DC 220V 130 Ohm Closing and Tripping Coil

The DC 220V 130 Ohm Closing and Tripping Coil is designed for electromagnetic operation in compatible high-voltage vacuum circuit breaker mechanisms. It combines a DC220V coil, 130Ω resistance, double-ended shaft, two black multi-strand copper lead wires, brass push rod, and external reset spring. The configuration is intended for closing and opening mechanisms where the specified electrical and mechanical dimensions are matched.

Product Details

Operating Characteristics

The coil operates at DC220V with a resistance of 130Ω ±5% at 20°C. The calculated current is approximately 1.69A, with instantaneous power of approximately 372W. It is designed for short-time operation and should not remain energized continuously.

Double-Ended Shaft

The double-ended shaft provides support on both sides of the coil assembly, helping maintain balanced push rod movement and reducing deflection during operation. The brass push rod is suitable for repeated mechanical action in circuit breaker operating mechanisms.

Lead Wire Connection

The coil uses two black multi-strand copper lead wires for connection. The lead wire configuration allows flexible routing according to the wiring layout of the switchgear operating mechanism. This DC 220V 130 Ohm Closing and Tripping Coil configuration is intended for mechanisms requiring this specific shaft and connection arrangement.

External Reset Spring

The rear external reset spring provides spring self-reset after coil operation. Its external position also allows the spring condition to be checked during maintenance.

Technical Specifications

Working Principle

When DC220V is applied to the coil, current flows through the winding to generate an electromagnetic field. The magnetic force drives the brass push rod through the coil assembly, producing the mechanical movement required by the vacuum circuit breaker operating mechanism. After the control circuit cuts off the power, the external reset spring returns the push rod to its original position, preparing the mechanism for the next closing or opening operation. The DC 220V 130 Ohm Closing and Tripping Coil therefore converts the electrical control signal into the required mechanical movement.
