保护器是一种装置，主要用于保护电器设备免受过载、过流、短路等电气故障的影响。

• Translation: A protector is a device that is mainly used to protect electrical equipment from electrical faults such as overload, overcurrent, and short circuit.

它能够在电器遭遇瞬间高电压的异常情况下智能启动内部保护装置，确保后端用电器的用电安全。

• Translation: It can intelligently activate internal protection mechanisms in the event of an instantaneous high voltage anomaly in electrical equipment, ensuring the safety of the downstream electrical appliances.

保护器可以根据不同的需求选择，分为家用保护器和机械之类的保护器。

• Translation: Protectors can be selected based on different needs, including household protectors and protectors for machinery and similar equipment.

电子仪器和电动机保护器则提供更具体的保护，如给电机全面的保护控制，在电机出现过流、欠流、断相、堵转、短路等情况时予以报警或保护控制。

• Translation: Electronic instrument and motor protectors provide more specific protection, such as comprehensive protection and control for motors, and provide alarms or protective control in the event of motor overcurrent, undercurrent, phase loss, stalling, short circuit, and other conditions.

电器保护器，又称过压保护器、高压保护器、家电保护器，保护各类电器不被高压或低压烧坏，当供电电源出现浪涌、电压不稳等问题时，立即断开电源，避免电器设备被烧毁以及电器火灾的发生。

• Translation: Electrical protectors, also known as overvoltage protectors, high-voltage protectors, and household electrical protectors, protect various electrical appliances from being damaged by high or low voltage. When issues such as power supply surges or unstable voltage occur, they immediately disconnect the power supply to prevent electrical equipment from being burned out and electrical fires from occurring.

漏电保护器，简称漏电开关，用于在设备发生漏电故障时及时断电，保护线路或电动机的过载和短路，也可在正常情况下作为线路的不频繁转换启动之用。

• Translation: A leakage protector, also known as a leakage switch, is used to promptly disconnect the power supply when a leakage fault occurs in the equipment, protecting the line or motor from overload and short circuit. It can also be used for infrequent switching and starting of the line under normal conditions.

浪涌保护器，也叫防雷器，为各种电子设备、仪器仪表、通讯线路提供安全防护，防止浪涌对回路中其他设备的损害。

• Translation: A surge protector, also known as a lightning arrester, provides safety protection for various electronic devices, instruments, and communication lines, preventing surges from damaging other equipment in the circuit.

保护器的种类还包括过载保护器和过流保护器，它们能够避免电气设备因为长时间运行而超载或过流而发生损坏。

• Translation: The types of protectors also include overload protectors and overcurrent protectors, which can prevent electrical equipment from being damaged due to overload or overcurrent caused by prolonged operation.
