1、330kV系列交流无间隙金属氧化物避雷器Silicone Rubber Housed Metal Oxide Surge Arrester Without Gap for AC System for Series 330kV- 330kV使 用 说 明 书 Operation Instruction 南阳金冠电气有限公司Nanyang Jinguan Electric Co., Ltd. 一、 用途. Usage. 330kV系列交流无间隙金属氧化物避雷器（以下简称避雷器）是用来保护相应电压等级的交流电气设备免受雷电过电压和操作过电压损害的保护电器。Series 3300kV silicone

2、 rubber housed Metal Oxide Surge Arrester without gap for AC System (hereinafter referred to as Surge Arrester), is used in power system to protect those AC electric equipments with corresponding voltage such as transformers and distributors against the lightning over-voltage and operating over-volt

3、age.- 330kV ( - ) .产品执行标准：GB11032-2010交流无间隙金属氧化物避雷器。Executive Standard: GB11032-2010 Metal Oxide Surge Arrester Without Gap for AC System. : GB11032-2010 - .二、 使用条件.Service Conditions. 1. 适用于户内或户外 ；For indoors and outdoors; . 2. 环境温度（40 40）oC ；Ambient air temperature : -40+40 (-40 +40) oC;3. 太阳光最大辐射

4、强度为1.1kW/m2 ；Maximum solar radiation intensity not exceeding 1.1kW/m2 1,1 kW/m2.4. 海拔高度不超过1000m ；Altitude not exceeding 1000m; 1000 m.5. 交流系统额定频率为（4862）Hz ；Rated frequency for a.c. system : 48Hz62Hz; (4862) Hz;6. 地震烈度8度及以下地区；Earthquake intensity not exceeding 8 degree; 8 ; 7最大风速不超过35ms ；Maximum wind

5、 velocity not over 35m/s; 35 m/s;8长期施加在避雷器端子间的工频电压应不超过避雷器的持续运行电压。Power frequency voltage applied to Surge Arrester terminals long duration not exceeding Surge Arresters continuous operation voltage , .三、 结构和特性. Construction and Characteristic. 该类避雷器由非线性金属氧化物电阻片叠加组装，密封于高压绝缘合成套内，无任何放电间隙。在正常运行电压下，避雷器呈高

6、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内，以保证电气设备的安全运行。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。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、维护简便等特点。This type of arrester consists of zinc oxide nonlinear resistors with good characteristic, and hermetically-sealed in silicone ru

7、bber housing without any gaps. It will be an insulating state under the condition of the normal operating voltage and will be a low resistivity state when it meets the excess voltage and leaks surge current quickly in order to make the residual voltage on the two ends of the equipment be controlled

8、in the provided voltage and ensure the equipment insulation. The arrester has many advantages such as high sensitivity to steepness wave response, large high current impulse withstand capacity, low residual voltage, large discharge capacity, reliability operation, no power-frequency follow current, high anti-pollution, good explosion protection characteristic, small volume , easy transportation and simple service ,and so on . , . , , - , , , . , , . , , , , , .
