概述
SBJY直流接地故障查找儀避免了傳統查找方法的缺點,可以在不影響直流系統工作的情況下實現接地點故障查找。實現了“便捷”、“可靠”、“安全”、“快速”、“在線”、“直接”的有效檢測查找直流系統故障接地點功能。該儀表具有檢測靈敏度高、抗幹擾能力強、體積小、重量輕、使用方便等特點。查找直流系統接地故障時，不需要斷開電源，可實現接地點定位。儀表不但能檢測直流系統接地電阻阻值，還可以檢測直流系統對地電容值。
SBJY直流接地故障查找儀是新型直流接地檢測儀表，廣泛應用于電力、石化、冶金、郵電、鐵道等直流系統接地故障的查找。儀表基本原理：信號發生器對被測對象與地之間發射一個2.5Hz的低頻電壓信號，在故障點處産生一個泄漏電流，接收器接收故障電流，計算接地電阻值和電容值，並顯示在LCD上。該儀表能**消除容性接地假象，是一種多功能、高性能、低價位的智能型儀表。

功能特點
●各種參數鍵盤設定，使用靈活，可隨時更改。
●可根據現場絕緣實際情況設定報警值。
●適用于不同類型的各種直流系統，無電壓等級限制。
●多種采樣接收器任選，滿足不同類型的回路測量，並可以隨時更換。
●測量接地回路電阻值和接地回路電容值，**、准確去除電容假象接地。
●超低頻信號注入，對直流不造成影響。
●低功耗，幹電池供電5小時。
●不需要調試，使用方便。

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.
