Abstract
The utility model relates to a fixed vacuum switch cabinet with a by-pass bus, used in a power transmission and variation system. The utility model is characterized in that a bus room is positioned at the front side of the upper part of a cabinet body; a vacuum switch room is positioned at the middle part of the cabinet body; a by-pass bus room is positioned at the front side of the lower part of the cabinet body; a cable room is positioned at the back side of the lower part of the cabinet body; a bus in the bus room are connected with a cable head by passing through a isolated knife switch, a vacuum switch, a current transformer and an outlet line knife switch; a by-pass bus in the by-pass bus room is connected with the cable head by passing through a by-pass knife switch. The utility model has the advantages of reasonable layout of the cabinet body, compact structure, small occupation of land and convenient vacuum switch inspection and running supervision.
Description
The utility model relates to a kind of fixed vacuum switch cabinet of band hospital bus bar that is used for the defeated change system of electric power.
The band hospital bus bar stationary cabinet of the more use of power supply department at present, its structure are to add the secondary cabinet of bypass behind general stationary cabinet, and it is too high deeply that cabinet is crossed, take up an area of greatly, by-pass line passes through the cabinet rear portion, and is influential mutually when bypass hotline maintenance switch, make difficulty of maintenance, also be not easy to operating supervision.
It is rationally distributed that the purpose of this utility model provides a kind of cabinet, and compact conformation takes up an area of little and is convenient to the fixed vacuum switch cabinet of band hospital bus bar of switch maintenance and operation monitoring.
The technical solution of the utility model is, switch cabinet body is divided into bus-bar room, vacuum interrupter chamber, hospital bus bar chamber and cable vault, it is characterized in that: bus-bar room is positioned at front side, cabinet top, vacuum interrupter chamber is positioned at the cabinet middle part, the hospital bus bar chamber is positioned at the cabinet lower front side, the cable vault is positioned at cabinet bottom rear side, three-phase bus in the bus-bar room is connected with the vacuum switch that is positioned at the vacuum interrupter chamber front portion by the last isolation switch that is installed in the vacuum interrupter chamber top, the busbar of vacuum switch output enters the cable vault by the current transformer between vacuum interrupter chamber and cable vault, and is connected with cable end at the bottom of the cabinet by the outlet disconnecting link in the cable vault; The indoor three-phase hospital bus bar of hospital bus bar is connected with cable end by being installed in the indoor by-pass knife switch of hospital bus bar.Described outlet disconnecting link and by-pass knife switch can be all-in-one-piece bilateral disconnecting links, its pedestal is installed between hospital bus bar chamber and the cable vault, by-pass knife switch and outlet disconnecting link are installed in the pedestal both sides respectively, each mutually shared one punching insulated leg that crosses the pedestal both sides of the output of by-pass knife switch and outlet disconnecting link, and be connected as a single entity by the electric conductor that is through in this insulated leg, cable end is connected with output:
The utility model has the advantages that, because vacuum switch places the cabinet middle part, and hospital bus bar is positioned at below the vacuum switch, integral layout is reasonable, and compact conformation takes up an area of little, vacuum switch and hospital bus bar mutually noninterfere simultaneously, both be convenient to operating supervision, when inspection switch, also door before and after the cabinet middle part can have been opened simultaneously, be very easy to the maintenance of switch.In addition, the monolithic construction of outlet and by-pass knife switch, connecting link is few, makes cabinet body structure compact more.
Below in conjunction with accompanying drawing specific embodiment of the utility model is described further.
Fig. 1 is the structure chart of the utility model embodiment.
As shown in Figure 1, three-phase bus 3 in front side, the cabinet 1 top bus-bar room 2 are connected by last isolation switch 4 and vacuum interrupter chamber 5 interior vacuum switches 6, vacuum switch 6 is connected with cable end 10 with cable vault's 8 interior outlet disconnecting links 9 by current transformer 7, three-phase hospital bus bar 12 in the hospital bus bar chamber 11 is connected with cable end 10 by by-pass knife switch 13, by-pass knife switch 13 and outlet disconnecting link 9 shared pedestals among the figure, their output is connected as a single entity by the electric conductor in the punching insulated leg 14.When the switch cubicle operate as normal, last isolation switch 4, vacuum switch 6 and outlet disconnecting link 9 are in closure state, and switch cubicle is powered to cable end 10 outputs through vacuum switch 6 by bus 3; When need maintenance vacuum switch, last isolation switch and outlet disconnecting link disconnect, by-pass knife switch 13 closures, and switch cubicle is directly exported power supply by hospital bus bar, the front and back door inspection switch easily just in the middle part of the cabinet is opened in this moment vacuum switch and hospital bus bar mutually noninterfere.
