Method for reducing failure rate of wind vane through wind sensor

Abstract

A method for reducing the failure rate of a wind indicator through a wind sensor comprises the steps of: A, setting the constant temperature of a heater of the wind sensor to be 40-60 DEG C, and installing the wind sensor with the constant temperature set on a wind measuring support; B, coating conductive paste at a connection interface of the wind sensor and the wind measuring support; C, when a cable of the wind sensor enters a cabin cabinet, enabling a protective layer of the cable to need to be stripped out to expose a shielding layer, and then installing the cable on a shielding clip for 360-degree grounding processing; and D, respectively arranging the shielding layers of the connecting lines between the temperature measurement junction box and the cabin cabinet of the generator temperature measurement loop at the temperature measurement junction box and the cabin cabinet, exposing the protective layers of the cables needing to be stripped out of the shielding layers, and then mounting the cables on shielding clips for 360-degree grounding treatment, so that the double ends of the shielding layers of the connecting lines are grounded. By means of the method, the wind indicator fault current can be effectively restrained, the wind indicator fault rate is reduced, and normal operation of a draught fan is guaranteed.

Description

technical field [0001] The invention relates to a wind sensor used in a wind power generation project, in particular to a method for reducing the failure rate of a wind vane by a wind sensor. Background technique [0002] In the sound of a wind power generation in Sunjiazhai, Suizhou, Hubei, there have been multiple on-site feedbacks. In the case of small winds, the units equipped with FT wind sensors frequently reported the failure of the wind vane, which caused the unit to shut down and caused certain economic losses. When the project personnel went to the engine room to check the cause of the failure, they all found the following problems: 1. There were flies and other small insects living in the resonance cabin of the FT wind sensor; 2. The grounding of the connection between the FT wind sensor and the wind measuring bracket could not be effectively connected; 3. , The shielding wire of the FT wind sensor signal cable cannot be effectively connected. In view of this phe...

[0002] In the sound of a wind power generation in Sunjiazhai, Suizhou, Hubei, there have been multiple on-site feedbacks. In the case of light wind, the unit equipped with FT wind sensor frequently reported the failure of the wind vane, which caused the unit to shut down and caused certain economic losses.

When the project personnel went to the engine room to check the cause of the failure, they all found the following problems: 1. There were flies and other small insects living in the resonance cabin of the FT wind sensor; 2. The grounding of the connection between the FT wind sensor and the wind measuring bracket could not be effectively connected; 3. , The shielding wire of the FT wind sensor signal cable cannot be effectively connected

In view of this phenomenon, the pre-technical base analysis preliminarily speculates that the above three reasons are superimposed to cause the wind sensor to trigger the state identification information current (1.4mA), resulting in frequent reports of wind vane failures.
