Description

QLFM Isolated phase enclosed bus duct is a kind of high-current transmission device which is extensively applied in generator main lead-out wire loop and power station Service/auxiliary Transformers. Product Type Enclosed busduct Design Criteria GB/T 8349 Conductor Type Al pipe Frequency 50/60 Hz Rated Voltage 10KV--40.5KV IP IP54 Product Series Isolated phase busduct The Isolated phase enclosed busway is a large-current transmission device widely used in 50MW and above generator lead-out circuits and factory branch circuits. The system can be effectively prevented from the grounding fault caused by moisture, dust and external factors under the protection of enclosure. Short-circuit will be avoided between phases because of isolated phase enclosed structure. The conductors inside are all connected with flexible braided straps to eliminate the vibration of connected equipment. Current transformer can be set up according to the requirement for the purpose of measurement and protection. Through the hydrogen measurement, temperature measurement, and humidity measurement devices, the online temperature, humidity, and hydrogen leakage of the busbar body, the outer casing, and the internal environment of the busbar are intelligently displayed. By controlling the micro-positive pressure equipment, the hot air maintenance device can prevent external dust and moisture from entering the busbar, effectively improve the safety index of the whole set of busbars, and ensure the safety and reliability of the busbar system.
