What to consider when choosing a motor protector
Oct 28, 2022|
View:207chooseMotor protectorThe purpose is to make the motor fully exert its overload capacity, avoid damage, and improve the reliability of the electric drive system and the continuity of production. When the protection requirements can be met, the simpler protection device should be considered first. When the simple protection device cannot meet the requirements, or when higher requirements are placed on the protection functions and characteristics, the application of complex protection devices can be considered. So what issues do we need to consider when choosing a motor protector? Let the motor protector manufacturer give you a detailed introduction.
chooseMotor protectorThe following factors need to be considered.
1) Motor: First of all, you need to understand the model specifications, motor functional characteristics, protection type, rated voltage, rated current, rated power, power frequency, insulation, etc. These contents can basically provide a reference for users on how to correctly use, maintain and select protectors.
2) Environmental conditions: mainly refers to normal temperature, high temperature, extreme cold, degree of corrosion, degree of vibration, sandstorms, altitude, electromagnetic pollution, etc.
3) Motor purpose: mainly refers to the characteristics required for driving mechanical equipment, such as the mechanical characteristics of different loads such as fans, water pumps, air compressors, lathes, oil field pumping units, etc.
4) Control system: The control modes include manual, automatic, local or centralized remote control, stand-alone operation, or production line chain automation program and other working operations. The starting modes include direct, step-down, star-delta, frequency-sensitive rheostat, inverter, soft start and other starting modes.
5) Other aspects: whether the user's monitoring and management of on-site production is casual or rigorous, the severity of the impact of abnormal shutdowns on production, etc.
There are many factors related to the selection of protectors, such as installation location, connection lines, and coordination of electrical appliances in the system, but the main factor is the change in motor working conditions and the degree of influence of control changes on production. According to the above actual working conditions and actual changes, the protector should be reasonably selected and adjusted.
