In power systems, railway systems and large petrochemical factories and mines, enterprises have a large number of electrical equipment, and most of their internal insulation is oil-filled insulation. The dielectric strength of insulating oil is a routine test that must be measured. In order to meet the needs of the market, our company has independently developed and produced a series of insulating oil dielectric strength testers according to the national standard GB/T507-2002, the industry standard DL429.9-91 and the latest power industry standard DL/T846.7-2004. This instrument takes a single-chip microcomputer as the core, realizes all the automation of the test, high measurement accuracy, greatly improves the work efficiency, and greatly reduces the labor intensity of the staff. At the same time, the instrument has a small appearance and is easy to carry.
The ultra-low frequency tester is actually an alternative to the power frequency withstand voltage test. We know that when large-scale generators, cables and other samples are subjected to power frequency withstand voltage tests, because their insulating layers exhibit large capacitances, large-capacity test transformers or resonant transformers are required. Such huge devices are not only cumbersome and expensive, but also very inconvenient to use. In order to solve this contradiction, the electric power department adopted to reduce the test frequency, thereby reducing the capacity of the test power supply. It has been proved from many years of theory and practice at home and abroad that replacing the power frequency withstand voltage test with the 0.1Hz ultra-low frequency withstand voltage test can not only have the same equivalence, but also greatly reduce the size and weight of the equipment. It is about one-fifth of the power frequency, and the operation is simple. Compared with the power frequency test, it has more advantages. This is why this approach is commonly used in developed countries. The National Development and Reform Commission has formulated the industry standard "Ultra-low frequency (0.1Hz) withstand voltage test method for XLPE insulated power cables of 35kV and below". This method is being promoted in our country, and this instrument is developed according to the needs of our country. It can be widely used in the AC withstand voltage test of cables and large high-voltage rotating electrical machines.
We have successively established good cooperative relations with overseas customers such as Korea, Japan, Great Britain, South Africa and Kenya.
Power quality refers to the quality of the AC power supplied to the user through the public power grid. Generally speaking, it refers to the quality of the power in the power grid lines. Power quality problems are mainly caused by the terminal load side. For example, the impact reactive load will cause the grid voltage to generate Violent fluctuations reduce the quality of power supply.VIEW MORE
