Description

Portable wind-driven generator fault information acquisition device

Technical field

This utility model relates to Wind turbines failure data acquisition, belongs to fault information acquisition technical field.

Background technology

Wind-power electricity generation is as a nascent technology, it is desirable to obtain stable and permanent development, it is necessary to constantly reduces and manufactures installation cost, and reduces unit day-to-day operation maintenance cost.But due to the particularity of Wind Power Utilization, under conditions of unit self is operated in very badly throughout the year, mostly it is arranged on the places such as high mountain, grassland and wilderness, and cabin is positioned at top mostly, and the fault diagnosis of wind-driven generator is brought inconvenience.

The topmost problem of current wind generator set monitoring system is how to reduce the burst accident of Wind turbines key position, how to reduce the maintenance cost of unit and improve generating efficiency, and these become following wind-powered electricity generation investment, build and safeguard the problem that must solve.The substantial amounts of fact and data show, light feasible wind-driven generator fault information acquisition device is for understanding the performance state of complex device, find incipient fault early, guarantee engineering has completed vital effect, can improve the operational management of equipment and reduce maintenance cost in terms of economic benefit.

Therefore, a kind of wind-driven generator fault information acquisition device is researched and developed most important to the operational reliability improving wind-powered electricity generation year unit.

Summary of the invention

The technical problems to be solved in the utility model is to provide a kind of Portable wind-driven generator fault information acquisition device.

This utility model is a kind of Portable wind-driven generator fault information acquisition device, and this system specifically includes that current transformer, voltage transformer, A/D sampling A/D chip, F28335DSP, LCD12864.No. 0 and No. 1 passage gathering selection A/D sampling A/D chip of fault message, current transformer is connected on AI0 and the AIGND pin of A/D sampling A/D chip, voltage transformer is connected on AI1 and the AIGND pin of A/D sampling A/D chip, A/D sampling A/D chip and F28335DSP connect, F28335DSP with LCD12864 is connected, fault message, after F28335DSP processes, is shown on LCD12864 by the fault message gathered.This utility model is capable of gathering wind-driven generator fault message, and the information collected is shown after treatment, easy to use, simple to operate.

As preferably, A/D sampling A/D chip selects A/D7656 chip.

The beneficial effects of the utility model are: can gather the fault message of wind-driven generator easily, it is simple to find the fault of generating set early, shorten the time of maintenance, improve safety, easy to use, simple to operate.
