　　産品介紹：

　　直流系統接地是一種易發生且對電力系統危害較大的故障。直流系統正極接地，可能造成繼電保護誤動，因爲跳閘線圈接直流電源負極，系統再有一點接地或絕緣不良，可能引起保護誤動；直流系統負極接地，系統再有一點接地或絕緣不良，可將跳閘回路或合閘回路短路，造成保護拒動，此時系統發生故障，保護的拒動必然導致系統事故擴大，同時還可能燒壞繼電器的觸點或燒保險。

　　MC-D600型便攜式直流接地故障查找儀是新一代直流接地故障查找仪。它能够适用于电压等级的直流系统，配备了检测钳表，通过对多种信号的处理大大提高了检测范围与抗干扰能力；将被检测绝缘支路的绝缘状况以数值的形式表示出来，充分体现了人工智能的*性；对于直流系统绝缘下降或发生接地位置的断定，具有准确的判断力。

　　直流接地故障查找儀不僅重點解決了直流系統間接接地、非金屬接地、環路接地、正負同時接地、正負平衡接地、多點接地等疑難故障的准確檢測，並且還能准確的顯示系統電壓、對地電壓、接地阻值，真正解決了運行及檢修人員的後顧之憂。

　　MC-D600型便攜式直流接地故障查找儀由信号发生器和信号采集接收器二部分组成，信号发生器与直流系统正负母线和地相连，当直流系统出现接地故障后，它会自动产生一个低频小信号，故障检测器与钳表独立于信号发生器，故障检测器与钳表之间使用连接线相连，通过对待检测支路漏电流信号的采集、分析，从而判断出该支路的绝缘情况。

　　功能特點：

　　1、定位查找金屬接地、非金屬接地、環路接地、正負同時接地、正負平衡接地、多點接地；

　　2、測量顯示直流系統電壓，對地電壓、接地阻值；

　　3、高精度采樣鉗表，對間接接地，高阻接地點定位准確可靠；

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.
