Taixing recycles second-hand rectifier cabinets and dense busbars

Recycling Introduction: I have been recycling a wide range of transformers including dry-type, box-type, oil-immersed, rectifier, power, electric furnace, and combination transformers, as well as brands like Siemens, EKEA, Yijia, Xin Ying, Jingsai, Langteng, LNBRT, Leisu, Xingwodun, Anbian, Daban, Huapeng, Huayu, Yike, and Zhetai, covering both domestic and imported transformers. We also handle the recycling of distribution panels, low-voltage switchgear, ring main units, power cabinets, electrical control cabinets, high-voltage switchgear, power distribution panels, complete low-voltage high-current distribution panels, positive-pressure explosion-proof distribution cabinets, and lightning protection AC distribution cabinets.

The operation of a switching power supply is quite easy to understand. Unlike linear power supplies, where power transistors operate in linear mode, PWM switching power supplies keep the power transistors in a state of conduction and cutoff. In these two states, the voltage-amperage product applied to the power transistors is very small (low voltage, high current during conduction; high voltage, low current during cutoff). The voltage-amperage product on the power devices is the loss generated by power semiconductor devices. The more efficient operation process of PWM switching power supplies compared to linear power supplies is achieved through "chopping," which involves converting the input DC voltage into a pulse voltage with an amplitude equal to the input voltage amplitude. The duty cycle of the pulse is adjusted by the controller of the switching power supply. Once the input voltage is chopped into an AC square wave, its amplitude can be increased or decreased by a transformer. By increasing the number of secondary winding turns of the transformer, the output voltage can be increased. These AC waveforms are then rectified and filtered to produce a DC output voltage.

Adjust the peak electricity load reasonably. Under normal circumstances, the transformer's load rate should be kept around 60% to minimize losses. Therefore, during peak electricity consumption periods, optimize the operation plan by removing some relatively unimportant mechanical and electrical loads and lighting loads to reduce peak loads. For public lighting and office equipment management, try to dim the light or promptly turn off the lights without special need, and avoid keeping decorative lighting on for extended periods. For areas with low personnel movement, use sensor, voice-activated, and touch-switch closures for lighting control. If possible, implement real-time control of the public lighting system. For office equipment like computers that are not used for a long time, promptly disconnect the power supply to reduce standby losses.
