Why Analytical Instruments Should Be Equipped with Stabilized Power Supply

 

With the rapid development of my country's industry, a large number of electronic appliances are used in all walks of life, and electronic appliances will generate a large number of harmonics during use, which will inevitably bring interference to the grid after returning to the grid and form grid pollution. Class electronic appliances such as computers, monitoring systems, small communication equipment, automation equipment and some UPS power sources will generate harmonic interference. In addition, for all analytical instruments that use high voltage for metallographic analysis, the high voltage is generated by voltage doubler rectification, voltage doubler rectifier load, and its input current is a stalactite-shaped pulse wave with great distortion, and the opening angle is about 60° , the input power factor 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, it will cause mutual interference with adjacent equipment, especially for the normal operation of analytical instruments Work is seriously disrupted.


To provide power for analytical instruments, in addition to having high voltage regulation accuracy and a large voltage regulation range, it is necessary to resist grid pollution such as harmonic interference and anti-lightning strikes. There are not many voltage stabilizers with the above comprehensive functions. The iron tower brand parametric regulator is the best in this respect, it has been widely used in such as: Thermoelectric, Leco, PE, Agilent, Shimadzu Japan, JY Horichang France, Beijing Nanoco, Super Spectrum, Germany Schmidt Parker, Toledo weighing instruments and other supporting power supply.


When designing the AC parametric voltage stabilizer, it is fully considered that it must have a wide range of voltage regulation, high voltage regulation accuracy, short response time, small output voltage waveform distortion, bidirectional anti-interference ability and load short-circuit automatic protection, Special functions such as isolation, filter shaping, and must be able to withstand twice the power supply voltage impact without overvoltage output. The Iron Tower brand AC parameter voltage stabilizer is a narrow-band filter with a frequency selection of 50HZ. Wave interference, high-frequency interference, and lightning interference cannot enter the equipment through it, and the harmonics generated by the analysis instrument will not return to the power grid, and will not interfere with each other.

In terms of anti-lightning strikes, the products above 15KVA can achieve lightning protection (6000V) in terms of lightning protection capabilities. Through the lightning strikes of the Iron Tower brand AC parametric regulators, the large lightning current 40KVA can be discharged into the ground, reaching the limit. The purpose of current limiting and voltage, thus protecting the electrical equipment. In the application of lightning protection, the use environment of radio, television and mobile communication is relatively harsh. Many of these use occasions are on the top of mountains and buildings, and the risk of being attacked by lightning is very high. The Iron Tower brand AC parameter stabilizer has been serving these industries for many years. Sometimes, after being struck by strong lightning, the lightning will blow up the input wire package of the stabilizer, but the electrical equipment behind it will not be damaged.


In addition, the three-column core stabilized transformer of the AC parameter voltage stabilizer has three-column magnetic fluxes that are complementary, so the three-phase line voltage and phase voltage are relatively balanced. When the input three-phase is 10% unbalanced or the load is 10% unbalanced , A total of three-phase output is still relatively balanced, unbalanced ≤ 3%. After proper debugging, the AC parameter voltage stabilizer of the iron tower can be used as the reactive power compensation of the power transmission line at the input end, and the capacitive reactive power compensation at the output end of the equipment, and its power factor is ≥0.95.
