避雷器，surge arrester。1）用于保护电气设备免受高瞬态过电压危害并限制续流时间也常限制续流幅值的一种电器。本术语包含运行安装时对于该电器正常功能所必须的任何外部间隙，而不论其是否作为整体的一个部件。

2024年12月27日 · Surge arresters are protective devices that limit the voltage on the equipment by discharging (or) bypassing surge current induced by lightning or a power surge. IEEE standard C62.11 & IEC standard 60099-4 specify the requirements for surge arresters.

2022年8月12日 · A surge arrester, as the name suggests, is a device that protects other electrical equipment by “arresting” or discharging surge currents brought about by external (e.g. lightning) or internal (switching events) forces. It is also called a surge protection device (acronym: SPD), or less commonly, a voltage surge suppressor (TVSS).

Key specifications that characterize this device are: the clamping voltage, or the transient voltage at which the device starts functioning, the Joule rating, a measure of how much energy can be absorbed per surge, and the response time.

2021年12月2日 · A surge arrester is a tool that is used to provide protection for electrical devices from high voltage transients which are produced either by internal/external activities. This is also termed a surge protection device which comes under the classification of a protection device in distribution systems and power transmission domains.

Surge arrester is a voltage limiting device installed inside the installation equipment panel to protect the insulation, equipment and machines not only from lightning, but also from transient voltage produced by switching, sparks, load shading …

Surge arresters are used to protect high-voltage equipment in substations, such as transformers, circuit breakers, and bushings, against the effects of overvoltages caused by incoming surges. Such overvoltages

Surge arresters are used to protect high-voltage equipment in substations, such as transformers, circuit breakers and bushings, against the effects of lightning and switching surges. Surge arresters are connected close to, and in parallel, with the equipment to be protected.

Definition: A protective device that is used to protect the electrical power system from surges caused by lightning is known as surge arrester. It includes two terminals like high voltage and ground.

Surge arresters are critical protective devices used to shield electrical systems from high-voltage transients, such as lightning strikes or power surges. By redirecting excess voltage safely to the ground, surge arresters help prevent equipment damage and maintain electrical system stability.
