Description

Technical Field

[0001] The present invention relates to the technical field of hoisting and replacing large dry-type reactors in ultra-high voltage substations, and more specifically to a device and method for hoisting large dry-type reactors close to the power grid. Background Art

[0002] The primary equipment in the ultra-high voltage (500 kV and above) substation has high requirements for insulation level. The design size of large dry-type reactors is usually large. When the equipment needs to be hoisted and replaced due to aging or failure, a large crane is required to cooperate with the operation. To ensure the safety of operators and equipment, the crane body, boom, and hoisted equipment should strictly maintain a safe distance of the corresponding voltage level from the adjacent live equipment when hoisting the dry-type reactor.

[0003] At present, when hoisting large dry-type reactors, in order to ensure a safe distance from nearby live equipment, it is necessary to shut down the adjacent equipment or nearby cross-lines. This hoisting condition is affected by the overall power grid operation mode and reactive load distribution. The adjacent equipment or nearby cross-lines cannot be shut down in time, which seriously affects the hoisting of aging and faulty dry-type reactors. In addition, due to the complex structure of dry-type reactors and the numerous overall replacement procedures, the use of traditional cranes or new folding arm cranes cannot solve the problem of hoisting large dry-type reactors near live equipment under different operating environments.

[0004] There are few relevant technical patents for the close-to-electric lifting of large dry-type reactors in ultra-high voltage substations. The existing document CN117800209A (Large-scale reactor lifting equipment in ultra-high voltage 1100kV GIS AC withstand voltage test) proposes a reactor lifting device with multiple lifting locks and telescopic rods for the lifting of reactors in the AC withstand voltage test of ultra-high voltage substations; the document CN115783990A (A dry-type reactor lifting device) provides a lifting device suitable for the lifting of small dry-type reactors; the document CN216971694U (New large-size reactor lifting device) provides a device for lifting large dry-type reactors.

[0005] The above technical patents can only be used for lifting live equipment near the reactor or during cross-line power outages. They are not suitable for lifting near power lines. In addition, many devices and equipment are required to complete the lifting, which is not easy to operate and does not meet the requirements for lifting near power lines.

[0006] Therefore, how to provide a special device and method for near-power hoisting of large dry-type reactors that can adapt to a wide range of scenarios, is easy to operate, portable, and meets the needs of near-power hoisting is an issue that technical personnel in this field urgently need to solve.
