Embodiment Construction

[0025] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0026] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "inner", "outer", "left", "right" and similar expressions are used herein for the purpose of descripti...

Abstract

The invention relates to a measurement and control system for pumping through of a generator rotor. The generator rotor pull-through measurement and control system includes a distance measuring probe, an inclination sensor, a control module and a display screen. The distance measuring probe is used to measure the gap between the rotor and the stator. There are multiple distance measuring probes, some distance measuring probes are arranged at intervals on the side wall of the rotor and are close to the first end, and some distance measuring probes are arranged at intervals on the inner wall of the stator and are close to the excitation end. The control module is connected with the distance measuring probe and can receive the first information sent by the distance measuring probe. The first information is the gap between the rotor and the stator. The staff can get the first information in time through the display screen, and can accurately adjust the position of the rotor relative to the stator to prevent the rotor from colliding with the stator. Compared with observation by human eyes, the data measured by the distance measuring probe is more accurate, which can improve the safety of pumping through the rotor. The inclination sensor is installed in the skateboard to measure the levelness of the skateboard, so as to ensure that the skateboard can bear load well and improve the safety of the project.

Description

technical field [0001] The invention relates to the technical field of generators, in particular to a generator rotor draw-through measurement and control system. Background technique [0002] Large-scale horizontal generators are often used in nuclear power projects, and the staff need to regularly pump through the rotor to check the use of the rotor. When pumping through the rotor, two lifting ropes are used to lift both ends of the rotor respectively, and then a slide plate for carrying the rotor is placed inside the stator. Usually, during the process of hoisting the rotor with a sling, multiple workers are assigned to the steam end and excitation end of the generator to monitor the gap between the rotor and the stator, so as to avoid damage to the generator due to the collision between the rotor and the stator. The rotor of this large horizontal generator is more than ten meters long. During the process of pumping through the rotor, the minimum gap between the rotor an...
