Description

Technical Field

[0001] The present invention relates to the technical field of transformers, and more particularly to a power transformer with direct current leakage protection. Background Art

[0002] The power transformer is a soft magnetic electromagnetic component, mainly used for power transmission, voltage conversion and insulation isolation. It plays a vital role in power supply technology and power electronics technology. In the process of power transmission and distribution, this device uses the principle of electromagnetic induction to achieve voltage rise and fall to meet the power requirements of different equipment. It also has functions such as isolating electrical interference and matching impedance to ensure the normal operation of the equipment and extend its service life.

[0003] The power transformer itself is a live device, so some power transformers are equipped with leakage protection devices, which can quickly and automatically disconnect the circuit or send out an alarm signal when the insulation of the electrical equipment fails, that is, when leakage occurs, to prevent people from electric shock. Its working principle is based on the residual current protection function. When the residual current in the protected circuit exceeds the set value, it can quickly and automatically disconnect the circuit, thereby achieving the purpose of protecting personal safety and equipment.

[0004] However, when the power transformer with a leakage protection device is used, because the leakage protection device and the transformer are integrated, when the leakage protection device or the transformer in the power transformer fails, the entire power transformer needs to be replaced, or the entire power transformer needs to be disassembled for repair. However, because a single leakage protection device or transformer is damaged, the entire power transformer needs to be replaced, making the remaining intact single leakage protection device or transformer unable to continue to be used, which reduces the practicality of the power transformer and causes a waste of resources.

[0020] (2) This solution sets up a fixing component.

This can effectively prevent the No. 2 slide bar and the driving plate from shaking left and right in the No. 2 slide slot, thereby improving the stability of the connection component and further improving the practicality of the power transformer.

[0021] (3) This solution sets up a release component, and manually presses down the No. 3 slide bar to drive the downward pressure rod to move, thereby driving the two trapezoidal blocks to be inserted into the two trapezoidal grooves and move, and then driving the two No. 1 sliders to move closer to each other, so that the two No. 1 blocks are moved into the No. 6 slide groove, which is convenient for driving the No. 2 slide bar to move. At the same time, the wear on the No. 1 block and the groove is reduced, the service life of the fixing component is increased, and the stability of the connecting component is further improved.

[0046] When the existing power transformer is in use, when a single leakage protection device or transformer inside the power transformer is damaged, the entire power transformer needs to be replaced, so that the remaining intact single leakage protection device or transformer cannot be used any more, which reduces the practicality of the power transformer and causes waste of resources. Therefore, a connecting component 5 is provided. When the transformer body 1 and the leakage protector body 2 are installed together, the two positioning rods 522 are first inserted into the two positioning holes 521 so that the transformer body 1 and the leakage protector body 2 are aligned, and then the leakage protector body 2 is continued to be driven to move toward the transformer body 1 so that the fixing plate 52 is inserted into the fixing groove 51, thereby pushing the first slide bar 54 to the first slide groove 521. 3, and at the same time drives the No. 1 rack 510 to move, thereby driving the No. 1 gear 59 to rotate in the No. 1 connecting groove 58, and then drives the No. 2 rack 511 to move in the No. 2 sliding groove 55 in the opposite direction to the No. 1 sliding rod 54, and at the same time drives the No. 2 sliding rod 56 to move in the opposite direction to the No. 1 sliding rod 54, thereby driving the driving plate 57 to move, so that the connecting rod 514 moves to the middle position in the driving through groove 515, thereby releasing the restriction on the U-shaped slider 513, and then drives the U-shaped slider 513 to move to the outside of the No. 3 sliding groove 512 through the No. 1 spring 525, so that the U-shaped slider 513 is inserted into the No. 1 groove 516, thereby fixing the fixing plate 52 in the fixing groove 51, and then the transformer body 1 and the leakage protector body 2 are connected.

When the transformer body 1 and the leakage protector body 2 need to be separated, the moving block 518 is manually pushed to move in the fourth slide groove 517 in the direction away from the fixed groove 51, thereby continuing to drive the first slide rod 54 to move into the first slide groove 53, thereby driving the driving plate 57 to move, so that the connecting rod 514 moves to one end in the driving through groove 515, thereby driving the U-shaped slider 513 to move downward, so that the U-shaped slider 513 is pulled out of the first groove 516, thereby releasing the fixation of the fixed plate 52, so that the transformer body 1 and the leakage protector body 2 are separated. The body 1 and the leakage protector body 2 can be separated, so that it is convenient to disassemble the damaged transformer body 1 or the leakage protector body 2, and then reinstall the new transformer body 1 or the leakage protector body 2, so that the remaining intact single transformer body 1 or the leakage protector body 2 can continue to be used, thereby improving the practicality of the power transformer and reducing the waste of resources. The dust baffle 520 slides inside the fifth slide groove 519 to prevent dust from entering the fourth slide groove 517 when the power transformer is in use. At the same time, the dust ring 524 engages with the dust groove 523 to prevent dust from entering the joints of the transformer body 1 or the leakage protector body 2 to affect the use of the power transformer.

[0047] like Figure 4 , Figure 6 , Figure 7 , Figure 8 As shown, a fixing component 6 is arranged between the two No. 2 slide grooves 55, and the fixing component 6 includes a No. 6 slide groove 61 jointly opened between the two No. 2 slide grooves 55, and two No. 1 sliders 62 are slidably connected inside the No. 6 slide groove 61, and a No. 2 spring 65 is arranged between the two No. 1 sliders 62, and a No. 1 clamping block 63 is fixedly connected to the side of the outer surface of the two No. 1 sliders 62 away from the No. 2 spring 65, and a clamping groove 64 is opened on the side of the outer surface of the two No. 2 slide rods 56 close to the No. 1 clamping block 63.

[0048] like Figure 6 , Figure 7 , Figure 8 As shown, a release assembly 7 is provided at the upper end of the inner wall of the No. 6 slide 61, and the release assembly 7 includes a No. 1 mounting groove 72 opened at the upper end of the inner wall of the No. 6 slide 61, and the upper end of the No. 1 mounting groove 72 extends to the inside of the No. 4 slide 517, and the upper surfaces of the two No. 1 sliders 62 are both provided with a trapezoidal groove 71, and the No. 1 mounting groove 72 is slidably connected to a T-shaped rod 74, and the lower surfaces of the T-shaped rod 74 are fixedly connected to trapezoidal blocks 73 on both sides, and the trapezoidal blocks 73 are slidably connected to the trapezoidal groove 71. The upper end of the T-shaped rod 74 is fixedly connected to a downward pressing rod 75, and a No. 7 slide groove 77 penetrating the moving block 518 is provided in the middle position of the upper surface of the moving block 518. A No. 3 slide rod 78 is slidably connected inside the No. 7 slide groove 77. The outer surface of the No. 3 slide rod 78 is fixedly connected to a limiting block 79 around it. A No. 1 T-shaped slide groove 710 is provided on the lower surface of the No. 3 slide rod 78. A T-shaped slide rod 76 is fixedly connected to the upper surface of the downward pressing rod 75, and the T-shaped slide rod 76 is slidably connected to the No. 1 T-shaped slide groove 710.

[0049] In the above embodiment, the driving plate 57 is driven to move by the second slide bar 56, so as to control the movement of the connecting rod 514 in the driving groove 515, and whether the U-shaped slider 513 can be inserted into the first groove 516 can be controlled, and then whether the fixing plate 52 is fixed in the fixing groove 51 is controlled, which is convenient for the installation and disassembly of the transformer body 1 and the leakage protector body 2. However, because the second slide bar 56 and the driving plate 57 slide in the second slide groove 55, the second slide bar 56 and the driving plate 57 are easy to shake left and right in the second slide groove 55, which affects the stability of the connection component 5 and reduces the practicality of the power transformer. Therefore, a fixing component 6 is provided. When the movable plate 57 moves, when the connecting rod 514 moves to the middle position in the driving groove 515, the restriction on the U-shaped slider 513 is released, and at the same time, the two No. 1 sliders 62 are driven by the No. 2 spring 65 to move to the outside of the No. 6 slide groove 61 at the same time, thereby driving the two No. 1 clamping blocks 63 to move to the outside of the No. 6 slide groove 61 at the same time, so that the two No. 1 clamping blocks 63 are respectively inserted into the two clamping grooves 64, thereby fixing the two No. 2 slide bars 56 in the No. 2 slide groove 55, which can effectively prevent the No. 2 slide bar 56 and the driving plate 57 from sliding in the No. 2 slide groove 55, thereby improving the stability of the connection component 5 and further improving the practicality of the power transformer.

[0050] In the above embodiment, the two No. 1 clamping blocks 63 are controlled to be respectively inserted into the two clamping grooves 64 to fix the two No. 2 slide bars 56 in the No. 2 slide bars 55. However, because the position of the No. 1 clamping block 63 inserted into the clamping groove 64 is V-shaped, when the No. 2 slide bar 56 is driven to move, the No. 1 clamping block 63 can be pushed into the No. 6 slide bar 61. However, because the No. 1 clamping block 63 is inserted into the clamping groove 64, it takes a certain amount of force to drive the No. 2 slide bar 56 to move, which makes it difficult to drive the No. 2 slide bar 56 to move, and it is easy to cause wear to the No. 1 clamping block 63 and the clamping groove 64, which reduces the service life of the fixing component 6 and further affects the stability of the connecting component 5. Therefore, a release component 7 is provided. When it is necessary to drive the No. 2 slide bar 56 to move, the No. 3 slide bar 78 is first manually pressed down to drive the pressing rod 75 to move downward, and at the same time drive the T-shaped rod 74 to move downward in the No. 1 mounting groove 72. The two first blocks 63 are moved into the sixth slide groove 61, and then the second slide bar 56 can be driven to move through the moving block 518, thereby facilitating driving the second slide bar 56 to move, and at the same time reducing the wear on the first block 63 and the slot 64, improving the service life of the fixing assembly 6, and further improving the stability of the connecting assembly 5, and through the sliding connection between the T-shaped slide bar 76 and the No. 1 T-shaped slide groove 710, the No. 3 slide bar 78 can drive the lower pressure rod 75 to move up and down, and at the same time, the moving range of the No. 3 slide bar 78 is limited by the limit block 79.

[0051] like Figure 8 , Fig. 9 , Fig.10 As shown, a stabilizing component 8 is provided on the lower surface of the lower pressure rod 75, and the stabilizing component 8 includes No. 2 grooves 81 opened on both sides of the lower surface of the lower pressure rod 75, and an L-shaped block 82 is fixedly connected to the position corresponding to the two No. 2 grooves 81 on one side of the inner wall of the No. 1 mounting groove 72, and a No. 8 slide groove 83 is commonly opened between the two No. 2 grooves 81, and a No. 2 slider 84 is slidably connected inside the No. 8 slide groove 83, and a No. 3 spring 86 is provided between the two No. 2 sliders 84, and a No. 2 clamping block 85 is fixedly connected to the side of the outer surface of the two No. 2 sliders 84 away from the No. 3 spring 86.

[0052] The second spring 65 is compressed and the second spring 65 is provided with elastic potential energy to drive the two first blocks 63 to move toward the outside of the sixth slide groove 61, so that the third slide rod 78 needs to be pressed down all the time to prevent the two first blocks 63 from moving toward the outside of the sixth slide groove 61, and then the moving block 518 can drive the second slide rod 56 to move at the same time, so that when the second slide rod 56 is driven to move by the moving block 518, the third slide rod 78 needs to be pressed down all the time, which is not convenient for manually pushing the moving block 518 to move, thereby driving the second slide rod 56 to move. When inserted into the two trapezoidal grooves 71, the lower pressure rod 75 is driven to move downward at the same time, so that the two L-shaped blocks 82 are respectively inserted into the two No. 2 grooves 81, and then the No. 3 spring 86 drives the two No. 2 sliding blocks 84 to move toward the outside of the No. 8 sliding groove 83, thereby driving the two No. 2 clamping blocks 85 to move toward the outside of the No. 8 sliding groove 83, so that the two No. 2 clamping blocks 85 are respectively stuck under the short ends of the two L-shaped blocks 82, thereby fixing the L-shaped block 82 inside the No. 2 groove 81, and then fixing the lower pressure rod 75 inside the No. 1 mounting groove 72, so that after pressing down the No. 3 sliding rod 78 to drive the lower pressure rod 75 to move into the No. 1 mounting groove 72, the lower pressure rod 75 is automatically fixed in the No. 1 mounting groove 72, and then the moving block 518 can be manually pushed to move, thereby driving the No. 2 sliding rod 56 to move. There is no need to press down the No. 3 sliding rod 78 and push the moving block 518 to move at the same time, which is convenient for driving the No. 2 sliding rod 56 to move, thereby improving the convenience of using the release assembly 7.

[0053] like Fig. 9 , Fig.10 , Fig.11 As shown, a control assembly 9 is arranged above the two No. 2 sliders 84, and the control assembly 9 includes No. 2 mounting grooves 91 opened on both sides of the upper end of the inner wall of the No. 8 slide groove 83, and the two No. 2 mounting grooves 91 are respectively located above the two No. 2 sliders 84, and the upper surfaces of the two No. 2 sliders 84 are fixedly connected to a No. 1 straight rod 92, and the No. 1 straight rod 92 is slidably connected to the No. 2 mounting groove 91, and the upper ends of the outer surfaces of the two No. 1 straight rods 92 close to each other are fixedly connected to a No. 3 straight rod 92. Rack 93, and the positions of the two No. 3 racks 93 are staggered up and down, a No. 2 connecting groove 94 is opened between the two No. 2 mounting grooves 91, a No. 2 gear 95 is slidably connected inside the No. 2 connecting groove 94, and the No. 2 gear 95 is meshedly connected with the two No. 3 racks 93, and a No. 2 straight rod 96 is fixedly connected to the side of the outer surface of the No. 1 straight rod 92 away from the No. 3 rack 93, one end of the No. 2 straight rod 96 passes through the lower pressure rod 75, and the No. 2 straight rod 96 is close to the fixed groove 51.

[0054] like Fig. 9 , Fig.10 , Fig.11 As shown, a No. 3 mounting groove 97 is opened at a position corresponding to the No. 2 straight rod 96 on one side of the inner wall of the No. 1 mounting groove 72, and one end of the No. 3 mounting groove 97 extends into the fixed groove 51, and a No. 4 slide rod 98 is slidably connected inside the No. 3 mounting groove 97, and a movable plate 99 is fixedly connected to the side of the lower surface of the No. 4 slide rod 98 away from the No. 2 straight rod 96, and the movable plate 99 extends into the fixed groove 51 and is slidably connected to the fixed groove 51.

[0055] like Fig.10 As shown, a second T-shaped slot 910 is provided at the lower end of the inner wall of the fixed slot 51 below the movable plate 99 , a T-shaped slider 911 is slidably connected in the second T-shaped slot 910 , and the T-shaped slider 911 is fixedly connected to the lower surface of the movable plate 99 .

[0056] The second step of locking cam 76 is to lock the locking cam 76 in place and lock the locking cam 76. When the locking cam 76 is unlocked, the locking cam 76 will be unlocked, and the locking cam 76 will be unlocked. The No. 1 straight rod 96 moves into the No. 2 mounting groove 91, thereby driving the No. 1 straight rod 92 and the No. 3 rack 93 on one side to move into the No. 2 mounting groove 91, and then the No. 2 gear 95 is meshed with the two No. 3 racks 93, so that the two No. 3 racks 93 move closer to each other at the same time, thereby driving the two No. 1 straight rods 92 to move closer to each other at the same time, and then driving the No. 2 sliders 84 to move closer to each other at the same time, so that the two No. 2 blocks 85 move into the No. 8 slide groove 83, thereby releasing the fixation of the No. 2 block 85 on the L-shaped block 82, and then automatically releasing the fixation of the lower pressure rod 75, thereby improving the practicality of the stabilizing assembly 8, and improving the stability of the movement of the movable plate 99 through the sliding connection between the T-shaped slider 911 and the No. 2 T-shaped slide groove 910.

[0057] Instructions for use: When installing the transformer body 1 and the leakage protector body 2, first insert the two positioning rods 522 into the two positioning holes 521, so that the fixing plate 52 is inserted into the fixing groove 51, thereby pushing the No. 1 slide bar 54 to move, and then the No. 1 gear 59 is meshed with the No. 1 rack 510 and the No. 2 rack 511, thereby driving the No. 2 slide bar 56 and the No. 1 slide bar 54 to move in the opposite direction, thereby driving the driving plate 57 to move, so that the connecting rod 514 moves to the middle position in the driving through groove 515, and then the No. 1 spring 525 drives the U-shaped slider 513 to move, so that the U-shaped slider 513 is inserted into the No. 1 groove 516, and at the same time pushes the moving plate 99 to move, thereby releasing the No. 2 clamping block 85 from fixing the L-shaped block 82 through the control component 9 , thereby releasing the fixation of the downward pressure rod 75 by the stabilizing component 8, so that the downward pressure rod 75 can move upward, thereby pulling the trapezoidal block 73 out of the trapezoidal groove 71, and then starting the fixing component 6 to fix the No. 2 slide bar 56. When the transformer body 1 and the leakage protector body 2 are disassembled, the No. 3 slide bar 78 is pressed down to insert the trapezoidal block 73 into the trapezoidal groove 71, thereby releasing the fixation of the No. 2 slide bar 56 by the fixing component 6, and at the same time starting the stabilizing component 8 so that the trapezoidal block 73 can be stably inserted into the trapezoidal groove 71, and then pushing the moving block 518 to pull the U-shaped slider 513 out of the No. 1 groove 516, and then manually separating the transformer body 1 and the leakage protector body 2, thereby disassembling the transformer body 1 and the leakage protector body 2.
