Generator set stator structure and stator measuring point arrangement method

Abstract

The embodiment of the invention provides a generator set stator structure and a stator measuring point arrangement method, relates to the technical field of hydro-generator operation on-line monitoring, and can detect whether iron core punching sheets in a stator iron core are mutually compressed or not in real time. The fastening assembly is used for keeping the stator core in a compressed state; and the force measuring assembly comprises a pressure sensor, and the pressure sensor is arranged between the stator core and the fastening assembly and is used for measuring a relative pressure value between the stator core and the fastening assembly. According to the generator set stator structure provided by the embodiment of the invention, the compression state of the stator core can be detected in real time, and a corresponding detection assembly does not need to be arranged on the core punching sheet, so that the influence on the stator core is avoided; as the detection device is arranged outside the stator core, the interference of the stator core is less, and the measurement resolution is high; the generator set stator structure provided by the embodiment of the invention adopts an assembly part nesting mode, and is high in integrity.

Description

technical field [0001] The application relates to the technical field of on-line monitoring of hydraulic generator operation, in particular to a stator structure of a generating set and a method for arranging stator measuring points. Background technique [0002] The stator core is formed by stacking multiple core punches. When the core punches are not compressed, the electromagnetic force and mechanical force when the hydro-generator unit is working will cause the core punches to shift in multiple directions. The core punches themselves It is easy to be damaged, and at the same time, the loose core punch may also cause contact friction against the through-core screw, which will damage the insulation layer on the through-core screw and cause a short circuit, resulting in burning accidents of the screw and the contacted core punch; even It is also possible to cut the insulation of the slot part of the stator bar, causing more serious accidents; therefore, it is necessary to o...
