Q: Generator carbon brush sparks, how to deal with?: From the following points: 1. check out whether the brush length is too short to cause the lifeline, the pressure is too small not brush contact ring; 2. check the spring pressure pressure is appropriate, if too small will lead to jump 3. check slip ring brush discharge; surface finish, if too much hair will increase the brush contact resistance of spark; 4. check the rotor electrical resistance, ensure the normal, no inter turn short; 5. check whether the oil bearing gap is too large, resulting in rotor slip ring brush runout, radial runout check slip surface is too large. The brush spark causes sparks; 6., whether the brush is the same as before, the brush has a requirement for the conductive current and the friction speed.

Q: Why do you use a multimeter to measure the zero line and ground wire?: 1, multimeter switch to the AC voltage range, should be so multimeter has such a function,2, range from 200mV~750V, the general 200V file, some clamp type table no 200V file can choose a bigger range, the pointer multimeter stalls to dots can choose 10 V ~100V 3, and then the probes were inserted in V /COM (Jack 220V voltage measuring everyday appliances)4, the black pen line around the left circle (see Figure 2-3) of course, the more the better, pay attention: this black pen needle do not touch hands, to prevent electric shock5, right hand with the red pen were measured in the zero line or line, you write down the results of the 2 measurements, the small FireWire, zero line.

Q: 30mA leakage breaker trip home is always with what method to find the leakage point, with clamp ammeters how?: Check the leakage with shaking table or pointer multimeter 10K resistor file. In the case of power failure, the insulation resistance between the fire line and the ground wire of each branch is measured. When there is leakage, the meter will indicate a relatively small resistance value and the insulation will indicate infinity.

Q: I would like to ask the relationship between the power of the water pump motor and the flow of water: As long as the valve is fully opened, the motor is not overloaded, so that the frequency flow can be adjusted by using a flow transmitter or a pressure transmitter with frequency conversion. As long as the setting is good, the automatic control can be realized automatically.

Q: What is the current clamp? What are the main points on ammeter selection?: Simple operation, do not need to test large current circuit can be directly connected. Safety clamp meter, multimeter and insulation resistance meter are analogue and digital two. The detection range of the standard type: AC, DC from 2A to 200A or 400A, also can be detected by 2000A high current products leakage detection; micro current detection and product number mA and the detection of transformer power supply

Q: The reason that the phase current meter of the three-phase asynchronous motor is too low and the other two phases is normal is that it is too normal: It can also be used to measure the faults at the far end or the proximal end of each phase. If the current balance of each phase is unbalanced, the problem of eliminating the current transformer is the problem of the motor

Q: Is there a caliper meter that can measure direct current?: Magnetic balance type current sensor called compensation sensor, namely the primary current Ip generated in the magnetic core premises through a secondary magnetic field coil current magnetic field generated by the compensation, the compensation current of Is accurately reflect the current of primary side Ip, so that the Holzer device is in the working state of zero magnetic flux detection.

Q: Automatic tripping of circuit breaker often, this is why, what to do?: Generally speaking, there are two main causes of circuit breaker tripping. The first is short circuit. Similar conditions occur in a humid environment. Remember a customer reflects a DW16-2500 universal circuit breaker, sunny normal, rainy days often trip, that is caused by short-circuit. The final check is due to the short circuit of the control circuit, resulting in two line burn, resulting in tripping.

Q: Vc3266l digital caliper table phase sequence measurement: DC voltage measurement(1) select the function switch according to the required test 2 0V / 600V files. If you don't know the measured value, please select 600V for measurement.(2) the black pen plug ACOM jack, the red pen inserted V / Jack.(3) the test pen is connected to the power supply or load test.(4) the LCD display values of the measured voltage value, the red pen is connected with one end.(5) if LCD display "1" is connected with one end of the red pen is negative,

Q: Clamp ammeters on what hold is: The measured current is dynamic, so the digital clamp meter has been beating, press hold, can make the digital positioning in the moment of the current value of the press.
