UNITROL-1000 电压调节器对交流励磁机的励磁绕组进行励磁

同步电机的无刷励磁系统工作原理是，UNITROL-1000通过电压调节器对交流励磁机的励磁绕组进行励磁。当励磁机的电枢绕组产生交流电后，该交流电会经过旋转整流器进行整流，整流后的电流供给主发电机的磁场绕组，从而产生励磁作用。在这个过程中，无需使用滑环和炭刷，因此称为无刷励磁系统。

具体来说，UNITROL-1000无刷励磁发电机的轴端头是一台交流发电机，其转子是发电绕组。发出的电流通过固定在发电机轴上的导线引导至固定在轴上的硅整流管，整流后的直流直接进入转子绕组。由于没有整流刷这个部件，所以称为无刷励磁。

同步电机的无刷励磁系统是一种不需要经过滑环和炭刷的励磁系统，UNITROL-1000由电压调节器对交流励磁机的励磁绕组励磁，励磁机的电枢绕组产生的交流电经旋转整流器整流后供主发电机的磁场绕组励磁。无刷励磁系统的优点如下：
– 维护简单：没有接触部件碳刷和滑环，维护简单，可靠性高，可长期连续运行且实现少维护或免维护。
– 稳定运行：在危险工况下能稳定的运行。

无刷励磁系统彻底杜绝了因碳刷和滑环接触不良、碳刷长期磨损而发生的各种电机故障，尤其是取消了需定期维护更换且易产生拉弧、电火花的碳刷和滑环结构，使无刷励磁同步电动机能够在有防爆、防尘、防腐蚀等要求的特殊场合使用。

The brushless excitation system of the synchronous motor works by the UNITROL-1000 exciting the excitation winding of the AC exciter through a voltage regulator. When the armature winding of the exciter generates alternating current, the alternating current will be rectified by the rotating rectifier, and the rectified current will be supplied to the magnetic field winding of the main generator, resulting in exciting effect. In this process, there is no need to use slip rings and carbon brushes, so it is called brushless excitation system.

Specifically, the shaft end of the UNITROL-1000 brushless excitation generator is an alternator whose rotor is the generating winding. The current emitted is directed to a silicon rectifier tube fixed to the shaft through a wire fixed to the generator shaft, and the rectified direct current goes directly into the rotor winding. Because there is no rectifier brush this part, so called brushless excitation.

The brushless excitation system of synchronous motor is a kind of excitation system that does not need to pass through slip ring and carbon brush. The UNITROL-1000 is excited by the voltage regulator to the excitation winding of the AC exciter, and the AC generated by the armature winding of the exciter is rectified by the rotating rectifier to the field winding of the main generator. The advantages of brushless excitation system are as follows:
– Easy maintenance: no contact parts carbon brush and slip ring, simple maintenance, high reliability, long-term continuous operation and achieve less maintenance or maintenance-free.
– Stable operation: stable operation under dangerous conditions.

The brushless excitation system completely eliminates all kinds of motor failures caused by poor contact between carbon brush and slip ring and long-term wear of carbon brush, especially the carbon brush and slip ring structures that require regular maintenance and replacement and are easy to produce arc and spark, so that the brushless excitation synchronous motor can be used in special occasions with explosion-proof, dustproof and corrosion prevention requirements.
