Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of good insulation preformance is provided, electric clearance is little, can guarantee the single phase gas insulation switch device of normal operation under adverse weather condition.
The technical scheme that realizes above-mentioned purpose is: a kind of single phase gas insulation switch device, by casing, the cable vault, the control room, circuit breaker and operating mechanism are formed, operating mechanism is positioned at box outer surface, housing seat is in the cable vault, and fixedly connected with the top, cable vault, cabinets cavity is separated into the bus-bar room and the breaker chamber of relative sealing by dividing plate, be provided with bus tie in the bus-bar room, insulator, Up Highway UHW, Down Highway, connect row, contiguous block and socket, one end of Up Highway UHW is connected with bus tie, the other end is connected with the insulator on top by the contiguous block on top, Down Highway one end is connected with socket by connecting row, the other end is connected with the insulator of bottom by the bottom contiguous block, circuit breaker is positioned at breaker chamber, and fixedly connected with cabinet wall, bus tie is installed on the dividing plate, this bus tie is made up of insulating sleeve and contact rod, contact rod passes insulating sleeve, one end of contact rod is positioned at bus-bar room, the other end is positioned at breaker chamber, and be connected with circuit breaker, all have gas-insulated medium in bus-bar room and the breaker chamber; Be provided with isolation knife in the bus-bar room, isolation knife is made up of dynamic cutter head, quiet cutter head and connecting plate, quiet cutter head has two, one is fixed on the Up Highway UHW, another is fixed on the Down Highway, connecting plate is embedded in the groove of contact rod, and hinged by rivet and contact rod, and dynamic cutter head is installed on the connecting plate by axle and spring.
After adopting technique scheme, bus-bar room and breaker chamber all have gas-insulated medium, have improved insulation property greatly, have reduced electric clearance, the volume of whole cabinet can be dwindled greatly, thereby can reduce floor space, make full use of land resource.Simultaneously, bus, connection row and circuit breaker all are enclosed in the casing of sealing, make it reduced greatly by the influence of natural conditions, guarantee still can work normally under the harsh climate condition.Owing to be provided with isolation knife in the bus-bar room, being provided with of isolation knife can make the operating process of whole switch more reliable, safer again.

Embodiment
The present invention is further detailed explanation below in conjunction with drawings and Examples.
Shown in Fig. 1～9, a kind of single phase gas insulation switch device, by casing 1, cable vault 8, control room 7, circuit breaker 5 and operating mechanism 6 are formed, operating mechanism 6 is positioned at casing 1 outer surface, be used for control to switch, casing 1 is sitting in the cable vault 8, and be connected by screw with 8 tops, cable vault, casing 1 inner chamber is separated into the bus-bar room 2 and the breaker chamber 4 of relative sealing by dividing plate 3, be provided with bus tie 12 in the bus-bar room 2, insulator 11, Up Highway UHW 13, Down Highway 13 ', connect row 15, contiguous block 14 and socket 10, one end of Up Highway UHW 13 is connected with bus tie 12, the other end is connected with the insulator 11 on top by the contiguous block 14 on top, Down Highway 13 ' one ends are connected with socket 10 by connecting row 15, the other end is connected with the insulator 11 of bottom by the contiguous block 14 of bottom, circuit breaker 5 is positioned at breaker chamber 4, and fixedly connected with casing 1 inwall by double-screw bolt, connector 9 is installed on the dividing plate 3, this connector 9 is made up of insulating sleeve 9-1 and contact rod 9-2, contact rod 9-2 passes insulating sleeve 9-1, the end of contact rod 9-2 is positioned at bus-bar room 2, the other end is positioned at breaker chamber 4, and be connected with circuit breaker 5, all have gas-insulated medium in bus-bar room 2 and the breaker chamber 4; Be provided with isolation knife 16 in the bus-bar room 2, isolation knife 16 is made up of dynamic cutter head 16-2, quiet cutter head 16-5 and connecting plate 16-1, quiet cutter head 16-5 has two, one is fixed on the Up Highway UHW 13, another be fixed on Down Highway 13 ' on, connecting plate 16-1 is embedded in the groove 18 of contact rod 9-2, and hinged with contact rod 9-2 by rivet 17, and dynamic cutter head 16-2 is installed in connecting plate 16-1 by axle 16-3 and spring 16-4 and goes up (as shown in figure 10).Dynamic cutter head 16-2 in use is pressed on the quiet cutter head 16-5, and spring 16-4 can provide pressure for dynamic cutter head 16-2.
