However, existing voltage regulators use thermally fused resistors to quickly cut off power in case of a short circuit. This design does not effectively achieve the function of adjustment and reset after power failure, and the fuse method is not convenient for maintenance.

[0022] Step 1: The user inserts the adjustment plug into the power socket and uses the lifting clamping assembly to clamp the outside of the adjustment plug;

[0023] Step 2: When a short circuit occurs, the high temperature causes the C-type thermal conductive locking piece to deform outward, expanding the inner diameter of the C-type thermal conductive locking piece, thus releasing the C-type thermal conductive locking piece from locking the elastic reset rod.

[0024] Step 3: Under the action of elastic force, the elastic reset rod quickly resets, causing the C-type thermal conductive locking piece to slide on the outside of the elastic reset rod to cut off the power. Simultaneously, the movement of the elastic reset rod drives the linkage guide wheel to rotate quickly and pull the guide rope.

[0027] Beneficial technical effects of the present invention:

[0028] The present invention provides a method for controlling the AC / DC superimposed output voltage and current regulation of a capacitor ripple test power supply. The user inserts an adjustment plug into a power socket and clamps the plug using a lifting clamping assembly. When a short circuit occurs, high temperature causes the C-type thermistor conductive locking piece to deform outward, thus expanding its inner diameter. This releases the C-type thermistor conductive locking piece from the elastic reset rod. Under the action of elastic force, the elastic reset rod quickly resets, causing the C-type thermistor conductive locking piece to slide outside the elastic reset rod to cut off the power. Simultaneously, the movement of the elastic reset rod drives the linkage guide wheel to rotate rapidly, pulling the guide rope. The guide rope passes through... The guide wheel assembly pulls the lifting clamping assembly to remove the adjustment plug, disconnecting the power socket from the adjustment plug and achieving a double power-off function. After the short circuit problem is resolved, the C-type thermal conductive locking piece also cools down and resets. Pulling the elastic reset rod makes the C-type thermal conductive locking piece snap back into the elastic reset rod, thereby pulling the lifting clamping assembly to reset and causing the adjustment plug to be inserted back into the power socket for power supply. Insert the housing into the opened cabinet door panel, move the housing until the opened door panel opening is aligned with the side clamping seat, and activate the retractable wheel assembly to adjust the side clamping seat to expose the side of the door panel opening for clamping, thus fixing the housing to the door panel opening. Therefore, disassembly is also very convenient. Attached Figure Description

[0041] To enable those skilled in the art to understand the technical solution of the present invention more clearly, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0042] like Figures 1-11As shown, the capacitor ripple test power supply AC / DC superimposed output voltage and current regulation control method provided in this embodiment includes a controller for voltage and current regulation control method. The controller includes a housing 1, a circuit board 9 is built into the housing 1, an elastic reset rod is installed at the inner tail of the housing 1 by an L-shaped fixing plate 29, and a linkage guide wheel is also provided at the inner tail of the housing 1 by a C-shaped fixing plate 12. The linkage guide wheel slides in cooperation with the elastic reset rod.

[0043] A C-shaped thermal conductive locking 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 holds the adjustment plug 14 inserted into the power socket 13, and the lifting clamping assembly is adjusted by the guide wheel assembly to pull out the adjustment plug 14.

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

[0046] Overall working principle: The user inserts the adjustment plug 14 into the power socket 13, and the lifting clamping assembly clamps the outside of the adjustment plug 14. When a short circuit occurs, the high temperature causes the C-shaped thermal conductive locking piece 37 to deform outward, thereby expanding the inner diameter of the C-shaped thermal conductive locking piece 37. This releases the C-shaped thermal conductive locking piece 37 from the elastic reset rod. Under the action of elastic force, the elastic reset rod quickly resets, causing the C-shaped thermal conductive locking piece 37 to slide outside the elastic reset rod to cut off the power. Simultaneously, the movement of the elastic reset rod drives the linkage guide wheel to rotate rapidly, pulling the guide rope 24. The guide rope 24 pulls the lifting clamping assembly through the guide wheel assembly. Unplug the adjustment plug 14 to disconnect the power socket 13 from the adjustment plug 14, achieving a double power-off function. After the short circuit problem is resolved, the C-type thermal conductive locking piece 37 also cools down and resets. Pull the elastic reset rod to make the C-type thermal conductive locking piece 37 snap back into the elastic reset rod, thereby pulling the lifting clamping assembly to reset and causing the adjustment plug 14 to be inserted back into the power socket 13 for power supply. Insert the housing 1 into the opened cabinet door panel and move the housing 1 until the opened door panel opening is aligned with the side clamping seat. Activate the retractable wheel to adjust the side clamping seat to expose the side of the door panel opening for clamping, thus fixing the housing 1 to the door panel opening. Therefore, disassembly is also very convenient.

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

[0048] An inner spring reset cylinder 30 is installed on one side of the L-shaped fixed plate 29, and a conductive inner post 38 is installed at the output end of the inner spring reset cylinder 30. An insulating reset rod 2 is installed at the end of the conductive inner post 38 away from the inner spring reset cylinder 30, and a pull ring 3 is installed at the end of the insulating reset rod 2.

[0049] Local working principle: When the user pulls the pull ring 3, the insulating reset rod 2 is moved. The inner spring reset cylinder 30 is connected to the insulating reset rod 2 and has a built-in high-strength spring, so it can realize the function of quick reset and the function of the insulating reset rod 2 sliding along the axial direction of the inner spring reset cylinder 30 when the pull ring 3 is pulled.

[0050] In this embodiment, the linkage guide wheel includes a linkage gear 33, a rack 10, a side rotating rod 32, a guide rope disc 34, and a guide rope post 35;

[0051] A C-shaped fixing plate 12 is installed at the inner tail of the housing 1, and a side rotating rod 32 is installed on one side of the C-shaped fixing plate 12 via a bearing. A linkage gear 33 is installed on the outer side of the side rotating rod 32, and a guide rope disc 34 is sleeved on the upper and lower sides of the outer side of the linkage gear 33. A guide rope post 35 is installed on the inner side of the C-shaped fixing plate 12. A rack 10 is provided on the side of the insulating reset rod 2 facing the linkage gear 33, and the rack 10 meshes with the linkage gear 33. The guide rope 24 is wound around the outer side of the guide rope disc 34 and passes through the guide rope post 35.

[0052] Local working principle: The movement of the insulating reset rod 2 synchronously drives the rack 10 to move. Because the rack 10 and the linkage gear 33 mesh with each other, the rack 10 adjusts the rotation of the linkage gear 33. The linkage gear 33 then pulls the guide rope 24 to move. The guide rope 24 is wrapped around the outside of the guide rope disc 34 and passes through the guide rope post 35.

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

[0054] The rear end of the housing 1 is equipped with a second guide wheel 22 and a first guide wheel 21, and a guide rope hole 23 is provided at the rear end of the housing 1. The guide rope 24 passes through the guide rope hole 23, passes through the bottom of the second guide wheel 22, and passes through the top of the first guide wheel 21 to connect with the lifting clamping assembly.

[0055] Local working principle: The guide rope 24 is guided by the second guide wheel 22 and the first guide wheel 21 to pull the lifting and clamping assembly.

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

[0057] The tail of the housing 1 is equipped with a limiting support sliding rod 19, and the end of the limiting support sliding rod 19 is equipped with a spring fixing plate 17. A sliding piece 20 is sleeved on the outside of the limiting support sliding rod 19. A return spring 18 is installed between the sliding piece 20 and the spring fixing plate 17. A lifting clamping seat 16 is installed on one side of the sliding piece 20. An inner limiting sliding rod 31 is installed inside the lifting clamping seat 16. Two sets of clamping bars 15 are sleeved on the outside of the inner limiting sliding rod 31. An inner clamping spring 11 is installed between the two sets of clamping bars 15. The inner clamping spring 11 is sleeved on the outside of 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 bar 15, the adjustment plug 14 is clamped between the two sets of clamping bars 15. By pulling the guide rope 24, a pulling force is generated on the sliding piece 20, causing the sliding piece 20 to slide on the outside of the limiting support sliding rod 19, thereby driving the lifting clamping seat 16 to pull the clamping bar 15 out of the power socket 13, thus realizing the function of quickly separating the adjustment plug 14 from the power socket 13.

[0059] In this embodiment, the take-up and release wheel section includes a take-up and release 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 on the inner end of the housing 1. An adjusting plate 28 is installed in the middle of the end fixing plate 25 via a receiver / discharge motor. A hinge connecting rod 27 is hinged to the outer side of the adjusting plate 28. A limiting sleeve 26 is integrally formed on one side of the end fixing plate 25, and the hinge connecting rod 27 passes through the limiting sleeve 26 and is hinged to a side clamping seat.

[0061] Local working principle: The start of the receiver / discharge motor drives the adjustment plate 28 to rotate, and the adjustment plate 28 adjusts the movement of the hinge link 27. The limit sleeve 26 locks the hinge link 27 to prevent excessive rotation. The movement of the hinge link 27 adjusts the movement of the side clamping seat to achieve the function of pushing the side clamping seat to clamp the side of the door panel.

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

[0063] Local working principle: The movement of the hinged connecting rod 27 adjusts the movement of the C-type clamp 8 inside the side groove 7, so that the C-type clamp 8 extends out of the side groove 7 to clamp the side of the door panel opening.

[0064] In this embodiment, a top cover 5 is installed on the top of the housing 1, a display screen 6 is installed at the end of the housing 1, a C-shaped thermal conductive card 37 is connected to the circuit board 9 through the circuit board connecting line 36, a conductive inner post 38 is connected to the socket conductive line 39, and the socket conductive line 39 is connected to the inner end of the power socket 13 through a wire.

The guide rope (24) pulls the lifting clamping assembly through the guide wheel assembly to pull out the adjustment plug (14), thereby releasing the contact between the power socket (13) and the adjustment plug (14), and realizing double power off; Step 4: After the short circuit problem is solved and the C-type thermal conductive clamping piece (37) is cooled and reset, the elastic reset rod is pulled to make the C-type thermal conductive clamping piece (37) clamped onto the elastic reset rod again, and the lifting clamping assembly is pulled to reset; Step 5: The adjusting plug (14) is inserted into the power socket (13) again to supply power, the housing (1) is inserted into the opened door panel of the electric cabinet, the housing (1) is moved until the opened door panel opening is aligned with the side clamping seat, the retracting wheel is started to adjust the side clamping seat to expose the side of the door panel opening to clamp the housing (1) on the door panel opening.
