Why should analytical instruments be equipped with a regulated power supply?
With the rapid development of industry in our country, various electronic appliances are widely used in various industries. During the use of electronic appliances, a large number of harmonics are generated, which inevitably cause interference and pollution to the power grid after returning to the power grid. These electronic appliances, such as computers, monitoring systems, small communication equipment, automation equipment, and some UPS power supplies, will generate harmonic interference. In addition, all analytical instruments that use high voltage for metallographic analysis use double voltage rectification. The high voltage is generated by a double voltage rectification type load, and its input current is a distorted bell shaped pulse wave with an opening angle of about 60 °. The input power factor PF ≈ 0.65, but the amplitude of the input current is very high, generating a large number of 3rd, 5th... odd harmonics. If it returns to the power grid, it will form mutual interference between adjacent equipment, Especially causing serious interference to the normal operation of analytical instruments.
In order 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 harmonic interference and other power grid pollution as well as lightning strikes. There are not many voltage regulators that need to have the above comprehensive functions, and Iron Tower parameter voltage regulators are outstanding in this regard. They have been widely used in industries such as Thermoelectric, Liko, PE, Agilent, Shimadzu, Hori, JY from France, Beijing NAC, Hyperspectrum, and Spike from Germany Supporting power sources such as Toledo weighing instruments.
When designing the Iron Tower AC parameter voltage regulator, it is fully considered that it must have a wide voltage range, high voltage regulation accuracy, short response time, small output voltage waveform distortion, bidirectional anti-interference ability, automatic load short-circuit protection, isolation, filtering and shaping, and must be able to withstand twice the power supply voltage impact without overvoltage output and other special functions, The Iron Tower AC Parameter Stabilizer is a narrowband filter with a frequency selection of 50HZ. It is designed to eliminate peak interference, harmonic interference, high-frequency interference, and lightning interference on the power grid, which cannot enter the equipment. The harmonics generated by the analysis instrument will not return to the power grid and will not interfere with each other.
In terms of lightning resistance, products with a capacity of 15KVA or above can achieve * * lightning protection (6000V) in terms of lightning resistance. Through the lightning stroke of the iron tower AC parameter regulator, a large lightning current of 40KVA can be discharged into the ground, achieving the purpose of current and voltage limiting, thereby protecting electrical equipment. In terms of lightning protection applications, the usage environment for radio, television, and mobile communication is relatively harsh. Many of these usage scenarios are on mountaintops and rooftops, and the risk of lightning attacks is very high. The Iron Tower AC parameter voltage regulator has been serving these industries for many years. Sometimes, after being struck by strong lightning, the input line package of the voltage regulator is blown up by lightning, but the electrical equipment behind it will not be damaged.
In addition, the three column core voltage regulator transformer of the Iron Tower AC parameter regulator has complementary magnetic flux, so the three-phase line voltage and phase voltage are relatively balanced. When there is 10% imbalance in the input three-phase or 10% imbalance in the load, the total output three-phase is still relatively balanced, with imbalance ≤ 3%. The AC parameter voltage regulator of the iron tower has been properly debugged, and its input end can serve as reactive power compensation for the power transmission line, while its output end can serve as
