Analysing analytical instruments Why should a regulated power supply be used?
With the rapid development of China's industry, all walks of life are a large number of electronic appliances, and electronic appliances in the use of the process will produce a large number of harmonics, return to the grid after the inevitable grid interference, the formation of grid pollution, such electronic appliances such as computers, monitoring systems, small-scale communications equipment, automation equipment and some UPS power supply will produce harmonic interference. In addition, where the use of high-voltage metallurgical analysis of analytical instruments, the generation of high-voltage are used to multiply the rectifier, doubling the rectifier type load, the input current is a large distortion of the stalactitic pulse wave, the opening angle of about 60 °, the input power factor of PF ≈ 0.65, but the amplitude of the input current is very high, resulting in a large number of 3rd, 5th ... ...Odd harmonics, if returned to the power grid will form the mutual interference of the adjacent equipment, especially for the normal work of the analytical instruments to bring serious interference.
AC parameter voltage regulator in the design, it is fully considered must have a wide range of voltage regulator, voltage regulator precision to be high, the response time should be short, the output voltage waveform distortion should be small, must have a two-way anti-interference ability and load short-circuit auto-protection, isolation, filtering and shaping, must be able to withstand the double power supply voltage shock will not appear over-voltage output, and other special features, Titan AC parameter regulator, it is a selective frequency of 50Hz, narrow-band filter, and the frequency of 50 HZ, the frequency of 50 Hz, the frequency of 50 HZ, the frequency of 50 Hz, the frequency of 50 Hz, the frequency of 50 Hz. It is a narrow-band filter for the spike interference, harmonic interference, high-frequency interference, lightning interference on the power grid can not pass through it and enter the equipment, the harmonics generated by the analysing instruments will not return to the power grid, and there will be no interference between each other.
AC parameter regulator in the anti-lightning strike, 15KVA or more products in the lightning protection ability to lightning (6000V), through the AC parameter regulator lightning strike, can be a large lightning current 40KVA drain into the ground to achieve the purpose of limiting the current and voltage, thus protecting the power equipment. In the application of lightning protection, belonging to the radio, television, mobile communications using the environment is more severe, many of these occasions are on top of the mountain, the roof of the building, they are subjected to lightning attack risk is very large. And AC parameter regulator for many years on the service in these industries, sometimes, after a strong lightning strike, lightning regulator input line packet blowing up, but it is behind the power equipment will not be damaged.
In addition, AC parameter voltage regulator three column core voltage regulator transformer its three columns of magnetic flux is complementary, so the three-phase line voltage and phase voltage is more balanced, when the input three-phase 10% imbalance or load 10% imbalance, a total of three-phase output is still relatively balanced, unbalance ≤ 3%. Tower AC parameter voltage regulator after appropriate commissioning, its input can be used as power transmission line reactive power compensation, its output can be used as equipment capacitive reactive power compensation, its power factor ≥ 0.95.
Therefore, over the years, the voltage regulator is widely used in a variety of high-risk power protection sector, such as banks, government agencies important power units, hospitals, national defence, aerospace and so on.
