The sealing switch device of the indoor high voltage comprises a wardrobe body compising a bus chamber and a breaker chamber, a disconnecting switch and a breaker. The three-phase input end of the disconnecting switch is positioned above the three-phase output end of the breaker. A pair of vertical pinboard contacts are arranged between the one phase input end of the disconnecting switch and the output end of the breaker; the peripheries of the output end of the breaker and the input end of the disconnecting switch are respectively provided with cylindrical insulated shields; the frame of the breaker is arranged on a movable carriage, and the car frame of the movable carriage is provided with a lifting mechanism used for upward lifting the breaker. The utility model has the advantages of compact structure, small volume, convenient disassembly and assembly of the components and convenient maintenance of the components.
Description
Technical field
The utility model belongs to the high pressure equipment for power transmission and distribution, relates to a kind of indoor high-voltage compound inslation metal enclosed switchgear.
Background technology
Existing indoor high-voltage sealing switch equipment, its cabinet generally are divided into cable vault and the breaker chamber that distributes up and down, between cable vault and the breaker chamber isolating switch are installed, and parts such as vacuum circuit-breaker, lightning arrester, current/voltage transducer are installed in the breaker chamber.General fixed installation or the mobile trolley installation dual mode of adopting of circuit breaker is installed in the cabinet.A kind of sealing switch equipment of mounting means before adopting, the installation of its circuit breaker, dismounting and maintenance be trouble; Adopt the sealing switch equipment of a kind of mounting means in back, its circuit breaker is easy to dismounting and maintenance.But the existing sealing switch equipment that adopts travelling car formula structure circuit breaker, the three-phase output end of its circuit breaker generally is connected with the terminals that are positioned at the cabinet rear portion by the plug-in type contact of horizontal direction, and then is connected with the isolating switch three-phase input end that is positioned at the circuit breaker top by conductive bus bar.The arrangement mode of each parts is unreasonable in the switchgear of this structure, its cabinet, and the space waste is bigger, makes the volume of whole sealing switch equipment bigger, is difficult to the substation that is applicable to that some spaces are less.
Summary of the invention
Technical problem to be solved in the utility model is, provides that a kind of compact conformation, volume are little, the indoor high-voltage compound inslation metal enclosed switchgear easy to disassembly and maintenance of parts.
Indoor high-voltage sealing switch equipment of the present utility model includes the cabinet of being made up of the breaker chamber of the bus-bar room on top and bottom, isolating switch is installed on the dividing plate between bus-bar room and the breaker chamber, circuit breaker is installed in the breaker chamber, it is characterized in that, the three-phase input end of isolating switch be positioned at the circuit breaker three-phase output end directly over, the plug-in type contact of a pair of vertical direction is installed between each isolated switch input terminal and the circuit breaker output, make the circuit breaker output can with the direct socket connection of isolating switch input; The periphery of circuit breaker output and isolating switch input is respectively arranged with the insulating shield of tubular; The framework of described circuit breaker is placed on the billy gate, is equipped with on the vehicle frame of billy gate to be used for hoisting mechanism that circuit breaker is upwards promoted; Described hoisting mechanism comprises two horizontal worm screws that lay respectively at both sides, circuit breaker frame front and back, and worm screw is connected with a hand power shaft that is positioned on the billy gate vehicle frame vertical plane by chain wheel driving mechanism; The rear and front end of every worm screw drives a worm gear, all be wound with one section steel wire tow line in the rotating shaft of each worm gear, one end of every steel wire tow line is fixed in the rotating shaft of a worm gear, the other end of every steel wire tow line is walked around from a movable pulley bottom, is fixed on the fixing point on the billy gate vehicle frame again; Described movable pulley and worm gear are supporting, and it has four, and they are installed on the circuit breaker frame, and lay respectively near four bights of circuit breaker frame.
Indoor high-voltage compound inslation metal enclosed switchgear of the present utility model directly pegs graft circuit breaker output and isolating switch input by the mode that promotes circuit breaker, omitted the connection busbar, make the interior topology layout of cabinet compact and reasonable more, thereby reduced the cabinet volume; In addition and since circuit breaker peg graft finish after, the insulating shield of circuit breaker output and isolating switch input periphery is interlaced, can improve alternate insulation level greatly, has in further reducing its space hold by the mode of dwindling phase spacing.
