The microcomputer harmonic elimination device is a new intelligent power resonance elimination device developed by our company. It is easy to use, without maintenance, and can quickly eliminate the ferromagnetic resonance of various frequencies with high accuracy. At the same time, it can print the relevant information according to the user's needs or upload it to the superior monitoring system through the communication interface. It is suitable for unattended substation.
The micro-computer harmonic elimination device circularly detects the open triangle voltage. Under normal working conditions, the voltage is less than 30V, and the high-power harmonic elimination element (SCR) in the device is in the blocking state, which has no effect on the system. When the opening triangle voltage of the voltage transformer is greater than 30V, it indicates that the system is faulty.
The primary harmonic elimination device and the microcomputer harmonic elimination device not only have different wiring mode, but also can play a complementary role in the normal operation of the power grid. The microcomputer harmonic elimination device is installed in the terminal box. According to the user's selection, each device can be connected to 1 ~ 4 sections of bus.
As we all know, bus is a product with the ability of collecting and distributing electric power. In power station, it is the main wire used to transmit electric energy. Through it, the output electric energy of generator, transformer or rectifier is transmitted to each user or other substation. The commonly used microcomputer harmonic elimination devices in the market are equipped with 1, 2 and 4 sections of buses respectively. The reason why there are few intelligent microcomputer harmonic elimination devices with 3 sections of buses is that there are few 3 sections of buses in power stations. Domestic power systems commonly build 1, 2 and 4 sections of buses. As a professional manufacturer of microcomputer harmonic elimination devices, the 3 sections of buses can be customized according to the actual situation of users.
