Abstract

The invention relates to a tester for a variable flow controller of a wind power generating set and a detection method thereof. The control board and the control button installation board connected with the central control board, the central control board includes a power generation circuit, an analog signal detection circuit and a digital signal detection circuit, and the digital signal detection circuit includes a plurality of IGBT units. The method comprises the following steps: connecting the converter controller and the tester; closing the power switch of the converter controller and the tester, turning on the switch of the module to be detected by the tester; turning on the power switch of the tester and the power switch of the converter controller in turn; Determine whether the detected module is faulty according to the indicator light. The tester can conduct a comprehensive test on the converter controller, is easy to maintain, and can set the signal, which solves the problem of using a signal generator to connect in the past.

Description

technical field [0001] The invention relates to the field of testing of wind power generating equipment, in particular to a tester for a converter controller of a wind power generating set and a detection method thereof. Background technique [0002] The rapid development of the wind power industry has also brought about a serious consumption of spare parts. In order to ensure that wind power manufacturers have lower operating costs, spare parts maintenance manufacturers have sprung up everywhere, and the maintenance technology is also uneven. The industrial control equipment in the wind power industry has the characteristics of difficult maintenance and complex faults, which cause great difficulties for maintenance. The maintenance of existing industrial control devices can only rely on traditional instruments and meters: oscilloscopes, multimeters, function signal generators and logic analyzers, etc. The input and output of signals can only be led out by cables when testin...
