Realize the "no dead ends" of circuit inspections to better ensure the safe and stable operation of the power grid

The line inspection “no dead ends” provided better protection for the safe and stable operation of the power grid. On the morning of March 14th, an electric four-rotor drone was slowly lifted along the salt lake in Chaka, Wulan County, Haixi, Qinghai. The Qinghai-Tibet network 750 kV seawood I line inspections. This is the first time that Qinghai Power Grid has used UAV technology to inspect 750 kV lines.

At present, Qinghai Electric Power Inspection and Repairing Company has configured two quad-rotor unmanned aerial vehicles and organized the trial application of daily inspection and failure inspection techniques for drones, and clarified the organization and work of drone inspection management organizations. Processes, preparation of relevant management procedures and standards. In the next step, the company will actively promote the normalization of drone inspection work, further improve the video interface display and information access of drones, further improve the research of auxiliary operations, and complete the training, maintenance, guarantee, and emergency management system. The construction of the drone makes it better applied to the transmission line inspection work.

The UAV inspection line for the Qinghai-Tibet network 750 kV Hichai I, II line 125 to 138, a total of 14 base tower, the total length of 9.118 kilometers, the flight altitude of 280 meters, a total of four flights. Ground personnel control drones have completed two work of high-definition inspection and infrared temperature measurement, and constantly change the shooting angle and distance, hover photos of the hanging part of the wire. In-flight inspections were conducted on wires, spacers, and line channels to realize real-time image transmission and rapid splicing. This effectively assisted the staff in patrolling the mountainous lines and realized the line inspection “no dead ends”. To ensure a safe and stable operation of the power grid.

Boiler Air Preheaters

Air preheater is one of the most important accessories in modern boilers. Air preheater is commonly found in all modern boilers. To increase the efficiency of the boiler accessories like air preheater is used in the boilers.

Types of air preheater in a boiler

The air preheaters are classified into two types based on their features and construction. These two types of air preheater are

Recuperative or Tubular type air preheater

Regenerative or Rotational type air preheater

Recuperative or Tubular type air preheater is further classified into two types, they are

Horizontal tubular type

Vertical tubular type

Regenerative or Rotational type air preheater is also classified into two types they are

Rotating baskets (Ljungstrom)

Rotating hood (Rothemuhle)
