Jiangyin purchases high-voltage distribution cabinets and recycles dense busbars

Recycling Overview: I have been long-term in the recycling of dry-type transformers, box transformers, oil-immersed transformers, rectifier transformers, power transformers, electric furnace transformers, and modular transformers, among others. The brands include Siemens, EKEA, Yijia, Xinying, Jingsai, Longtening, LNBRT, Leisu, Xingwodun, Anbian, Quanta, Huapeng, Huayu, Yike, and Zhetai, covering both domestic and imported transformers. We also recycle distribution cabinets, low-voltage switchgear, ring main units, power cabinets, electrical control cabinets, high-voltage switchgear, power distribution cabinets, complete low-voltage high-current distribution cabinets, positive pressure-type explosion-proof distribution cabinets, and lightning protection AC distribution cabinets.

Braking and Parking Circuit: The control section that cuts off the power supply to the circuit, and implements certain braking measures to quickly stop the motor, including energy consumption braking, reverse power supply braking, reverse traction braking, and regenerative braking, etc.; 6. Self-Locking and Interlock Circuit: The electrical section that maintains power supply to the circuit after the start button is released, allowing the electrical equipment to continue operating is called the self-locking section, such as the auxiliary contact of a contactor in series with the coil circuit. The protection section that ensures only one of two or more electrical devices or components can be powered on at a time for safety and reliability is called the interlock section. For example, the auxiliary contacts of two contactors are respectively connected in series with the coil circuit of the other.

Circuit Breaker Failure Prevention Measures: If the operation personnel find that the indicator lights for opening and closing the circuit breaker are not illuminated, they should promptly check if the opening and closing circuit is disconnected. During maintenance, the maintenance personnel should pay attention to measuring the resistance of the opening circuit breaker coil and inspect if the top rod of the opening circuit breaker is deformed. If the material of the top rod is copper, it should be replaced with steel. It is necessary to carry out low-voltage opening and closing tests to ensure the reliability of the circuit breaker performance. [Circuit Breaker] Spring-operated mechanism failure of the closing energy storage circuit: (1) After closing, the opening operation cannot be achieved; (2) The energy storage motor does not stop running, which may lead to overheating and damage of the motor coil.
