In order to convert AC power to DC power, the rectifier transformer first converts the voltage of the AC power grid into a voltage of a certain size and number of phases, and then passes through a rectifier (rectifier) and outputs it to the DC drag device. Three-phase dry-type rectifier transformer ---- Applicable occasions: Rectifier transformer is a power transformer for rectifier equipment. Its task is to convert AC to a certain size and number of phases, and then rectify through rectifier components to meet the DC output. Requirements. In addition, the rectifier transformer also has the following functions: to isolate the rectifier equipment from the circuit of the power grid, ensure the safety of equipment and people, limit the short-circuit current, reduce the electromagnetic interference between the rectifier equipment on the power grid or other parallel-operated rectifier equipment, and suppress the Current rise rate of rectifiers such as thyristors. It is produced by our company using high-quality materials and advanced technology for many years. It has the advantages of moisture resistance and easy maintenance. It can penetrate into load centers and three-phase rectifier transformers. It is mainly used for AC 50-60Hz, and is widely used in electrolysis (electrolysis). , Frequency conversion, traction, DC power transmission, electroplating, spraying, electrical processing, charging, excitation, transmission, experimental equipment, lighting, machine tool appliances, medical equipment, mechanical and electronic equipment, rectifiers and electrostatic precipitators, and general industrial rectifier power supplies and other industries, Product performance can meet various special requirements of users. Three-phase dry-type rectifier transformer ---- Performance characteristics: Stable gas performance: The product combines load characteristics with grid voltage fluctuations and atmospheric over-voltage conditions, and determines a reasonable and reliable insulation level and insulation model according to the load condition of the rectifier transformer to ensure forfeiture The electrical performance of the product is reliable and stable. Product environmental safety factor ≥ 1.67. High dynamic stability: The winding of the product has high mechanical strength and strong anti-burst ability to meet the extremely harsh load environment. During the design and manufacturing process, the sources of dynamic instability caused by magnetic leakage of the transformer or abnormal transportation may be eliminated. The product has high dynamic stability. High impedance, 30% higher impedance than power transformers of the same capacity to suppress di / dt and effectively protect rectifier components. Good thermal stability: Advanced product design, strict control of the product's heating parts and * hot spot temperature rise, coils, leads using copper wire, low current density selection. Strong overload capacity: The product has strong overload capacity and over-voltage capability. The product design and manufacturing fully consider the load characteristics, and meet the overload requirements from various aspects such as temperature rise, insulation performance and accessories selection. The power saving effect is obvious, and the noise is low (<65dB). Simplified structure and beautiful appearance. Three-phase dry-type rectifier transformer ---- Use environment: ambient air temperature and altitude: the upper limit of ambient air temperature does not exceed + 40 ° C, the average value of ambient air temperature for 24h does not exceed + 30 ° C, and the lower limit of ambient air temperature is not lower than 5 ℃, the altitude of the installation site does not exceed 1000 meters, and the installation is in a place without severe vibration and shock vibration. Pollution level of atmospheric conditions: The relative humidity of the atmosphere does not exceed 50% when the ambient air temperature is + 40 ° C, and it can have a higher relative humidity at a lower temperature. * Wet monthly average ** Relative humidity is 90%, and the month The average temperature is + 25 ° C, and the condensation on the product surface is taken into account due to temperature changes; the pollution level is three; the power supply voltage: the allowable deviation of the power supply voltage is ± 5%; the installation site has no gas or steam that seriously affects the transformer insulation , Chemical deposits, dust, dirt and other explosive and corrosive media. For special use conditions that do not meet the above requirements, the user and the factory should discuss the matters needing attention: 1) Before purchasing, estimate the total capacity of the electrical appliances you use, and choose a transformer with the corresponding capacity to ensure that The transformer will be burned out; 2) Before installation, carefully check whether the parameters marked on the nameplate meet your requirements, and install it after confirming that it is correct; 3) After power-on, the transformer core and coil will heat up (but the temperature rise does not exceed 80 ℃) ) It is a normal phenomenon. If the temperature rise exceeds 80 ° C or smoke is generated, the power should be cut off and the capacity of the electrical appliances used should be rechecked. 4) During use, please pay attention to maintenance to protect the life of the transformer. 5) During transportation, it should be as far as possible Avoid collisions and do not get wet.
