This instrument integrates the essence of buried wire detection equipment at home and abroad. It has the characteristics of simple use, energy saving, fast detection speed, high accuracy, accurate positioning, and low price. It is a must for every buried wire user and rural electrician. Few maintenance tools.
First of all, before detection, it is necessary to find out the nature of the leakage fault line and send power to the line. If the insulation is damaged and the line is not short-circuited to the ground, and the line is not short-circuited, the line can be conventionally sent to the line; if the line is short-circuited and the line leakage or the line insulation is normal, some of the lines are broken and the line is leaking, all the lines of the road can be disconnected (Three-wire or four-wire) are connected in parallel to send power to the line in a single phase; if the insulation to the ground is good, and when the inner core is broken and faulty, all good lines and one end of the broken core fault line can be grounded together, and the fault line The other end of the cable sends single-phase power to the fault line.
This instrument requires one person to operate it. Insert the headphone plug into the headphone jack of the instrument, press the switch, and the indicator light is on. Connect the wires on the detection board to the red and black binding posts, and then touch the detection board a few times, and at the same time, you should hear a bang in the earphone, and the machine is normal. Fasten the nailed detection board on the left and right feet of the detector respectively as the two grounding points of the detector, and then the buried wire can be detected.
Detect from one end of the line to the other over the buried wire, and walk slowly forward. In the line section with good insulation to the ground, the earphone is basically silent. When it is close to the fault point (C), the sound gradually increases from small to large to the fault point When (A), the sound is the loudest, when it crosses the fault point to (B), the sound changes from loud to silent, and then can return to the place where the sound is loudest (A), this point is the leakage fault point.
In order to improve the accuracy, when the fault point is detected, the feet of the detector should be as far apart as possible. To reduce the area of the grounding point.
After probing for a period of time, if you find that the indicator light is not bright enough, you must charge it before probing.
The main technical parameters:
The luminous tube displays indicators; the switch volume is adjustable.
Detection accuracy: when the buried depth is 1 meter, the error is 0.1 meter. When the buried depth is 2 meters, the error is 0.2 meters.
Detection length: unlimited.
Detection depth: the maximum depth does not exceed 3 meters.
Detection range: Any fault point can be accurately located when the insulation resistance to ground is below 300KΩ.
Detection environment: The instrument can work continuously in an environment with a temperature of -20°C—+40°C and a relative temperature of not more than 85%.
Configuration: 1 packing box, 1 host, 1 headset, 1 detection board, 1 manual.
