Three phase operation

1. Equipped with anti bounce circuit and flexible configuration. When using the built-in anti trip circuit of the circuit breaker“TBJV+”With“HQ+”At the terminalJust short circuit it.

2.“HQ+”With“TWJ-”The“TQ+”With“HWJ-”Lead them separately to the terminals. For general circuit breakers, terminals“HQ+”With“TWJ-”After short circuiting, connect to the circuit breaker closing coil and terminal“TQ+”With“HWJ-”After short circuiting, connect to the circuit breaker to tripWire coil. For a small number of relays that are started by the outlet contact, the relay contact will restart and jump again/Circuit breakers for closing coils,And circuit breakers and devices with special operation locking circuits“TQ+”/“HQ+”Should be connected to a heavy-duty relay or a special locking circuitRoad; But“HWJ-”/“TWJ-”The terminal should still be directly connected to the circuit breaker trip coil/Close the coil to ensure correct disconnectionRoadster position.

3. jump/The current of the closing and holding circuit can automatically adapt to the rated current of the circuit breaker to prevent tripping/The closing current is less than6AThe circuit breaker canBy operation.

4. Equipped with a self-protection holding relay, it can provide a contact point after closing, which is used for starting and manual tripping when the reclosing does not correspond/When remotely tripping the circuit breaker, it is locked heavilyClose or backup automatic switching（BZT）, as well as emitting accident sounds, etc.

5. The circuit breaker provides three locking switches from the normally open contact to the operation panel: "abnormal pressure", "drop in jumping pressure", and "drop in closing pressure"And corresponding signals are generated; When the circuit breaker is abnormal and the contact is closed, the relevant tripping and closing circuit can be locked.

Voltage Parallel

1. A plug-in completes a set of voltage parallel connections, including:4A protective voltage3Measuring voltage3Test voltage, including protectionThe protective voltage adopts a double contact parallel connection method to improve the parallel reliability.

2. Voltage paralleling and uncoupling can be achieved through manual and remote control methods, and can be connected in series in the control circuit of the plugin in practical applicationsEnter the corresponding two sections of busbarPTAuxiliary normally open contacts for knife switches and section switches（1GThe2GandFDL）, as well as a multi-channel conversion handle.

Voltage switching

1. A plugin completes a set of voltage switching, including:4A protective voltage3Measuring voltage2The voltage used for the experiment. Plugin basedAccording to the accessITheIIThe normally open and normally closed contact of the mother knife switch obtains the switched voltage.

2. When it appearsIMother knife switch andIIWhen the mother knife switch is simultaneously activated or disconnected, the plugin can output "simultaneous action" or“PTLoss of pressure "The contact signal is provided for reference by operators.
