Q: How to distinguish stealing from electricity: 1, carefully check the internal wiring of this new watch, whether or not the connection is off or short circuited.2, check the line of the meter to see if the user has other circuitry to bypass the meter.3, check the line, we must ensure that the entire line intact, there is no "private", "random" phenomenon.

Q: A selection table clamp type table: Clamp meter before the measurement was estimated the size of the current, and then decide which range. If you can not estimate, you can use the maximum range file, and then appropriate to smaller, to accurate readings. Small current cannot be used to measure high current. To protect the instrument from damage.

Q: How to maintain and maintain the communication and power room?: AC / DC clamp type meter. AC / DC clamp meter as the daily maintenance work is one of the essential test tool, mainly used to test the voltage, current, frequency and other related parameters, it has high resolution and precision testing and more testing function. At present, the maintenance personnel usually use the FLUKE of the United States F337 AC / DC Clamp Meter (RMS), and Silicon Valley communication production of SGT-11A and SGT-12B single and double jaw clamp type table, this kind of instrument with large diameter and small jaw electrical test resolution and high precision, accurate measurement, current flow the characteristics of. At the same time, the manual design of this kind of pliers is very suitable for the occasions with small space. Noise meter. The noise meter is mainly used to test the pulse component of rectifier equipment and DC converter output voltage, that is, noise voltage. At present, the noise meter in the market is mainly analog and digital. The analog noise meter is mainly JH5151 of state owned Jianhua instrument factory. Although it is larger and heavier, it has many testing indexes and high accuracy. Digital noise meter mainly has FZY-120 and FZY-120A, it has light and easy, portable, simple test, visual display and so on. At present, maintenance personnel can choose to use according to their favorite.

Q: Measurement of AC and DC dual-use electrical instruments, overload ability of the instrument for?: This is the moving coil instrument, which means the electronic device, do not make a mistake.

Q: How to measure the current and voltage clamp meter?: (1) in the measuring line, to clamp meter data of zero, to prevent errors in subsequent measurement.(2) after determining the voltage of the line to be measured, select the appropriate range.

Q: A table can be used to measure the DC current?: The current transformer produced by the clamp meter, can only measure the AC current, accurate measurement of sine wave current near 50Hz only, cannot measure the DC current.

Q: Automatic tripping of circuit breaker often, this is why, what to do?: Second reason is the load, cite a simple example, if the current line is 200A, and the frame current circuit breaker 100A, access motor, the normal line, but for the circuit breaker has obvious overload, it will cause the circuit breaker has been tripping. As for load tripping, the most common is that in our daily life, the current leakage caused by excessive current (such as DZ47le-32 leakage circuit breaker) tripped. Generally speaking, tripping due to load should not occur, and the parameters such as rated current of the line should be known when the model is selected. Here is also added a little knowledge: if the circuit breaker in the starting instant trip occurs, is caused by short-circuit. In the start process, tripping is caused by overload.

Q: The power consumption of the same load, different power motors?: When the 380V/55KW motor is full, the current is 100A. You only have 70A now, which means that your load is only about 35KW37KW motor can be used instead of the current slightly less than 70A, but not much. Nothing changed, slightly less. Idle work will be much smaller.

Q: What is the cause of the tripping of the two phase motor?: Check the current with a clamp meter to see if it is overload. Measure the resistance of the two windings

Q: Generator carbon brush fire how to deal with?: Carbon brush and slip ring should be inspected every day. Main inspection items are:(1) the wear length of carbon brush should not exceed 2/3. When the wear length of the carbon brush exceeds the 2/3 (i.e. the top of the carbon brush is at the same level as the top of the brush holder), it must be replaced.(2) carbon brush without sparking. When the carbon brush starts to spark, you must find out the reason and remove it in time.(3) there is no offset slip ring outside the carbon brush, and the edge of the carbon brush is not cracked.(4) the brush brush is connected with brush holder and carbon brush, without heating and touching brush holder.(5) the carbon brush has no pulsation, shaking or sticking in the brush holder.(6) regularly measure the current of each carbon brush evenly with the DC clamp type meter, and measure the carbon brush with the infrared thermometer. If abnormal, it should be replaced in time.(7) the spring pressure is normal, without deformation and fracture. Normal, the pressure on each carbon brush should be uniform and stable, the unit pressure is usually between 1.1kg ~ 2.5kg, the uneven pressure difference between the carbon brush should be less than 5%.(8) the distance between the brush holder and the slip ring conforms to the specified value. Distance between brush holder and slip ring of generator: 2.5 ~ 3 mm, distance between main brush holder and slip ring: 2~4 mm.
