Abstract
The invention provides an under-voltage tripping device for permanent magnetic actuator circuit breakers. The principle is as follows: a control power supply U stores energy for an electrolytic capacitor C through a current limiting resistor R1; the size of the electrolytic capacitor C is determined by the magnitude of electromagnetic field energy needed for action of a permanent magnetic actuator YR; when the control power supply U is too low or cut off, diodes D1-D3 in an energy storage circuit stop the electrolytic capacitor C from supplying power to a control circuit reversely; a voltage relay KA of which the coil voltage can be set is adopted to detect the level of the control power supply U; when the level of the control power supply U is lower than a set value, the voltage relay KA is switched on, a normally open contact quickly cuts off an external power supply circuit to prevent the energy storage capacitor C from supplying power to the control circuit reversely, a normally closed contact is delayed to enable the permanent magnetic actuator YR to be electrified and generate an electromagnetic field to switch off a vacuum circuit breaker, and the voltage relay KA is delayed to prevent false switching-off operation caused by short-term fluctuation of the control power supply. By adopting the under-voltage tripping device of the invention, the problem on how to reliably switch off a permanent magnetic circuit breaker when there is no operating power supply outside can be solved effectively.
