电缆护层保护器的作用
The function of cable sheath protector
电缆护层保护器是一种专门用于保护电缆免受损害的设备。它能够监测电缆的运行状态，及时发现电缆的故障和潜在隐患，从而保障电力系统的稳定运行。在电力系统中，电缆护层保护器的主要作用是保护电缆免受短路、过载、漏电等故障的影响，延长电缆的使用寿命。
Cable sheath protector is a device specifically designed to protect cables from damage. It can monitor the operation status of cables, timely detect cable faults and potential hazards, thereby ensuring the stable operation of the power system. In the power system, the main function of cable sheath protectors is to protect cables from faults such as short circuits, overloads, and leakage, and to extend the service life of cables.
电缆护层保护器的分类
Classification of cable sheath protectors
电缆护层保护器按照其工作原理和特点，可以分为以下几种类型：
Cable sheath protectors can be classified into the following types based on their working principles and characteristics:
1. 金属氧化物避雷器：这种保护器利用金属氧化物电阻的特性，在遇到电压峰值时，迅速将电流导引至地面，从而保护电缆免受过电压的损害。
1. Metal oxide lightning arrester: This type of protector utilizes the characteristics of metal oxide resistors to quickly direct current to the ground when encountering voltage peaks, thereby protecting cables from overvoltage damage.
2. 泄漏电流保护器：这种保护器通过监测电缆的泄漏电流，来判断电缆的运行状态。当发生漏电故障时，保护器会自动切断电源，防止故障扩大。
2. Leakage current protector: This protector monitors the leakage current of the cable to determine its operating status. When a leakage fault occurs, the protector will automatically cut off the power supply to prevent the fault from expanding.
3. 温度传感器：这种保护器通过监测电缆的温度，来判断电缆的运行状态。当电缆温度过高时，保护器会自动报警或切断电源，防止火灾等事故的发生。
3. Temperature sensor: This protector monitors the temperature of the cable to determine its operating status. When the cable temperature is too high, the protector will automatically alarm or cut off the power supply to prevent accidents such as fires.
