Abstract
The utility model relates to a fixed switch device used for high-voltage power transmission. The utility model is characterized in that a bottom rack of a breaker is provided with rolling wheels, and simultaneously, the relevant position of the bottom of a cabinet body is provided with tracks; the three phase wire inlet end and the wire outlet end of the breaker are respectively connected with a three phase wire inlet contact and an electric conducting row through a duck mouth type one-shot plug, and an isolating switch is arranged on the lower part of a bus bar room; the isolating switch is provided with a three-phase main cutter shutter, a three-phase grounding contact is arranged on the cabinet body, and the position of the-phase grounding contact corresponds to the position of the main cutter shutter. The utility model has the advantages of convenient installation, test and maintenance, compact structure for the cabinet body, reasonable structure and high safety.
Description
The utility model relates to a kind of fixed switchgear that is used for high voltage power transmission and transforming.
The present fixed switchgear that generally adopts, its circuit breaker fixed installation, it is all very inconvenient to install, test, overhaul.In addition, the isolating switch of its use has operator lock and independent ground connection disconnecting link respectively, and volume is bigger, and it is corresponding bigger that cabinet is taken up room, and makes blocking mechanism complicated more, and misoperation easily takes place, and security reliability is poor.
The purpose of this utility model is, a kind of compact conformation is provided, and takes up an area of fewly, install, test, maintenance be convenient, and fixed switchgear safe in utilization.
The technical solution of the utility model is, this fixed switchgear cabinet front upper place is the control room, the cabinet back upper place is a bus-bar room, circuit breaker is installed in the cabinet front lower place, the three-phase end of incoming cables of circuit breaker connects with the isolating switch leading-out terminal by the three-phase inlet wire contact that is installed on the insulator, the three-phase leading-out terminal of circuit breaker is by being installed in the three-phase busbar in the insulating sleeve and the current transformer and the outlet cable connection at cabinet rear portion, it is characterized in that, described circuit breaker and cabinet are movable installation, promptly on the circuit breaker underframe, roller is installed, simultaneously track is installed in the relevant position of bottom of cabinet bulk, make circuit breaker pass in and out cabinet along track, the three-phase end of incoming cables of circuit breaker and leading-out terminal are respectively by plug of duck-beak type and above-mentioned three-phase inlet wire contact and busbar grafting; Described isolating switch is installed in the bus-bar room below, its end of incoming cables connects three-phase bus, leading-out terminal connects circuit breaker, this isolating switch has three-phase operator lock, other has the three-phase grounding contact to be installed on the cabinet, its position is corresponding with the separating brake position of operator lock, is combined on the grounding contact when promptly operating the lock separating brake.
The utility model has the advantages that, because circuit breaker adopts movable installation, by track turnover cabinet, thereby install, test, maintenance be very convenient, simultaneously because direct ground connection during isolated switch main disconnecting link separating brake forms grounded circuit, omitted the ground connection disconnecting link, reduced the isolating switch size, not only made cabinet body structure compact more, rationally, simultaneously since isolating switch separating brake and one step of ground connection finish.Misoperation can not take place, the security reliability height.
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
Fig. 1 is a structural representation of the present utility model.
As shown in the figure, this fixed switchgear cabinet 1 front upper place is control room 2, the cabinet back upper place is a bus-bar room 3, circuit breaker 4 is installed in the cabinet front lower place, the three-phase end of incoming cables of circuit breaker connects with isolating switch 7 leading-out terminals by the three-phase inlet wire contact 6 that is installed on the insulator 5, and the three-phase leading-out terminal of circuit breaker connects with the current transformer 10 and the outlet cable 11 at cabinet rear portion by the three-phase busbar 9 that is installed in the insulating sleeve 8.Circuit breaker 4 is movable installation with cabinet 1, roller 12 promptly is installed on the circuit breaker underframe, simultaneously track 13 is installed in the relevant position of cabinet 1 bottom, make circuit breaker pass in and out cabinet along track, the three-phase end of incoming cables of circuit breaker and leading-out terminal are pegged graft by plug of duck-beak type 14 and three-phase inlet wire contact and busbar respectively.Isolating switch 7 is installed in bus-bar room 3 belows, its end of incoming cables connects three-phase bus 15, leading-out terminal connects circuit breaker 4, this isolating switch has three-phase operator lock 16, other has three-phase grounding contact 17 to be installed on the cabinet 1, its position is corresponding with the separating brake position of operator lock 16, is combined on the grounding contact 17 when promptly operating lock 16 separating brakes.
