Abstract

The invention discloses a generator rotor hoisting air gap monitoring and protection device, comprising: a protection device for the rotor's collision sensing feedback; a monitoring communication module for receiving and processing the feedback information of the protection device, and sending instructions to the reporting and warning module ;Report warning module, used to receive instructions from the monitoring communication module and issue an alarm; distance measurement module, used to measure the distance between the rotor and the bottom of the machine pit; feedback display module, receive and process the feedback information, and display the rotor through 3D graphic simulation The hoisting process and status; the power supply protection module is used to provide power. The protection device realizes protection and monitoring within the limited gap between the rotor and the stator. Through the cooperation of various modules, the labor required is greatly reduced, the equipment protection is simple, safe and effective, the hoisting monitoring covers the whole part without leaving hidden dangers, and the equipment squeezes and bumps the alarm in time, and the position is correct. The operation is intuitive and visible, the hoisting process is displayed synchronously, and the bottom of the hoisting part can be monitored to ensure the safety of personnel and equipment, making hoisting simple and fast.

Description

technical field [0001] The invention relates to the technical field of generator rotor hoisting, and more specifically, the invention relates to an air gap monitoring and protection device for generator rotor hoisting. Background technique [0002] At present, the generator rotors of vertical hydroelectric units in hydropower stations are mainly hoisted by wire rope balance hoisting. The weight of generator rotors of Yangtze Power (including the world’s largest) is between tens of tons and 2,300 tons, and the distance between the generator rotor and the stator The maximum air gap between them is only 42mm, so the difficulty of hoisting can be imagined. In order to ensure the safety of the hoisting process and not cause damage to the rotor and stator, the current protective measures are hoisting operations in the form of artificial continuous inserting plates around the circle and the whistle command and alarm method. This kind of hoisting operation method is labor-intensive...
