瓷外套金属氧化物避雷器及主要技术参数.doc

瓷外套金属氧化物避雷器及主要技术参数瓷外套式金属氧化物避雷器可用于限制变压器、电容器、真空开关、变压器中性点等的过电压。该产品内部采用了优质半导体材料，高强度棒以及金属压板把电阻片固定在同心圆内，使避雷器整体结构更加牢固，保证了在安装和运输过程中产品内部原件仍然保持良好的接触，减少局部放电量，并且半导体材料形成的保护层使得电阻片避免吸潮，延长了其侧面的有效爬距，从而提高了产品的可靠性，延长了使用寿命。避雷器主要技术参数列表如下： 表一 配电型Y5W 、 Y5WS系列产 品型 号避雷器额定电压系统额定电压持续运行电压直流参考电压U1mA不小于8/20us标称电流下残压方波通流容量2ms 18次4/10us冲击电流容量2次0.75U1mA下泄漏电 流不大于爬电比距高度HKV(有效值)KVKV(峰值)AKAuAmm/KVmmY5WS-7.6/307.6641530100405034250Y5WS-10/3010681530100405034250Y5WS-12.7/5012.7106.62550100405027290Y5W-12.7/5012.7106.62550100405027290Y5WS-16.5/5016.51013.62550100405027290Y5WS-17/50171013.62550100405027290Y5W-17/50171013.62550100405027290表二 电站型Y5WZ 、Y10W系列产 品型 号避雷器额定电压系统额定电压持续运行电压直流参考电压U1mA不小于8/20us标称电流下残压方波通流容量2ms 18次4/10us冲击电流容量2次0.75U1mA下泄漏电 流不大于爬电比距高度HKV(有效值)KVKV(峰值)AKAuAmm/KVmmY5WZ-7.6/277.66414.527200405034250Y5WZ-10/27106814.527200405034250Y5WZ-12.7/4512.7106.62445200405028290Y5WZ-16.5/4516.51013.62445200405028290Y5WZ-17/45171013.62445200405028290Y5WZ-42/134423523.473134200,4006550259701080Y5WZ-51/134513540.873134200,400655025Y5WZ-52.7/13452.73540.873134200,400655025Y10W-100/26010011078145260600,80010050251375Y10W-102/26610211079.6148266600,80010050251375Y10W-108/28110811084157281600,80010050251375表三 电容器型Y5WR系列产 品型 号避雷器额定电压系统额定电压持续运行电压直流参考电压U1mA不小于8/20us标称电流下残压方波通流容量2ms 18次4/10us冲击电流容量2次0.75U1mA下泄漏电 流不大于爬电比距高度HKV(有效值)KVKV(峰值)AKAuAmm/KVmmY5WR-7.6/277.66413.827400655034250Y5WR-12.7/4512.7106.62345400655028290Y5WR-17/45171013.62445400655028290Y5WR-42/134423523.4701344006550259801080Y5WR-51/134513540.873134400655025Y5WR-52.7/13452.73540.873134400655025Y5WR-84/221846667.2121221400,6006550251200Y5WR-90/236906672.5130236400,6006550251200表四 电机型Y5W 、Y2.5W 、Y1.5W系列类别产 品型 号避雷器额定电压电机额定电压持续运行电压直流参考电压U1mA不小于8/20us标称电流下残压方波通流容量2ms 18次4/10us冲击电流容量2次0.75U1mA下泄漏电 流不大于爬电比距高度HKV(有效值)KVKV(峰值)AKAuAmm/KVmm发电机Y5W-4/9.543.153.25.79.5400405028270Y5W-8/1986.36.311.219400405028270Y5W-13.5/3113.510.510.518.731400405028315Y5W-17.5/4017.513.813.824.440400405028315Y5W-20/402015.7515.028.040400405028315Y5W-23/512318.018.031.951400405028315Y5W-25/56.22520.020.035.456.2400405028315电动机Y2.5W-4/9.543.153.25.69.5200405037270Y2.5W-8/1986.36.311.319200405034270Y2.5W-13.5/3113.510.510.518.931200405028315电机中性点Y1.5W-2.4/62.43.151.93.46200405040270Y1.5W-4.8/124.86.33.86.912200405037270Y1.5W-8/19810.56.411.319200405034270Y1.5W-10.5/2310.513.88.414.923200405028270Y1.5W-12/261215.759.617.026200405028315Y1.5W-13.7/29.213.718.011.019.529.2200405028315Y1.5W-15.2/31.715.220.012.221.631.7200405028315表五 变压器中性点型Y1.5W系列产 品型 号避雷器额定电压系统额定电压持续运行电压直流参考电压U1mA不小于8/20us标称电流下残压方波通流容量2ms 18次4/10us冲击电流容量2次0.75U1mA下泄漏电 流不大于爬电比距高度HKV(有效值)KVKV(峰值)AKAuAmm/KVmmY1.5W-60/1446011048851444006550258851200Y1.5W-72/1867211058103186400655025Y1.5W-96/26096220771372604006550251200Y1.5W-144/320144220116205320400,6006550251810327.5KV带间隙金属氧化物避雷器及主要技术参数表一 带串联间隙Y5C系列产 品型 号避雷器额定电压系统额定电压持续运行电压工频放电电压不小于8/20us 5KA冲击残压方波通流容量2ms 18次高 度HKV(有效值)AmmY5C-3.8/13.53.832913.575 , 150250Y5C-7.6/277.664162775 , 150250Y5C-12.7/4512.7106.6264575 , 150290Y5C-22/582218124258400290表二 带并联间隙Y0.5B系列产 品型 号避雷器额定电压系统额定电压持续运行电压直流参考电压U1mA不小于8/20us 冲击残压1.2/50 us冲击放电电压不大于方波通流容量2ms 18次高 度HKV(有效值)KVKVKVAmmY0.5B-7.6/157.66411.51515200 , 400250Y0.5B-12.7/2812.7106.7212828200 , 400315,290Y0.5B-42/794227.531.5607979200 , 400315,290静止补偿装置用成套金属氧化物避雷器及主要技术参数产 品型 号避雷器额定电压系统额定电压持续运行电压直流参考电压U1mA不小于工频参考电压U1mA不小于标称放电电流下残压不大于方波通流容量2ms 18次高 度HKV(有效值)KVKVKVAmmY0.5 W-45/106453541.2676.4451066001200Y0.5WR
