Product Description
SK827005-DB Product Description
I. Product overview
SK827005-DB is an AC contactor product with high performance and advanced features. It may belong to the industrial automation series of ABB or other well-known manufacturers, providing stable and reliable electrical control for modern industrial fields such as power, oil, mine lifting, ports, heating, gas, water supply, sewage treatment, metallurgy, paper, textile, chemical, water conservancy, etc.
2. Main parameters and functions
Reactive sag compensation function:
The SK827005-DB is equipped with the DECS-100 system, which provides reactive sag compensation to help share reactive load during parallel generator operation.
When this feature is enabled, the DECS-100 system is able to calculate and modify voltage regulation set points to respond to generator loads with different power factors.
Sag can be adjusted up to 10% line current and 0.8 power factor at rated and nominal B-phase.
Voltage and frequency control:
At low frequencies, when the generator frequency drops below the selected inflection point frequency setpoint, the SK827005-DB automatically adjusts the voltage setpoint so that the generator voltage follows the selected PU(per unit)V/Hz curve.
The knee frequency can be adjusted from 40 Hz to 65 Hz in 0.1 Hz increments, and the slope of the PU V/Hz curve can be set from 0 to 3 (in 0.01 steps).
Protection function:
The SK827005-DB includes three protection functions: generator overvoltage, sensing voltage loss and magnetic field overvoltage.
When the generator voltage exceeds the set value or the sensing voltage is lost, the SK827005-DB is able to perform appropriate protective measures, such as turning off the relay output, disabling the DECS-100 system, etc.
Specifications and installation:
The SK827005-DB has a compact design that facilitates circuit protection in a variety of small locations.
Various specifications are available to meet different circuit protection needs.
Easy to replace contact design for easy maintenance and maintenance.
3. Application fields
SK827005-DB is widely used in power, petroleum, mine lifting, port, heating, gas, water supply, sewage treatment, metallurgy, paper making, textile, chemical industry, water conservancy and other modern industrial fields, providing stable and reliable electrical control for various automation equipment and systems.
