The back of the chassis 1 is connected with a ventilation grille plate 2, which can transmit fresh air through the ventilator 12 to the filter bin 3. There are two filter cottons 5 in the bin to adsorb dust and impurities in the air, so that the clean air is delivered to the air delivery cavity 10 through the delivery pipe 8 and the connecting pipe 9. The air is then transmitted to the arc plate 19 through the air delivery cavity 10. A through hole 20 is provided on the surface of the arc plate 19.

[0028] Wind turbine yaw slip rings are high-power power transmission devices used in megawatt-class wind turbines. They transmit power through sliding electrical contact between the stator and rotor. During this process, the power transmission conductors within the yaw slip rings generate several thousand volts of high voltage. Conventional sensors cannot withstand this high voltage and may break down during use, even risking burnout. Therefore, a temperature sensor that is resistant to high voltage, high temperatures, and oil and water resistance is required to measure the temperature of the transmission conductors.

By real-time monitoring of the temperature and humidity inside the collector ring, the cooling fan and the heating device are reasonably controlled to ensure that the temperature and humidity inside the yaw collector ring meet the operating requirements.

[0030] Principle: The sensor uses a high-precision temperature measurement PT100 chip and high-voltage and high-temperature resistant cables. The chip is sealed and protected with epoxy resin glue, and the outside is wrapped with a Teflon sleeve and insulating film. It can withstand a high voltage of 10,000 volts AC. Tinned copper terminals are used for easy installation and enhanced thermal conductivity.

[0031] Beneficial effects:

[0032] 1) High temperature, high pressure and corrosion resistance;

[0033] 2) Oil and water proof, high protection level;

[0034] 3) High hardness transparent epoxy resin glue provides full protection for the sensor and wire core solder joints and has strong pressure resistance;

[0035] 4) Equipped with tinned copper terminals for easy installation;

[0036] 5) The temperature measurement is fast and responds to temperature changes in a timely manner;

[0037] 6) Effectively solve the problem of temperature collection inside the yaw collector ring.
