In the low-voltage power system with a rated current of 120A and a total capacity of the capacitor bank less than 50 kvar, the combined use advocated by Geyue Electric of GYFK-120A 220V 50Kvar Split-Phase Compensation Three Phase Intelligent Low Voltage Compound Switch and automatic compensation controller is the key to achieving efficient and accurate reactive power compensation. The following is a detailed description of their combination mode and working principle:
1. System Composition.
Generally speaking, a Geyue Electric low-voltage power compensation system is composed of three basic components: capacitor banks, automatic compensation controllers and GYFK-120A 220V 50Kvar Split-Phase Compensation Three Phase Intelligent Low Voltage Compound Switches.
Capacitor bank: Provides reactive power compensation and is usually divided into multiple groups, with each group having a smaller capacity for convenient stepwise switching.
Automatic compensation controller: Monitors parameters such as voltage, current, and power factor of the system in real time. Controls the GYFK-120A 220V 50Kvar Split-Phase Compensation Three Phase Intelligent Low Voltage Compound Switches to switch capacitors according to the reactive power demand.
GYFK-120A 220V 50Kvar Split-Phase Compensation Three Phase Intelligent Low Voltage Compound Switch: Responsible for the non-surge switching of each phase capacitor and supports split-phase compensation. It has protection functions such as overvoltage, undervoltage, phase loss, and over-temperature.
Other components: Miniature circuit breakers (such as DZ47) provide overload and short-circuit protection for each phase capacitor branch. Current transformers (CT) are used to collect the system current signal for the controller.
2. Combination Mode
Connection between the controller and the compound switch: The automatic compensation controller is connected to the GYFK-120A 220V 50Kvar Split-Phase Compensation Three Phase Intelligent Low Voltage Compound Switch through the control line (usually a low-voltage signal line). The controller sends switching instructions to the GYFK-120A 220V 50Kvar Split-Phase Compensation Three Phase Intelligent Low Voltage Compound Switch based on the real-time monitored data.
Grouping of capacitor banks: The capacitor banks are divided into multiple groups by capacity (such as 5 kvar, 10 kvar, 15 kvar, etc.), and each group corresponds to a compound switch. The capacitor banks of each phase are independently configured to achieve split-phase compensation.
Configuration of protection devices: Install miniature circuit breakers (such as DZ47) on each phase capacitor branch to provide overload and short-circuit protection. Current transformers (CT) are installed in the main circuit to collect the system current signal.
3. Working Principle
Working principle real-time monitoring: The automatic compensation controller monitors parameters such as voltage, current, and power factor of the system in real time through current transformers (CT) and voltage signals.
Reactive power demand calculation: The controller calculates the reactive power demand of the system based on the monitored data and determines the capacitor capacity that needs to be put in or cut off.
Phase-by-phase compensation control: The controller sends switching instructions to the corresponding GYFK-120A 220V 50Kvar Split-Phase Compensation Three Phase Intelligent Low Voltage Compound Switches respectively, according to the reactive power demand of each phase. The compound switch switches ON or switch OFF the capacitor at the zero crossing of voltage or current to achieve non-surge switching.
Protection function: The GYFK-120A 220V 50Kvar Split-Phase Compensation Three Phase Intelligent Low Voltage Compound Switch and the miniature circuit breaker jointly provide protection such as overload, short circuit, overvoltage, and undervoltage to ensure the safe operation of the system.
Dynamic adjustment: The controller dynamically adjusts the switching status of the capacitors according to the changes in the system load to ensure that the power factor is always maintained within the set range.
