摘要： To carry out a non-destructive test for testing insulation of a small-size electric machine having a coil, a surge voltage is applied to the coil of the electric machine mounted in a decompression tank whose inner pressure is kept from 15 to 25 [Torr] so as to generate glow discharge in case there exists a flaw in the coil.

摘要： A corrona test set has at least a reactor and power separation filter placed in an oil-filled conductive tank of a conductive material such as sheet steel. The exciter optionally may also be placed in the same tank enclosure which is of much smaller size than the equivalent voltage rating test set in air. High voltage taken from the circuit passes out of the tank through high voltage bushings. A preferred form of bushing is a quick coupling cable receiving device having an insulator extending into the tank and a frustoconical metallic extension extending away from the tank with a tubular internal wall connected to these respective parts at opposite ends to form a further oil-filled compartment separate from the tank. A temporary cable termination may be applied to a cable which enables a tubular outer piece to supply rigidity and guidance within the tubular inner wall of the bushing to facilitate contact between the bushing high voltage conductor at the insulator at the tank end of the bushing and the coaxial conductor within the cable. A clamping and sealing ring is provided to hold the terminated cable in position so the demineralized and deionized water can be circulated through the entire space between the cable itself and the inner wall of the oil-filled bushing compartment.
摘要翻译： Corrona测试仪具有至少一个反应器和功率分离过滤器，放置在导电材料如钢板的充油导电槽中。励磁机可选地还可以放置在与空气中设定的等效额定电压试验件相比尺寸小得多的相同的箱体中。从电路取出的高电压通过高压套管流出水箱。衬套的优选形式是快速耦合电缆接收装置，其具有延伸到罐中的绝缘体和延伸远离罐的截头圆锥形金属延伸件，其中管状内壁在相对端连接到这些相应部件，以形成另外的充满油的隔室与坦克分离。临时电缆终端可以应用于电缆，其使得管状外部件能够在衬套的管状内壁内提供刚性和引导，以便于在衬套的罐端处的绝缘体处的衬套高压导体与衬套的高压导体之间的接触电缆内的同轴导体。提供夹紧和密封环以将端接的电缆固定就位，使得软化和去离子水可以在电缆本身与充油衬套隔室的内壁之间的整个空间中循环。

摘要： Dielectric testing of rubber or plastic gloves, particularly an apparatus for suspending a plurality of pairs of water-filled gloves, then immersing the gloves into a water test tank. A high voltage test circuit includes a source of electrical power connected to the water test tank and a plurality of individual electrodes extending into each water-filled glove. Individual test circuits for each electrode enable continued testing, notwithstanding failure or removal of any one glove.

摘要： A cylindrical container for receiving an insulating or cooling medium for electrical apparatus to be tested for resistance to electrical breakdown. The medium enters and leaves the container through two valved apertures. Closure members are fluid-tightly mounted over the two ends of the container, and a pair of electrodes are arranged in the container to form a spark gap therebetween extending parallel to, or coaxially with, the longitudinal axis of the container. Each electrode is carried by a rod held in a respective closure member and a test voltage is applied to the electrodes from the outside through the electrode rods.
