Abstract
The utility model relates to the field of exploring cables or transmission lines, in particular to a cable searching instrument which comprises a power supply (1), an ammeter (2), a forcipate ammeter (3), a load (4), a conducting wire (5) and a switch (6). The cable searching instrument is characterized in that two terminals of the power supply (1) are respectively connected with the ammeter (2) and the load (4) by the conducting wire (5) and the switch (6), the ammeter (2) is connected with one end of a cable to be detected by the conducting wire (5), the load (4) is connected with one end of the other cable to be detected at the same side by the conducting wire (5), the conducting wire (5) is connected with the two cables to be detected at the other side, and a detecting ring of the forcipate ammeter (3) is sleeved outside any one cable to be detected. The utility model has the advantages of simple structure, convenient test, accurate judgment and high work efficiency.
Description
Technical field
The utility model relates to exploration cable or transmission line field, is specially a kind of cable and searches instrument.
Background technology
Cable is the electric energy transmitting apparatus of using always, and in order to save the space, cable is that multiply is twisted on the cable testing bridge that together is layed in the cable tunnel mostly.And aging along with the renewal of the carrying out of technological transformation, equipment and cable, it is the operation that often will implement that the renewal of cable is replaced, and at first will block the cable two ends that preparation is removed during replacing.Owing to often laid the cable that multiply is being twined mutually in the crane span structure, and the general job space is also narrower and small in the tunnel, cable very difficult twitch that press together tightly, like this when changing cable, the contact that will judge a certain its two ends of cable when removing waste and old cable just seems that comparison difficulty, particularly some cable are worn a pipe altogether or part is buried ground, and is more apparent unreliable with the way of twitch, easily erroneous judgement, and will need the cable cutting that keeps to make a big impact and lose to production.
Summary of the invention
In order to overcome the defective of prior art, the lookup tool of a kind of simple in structure, easy to operate, accuracy of judgement, applied range is provided, the utility model discloses a kind of cable and search instrument.
The utility model reaches goal of the invention by following technical solution:
A kind of cable is searched instrument, comprise power supply, reometer, pincers type reometer, load, lead and switch, it is characterized in that: two terminals of power supply are connected reometer and load by lead respectively with switch, reometer is connected by an end of a lead and a cable to be detected, load is connected by an end of lead and another cable to be detected of homonymy, connect two cables to be detected with lead at opposite side, the detection ring of pincers type reometer is enclosed within outside any cable to be detected.
A kind of cable is searched instrument, comprise power supply, reometer, pincers type reometer, load, lead and switch, it is characterized in that: two terminals of power supply are connected reometer and load by lead respectively with switch, reometer is connected by an end of a lead and a cable to be detected, load is by lead ground connection, with lead at opposite side cable one an end ground connection to be detected, the detection ring of pincers type reometer is enclosed within outside any cable to be detected.
Described cable is searched instrument, it is characterized in that: load (4) is a resistive load.
Described cable is searched instrument, it is characterized in that: power supply (1) is 24V and following AC power or direct supply.
When the utility model uses, connect as stated above and finish, close a switch, if the cable to be detected at two ends is same, then can constitute current return, reometer and pincers type reometer all have indication, otherwise, do not constitute the loop, reometer and pincers type reometer all do not have indication, can judge easily so whether the cable at two ends is same.
The beneficial effects of the utility model are: simple in structure, and convenient test, accuracy of judgement, high efficiency.
