Abstract
The utility model relates to an energy saving type alternating current contactor applicable to the power control of an electric power system. In the alternating current contactor, on the basis of an outer casing a contactor frame, a contactor, a contact point adopted by the standard of the prior art, , an controller, a speed reduction gear, a motor, a screw shaft and a nut fixed on the contactor frame are added. The controller sends out action signals during the process of operation, the main electric circuit is caused to operate by the mechanism action composed of the parts. Because the screw shaft and the nut have the axial direction self-locking function, the alternating current contactor can stably operate if only the motor is electrified instantly. The alternating current contactor has the characteristics of energy saving, no noise and stable operating state.
Description
Affiliated technical field:
The utility model relates to a kind of power control unit of electric power system, specifically is a kind of energy-saving alternating current contactor.
Background technology:
The A.C. contactor (the national standard technological document is GB14048.4IEC60947-4-1) that generally adopts is to adopt to give coil electricity at present, electromagnetic actuation, charged maintenance, the mode work that outage discharges, it exists can be high, produce electromagnetic noise, the defective of job insecurity when the circuit operating voltage fluctuates.
Summary of the invention:
For overcoming existing A.C. contactor energy consumption height, the deficiency of aspects such as generation electromagnetic noise, the utility model provides a kind of energy-saving alternating current contactor, it not only can solve former contactor energy consumption height, produce the problem of electromagnetic noise, and still can operate as normal when the working line scope range of the fluctuation of voltage is big.
The scheme that its technical problem that solves the utility model adopts is: under the constant substantially situation of the A.C. contactor shell, contact, contact, the contact frame that keep existing original technology, remove original electromagnet, coil, nut is fixed on the contact frame, and the position of nut is the axis of this contactor; The screw shaft that motor, reduction gearing and upper part is had the certain-length screw thread is fixed on the base of contactor, and the position of screw rod is the axis of this contactor; Motor and screw shaft mesh by reduction gearing, and screw rod and contact frame mesh by nut; Controller is connected by lead with motor.When controller sends the rotating signal to motor, motor rotates by reduction gearing screw shaft is rotated, and then makes the reciprocating action of contact frame by the transmission of nut, simultaneously, be positioned at the contact on the contact frame, disconnect the closed purpose that reaches control main circuit break-make with the contact that is positioned on the shell.When the circuit power failure, when restoring electricity, controller sends reset signal automatically, and motor action is cut off main circuit according to above-mentioned transmission process.Because the self-locking action of the axle of screw shaft and nut,, contact and contact disconnect or during the dead-centre position of closure, entire mechanism forms stable operating state the motor work of no longer switching on when reaching.Regulate according to the gap of contact and contact the conduction time of the length of screw thread and motor on the screw shaft.
The beneficial effects of the utility model are: because motor is instantaneous energising work, and adopt machinery to keep the no longer power consumption of main circuit duration of work motor.Its use has reached effect energy-conservation, noise reduction.
Description of drawings:
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a vertical section of the present utility model structural map.
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is the controller circuitry functional-block diagram.
1. controllers among the figure, 2. base, 3. motor, 4. reduction gearing, 5. screw shaft, 6. nut, 7. contact frame, 8. contact, 9. contact, 10. shell.
Embodiment:
Motor in Fig. 1 (3) meshes together by reduction gearing (4) with screw shaft (5), and screw shaft (5) is positioned on the axis of this contactor, and motor (3), reduction gearing (4), screw shaft (5) are fixed in base (2) and go up and use Plastic Package; Nut (6) is fixed on the contact frame (7), and screw shaft (5) links to each other with contact frame (7) by nut (6) engagement; The length that screw shaft (5) is gone up screw thread is determined by the contact gap between contact (8) and contact (9).
Contact in Fig. 2 (8) is fixed on the contact frame (7), and contact (9) are fixed on the shell (10), and the action of contact (8) and contact (9) makes the main circuit break-make.
Link by lead between motor (3) and the controller (1).
Contact frame (7), contact (8), contact (9) shell (10) are original technical standard.
Its course of action is: controller (1) sends the rotating signal to motor (3), motor (3) rotates by reduction gearing (4) engagement screw shaft (5) is rotated, and then contact frame (7) reciprocating action at drive nut (6) place, be positioned at the contact (8) on the contact frame, disconnect closure with the contact (9) that is positioned on the shell (10), reach the purpose of control main circuit break-make.
Claims (2)
1, a kind of energy-saving alternating current contactor that is made of shell, contact frame, contact, contact is characterized in that it contains motor, travelling gear, screw shaft and be fixed in the nut of spindle nose frame.
2, according to the described energy-saving alternating current contactor of claim 1, its feature also is: screw shaft and nut that the upper end has the certain-length screw thread all are positioned on the axis of contactor; Screw shaft, reduction gearing, motor are fixed on the base, and motor and screw shaft mesh by reduction gearing; Nut is fixed on the contact frame, and screw shaft and contact frame mesh by nut.
