Civil Aviation Resource Network May 30, 2019 News: On May 22nd, at the Xiantao Airport in Hubei, the Bell 429 external load operation unit of the State Grid Corporation was carrying out training on helicopter manned live working based on UHV lines.
The helicopter live working technology is a method of using the helicopter to transport the maintenance personnel to the fault location of the transmission line directly or through an indirect way such as a sling to complete the line maintenance task. It is mainly divided into two major types of operation methods: platform method and suspension method. Among them, the suspension method can be subdivided into two processes: the sling method and the hanging basket method. At present, the company is carrying out helicopter manned sling method and hanging basket method for live working, which is to use helicopters to put maintenance personnel and tool materials on the power line for live operation. After the work is completed, the helicopter and personnel will be used. And the way in which the tool materials are withdrawn.
The company invited the New Zealand professional training company's instructors to use the Bell429 dual-hair helicopter to carry out training, the main content includes basic ability training, sling method flight training and hanging basket method flight training. The flight crew is required to be precise and proficient in the flight operation process of the sling method and the hanging basket method. It can cooperate with the on-line electrified maintenance personnel to safely and quickly send the maintenance personnel to the suspended guide and ground to carry out the equipotential. Operation; the trainee electrified maintenance personnel system masters the connection mode of the hanging system, and is skilled in the installation and connection of the hanging system with the personnel and the hanging basket, mastering the technical essentials of the flight process, and being able to safely and smoothly enter and exit under the guidance of the helicopter. With conductance, ground operation procedures, etc.
Through continuous training and capacity improvement, State Grid Navigation Corporation will speed up the establishment of electrified maintenance operations based on helicopter D-type external load mode, actively implement the strategic deployment of “three-type, two-network, world-class” of State Grid Corporation, and further develop the advanced operation of helicopter operations. Sexuality and high efficiency, greatly improve the efficiency and safety margin of power grid construction, and effectively guarantee the safe and stable operation of the State Grid Corporation's large power grid. Leading technology companies such as people are exhibiting.
