Abstract
The utility model relates to a high-voltage vacuum circuit breaker of a permanent magnet control mechanism, which comprises a rectifying device, an energy storage capacitor, a permanent magnet coil and a permanent magnet coil control device. The high-voltage vacuum circuit breaker is characterized in that a UPS power supply is connected with an inlet wire terminal of the rectifying device in parallel. The utility model has the advantage that the small UPS power supply is added in the vacuum circuit breaker, so that when an external power system is power-down, the UPS power supply can continue to serve as a switch on/off power supply and a control power supply. The additional UPS power supply can enable the vacuum circuit breaker to conduct dozens of times of switch on/off operations when the external power supply is power-down.
Description
Technical field
The utility model relates to a kind of high-pressure vacuum breaker of permanent-magnet manipulating mechanism.
Background technology
Existing permanent magnetism vacuum circuit-breaker, the required direct current of its divide-shut brake are by after the rectification of AC power process rectifying device, are stored in the capacitor.Behind power cut-off, energy stored is only enough done a divide-shut brake and is used standby for a long time in the capacitor.
Summary of the invention
The purpose of this utility model provides the vacuum circuit-breaker that standby for a long time after a kind of outage also can be carried out the long stand-by time of tens breaking-closing operatings.
The utility model is achieved through the following technical solutions:
A kind of vacuum circuit-breaker of growing stand-by time, comprise rectifying device, storage capacitor, permanent magnetism coil, permanent magnetism coil control device, it is characterized in that, at the power inleting terminal of rectifying device and be connected with ups power, changing the time also and be connected with permanent magnetism coil control device simultaneously, the permanent magnetism coil control device other end is connected with the permanent magnetism coil; The output of rectifying device is connected to the permanent magnetism coil, is parallel with storage capacitor between rectifying device and permanent magnetism coil.
The utility model has the advantages that: in vacuum circuit-breaker, add a small-sized ups power, in case after the power down of external power source system, continue to provide divide-shut brake power supply and control power supply to vacuum circuit-breaker by ups power.After adding ups power, after the external power source power down, vacuum circuit-breaker still can carry out tens times breaking-closing operating.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
See Fig. 1, a kind of vacuum circuit-breaker of growing stand-by time, comprise rectifying device, ups power, storage capacitor, permanent magnetism coil, permanent magnetism coil control device, ups power is connected in the power inleting terminal of rectifying device, changing the time also and be connected with permanent magnetism coil control device simultaneously, the permanent magnetism coil control device other end is connected with the permanent magnetism coil; The output of rectifying device is connected to the permanent magnetism coil, is parallel with storage capacitor between rectifying device and permanent magnetism coil.In vacuum circuit-breaker, add ups power, in case after the power down of external power source system, can continue to provide divide-shut brake power supply and control power supply to vacuum circuit-breaker by ups power.
