The Medium voltage automatic reactive power compensation complete device Designed for use in 50Hz AC power systems with a voltage of up to 35kV, substations installed on the 6-35kV side feature a power factor, improving voltage quality and reducing network losses. There are two types of structures available for the high voltage automatic reactive power compensation equipment. One type is cabinet-based, offering features such as electromagnetic locking and a live display function, with the option to include reactive automatic controllers and automatic switching based on specific needs. These cabinets are highly integrated and tightly structured for indoor use. The other type is frame-based, cost-effective, and requires users to provide electromagnetic closure.
This Medium voltage automatic reactive power compensation complete device is suited for outdoor use and is mainly intended for the installation of high-voltage parallel capacitor structures, ensuring compliance with switchgear regulations. The equipment is designed for a seamless "turnkey" process, including design innovation, installation, and commissioning. Primarily catering to small transformer substations and commercial users, the capacitor devices are installed indoors for optimal performance..
The device is primarily utilized in power systems with a voltage of 35kV or lower. It automatically regulates the switching of capacitor banks on 35kV and lower buses to comprehensively control substation voltage and reactive power. This results in improved power factor, reduced transformer and line losses, and enhanced power supply voltage quality.
The device's user-friendly design makes it adaptable for use in various industries, including metallurgy, mining, building materials, petroleum, chemical production, and municipal three-phase AC power systems. It is responsible for field installation and debugging, taking into account harmonic issues, and can be designed with a series reactance rate of 4.5% or higher for effective harmonic governance.
In addition, the device can be employed in large rural power grid substations to maximize reactive power compensation, considering the daily and seasonal variations in substation load. It can also be used in unattended urban network substations, offering the convenience of "four remote" functionality.
Furthermore, the device can be utilized to transform old substation capacitor devices, enhancing the level of automation and operational efficiency in substations..
