Different types and characteristics of motor protector
Hitcount:803 Release time:2017-05-10
There are many types of common motor protector, including ordinary type, digital control, intelligent monitoring, special type of Chinese Chinese phenotype. Ordinary type motor protector has the advantages of simple structure, setting current value set by a potentiometer knob or pull code switch, circuit using analog, protection curve using the inverse time or time limit characteristics. The main function is to highlight the overload, lack of phase (three phase imbalance) and so on, such as fault protection, the use of indicator lights show that the operation of the use of digital tube display.
The utility model relates to a digital monitoring type motor protector, which is realized by using a single chip microcomputer to realize the intelligent comprehensive protection of the motor, and integrates the protection, measurement, communication and display. Setting current using digital set, to manipulate the control panel button, the user can according to their actual requirements and protection in the field of self correction parameters setting, the use of digital tube as display window, the digital display of the information is not rich enough, this kind of protection device for high-grade community.
Intelligent motor protector Chinese Han phenotype compared with the digital control, which is more perfect functions, humanized configuration. Such products on various parameters, state information, Chinese directly in the control panel unit Chinese LCD display, make the interface more intuitive and eye-catching, can support a variety of communication protocols, meet many start way, to view a variety of information management records. Such protection in the current market is a high-grade type.
Special type motor protector structure, basic protection function, circuit control mode and the general type of digital monitoring and roughly the same type only protector internal circuit output control wiring methods, in order to highlight the special control, wind machine, water pump, pumping machine, lathe.
