Wind power generation
As a clean and renewable energy source, wind energy is receiving more and more attention from all countries in the world. Its huge amount of energy, the global wind energy is about 2.74 × 10 ^ 9MW, of which the available wind energy is 2 × 10 ^ 7MW, 10 times larger than the total amount of water energy that can be developed and utilized on the earth. The wind's kinetic energy is transformed into mechanical kinetic energy, and then the mechanical energy is converted into electric power. This is wind power generation. The principle of wind power generation is to use wind power to drive the rotation of the windmill blades, and then increase the speed of rotation through the speed increaser to promote the generator to generate electricity. According to the current windmill technology, about three meters per second of the breeze speed (the degree of breeze), you can start generating electricity. Wind power is forming a boom in the world because wind power does not require the use of fuel or radiation or air pollution. The slip ring is responsible for the power of the whole system in the wind power generation system. The control signal and data transmission function are the key components in the whole fan system. The through-hole small wind power slip ring is suitable for the yaw rotation conduction of the horizontal axis series wind turbine. .
Wind power slip ring working principle: Wind power slip ring is powered by air flow, and the kinetic energy of air flow is called wind energy. The main principle of utilization at this stage is to turn the kinetic energy of the wind into a rotating motion through a windmill to drive the wind turbine to generate electricity. During the working process of the wind turbine slip ring, the change of its main parameters will have a great relationship with its working stability, reliability and life, and sometimes it will have a great impact. Among the application process of wind power slip ring, we should pay attention to the installation of wind turbine slip ring, it is important to pay attention to the seal, waterproof is the key, if the waterproof is not good, because the wind power slip ring is installed outdoors for a long time Time, waterproof failure, it is easy to cause short circuit, affecting the safety of product use, and sometimes even more serious consequences. When installing, leave enough room for the internal space of the gyro rotor to be larger. Consider fixing the mounting position of the brush holder for more flexibility.
Wind power generation is inseparable from the wind power slip ring. The wind power slip ring belongs to a sub-category of conductive slip rings and belongs to high-tech products. The wind power slip ring is a rotating joint component of the connecting part of the rotating blade and the main shaft in the wind power generation equipment. This kind of component is the only channel connecting the signal between the fan and the fan. The data of many sensors must be transmitted between the joints through the wind turbine slip ring, and this is the only component that needs different movements. It is prone to wear and tear. There is a problem with this part, and the entire wind power equipment is completely scrapped. Therefore, the position and role of the wind power slip ring in wind power equipment is very important.
Wind power slip rings are used in various fields:
1. Small generator slip ring;
2, encoder slip ring;
3. Wind power generation equipment;
4, heavy machinery, robotic arm;
5. Medical equipment;
6, smart appliances;
7, lighting display equipment.
Wind power slip ring is responsible for the pitch control power, control signal and data transmission function of the whole system in the wind power generation system. It is a very key component in the whole fan system. Its precision, reliability and working life directly affect the wind power generation system. Performance. Because of the environmental characteristics of the wind power system, the wind power slip ring must have good characteristics such as low temperature resistance, high humidity, corrosion resistance, impact resistance, vibration resistance, long life, stable performance and no maintenance.
