Technical field
The present invention relates to a kind of current sensor, be specifically related to a kind of open type Rogowski coil current sensor being convenient to eminence mounting.
Background technology
Along with the development of Electrical Measurement Technology, current sensor becomes a kind of common current sensing means, the information of tested electric current can be experienced, and will the information experienced be detected, the information being for conversion into electric signal or other desired forms meeting certain standard needs according to certain rules exports, to meet the transmission of information, process, store, display, the requirements such as record and control, wherein Rogowski coil current sensor take electromagnetic induction as mechanism, under the effect of the toroidal magnetic field of change, by the electromotive force sensed by integrating circuit be transformed to be equivalent to survey lead-in wire on electric current export, due to its stable performance, structure is simple, easy to use and more liked to apply more widely independent of tested loop.
But punching Rogowski coil current sensor is jaw type usually, can only manually operation sheet lower or ground connection place tested loop current-carrying conductor on, if product to be tested or drainage thread present position, loop higher, need take ladder climbing or lifting rope aerial operation to mount sensor, this will increase certain job step and flow process and manpower, increases security risk simultaneously.
Summary of the invention
The object of the invention is to the shortcoming overcoming above-mentioned prior art, provide a kind of open type Rogowski coil current sensor being convenient to eminence mounting, user may stand in lower and current sensor of the present invention is hanging to eminence, and simple to operate, and security is high.
For achieving the above object, the open type Rogowski coil current sensor being convenient to eminence mounting of the present invention comprises current sensor, rope, signal transmssion line, main corbel, telescopic internal overarm support, mounting strut, fixed pulley, push pedal and connecting link;
Described mounting strut is hollow structure, telescopic internal overarm support one end is socketed in one end of mounting strut, the other end of telescopic internal overarm support is connected with one end of connecting link, the side of the connecting link other end is connected with one end of main corbel and fixed pulley, connecting link offers draw-in groove vertically, one end of push pedal is connected in described draw-in groove, current sensor is made up of superstructure and substructure, superstructure and substructure are movably connected and connect, superstructure is fixed on the side of the main corbel other end, and substructure is fixed on the side of the push pedal other end;
One end of described rope is fixed in push pedal, and the other end of rope is fixed on the other end of mounting strut after fixed pulley, and signal transmssion line is connected with the output terminal of current sensor.
The travelling block being provided with axle in described draw-in groove and matching with described draw-in groove, travelling block is socketed on one end of axle, and the other end of axle is connected with push pedal.
The junction of described telescopic internal overarm support and connecting link is provided with for push pedal and mount the locating part that strut plays position-limiting action.
Be connected by hinge between described superstructure and substructure.
Described superstructure and substructure are semicircular ring structure.
The present invention has following beneficial effect:
Of the present invention be convenient to eminence mounting open type Rogowski coil current sensor in use, the superstructure of current sensor only need hang up by user, and then move downward by pulling dynamic mounting strut, mounting strut moves downward through rope and fixed pulley drives push pedal to move upward, push pedal can drive substructure and superstructure to be interlocked, thus realize the suspension of current sensor, be convenient to, for standing in lower, current sensor is hanging to eminence, when needs unload current sensor, only mounting strut need be moved upward relative to telescopic internal overarm support, push pedal drives substructure to open under gravity, thus realize the dismounting of current sensor, simple to operate, convenient, operability is extremely strong.
Accompanying drawing explanation
Fig. 1 is structural representation when current sensor 1 fastens in the present invention;
Fig. 2 is structural representation when current sensor 1 is opened in the present invention.
Wherein, 1 be current sensor, 2 be main corbel, 3 be fixed pulley, 4 be push pedal, 5 be connecting link, 6 for mounting strut, 7 be signal transmssion line, 8 for telescopic internal overarm support.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail:
With reference to figure 1 and Fig. 2, the open type Rogowski coil current sensor being convenient to eminence mounting of the present invention comprises current sensor 1, rope, signal transmssion line 7, main corbel 2, telescopic internal overarm support 8, mounting strut 6, fixed pulley 3, push pedal 4 and connecting link 5, described mounting strut 6 is hollow structure, telescopic internal overarm support 8 one end is socketed in one end of mounting strut 6, the other end of telescopic internal overarm support 8 is connected with one end of connecting link 5, the side of connecting link 5 other end is connected with one end of main corbel 2 and fixed pulley 3, connecting link 5 offers draw-in groove vertically, one end of push pedal 4 is connected in described draw-in groove, current sensor 1 is made up of superstructure and substructure, superstructure and substructure are movably connected and connect, superstructure is fixed on the side of main corbel 2 other end, substructure is fixed on the side of push pedal 4 other end, one end of described rope is fixed in push pedal 4, and the other end of rope is fixed on the other end of mounting strut 6 after fixed pulley 3, and signal transmssion line 7 is connected with the output terminal of current sensor 1.
