1.1本标准适用于工作电压等于或小于600 V rms的系统上过压保护应用的气隙。这些保护装置用于限制平衡或不平衡通信和信号电路上的电压。ANSI/IEEE C62所涵盖的阀门和排出式装置不在本标准范围内。1-1989，交流电力电路用电涌放电器标准。本标准包含一系列用于确定这些气隙装置电气特性的标准试验。1.2本标准中的试验旨在作为ANSI/IEEE Std 100-1996《电气和电子术语标准词典》中定义的设计试验，并提供各种气隙浪涌保护装置之间的比较方法。 对于受避雷器与其相关安装布置相互作用影响的参数，一些试验必须适用于保护器。1.3气隙装置用于在电路中提供过压保护。当超过器件的击穿电压时，其正常的高阻抗状态变为低阻抗状态，以允许浪涌放电电流传导。在设备传导浪涌放电电流后，它会中断系统跟随电流的流动，并返回其高阻抗状态。I如果持续电流不代表正常系统条件，设备将继续提供低阻抗通道，直到外部旁路机构激活，不希望的电流源被切断- 通电，或协调保护电流元件运行。本标准的测试标准和定义为气隙浪涌保护装置的用户和制造商提供了一种通用的工程语言。1.4由于本文中包含的大多数试验中使用的电压和能量水平，所有测量都应被视为危险的，在进行测量时应适当小心。

1.1 This standard applies to air gaps for over-voltage protection applications on systems with operating voltages equal to or less than 600 V rms. These protective devices are designed for limiting the voltages on balanced or unbalanced communication and signaling circuits. Specifically excluded from this standard are valve and expulsion type devices covered by ANSI/IEEE C62.1-1989, Standard for Surge Arresters for Alternating-Current Power Circuits. This standard contains a series of standard tests for determining the electrical characteristics of these air gap devices. 1.2 The tests in this standards are intended as design tests as defined in ANSI/IEEE Std 100-1996, Standard Dictionary of Electrical and Electronic Terms, and provide a means of comparison among various air gap surge protective devices. For those parameters affected by the interaction of the arrester with its associated mounting arrangement, some tests are necessarily applicable to the protector.1 1.3 Air gap devices are used to provide over-voltage protection in electrical circuits. When the device's breakdown voltage is exceeded, its normal high impedance state changes to a low impedance state to allow conduction of the surge discharge current. After the device conducts the surge discharge current, it interrupts the flow of system follow current and returns to its high impedance state. I the event of continuing current not representing normal system conditions, the device continues to provide a low impedance pass until an external bypass mechanism activates, the source of undesired current is de-energized, or a coordinated protective current element operates. This standard's test criteria and definitions provide a common engineering language beneficial to user and manufacturer of air gap surge protective devices. 1.4 Due to the voltage and energy levels employed in the majority of tests contained herein, all measurements should be considered dangerous and appropriate caution should be taken in their performance.
