Description

Technical Field

[0001] The present invention relates to the technical field of overvoltage protection for transformer substations, and in particular to an overvoltage protection device for transformer substations. Background Art

[0002] A substation overvoltage protector is a device specially designed to limit overvoltage in the power grid. It protects electrical equipment from damage by absorbing, limiting or blocking overvoltage. It is widely used in power systems and is an important device for ensuring power safety.

[0003] Usually, when the overvoltage protector receives a signal that the voltage of the protected line exceeds the predetermined maximum value, it will disconnect the power supply or reduce the voltage of the controlled equipment, thereby protecting the voltage safety of the entire circuit. In substations, overvoltage protectors are usually installed at the equipment's incoming lines, busbars, and outgoing lines to limit and eliminate the damage to the equipment caused by overvoltage in the system.

[0004] After using the overvoltage protector for a long time, the wiring port on the voltage protector will be damaged due to external pulling factors or its own lifespan, making it impossible to perform overvoltage safety protection work on the entire circuit subsequently. In this case, the staff will usually disconnect the wiring port from the wiring port of the external device, and then repair and replace the new wiring port for use. However, in this way, after the wiring port of the external device is disconnected, it will leave the current area due to its own gravity, causing the wiring port to fall to the ground and cause collision damage to the wiring port. In order to prevent the wiring port from falling to the ground, the staff will choose to clamp the wiring port and then repair and replace the wiring port on the voltage protector. This method not only affects the staff's entire replacement and maintenance rate, but also distracts the staff's energy and attention from the wiring port of the external device, resulting in safety risks when the staff works with distracted energy.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0036] See also Figures 1 to 10 , which is the first embodiment of the present invention, provides a technical solution: an overvoltage protection device for a substation, comprising a voltage protector 1 and a wiring port 2 arranged on the voltage protector 1, the wiring port 2 on the voltage protector 1 is used to connect between a power line and a load line to ensure that current passes normally, a mounting base 3 is arranged on the voltage protector 1, the mounting base 3 is used to facilitate the installation of the voltage protector 1, when the voltage protector 1 is installed on the mounting base 3, the voltage protector 1 is fixed on the external device through the installation between the mounting base 3 and the external device, and at the same time, a certain fixed protection effect can be played on the voltage protector 1 in this process, an adjustment component 4 is arranged on the mounting base 3, and the adjustment component 4 is used to facilitate the movement of the wiring port 2 for easy maintenance after the wiring port 2 is damaged;

[0037] The adjusting assembly 4 includes a fixed arc plate 41 arranged on one side of the mounting seat 3, and a groove is provided in the middle of the fixed arc plate 41, and the groove is used to facilitate the swing plate 44 arranged on the supporting slide plate 42 to have enough moving space, and will not affect the overall movement of the swing plate 44, and the array is movably arranged on the fixed arc plate 41. The supporting slide plate 42 is sleeved and slid on the fixed arc plate 41, and the wiring port 2 is placed and fixed by the supporting fixing plate 43 arranged on the supporting slide plate 42. The supporting fixing plate 43 arranged on the supporting slide plate 42 is used to facilitate the placement of the wiring port 2, and at the same time cooperates with the supporting slide plate 42, and slides under the action of the supporting slide plate 42, so that the wiring port 2 can be temporarily driven by the supporting slide plate 42 to be replaced after being damaged.

[0038] The swing plate 44 is arranged on the support slide plate 42, and the swing plate 44 is rotatably arranged on the support slide plate 42 through a fixed rod. Through the broken line shape of the swing plate 44, when the swing plate 44 rotates, the limiting rod 45 arranged on the swing plate 44 can be separated from the limiting hole 411 on the fixed arc plate 41, so that the support slide plate 42 can release the locking state with the fixed arc plate 41;

[0039] A limit rod 45 is arranged on the side of the swing plate 44 close to the fixed arc plate 41. The limit rod 45 is used to cooperate with the limit hole 411 on the fixed arc plate 41. Through the contact and engagement of the two, the locking and releasing between the supporting slide plate 42 and the fixed arc plate 41 can be controlled by the swing plate 44.

[0040] A first spring 441 is provided on the side of the swing plate 44 away from the limiting rod 45, and one end of the first spring 441 away from the swing plate 44 is fixedly connected to the supporting slide plate 42. The first spring 441 acts on the swing plate 44 through its own elastic force, so that when the swing plate 44 is not squeezed, the limiting rod 45 provided on the swing plate 44 can be inserted into the limiting hole 411 on the fixed arc plate 41, and the supporting slide plate 42 and the fixed arc plate 41 are locked together through the limiting action of the two.

[0041] The fixed arc plate 41 is provided with an array of limit holes 411, and the limit holes 411 are a kind of conical opening connected with the straight hole. When the limit rod 45 swings, the conical opening formed on the limit hole 411 can prevent the limit rod 45 from being unable to be smoothly inserted into the straight hole in the limit hole 411 during the swinging process. A matching support plate 442 is provided at the end of the swing plate 44 away from the first spring 441. The matching support plate 442 has an arc chamfer on the side away from the swing plate 44. Under the action of the arc chamfer, the matching support plate 442 is squeezed by the arranged oblique push block 433, so that the matching support plate 442 rotates, thereby driving the swing plate 44 to swing synchronously.

[0042] The mounting base 3 is provided with supporting components 5 in an array for supporting the supporting plate 43 . The supporting plate 43 is symmetrically provided with rotating components 6 for rotating, so that the wiring port 2 is conveniently moved by the supporting plate 43 .

[0043] During use, the wiring port 2 on the voltage protector 1 is first placed inside the annular guide plate 435 on the supporting fixing plate 43, and then the upper surface of the wiring port 2 is bonded through the bonding plate 7, and then the wiring port of the external device is sleeved on the conductive column 53 on the L-shaped support plate 52, and then the wiring port is pressed to drive the L-shaped support plate 52 to move downward on the fixed support frame 51. During the displacement process, the wiring port will squeeze the locking block 625 to open to both sides. During the opening process, until the upper end of the wiring port is completely under the locking block 625, the locking block 625 will be reset under the action of the third spring 626. The reset locking block 625 will form a bonding relationship between the wiring port, the conductive column 53 and the wiring port 2. Under the action of the conductive column 53, the current channel between the wiring port 2 and the wiring port is circulated, and then after the two are fixed, the starting circuit can be passed, thereby realizing overvoltage protection for the entire circuit. Example

[0044] See also Figures 1 to 11 , which is the second embodiment of the present invention, and this embodiment is different from the first embodiment in that:

[0045] The support assembly 5 includes a fixed support frame 51 arranged in an array on the mounting seat 3. The fixed support frame 51 is L-shaped, and the other end thereof is open, so that the support plate 43 can be driven by the support slide plate 42 to detach from the inside of the fixed support frame 51, thereby facilitating the maintenance and replacement of the wiring port 2 placed on the support plate 43 by the staff, and an L-shaped support plate 52 movably arranged on the fixed support frame 51. The L-shaped support plate 52 and the fixed support frame 51 are in a plug-in movable relationship, and a conductive column 53 is arranged on the L-shaped support plate 52. Under the action of the conductive column 53, the placed wiring ports 2 can be energized to facilitate the passage of voltage and current;

[0046] The conductive pillar 53 is arranged on the L-shaped support plate 52, and the conductive pillar 53 penetrates the L-shaped support plate 52. After being plugged between the wiring port of the external device and the conductive pillar 53, the wiring port is pressed, so that the L-shaped support plate 52 and the wiring port are simultaneously lowered, and then under the action of the clamping block 625, the wiring port is squeezed by the clamping block 625, so that the two are connected to form a whole, and the conductive pillar 53 arranged at the same time will be connected to the inside of the wiring port 2, so that the entire circuit channel is circulated, thereby preventing the interface from falling off due to the shaking of the wiring port during use;

[0047] The slide bars 54 are arranged in an array on the L-shaped support plate 52, and the fixed cylinders 55 are arranged in an array on the fixed support frame 51, and the fixed cylinders 55 and the slide bars 54 are engaged and slidable. A circular plate is arranged on the side of the slide bar 54 away from the L-shaped support plate 52, and the circular plate is fitted with the inner wall of the fixed cylinder 55. When the L-shaped support plate 52 is driven by the wiring port to move downward, the slide bar 54 will move synchronously inside the fixed cylinder 55, so that the second spring 56 arranged inside the fixed cylinder 55 will be compressed by the circular plate on the slide bar 54.

[0048] The compressed second spring 56 will provide elastic force. When the wiring port is not locked by the locking block 625, the second spring 56 will release the elastic force to lift up the L-shaped support plate 52 and the wiring port, thereby facilitating the movement of the wiring port 2. The second spring 56 is arranged inside the fixed tube 55. The second spring 56 is used to provide elastic force to facilitate the subsequent resetting of the wiring port and the L-shaped support plate 52.

[0049] A multi-stage extension rod 511 is symmetrically arranged on one side of the fixed support frame 51 close to the support slide plate 42, and a T-shaped clamping cavity 512 is arranged on one end of the multi-stage extension rod 511 away from the fixed support frame 51. The T-shaped clamping cavity 512 is used to be clamped and limited with the T-shaped block 431 on the support fixing plate 43, so that when the support fixing plate 43 moves, the multi-stage extension rod 511 will be synchronously extended under the action of the T-shaped clamping cavity 512 to support the movement of the support fixing plate 43. At the same time, during the entire movement process, the support fixing plate 43 as a whole can also be in contact with the multi-stage extension rod 511;

[0050] A T-shaped block 431 is symmetrically arranged on one side of the support fixing plate 43 close to the multi-stage extension rod 511, and the T-shaped block 431 is engaged and limited with the T-shaped engagement cavity 512. A buffer pad 521 is arranged on the end of the L-shaped support plate 52 away from the sliding rod 54. The buffer pad 521 is a flexible material and is used to prevent the L-shaped support plate 52 from descending too fast, causing the L-shaped support plate 52 to directly hit the bonding plate 7.

[0051] The supporting fixed plate 43 is symmetrically provided with arc-shaped guide plates 432, and the arc-shaped guide plates 432 are provided on both sides of the matching support plate 442. A sliding engagement relationship is formed between two push rods on the matching support plate 442 and the arc-shaped notches on the arc-shaped guide plates 432. When the matching support plate 442 is squeezed by the oblique push block 433, the matching support plate 442 can swing through the limit of the arc-shaped guide plates 432 when rotating.

[0052] An oblique push block 433 is movably provided on the support fixing plate 43, and one side of the oblique push block 433 has an oblique surface, which fits with the arc chamfer on the matching support plate 442. Under the extrusion of the oblique push block 433, the matching support plate 442 is forced to rotate, and the oblique push block 433 is close to the support fixing plate 43. The side of the support fixing plate 43 forms a card-engaging sliding relationship with the card block on the oblique push block 433 through the card slot on the support fixing plate 43. The oblique push block 433 is provided with a lower pressing plate 434. When the wiring port 2 needs to be repaired or replaced, the lower pressing plate 434 can be pressed to squeeze the oblique push block 433 against the matching support plate 442;

[0053] An annular guide plate 435 is provided on the supporting fixing plate 43. The annular guide plate 435 is conductive. When in use, the wiring port 2 is directly placed on the outside of the annular guide plate 435 to temporarily fix the wiring port 2. At the same time, the bonding plate 7 can be lowered to directly bond to the surface of the wiring port 2 to prevent the wiring port 2 from shaking randomly.

[0054] During use, when the lower pressure plate 434 descends, the fixed plate 436 arranged on the lower pressure plate 434 descends synchronously. Under the action of the fixed plate 436, the engaging and sliding guide plate 65 can push the rack 64 to move. The movement of the rack 64 will drive the matching gear 63 engaged on the rotating rod 61 to rotate. After the rotating rod 61 rotates, the power is transmitted to the rotating cylinder 62, thereby driving the engaging block 625 arranged on the rotating cylinder 62 to rotate synchronously. The rotation angle is 90 degrees. After the rotation is completed, the engaging block 625 will no longer limit the wiring port on the external device, so that the wiring port can be reset under the action of the second spring 56, so that when the supporting fixing plate 43 is pulled later, the supporting fixing plate 43 can take the wiring port 2 out of the current position, so that the staff can repair and replace the wiring port 2, and the whole process will not change the current position of the wiring port of the external device, so that when the new wiring port 2 is repaired and replaced later, the wiring port 2 can be directly docked with the wiring port, avoiding the need to recalibrate the docking.

[0055] The remaining structures are the same as those of Example 1. Example

[0056] See also Figures 1 to 12 , which is the third embodiment of the present invention. This embodiment is different from the first and second embodiments in that:

[0057] The rotating assembly 6 includes a rotating rod 61 symmetrically arranged on the supporting fixed plate 43. An array of protrusions is arranged on one end of the rotating rod 61 away from the supporting fixed plate 43, which is used to engage and slide with the sliding groove 627 inside the rotating cylinder 62, so that when the rotating rod 61 rotates, it can drive the rotating cylinder 62 to rotate synchronously. The rotating cylinder 62 sleeved on the rotating rod 61 has a sufficient cavity inside the rotating cylinder 62. Under the rotation of the rotating rod 61, the rotating cylinder 62 can rotate through the cooperation between the sliding groove 627 provided inside the rotating cylinder 62 and the protrusion on the rotating rod 61;

[0058] The mating gear 63 provided on the rotating rod 61 is used to rotate under the drive of the rack 64, meshing with the rack 64 provided on one side of the mating gear 63, and the guide plate 65 provided on one side of the rack 64, and the guide plate 65 is used to press down through the fixed plate 436 provided on the lower pressure plate 434, so that the guide plate 65 can push the rack 64 to move, and under the movement of the rack 64, the mating gear 63 drives the rotating rod 61 to rotate 90 degrees.

[0059] A sliding groove 627 is provided in the internal array of the rotating cylinder 62, an oblique groove 651 is provided on the guide plate 65, and a fixing plate 436 is symmetrically provided on the side of the lower pressure plate 434 close to the guide plate 65, and the fixing plate 436 and the oblique groove 651 are engaged and slid. When the lower pressure plate 434 is pressed down, the fixing plate 436 is driven to squeeze the oblique groove 651 on the guide plate 65, so that the guide plate 65 drives the rack 64 to move laterally, and the movement of the rack 64 drives the meshing matching gear 63 to rotate, thereby making the rotating rod 61 and the rotating cylinder 62 rotate synchronously.

[0060] An L-shaped positioning rod 621 is provided on the side of the rotating cylinder 62 close to the rotating rod 61. The L-shaped positioning rod 621 is used to engage and slide with the arc-shaped guide rail 622 on the bonding plate 7. An arc-shaped guide rail 622 is provided on the end of the L-shaped positioning rod 621 away from the rotating cylinder 62, and the arc-shaped guide rail 622 engages and slides with the L-shaped positioning rod 621. The bonding plate 7 is provided on the arc-shaped guide rail 622. The bonding plate 7 and the arc-shaped guide rail 622 are fixedly connected, and the bonding plate 7 is used to press down the wiring port 2 to provide a certain clamping force, so that the wiring port 2 will not shake easily.

[0061] An orienting plate 623 is provided at one end of the rotating cylinder 62 away from the rotating rod 61, and a moving rod 624 is symmetrically provided on the orienting plate 623. The moving rod 624 and the orienting plate 623 are engaged and slidable. A locking block 625 is provided at one end of the moving rod 624. The wiring port of the external device is limited by the locking block 625, so that the wiring port, the conductive column 53 and the wiring port 2 are spliced ​​together.

[0062] A locking block 625 is provided at one end of the moving rod 624. One side of the locking block 625 has an inclined surface, and a straight groove is opened on the locking block 625 for locking the locking block 625 with the directional plate 623. A third spring 626 is sleeved on the moving rod 624, and the third spring 626 is used to provide a rebound force to cause the locking block 625 to reset.

[0063] During use, when it is found that the wiring port 2 on the voltage protector 1 is damaged, the lower pressure plate 434 is pressed down to drive the oblique push block 433 to move synchronously, and the matching support plate 442 is driven to rotate under the action of the oblique push block 433. During the rotation process, the matching support plate 442 will drive the swing plate 44 on the supporting slide plate 42 to swing. At this time, the limiting rod 45 on the swing plate 44 will be separated from the limiting hole 411 on the fixed arc plate 41, so that the supporting slide plate 42 can be adjusted in position, and the rotating assembly 6 can be synchronously driven to rotate during the downward pressing process of the lower pressure plate 434, so that the upper surface of the wiring port of the external equipment is no longer constrained, and the wiring port will be pushed by the second spring 56. The movable wiring port is reset with the L-shaped support plate 52, thereby disengaging the contact between the conductive column 53 and the wiring port 2, facilitating the subsequent displacement of the wiring port 2. At the same time, the arc guide rail 622 arranged on the fitting plate 7 can engage and slide between the cylinder and the L-shaped positioning rod 621 to prevent the rotating cylinder 62 from rotating excessively. After the rotation is completed, the lower pressure plate 434 is released, and the support plate 442 is reset under the action of the first spring 441 arranged on the swing plate 44, so that the limiting rod 45 is reinserted into the limiting hole 411 on the fixed arc plate 41 to form a locking relationship, thereby preventing the wiring port 2 from shaking when the staff replaces and repairs the wiring port 2, thereby affecting the time and efficiency of the entire maintenance.

[0064] The remaining structures are the same as those of embodiments 1 and 2.

[0065] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
