Description

Technical Field

[0001] The present application relates to the technical field of electric power error prevention, and in particular to an intelligent AC high-voltage electric tester and an electric test management method. Background Art

[0002] In power production, in order to reduce casualties and property losses caused by accidental touching of live parts, it is usually necessary to detect whether the equipment to be operated carries high voltage electricity before production operations. The detection method is to use a traditional contact electrometer to contact the equipment to be operated and test the electricity through the electrometer.

[0003] However, when the electrical tester is testing equipment, there is a situation where there is no contact with the equipment to be tested, so that the test result of the energized equipment is also not energized, resulting in inaccurate test results and the risk of casualties and property losses.

[0004] Therefore, how to detect whether the tester is in contact with the device under test during the test, improve the accuracy of the test, and reduce the risk of casualties and property losses is a technical problem that needs to be solved urgently. Summary of the invention

[0005] The present application provides an intelligent AC high-voltage tester and a test management method, which can detect whether the tester is in contact with the device under test during the test, improve the accuracy of the test, and reduce the risk of casualties and property losses.

A first through hole is provided at one end of the housing. The connecting rod is slidably arranged in the first through hole along its axial direction, and one end of the connecting rod passing through the housing is used to connect the test electrode. The main control board is provided with a test circuit, and the test circuit is electrically connected to the test electrode to obtain a test signal of the device to be tested. The detection assembly includes a sensing member and a detection member, the sensing member is fixedly arranged in the housing, the sensing member is electrically connected to the main control board, and the detection member is connected to the connecting rod. The detection member can move relative to the housing with the connecting rod, and has a detection position close to or away from the sensing member. When the test electrode contacts the device to be tested, the trigger sensing member outputs a contact signal between the test electrode and the device to be tested to the main control board. The main control board is used to receive the test signal and the contact signal, and output the test information based on the test signal and the contact signal; wherein the test information includes two types of non-charged information that can distinguish between the test without contact and the test without charge.

[0008] The technical solution of the embodiment of the present application is to connect the test electrode through a connecting rod, and the connecting rod can move relative to the shell along the axial direction of the connecting rod, and a sensing component is fixedly arranged in the shell, and a detection component is arranged on the connecting rod. Whether the sensing component and the detection component move relative to each other will cause the sensing component to output a contact signal between the test electrode and the device to be tested to the main control board, so as to judge whether the test electrode is in contact with the device to be tested, thereby detecting whether the intelligent AC high-voltage tester is in contact with the device to be tested, thereby improving the accuracy of electrical testing and reducing the risk of casualties and property losses.

[0009] In some embodiments, the detection element is a magnetic element, and the induction element is a Hall sensor.

[0010] The technical solution of the embodiment of the present application determines whether the sensing element and the detection element have relative movement, which leads to whether the Hall effect occurs between the sensing element and the detection element, thereby causing the sensing element to output a contact signal between the test electrode and the device to be tested to the main control board, and determines whether the test electrode is in contact with the device to be tested, thereby detecting whether the intelligent AC high-voltage tester is in contact with the device to be tested, thereby improving the accuracy of electrical testing and reducing the risk of casualties and property damage accidents.

The trigger rod is located in the housing, one end of the trigger rod is connected to the connecting rod, and the induction member is disposed at the other end of the trigger rod.

[0012] The technical solution of the embodiment of the present application reduces the probability of the trigger rod of the detection element being charged by setting the sensing element on the trigger rod, and the trigger rod is an insulating element, thereby reducing the influence of the current on the Hall effect generated by the sensing element and the detection element, and improving the accuracy of detecting whether the test electrode is in contact with the device to be tested.

[0013] In some embodiments, the intelligent AC high-voltage tester further includes an elastic component, which includes a sliding member, a stopper and an elastic member. The sliding member is located in the housing, and along the axial direction of the connecting rod, the sliding member can be slidably sleeved on the connecting rod.

At the same time, when the test electrode contacts the device to be tested, when the housing and the connecting rod move relative to each other, the sliding member and the housing can compress the elastic member, and when the test electrode is separated from the device to be tested, the elastic member can be reset, driving the connecting rod to reset, which is conducive to improving the convenience of resetting the connecting rod.

[0015] In some embodiments, a limit piece is disposed at the end of the guide post, and the limit piece is used to prevent the sliding piece from detaching from the guide post.

[0016] The technical solution of the embodiment of the present application reduces the risk of the sliding member detaching from the guide post and improves the reliability of the sliding cooperation between the guide post and the sliding member by setting a limiter at the end of the guide post. At the same time, when the test electrode contacts the device to be tested, when the housing and the connecting rod move relative to each other, the sliding member and the housing can compress the elastic member, and when the test electrode is separated from the device to be tested, the elastic member can be reset to drive the connecting rod to reset, which is conducive to improving the convenience of resetting the connecting rod.

[0017] In some embodiments, the elastic component further includes a support member, which is located in the housing and can be slidably mounted on the connecting rod along the axial direction of the connecting rod. The elastic member is mounted on the connecting rod, and the two ends of the elastic member are respectively in contact with the sliding member and the support member; a limiting portion is provided on the connecting rod, and the limiting portion is used to prevent the support member from moving in a direction away from the sliding member.

[0018] The technical solution of the embodiment of the present application is that the support member is slidably mounted on the connecting rod, the two ends of the elastic member are respectively in contact with the sliding member and the support member, and a limit portion is provided on the connecting rod to reduce the movement of the support member in the direction away from the sliding member, which is conducive to improving the reliability of the compressed elastic member.

[0021] In some embodiments, a socket is provided on the first end face of the connecting rod. One end of the bent hook test electrode and one end of the straight needle test electrode are both provided with a plug-in column and a first flange portion, the plug-in column is used to be inserted into the socket, the first flange portion protrudes from the outer circumference of the plug-in column, and the first flange portion is used to abut the first end face. The intelligent AC high-voltage tester also includes a threaded sleeve, the threaded sleeve includes a barrel and a second flange portion, the barrel is used to be sleeved on one end of the connecting rod and threadedly connected to the connecting rod, the second flange portion protrudes from the inner circumference of the barrel, and the second flange portion is used to abut the side of the first flange portion away from the first end face.

[0022] The technical solution of the embodiment of the present application connects the connecting rod through a threaded sleeve, which facilitates the disassembly and assembly of the connecting rod and the test electrode, and the second flange portion of the threaded sleeve abuts against the first flange portion of the test electrode, reducing the risk of separation of the test electrode and the connecting rod, which is beneficial to improving the reliability of the connection between the test electrode and the connecting rod.

The high-voltage coupling plate and the ground coupling plate are electrically connected to the main control board respectively, and the connecting rod is arranged on the side of the high-voltage coupling plate away from the ground coupling plate.

[0024] The technical solution of the embodiment of the present application realizes the electrical testing function of the intelligent AC high-voltage tester by electrically connecting the high-voltage signal plate to the connecting rod, and the high-voltage coupling plate and the ground coupling plate are electrically connected to the main control board respectively.

[0071] Please refer to Figures 1 to 4 , see also Figure 7 , Figure 1 A schematic diagram of the structure of an intelligent AC high-voltage tester provided in some embodiments of the present application, Figure 2 This is a schematic diagram of the structure of the intelligent AC high-voltage tester provided in some other embodiments of the present application. Figure 3 A schematic diagram of the cooperation between the intelligent AC high-voltage tester and the device to be tested provided in some embodiments of the present application, Figure 4 Schematic diagram of the cooperation between the intelligent AC high-voltage tester and the device to be tested provided in other embodiments of the present application, Figure 7Schematic diagram of a housing provided in some embodiments of the present application. The present application provides an intelligent AC high-voltage electrometer 1, which includes a housing 10, a connecting rod 20, a main control board 90 and a detection assembly. A first through hole 11 is provided at one end of the housing 10. The connecting rod 20 is slidably inserted into the first through hole 11 along its axial direction, and one end of the connecting rod 20 that passes through the housing 10 is used to connect the test electrode 30. The main control board 90 is provided with a test circuit, and the test circuit is electrically connected to the test electrode 30 to obtain a test signal of the device under test. The detection assembly includes a sensing member 60 and a detection member 50, the sensing member 60 is fixedly arranged in the housing 10, the sensing member 60 is electrically connected to the main control board 90, and the detection member 50 is connected to the connecting rod 20. The detection member 50 can move relative to the housing 10 following the connecting rod 20, and has a detection position close to or away from the sensing member 60. When the test electrode 30 contacts the device under test 2, the trigger sensing member 60 outputs a contact signal between the test electrode 30 and the device under test 2 to the main control board 90. The main control board 90 is used to receive the power test signal and the contact signal, and output power test information based on the power test signal and the contact signal; wherein the power test information includes two types of no-power information that can distinguish between no-contact during power test and no-power during power test.

[0072] In some embodiments, the intelligent AC high-voltage tester 1 may include a shell 10 and a connecting rod 20. A first through hole 11 is provided at one end of the shell 10. One end of the connecting rod 20 passes through the first through hole 11 and extends into the interior of the shell 10. The other end of the connecting rod 20 is located outside the shell 10.

[0073] In some embodiments, the connecting rod 20 can slide through the first through hole 11 along the axial direction X of the connecting rod, that is, along the axial direction X of the connecting rod, the distance that the connecting rod 20 extends into the interior of the housing 10 can be increased or decreased.

[0074] In some embodiments, the axial direction of the connecting rod can be represented by the direction indicated by the letter X in the figure.

[0075] In some embodiments, in order to facilitate the connection between the test electrode 30 and the device under test 2, the test electrode 30 may be located outside the housing 10. That is, the test electrode 30 may be connected to one end of the connecting rod 20 located outside the housing 10.

[0076] It should be noted that, according to the different shapes of the test electrode 30, there can be multiple types of the test electrode 30, the test electrode 30 can be detachably connected to the connecting rod 20, and the test electrode 30 can be replaced based on the use scenario of the intelligent AC high-voltage tester 1. The description of the test electrode 30 refers to the embodiments below.

[0077] In some embodiments, the contact between the test electrode 30 and the device under test 2 can be understood as the contact between the test electrode 30 and a possibly charged part of the device under test 2 . When the device under test 2 is charged, the test electrode 30 can be electrically connected to the device under test 2 .

[0078] In some embodiments, when the test electrode 30 contacts the device under test 2 , the housing 10 can be pushed or pulled so that the test electrode 30 abuts against the device under test 2 , and the housing 10 and the connecting rod 20 are relatively displaced.

[0079] In some embodiments, the detection member 50 may be directly connected to the connecting rod 20 or indirectly connected to the connecting rod 20 .

[0080] In some embodiments, the connecting rod 20 moves relative to the housing 10 , so that the detection member 50 and the sensing member 60 move relative to each other, thereby triggering the sensing member 60 to output a signal to the main control board 90 indicating that the test electrode 30 is in contact with the device under test 2 .

[0081] In some embodiments, the electrical test signal received by the main control board 90 can be a signal indicating that the device under test 2 is not powered or is powered, and the contact signal received by the main control board 90 can be a signal indicating that the test electrode 30 is in contact with the device under test 2 or a signal indicating that the test electrode 30 is not in contact with the device under test 2.

[0082] In some embodiments, the main control board 90 can output power test information, and the power test information includes two types of no-power information that can distinguish between no contact during power test and no power during power test.

[0083] For example, when the power test information indicates that the power test is not in contact and the power test is not energized, it is impossible to identify whether the device under test 2 is energized, and a new power test is required.

[0084] When the power test information is that the power test contact is on and the power test is not energized, it can be identified that the device under test 2 is energized.

[0085] When the power test information is power test contact and the power test is not energized, it can be identified that the device under test 2 is not energized.

[0086] The technical solution of the embodiment of the present application is to connect the test electrode 30 through the connecting rod 20, and the connecting rod 20 can move relative to the shell 10 along the axial direction X of the connecting rod, and the sensing member 60 is fixedly arranged in the shell 10, and the detection member 50 is arranged on the connecting rod 20. Whether the sensing member 60 and the detection member 50 move relative to each other determines whether the sensing member 60 outputs a contact signal between the test electrode 30 and the device under test 2 to the main control board 90, and determines whether the test electrode 30 is in contact with the device under test 2, thereby detecting whether the intelligent AC high-voltage tester 1 is in contact with the device under test 2, thereby improving the accuracy of the test and reducing the risk of casualties and property losses.

[0087] Please refer to Figure 5 , Figure 5 Schematic diagram of a detection element and a sensing element provided in some embodiments of the present application, wherein Figure 5The middle is the state when the connecting rod and the housing have not moved relative to each other. In some embodiments, the detection member 50 can be a magnetic member, and the induction member 60 can be a Hall sensor. The magnetic member can be a magnetic steel, and the magnetic steel includes a first part and a second part with opposite polarities, wherein the magnetic property of the connection between the first part and the second part is weak. In order to distinguish that the first part and the second part have opposite magnetic properties, the first part and the second part are represented by the letters N and S respectively in the figure.

[0088] The sensing part 60 can be a Hall plate 61 on which a Hall element 62 is arranged. The Hall plate 61 can be connected to the power supply 91 of the intelligent AC high-voltage tester 1 (the connection method can be direct connection, or the power supply 91 can be connected to the main control board 90, and the Hall plate 61 can be connected to the main control board 90), so that the Hall plate 61 is energized.

[0089] In the initial state, in the axial direction X of the connecting rod, the connection between the first part and the second part of the magnetic steel can be located in the same plane as the Hall element 62 , so that a low level signal is generated on the Hall element 62 .

[0090] When the connecting rod 20 moves relative to the housing 10, the connection between the first part and the second part of the magnet moves away from the Hall element 62. At this time, the Hall element 62 and the magnet produce a Hall effect, so that a high-level signal is generated on the Hall element 62. The Hall plate 61 receives the change in the signal, thereby determining that the magnet and the sensing element 60 have undergone relative displacement, so that the sensing element 60 outputs a signal to the main control board 90 indicating that the test electrode 30 is in contact with the device under test 2.

[0091] When the test electrode 30 is separated from the device to be tested 2, the connecting rod 20 is reset, and the magnetic steel moves close to the Hall element 62 and returns to the initial state.

[0092] The method of detecting whether the test electrode 30 is in contact with the device to be tested 2 is not limited thereto, and may also be:

[0093] The detection member 50 is a light source transmitter, and the induction member 60 is a light source sensor. A light source transmitter, such as an infrared transmitter, is arranged at the end of the connecting rod 20 away from the test electrode 30, and a light source receiver or a light source sensor is fixed in the housing 10. In the initial state, the light source receiver can receive the light emitted by the light source transmitter. When the test electrode 30 contacts the device 2 to be tested, the connecting rod 20 and the housing 10 move relative to each other, so that the light source transmitter and the light source receiver move relative to each other, and the light source receiver cannot receive the light emitted by the light source transmitter, thereby judging that the intelligent AC high-voltage tester 1 contacts the device 2 to be tested.

[0094] Alternatively, the detection member 50 is a circuit switch, and the induction member 60 is a circuit. A circuit switch is provided at one end of the connecting rod 20 away from the test electrode 30, and the circuit is fixed in the housing 10. In the initial state, the circuit switch is turned on, so that the circuit is turned on. When the test electrode 30 contacts the device to be tested 2, the connecting rod 20 and the housing 10 move relative to each other, so that the circuit switch moves, thereby disconnecting the circuit. By disconnecting the circuit, it is determined that the intelligent AC high-voltage tester 1 contacts the device to be tested 2.

[0095] The technical solution of the embodiment of the present application determines whether the sensing member 60 and the detection member 50 have relative movement, resulting in whether the Hall effect occurs between the sensing member 60 and the detection member 50, thereby causing the sensing member 60 to output a contact signal between the detection electrode 30 and the device under test 2 to the main control board 90, and determines whether the detection electrode 30 is in contact with the device under test 2, thereby detecting whether the intelligent AC high-voltage tester 1 is in contact with the device under test 2, thereby improving the accuracy of electrical testing and reducing the risk of casualties and property losses.

[0096] Please refer to Figures 1 to 4 In some embodiments, the intelligent AC high-voltage tester 1 further includes a trigger rod 70 , which is an insulating member. The trigger rod 70 is located in the housing 10 , one end of the trigger rod 70 is connected to the connecting rod 20 , and the detection member 50 is disposed at the other end of the trigger rod 70 .

[0097] In order to reduce the influence of current on the Hall effect of the detection member 50 and the induction member 60, the component connecting the detection member 50 can be set as an insulating member. In some embodiments, the two ends of the trigger rod 70 are respectively connected to the connecting rod 20 and the detection member 50, and the trigger rod 70 can be an insulating member.

[0098] In some embodiments, the trigger rod 70 may be made of plastic, rubber, etc.

[0099] In some embodiments, the connection between the connecting rod 20 and the trigger rod 70 may be a threaded connection. The connecting rod 20 is provided with a threaded hole, and one end of the trigger rod 70 is connected to the threaded hole.

[0100] The technical solution of the embodiment of the present application reduces the probability that the trigger rod 70 on which the detection member 50 is set is charged by setting the detection member 50 on the trigger rod 70, and the trigger rod 70 is an insulating member, thereby reducing the influence of the current on the Hall effect generated by the detection member 50 and the sensing member 60, and improving the accuracy of detecting whether the test electrode 30 is in contact with the device 2 to be tested.

[0101] Please refer to Figures 1 to 4 , and refer to Figure 6 and, Figure 8 and Fig. 9 , Figure 6 for Figure 1 A in the enlarged view, Figure 8 A schematic diagram of the interior of a housing provided in some embodiments of the present application, Fig. 9 A schematic diagram of the structure of a sliding member provided for some embodiments of the present application. In some embodiments, the intelligent AC high-voltage electrometer 1 further includes an elastic component 40, and the elastic component 40 includes a sliding member 41, a stopper 42, and an elastic member 43. The sliding member 41 is located in the housing 10, and along the axial direction X of the connecting rod, the sliding member 41 is slidably sleeved on the connecting rod 20. The stopper 42 is provided on the connecting rod 20, and is used to prevent the sliding member 41 from detaching from the connecting rod 20 in a direction away from the test electrode 30. The elastic member 43 is provided between the housing 10 and the sliding member 41. Among them, a guide hole 411 is provided on the sliding member 41, and a guide column 12 is provided on the inner side of the housing 10, and the guide column 12 extends along the axial direction X of the connecting rod, and the guide column 12 is slidably penetrated in the guide hole 411.

[0102] In some embodiments, the elastic member 43 may be a spring.

[0103] In some embodiments, the sliding member 41 can be a plate-shaped member, the sliding member 41 is arranged in the shell 10, and one end of the connecting rod 20 located in the shell 10 is passed through the sliding member 41. The sliding member 41 can slide relative to the connecting rod 20 along the axial direction X of the connecting rod.

[0104] In some embodiments, the stopper 42 may be a bolt, which is sleeved on the outer circumference of the connecting rod 20 and fixedly connected to the connecting rod 20. The stopper 42 may abut against a side of the sliding member 41 away from the test electrode 30 to prevent the sliding member 41 from detaching from the connecting rod 20 in a direction away from the test electrode 30.

[0105] In some embodiments, a guide column 12 may be disposed on the inner side of the housing 10 , and the guide column 12 and the first through hole 11 may be disposed on the same wall surface of the housing 10 .

[0106] One end of the guide post 12 is disposed on the inner wall surface of the housing 10 and extends inwardly along the axial direction X of the connecting rod.

[0107] In some embodiments, the guide post 12 may be integrally formed with the housing 10 .

[0108] In some embodiments, the sliding member 41 may be provided with a guide hole 411 , and the guide hole 411 may be penetrated through two end surfaces of the sliding member 41 in the thickness direction.

[0109] In some embodiments, the sliding member 41 may include a main body 413 and a protrusion 412. The main body 413 and the protrusion 412 may be integrally formed. The protrusion 412 protrudes from the surface of the main body 413 facing the guide column 12. The guide hole 411 is penetrated by the protrusion 412 and the main body 413, thereby increasing the distance of the guide hole 411 on the axial direction X of the connecting rod and reducing the risk of deviation between the guide column 12 and the sliding member 41.

[0110] In some embodiments, the elastic member 43 is disposed between the housing 10 and the sliding member 41. When the housing 10 is pulled, the connecting rod 20 moves relative to the housing 10 toward the outside of the housing 10, and at this time, the housing 10 pushes one end of the elastic member 43, and the sliding member 41 is abutted by the stopper 42 and cannot move in a direction away from the test electrode 30, that is, the other end of the elastic member 43 cannot move, and at this time, the elastic member 43 is compressed.

[0111] According to the technical solution of the embodiment of the present application, the elastic member 43 is disposed between the housing 10 and the sliding member 41, the guide column 12 of the housing 10 is slidably disposed in the guide hole 411 of the sliding member 41, and the stopper 42 disposed on the connecting rod 20 is used to prevent the sliding member 41 from being separated from the connecting rod 20 in the direction away from the test electrode 30, thereby reducing the risk of the sliding member 41 being separated from the connecting rod 20 and improving the reliability of the sliding connection between the sliding member 41 and the connecting rod 20. At the same time, when the test electrode 30 contacts the device under test 2 and the housing 10 and the connecting rod 20 move relative to each other, the sliding member 41 and the housing 10 can compress the elastic member 43, and when the test electrode 30 is separated from the device under test 2, the elastic member 43 can be reset to drive the connecting rod 20 to reset, thereby improving the convenience of resetting the connecting rod 20.

[0112] Please refer to Figures 1 to 4 , Figure 6 and Fig. 9 In some embodiments, a limit member 121 is disposed at the end of the guide post 12 , and the limit member 121 is used to prevent the sliding member 41 from detaching from the guide post 12 .

[0113] In some embodiments, a limit member 121 may be provided at the end of the guide column 12. The limit member 121 may be fixedly connected to the guide column 12, and the limit member 121 passes through the sliding member 41. The limit member 121 may abut against a side of the sliding member 41 away from the first through hole 11 to prevent the sliding member 41 from detaching from the guide column 12.

[0114] In some embodiments, the limit member 121 can be a screw or a threaded rod, and the guide column 12 can be provided with a mounting hole 122. One end of the limit member 121 is arranged in the mounting hole 122, and the other end of the limit member 121 passes through the sliding member 41 and can abut against the side of the sliding member 41 away from the first through hole 11.

[0115] In some embodiments, the elastic member 43 is disposed between the housing 10 and the sliding member 41. When the housing 10 is pushed, the connecting rod 20 moves relative to the housing 10 toward the inside of the housing 10, at which time the guide column 12 moves along with the housing 10, and the stopper 121 abuts against the sliding member 41, thereby driving the sliding member 41 to move, thereby driving one end of the elastic member 43 to move, and at this time the elastic member 43 is compressed.

[0116] The technical solution of the embodiment of the present application reduces the risk of the sliding member 41 being separated from the guide post 12 by providing a stopper 121 at the end of the guide post 12, thereby improving the reliability of the sliding fit between the guide post 12 and the sliding member 41. At the same time, when the test electrode 30 contacts the device under test 2, when the housing 10 and the connecting rod 20 move relative to each other, the sliding member 41 and the housing 10 can compress the elastic member 43, and when the test electrode 30 is separated from the device under test 2, the elastic member 43 can be reset, driving the connecting rod 20 to reset, which is conducive to improving the convenience of resetting the connecting rod 20.

In some embodiments, the elastic component 40 further includes a support member 44, which is located in the housing 10 and can be slidably mounted on the connecting rod 20 along the axial direction X of the connecting rod. The elastic member 43 is mounted on the connecting rod 20, and the two ends of the elastic member 43 are respectively abutted against the sliding member 41 and the support member 44; the connecting rod 20 is provided with a limiting portion 21, which is used to prevent the support member 44 from moving in a direction away from the sliding member 41.

[0118] In some embodiments, the support member 44 may be a gasket, which is sleeved on the connecting rod 20 .

[0119] In some embodiments, one end of the connecting rod 20 located in the housing 10 may have two parts, the outer diameter of one part is smaller than the outer diameter of the other part, so that a step surface is formed at the connection of the two parts, and the part with the smaller outer diameter is closer to the sliding member 41. The support member 44 is sleeved on the part with the smaller outer diameter, and the step surface abuts against the support member 44 to prevent the support member 44 from moving away from the sliding member 41.

[0120] In some embodiments, the elastic member 43 is disposed between the support member 44 and the sliding member 41. When the housing 10 is pushed, the connecting rod 20 moves relative to the housing 10 toward the inside of the housing 10, and the guide column 12 moves with the housing 10, and the limiting member 121 abuts against the sliding member 41, thereby driving the sliding member 41 to move, thereby driving one end of the elastic member 43 to move, and at this time the other end of the elastic member 43 abuts against the support member 44, and the support member 44 is abutted by the limiting portion 21 and cannot move, and at this time the elastic member 43 is compressed.

[0121] In some embodiments, the outer diameter of the support member 44 may be greater than the inner diameter of the first through hole 11, and the elastic member 43 is disposed between the support member 44 and the sliding member 41. When the housing 10 is pulled, the connecting rod 20 moves relative to the housing 10 toward the outside of the housing 10, and the housing 10 pushes the support member 44 to move close to the sliding member 41, and the support member 44 pushes the end of the elastic member 43 abutting against the support member 44 to move, and the sliding member 41 is abutted by the stopper 42 and cannot move in the direction away from the test electrode 30, that is, the other end of the elastic member 43 cannot move, and the elastic member 43 is compressed.

[0122] The technical solution of the embodiment of the present application is that the support member 44 is slidably mounted on the connecting rod 20, the two ends of the elastic member 43 are respectively in contact with the sliding member 41 and the support member 44, and the connecting rod 20 is provided with a limiter 21 to reduce the movement of the support member 44 in the direction away from the sliding member 41, which is conducive to improving the reliability of the compressed elastic member 43. At the same time, when the test electrode 30 contacts the device under test 2, when the housing 10 and the connecting rod 20 move relative to each other, the sliding member 41 and the support member 44 can compress the elastic member 43, and when the test electrode 30 is separated from the device under test 2, the elastic member 43 can be reset to drive the connecting rod 20 to reset, which is conducive to improving the convenience of resetting the connecting rod 20.

[0125] In some embodiments, the straight needle test electrode 32 may be a straight portion, and the outer diameter of the end of the straight needle test electrode 32 away from the connecting rod 20 may be smaller, so that the straight needle test electrode 32 can contact the device under test 2 in an environment with a small space, or the straight needle test electrode 32 can extend into the inside of the device under test 2. The end of the straight needle test electrode 32 away from the connecting rod 20 can contact the device under test 2, and by pushing the housing 10, the test electrode 30 is brought into contact with the device under test 2.

[0126] The technical solution of the embodiment of the present application selectively connects the bent hook test electrode 31 and the straight needle test electrode 32 to the connecting rod 20, and can replace a more suitable test electrode 30 based on the location of the test, which is beneficial to improving the practicality and applicability of the intelligent AC high-voltage tester 1.

[0154] In some embodiments, the sensing member 60 may be fixed in the inner shell 14. When the test electrode 30 contacts the device under test 2, the housing 10 is pushed or pulled, and the inner shell 14 and the outer shell 13 move together relative to the connecting rod 20, and the connecting rod 20 and the trigger rod 70 move together relative to the inner shell 14 and the outer shell 13, so that the detection member 50 disposed on the trigger rod 70 moves relative to the sensing member 60, so that the sensing member 60 outputs a signal to the main control board 90 indicating that the test electrode 30 is in contact with the device under test 2.

[0155] Since the inner shell 14 is disposed in the outer shell 13, the outer shell 13 can protect the inner shell 14 and reduce the risk of damage and dirtiness of the inner shell 14. In some embodiments, when the outer shell 13 is damaged or heavily soiled, the outer shell 13 and the inner shell 14 can be disassembled and replaced with a new outer shell 13.

[0156] In some embodiments, the inner shell 14 may not only be used to install the sensor 60 , but may also be used to install other relatively expensive electronic components, such as a main control board 90 , an interface board 96 , and the like.

[0157] In some embodiments, the main control board 90 , the power supply 91 and the coupling plate assembly 93 may all be disposed in the inner shell 14 .

[0158] In some embodiments, the high-voltage signal electrode plate 92 may be disposed in the outer shell 13 , and along the axial direction X of the connecting rod, the high-voltage signal electrode plate 92 may be closer to the first through hole 11 than the inner shell 14 .

[0159] In some embodiments, the elastic component 40 connects the connecting rod 20 and the housing 13 .

[0160] According to the technical solution of the embodiment of the present application, the cost of the sensing element 60 is relatively high. By arranging the sensing element 60 in the inner shell 14, and the inner shell 14 and the outer shell 13 are detachably connected, when the outer shell 13 is damaged or dirty, the outer shell 13 can be replaced without replacing the sensing element 60, which helps to reduce costs.

[0161] Please refer to Figures 1 to 4 as well as Fig.16 In some embodiments, the intelligent AC high-voltage tester 1 further includes a positioning module 94 and a communication module 95. The positioning module 94 is disposed in the inner shell 14 and electrically connected to the main control board 90, and the positioning module 94 is used to detect the position of the intelligent AC high-voltage tester 1. The communication module 95 is disposed in the inner shell 14 and electrically connected to the main control board 90, and the communication module 95 is used to exchange information with the outside world.

[0162] In some embodiments, the positioning module 94 may be a Beidou antenna, which is used to locate the intelligent AC high-voltage tester 1. The positioning module 94 detects the position of the intelligent AC high-voltage tester 1, and can transmit the detected position information to the background. When the operator of the background confirms that the intelligent AC high-voltage tester 1 is located at the correct position of the device to be tested 2, the operator on site is notified to start the test.

[0163] In some embodiments, the communication module 95 can be a 4G antenna or other communication equipment. The communication module 95 can transmit the data of the intelligent AC high-voltage tester 1 to the background, such as the position detection information of the positioning module 94, the test results of the intelligent AC high-voltage tester 1, the results of the intelligent AC high-voltage tester 1 detecting whether the test electrode 30 is in contact with the device to be tested 2, etc., and accept instructions from the background, such as starting the test, retesting, stopping the test, etc.

[0165] It should be noted that the main control board 90 also has a communication function and can be used to exchange information with the outside world. The communication module 95 can enhance the communication capability of the main control board 90 .

[0166] In some embodiments, the positioning module 94 has a positioning element. In order to reduce the risk of the positioning element facing the ground or the positioning signal being blocked by the environment (such as trees, buildings, etc.), the positioning module 94 can be tilted relative to the axial direction X of the connecting rod. The tilt angle can be 30 degrees, 45 degrees, 60 degrees, etc.

[0167] According to the technical solution of the embodiment of the present application, different devices to be tested 2 need to use intelligent AC high-voltage testers 1 with different voltage applicable ranges. The location of the intelligent AC high-voltage tester 1 is detected by the positioning module 94, which reduces the risk of misdetecting other devices to be tested 2 that are beyond their voltage applicable range, thereby helping to reduce the risk of casualties and property losses. At the same time, the communication module 95 exchanges information with the outside world, which helps to improve the convenience of the background issuing instructions for the on-site operation of the intelligent AC high-voltage tester 1.

The undervoltage light 9633 may be used to indicate that the power of the intelligent AC high-voltage tester 1 is insufficient.

[0176] For example, when the device to be tested 2 is energized, the energized light 9631 lights up, and when the intelligent AC high-voltage tester 1 is turned on, the running light 9632 lights up.

[0177] The technical solution of the embodiment of the present application is to electrically connect the interface board 96 provided with a speaker 962 and an indicator light 963 to the main control board 90, so as to improve the convenience for the operator to obtain the processing information of the intelligent AC high-voltage electroscope 1.

The bottom cover 143 is connected to the upper shell 141 and the lower shell 142 at one end away from the first through hole 11.

[0180] In some embodiments, the upper shell 141 , the lower shell 142 and the bottom cover 143 can be formed separately and then connected by gluing or snapping to form a receiving cavity 146 .

[0181] In some embodiments, the bottom cover 143 can be located on the side of the interface board 96 away from the first through hole 11.
