This paper propose a new computer method-impedance measuring method which is modified by the phase of fault current components. Under two-sources line conditions, the new method can completely eliminate errors which usually exist in generally impedance or reactance measuring methods owing to the load currents and fault risistances, and also can determine the distance from the measuring terminal to fault point with a high order of accuracy only by using current and voltage informations...

本文提出了高压输电线故障点距离的一种新的精确的计算机算法——故障电流分量相位修正阻抗法。对于双侧电源线路,利用新算法。可以完全消除一般阻抗法和电抗法中,由于负荷电流和过渡电阻引起的误差,且只用线路测量端的电气量就能十分精确地求出该端到故障点的距离。 新算法还可以进一步发展成为一种具有高度避越负荷电流和过渡电阻影响性能的计算机距离保护的新算法。 通过在220KV,243公里长和130KV,47.3公里长的两条高压输电线模型上,用CK-710小型控制计算机和“频果”Ⅱ型微型计算机模拟在各种不同负荷电流、过渡电阻和故障距离情况下的各种类型故障试验,所得结果完全证实了新方法的高度精确性。

The inhibiting effect of benzothiazole(BT)and 2-mereaptobenzothiazole (MBT)and the effect of -SH group in this respect on the corrosion of a car- bon steel in HCl solutions at various concentrations and temperatures were investigated.It is shown that the inhibiting effect of MBT is much more pro- nounced than that of BT due to increased surface activity of BT raised by -SH group.Langmiur isotherm equation is observed by both compounds ad- sorbed on steel surface when their concentrations in HCl solutions are not very high.The values of the equilibrium constant B of the adsorption process were determined at θ=0.5.It was found the value of B for MBT (10~5 is of one order of magnitude higher than that for BT(10~4).Impedance measure- ments showed that for both compounds the data of electrode boundary capa- citance which vary with the value of θ fall on the same straight line,and the same value of boundary capacitance (14μF/cm~2)was obtained by extra- polating the experimental data to θ=1.These facts imply that there are no changes in the characteristics of adsorption and the mode of arrangements of the molecules adsorbed on the electrode surface when the -SH group is intro- duced onto the BT.Polarization measurements indicated that both inhibitors belong to the mixed type with predominant anodic control.However,the inhibitive action to the cathodic reaction of the corrosion process is some- what strengthened by introducing the -SH group onto BT molecules.

本工作研究和比较了苯并噻唑与2-巯基苯并噻唑在 HCl 溶液中对碳钢腐蚀的缓蚀行为。以探讨巯基(-SH)的作用。结果表明,巯基的引入明显地改善了苯并噻唑的缓蚀性能。这种作用主要是通过提高苯并噻唑的表面活性而达到的。琉基的引入并没有改变苯并噻唑的吸附规律和在碳钢电极上的排列方式。极化曲线的结果表明,二者都是以抑制阳极过程为主的混合型缓蚀剂。但是,巯基的引入明显地增加了苯并噻唑对碳钢腐蚀的阴极过程的抑制能力。
