过电压保护器主要由几大部分组成，每一部分都各司其职，共同维护电力系统的稳定。首先是电压传感器，这是保护器的“眼睛”，它时刻监测着电网中的电压变化。一旦电网中出现过电压，电压传感器会立即捕捉到这一变化，并向保护装置发送信号。
Overvoltage protectors are mainly composed of several parts, each of which plays its own role in maintaining the stability of the power system. Firstly, there is the voltage sensor, which is the "eye" of the protector, constantly monitoring voltage changes in the power grid. Once overvoltage occurs in the power grid, the voltage sensor will immediately capture this change and send a signal to the protection device.
保护装置则是过电压保护器的“大脑”，它负责接收电压传感器的信号，并根据预设的阈值判断是否需要进行保护动作。当确定出现过电压时，保护装置会迅速响应，切断电源或将电路切换到备用电源，从而避免设备受损。
The protective device is the "brain" of the overvoltage protector, which is responsible for receiving signals from the voltage sensor and determining whether protective action is needed based on a preset threshold. When it is determined that overvoltage has occurred, the protective device will respond quickly, cutting off the power or switching the circuit to a backup power source to avoid equipment damage.
控制装置则负责调节整个保护器的工作状态。它采用先进的微机控制技术，可以实现自动控制和远程监测等功能，使得操作更加便捷、****。
The control device is responsible for regulating the working status of the entire protector. It adopts advanced microcomputer control technology, which can achieve functions such as automatic control and remote monitoring, making operation more convenient and efficient.
此外，电源装置也是过电压保护器不可或缺的一部分。它为主装置提供稳定的工作电源，并在主电源故障时自动切换到备用电源，确保保护器能够持续运行。
In addition, the power supply device is also an indispensable part of the overvoltage protector. It provides a stable working power supply for the main device and automatically switches to the backup power supply in case of a main power failure, ensuring that the protector can continue to operate.
这些部分共同构成了过电压保护器，它们在电力系统中相互协作，共同对抗过电压的威胁。通过限制过电压幅度、吸收能量、提高系统稳定性以及延长设备寿命，过电压保护器为电力系统的安全稳定运行提供了有力保障。
These parts together constitute an overvoltage protector, which cooperates with each other in the power system to jointly combat the threat of overvoltage. By limiting the amplitude of overvoltage, absorbing energy, improving system stability, and extending equipment life, overvoltage protectors provide strong guarantees for the safe and stable operation of power systems.
