Description
Technical field
The utility model relates to power supply unit in electric power system, specifically a kind of intelligentized high-tension switch cabinet earthed switch electrically operated device.
Background technology
That builds along with national intelligent grid pushes forward comprehensively; it is intelligent that electrical network not only requires that to the various switchgears in electric power system the aspects such as monitoring and protection realize; but also require that the operation of switchgear also can realize intellectuality; and the disjunction of earthed switch is grid maintenance and stoppage in transit requisite safety assurance when safeguarding; therefore, in intelligentized high-tension switch cabinet, accurate, reliable earthing switch electrical operating mechanism is also necessary.
Summary of the invention
Order of the present utility model has exactly in order to overcome the deficiencies in the prior art, provides a kind of conjunction that is safe and reliable, earthed switch and divides operation to realize intelligentized high-tension switch cabinet earthed switch electrically operated device.
The utility model can be reached by following measure:
A kind of high-tension switch cabinet earthed switch electrically operated device, comprise DC motor and gear box, it is characterized in that DC motor is connected with gearbox input shaft through ball-type snap-on connector, gearbox output shaft is connected with one end of action bars, gearbox output shaft and action bars are vertical configuration, the other end of action bars is connected with earthed switch lever, and DC motor via controller is connected with DC power supply.
Action bars described in the utility model is connected through bearing pin with earthed switch lever, and the action bars under bearing pin or earthed switch lever are provided with sensitive switch, and sensitive switch is electrically connected with DC motor, realizes intelligent operation.
Action bars under bearing pin described in the utility model or earthed switch lever are provided with groove, are provided with sensitive switch in groove, and the corresponding earthed switch lever in contact of sensitive switch or action bars are provided with shake-up boss.
When the utility model uses, gearbox and DC motor are arranged on the cabinet of earthed switch in high-tension switch cabinet, when receiving reclosing command, DC motor drives action bars inwardly to swing through gearbox, and action bars drives earthed switch lever to carry out feed motion, when closing a floodgate, touch the contact of boss pressure sensitive switch, DC motor current supply circuit is cut off, and DC motor is out of service, namely completes feed motion; When receiving separating brake instruction, DC motor drives action bars outwards to rotate through gear box, action bars drives earthed switch lever to carry out separating brake action, when separating brake, the contact of touching boss and sensitive switch is separated, and DC motor current supply circuit is cut off, motor is out of service, namely separating brake action is completed, its advantageous effect: one is substitute manual operation completely, has ensured personal safety; Two is meet electrical network intelligent streamlining, convenient switchgear upgrading in the future; Two is make a point closing operation for earthed switch become more precisely reliable, effectively avoids misoperation.
Accompanying drawing explanation
