The handle is connected with the rotating body, the rotating axle and the transmission rack use key connection and both ends of the tension spring are respectively hooked on the transmission rack and a transmission body. The swinging block is fixed on a cover plate by a swinging block axle. The utility model has the advantages of small size, compact structure, strong current passing ability, convenient installation and maintenance and small ground occupying area. The utility model is the new load switch for the reformation of an urban network at present.
Description
The utility model relates to a kind of switch electric product, specifically refers to a kind of two station oil immersed type on-load switches.
On-load switch be a kind of can close (also can under the overlond running condition of regulation) under the normal circuit condition close, carrying and drop-out current and under the unusual loop condition of regulation (as short circuit), the switching device of time loaded current in accordance with regulations.It is to use defeated, controller switching equipment very widely in the modern power systems.Traditional on-load switch is as a controller switching equipment independently, electrical network is connected on the transformer, thus bulky, installation and maintenance expense height.
The purpose of this utility model is to provide that a kind of volume is small and exquisite, compact conformation, three links, conveyance capacity is strong, convenient for installation and maintenance, be installed in the combined transformer box house, with the two station oil immersed type on-load switches of transformer oil as insulation and arc-extinguishing medium.
The purpose of this utility model takes following measure to realize:
The utility model adopts manual spring energy-storage structure, guarantees the design that load can disconnect rapidly and connect.The utility model is made up of operating mechanism and electrical system two parts, A in the power network line, B, C three-phase are connected on respectively in the input wires stake of combined transformer, connect with the static contact group of switch electrical system by lead-in cable, and the static contact group of the other end by switch connects with the coil of transformer, rotated the connecting and disconnecting state of control circuit by the movable contact spring group of switch.Electrical system comprises pedestal, static contact group, movable contact spring group and rotating shaft, and the static contact group is fixed in respectively on the pedestal, and pedestal is an insulator, and the movable contact spring group is fixed in the rotating shaft, between movable contact spring and rotating shaft insulator is set; Operating mechanism comprises handle, rotating shaft, it is characterized in that described handle end is provided with rotor, and rotating shaft one end is provided with gear frame, between gear frame and transmission body extension spring is set, movable centering block is set on the cover plate on pedestal top, and centering block is fixed on the cover plate by swing-block shaft, and centering block can rotate with swing-block shaft.
Embodiment elaborates to the utility model below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the state diagram of the turned position of operating mechanism of the present utility model
Among the figure: 1. pedestal 2. cover plates 3. static contact groups 4. movable contact spring groups 5. handles 6. centering blocks 8. Handle axis 9. rotors 10. gear frames 11. extension springs 12. centering blocks 13. rotating shafts 14. fixed covers
According to embodiment shown in Figure 1:
The utility model two station oil immersed type on-load switches comprise operating mechanism and electrical system two parts composition.Electrical system comprises pedestal 1, static contact group 3, movable contact spring group 4 and rotating shaft 13, and static contact group 3 is individually fixed on the pedestal 1, and pedestal 1 is an insulator.Movable contact spring group 4 is fixed in the rotating shaft 13, rotates with the rotation of rotating shaft 13, and 13 of movable contact spring 4 and rotating shafts are provided with insulator.When the utility model was in running order, the movable contact spring group 4 in the rotating shaft 13 snapped in respectively in the corresponding static contact group 3, makes line current be able to conducting.Pedestal 1 is provided with cover plate 2.Operating mechanism comprises handle 5, rotor 9, gear frame 10, centering block (6,12), extension spring 11 and rotating shaft 13.Handle 5 is provided with Handle axis 8, and Handle axis 8 is fixedly connected with rotor 9, i.e. key connecting.10 of rotating shaft 13 and gear frames adopt key connecting.Extension spring 11 two ends are hooked in respectively on gear frame 10 and the transmission body 9.Centering block (6,12) is fixed on the cover plate 2 by swing-block shaft 7, and centering block (6,12) can be with swing-block shaft 7 rotations.
On the Handle axis 8 of the present utility model fixed cover 14 is set, two station oil immersed type on-load switches is installed on the case shell side wall of combined transformer by fixed cover 14, cover plate 2.
According to shown in Figure 2:
When load current need cut off, rotate counterclockwise handle 5 (Fig. 2-1), Handle axis 8 drives rotor 9 and is rotated counterclockwise simultaneously.Extension spring 11 is stretched and energy storage gradually.When rotor 9 rotated to the position that coincides with gear frame 10, spring was stretched to maximum length (Fig. 2-2).When continuing rotary handle 5, the head circular arc portion of transmission body 9 will be pushed centering block 6, centering block is clockwise rotated around swing-block shaft 7, and promote gear frame 10 and also clockwise rotate, when rotor 9, gear frame 10 were crossed coincidence lines with extension spring 11, energy storage capacity moment of extension spring 11 was released, restore to the original state, also gear frame 10 is moved apace simultaneously to Fig. 2-3 position, because gear frame 10 is and key connecting is adopted in 13 of rotating shafts, rotating shaft 13 is to rotate synchronously with gear frame 10.Thereby make switch be in dissengaged positions.Reverse operating again, then the utility model switch by dissengaged positions to on-state.
Structural design of the present utility model compared with prior art has outstanding advantage: this The novel volume of implementation is small and exquisite, compact conformation, three-phase ganged. Overcurrent capability is strong, with discrete Controller switching equipment is combined in the transformer, and is convenient for installation and maintenance, and floor space is little, is present city The novel on-load switch of electric network reconstruction.
