What’s the Motor protection knowledge?
Due to the continuous development of the insulation technology, the design of the motor requires not only increased output, but also requires a reduction in the volume, so that the heat capacity of the new type of motor becomes smaller and smaller, and the overload capacity becomes weaker and weaker; The motor often operates in many ways such as frequent starting, braking, reversing, changing load, etc., and imposes higher requirements on the motor protection device. In addition, the motor has a wider application area and often operates in extremely harsh environments, such as humid, high-temperature, dusty, and corrosive environments. All of this has caused the motor to be more easily damaged, in particular, overload, short circuit, phase loss, brooms and other faults have the highest frequency of occurrence.
The ideal motor protector is not the most functional, nor the so-called most advanced, but should meet the actual needs of the site, to achieve the unity of economy and reliability, with a high performance to price ratio. According to the actual situation of the site, the type and function of the protector are reasonably selected. At the same time, it is considered that the protector is easy to install, adjust, and use. It is more important to select a high-quality protector.
