Background technology
At the beginning of 2008, southern many provinces and regions electrical network has met with freezing rain and snow disaster rarely seen in the history, has brought unprecedented destruction for supply of electric power, safe and stable operation and power transmission and transforming equipment, and economic loss is up to 3.5 hundred million yuan.Protect electricity for anti-ice, the units such as State Grid Corporation of China mobilize ten hundreds of electrical employees, climb up the high artificial deicing of electric tower in shrewd wind, have paid the painful cost of blood and life.
In the recent period, the line ice melting of extra-high voltage DC transmission system method that State Grid Corporation of China proposes, this line ice-melting method, from the main electrical scheme of current conversion station, to increase connecting line and switch, by changing the on off operating mode of respective switch, change the annexation between the converter, strengthen the purpose that the transmission line electric current carries out ice-melt thereby reach.The method can also guarantee that DC transmission system switching between normal transmission of electricity state and ice-melt state, only needing increases a small amount of equipment, can realize the function of active ice-melt in situation about not having a power failure.The equipment such as the connecting line that increases and special key then need again to develop as early as possible.
Summary of the invention
For solving the technical problem of above-mentioned existence, the utility model provides a kind of liftable and horizontal moving high-voltage direct current isolation switch, moving contact adopts two-tube scissor structure, good looking appearance, have good electrical equipment and mechanical performance, and can realize as required lifting and transverse shifting, it is reliable to operate steadily, the divide-shut brake position is accurate, improves ice-melt efficient.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of liftable and horizontal moving high-voltage direct current isolation switch, include moving contact and base, be provided with rotating insulated son and post insulator between described moving contact and the base, described moving contact adopts two-tube scissor structure, also include vertical lift frame and horizontal mobile device, the top of described vertical lift frame is provided with horizontal mobile device, is provided with steel bracket between described horizontal mobile device and the base.
Described two-tube scissor moving contact includes the scissor upper pipe of two-tube parallel connection and the scissor lower pipe of two-tube parallel connection, be provided with grading ring between the scissor upper pipe of described two-tube parallel connection and the scissor lower pipe of two-tube parallel connection, be connected with the pipe synchronous connecting shaft between scissor two pipes of described two-tube parallel connection, two pipes are in crossing condition after connecting, and the scissor lower pipe of described two-tube parallel connection bottom is connected with transmission case.
Moving contact of the present utility model adopts two-tube scissor structure, and good looking appearance has good electric and mechanical performance, and good anticorrosive, earthquake resisting performance satisfy and decide more than the electric current 5000A; Increased the reliable horizontal mobile device that operates steadily in the base bottom, when the switch incomplete phenomena occurring, can finely tune horizontal mobile device and reach desired location; In the bottom of horizontally moving device the vertical lift frame is set, realize lifting and landing to moving contact by the vertical lift frame, the vertical lift frame has the rising limit function, can or drop to relatively accurate position with the moving contact lifting, save debug time, improve the ice-melt operating efficiency.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in detail:
Be depicted as shown in Figure 1 a specific embodiment of the present utility model, include moving contact 2 and base 4, be provided with rotating insulated sub 3 and post insulator 9 between described moving contact 2 and the base 4, described moving contact 2 adopts two-tube scissor structure, also include vertical lift frame 7 and horizontal mobile device 6, the top of described vertical lift frame 7 is provided with horizontal mobile device 6, is provided with steel bracket 8 between described horizontal mobile device 6 and the base 4.So just whole direct-current isolating switch is arranged on the vertical lift frame 7, by lifting and the landing of vertical lift frame 7 realizations to direct-current isolating switch moving contact 2, when moving contact situation not in place occurring, can move by the relative position of regulating between the fixed contact 1 on horizontal mobile device 6 realization direct-current isolating switch moving contacts 2 and the pipe bus, guarantee to close a floodgate accurately and reliably.
As shown in Figure 2, described two-tube scissor moving contact 2 includes the scissor upper pipe 11 of two-tube parallel connection and the scissor lower pipe 13 of two-tube parallel connection, be provided with grading ring 12 between the scissor lower pipe 13 of the scissor upper pipe 11 of described two-tube parallel connection and two-tube parallel connection, be connected with pipe synchronous connecting shaft 10 between two pipes of described two-tube parallel connection scissor 11, two pipes are in crossing condition after connecting, and the scissor lower pipe of described two-tube parallel connection 13 bottoms are connected with transmission case 14.
As shown in Figure 1, the utility model is moved to the lower position of managing bus static contact 1 correspondence, vertical lift frame 7 is with whole direct-current isolating switch lifting, until moving contact 2 arrives the correct position that contacts with fixed contact 1, finish reliable feed motion, connect rear through-flowly, carry out ice-melt work.If there is moving contact 2 and fixed contact 1 cannot not the closing lock or moving contact 2 do not arrive accurate location, regulate horizontal mobile device, make moving contact 2 arrive accurate locations and finish combined floodgate.The shape of moving contact 2 after closing a floodgate similarly is closed scissors, good looking appearance.
As shown in Figure 3, behind the ice-melt end-of-job, moving contact 2 and fixed contact 1 separating brake, vertical lift frame 7 starts whole direct-current isolating switch is dropped to lowest order, and moving contact 2 falls back to initial position simultaneously.
