The microcomputer relay protection test set, contact phone 17306297777, is a new type of intelligent test instrument developed in the past decade. Previous relay protection test tools mainly consisted of voltage regulators and phase shifters, which were bulky, heavy, and had low accuracy, unable to meet the calibration requirements of modern microcomputer relay protection. With the continuous development of science and technology, microcomputer relay protection has been widely applied in various fields such as line protection, main transformer differential protection, and excitation control. Substation comprehensive automation has become the mainstream. Therefore, the microcomputer relay protection test set will inevitably become an indispensable test tool for modern relay protection workers.
Modern microcomputer relay protection test sets can be divided into two types. One type uses traditional OCL power amplifiers, which are large in size, weigh about 25 kg, and are relatively bulky. The power amplifier tubes operate in the amplification region and are prone to damage over time, with a narrow dynamic range and low accuracy. The other type uses switching power supplies and digital power amplifiers, which are small in size, light in weight, and highly efficient, representing the development direction of relay protection test sets. The TH-2000 relay protection test set is a new type of miniaturized microcomputer relay protection test set developed by summarizing the advantages and disadvantages of similar products at home and abroad, extensively listening to user opinions, and fully applying modern microelectronics and power electronics technology. It adopts internationally popular DSP and switching amplifier technology. Its standalone operation capability is already very powerful, and when combined with PC software, it can be connected to a computer for operation, adding even more functionality. Its size and weight are only half of traditional test sets, and its advanced design concept brings this test set to a leading level.
Main Features
1.Meets all on-site test requirements. It has standard six-phase current and six-phase voltage simultaneous output, with current30A/phase, voltage 125V/phase.
