A plurality of layers of flexible copper sheets are connected between the moving contact cutter and a wiring shaft by compression jointing through the bolts. The moving contact cutter mechanism of the track traffic isolation switch has the characteristics of large contact area, high contact pressure, good heat dissipation, high current flow capability and long service life, and is applicable to occasions with the rated voltage being DC1800V and the rated current being 4000A.
Description
Technical field
The utility model relates to the dynamic contact mechanism of isolating switch, rated voltage DC1800V particularly, the movable touch knife device of rated current 4000A.
Background technology
The Chinese patent document discloses a kind of " big dc-isolation switch is with the two guidance contacts devices of major diameter ", and (201110221952.2) its moving contact is the good loop configuration of a major diameter conductivity, and fixed contact is made up of inside and outside two circle fingertips.Electrically contact more reliably behind the combined floodgate, through-current capability is bigger.Its shortcoming is, one of which, the combined floodgate of moving contact and fixed contact can only be translation mode rather than moving contact rotating manner, and as far as motor power, power drive mechanism is complicated, energy consumption is bigger.Its two, fixed contact relies on the spring force of inside and outside fingertip to form the crimp force to moving contact, this crimp force is owing to the loop configuration reason, still exists to electrically contact a problem of reliability shortcoming.And the movable touch knife of existing isolating switch (as 201020617511.5) all is contained in the rotating shaft.Hinged or directly be hinged on the free bearing between rotating shaft and the terminal block, thereby under event of overload, this structure is little at the electric interface of the hinged place of movable touch knife and rotating shaft junction surface and rotating shaft and terminal block, through-current capability is less.
The utility model content
The purpose of the utility model provides that electric interface between a kind of movable touch knife and the terminal block is big, good heat dissipation, track traffic isolating switch movable touch knife mechanism that through-current capability is big.
This novel purpose is achieved in that a kind of track traffic isolating switch movable touch knife mechanism, comprises the movable touch knife that is installed in the rotating shaft, and terminal block is " T " font; Said movable touch knife is welded on forms the movable touch knife parts on the conductive plate; The two ends superimposed by multilayer bar shaped copper sheet and that be bent into " U " font that are flexible coupling are separately fixed on the gusset piece and constitute; Two left and right being symmetrical set that are flexible coupling: the gusset piece at each two ends that are flexible coupling is respectively between the conductive plate and terminal block that are bolted to the movable touch knife assembly.
On the above-mentioned copper sheet that is flexible coupling silver coating is arranged, silver coating is arranged on the movable touch knife.
The above-mentioned copper sheet that is flexible coupling is 100 layers, and every layer of copper sheet thickness is 0.1mm, and the length of every layer of copper sheet * wide is 120mm * 60mm.
Above-mentioned movable touch knife is installed in the insulation rotating shaft.
When movable touch knife inserts pincerlike contact, electric current through pincerlike contact, movable touch knife and double loop be flexible coupling, terminal block forms path.The employing double loop is flexible coupling, and is the needs that satisfied heat radiation, electric life and the mechanical endurance of movable position conductor when movable touch knife rotates.This movable touch knife device is fitted on the GGN-15/4000 track traffic isolating switch, detects institute in July, 2011 in the Zunyi product quality inspection and has passed through type approval test.
Compared with prior art, the utlity model has following characteristics:
1, the movable touch knife that is directed against existing isolating switch is in the little shortcoming of poor electric contact, the through-current capability of its hinged place; Be connected through bolt crimping mode by soft multilayer build-up copper sheet between the utility model movable touch knife and the terminal block; Thereby it is big to have contact area, and contact site pressure is big; Contact resistance is littler, the characteristics that through-current capability is bigger.Simultaneously, the double loop of multilayer build-up copper sheet is flexible coupling for existing articulated structure, has that heat-sinking capability is strong, the advantage of longer service life.
2, simple and practical, be easy to installing/dismounting.
