Dc switch setting device used in subway dc power supply system of high-speed dc circuit breaker tripping current value and tripping time setting test, the efficient operation of protective relay parameter test, can output up to 20000 a dc high current (adjustable).
Cable fault testing device is composed of four units: unit, pursuit, and fault location identification unit and fault fixed-point units, high voltage signal.Applicable to all different section below 35 kv, different media and all kinds of power cable, coaxial cable of the high frequency of low resistance, short circuit, open circuit disconnection fault as well as the high resistance leak and high impedance arc fault.Can also be used for local cable short circuit, open circuit and mixed line fault detection.
YN - SR series series resonance device used in power cable, generators, GIS switch, transformer and so on pressure test, pressure test of a new method and trend of electricity, rail transit at home and abroad has been widely used.
Device by the variable frequency source, excitation transformer, high voltage reactor, high voltage divider, compensation of capacitor.
Power frequency withstand voltage test device is controlled by power frequency test box and light oil immersion, SF6 inflatable, dry testing transformer, it is widely used in power supply enterprises, large factories, metallurgical, power plants, railways and other industries, the zinc oxide lightning arrester, power cable, transformer power equipment in power frequency withstand voltage test and need high voltage occasions.
SPC ultra-low frequency high voltage generator 0.1 Hz low frequency withstand voltage test in alternative power frequency withstand voltage test, not only can have the same equivalence, much less and the volume of equipment, greatly reduce the weight, the theoretical capacity is about one over five hundred of the power frequency, and the operation is simple, and the power frequency test more than superiority.
YN - DG series dc high voltage generator is according to the new China power unemployment standard DL/T848.1-2004 "the dc high voltage generator general technical conditions" magnetic blow for zinc oxide lightning arrester, lightning arrester, power cable, such as generator, transformer, switch equipment research and development production of dc withstand voltage test.The device is composed of the control unit and the voltage divider, applicable to the power sector, mining, metallurgy, iron and steel enterprises.
