How to route offshore wind power generation cables and how to waterproof them

1. If you want to prevent the wire from getting wet, it should be installed in a dry environment. If the surrounding environment is too humid, but it cannot be avoided, the wires can be indirectly protected from moisture through cable sleeves.

2. Choose high-quality wire and cable products. High-quality wire products will be better than inferior wire products.

3. Mainly to prevent solid particles and waterproofing. Generally, the protection level of wind turbines is IP54, which means dustproof and waterproof.

There are many forms of motors, but their working principles are all based on the law of electromagnetic induction and the law of electromagnetic force. Therefore, the general principle of its construction is: use appropriate magnetic and electrically conductive materials to form magnetic circuits and circuits that conduct electromagnetic induction with each other to generate electromagnetic power and achieve the purpose of energy conversion. According to the different starting and running modes of motors, they can be divided into capacitor-started single-phase asynchronous motors, capacitor-run single-phase asynchronous motors, capacitor-start-run single-phase asynchronous motors, split-phase single-phase asynchronous motors, and three-phase motors.

According to the structure of the rotor, the motor can be divided into cage induction motor, which is the one you are using (the old standard is called squirrel cage asynchronous motor) and wound rotor induction motor (old standard The standard is called a wound-type asynchronous motor). A squirrel cage is a closed coil.

(1) When a three-phase asynchronous motor is connected to a three-phase AC power supply (each phase differs by 120 degrees in electrical angle), the three-phase stator winding flows through the three-phase symmetrical current and generates the three-phase magnetomotive force (stator Rotating magnetomotive force) and generates a rotating magnetic field, which rotates clockwise along the inner circular space of the stator and rotor at a synchronous speed.

(2) The rotating magnetic field and the rotor conductor have relative cutting motion. According to the principle of electromagnetic induction, the rotor conductor (the rotor winding is a closed path) generates an induced electromotive force and an induced current (the direction of the induced electromotive force is determined by the right hand) Then judge).

(3) According to the law of electromagnetic force, under the action of induced electromotive force, an induced current will be generated in the rotor conductor that is basically consistent with the direction of the induced electromotive force. The current-carrying rotor conductor is affected by electromagnetic force in the magnetic field generated by the stator (the direction of the force is determined by the left-hand rule). The electromagnetic force forms an electromagnetic torque on the motor rotor shaft, driving the motor rotor to rotate along the direction of the rotating magnetic field. When the motor When there is a mechanical load on the shaft, mechanical energy is output outward. Since the magnetic flux in the part without the short-circuit ring is ahead of the magnetic flux in the part with the short-circuit ring, the direction of motor rotation is the same as the direction of the rotating magnetic field.
