SecoVac 3.3kV-27kV Embedded Pole Vacuum Circuit Breaker
Working Principle Vacuum interrupter The vacuum gas pressure inside vacuum interrupter is less than 1.33×10-3Pa. Under normal circuit conditions the interrupter is closed. Arcing is established within the interrupter by withdrawing the moving contact from stationary contact. This arc burns in the metal vapor evaporated from local hot spots on the contact surfaces. The metal vapor continually leaves the inter-contact region and recondenses on the contact surfaces and surrounding metal vapor condensation shield. The latter is usually isolated from both contacts and serves to protect the glass or ceramic envelope from vapor deposition. At current zero, vapor production ceases and the original vacuum condition is rapidly approached. The dielectric strength of the interrupter also increases, and the circuit is interrupted. Within the contacts in the open position, the circuit voltage is withstood internally by the inter-contact gap
Operation
and externally by the insulating envelope.
Working Principle of Operating Mechanism Spring motor spring charging 1
The energy that is necessary for closing the circuit breaker is provided by the closing spring. The energy storage can be done by the motor or by the manual charging handle. Motor spring charging The energy charging mechanism consists of energy storing motor, gear wheel, cam, holder and closing spring. When the energy-storing motor (11) is charged, the pinion of output shaft (12) that is connected to motor will rotateand drive the gear wheel. The holder fixed on the gear wheel will make the cam fixed on the shaft move, which then drive the shaft to rotate, so that draws out the closing spring (17) for storing energy. When the block on the gear wheel is pushed away, the clutch is separated and the holder (4) will hold the roller on the cam (5) to keep the mechanism in charged position, thus completing the charging operation succeeds.

When energy is charged manually, the operator charges the spring by operating the energy-charging handle on the mechanism up and down repeatedly. When the charging operation is completed, you can hear a 'click', and the energy charging indicator (13) is switched over, as well as the status of position switch (6), cutting the secondary charging circuit. The operating mechanism now is ready for the next operation. (Figure 3)

to push the roller on the main shaft, which will move the main connecting rod down through arm, so that the insulating rod (2) moves upright, pushing the movable contact to the fixed contact at the required speed, and compressing the contact spring and making it a necessary contact travel (overtravel) to ensure the pressure is generated between movable and fixed contacts.
Reclosing When the circuit breaker is closed, the mechanism can be charged for close, so that the circuit breaker can reclose immediately after tripping.
After the closed operation is finished, the closed/opening indicator (9) will indicate 'closed'. The power to the closing circuit will be cut. If the external power supply is energized, the charging

circuit motor will operate and the charging operation will be finished automatically. Note: Once the circuit breaker is in closed position, the closing operation will be prohibited.
Tripping operation When the breaker receives an opening command (the opening push button is pressed or the tripping coil (16) is energized), the tripping shaft will rotate clockwise. Under the action of opening spring (3) and contact-compressing spring, main shaft will move clockwise, and the insulating rod (2) will make the movable contact to separate from the fixed contact at a suitable speed. The buffer will absorb the residual energy and tripping operation is completed. After the tripping operation is finished, the closing/opening indicator (9) will indicate 'open'. Meanwhile, the counter will record the operation.
