接地故障快速查找儀大大提高电力系统的安全性和可靠性

更新时间：2024-02-22 点击次数：861次

　　在電力系統的運行和維護中，接地故障是一種常見且具有潛在危險的問題。它不僅會導致設備損壞、電力損耗，還可能引發安全事故。爲了快速定位和處理接地故障，接地故障快速查找儀應運而生。這種先進的檢測設備能夠准確、迅速地找到接地點，大大提高了電力系統的安全性和可靠性。

　　查找儀的主要功能是通過測量土壤中的雜散電流，確定接地故障的位置。當電力系統中發生接地故障時，故障電流會通過接地線流入地面，形成雜散電流。通過測量這些雜散電流的分布和強度，查找儀可以准確地定位接地點，從而幫助維修人員迅速找到故障源並進行修複。

　　接地故障快速查找儀的工作原理是基于电磁感应定律。它由一个发射器和一个接收器组成。发射器向地面发送特定频率的电磁波，当这些波遇到杂散电流时，会产生相应的电磁场变化。接收器则通过测量这些变化来确定杂散电流的位置和强度。此外，现代的查找仪还可以利用计算机技术对接收到的信号进行处理和分析，进一步提高了定位的准确性和速度。

　　在電力系統的應用中，查找儀的優勢非常明顯。首先，它可以在不停電的情況下進行檢測，避免了因停電帶來的損失。其次，它的檢測速度快、准確性高，可以在短時間內找到故障點，減少了維修時間。此外，它還可以在複雜的地形和環境下使用，具有很強的適應性。

　　除了上述功能和应用外，接地故障快速查找儀还具有操作简便、携带方便等优点。它的设计通常考虑到了用户的需求和现场的实际情况，使得操作者可以更容易地进行检测工作。同时，由于采用了便携式设计，查找仪可以轻松携带到不同的现场进行使用。

The captain gave the order to cast off the lines. Hardly had the echo of his words ceased before the lines had fallen. Then he rang the signal to the engineer, and the great screw began to revolve beneath the stern of[Pg 49] the ship. Promptly at the advertised time the huge craft was under way. The crowd on the dock cheered as she moved slowly on, and they cheered again as she gathered speed and ploughed the water into a track of foam. The cheers grew fainter and fainter; faces and forms were no longer to be distinguished; the waving of hats and kerchiefs ceased; the long dock became a speck of black against the hilly shore, and the great city faded from sight. "But there is danger that you will get tired if we keep on much longer about the sights of Canton, and particularly the shopping part of it. Besides, we want to go out and see what there is in Hong-kong, and perhaps we may run across something new in the Chinese part of the city that we shall want to buy. A good many people say that you can buy Canton goods just as cheaply in Hong-kong as in the city they come from. That may be so; but then it is more satisfactory to get them there and have the pleasure of buying them on the spot. "Let's go back," whispered Lilian, and they turned and retraced their steps. The sight of the lovers sealed their lips. Doctor Allingham struggled for a few moments with a strange sense of bigness wanting to escape. Almost it was a physical sensation; as though the nervous energy in his brain had begun to flow independently of the controls that usually guided it through the channels graven by knowledge and experience. It was Lilian who spoke next, and there was a note of pain in her voice. The steam-engine is the most important, and in England and America best known among motive agents. The importance of steam contrasted with other sources of motive-power is due not so much to a diminished cost of power obtained in this way, but for the reason that the amount of power produced can be determined at will, and in most cases without reference to local conditions; the machinery can with fuel and water be transported from place to place, as in the case of locomotives which not only supply power for their own transit, but move besides vast loads of merchandise, or travel. The first principle to be pointed out in regard to belts, to distinguish them from shafts as a means of transmitting power, is that power is communicated by means of tensile instead of torsional strain, the power during transmission being represented in the difference of tension between the driving and the slack side of belts. In the case of shafts, their length, or the distance to which they may be extended in transmitting power, is limited by torsional resistance; and as belts are not liable to this condition, we may conclude that unless there are other difficulties to be contended with, belts are more suitable than shafts for transmitting power throughout long distances. Belts suffer resistance from the air and from friction in the bearings of supporting pulleys, which are necessary in long horizontal belts; with these exceptions they are capable of moving at a very high rate of speed, and transmitting power without appreciable loss. “Mr. Whiteside—and Jeff?” repeated Larry. Infantry." Now you've torn it. Sometimes there were crises of extraordinary violence when he was with difficulty held down in bed, and these at last wore him out. Towards dawn he fell into a troubled sleep. She opened her lips to protest, but the sound died on them, for he stooped and swept her up in his arms. She slipped her hand to his neck to steady herself, and they went forward again towards the south. Young Ralph Bardon had come into the room, and stood by the door while the last verse was being sung. He was there to give an invitation from his father, for every year the Squire provided the choristers with a mild debauch at Flightshot. Robert had been to several of these, and they glittered in his memory—the laughter and games, the merry fooling, the grand supper table gay with candles. What a joke it had been when someone had given the salt to Rosie Hubble instead of the sugar to eat with her apple pie, and when some other wag had pulled away Ern Ticehurst's chair from under him.... No one thought or spoke or wrote of anything else.[Pg 181] If at meetings Reuben tried to introduce Protection or the Franchise, he was silenced even by his own party. The Scott's Float toll-gate became as important as the Sluice or the Brede River or the Landgate Clock had been in other elections, and nothing, no matter of what national importance, could stand against it.
