Formula structure, i.e. three-phase ground are completed using same movable contact spring, and circular hole is provided among movable contact spring and is used for and contiguous block and contact pressure
Adjusting part is fixedly connected, one end rounding, is easy to movable contact spring with being grounded being slidably matched for quiet knife.
It is grounded quiet knife lower end and is provided with screw thread, for being fixedly connected with sleeve pipe, upper end is provided with and treats that movable contact spring slides into closing position
The combined floodgate auxiliary section coordinated when putting with it, it is in beloid wedge structure to be grounded quiet knife combined floodgate auxiliary section.
Contiguous block is in " cuboid " structure, is provided with orthogonal four through holes, the fixation for movable contact spring and bearing
Connection.
Bearing is L-shaped, and side is provided with circular hole and is used to be fixedly connected with handle and contiguous block, and opposite side is provided with circular hole and axle
Pin is rotatably assorted.
The technical program can provide a kind of simple in construction for gas insulation switch cabinet, occupy little space, and cost is low, and electrically
Superior performance is reliable, easy to operation, produces and processes the earthed switch of assembling, effectively reduces the space-consuming of power supply unit, saves
Equipment cost, power grid security, reliability service are ensured, and possess gas-insulated switchgear itself and carry out wireline test experiment
Function.

Embodiment
The technical solution of the utility model is described in further detail with reference to the accompanying drawings and detailed description.
As Figure 1-4, a kind of earthed switch, including side cabinet 15, the fixed mount that is fixedly connected with side cabinet 15
3rd, the bearing 1 that is rotatablely connected with fixed mount 3, the handle 2 being fixedly connected with bearing 1, movable contact spring 7, it is arranged between movable contact spring 7
Contact pressure adjusting part, the ground connection being arranged on movable contact spring 7 are flexible coupling 6, contiguous block 14, set of the fixed movable contact spring 7 with bearing 1
Pipe 16, the fixed quiet knife 5 of ground connection on shroud 16, bearing 1 are rotated coaxially by the fixed mount 3 and the realization of the pivot pin 4, with
It is grounded the combined floodgate of switch, sub-switching operation.
Circular hole, one end rounding are provided among movable contact spring 7, movable contact spring 7 is Integral three-phase structure.Movable contact spring 7 is three-phase
Integral structure, i.e. three-phase ground are completed using same movable contact spring 7, be provided among movable contact spring 7 circular hole be used for contiguous block 14 and
Contact pressure adjusting part is fixedly connected, one end rounding, is easy to movable contact spring 7 with being grounded being slidably matched for quiet knife 5.
