Changshu buys back power control cabinets, Ruian recycles box-type power transformers
Recycling Introduction: We have been recycling a wide range of transformers including dry-type transformers, box transformers, oil-immersed transformers, rectifier transformers, power transformers, electric furnace transformers, and modular transformers. The brands we recycle include Siemens, EKEA, Yijia, Xinying, Jingsai, Langteng, LNBRT, Leisu, Xingwedun, Anbian, Quan Tai, Huapeng, Huayu, Yike, and Zhaotai, covering both domestic and imported transformers. We also recycle distribution cabinets, low-voltage switchgear, ring main cabinets, power cabinets, electrical control cabinets, high-voltage switchgear, power distribution cabinets, complete low-voltage high-current distribution cabinets, positive pressure explosion-proof distribution cabinets, and lightning protection AC distribution cabinets.
If the silk is in good condition, there will be no output of DC voltages at various levels under load. This situation is mainly caused by the following reasons: open circuit or short circuit in the power supply, failure in overvoltage and overcurrent protection circuits, auxiliary power supply failure, oscillation circuit not functioning, excessive power supply load, rectifier diodes in the high-frequency rectification and filtering circuit being punctured, and leakage in the filtering capacitors. After measuring the secondary components with a multimeter and excluding the possibility of punctured high-frequency rectification diodes and short-circuited loads, if the output is still zero at this point.
【Product Application】This product is suitable for three-phase AC 50Hz, 40.5kV single busbar segmented power systems, used in power plants, sub-stations, industrial and mining enterprises, and high-rise buildings for receiving and distributing electrical energy. It also implements control, protection, and monitoring of the circuit, meets the requirements of IEC60298, DL404, and other standards, and has a complete "Five Preventive" function. 【Usage Conditions】1. Surrounding air temperature: Maximum of 40°C, minimum of -10°C; 2. Altitude: Not exceeding 1000m; 3. Relative humidity: Daily average not greater than 95%, monthly average not greater than 90%; Saturated vapor pressure: Daily average not exceeding 2.2×10 Mpa, monthly average not greater than 1.8×10 Mpa; 4. Seismic intensity not exceeding 8 degrees; 5. Surrounding air should not be significantly polluted by corrosive gases, flammable gases, steam, etc.; 6. No frequent violent vibrations. If the switchgear usage conditions exceed the above specifications, the user and the manufacturer shall negotiate and determine.
