The reasons why wind gear oil needs to be imported are as follows:
1. Imported wind gear oil generally uses high-quality base oil and additives, whose performance is higher than that of domestic brands and can be used for a long term. Maintains stability, wear resistance and oxidation resistance at high temperatures, thereby increasing the life and reliability of the generator.
2. Wind gear oil plays a lubricating and protective role in the transmission part of the wind turbine, ensuring the normal operation of the generator. Since the working environment of wind turbines is relatively harsh and they must withstand extreme conditions such as long-term operation at high speed, high temperature and heavy load, the quality requirements for the gear oil are also very high.
It depends on the insulation level of the motor. Class B is 130 degrees and Class F is 155 degrees.
A motor refers to an electromagnetic device that converts or transmits electrical energy according to the law of electromagnetic induction. Its main function is to convert mechanical energy into electrical energy to generate motor torque, which can be used as power. for electrical appliances or various machine sources.
At present, the most commonly used method is to use thermal energy, hydropower, etc. to drive the rotor of the generator to produce electricity. As wind power generation technology becomes more and more mature, wind power is slowly entering our society. lives.
The types of working power supply are divided into DC motors and AC motors. c current motorsontinu are motors that rely on DC operating voltage and are widely used in radio recorders, VCRs, DVD players, electric shavers, hair dryers, etc. Electronic watches, toys, etc.
The working principle of a DC generator is to convert the alternating electromotive force induced in the armature coil into a DC electromotive force when it is extracted from the brush end through the commutator and the switching action of the brush. .principle.
The direction of the induced electromotive force is determined according to the right hand rule (the lines of the magnetic field point towards the center of the hand, the thumb points towards the direction of movement of the conductor and the four other fingers indicate the direction of the electromotive force induced in the conductor).
