三相组合式过电压保护器各种类型如何区分
How to distinguish various types of three-phase combined overvoltage protectors
1、型号定义：三相组合式过电压保护器的型号定义通常包含了电压等级额定电流、保护特性等关键参数。不同制造商的型号命名规则可能有所不同，但一般应遵循国际或国家标准。型号定义的主要目的是为用户提供清晰的设备信息，以便在选择和使用时能够匹配系统需求。
1. Model definition: The model definition of a three-phase combined overvoltage protector usually includes key parameters such as voltage level, rated current, and protection characteristics. The naming conventions for different manufacturers may vary, but generally should follow international or national standards. The main purpose of model definition is to provide users with clear device information so that they can match system requirements when selecting and using.
2、结构形式：三相组合式过电压保护器的结构形式通常包括一体化和分体式两种。一体化结构将保护器与电气设备紧密结合，安装简便，适用于空间有限的场合。分体式结构则通过连接电缆将保护器与电气设备分离，便于维护和更换。
2. Structural form: The structural form of three-phase combined overvoltage protectors usually includes two types: integrated and split. The integrated structure tightly integrates the protector with electrical equipment, making installation simple and suitable for situations with limited space. The split structure separates the protector from the electrical equipment through connecting cables, making it easy to maintain and replace.
3、使用环境：使用环境对选择三相组合式过电压保护器具有重要影响。用户需要考虑设备所处环境的温度、湿度、海拔、污染成都等因素，选择适合的保护器类型。
3. Usage environment: The usage environment has a significant impact on the selection of three-phase combined overvoltage protectors. Users need to consider factors such as temperature, humidity, altitude, and pollution in the environment where the device is located, and choose the appropriate type of protector.
