    三、结构和特性
    III. Construction & Characteristics
    该类避雷器由非线性金属氧化物电阻片叠加组装,密封于高压绝缘瓷套内,无任何放电间隙。该避雷器设有压力释放装置,当其在**负载动作或发生意外损坏时,内部压力剧增,使其压力释放装置动作,排出气体。该避雷器由1个元件、1个底座组成。
    Metal oxide surge arrester consists of zinc oxide varistors and would be sealed in porcelain housing without any gaps. Surge arrester is equipped with pressure relief device which will operate under increasing pressure resulted from overload impulse or unexpected damage to remove internal gas and prevent from explosion. This surge arrester is consisted of 1 units and 1 base. 
    在正常运行电压下,避雷器呈高阻绝缘状态;当受到过电压冲击时,避雷器呈低阻状态,迅速泄放冲击电流入地,使与其并联的电气设备上的电压限制在规定值,以保证电气设备的安全运行。本避雷器具有陡波响应特性好,冲击电流耐受能力大、残压低、动作可靠、无工频续流、防爆性好、维护简便等特点。
    The surge arrester presents a high resistance state at normal operating voltage. Under the over-voltage impulse, it would be a low resistance status and release the surging current into the earth quickly so as to make the residual voltage of the equipments which are connected in parallel with it to be controlled within the required voltage and ensured the insulation and safety of the equipments. The metal oxide surge arresters have many advantages such as good steep wave characteristics, large capacity of rectangular wave, high operating reliability, low residual voltage, well anti-pollution ability, simple maintenance, etc.

    1. Detection: the preventing checking test should be taken before surge arrester operation and thunder season. The test items are as the followings:
    ⑴ 直流或工频参考电压试验:
    a. D.C. or Power Frequency Reference Voltage Test:
    在避雷器两端施加直流(电压脉动率不大于±1.5%)或工频电压,待流过避雷器的直流或交流阻性电流峰值达到参考电流时,读取电压值,其值不小于标准值。
    Direct current or power frequency voltage (the voltage impulse rate ≤±1.5%) should be applied to both sides of surge arrester. When the D.C. or A.C. resistive current peak value that flowing through the arrester stably at reference current, read the voltage value, and it should not be lower than the standard value.

    The special leakage current testing apparatus for surge arrester or high definition A.C. meter should be used when checking the continuous current value. The whole current virtual value or resistance current peak value which flow through the arrester tested under the continuous operating voltage should not be 2 times larger that the starting value when operating.
    2、维护:按电力系统规程规定执行。
    2. Maintenance: should be executed as the power system regulations.
    七、注意:
    VII. Notice:
