The static measurement method mainly uses the multimeter to measure the on-line resistance of the components and the PN junction voltage on the transistors. The transistor tester is used to check the quality of the integrated circuit blocks and other components.
For example, an X-axis AC servo unit of a machining center is turned off after power is turned on. The maintenance personnel connected the X-axis control voltage line to the other axis servo unit to supply the control voltage. The other regulators were normal and a fault occurred. This indicates that the power supply has no failure. The cover shaft servo unit was removed for measurement. The DC voltage was +15 V. The machining center had a short circuit in the man-machine shaft servo unit. The resistance between +15 V and ov was. The machining center continued to check and found that there was a -47 p between +15V and ov. The F and 50V capacitors were broken. After replacing the capacitor, the +15V was no longer short-circuited and the servo unit returned to normal.
(7) Dynamic measurement method The dynamic measurement method uses visual inspection and static measurement to add the necessary AC/DC voltage, synchronous voltage and input signal to the printed circuit board according to the circuit schematic, and then uses a multimeter, a transmitter, etc. Fully diagnose and troubleshoot the printed circuit board's output voltage, current, and waveform. The dynamic measurement of the machining center includes voltage counting, current measurement, signal injection, and waveform observation.
The voltage measurement method is a universal measurement of the voltages of the suspicious circuit. Based on the comparison between the measured value and a known value or an empirical value, the machining center then applies logical reasoning to determine the fault.
The machining center current measurement method is a conventional method of checking an electronic printed circuit board by measuring the operating current of a transistor, an integrated circuit, a current of each unit circuit, and a power board load current.
The signal injection and waveform observation method is to use the signal generator or DC power supply input signal in the circuit to be investigated, and observe the output waveform with an oscilloscope.
Power equipment Wire Harness is widely used in life and can be seen almost everywhere. Power equipment mainly includes two categories: power generation equipment and power supply equipment. Power generation equipment is mainly power station boilers, steam turbines, gas turbines, hydraulic turbines, generators, transformers, etc. device and so on.
With the wide application of computers in economic development, some important places, such as finance, information, communication, industrial control systems, etc., have higher and higher requirements for the reliability and stability of power supplies, especially industrial control systems, which require high quality, high Stable power supply. When the power grid system suddenly loses power, the power supply must maintain power supply for a certain period of time, so as to protect the data of the industrial control system and keep the field instruments and regulating valves in a safe position. In the event of an accident, the UPS series industrial control wiring harness is very important. The connecting wiring harness is mainly used in electronic and electrical equipment. Most industries need to use connecting wire harnesses. The largest market segment is telecommunications, followed by industrial automation equipment such as automobiles and instruments, and the third largest market is medical, aviation, railway, transportation, etc.; such wire harnesses are mainly used in AC uninterruptible power supply systems, such as UPS and power distribution.
