Abstract
The utility model relates to a metal live line detector, in particular to a simple metal object live line detector. The technical proposal is that the simple metal object live line detector mainly comprises a power supply, a switch, a resistance, an integrated circuit, a luminescent diode and a sensor, wherein the power supply is connected with the integrated circuit through the switch, the integrated circuit is a counter CD 4017, 14 feet of the counter CD 4017 are connected with the sensor, the sensor is a copper-core electrical wire with an insulating layer, clock signals are formed on the 14 feet of the counter to lead output 11 feet of the integrated circuit CD4017 to drive the clock signal to shine and indicate metal objects to be charged. The utility model has the advantages of simple circuit, smart volume and convenient use, which adopts a high-light luminescent diode to display, is beneficial for on-site operating staffs to quickly judge, timely adopts effective measures, and prevents electric shock accidents.
Description
One, technical field:
The utility model relates to a kind of metal tape electro-detection instrument, the charged detector of particularly a kind of simple and easy metal object.
Two, background technology:
In oil field oil recovery production run, charged metal object very easily takes place in the frequent touch controls cabinet of site operation personnel, motor etc., owing to move under the long-term lowered in field environment of electric equipment such as the low-voltage power distributing cabinet of oil well, motor, its built-in electrical insulation is aging to cause the situation of outer casing electrification to happen occasionally, this situation is more outstanding in rainy season, and site operation personnel's personal safety has been caused very big threat.Generally speaking, the site operation personnel just checks with the pilot pen, because the demonstration of the neon lamp of pilot pen is not obvious, especially under outdoor sunlight, is not easy to especially differentiate.
Three, summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, provides a kind of simple and easy metal object charged detector, is beneficial to the site operation personnel and judges fast, in time adopts an effective measure, and prevents electric shock accidents.
Its technical scheme is: mainly be made up of power supply, switch, resistance, integrated circuit, light emitting diode and sensor, power supply is connected with integrated circuit by switch, described integrated circuit is counter CD4017,14 pin of counter CD4017 connect sensor, sensor is the copper core electric wire of tape insulation layer, 14 pin at counter form clock signal, make the output 11 pin energy driven for emitting lights led lighting of integrated circuit CD4017 counter, and the indication metal object is charged.
The length of above-mentioned copper core electric wire is 8-12cm.
The two ends parallel connection of above-mentioned integrated circuit is used to indicate the common light emitting diode of power supply.
The beneficial effects of the utility model are: circuit is simple, and volume is small and exquisite, and is easy to use, adopts high brightness LED to show, is beneficial to the site operation personnel and judges fast, in time adopts an effective measure, and prevents electric shock accidents.
Four, description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
Five, embodiment:
In conjunction with the accompanying drawings 1, the utility model will be further described, mainly form by power supply, switch, integrated circuit, light emitting diode and sensor, power supply uses the 9V laminated cell, and S is a single-pole single-throw switch (SPST), is used for turning on and off power supply, LED1 is as the power supply indication, use common light emitting diode, LED2 indicates as electric leakage with red high brightness LED.Sensor uses the copper core electric wire of tape insulation layer, and length gets final product about 10CM.Because the input impedance of CMOS integrated circuit is very high, can go out enough voltage at the sensor internal induction, form clock signal at 14 pin, make the output 11 pin energy driven for emitting lights diode (LED) 2 of integrated circuit CD4017 counter luminous, the indication metal object is charged, thereby can judge whether metal object exists leak current fault.
During use, hold instrument, when instrument probe when the metal object to be measured, if metal object is charged, red high brightness LED will be luminous, the expression metal object is charged.
Claims (3)
1, the charged detector of a kind of simple and easy metal object, it is characterized in that: mainly form by power supply, switch, resistance, integrated circuit, light emitting diode and sensor, power supply is connected with integrated circuit by switch, described integrated circuit is counter CD4017,14 pin of counter CD4017 connect sensor, sensor is the copper core electric wire of tape insulation layer, 14 pin at counter form clock signal, make the output 11 pin energy driven for emitting lights led lighting of integrated circuit CD4017 counter, the indication metal object is charged.
2, the charged detector of simple and easy metal object according to claim 1, it is characterized in that: the length of described copper core electric wire is 8-12cm.
