[0018] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0019] like Figure 1 and Figure 2 As shown in the figure, this disclosure proposes a mounting system for testing a capacitive voltage transformer 100 (CVT), comprising: a base 1, a lifting device 3, a first rotary telescopic device 4, a first hook 5, a first adapter cable 6, and a control module 2. The lifting device 3 is mounted on the base 1, and the first rotary telescopic device 4 is mounted at the lifting end of the lifting device 3. The lifting device 3 drives the first rotary telescopic device 4 to move vertically up and down. The first hook 5 is mounted at the rotary telescopic end of the first rotary telescopic device 4, and the first rotary telescopic device 4 drives the first hook 5 to rotate vertically and extend horizontally. The first end of the first adapter cable 6 is mounted on the base 1, and the second end of the first adapter cable 6 is connected to the first hook 5. The signal output terminal of the control module 2 is connected to the signal input terminals of the lifting device 3 and the first rotary telescopic device 4, respectively, and the control module 2 controls the lifting device 3 and the first rotary telescopic device 4 to ensure that the first hook 5 is mounted at the target position of the capacitive voltage transformer 100.

[0020] Understandably, since the lifting device 3 is mounted on the base 1, and the first rotary telescopic device 4 is mounted on the lifting end of the lifting device 3, and the first hook 5 is mounted on the rotary telescopic end of the first rotary telescopic device 4, the first hook 5 can be mounted on the base 1 using the lifting device 3 and the first rotary telescopic device 4. Furthermore, the lifting device 3 can be used to achieve vertical movement, and the first rotary telescopic device 4 can be used to achieve horizontal movement. Simultaneously, since the signal output terminal of the control module 2 is connected to the signal input terminals of the lifting device 3 and the first rotary telescopic device 4 respectively, the control module 2 can control the lifting device 3 and the first rotary telescopic device 4, thereby achieving the mechanized adjustment of the spatial position of the first hook 5. This allows the first hook 5 to be efficiently and safely attached to the target position of the capacitive voltage transformer 100, achieving a reliable CVT test.

[0021] It should be noted that the hooking system in this embodiment utilizes the lifting of the lifting device 3 and the rotation and extension of the first rotating telescopic device 4 to achieve mechanized adjustment of the spatial position of the first hook 5, making the hooking operation of the first hook 5 simpler, thereby improving the efficiency of CVT testing. At the same time, it avoids direct operation of the first hook 5 by the operators, thereby greatly reducing the risk of electric shock and improving the safety of CVT testing.

[0022] In addition, the CVT has multiple high-voltage capacitors, such as the upper high-voltage capacitor, the middle high-voltage capacitor, and the lower high-voltage capacitor. The target position can be the bolts of each section of the CVT, that is, the first hook 5 is attached to the middle section bolt.

[0023] The base 1 is used to support the lifting device 3 and other parts. The specific type of the base 1 can be set according to actual needs and there is no limitation. For example, the base 1 may include: a seat at the bottom and a column arranged on the seat, and the various components of the hanging system are arranged on or inside the column.

[0024] The lifting device 3 is used to drive the first hook 5 to rise and fall vertically, and the first rotating telescopic device 4 is used to drive the first hook 5 to rotate vertically and / or extend and retract horizontally. The specific types of the lifting device 3 and the first rotating telescopic device 4 can be set according to actual needs and are not limited thereto.

[0025] The first hook 5 is used to attach to the target position of the CVT. The specific type of the first hook 5 can be set according to actual needs and there is no restriction. For example, the first hook 5 is made of conductive materials such as metal and has a hook-shaped structure, which is attached to the bolts of each section of the CVT.

[0026] The first adapter wire 6 is used for electrical conduction. For example, the pressure testing equipment applies pressure to the CVT through the first adapter wire 6, or the CVT discharges to the grounding network through the first adapter wire 6. In this embodiment, the first adapter wire 6 is used for applying pressure to the CVT. The specific type of the first adapter wire 6 can be set according to actual needs and is not limited thereto. For example, the first adapter wire 6 is a wire structure and can be stretched and extended using structures such as spirals to adapt to the movement of the lifting device 3 and the first rotary telescopic device 4.

[0027] In some embodiments, the lifting device 3 includes: a first bracket, a first lead screw, a first slide block, and a first motor. The first bracket is vertically mounted on the base 1, and the first lead screw is rotatably mounted on the first bracket. The first slide block is vertically slidably mounted on the first bracket and serves as the lifting end of the lifting device 3. The first slide block and the first lead screw are threadedly connected. The first motor is mounted on the base 1, and the power output end of the first motor is connected to the power input end of the first lead screw. The first motor drives the first lead screw to rotate, and the signal input end of the first motor is connected to the signal output end of the control module 2.

[0028] It is understandable that, since the first bracket is vertically mounted on the base 1, and the first lead screw is rotatably mounted on the first bracket, and the first slide is vertically slidably mounted on the first bracket, and the first slide and the first lead screw are connected by a threaded transmission, when the first lead screw rotates, it can drive the first slide to move vertically on the first bracket, thereby realizing the vertical position adjustment of the first hook 5 on the first rotary telescopic device 4.

[0029] Furthermore, since the power output end of the first motor is connected to the power input end of the first lead screw, and the signal input end of the first motor is connected to the signal output end of the control module 2, the control module 2 can control the first motor to drive the first lead screw to rotate, thereby facilitating the automatic hooking operation of the first hook 5.

[0030] It should be noted that the first support is used to support the first lead screw, the first slide, etc. The specific type of the first support can be set according to actual needs and there is no restriction. For example, the first support is a frame structure and is set vertically on the column of the base 1.

[0031] The first lead screw and the first slide are used to convert the rotational motion of the first motor into linear motion. The specific types of the first lead screw and the first slide can be set according to actual needs and are not limited thereto. For example, the first lead screw is rotatably mounted on the first bracket using a bearing, and the first slide is slidably mounted on the first bracket using a guide rail. The first lead screw and the first slide are threadedly connected.

[0032] The first motor drives the first lead screw to rotate under the control of the control module 2, thereby realizing the lifting function of the lifting device 3. The specific type of the first motor can be set according to actual needs and is not limited thereto.

[0033] Among them, the outer periphery of the lifting device 3 can be equipped with an insulating outer sheath, which completely eliminates the risk of electric shock from the aspects of human protection and machine protection. It is suitable for 500kV high voltage environment and meets the needs of 500kV line outgoing CVT test to hang high voltage pressurization line and discharge grounding line multiple times.

[0034] In some embodiments, the first rotary telescopic device 4 includes a rotary mechanism and a telescopic mechanism. The rotary mechanism is located at the lifting end of the lifting device 3, and the telescopic mechanism is located at the rotary end of the rotary mechanism. The first hook 5 is located at the telescopic end of the telescopic mechanism. The rotary mechanism drives the telescopic mechanism to rotate vertically, and the telescopic mechanism drives the first hook 5 to extend and retract horizontally. The signal output terminal of the control module 2 is connected to the signal input terminals of the rotary mechanism and the telescopic mechanism, respectively.

[0035] It is understandable that, since the rotating mechanism is located at the lifting end of the lifting device 3 and the telescopic mechanism is located at the rotating end of the rotating mechanism, and the first hook 5 is located at the telescopic end of the telescopic mechanism, the first hook 5 can rotate vertically using the rotating mechanism and extend horizontally using the telescopic mechanism. Furthermore, since the signal output terminal of the control module 2 is connected to the signal input terminal of the rotating mechanism and the signal input terminal of the telescopic mechanism respectively, the control module 2 can control the rotating mechanism and the telescopic mechanism, thereby realizing the horizontal position adjustment of the first hook 5.

[0036] It should be noted that the rotating mechanism is used to drive the telescopic mechanism to rotate vertically, and the telescopic mechanism is used to drive the first hook 5 to extend and retract horizontally. Through the cooperation of the two, the position of the first hook 5 in the horizontal direction can be adjusted. The specific types of the rotating mechanism and the telescopic mechanism can be set according to actual needs, and there are no restrictions on them.

[0037] In some embodiments, the telescopic mechanism includes: a second bracket, a second lead screw, a second slide block, an extension rod, and a second motor. The second bracket is horizontally positioned at the rotating end of the rotating mechanism, and the second lead screw is rotatably mounted on the second bracket. The second slide block is horizontally slidably mounted on the second bracket, and the second slide block and the second lead screw are threadedly connected. One end of the extension rod is mounted on the second slide block, and the end of the extension rod away from the second slide block extends horizontally and serves as the telescopic end of the telescopic mechanism. A first hook 5 is mounted on the end of the extension rod away from the second slide block. The second motor is mounted on the second bracket, and the power output end of the second motor is connected to the power input end of the second lead screw. The second motor drives the second lead screw to rotate, and the signal input end of the second motor is connected to the signal output end of the control module 2.

[0038] It is understandable that, since one end of the extension rod is set on the second slide, and the end of the extension rod away from the second slide extends horizontally, the first hook 5 is set on the end of the extension rod away from the second slide, so that the first hook 5 can be set on the second slide using the extension rod.

[0039] Furthermore, since the second bracket is set horizontally at the rotating end of the rotating mechanism, and the second lead screw is rotatably mounted on the second bracket, and the second slide is slidably mounted on the second bracket in the horizontal direction, and the second slide and the second lead screw are connected by a threaded drive, when the second lead screw rotates, it can drive the second slide to move vertically on the second bracket, thereby realizing the horizontal position adjustment of the first hook 5 on the extension rod.

[0040] In addition, since the power output end of the second motor is connected to the power input end of the second lead screw, and the signal input end of the second motor is connected to the signal output end of the control module 2, the control module 2 can control the second motor to drive the second lead screw to rotate, thereby facilitating the automatic hooking operation of the first hook 5.

[0041] It should be noted that the second support is used to support the second lead screw, the second slide, etc. The specific type of the second support can be set according to actual needs and there is no restriction. For example, the second support is a frame structure, which is set horizontally at the rotating end of the rotating mechanism. Alternatively, it can be rotatably arranged on the first support using a slewing bearing or the like, and driven to rotate by the rotating mechanism.

[0042] The second lead screw and the second slide are used to convert the rotational motion of the second motor into linear motion. The specific types of the second lead screw and the second slide can be set according to actual needs and are not limited thereto. For example, the second lead screw is rotatably mounted on the second bracket using a bearing, and the second slide is slidably mounted on the first bracket using a guide rail. The second lead screw and the second slide are threadedly connected.

[0043] The extension rod is used to extend the first hook 5 from the second slide. The specific type of the extension rod can be set according to actual needs and is not limited thereto. For example, the extension rod is an insulating rod. The first adapter line 6 passes around or through the extension rod and is connected to the first hook 5.

[0044] The second motor drives the second lead screw to rotate under the control of the control module 2 to achieve the telescopic function. The specific type of the second motor can be set according to actual needs and is not limited thereto.

[0045] In some embodiments, the rotating mechanism includes a third motor and a reducer. The third motor and the reducer are respectively disposed at the lifting end of the lifting device 3, and the power output end of the third motor is connected to the power input end of the reducer. The power output end of the reducer serves as the rotating end of the rotating mechanism and rotates vertically. A telescopic mechanism is disposed at the power output end of the reducer, and the signal output end of the control module 2 is connected to the signal input end of the third motor.

[0046] It is understandable that, since the power output end of the third motor is connected to the power input end of the reducer, and the telescopic mechanism is located at the power output end of the reducer, the signal output end of the control module 2 is connected to the signal input end of the third motor, enabling the control module 2 to control the third motor to drive the power output end of the reducer to rotate vertically, thereby driving the telescopic mechanism and the first hook 5 on the telescopic mechanism to rotate, thus facilitating the adjustment of the position of the first hook 5 in the horizontal direction.

[0047] It should be noted that the third motor and reducer are used in conjunction to achieve the rotation of the telescopic mechanism. The specific types of the third motor and reducer can be set according to actual needs and are not limited thereto. Specifically, the power output end of the reducer drives the second bracket to rotate vertically.

[0048] like Figure 1 and Figure 2As shown, in some embodiments, the mounting system further includes: a second rotary telescopic device 7, a second hook 8, and a second adapter wire 9. The second rotary telescopic device 7 is located at the lifting end of the lifting device 3 and forms a preset angle with the first rotary telescopic device 4 in the horizontal direction. The lifting device 3 drives the second rotary telescopic device 7 to move vertically. The second hook 8 is located at the rotary telescopic end of the second rotary telescopic device 7, and the second rotary telescopic device 7 drives the second hook 8 to rotate vertically and extend horizontally. The first end of the second adapter wire 9 is located on the base 1, and the second end of the second adapter wire 9 is connected to the second hook 8. The control module 2 drives the lifting device 3 and the second rotary telescopic device 7 to mount the second hook 8 at the target position of the capacitive voltage transformer 100. The first end of the first adapter wire 6 is used to connect to a pressure testing device, and the first end of the second adapter wire 9 is used to connect to a grounding network.

[0049] Understandably, since the second rotary telescopic device 7 is located at the lifting end of the lifting device 3, and the second hook 8 is located at the rotary telescopic end of the second rotary telescopic device 7, the second hook 8 can be mounted on the base 1 using the lifting device 3 and the second rotary telescopic device 7. Furthermore, it can move vertically using the lifting device 3 and horizontally using the second rotary telescopic device 7. Simultaneously, since the signal output terminal of the control module 2 is connected to the signal input terminal of the lifting device 3 and the signal input terminal of the second rotary telescopic device 7 respectively, the control module 2 can control the lifting device 3 and the second rotary telescopic device 7, thereby achieving the mechanized adjustment of the spatial position of the second hook 8. This allows the second hook 8 to be efficiently and safely attached to the target position of the capacitive voltage transformer 100, achieving a reliable CVT test.

[0050] The first hook 5 is used for pressurization during the CVT test, and the second hook 8 is used for discharge after the CVT test.

[0051] It should be noted that the second rotary telescopic device 7, the second hook 8, and the second adapter cable 9, together with the first rotary telescopic device 4, the first hook 5, and the first adapter cable 6, are used to achieve pressurization and discharge in the CVT test.

[0052] The specific types of the second rotary telescopic device 7, the second hook 8, and the second adapter cable 9 can be set according to actual needs and are not limited thereto. For example, the second rotary telescopic device 7 and the first rotary telescopic device 4 have the same structure, the second hook 8 and the first hook 5 have the same structure, and the second adapter cable 9 and the first adapter cable 6 have the same structure.

[0053] In a specific operation, for example, the lifting device 3 is raised, and the first rotating telescopic device 4 is controlled to rotate and extend the first hook 5 to directly above the target bolt. Then, the lifting device 3 is lowered, thereby enabling the first hook 5 to engage with the target bolt, and then the pressurization operation for the CVT test is carried out. Afterwards, the lifting device 3 is raised again, enabling the first hook 5 to disengage from the target bolt.

[0054] Similarly, the lifting device 3 is raised, and the second rotating telescopic device 7 is controlled to rotate and extend the second hook 8 to directly above the target bolt. Then, the lifting device 3 is lowered, thereby enabling the second hook 8 to engage with the target bolt, and then the discharge operation for the CVT test is performed. Afterward, the lifting device 3 is raised again, enabling the second hook 8 to disengage from the target bolt.

[0055] like Figure 1 and Figure 2 As shown, in some embodiments, the mounting system further includes: a first terminal 10 and a second terminal 11. The first terminal 10 is disposed on the base 1 and is connected to the first end of the first adapter cable 6. The first terminal 10 is used to connect to the pressure testing equipment. The second terminal 11 is disposed on the base 1 and is connected to the first end of the second adapter cable 9. The second terminal 11 is used to connect to the grounding network.

[0056] It is understandable that, since the first terminal 10 is set on the base 1 and the first terminal 10 is connected to the first end of the first adapter cable 6, the first adapter cable 6 can be easily connected to the pressure test equipment by using the first terminal 10, making the CVT test operation more efficient and stable.

[0057] Since the second terminal 11 is set on the base 1 and the second terminal 11 is connected to the first end of the second adapter cable 9, the second adapter cable 9 can be easily connected to the grounding network using the second terminal 11, making the CVT test operation more efficient and stable.

[0058] It should be noted that the first terminal 10 is used to connect the pressure test equipment, and the second terminal 11 is used to connect the grounding network. The specific types of the first terminal 10 and the second terminal 11 can be set according to actual needs and there are no restrictions on this. For example, the first terminal 10 and the second terminal 11 can be conductive column structures, and the wires can be connected to the conductive columns by winding, screw fixing, etc.

[0059] like Figure 1 and Figure 2As shown, in some embodiments, the control module 2 includes a control unit 21 and multiple control buttons 22. The control unit 21 is disposed within the base 1, and its signal output terminal is connected to the signal input terminal of the lifting device 3 and the signal input terminal of the first rotary telescopic device 4, respectively. Multiple control buttons 22 are connected to the signal input terminals of the control unit 21, and the control buttons 22 are used to input control commands to the control unit 21. The control unit 21 is used to control the lifting device 3 and the first rotating telescopic device 4 according to the control commands, so that the first hook 5 is attached to the target position of the capacitive voltage transformer 100.

[0060] It is understandable that since the signal output terminal of the control unit 21 is connected to the signal input terminal of the lifting device 3 and the signal input terminal of the first rotating telescopic device 4 respectively, and multiple control buttons 22 are connected to the signal input terminal of the control unit 21 respectively, the control buttons 22 can input control commands to the control unit 21, thereby enabling the control unit 21 to control the lifting device 3 and the first rotating telescopic device 4 according to the control commands, and thus enabling the first hook 5 to be hooked at the target position of the capacitive voltage transformer 100.

[0061] It should be noted that among the multiple control buttons 22, there are not only buttons for controlling the action of the first hook 5, but also buttons for controlling the action of the second hook 8.

[0062] For example, some control buttons 22 can control the lifting device 3 to lift, some control buttons 22 can control the rotating mechanism to rotate, and some control buttons 22 can control the telescopic mechanism to extend and retract.

[0063] The control unit 21 can be a controller, control panel, etc., and there are no restrictions on it.

[0064] like Figure 1 and Figure 2 As shown, in some embodiments, the mounting system further includes: a voltage testing device 12, which is mounted on the base 1 and has its voltage testing end connected to the first adapter cable 6. The voltage testing device 12 is used to detect the voltage of the first adapter cable 6 and to issue a warning message when the voltage of the first adapter cable 6 exceeds a preset voltage value.

[0065] Understandably, since the voltage testing terminal of the voltage testing device 12 is connected to the first adapter cable 6, the voltage testing device 12 can detect the voltage of the first adapter cable 6. Furthermore, when the voltage of the first adapter cable 6 exceeds the preset voltage value, the voltage testing device 12 issues a warning message to alert the operator and reduce the risk of electric shock.

[0066] like Figure 1 and Figure 2As shown, in some embodiments, the voltage detection device 12 includes: a voltage detector 121, a live indicator light 122, an audible alarm 123, and a battery (not shown). The voltage detector 121 is housed within the base 1, and its detection terminal is connected in series with the first adapter cable 6. The signal input terminals of the live indicator light 122 and the audible alarm 123 are respectively connected to the signal output terminal of the voltage detector 121. The voltage detector 121 controls the live indicator light 122 to emit a light warning signal and the audible alarm 123 to emit an audible warning signal when the voltage of the first adapter cable 6 exceeds a preset voltage value. The power output terminal of the battery is connected to the power input terminals of the voltage detector 121, the live indicator light 122, and the audible alarm 123.

[0067] Understandably, since the voltage detection terminal of the voltage detector 121 is connected in series with the first adapter cable 6, and the signal input terminals of the live indicator light 122 and the sound alarm 123 are respectively connected to the signal output terminal of the voltage detector 121, the voltage detector 121 can detect the voltage on the first adapter cable 6, and when the voltage on the first adapter cable 6 exceeds the preset voltage value, it controls the live indicator light 122 to emit a light warning message and controls the sound alarm 123 to emit a sound warning message, thereby effectively alerting the workers through sound and light, reducing the risk of electric shock.

[0068] In addition, since the power output terminal of the storage battery is connected to the power input terminal of the voltage detector 121, the power input terminal of the live indicator light 122, and the power input terminal of the audible alarm 123 respectively, the storage battery can supply power to the voltage detector 121, the live indicator light 122 and the audible alarm 123 respectively, thereby ensuring the stable operation of the voltage detector 12.

[0069] It should be noted that the voltage detector 121 is used for voltage detection and control of the live indicator light 122 and the sound alarm 123. The specific type of voltage detector 121 can be set according to actual needs and is not limited thereto. For example, the voltage detector 121 can be a voltage detection circuit that can control the live indicator light 122 and the sound alarm 123, or it can be an integrated module of voltage sensor and microcontroller.

[0070] The storage battery is used to power the voltage detector 121, the live indicator light 122, and the audible alarm 123. The specific type of storage battery can be set according to actual needs and is not limited thereto. For example, the storage battery can be a rechargeable battery.

[0071] The key feature of the mounting system in this embodiment lies in the precise application of the mechanical hydraulic lifting mechanism. This system optimizes the structural design of the mounting wire in the 500kV line outgoing CVT test process, improving operational efficiency. The discharge device adopts automated control to ensure the safety of the discharge process and eliminate contact between personnel and live equipment. Secondly, the lifting mechanism of the mounting system in this embodiment embeds a first voltage output adapter 6 and a second discharge grounding adapter 9. The outer sheath is made of insulating material, completely eliminating the risk of electric shock from both personnel and machine protection perspectives. It is suitable for 500kV high-voltage environments and meets the requirement of multiple high-voltage pressurization lines and discharge grounding lines in the 500kV line outgoing CVT test. At the same time, the voltage output test line of the mounting system in this embodiment is equipped with a voltage detection device 12 in series at the end. The 500kV line outgoing CVT test mounting wire and discharge device also have a voltage detection function.

[0072] Furthermore, it should be noted that the connection system in this embodiment is based on the actual situation of power production and takes into account all aspects of high-voltage electrical preventive testing. First, this patented technology can be widely applied to the connection and discharge operations of CVT test lines at multiple voltage levels, such as 500kV, 220kV, and 110kV systems. It solves the problems of high installation height of 500kV line outgoing CVTs, where personnel stand on the ground and use insulating rods to connect the test lines to the flange bolts of each section, resulting in blind spots, inconvenient observation, and unstable connection.

[0073] Secondly, the connection terminal interface of the system in this embodiment is convenient and highly expandable, with replaceable experimental wiring, and can also perform functions such as voltage detection and discharge. This means that the device can be widely used for preventive testing of power systems, such as main transformers, engines, and surge arresters. In different application scenarios, the test wiring and methods can be adjusted according to actual needs to better suit the actual situation, avoiding the high risk of personnel discharge after 500kV line outgoing CVT testing, the risk of arcing due to improper discharge operation, and the risk of personal injury due to improper grounding.

[0074] In summary, the mounting system of this embodiment, through its precise lifting and steering mechanisms and rich interface design, provides a strong guarantee for the safe and efficient conduct of preventive CVT tests on 500kV line outgoing lines, and also provides more options for electrical preventive testing methods.

[0075] In summary, the mounting system of this embodiment has at least the following advantages: The device involves a test connection and discharge operation device for a 500kV line outgoing CVT. It will use a drive motor and a lifting device 3 to achieve directional adjustment at any height and angle. A test hook will be installed at the top to connect to the flanges of the upper, middle and lower sections of the 500kV line outgoing CVT with bolts, which will facilitate connection and discharge operations at different test positions during the test.

[0076] It can be widely used in CVT test connection and discharge operations for multiple voltage levels such as 500kV system, 220kV system and 110kV system. It solves the problems of high installation height of 500kV line outgoing CVT, inconvenience for personnel to stand on the ground and use insulating rods to hang the test line to the flange bolts of each section for observation, and unstable connection. At the same time, it also avoids the high risk of personnel discharge after 500kV line outgoing CVT test, the easy arcing caused by improper discharge operation, and the easy personal injury accident caused by improper grounding.

[0077] It has two terminals, providing a variety of wiring options to meet different working conditions.

[0078] It adopts a 220V power supply, which has good voltage compatibility and is convenient for power supply and daily maintenance.

[0079] It features a power switch and some function buttons, has a compact appearance, and adopts a modular assembly installation method, making it easy to install and disassemble.
