Mechanical Calculation and Test on Conductor of Extra High Voltage Substation 超高压变电站导线力学计算与试验
In case that the design code is modified, in which the allowable heating temperature of the conductor is determined to 80 ℃, the test on conductor HT creepage and service life should be implemented and trial operation is also needed in combination of the practical lines. 若修改设计规程,将导线发热允许温度确定为80℃,为安全起见,仍需进行导线高温蠕变及使用寿命的试验研究,并结合实际线路进行试运行。
Fatigue Test Method of Conductor under Compound Alternating Stress 复合交变应力条件下的导线疲劳试验方法
No brand breakage occurs after fatigue test on the conductor equipped with the pre-twisted suspension clamp and brand breakages occur to the conductors equipped with pre-twisted wire + bolt type suspension clamps; 采用预绞式悬垂线夹的导线,疲劳试验结果没有断股,采用预绞丝+螺栓型悬垂线夹的导线均有断股;
Spark test voltage values given by the potential difference between the test electrode and the conductor of the core or cable under test shall be specified in the cable standard. 火花试验时,电极与被测试电线或电缆之间的电位差的值在电线标准中有明确规定。
