所屬類別：變壓器.發電機測試儀器

参考标准：DL/T 962-2005，DL/T 1154-2012，GB/T 1409-2006，JJF 1095-2002

1、仪器采用复数电流法，测量电容、介质损耗及其它参数。测试结果精度高，便于实      现自动化测量。
2、仪器采用了变频技术来消除现场50Hz工频干扰，即使在强电磁干扰的环境下也能测      得可靠的数据。
3、儀器采用大屏幕液晶顯示器，測試過程通過漢字菜單提示既直觀又便于操作。
4、仪器操作简便，测量过程由微处理器控制，只要选择好合适的测量方式，数据的测      量就可在微处理器控制下自动完成。
5、一體化機型，內附標准電容和高壓電源，便于現場測試，減少現場接線。
6、仪器测量准確度高，可满足油介损测量要求，因此只需配备标准油杯，和测试      线即可实现油介损测量。
7、设CVT测试功能，可实现CVT的自激法测试，无需外置附件，只需一次测量，C1,C2的      电容和介损全部测出。
8、反接線測試采用ivddv技術,消除了以往反接線數據不穩定的現象。
9、具有反接线低压屏蔽功能，在220kV CVT 母线接地情况下，对C11 可进行不拆线     10kV反接线介损测量
10、具有测量高电压介损功能，能够使用高压变压器或串联谐振进行超过10kV电压的介      损试验。
12、接地保护功能，当仪器不接地线或接地不良时，仪器不进入正常程序，不输出高      压。过流保护功能，在试品短路或击穿时仪器不受损坏。
13、触电保护功能，当仪器操作人员不小心触电时候，仪器会立即切断高压，保障试验      人员的安全.

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.
