Air opening dust accumulation detection method, air opening dust accumulation detection device and power generating unit

Abstract

The invention provides an air opening dust accumulation detection method, an air opening dust accumulation detection device and a power generating unit. The environment temperature is detected through an environment temperature detection device; a temperature detector is used for detecting the temperature in a protection structure; then, a controller is used for collecting the environment temperature and the temperature in the protection structure and judging whether a difference value between the temperature in the protection structure and the environment temperature is greater than or equal to a first threshold or not; when the controller judges that the difference value between the temperature in the protection structure and the environment temperature is greater than or equal to the first threshold value, a first dust accumulation warning signal is outputted, at the moment, the condition that the accumulated dust at an air opening of the protection structure of the power generating unit needs to be cleaned can be known in time, and the blind waiting for manual regular cleaning is avoided, so the problems of the blindness of the manual regular cleaning and non timeliness in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field of maintenance of power generation units, in particular to a dust accumulation detection method at a tuyere, a dust deposition detection device at a tuyere and a power generation unit. Background technique [0002] At present, the container of the photovoltaic power station is a commonly used device, and the internal heat dissipation is generally achieved by adding a cooling fan and using air flow to exchange heat between the inside and outside of the box. In order to ensure good protection, shutters and filter cotton are added to the air inlet of the cabinet. After long-term operation, a large amount of sand and dust will accumulate at the air inlet, which will hinder the entry of external air and reduce the heat dissipation efficiency. In addition, the casing of the inverter itself, which is installed in the container, is also equipped with an air inlet filter. Although it is inside the container, it needs...
