Apparatus and method of vibration testing for manufacturing defect detection in composite insulators |
摘要 |
The present application relates to an apparatus and method for detecting defects in composite insulators used in power systems. The apparatus includes a test frame, a hydraulic cylinder connected to a first end of the test frame for imparting a load on a composite insulator, a hammer for imparting excitations into the composite insulator, and a data collection device for collecting frequency responses traveling in the composite insulator as a result of the hammer striking the insulator. The composite insulator is secured between the hydraulic cylinder and a second end of the test frame. |

1. An apparatus for testing composite insulators, comprising:
(a) a test frame having spaced-apart first and second ends; (b) a hydraulic cylinder connected to the first end of the test frame; (c) a composite insulator connected to the hydraulic cylinder and the second end of the test frame, with the hydraulic cylinder and composite insulator are disposed in a parallel, in-line configuration to each other; (d) a hammer for imparting non-destructive excitations into the composite insulator; and (e) one or more accelerometers attached to the composite insulator for collecting frequency responses traveling in the composite insulator as a result of the hammer striking the insulator. |
