Description
Technical field
This patent relates to a kind of portable high-pressure cable power detector, for the live detection of cable.
Background technology
In the high voltage supply circuit of colliery, especially the high-tension cable of ore deposit central substation, working section substation is generally laid in cable duct, in the course of work, when carrying out making line box to cable line or carrying out troubleshooting, what frequent needs were definite appraises and decides a certain road cable, and due to the placement location Relatively centralized of cable, cable duct inner cable is more, when the cross-section of cable is larger, staff is difficult in numerous cables, determine charged or uncharged cable.If be the cable that has a power failure by live electric cable erroneous judgement, and directly use saw blade to block cable, certainly will be short-circuited casualty accident.
For guaranteeing that staff accurately judges that whether construction cable is charged, we are according to electromagnetic induction and sensing principle, have made current mode, voltage-type cable power somascope, to detect cable under different situations whether Issues on Static Electrification.
goal of the invention
The object of this patent is to provide a kind of portable high-pressure cable power detector, solves the power detecting problem of high-tension cable.
For achieving the above object, what this patent adopted is technical scheme is: portable high-pressure cable power detector, comprise the handled structural body of band and power supply, power supply is established in structural body, inductive coil, power light, the red green pilot lamp of electric current and control circuit, power light, the red green pilot lamp of electric current is arranged on structural body the same side and exposes structural body, the positive and negative electrode circuit parallel connection power supply pilot lamp of power supply and control circuit, the nearly power end of the positive and negative electrode circuit of power supply is provided with power switch, the signal circuit of the red green pilot lamp of electric current and inductive coil is drawn from control circuit, described control circuit is HDB05580 telemetry circuit plate.
The advantage of this patent is: easy to carry, simple to operate, use safety voltage.Use pilot lamp is warned, the green light when cable is charged, when red time not charged.In numerous cables, can judge that specifically whether a certain cable be charged exactly.

Embodiment
The structure of this patent is as figure: portable high-pressure cable power detector, comprise structural body 4 and the power supply 2 of band jug 1, power supply is established in structural body 4, inductive coil 8, power light 5, the red green pilot lamp 3 of electric current and control circuit 7, power light 5, the red green pilot lamp 3 of electric current is arranged on structural body the same side and exposes structural body 4, the positive and negative electrode circuit parallel connection power supply pilot lamp 5 of power supply 2 and control circuit 7, the nearly power end of the positive and negative electrode circuit of power supply 2 is provided with power switch 6, the signal circuit of the red green pilot lamp 3 of electric current and inductive coil 8 is drawn from control circuit 7, described control circuit 7 is HDB05580 telemetry circuit plate.
We utilize start-stop sensor operating principles, arrange two joint 9 v batteries as the working power of sensor, arrange three LED etc. simultaneously, a power light, another two are carried out electromagnetic conversion when sensor detects the magnetic field of cable line, are lighted by charged pilot lamp by induced voltage.
This device adopts the HDB05580 telemetry circuit plate of KGT15-II type equipment on/off transducer inside, during use, device is directly stuck on cable, open switch and directly can connect working power, now utilize the unbalancedness of three-phase alternating-current powered electric current and the unevenness of cable surrounding magnetic field distribution, when having 50HZ electric current to flow through in operation cable, cable will produce alternation and produce magnetic field around electric current operating path, inductive coil induces the change of cable surrounding magnetic field, thus induced potential is produced in coil, induction electromotive force is through amplifying cable, detector circuit, after comparison loop and signal transacting, output to pilot lamp, changed by indicator light colors, can judge in cable, whether have electric current to flow through.
