TBBZ high voltage reactive power automatic compensation device
Features
1.Equipped with WKG or GKWN controller, the power factor and system voltage are controlled within the set range by automatically tracking the switching capacitor and controlling the on-load voltage regulation of the main transformer.
2.Able to automatically identify and adapt to various operating modes of dual-main substations.
3.Through the remote automatic selection switch, various working modes of voltage regulation and compensation can be flexibly selected.
4.The voltage regulating switch position information can be automatically identified and displayed through BCD code or one-to-one correspondence. It has control and protection functions such as synchronous adjustment of the voltage regulating positions of two main transformers, anti-slip gear, and light gas alarm lock.
5.It can display the voltage, current, power factor, reactive power, capacitor switching status and alarm protection information on the low-voltage side of the main transformer in real time.
6.It has the function of harmonic measurement and display, which can measure and display the high-order harmonic content of low-voltage side current in real time.
7.It has alarm protection functions such as high voltage, low voltage, PT disconnection, mechanism failure, main transformer overcurrent, etc.
8.Equipped with RS-485 or RS-232 high-speed data communication interface, it can realize the "four remote" functions in conjunction with the substation integrated automation system.
9.Modular capacitor-specific high-voltage vacuum switches are used, and five units can be installed in one ordinary switch cabinet.
10.It can be flexibly grouped according to the total compensation capacity, and can be divided into 6 groups with different capacities at most. The maximum capacity of each group is 2000Kvar/5000Kvar, and it can be automatically switched according to the reactive power combination.
11.The capacitor bank is equipped with a microcomputer protection device, which can realize the two-stage overcurrent and zero-sequence voltage protection functions. When a bank fails, it can be automatically cut off and locked without affecting the normal switching of other capacitor banks.
12.Configure reactors with different ratios to limit closing inrush current and suppress high-order harmonics.
