Professional cable recognizer should have the function

To quickly and accurately identify specific cables from a bundle cable, there is a dedicated instrument, professional cable recognition is such an instrument. It is a compact instrument that is relatively simple. So, what kind of cable recognition should also have to quickly and accurately identify a particular cable from a bundle cable, requiring a dedicated instrument, professional cable recognizer is such an instrument.

It is a compact instrument that is relatively simple. So what kind of function should the cable recognition should have? This is the problem that Xiaobian is going to discuss with everyone today. The cable recognizer is a dedicated instrument for identifying a particular cable from a bundle cable.

It is a compact instrument, which is mounted in an aluminum alloy box, consisting of a signal generator, a sensor receiver and connection. In order to accurately identify the cable, it is necessary to add a special signal to the identified cable, which is to be received by a dedicated receiver, using this feature to identify the cable to be found. The generator uses a periodically unipolar voltage pulse into the cable that is identified, which is required to be grounded at the distal end to ensure that there is a sufficiently large current flow over the cable.

The system should be designed to return to the current not to return from the same cable, which can do this, the direction of the pulse current in the cable can be used as an obvious identification standard, and the current flowing only from this cable. All other adjacent cables flow through the return current, but their polarity is opposite. In addition to the actual difference in the current direction, the current amplitude is also an identification feature, flowing out of the current only through a cable, and the return current can pass several cables, which means that the current flowing out of other cables return current big. The task of the receiver is to detect the current direction of the cable current and its size.

To achieve this, the current sensor is used as a sensor with an amplifier and in series in the circuit, the sensor clamps the magnetic field generated by the cable, and the current flowing over the cable inductive voltage, the voltage polarity Decisive by the direction of the current direction and the sensor coil. In order to obtain a voltage polarity in the current direction, test all cables in a bundle cable take the same correct direction. The voltage in the sensor coil is displayed in the header. If the sensor is connected in the above manner, the pointer swing direction can display the current direction, i.e., the cable that is exiting the current flows out of one side, which is the cable to be found.

All other cables flow only return current, and the pointer is partially biased to the other, or there is no pulsat current, the pointer is not deflected. The amplification regulator on the receiver adjusts the signal strength. Professional cable recognizers What we need is that, of course, there is a good accuracy. If the accuracy is not enough, we use it is equal to the white fee, and if it is not accurate, it will affect the later period.

In addition to accuracy, it is to guarantee the life of use. Using a normal voltage current ratio, a grounding resistance table (commonly known“Ground shaker”When measuring the ground resistance, the grounding device through the iron tower should be subsequently subsequently subsequently subsequently subsequently subsequently subjected to measurement; the grounding device of the non-prestressed reinforced concrete pole should be removed from the top of the rod to the lightning line. Measurement. In the initial state of the system, press the DC resistor tester setting button, enter the setup function status, set the material option to unknown, the measurement mode is set to the resistor, the working mode is set to the standard, the measurement speed is set to the standard, press the return button to return Go to the initial state of the system.

With regard to the relevant content of the professional cable recognizer, we will introduce it here today, I hope to help you.
