Abstract
The utility model provides a single-phase voltage transformer with a switch. The single-phase voltage transformer mainly comprises a contact base, a movable contact, a spring touch pin, a guide sleeve, an insulating pull rod, a transmission member, a rotating shaft, a bottom plate assembly, a transformer body, a shell, a flange, a movable sealing ring and an insulator assembly. The rotating shaft is rotated outside the shell, the direction of the rotating shaft is changed, and thus the movable contact is driven to move up and down to connect or disconnect a high-voltage winding with a gas-insulated metal-enclosed switchgear bus. According to the single-phase voltage transformer, the labor hour is saved, the cost is lowered, the operability of a product in testing, detecting and maintaining is improved, the size of products is reduced, and the convenience is brought to transportation and use.

Embodiment
As shown in Figures 1 and 2, a kind of single-phase potential transformer of belt switch, mainly formed by contact base 1, moving contact 2, spring touch finger 3, fairlead 4, insulated tension pole 5, driving member 6, rotation axis 7, base plate assembling 8, device body 9, housing 10, flange 11, dynamic seal ring 12, insulator assembling 13, the single-phase potential transformer of described a kind of belt switch is all-sealed structure, with flange 11 and the fixing also good seal rotation axis 7 of dynamic seal ring 12.
Described rotation axis 7 is in its rotation of the outer control of housing 10, drives driving member 6 runnings, moves up and down thereby drive moving contact 2, realizes conducting and the disconnection of high pressure winding and Cubicle Gas-Insulated Switchgear (GIS) bus.
When Cubicle Gas-Insulated Switchgear (GIS) is finished seasoned experiment, high pressure winding and GIS bus are in conducting state, rotation axis 7 turns clockwise, by driving member 6, insulated tension pole 5 is moved downward, thereby driving moving contact 2 moves downward 4 li of fairleads, will disconnect fully with contact base 1 when moving contact 2 90-degree rotations have arrived certain stroke, make high pressure winding and GIS bus be in off-state and do the power frequency withstand voltage test; Be rotated counterclockwise rotation axis 7 after finishing power frequency withstand test, by driving member 6, insulated tension pole 5 is moved upward, thereby driving moving contact 2 moves upward 4 li of fairleads, when moving contact 2 90-degree rotations arrived certain stroke will with contact base 1 close contact, make high pressure winding and GIS bus be in conducting state, voltage transformer is carried out other test or use.
