击穿点

By detecting high-voltage rectifier circuit in the current point of failure to judge whether the flashover breakdown discharge.

1通过检测高压整流回路中的电流来判断故障点是否闪络击穿放电。

The results shows that the probability distribution of discharge striking points is related to the breakdown voltage,breakdown time and the development of head-on discharge, it is influenced by geometric shape of object, ground resistance, and geometric striking distance.

结果表明，放电击中点的概率分布与上电极对各目的物的击穿电压、击穿时间和迎面放电的发展有关，受目的物几何形状、接地电阻和几何击距等因素的影响。

Most parameters for the mixture antioxidation oil were studied and they were consistent with GB 2536-90, including transparence, smell, density, solidifying point, flash point, viscosity, acids and water-solubility acids;The viscosity of the antioxidation oil at 20℃～90℃was as same as mineral;And the relative permittivity at 30～106Hz was invariable and it was higher than mineral oil so that the electric field of the antioxidation oil paper insulation was more equilibrious.

研究得到了所研制的抗老化变压器油的参数值：透明度、气味、密度、凝点、闪点、运动粘度、酸值及水溶性酸或碱等，均满足变压器油技术标准GB 2536-90的要求；20℃～90℃之间该油运动粘度和矿物油几乎相等；在30～106Hz频率范围内，该油相对介电常数基本维持恒定，且比矿物油相对介电常数略大；其工频击穿电压远高于矿物油。

In view of the superstandard total hydrocarbon problem found in the oil chromatographic analysis for No.

广东粤电流溪河发电有限责任公司1号主变压器通过油色谱分析发现总烃超标，吊罩检查找到引线绝缘击穿故障点，采用磷铜补焊的方法修复烧断引线，及时消除了重大安全隐患。

Full application of this project can save the time for seeking the high voltage porcelain post insulator breakdown points, reduce a half of the power off maintenance time for the electric authority. It can reduce more than YMB 5 billion Yuan of the direct economic loss and more than YMB 120 billion Yuan of the indirect economic loss.

本项目的全面实施可为电力部门免去寻找高压瓷瓶击穿故障点的时间，缩短因停电检修时间二分之一，全国每年可减少直接经济损失 50 亿元以上，减少间接经济损失 1200 亿元以上，提高供电质量，降低外线工劳动强度，减少外线工配备量。

Thermalsteam check, first of all should be based on the symptoms and found that the PLC external inputs,"" 00 "" indicator light hj01 ②to Leung-sing, solenoid valve output indicator "" 00 stays the same, evaluated to PLC output contact "" 00 has breakdown.

停机检查，首先根据故障现象进行判断，发现PLC外围输入电路的&00&、&01&指示灯有规律地亮动，电磁阀输出指示灯&00&一直亮动，判断为PLC输出触点&00&已击穿。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
