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，当其在超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。避雷器由1个底座、2个元件、1个均压环组成。

Metal oxide surge arrester consists of zinc oxide varistors and would be sealed in porcelain housing without any gaps. 1 base，2 units, 1 grading ring .

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 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 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.
