DK-1 type control box using the AC electromagnet closing circuit

The DW15-200-630A breaker solenoid is a DC solenoid designed for short-time operation. The DK-1 control box utilizes an AC power switch to manage the electromagnet circuit, as depicted in Figure 6-7. The DK-1 type electromagnetic control box includes several components: SBi serves as the closing button, SBz functions as the opening button, YA is the closing solenoid coil, YR is the trip coil, KA is the intermediate relay, QF represents the circuit breaker auxiliary contacts, and Ri to R4 are resistors, while Ci and C2 act as storage capacitors.

The DW15-200-630A breaker solenoid is integral to the operation of circuit protection systems, specifically designed to engage and disengage electrical circuits under controlled conditions. The solenoid operates on direct current (DC) and is intended for short-duration applications, making it suitable for environments where rapid actuation is necessary.

The DK-1 control box plays a crucial role in managing the solenoid's operation. The inclusion of an AC power switch allows for the energization of the electromagnet circuit, which is essential for the solenoid's functionality. The control box is equipped with a closing button (SBi) and an opening button (SBz) that provide manual control for the solenoid's operation. When the closing button is pressed, the solenoid coil (YA) is energized, causing the solenoid to actuate and close the circuit. Conversely, pressing the opening button (SBz) deactivates the solenoid, allowing the circuit to open.

The trip coil (YR) is an important safety feature that enables the circuit to be opened automatically under fault conditions. The intermediate relay (KA) serves to amplify the control signals, ensuring reliable operation of the solenoid and enhancing the overall responsiveness of the circuit protection system.

In addition to these primary components, the control box includes resistors (Ri to R4) that are used for current limiting and voltage division, ensuring that the circuit operates within safe parameters. The storage capacitors (Ci and C2) are critical for smoothing out voltage fluctuations and providing stable operation of the solenoid, particularly during rapid switching events.

Overall, the DW15-200-630A breaker solenoid and its associated DK-1 control box represent a robust solution for electrical circuit control, combining manual and automatic features to enhance operational safety and reliability.DW15-200-630A breaker solenoid DC solenoid structure, short-time working.
