Analysis of analytical instruments why should be equipped with a regulated power supply?
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 rectified load, the input current is a very 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 neighboring equipment, especially for the normal operation of analytical instruments to bring serious interference.
To provide power for analytical instruments, in addition to a higher accuracy of voltage stabilization and a larger range of voltage stabilization, that is, to fight against harmonic interference and other grid pollution and lightning strike, to have the above comprehensive functions of the voltage regulator is not much, and the iron tower brand parameter regulator is the best in this regard, which has been used in a large number of applications, such as: U.S. Thermo-electricity, force can be, PE, Agilent, Japan Shimadzu, Hori taste of France JY, Beijing, Nak, Super Spectrum, Germany Spike, Toledo scales and other supporting power supply.
AC parameter voltage stabilizer in the design, it will be fully considered must have a wide range of voltage stabilization, voltage stabilization precision should 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, Tieta AC parameter voltage stabilizer, it is a selective frequency of 50Hz, narrow-band filter, the frequency of 50 HZ, the frequency of 50 Hz, the frequency of 50 Hz is selected. It is a narrow-band filter for the power grid spike interference, harmonic interference, high frequency interference, lightning interference can not pass through it and enter the equipment, analyzing the harmonics generated by the instrument will not return to the power grid, and will not interfere with each other.
AC parameter regulator in the anti-lightning, 15KVA or more products in the lightning protection ability to reach ** lightning (6000V), through the AC parameter regulator of lightning, can be a large lightning current 40KVA leakage into the ground to achieve the purpose of limiting the current and voltage limit, so as to protect the power equipment. In the application of lightning protection, when it comes to radio, television, mobile communications, the use of harsh environments, the use of 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 iron tower brand AC parameter regulator for many years on the service in these industries, sometimes, after a strong lightning strike, lightning regulator input line package blowing up, but it will not be damaged behind the power equipment.
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%. Tieta AC parameter regulator after appropriate debugging, 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.
