Light equipment efficiency and service life to reduce the weight to cause breakdown damage
Focuses on the harmonic origins, laws, and the impact and danger of the device on the network (system), and filter set principles and laser cutting machine the IGBT shooting for (with) the quality of electric power warning. Our company introduced the Italian the PRIMA company PLATINO1530-2.2-type laser cutting machine, a critical juncture in the processing and production, "blasting the IGBT fault for some reason on November 15, 2002 in the high voltage power supply box, directly affecting the normal production. Italian PRIMA agent maintenance experts and PRC Chinese agent maintenance expert panel, they think only three causes of "blasting": "ignition coil" cooling-off bad (lack of water or inadequate water supply); for (distributed) power quality have a problem; operational errors. Our company laser cutting machine high voltage power supply box "IGBT blasting" is one of the best description. It is the current market of wireless presenter laser pointer pen .
Frequent fluctuations in supply voltage, the operation of other equipment connected to the same network, especially for electronic devices, is extremely unfavorable. Synchronous motor, a sharp voltage fluctuations may generate oscillations; the general equipment, low voltage, make AC contactor, relay coil smoke is not so high that the coil quickly overheat damage. Voltage is too low or too high for electronic device (system) can make the electronic components caused by overheating of signal alarm and damage. Grid frequency instability, more than the specified range, will also affect the normal working of the electronics and electrical instrumentation, which can affect the phase of the trigger pulse inaccurate, resulting in the SCR device inverter subversive. The radio frequency wireless presenter 200mw laser pointer is more popular and widely used. green laser pointer contains the radio frequency wireless presenter 200mw laser pointer .
Repeated discussions with experts, research, recognized as for (distributed) power quality is caused by the high voltage power supply box of the laser cutting machine in the IGBT blasting "the main reason. As the so-called: the introduction of foreign technology, only the introduction of "tangible" technology - in-kind equipment, but not the introduction of "intangible" technology - technology theory, detailed in the equipment design and manufacturing experience. And where the introduction of foreign equipment carried by most of the technical information is limited, only the commercial introduction, there is no maintenance, "Jiaodi. What is more, where (ministry) can carry out maintenance on its own "demolition". How the intangible wonders of technology "bluntly, the system master, need to learn to improve our good. These two kinds of wireless presenters green laser pointer have their own characteristics and advantages.
The basic concept and scope of power quality and power supply interference ": the so-called power quality is to look at the AC power supply voltage, frequency and waveform (known as the three main factors of the power quality). Changes in a certain period with the provisions of the Statutes and equipment requirements for the degree of difference between the values, and power supply interference fall into this category. Any of these factors on the reliability of the electronic device (system) has a direct impact caused by electronic devices (system) work is unreliable, unstable or alarm, when these (V, HZ, waveform) exceeds or is lower than the limits .
