XJ-SNXL水內冷發電機泄漏電流測試儀，对于发电机，进行直流试验能灵敏有效的发现定子绕组端部缺陷和间隙性缺陷。它以成为发电机绕组绝缘试验中普遍采用的方法。由于大型水内冷发电机汇水管传导电流很大，且根据水质不同，一般在试验电压下电流达20～150mA不等，如果没有足够容量的直流高压发生器，将无法升压。HT-90型系列水內冷發電機泄漏電流測試儀是于发电机，特别是水内冷发电机进行泄漏电流和直流高压试验而研制的。它特别设计了各种干扰电流

XJ-SNXL水內冷發電機泄漏電流測試儀還具有兆歐表功能，由于它的短路電流可≥20mA，足夠滿足水內冷發電機的絕緣電阻和吸收比的測量，是一般搖表無法替代的。

特點：
● 采用中频倍压回路，*应用的PWM脉宽调制技术和大功率IGBT器件，并根据电磁兼容性理论，采用特殊屏蔽、隔离和接地措施，使仪器实现了高品质、便携式，并能承受额定电压放电而不损坏。
● 采用电压大反馈，使電壓穩定度大大提高。同时提高了逆变频率，降低了仪器和倍压筒的体积和重量。更便于携带。
● 测量数据用LCD 320×240点阵大屏幕显示。
● 内置2500V兆欧表功能，可测量吸收比和极化指数，电阻量程0-106MΩ误差≤5%。
● 自带计时器。
● 采用美国、日本等高质量元器件和德国制造的型机箱，抗干扰能力强，美观实用。
● 倍压筒采用德国技术研制，中频变压器经有关专家特殊设计，体积小容量大。
● 采用特殊设计，大大增加了仪器的输出电流和功率，以适应大容量负载的要求。

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.
