WZJ- B2直流接地故障定位儀

概述

采用正弦信號相位超前處理技術和數據轉移算法技術。該儀器具有檢測靈敏度高、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。儀器不但能檢測直流系統接地電阻阻值，還可以檢測直流系統接電容的電容量。爲電力直流系統故障的查尋與定位提供適用可靠的高准確性探測儀器。

能夠適用于任何電壓等級的直流系統，配備了高精度的檢測鉗表，通過對多種信號的高效處理大大提高了檢測範圍與抗幹擾能力；采用了優秀的算法和*的模糊控制計算理論，將被檢測絕緣支路的優勢程度以數值的形式表示出來，充分體現了人工智能的*性；對于接地點位置的斷定，它們更是擁有准確的判斷力，每次檢測都能夠指出接地點位置及方向。

本裝置以系統安全爲首要前提，按行業標准的zui高要求，以可靠的低頻信號方式進行檢測，並在現場進行了大量的實際應用，對系統無任何影響。

發電廠、變電站的直流系統爲控制、保護、信號和自動裝置提供電源，直流系統的安全連續運行對保證發供電有著極大的重要性。由于直流系統爲浮空制的不接地系統，如果發生兩點接地，就可能引起上述裝置誤動、拒動，從而造成重大事故。因此當發生一點接地時，就應在保證直流系統正常供電的同時准確迅速地探測出接地點，排除接地故障，從而避免兩點接地可能帶來的危害。

用于在不斷電情況下查找發電廠、變電站直流系統接地點的准確位置。各種類型的接地故障，均能迅速地查找出接地點，准確率達到100％。

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.
