在工频和冲击电压下,湿度对空气间隙和绝缘子放电的影响

Gaoya dianqi, 1974
在工频电压约700千伏(有效值),冲击电压约1500千伏以下,对直径为1米的球间隙、棒间隙、悬式绝缘子以及支柱绝缘子,进行了湿度影响试验研究。并得出了交流电压下湿度对圆柱式绝缘子、冲击电压下湿度对针尖——平板间隙的影响数据。 这些实验数据虽然是有限的,但足以得出湿度对放电电压实际是有影响的结论。特别是湿度高的时候,某些间隙和绝缘子工频放电电压将下降。因此,过去常用的负的校正系数,现应用正的校正系数去代替。 除了球间隙外,正冲击电压下得出的数据表明:随着湿度的增加,放电电压随之增加。负冲击电压下的湿度影响,

增塑剂对坯料性能的影响

Dianci bileiqi, 2006
测试了添加两种不同粘度增塑剂对坯料泥浆性能、吸湿性能及其它性能的影响,结果表明,在相对湿度较低的条件下,高粘度增塑剂（干料0.8%的含量）的加入对坯料的吸湿性能有影响;在相对湿度较高的条件下,高、低粘度增塑剂（干料0.8%的含量）的加入对坯料的吸湿性能均有影响,且高粘度增塑剂的影响较明显。两种增塑剂对坯料其它性能的影响基本相同。建议增塑剂的加入量应结合坯料中粘土的可塑性能而定,当坯料中粘土的可塑性能满足生产工艺条件时,可以适当减少增塑剂的加入量。
