Description

Technical Field

[0001] The invention belongs to the technical field of lightning arrester detection, and in particular relates to a fully automatic lightning arrester live testing device and method. Background Art

[0002] The main function of a lightning arrester is to prevent the overvoltage generated by lightning from invading substations or other buildings along the line. Its main structure generally includes the arrester body, shed, high-voltage terminals, and a discharge counter. When conducting live detection of the arrester, it is generally necessary to obtain the voltage phase data of the high-voltage terminal and the mutual inductance current signal between the arrester and the discharge counter, and judge the performance of the arrester after processing by the detector.

[0003] During the test, the operator is required to maintain a safe distance. Therefore, the existing detection device generally uses an insulating rod for operation to obtain voltage phase data and current signals. The Chinese invention patent with application number 202010411376.7 discloses a live detection device for a lightning arrester, which forms an annular area around the high-voltage end drainage line through an arc rod and a connecting rod to perform voltage detection. Although this method will not fall, the high-voltage end drainage line has an irregular shape, and its annular area is not in close contact and fixation with the high-voltage end drainage line. When the operator is away from the insulating rod, the shaking of the insulating rod may cause poor contact or even loss of contact, affecting the collection of the voltage phase signal. Summary of the invention

[0004] The purpose of the present invention is to provide a fully automatic lightning arrester live testing device and method in order to solve the above problems.

[0005] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0006] A fully automatic lightning arrester live testing device, comprising

[0007] An insulating rod assembly used to deliver the base assembly to the side of the arrester;

[0008] A base assembly, which is used to set the clamping assembly, includes a base body, a pair of slide rails arranged on the side surface of the base body, and a pair of slide sleeves sliding on the slide rails, the slide rails are provided with a second elastic member for pushing the two slide sleeves to move toward the center, and an unlockable one-way locking member is provided between the slide sleeve and the slide rail, and the one-way locking member is used to limit the slide sleeve to move only toward the center;

[0009] A clamping assembly, which is used to clamp the arrester, comprises a clamping petal arranged on the sliding sleeve, and the surfaces of the two clamping petals are both hingedly provided with support rods, and the two support rods are used to prevent the sliding sleeve from moving toward the center after the heads of the two support rods abut against each other;

[0010] The detection mechanism is used to connect the high-voltage terminal of the lightning arrester and perform detection, including a detector and a lap rod arranged on the base body. The lap rod presses the high-voltage terminal downward through a driving structure to cooperate with the clamping petal to abut the umbrella skirt to form a fixation.

[0011] As a further optimization scheme of the present invention, each of the sliding sleeves corresponds to two sliding rails, and a pair of parallel holes are arranged on the surface of the sliding sleeve for respectively passing through the two sliding rails. The two ends of the second elastic member are respectively abutted against the surface of the sliding sleeve and the end of the sliding rail. In order to improve the stability of the sliding sleeve during sliding, each sliding sleeve is guided by two sliding rails so that the clamping petals can be stably stressed during the clamping process.

[0012] As a further optimization scheme of the present invention, the base assembly is slidably set on the top of the insulating rod assembly, wherein the insulating rod assembly includes a base rod and a lifting rod arranged in the base rod for lifting the base assembly upward. In order to improve the convenience of operation, this scheme is achieved by sliding the base assembly on the top of the insulating rod assembly, and also providing a lifting rod as a driving source to facilitate lifting through the lifting drive part.

[0013] As a further optimization scheme of the present invention, the base rod and the lifting rod are made of insulating material, and a lifting drive unit is provided at the bottom of the base rod to drive the lifting rod. This scheme enables the base rod and the lifting rod to meet the insulation requirements by setting the lifting drive unit at the bottom of the base rod to keep it away from the high-voltage area.

[0014] As a further optimization scheme of the present invention, a base with an adjustable initial height is provided at the bottom of the base rod. In this scheme, a suitable height is obtained by providing a base with an adjustable initial height, which facilitates the automatic fixation of the test device.

[0015] As a further optimization scheme of the present invention, the one-way locking piece is unlocked by driving a toggle piece arranged on the clamping petal, wherein a bevel tooth groove is opened on the surface of the slide rail, a sliding portion is slidably arranged in the sliding sleeve, the one-way locking piece is arranged in the sliding portion, and a reset piece is also arranged in the sliding sleeve, which is used to enable the sliding portion to drive the one-way locking piece to leave the bevel tooth groove, a rotating rod is arranged in the clamping petal, and the surfaces of the rotating rod and the sliding portion are mutually provided with bevel tooth protrusions, the bevel tooth protrusions are used to push the sliding portion to drive the one-way locking piece to enter the bevel tooth groove when the rotating rod rotates, and a torsion spring is arranged on the surface of the rotating rod for maintaining the potential energy in the above-mentioned rotation direction, the toggle piece is arranged on the rotating rod, and the toggle piece is toggled by the upper umbrella skirt to drive the rotating rod to rotate.

[0016] Since lightning arresters are generally installed at a certain height, it is difficult for operators at the bottom to align the clamping petals with the appropriate clamping position. Therefore, a toggle piece is provided to sense the shed of the lightning arrester. Under the support of the upper shed, the toggle piece drives the rotating rod to rotate so that the one-way locking piece does not work, and the clamping petals can slide freely. When there is no shed above, the one-way locking piece is locked, and the clamping petals can only move one-way toward the center, thereby clamping the lower surface of the uppermost shed.

[0017] As a further optimization scheme of the present invention, a hinge seat and a hinge are arranged on the top of the base body, the lap rod is arranged on the hinge, and an extension arm is also arranged in the hinge, and the driving structure includes a sliding rod slidably arranged in the base body for pushing the extension arm, and the sliding rod is pushed by a lifting rod, and a first elastic member is also arranged between the lifting rod and the base body. In order to make the lap rod have fixing ability, this scheme drives them together through the lifting rod to obtain clamping ability, and the lifting drive part of the lifting rod is arranged below the base rod to maintain a safe distance.

[0018] As a further optimization scheme of the present invention, the lap rod has a pair, and each is fixedly connected to an extension arm, and each pair of lap rods and the extension arm are rotatably connected to the hinge through an axle rod, and the hinge axis of the axle rod and the hinge are perpendicular, wherein a convex rod is provided on the side surface of the sliding rod, and the convex rod is a truncated cone type, which is used to rotate along the axle rod after each pair of lap rods and the extension arm rotates along the hinge, and further, in order to make the lap rod not only have the ability to press down, but also have the ability to clamp toward the center, when the lap rod is rotated and overlapped on the high-voltage terminal, the sliding rod continues to move upward, which will cause the convex rod to be squeezed upward, and the two extension arms have a tendency to open outward along the axle rod, and the lap rod has a tendency to clamp inward.

[0019] In order to apply the above-mentioned test device, the present invention also proposes a method for performing live testing on a lightning arrester based on the above-mentioned test device, comprising the following steps:

[0020] S1: The clamping petals are opened by the support rods, and the clamping petals are placed under the lower end of the top shed. Under the obstruction of the arrester, the support rods are pushed open and no longer support each other, so that the clamping petals are fastened under the shed, and the lap rods press the high-voltage terminal from top to bottom to complete the lap;

[0021] S2: a current transformer is arranged between the arrester and its discharge counter to obtain a current signal flowing through the arrester in the operating state;

[0022] S3: The voltage phase data of the high-voltage terminal is obtained through the detector, and the current signal obtained in step S2 is processed and combined with the voltage phase data to obtain the resistive current flowing through the arrester in the operating state, so as to judge the performance of the arrester.

[0023] The beneficial effects of the present invention are:

DETAILED DESCRIPTION

[0037] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0038] Example 1

[0039] like Figure 1-7 As shown, a fully automatic lightning arrester live testing device includes:

[0040] An insulating rod assembly 1, which is used to deliver the base assembly 2 to the side of the lightning arrester 5;

[0041] The base assembly 2 is used to set the clamping assembly 3, including a base body 21, a pair of slide rails 22 arranged on the side surface of the base body 21, and a pair of slide sleeves 23 sliding on the slide rails 22. The slide rails 22 are provided with a second elastic member 24 for pushing the two slide sleeves 23 to move toward the center. The second elastic member 24 can be set as a spring, and an unlockable one-way locking member 28 is provided between the slide sleeve 23 and the slide rail 22. The one-way locking member 28 is used to limit the slide sleeve 23 to move only toward the center;

[0042] The clamping assembly 3 is used to clamp the arrester 5, and includes a clamping petal 32 arranged on the sliding sleeve 23. The surfaces of the two clamping petals 32 are both hingedly provided with a support rod 33. The two support rods 33 are used to prevent the sliding sleeve 23 from moving toward the center after the heads of the two support rods 33 abut against each other;

[0043] The detection mechanism 4 is used to connect the high-voltage terminal 52 of the lightning arrester 5 and perform detection, and includes a detector 41 and a lap rod 42 arranged on the base body 21. The lap rod 42 presses the high-voltage terminal 52 downward through the driving structure to cooperate with the clamping petal 32 to abut the umbrella skirt 51 to form a fixation.

[0044] In this solution, a pair of clamping petals 32 are provided, which are inserted under the highest umbrella skirt 51 and tightened inwardly to the surface of the lightning arrester 5 through the second elastic member 24. After being locked by the one-way locking member 28, the clamping petals 32 move upward to press the umbrella skirt 51 to obtain the clamping force, and cooperate with the overlapping rod 42 to form a fixed clamping effect, thereby preventing shaking during detection and causing poor contact, thereby improving the stability of the data collection process.

[0045] In order to improve the stability of the sliding sleeve 23 during the sliding process, each sliding sleeve 23 corresponds to two sliding rails 22. A pair of parallel holes are set on the surface of the sliding sleeve 23 for respectively passing through the two sliding rails 22. The two ends of the second elastic member 24 are respectively abutted against the surface of the sliding sleeve 23 and the end of the sliding rail 22. Each sliding sleeve 23 is guided by the two sliding rails 22 so that the clamping petal 32 can be stably stressed during the clamping process. Specifically, the sliding rails 22 are parallel to each other and extend outward from both sides of the base body 21.

[0046] The base assembly 2 is slidably arranged on the top of the insulating rod assembly 1, wherein the insulating rod assembly 1 includes a base rod 12 and a lifting rod 14 arranged in the base rod 12 for lifting the base assembly 2 upward, the base rod 12 and the lifting rod 14 are made of insulating material, and a lifting drive unit 13 is arranged at the bottom of the base rod 12 to drive the lifting rod 14. In order to improve the convenience of operation, this scheme is achieved by sliding the base assembly 2 on the top of the insulating rod assembly 1, and also providing a lifting rod 14 as a driving source, so as to facilitate lifting through the lifting drive unit 13. As a feasible implementation method, the lifting drive unit 13 includes a threaded rod coaxially fixed with the lifting rod 14, and also includes a threaded cylinder and a motor for driving the threaded rod to lift and lower. The lifting rod 14 is limited so that it can only be lifted but not rotated.

[0047] Furthermore, in order to improve the automatic clamping function of the test device, a base 11 with an adjustable initial height is provided at the bottom of the base rod 12, which is used to adjust the base rod 12 to be at a height close to the arrester 5. Preferably, the base 11 can also be provided with a stabilizing structure.

[0048] When the operator actually uses it, since the lightning arrester 5 is generally installed at a certain height, it is difficult for the operator to align the clamping petal 32 with the appropriate clamping position from below. In order to solve this problem, the base assembly 2 can automatically find the topmost umbrella skirt 51 as the clamping support position. In this solution, the one-way locking member 28 is unlocked by driving the toggle member 37 arranged on the clamping petal 32, wherein the surface of the slide rail 22 is provided with an oblique tooth groove 25, a sliding portion 26 is slidably arranged in the sliding sleeve 23, the one-way locking member 28 is arranged in the sliding portion 26, and the sliding sleeve 23 A reset member 27 is also provided inside, which is used to make the sliding portion 26 drive the one-way locking member 28 to leave the oblique tooth groove 25. A rotating rod 34 is provided in the clamping petal 32. The surfaces of the rotating rod 34 and the sliding portion 26 are mutually provided with oblique tooth protrusions 36. The oblique tooth protrusions 36 are used to push the sliding portion 26 to drive the one-way locking member 28 to enter the oblique tooth groove 25 when the rotating rod 34 rotates. A torsion spring 35 is provided on the surface of the rotating rod 34 to maintain the potential energy in the above-mentioned rotation direction. A toggle member 37 is provided on the rotating rod 34. The toggle member 37 is toggled by the upper umbrella skirt 51 to drive the rotating rod 34 to rotate.

[0049] In this solution, a toggle member 37 is provided to sense the shed of the arrester 5. Under the support of the upper shed 51, the toggle member 37 drives the rotating rod 34 to rotate so that the one-way locking member 28 does not work, and the clamping petal 32 can slide freely. When there is no shed 51 above, the one-way locking member 28 is locked, and the clamping petal 32 can only move one-way toward the center, thereby clamping the lower surface of the uppermost shed 51. Specifically, Figure 3 and Fig.11 As shown, when the clamping petal 32 is pushed and clamped on the arrester 5 by the second elastic member 24, the toggle member 37 is blocked by the upper umbrella skirt 51. Fig.10 becomes Fig.11 In the state, the toggle member 37 drives the rotating rod 34 to rotate, such as Figure 3 , 6 As shown in Figure 7, after the rotating rod 34 rotates, the oblique tooth protrusion 36 no longer abuts the sliding part 26. The sliding part 26 can slide toward the rotating rod 34 under the push of the reset member 27, and the one-way locking member 28 leaves the oblique tooth groove 25. The sliding sleeve 23 can slide freely in both directions on the slide rail 22. When the base assembly 2 rises, the clamping petal 32 opens and closes freely to pass over the umbrella skirt 51 upward. When the clamping petal 32 is located below the highest umbrella skirt 51, there is no umbrella skirt 51 to block the toggle member 37, and the rotating rod 34 is reset under the drive of the torsion spring 35. The rotating rod 34 has an angle limit. When resetting, the oblique tooth protrusion 36 just squeezes the sliding part 26 away, and the one-way locking member 28 enters the oblique tooth groove 25, so that the sliding sleeve 23 can only move toward the center, thereby The clamping petal 32 is locked. In this way, the clamping position can be automatically found without visual operation.

[0050] The lap rod 42 needs to be driven by an electrical appliance to complete the clamping action. In this solution, in order to keep the electrical appliance away from the high-voltage terminal 52, the lifting rod 14 is used for joint driving. A hinge seat 43 and a hinge 44 are provided on the top of the base body 21. The lap rod 42 is provided on the hinge 44, and an extension arm 47 is also provided in the hinge 44. The driving structure includes a slide rod 45 slidably provided in the base body 21 for pushing the extension arm 47. The slide rod 45 is pushed by the lifting rod 14. A first elastic member 15 is also provided between the lifting rod 14 and the base body 21. The first elastic member 15 can It is set as a spring. In this solution, the lifting rod 14 first drives the base body 21 to move upward through the first elastic member 15 to find a suitable clamping position. When the clamping flap 32 is locked and no longer moves upward, the base body 21 also stops moving upward, and the overlapping rod 42 reaches the clamping position. The lifting rod 14 continues to rise and compresses the first elastic member 15, and after contacting the sliding rod 45, it pushes the sliding rod 45 upward. The first elastic member 15 plays a role of first lifting the base body 21 and then lifting the sliding rod 45. The sliding rod 45 pushes up the extension arm 47 to press the overlapping rod 42 onto the high-voltage terminal 52.

[0051] In order to apply the above-mentioned test device, the present invention also proposes a method for performing live testing on a lightning arrester based on the above-mentioned test device, comprising the following steps:

[0052] S1: The clamping petal 32 is opened by the support rod 33, and the clamping petal 32 is placed in the lower end of the uppermost shed 51. Under the obstruction of the lightning arrester 5, the support rod 33 is pushed away and no longer abuts against each other for support, so that the clamping petal 32 is fastened under the shed 51, so that the lap rod 42 presses the high-voltage terminal 52 from top to bottom to complete the lap;

[0053] S2: a current transformer is arranged between the arrester 5 and its discharge counter to obtain a current signal flowing through the arrester in the operating state;

[0054] S3: The voltage phase data of the high voltage terminal 52 is obtained through the detector 41, and the current signal obtained in step S2 is processed and combined with the voltage phase data to obtain the resistive current flowing through the arrester in the operating state, so as to judge the performance of the arrester.

[0055] The specific implementation method is as follows: during the preparation work, the two sliding sleeves 23 are pulled to the outermost side to maximize the distance between the two clamping petals 32, and the support rod 33 is rotated until the ends are aligned and abutted to prevent the sliding sleeve 23 from moving toward the center. By holding the insulating rod assembly 1, the clamping petal 32 reaches the height of the lightning arrester 5, and the clamping petal 32 is moved horizontally to be inserted into the lightning arrester 5. The support rod 33 is pushed away by the lightning arrester 5 and no longer supports the clamping petal 32, while the sliding sleeve 23 is pushed by the second elastic member 24 so that the clamping petal 32 clamps the lightning arrester 5, and the height of the base 11 is adjusted to make the base 11 fall to the ground, and then the personnel evacuate. The base assembly 2 is raised by controlling the operation of the lifting drive unit 13. When the base assembly 2 rises to the point where the clamping petal 32 is located below the highest umbrella skirt 51, it stops moving upward. Then the lifting rod 14 continues to rise to push the slide bar 45 to rise, driving the overlapping rod 42 to clamp the high-voltage terminal 52. The lifting drive unit 13 is controlled to stop running. The lifting drive unit 13 can also be automatically stopped by setting a stroke sensor on the slide bar 45. Then, the detector 41 is turned on for detection. It should be noted that the three-phase lightning arrester 5 generally has three, and the test is performed by setting a corresponding number of devices.

[0056] Example 2

[0057] In order to make the lap rod 42 not only have the ability to press down, but also have the ability to clamp toward the center, this embodiment makes further improvements, such as Figure 8-9 As shown, different from the first embodiment, the present embodiment provides a pair of lap rods 42, and each of them is fixedly connected to an extension arm 47, and each pair of lap rods 42 and extension arm 47 are rotatably connected to the hinge 44 through a shaft 48, and the shaft 48 is perpendicular to the hinge axis of the hinge 44, wherein a convex rod 46 is provided on the side surface of the slide bar 45, and the convex rod 46 is a frustum, and is used for each pair of lap rods 42 and extension arm 47 to rotate along the hinge 44 and then rotate along the shaft 48, as shown in FIG. Figure 8 As shown in the perspective, the slide bar 45 moves upward, driving the extension arm 47, the lap rod 42, and the hinge 44 to rotate along the hinge seat 43, so that the lap rod 42 rotates and overlaps the high-voltage terminal. The slide bar 45 continues to move upward to squeeze the protruding rod 46 upward, and the two extension arms 47 have a tendency to open outward along the shaft 48, and the lap rod 42 has a tendency to clamp inward to further obtain the clamping ability.

[0058] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
