Description
Technical field
The present invention relates to the supply network ring main unit, especially a kind of middle AC distribution solid insulation ring main unit of pressing.
Background technology
The ring main unit of prior art is divided into two kinds of air insulation and SF6 gas-insulateds: air-insulated ring main unit, and it is made up of low-voltage compartment and high pressure compartment; As long as the low-voltage compartment the inside is some secondary meters of dress and control protection component etc.; High pressure compartment the inside is provided with elements such as isolating switch, on-load switch, fuse and earthed switch.Another is a SF6 insulation ring main unit, because the gas SF6 that adopts is carrying out having toxicity behind the arc extinguishing, and easily leaks, metal device casing is long-pending big, to the sealing requirements height, and the processing technology complexity, cause casing cost height, safeguard and detect complexity, degree of protection is also not enough, and electrified body is exposed, be subjected to the erosion of air, dust, easily cause the corrosion of electrified body, reduced the grade of insulation, very easily cause human casualty accident.
Summary of the invention
Press the insulating capacity of AC distribution solid insulation ring main unit relatively poor in order to overcome in existing, degree of protection is lower, have the deficiency of potential safety hazard, the invention provides a kind of solid insulation ring main unit that level in the pieces such as insulating capacity, protection is higher, effectively eliminate safe hidden trouble that promotes.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of solid insulation ring main unit, comprise cabinet, pole is installed in the described cabinet, described pole comprises the poured with epoxy resin piece, vacuum interrupter and vacuum interrupter, at poured with epoxy resin vacuum interrupter and vacuum interrupter are set, the fixed contact of described vacuum interrupter is connected with the first turnover thread casing, the described first turnover thread casing is positioned at the side of described poured with epoxy resin piece, the moving contact of described vacuum interrupter and the interlock of first pull bar, the quiet end of described vacuum interrupter is connected with the second turnover thread casing, the described second turnover thread casing is positioned at the side of described poured with epoxy resin piece, the moved end of described vacuum interrupter and the interlock of second pull bar, the moved end of described vacuum interrupter is connected by being flexible coupling with the moving contact of described vacuum interrupter, described first pull bar, described poured with epoxy resin piece is all stretched out in the upper end of second pull bar, and described first pull bar is connected with operating mechanism with second pull bar.
Further, the moved end of described vacuum interrupter is connected with the experiment terminal, and described experiment terminal is positioned at the side of described vacuum interrupter, and the test splice of described experiment terminal stretches out described poured with epoxy resin piece.
Further again, described pole is installed in the centre position of cabinet, certainly, also can be installed in other positions.
Further, described vacuum interrupter is three station vacuum interrupters.
Described vacuum interrupter is vacuum circuit-breaker or vacuum load switch.
Beneficial effect of the present invention mainly shows: can realize modularized design, but independent assortment between each functional unit cabinet, if the scene once road or a phase pole go wrong, can change on the spot easily.The ring main unit feeder number can increase and decrease at the scene, and is simple in structure, volume is little.
