TBBWD Low voltage reactive power dynamic compensation device

Main purpose and scope of application The
TBBWD low-voltage reactive power dynamic compensation device adopts a non-contact thyristor switch, which controls the reactive power dynamic compensation controller, tracks the change of the load reactive current, and performs fast and frequent operations on multiple groups of capacitors. Switching on and off keeps the received power factor always in the best state, thereby minimizing line loss and increasing the effective output capacity of the distribution transformer, and optimizing the quality of power consumption.
This device has obvious effects on stabilizing the system voltage, improving the power factor, and increasing the load-carrying capacity of the transformer. It is especially suitable for fast tracking and compensation of frequent and impact loads, such as frequently operated power distribution systems such as ports, building materials, petrochemicals, light industry, metallurgy, and machinery.
This product complies with: National Standard GB/T15576-2008 (our company is the main drafting unit of this standard).

Model and meaning

Working conditions
1. Altitude: ≤2000m;
2. Ambient temperature: -20℃~+45℃;
3. Relative humidity: ≤95% (at 20℃);
4. Installation environment: no flammable, explosive or serious Pollution, chemical corrosion and severe vibration;
5. Installation conditions: The harmonic content in the power grid meets the requirements of the 0.38kV clause in GB/14549.

Product features
1. The reactive power dynamic compensation of switching capacitors with non-contact thyristor switches has overall performance better than the current widely used products that use contactors for switching. It has no sparks, noise, inrush current, no overvoltage, no need to discharge capacitors, can be switched on and off quickly, and does not pollute the power grid, especially with long service life and long-term maintenance-free;
2. Average dynamic response time ≤ 10ms, the switching interval between groups is less than or equal to 20ms, any group of capacitors can be switched on immediately without discharging after being cut off;
3. Protection: short circuit, overload, overvoltage, when the voltage reaches the overvoltage protection value, the delay stops working and Exit all running capacitors group by group;
4. Automatic operation function: exit after power failure, and resume automatic operation after a delay after power on;

Ordering instructions
1. Rated working voltage, three-phase voltage and load working current fluctuation range, received power factor;
2. Load nature: stable load or shock load, whether there are large-scale rectifier equipment and medium and high frequency equipment, whether the motor is DC speed regulation Or variable frequency speed regulation;
3. Distribution variable capacity: when used as a single motor reactive power on-site compensation, provide the motor model, power, working voltage and load current variation range;
4. If the product is required to be in a severe high-order harmonic environment at work, should provide detailed harmonic situation;
5, such as the need to configure power integrated Data Please specify when ordering.
