Background technology
Clamp on amperemeter is the instrument for realizing powered current detecting using mutual inductance effect to circuit.Clamp on amperemeter includes electricity
Current transformer and ammeter two parts.Wherein current transformer has pincerlike iron core, and the pincerlike iron core can open open and close
Close, when iron core opens, tested wire can enter iron core via the opening for opening, and after iron core is closed, wire is by iron core institute
In being nested in.Now, as shown in figure 1, wire 1001 as current transformer one-level coil, the electric current passed through on wire can be
The secondary coil 1003 that part is wound on iron core 1002 produces faradic current.The ammeter of connection secondary coil 1003
1004 pairs of faradic currents carry out actual measurement, and convert into the current value on tested wire 1001 according to faradic size,
Ammeter 1004 provides the reading of the current value to tested wire 1001.Quilt need not be cut off in the detection process of clamp on amperemeter
The circuit connection of wire is surveyed, the normal operation powered can be kept, had the advantages that easy to use.
Common clamp on amperemeter is by the form that the iron core conformation of expansible and closure is pincerlike head, and utilizes connection ferrum
The clamp handle of core operates the opening and closing of the pincerlike head.But, surveyed when the overhead transmission line that needs to adjust the distance ground certain altitude is run into
During the situation of amount, it is necessary to which engineering staff climbs ladder or electric pole carrys out close enough tested wire, it reduces work efficiency,
There is risk of the hot line job safe distance not enough with operation of ascending a height, increased the probability that contingency occurs.
In order to solve this problem, people have developed Telescopic clip-on ammeter, it is intended to enable engineering staff to stand on ground

Portion, under such structure, if tested wire is located in the horizontal direction substantially, binding clip relatively easily can make wire from bottom to top
Into binding clip opening, but if wire extends or exist the phenomenon of bending coiling in other directions, binding clip is needed with other sides
To clamping wire, inconvenience will be brought to operation, it is desirable to the direction of binding clip and its opening can be adjusted.Four is to run into
The situation of tested wire clustering cannot be processed, and in order to measure current value, binding clip can only sandwich solid conductor, if sandwiching two
Failure can be then measured more than root；And in actual applications overhead transmission line often there is multiple conducting wires clustering and to each other away from
Minimum situation, existing binding clip are difficult to therefrom to isolate solid conductor and are clamped.
