Abstract

The utility model discloses an ultra-short-type solid encapsulation pole column. The pole column comprises an insulation shell, a vacuum arc-extinguishing chamber, a wire inlet column and a wire outlet column. The vacuum arc-extinguishing chamber is clamped in the middle of the insulation shell. An operation combination or disconnection pull bar is installed in the vacuum arc-extinguishing chamber. The pull bar is connected with a lower-portion moving end of the vacuum arc-extinguishing chamber. The wire inlet column is inserted into the insulation shell from an upper portion of the insulation shell and is connected with an upper end of the vacuum arc-extinguishing chamber. The wire outlet column supports on a lower portion of the insulation shell and forms copper flexible connection and is connected with the lower-portion moving end of the vacuum arc-extinguishing chamber. A central section of one insulation connecting rod is hinged to lower portion of the insulation shell. One end of the insulation connecting rod is hinged with a lower end of the pull bar, wherein the end of the insulation connecting rod is close to the insulation shell. The other end of the insulation connecting rod is hinged with an over travel rod, wherein the other end of the insulation connecting rod is far away from the insulation shell. By using the pole column of the utility model, a length is short; installation is convenient; a creepage distance of a wire inlet end and a wire outlet end is long, which is good for miniaturization of a switch cabinet.

Description

A kind of pole of ultrashort type
Technical field
The utility model relates to the pole that circuit breaker is used, especially a kind of pole of ultrashort type.
Background technology
Pole is the main parts of vacuum circuit-breaker, existing common pole is that ZL201120027560.8, name are called the utility model patent of " pole " if disclosed a patent No. on August 31st, 2011, it comprises epoxy package, vacuum interrupter, upper outlet terminal, lower wire end, vacuum interrupter is fixed in epoxy package, upper outlet terminal and lower wire end are arranged on the same side of epoxy package, the operation part of vacuum interrupter be arranged on vacuum interrupter below.This pole existing problems are that length is longer, and inconvenience is installed, and make simultaneously the creepage distance between circuit less, are unfavorable for improving insulation effect and make the switch cubicle miniaturization.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of pole of ultrashort type, and its length is short, easy for installation, and the creepage distance of end of incoming cables and leading-out terminal is long, is conducive to the miniaturization of switch cubicle.
For achieving the above object, the technical solution of the utility model is: a kind of pole of ultrashort type, comprise insulation shell, vacuum interrupter, the inlet wire post, outlet column, vacuum interrupter is clipped in the centre of insulation shell, the pull bar that vacuum interrupter is equipped with an operation combination or disconnects, the moved end, bottom of described pull bar and vacuum interrupter is connected, the inlet wire post stretches into insulation shell and is connected with the vacuum interrupter upper end from the top of insulation shell, the bottom that outlet column is supported on insulation shell is flexible coupling and is connected with the moved end, bottom of vacuum interrupter by copper, the middle part of one insulated connecting rod is hinged on the bottom of insulation shell, insulated connecting rod is hinged near an end of insulation shell and the lower end of pull bar.
Further improve, described insulated connecting rod is hinged with an excess of stroke bar away from the other end of insulation shell; On described excess of stroke bar, be connected with excess of stroke stage clip.To facilitate the operation of vacuum interrupter.
Further improve, the side of described outlet column is provided with earthing contact.Facilitate the ground connection operation of outlet column.
Further improve, the top of described inlet wire post is provided with a flat-shaped copper contact, and a hinged through hole is arranged on copper contact.Facilitate the disconnecting link of inlet wire post and isolating switch directly hinged.
Further improve, on described outlet column, be processed with a plurality of connecting through holes.Facilitate outlet column to be connected with the output bus.
Further improve, the middle and upper part of described insulation shell is provided with a circle and is roughly square flange; On two sides of described flange, be embedded with metal nuts.Both facilitate the installation of whole pole, improved again insulation and isolation effect between inlet wire post and outlet column.
The utility model is hinged on the bottom of insulation shell by the middle part of an insulated connecting rod, insulated connecting rod is hinged near an end of insulation shell and the lower end of pull bar, make the operating mechanism of vacuum interrupter can be in the side of vacuum interrupter, than the traditional operation mechanism be in below vacuum interrupter, whole pole height is shortened dramatically; While inlet wire post stretches into insulation shell and is connected with the vacuum interrupter upper end from the top of insulation shell, the bottom that outlet column is supported on insulation shell is flexible coupling and is connected with the moved end, bottom of vacuum interrupter by copper, inlet wire post and outlet column are in the upper-lower position of insulation shell like this, strengthened the creepage distance of end of incoming cables and leading-out terminal, save the insulator that supports outlet column, facilitate the layout of whole pole in switch cubicle to install, be conducive to the miniaturization of switch cubicle.
Further, the leading-out terminal of pole, with grounding contact, has the insulation flange to make the creepage distance between end of incoming cables and leading-out terminal long between end of incoming cables and leading-out terminal, and the inlet wire post has flat-shaped copper contact, the convenient isolation switch of installing.
