Hammering device, system and method for dynamic characteristic analysis of stator winding end of large condenser

Abstract

A hammering device, system and method for analyzing the dynamic characteristics of the stator winding end of a large-scale condenser, the hammering device is characterized in that it includes a test hammer, and a fixed card seat is arranged on the test hammer, and the opposite sides of the fixed card seat are respectively installed with Movable tab; the test hammer moves in a track formed by two oppositely arranged arc bars, and electromagnets are respectively embedded in the relative positions of the inner surfaces of the two arc bars, and the electromagnets and the inner surfaces of the arc tracks are in the In the same plane; when the detection and control circuit detects the drop of the test hammer, the control electromagnet is energized, and the movable tabs on both sides of the fixed deck when the test hammer rebounds and goes up are attracted, and the test hammer is fixed. The hammering device of the present disclosure utilizes a detection and control circuit to realize that the test hammer is bounced up and then fixed after a hammering test once, avoiding secondary falling, and ensuring measurement accuracy.

Description

technical field [0001] The disclosure relates to the technical field of testing, in particular to a hammering device, system and method for analyzing the dynamic characteristics of the end of a stator winding of a large-scale condenser. Background technique [0002] In order to assess whether the dynamic characteristics of the stator winding end of the large-scale condenser engineering unit meet the standard requirements, it is necessary to test the dynamic characteristics of the stator winding end of a single unit. [0003] For the test of the dynamic characteristic analysis of the stator winding end of the large condenser, in this test, the traditional test method uses artificial hammering to generate the excitation signal. However, the strength of artificial hammering excitation is not fixed, and the working effect varies from person to person. People are prone to fatigue after a long test time, which affects the test efficiency. Contents of the invention [0004] The ...
