Description
Technical field
The utility model belongs to electric system repair apparatus technical field, particularly relates to the charged phase checking device of a kind of cable.
Background technology
In electric system, after the maintenance of cable installation complete or cable, breakdown repair, must nuclear phase be carried out, thus avoid because phase place is not inconsistent the serious problems caused.In addition; high-voltage cable middle joint ground wire needs cross interconnected in certain sequence; thus reduce induced voltage and the circulation of cable metal aluminium sheath; but when there is mistake in the intermediate head ground wire order of connection; the induced voltage of cable metal aluminium sheath and circulation will be caused during operation to increase; result causes cable body temperature to rise; thus cable insulation material is caused damage; and superpotential serious time also likely burn out overvoltage protection device or earthing box for electric cable, thus to the person and equipment produce high risks.
Summary of the invention
In order to solve the problem, the purpose of this utility model is to provide a kind of cable charged phase checking device.
In order to achieve the above object, the charged phase checking device of cable that the utility model provides comprises two magnet-type alien frequencies marking current mutual inductors, alien frequencies signal generator and alien frequencies signal receivers; Wherein magnet-type alien frequencies marking current mutual inductor is the square shape structure be made up of the first half and Lower Half, inside is provided with strong magnet, a surface of contact of the first half and Lower Half is formed with a projection, another surface of contact is formed with a connecting hole, and the first half is used in combination with the surface of contact with connecting hole in the surface of contact of projection and Lower Half, and the lateral surface of the first half is provided with a connection terminal simultaneously; Connection terminal on a magnet-type alien frequencies marking current mutual inductor is connected with alien frequencies signal generator by signal wire, and the connection terminal on another magnet-type alien frequencies marking current mutual inductor connects with alien frequencies signal receiver.
The inside dimension of described alien frequencies marking current mutual inductor is 6.2 × 5.5cm, and external dimensions is 9.2 × 11.5cm, and thickness is 3cm.
The charged phase checking device of the cable that the utility model provides has following beneficial effect: adopt alien frequencies signal to export, do not affect cable normally to run, can not have an impact safely to major network, in power failure or correct judgment phase cable can not identified well under power-off condition.In addition, this device also have structure simple, realize easily, use easy to operate and low cost and other advantages.

Embodiment
Below in conjunction with the drawings and specific embodiments, the charged phase checking device of cable that the utility model provides is described in detail.
As shown in Fig. 1-Fig. 3, the charged phase checking device of the cable that the utility model provides comprises two magnet-type alien frequencies marking current mutual inductors 1, alien frequencies signal generator 2 and alien frequencies signal receivers 3; Wherein magnet-type alien frequencies marking current mutual inductor 1 is the square shape structure be made up of the first half 4 and Lower Half 5, inside is provided with strong magnet 6, a surface of contact of the first half 4 and Lower Half 5 is formed with a projection 7, another surface of contact is formed with a connecting hole 8, and the first half 4 is used in combination with the surface of contact with connecting hole 8 in the surface of contact of protruding 7 and Lower Half 5, and the lateral surface of the first half 4 is provided with a connection terminal 9 simultaneously; Connection terminal 9 on a magnet-type alien frequencies marking current mutual inductor 1 is connected with alien frequencies signal generator 2 by signal wire, and the connection terminal 9 on another magnet-type alien frequencies marking current mutual inductor 1 connects with alien frequencies signal receiver 3.
The inside dimension of described alien frequencies marking current mutual inductor 1 is 6.2 × 5.5cm, and external dimensions is 9.2 × 11.5cm, and thickness is 3cm.
The charged phase checking device using method of the cable now provided by the utility model is described below:
When needs carry out nuclear phase to cable 10, under cable 10 charging operation or interruption maintenance situation, first the first half 4 of a magnet-type alien frequencies marking current mutual inductor 1 and Lower Half 5 are separated, then the projection 7 on surface of contact is utilized the first half 4 and Lower Half 5 to be combined with coordinating of connecting hole 8 and be stuck in outside one end of cable 10, afterwards another magnet-type alien frequencies marking current mutual inductor 1 is stuck according to the method described above the outside other end of cable 10, then two magnet-type alien frequencies marking current mutual inductors 1 are connected with alien frequencies signal receiver 3 with alien frequencies signal generator 2 respectively by signal wire, alien frequencies signal generator 2 is utilized to produce the signal of 1HZ-30HZ afterwards, at this moment this signal the loop being sensed cable 10 by coupled alien frequencies marking current mutual inductor 1 will transfer to the other end of cable 10, the Signal reception sensed to be transferred on alien frequencies signal receiver 3 and to show by another alien frequencies marking current mutual inductor 1 again, staff can judge correct phase cable by amplitude change.
