AC-DC Superposition Output Voltage and Current Stabilization Control Method for Capacitor Ripple Test Power Supply

Abstract

The present invention discloses a method for stabilizing voltage and current control of AC-DC superposition output of a capacitor ripple test power supply, belonging to the technical field of voltage and current stabilizing control methods. The user inserts an adjustment plug into a power socket, and clamps the outside of the adjustment plug through a lifting clamping assembly. When a short circuit occurs, the high temperature causes the C-type thermosensitive conductive clamping piece to deform outwards, thereby expanding the inner diameter of the C-type thermosensitive conductive clamping piece, so that the C-type thermosensitive conductive clamping piece releases the clamping of the elastic reset rod part. Under the action of elastic force, the elastic reset rod part quickly resets, so that the C-type thermosensitive conductive clamping piece slides outside the elastic reset rod part to cut off the power supply. Synchronously, the movement of the elastic reset rod part drives the linkage wire wheel part to rotate quickly to pull the guide rope, and the guide rope pulls the lifting clamping assembly through the guide wheel assembly to pull out the adjustment plug, releasing the contact between the power socket and the adjustment plug.

[0041] To make the technical solutions of the present invention clearer and more definite for those skilled in the art, the present invention will be further described in detail below in conjunction with embodiments and the accompanying drawings. However, the implementation manners of the present invention are not limited thereto.

[0042] As Figures 1-11As shown, the capacitor ripple test power supply AC / DC superposition output voltage and current stabilization control method provided in this embodiment includes a controller for the voltage and current stabilization control method, the controller includes a housing 1, the housing 1 has a circuit board 9 built in, an elastic reset rod portion is installed at the inner tail of the housing 1 through an L-shaped fixing plate 29, and the inner tail of the housing 1 is also provided with a linkage wire wheel portion through a C-shaped fixing plate 12, and the linkage wire wheel portion is slidably matched with the elastic reset rod portion;

[0043] A C-shaped thermal conductive positioning piece 37 is installed on the C-shaped fixing plate 12, which is sleeved on the elastic reset rod and thermally limits the elastic reset rod. A power socket 13, a guide wheel assembly and a lifting clamping assembly are installed through the tail of the housing 1.

[0044] The lifting clamping assembly clamps the adjustment plug 14 inserted into the power socket 13, and the adjustment plug 14 is pulled out by adjusting the lifting clamping assembly through the guide wheel assembly;

[0045] The inner head of the housing 1 is provided with a retractable wheel portion, which is hinged with a side clamping seat portion.

[0046] The overall working principle is as follows: the user inserts the adjustment plug 14 into the power socket 13, and clamps the outer side of the adjustment plug 14 through the lifting clamping assembly. When a short circuit occurs, the high temperature causes the C-type thermal conductive clamping piece 37 to deform outward, thereby expanding the inner diameter of the C-type thermal conductive clamping piece 37, so that the C-type thermal conductive clamping piece 37 releases the clamping of the elastic reset rod. Under the action of the elastic force, the elastic reset rod is quickly reset, so that the C-type thermal conductive clamping piece 37 slides on the outer side of the elastic reset rod to cut off the power supply. The movement of the elastic reset rod drives the linkage wire wheel part to rotate quickly to pull the guide rope 24, and the guide rope 24 pulls the lifting clamping assembly through the guide wheel assembly. Pull out the adjustment plug 14 to release the contact between the power socket 13 and the adjustment plug 14, thereby realizing the double power-off function. When the short-circuit problem is solved and the C-type thermistor conductive positioning piece 37 is cooled and reset, pull the elastic reset rod to make the C-type thermistor conductive positioning piece 37 snap into the elastic reset rod again, thereby pulling the lifting clamping assembly to reset, and driving the adjustment plug 14 to be inserted into the power socket 13 again for power supply, insert the shell 1 into the opened door panel of the electric cabinet, move the shell 1 to align the opened door panel opening with the side clamping seat, start the retractable wheel to adjust the side clamping seat to expose the side of the door panel opening to clamp the shell 1, so that the shell 1 is fixed on the door panel opening, so it is also very convenient to disassemble.

[0047] In this embodiment, the elastic reset rod portion includes an insulating reset rod 2, a pull ring 3, an inner spring reset cylinder 30 and a conductive inner column 38;

[0048] On one side of the L-shaped fixing plate 29, an inner spring return cylinder 30 is installed, and a conductive inner column 38 is installed at the output end of the inner spring return cylinder 30. One end of the conductive inner column 38 away from the inner spring return cylinder 30 is installed with an insulating return rod 2, and a pull ring 3 is installed at the end of the insulating return rod 2.

[0049] Local working principle: When the user pulls the pull ring 3, it drives the insulating return rod 2 to move. Since the inner spring return cylinder 30 is connected to the insulating return rod 2 and there is a high-strength spring inside the inner spring return cylinder 30, it can achieve the function of rapid reset, and the insulating return rod 2 can slide along the axial direction of the inner spring return cylinder 30 when the pull ring 3 is pulled.

[0050] In this embodiment, the linkage wire wheel part includes a linkage gear 33, a rack 10, a side rotating rod 32, a wire guiding disc 34, and a wire guiding column 35;

[0051] At the inner tail of the housing 1, a C-shaped fixing plate 12 is installed. On one side of the C-shaped fixing plate 12, a side rotating rod 32 is installed through a bearing. The outer side of the side rotating rod 32 is installed with a linkage gear 33, and wire guiding discs 34 are sleeved above and below the outer side of the linkage gear 33. A wire guiding column 35 is installed inside the C-shaped fixing plate 12. On the side of the insulating return rod 2 facing the linkage gear 33, a rack 10 is provided, and the rack 10 meshes with the linkage gear 33. The wire 24 is wound around the outer side of the wire guiding disc 34 and passes through the wire guiding column 35.

[0052] Local working principle: The movement of the insulating return rod 2 synchronously drives the movement of the rack 10. Since the rack 10 meshes with the linkage gear 33, the rack 10 adjusts the rotation of the linkage gear 33. Through the linkage gear 33, the wire 24 is pulled to move. The wire 24 is wound around the outer side of the wire guiding disc 34 and passes through the wire guiding column 35.

[0053] In this embodiment, the wire guiding wheel assembly includes a second guiding wheel 22 and a first guiding wheel 21;

[0054] At the tail of the housing 1, a second guiding wheel 22 and a first guiding wheel 21 are installed, and a wire guiding hole 23 is opened at the tail of the housing 1. The wire 24 passes through the wire guiding hole 23, passes through the bottom of the second guiding wheel 22, and is connected to the lifting and clamping assembly through the upper side of the first guiding wheel 21.

[0055] Local working principle: The wire 24 is guided by passing through the second guiding wheel 22 and the first guiding wheel 21 to achieve the function of guiding the wire 24 and pulling the lifting and clamping assembly.

[0056] In this embodiment, the lifting and clamping assembly includes a limit support sliding rod 19, a sliding piece 20, a spring fixing plate 17, a return spring 18, a lifting and clamping seat 16, a clamping strip 15, an inner limit sliding rod 31, and an inner clamping spring 11;

[0057] A limiting support sliding rod 19 is installed at the tail of the housing 1, and a spring fixing plate 17 is installed at the end of the limiting support sliding rod 19. A sliding piece 20 is sleeved outside the limiting support sliding rod 19. A return spring 18 is installed between the sliding piece 20 and the spring fixing plate 17. An elevating clamping seat 16 is installed on one side of the sliding piece 20. An inner limiting sliding rod 31 is installed inside the elevating clamping seat 16. Two groups of clamping strips 15 are sleeved outside the inner limiting sliding rod 31. An inner clamping spring 11 is installed between the two groups of clamping strips 15. The inner clamping spring 11 is sleeved outside the inner limiting sliding rod 31. The end of the guide rope 24 is connected to the outside of the sliding piece 20.

[0058] Local working principle: By pulling the clamping strip 15, the adjusting plug 14 is clamped between the two groups of clamping strips 15. By pulling the guide rope 24, a pulling force is generated on the sliding piece 20, so that the sliding piece 20 slides outside the limiting support sliding rod 19, thereby driving the elevating clamping seat 16 to pull out the clamping strip 15 from the power socket 13. Therefore, the function of quickly separating the adjusting plug 14 from the power socket 13 is realized.

[0059] In this embodiment, the winding and unwinding wheel part includes a winding and unwinding motor, an end fixing plate 25, a hinged connecting rod 27, an adjusting disc 28 and a limiting sleeve 26;

[0060] An end fixing plate 25 is installed at the inner end of the housing 1. An adjusting disc 28 is installed in the middle of the end fixing plate 25 through the winding and unwinding motor. A hinged connecting rod 27 is hinged to the outer side edge of the adjusting disc 28. A limiting sleeve 26 is integrally formed on one side of the end fixing plate 25. The hinged connecting rod 27 passes through the limiting sleeve 26 and is hinged to the side clamping seat part.

[0061] Local working principle: By starting the winding and unwinding motor to drive the adjusting disc 28 to rotate, the hinged connecting rod 27 is adjusted to move through the adjusting disc 28, and the limiting sleeve 26 is used to position the hinged connecting rod 27 to prevent the hinged connecting rod 27 from rotating excessively. By the movement of the hinged connecting rod 27, the movement of the side clamping seat part is adjusted to realize the function of pushing the side clamping seat part to clamp the side part of the door panel opening.

[0062] In this embodiment, the side clamping seat part includes a C-shaped clamping member 8 and a side groove 7. Side grooves 7 are opened on both sides of the end of the housing 1. The C-shaped clamping member 8 is inserted into the inner side of the side groove 7. The C-shaped clamping member 8 is hinged to the end of the hinged connecting rod 27.

[0063] Local working principle: By the movement of the hinged connecting rod 27, the C-shaped clamping member 8 is adjusted to move inside the side groove 7 to realize that the C-shaped clamping member 8 extends out of the side groove 7 to clamp the side part of the door panel opening.
