull bar.
Further, the moved end of said vacuum interrupter is connected with the experiment terminal, and said experiment terminal is positioned at the side of said vacuum interrupter, and the test splice of said experiment terminal stretches out said poured with epoxy resin piece.
Said vacuum interrupter is three station vacuum interrupters.
Said vacuum interrupter is vacuum circuit-breaker or vacuum load switch.
The beneficial effect of the utility model mainly shows: the number of parts of pole reduces in a large number, and simple structure has improved the reliability of circuit breaker greatly; Because vacuum interrupter and vacuum interrupter are embedded in the solid material, so need not do any further processing, pole can reach very high dielectric strength; After vacuum interrupter and vacuum interrupter were embedded in solid material, external environment was eased down to minimum to the influence of the vacuum interrupter of pole.
