Abstract
The utility model discloses a cable identification apparatus with overload protection. The cable identification apparatus comprises a transmitter, a receiver, two power supplies, two power connection wires, two GPS antennas and two coupling clamps. The two GPS antennas are respectively connected to the transmitter and the receiver. The two coupling clamps are respectively connected to the transmitter and the receiver. The two power supplies are connected to the transmitter and the receiver through the two power connection wires, and the transmitter and the receiver are respectively provided with a self-recovery fuse. The cable identification apparatus is safe and reliable to use and can carry out the identification of cable identity and path quickly, safely and accurately.
Description
Technical field
The utility model relates to electric power checkout equipment technical field, is specifically related to a kind of cable recognition device that is provided with overload protection.
Background technology
Cable is the important carrier of transmission current, and in real work, it is the very important content of engineering technical personnel and electrician that cable is identified.First, in service at electric wiring, workmen need to confirm the purposes of power cable accurately and quickly; Secondly, when one phase or multinomial short trouble occur cable, determine the trouble spot that cable breaks down; Also have, whether staff wants monitoring equipment constantly normally to move.At present, the apparatus structure of existing detection streamer is comparatively complicated, volume is larger, being not easy to electrician carries, while having affected at the construction field (site) with field work, cable is detected in real time, therefore these are operated in and many times also need staff to adopt simple hand to touch or the eye method of patrolling checks, make the accuracy of cable detection work and detection speed all be difficult to reach gratifying effect.
Summary of the invention
It is a kind of simple in structure that technical problem to be solved in the utility model is to provide, the cable recognition device that is provided with overload protection that practicality is good.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of cable recognition device that is provided with overload protection; comprise one, transmitter, one of receiver, two of power supplys, two of electric power connection lines, two of gps antennas, two of coupling clamps; described two block power supplies are connected to transmitter and receiver by two electric power connection lines respectively; described two gps antennas are connected respectively on transmitter and receiver; described two coupling clamps are connected on transmitter and receiver, at described transmitter and receiver, are equipped with resettable fuse.
Described transmitter and receiver includes a single-chip microcomputer, and described resettable fuse is connected with single-chip microcomputer.
Described resettable fuse is the SMD structure of SMD, quick and easy for installation.
The beneficial effects of the utility model are: the utility model is safe and reliable, can carry out fast the homogeneity of cable and path, safety, exactly identification.
Accompanying drawing explanation
Fig. 1 is that the utility model transmitter connects block diagram.
Fig. 2 is that the utility model receiver connects block diagram.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As Fig. 1, shown in Fig. 2, a kind of cable recognition device that is provided with overload protection, comprise one, transmitter, one of receiver, two of power supplys, two of electric power connection lines, two of gps antennas, two of coupling clamps, two block power supplies are connected to transmitter and receiver by two electric power connection lines respectively, article two, gps antenna is connected respectively on transmitter and receiver, two coupling clamps are connected on transmitter and receiver, at transmitter and receiver, be equipped with resettable fuse, transmitter and receiver includes a single-chip microcomputer, described resettable fuse is connected with single-chip microcomputer, resettable fuse is the SMD structure of SMD, quick and easy for installation.
The utility model mode of operation:
(1) with electric power connection line, connect power supply and instrument, connect gps antenna and clamp (transmitter and receiver);
(2) press the switch of power supply, power supply electrifying, presses the shift knob of instrument, instrument operation, and (note: after transmitter-on, PPS signal lamp starts flicker, after lock semaphore brightens, explanation has searched out signal to start search of satellite; After receiver start, PPS signal lamp starts flicker, and the digital display of the satellite on screen is shown 3-4 and longitude and latitude and shows explanation and searched out signal);
(3) mode of operation of transmitter is transferred to identification GPS pattern, presses firing button, by observing the data identification cable (noting: the direction of two clamps is in the same way) of receiver.
Note: see that data will see a period of time, can not be because of one or two abnormal data influence judgement, as long as data stabilization just can be identified within the scope of normal data, the resistance of having crossed equipment is bigger than normal, belong to normal phenomenon, normal data phase is at 1.75-0.30, and resistance is generally less than 10, and electric current is very large, abnormal data phase, resistance, electric current is beated very large, is easy to identification.
Safeguard:
(1) when clamp uses, should avoid into water, all clamp steeps in water and uses; If got wet in using, should after finishing using, dry clamp, prevent from getting rusty, for the clamp having got rusty, can polish off rusty stain with dry sanding paper;
(2) instrument uses and should be noted waterproof, and as need are sent, please indicate and handle with care, the not backfin energetically of clamp and satellite line, clamp uses answers handle to use, and does not firmly lift clamp connecting line;
(3) receiving the clamp plug process generalized case of launching needn't screw, in order to avoid cause internal wiring rotation to disconnect;
(4) gps antenna, when the process of screw-in, gently revolves and locks after aligning, during back-out, first depresses and exits, and firmly rotation by force, as not loosening in found gps antenna joint, after please screwing, re-uses;
(5) not often plug of electric power connection line is only pulled up when power supply need to charge.
Claims (3)
