Abstract
An outdoor high voltage permanent magnet vacuum switch disconnector, lower pillar insulation sleeve is fixed on underframe, upper insulation support sleeve is fixed on lower pillar insulation sleeve, permanent magnet mechanism is fixed in lower pillar insulation sleeve, permanent magnet mechanism power output shaft upper end is connected with high strength insulation tie bar, the other end of high strength insulation tie bar is hinged with moving contact rod of vacuum arc chamber, moving contact rod of vacuum arc chamber is electrically connected with compound flange of upper pillar insulation sleeve, vacuum arc chamber is fixed in upper insulation support sleeve, static contact rod of vacuum arc chamber is fixed on input terminal and electrically connected. The utility model is applicable to 50Hz, 12kv outdoor three-phase AC power transmission and distribution line and minitype distribution substation for breaking/closing load current.
Description
(1), technical field
The utility model relates to a kind of outdoor high-voltage permanent magnetism vacuum load switch, is applicable to the usefulness of making deciliter load current in outdoor three-phase alternating current electric line of 50Hz, 12kV and the small-sized transformer and distribution power station.
(2), background technology
At present, domestic still do not have the permanent magnet mechanism that 12kV high pressure out of doors uses and an on-load switch of vacuum interrupter integrative-structure.Traditional vacuum load switch mostly adopts the electromagnetic spring operating mechanism, and adopts the mode of operating mechanism and the discrete installation of vacuum interrupter, thus complex structure, dishevelled appearance, operation troubles rate many, install and take a lot of trouble, lack useful life.
(3), summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides a kind of outdoor high-voltage permanent magnetism vacuum load switch, and its greasy dirt not only simple in structure, no dyes, no energy consumption and easy for installation, reliable, long service life.
The technical scheme in the invention for solving the technical problem is: fixing lower supporting rod insulating sleeve on the underframe, the fixing insulating support sleeve of going up on the lower supporting rod insulating sleeve, at lower supporting rod insulating sleeve internal fixation permanent magnet mechanism, the power output shaft upper end of permanent magnet mechanism connects an end of high strength insulated tension pole, the movable feeler lever of the hinged vacuum interrupter of the other end of high strength insulated tension pole, the movable feeler lever of vacuum interrupter is electrically connected on the composite flange of upper supporting column insulating sleeve by being flexible coupling, vacuum interrupter is fixed in the insulating support sleeve, and the stationary contact bar of vacuum interrupter is fixed and is electrically connected with last input terminal.
The structure of described upper and lower pillar insulating sleeve, permanent magnet mechanism, vacuum interrupter is fixed three covers on underframe, be used for controlling three-phase line.
Owing to adopt vacuum interrupter, permanent-magnet manipulating mechanism, and be fixed in the insulating support sleeve and become one structure, greasy dirt simple in structure, no dyes so it has, the advantage of no energy consumption, easy for installation, reliable, long service life.
(4), description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model schematic front view;
Fig. 2 is the utility model signal left view.
(5), embodiment
Fixing lower supporting rod insulating sleeve 3 on the underframe 1, the fixing insulating support sleeve 8 of going up on the lower supporting rod insulating sleeve 3.At lower supporting rod insulating sleeve 3 internal fixation permanent magnet mechanisms 2, power output shaft 4 upper ends of permanent magnet mechanism 2 connect an end of high strength insulated tension pole 5, the movable feeler lever of the hinged vacuum interrupter 9 of the other end of high strength insulated tension pole 5, the movable feeler lever of vacuum interrupter 97 is electrically connected on the composite flange 6 of upper supporting column insulating sleeve 8 by being flexible coupling, vacuum interrupter 9 is fixed in the insulating support sleeve 8, and the stationary contact bar of vacuum interrupter 9 is fixed and is electrically connected with last input terminal 10.The structure of described upper and lower pillar insulating sleeve 8,3, permanent magnet mechanism 2, vacuum interrupter 9 is fixed three covers on underframe 1.In two-phase or single phase circuit, use and also belong to protection range of the present utility model.The material of described upper and lower insulating support sleeve 8,3 is a fluorine silica gel, is flexible coupling 7 for silver-plated red copper foil.
