DGAC Low-Voltage Static Type Reactive In-Situ Compensation Device
Application
The DGAC series of devices are introduced the micro-computer control program by the computer aided Design(CAD)so as to trace and compensate the reactive electricity intelligently. With the reasonable construction and advanced techniques, these devices are widely applied to low voltage electric network to promote power factor, reduce reactive loss, and improve the quality of power supply, therefore they are the energy saving products of the new generation.
Model and implication
Main Characteristics
Small size facilitates installation and maintenance of equipment. It is designed specially for reactive local compensation of three-phase transformers with rated voltage 380V and capacity 30~600KVA.
Controlled by microcomputer and adopting automatic compensation mode, it has complete functions and reliable performance. LED digital display shows the power factor of power line, ranging from lagging (0.00~0.99) to leadign(0.00~0.99).
The set values of COSΦ, delay and over-voltage can be set through three functional set keys on the panel keyboard and shown on the digital display. Concise man-machine dialogue facilitates the operation.
With pilot lamp indicating the lagging, leading to operate and over-voltage, LED hints program input.
With over-voltage protection function, it is safe in operation. (The over-voltage set value has been set at 430V in factory. The user can reset is between 400V and 450V according to their own needs.) When power line voltage exceeds the set value, COSφ digital meter is changed automatically and shows the present voltage value of power line. At the step by step. Once the voltage regains normally, This installation will work automatically again.
Having strong anti jamming capability, it can resist nterference pulse of 2000V input directly through power line. The index exceeds national special standard.
