电动机保护的选型存在着电动机与保护器二者怎样合理配用关系，以下提供几个与保护有关的条件、因素，为用户选型时提供参考

1、电动机方面：要先了解的型号规格、电动机功能特性、防护型式、额定电压、额定电流、额定功率、电源频率、绝缘等级等。这些内容基本能给用户如何正确选择与使用电机保护器提供了参考依据。

2、环境条件：主要指常温、高温、高寒、腐蚀度、震动度、风沙、海拔、电磁污染等。

3、电动机用途：如风机、水泵、空压机、车床、油田抽油机等不同负载机械特性，如水泵电机保护器，就应该具备欠载功能，当水00-130-547泵将水抽完时，保护器需要给出保护指令。

4、控制系统方面：控制模式有手动、自动、就地控制、远程控制、单机独立运行、生产线集中控制等情况。启动方式有直接、降压、星三角、00-130-547频敏变阻器、变频器、软起动等启动方式。

5、其他方面：用户对现场生产监护管理是比较随意还是严谨，非正常性的停机对生产影响的严重程度等。

与电机保护器的选用有一定相关因素的还有很多，如安装位置、电源情况、与配电系统的配合等;还要考虑是对新购电机保护器，还是对00-130-547电动机保护升级，还是对事故电动机保护的完善等;还要考虑电动机保护方式改变的难度和对生产影响程度;需根据现场实际工作条件综合考虑电机保护器的选型和调整。

The selection of motor protection has a reasonable relationship between the motor and the protector. The following provides several conditions and factors related to protection to provide a reference for users when selecting

1, motor: to understand the model specifications, motor functional characteristics, protection type, rated voltage, rated current, rated power, power frequency, insulation level, etc. These contents can basically provide a reference basis for users how to correctly select and use motor protectors.

2, environmental conditions: mainly refers to room temperature, high temperature, high cold, corrosion, vibration, wind sand, altitude, electromagnetic pollution, etc.

3, motor use: such as fans, pumps, air compressors, lathes, oil field pumping units and other different load mechanical characteristics, such as pump motor protector, it should have underload function, when the water 00-130-547 pump will be pumped out, the protector needs to give protection instructions.

4, the control system: the control mode has manual, automatic, local control, remote control, stand-alone independent operation, centralized control of the production line, etc. Starting methods include direct, buck, star triangle, 00-130-547 frequency sensitive rheostat, frequency converter, soft start and other starting methods.

5, other aspects: the user of the on-site production monitoring management is more casual or rigorous, abnormal shutdown on the production of the severity of the impact.

There are many factors related to the selection of motor protectors, such as installation position, power supply situation, and coordination with the distribution system; It is also necessary to consider whether to purchase a new motor protector, or to upgrade the protection of the 00-130-547 motor, or to improve the protection of the accident motor; Also consider the difficulty of changing the motor protection mode and the degree of impact on production; The selection and adjustment of motor protectors should be considered comprehensively according to the actual working conditions on site.
