Description

Technical Field

[0001] The invention relates to the technical field of electrical safety, and in particular to an automatically extending high-voltage electrical testing device. Background Art

[0002] A high-voltage tester is a special safety tool used to detect whether electrical equipment or lines carry high voltage electricity. Its principle is mainly based on electric field induction and charge conduction. When the tester is close to a charged object, the electric field induction causes the tester probe to induce a charge, thereby generating an electrical signal; for a contact tester, when the probe contacts the charged object, the charge is conducted to the indicator device inside the tester. These indicator devices usually include neon tubes, light-emitting diodes (LEDs), etc., which will emit light when receiving a charge signal, and may also be accompanied by a buzzer sound, so as to intuitively show that the object being tested is charged. In the daily inspection of substations, staff need to use high-voltage testers to conduct live detection of various high-voltage equipment (such as transformers, circuit breakers, disconnectors, etc.). Through the indication of the tester, it is possible to quickly and accurately determine whether the equipment is energized, which is crucial for timely discovering potential electrical safety hazards, preventing electric shock accidents, and ensuring the stable operation of the power system.

[0003] The existing high-voltage tester consists of three parts: the detection part (indicator part or windmill), the insulation part, and the handle part. The insulation part refers to the part from the metal connection screw at the bottom of the indicator to the cover guard ring, and the handle part refers to the part below the cover guard ring. The lengths of the insulation part and the handle part vary according to the voltage level. The current tester requires a lithium battery, and different tester pen tips are required for different voltage levels. When the voltage level is high, it is very heavy and long and cannot be lifted. It is impossible to use a high-voltage tester to measure whether the equipment is energized, which can easily cause short circuit accidents of electrical equipment, resulting in asset losses and personnel risks.

[0034] The technical scheme in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is only a part of the embodiment of the present invention, not all of the embodiments. Based on the embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0036] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0037] In order to solve the problem that when testing whether a high-voltage device is energized, when the voltage level is high, the telescopic rod 2 of the tester is too heavy and long to be lifted, and it is impossible to use the high-voltage tester to measure whether the device is energized, which may easily cause a short circuit accident of the electrical equipment, resulting in asset losses and personnel risks, the present invention provides an automatically extending high-voltage tester, such as Figure 1-Figure 10 As shown, the device includes an electroscope body 1, a telescopic rod 2 and an automatic telescopic device 3. The electroscope body 1 is installed at the top of the telescopic rod 2. The adjustable length of the telescopic rod 2 can realize the measurement requirements of different heights. When dealing with the detection of equipment with low voltage level, only the length of the telescopic rod 2 can meet the requirements of electrical testing of the equipment outside the safe distance. The telescopic rod 2 is light and insulated; when the voltage level of the live equipment with high voltage level is measured, the telescopic rod 2 can be detachably installed on the automatic telescopic device 3, and the automatic telescopic device 3 can automatically adjust the distance during operation. The automatic telescopic device 3 is installed outside the safe distance of the high-voltage equipment, and there is no need to approach the high-voltage source during operation to ensure the safety of the detection personnel. The automatic telescopic device 3 can accurately control the length of the telescopic rod 2, so that the electroscope body 1 is always in the best measurement position, avoiding the inconvenience of operation and measurement errors caused by the excessive safety distance. The electroscope adopts a modular and detachable design as a whole, which is convenient for flexible application, carrying and maintenance. At the same time, it solves the problem that when the voltage level is high, the telescopic rod 2 of the electroscope is very heavy and long, and the staff cannot lift it so that the test cannot be carried out.

[0038] In a preferred embodiment, the automatic telescopic device 3 is composed of a base 301, a mounting seat 302 and a telescopic assembly. The base 301 is fixedly mounted outside the safety distance of the high-voltage equipment to be tested and grounded to ensure that the entire device is away from the high-voltage power supply during operation, and to provide stable support and avoid accidental contact with the high-voltage area. A mounting seat 302 is provided above the base 301, and the mounting seat 302 is mounted on the base 301 by rotation, so as to facilitate the telescopic assembly to be turned to a safe position so as to facilitate the installation of the telescopic rod 2 on the telescopic assembly. The telescopic assembly is mounted on the mounting seat 302, and the telescopic rod 2 connected to the electroscope body 1 is detachably connected to the telescopic assembly. The telescopic length and horizontal angle are adjusted by the precise telescopic assembly to achieve the measurement of high-voltage equipment at different heights and distances. The design of the automatic telescopic device 3 ensures that the electroscope body 1 is always in a safe and appropriate detection position, and effectively prevents the staff from being unable to lift the telescopic rod 2 due to the safety distance being too long or the angle being not good. The structure of the entire device not only facilitates the rapid adjustment and positioning of the equipment, but also facilitates subsequent maintenance and maintenance, improves the safety of the staff, and is suitable for the inspection of high-voltage power facilities in complex outdoor environments, ensuring safety and convenient operation.

[0039] In a preferred embodiment, the mounting seat 302 structure includes a rotating disk 3021 and a connecting seat 3022. The base 301 is a cylindrical rod, and a rotating hole is set at the top of the base 301. The rotating disk is a disc-shaped base, and a rotating member is set at the lower part of the base. The rotating disk is rotatably mounted at the rotating hole of the base 301 through the rotating member. The connecting seat 3022 is a right-angle T-shaped design with a solid structure. The right-angle side of the connecting seat 3022 is fixed to the upper part of the rotating disk 3021 by welding. The design of the rotating disk 3021 enables the mounting seat 302 to achieve horizontal rotation on the base 301, which is convenient for turning the telescopic assembly to a safe position so as to facilitate the installation of the telescopic rod 2 on the telescopic assembly. The long side of the connecting seat 3022 is provided with a first connecting hole 3023, and the short side is provided with a second connecting hole 3024, which provides installation points for different components of the telescopic assembly.

[0040] The telescopic assembly includes multiple components such as a motor 307, a fixed sleeve 304, a slide rod 306, a linear cylinder 305, a screw 308 and a screw nut 309, and realizes a stable telescopic function and an angle adjustment function through precise matching. A first connecting piece 3043 is provided at the tail of the fixed sleeve 304, on which a connecting hole is provided, which is used to rotatably connect with the first connecting hole 3023 of the connecting seat 3022, so as to allow the fixed sleeve 304 to adjust the angle on the connecting seat 3022. A second connecting piece 3044 is provided at the lower side of the middle part of the fixed sleeve 304, and the linear cylinder 305 is rotatably mounted at the second connecting hole 3024 of the connecting seat 3022 and its piston rod is rotatably mounted on the second connecting piece 3044 of the fixed sleeve 304. This structure enables the telescopic action of the linear cylinder 305 to flexibly adjust the angle and position of the fixed sleeve 304, thereby adapting to the measurement requirements of different heights, and at the same time, a stable triangular structure can be formed to provide support for the fixed sleeve 304.

[0041] The slide bar 306 is installed in the fixed sleeve 304 and can slide freely therein. The slide bar 306 is fixedly provided with a screw nut 309 at one end close to the connecting seat 3022, and the extension and contraction of the slide bar 306 is controlled by cooperating with the screw 308. A mounting hole 3041 is designed at the bottom of the fixed sleeve 304, and one end of the screw 308 is rotatably mounted on the bottom of the fixed sleeve 304 through the mounting hole 3041, ensuring that the screw 308 rotates stably in the fixed sleeve 304. At the same time, a driving motor 307 is installed at the bottom of the fixed sleeve 304, and the motor 307 directly drives the rotation of the screw 308 through a transmission connection, so that the slide bar 306 performs a stable extension and contraction movement in the fixed sleeve 304. The cooperation of the screw nut 309 and the screw 308 ensures that the slide bar 306 can achieve high-precision extension and contraction control under the drive of the motor 307, so that the staff is away from high-voltage live equipment, and the stability and safety of the measurement process are ensured.

[0042] In addition, the structural design of the fixed sleeve 304 and the slide rod 306 also fully considers the stability of outdoor applications. The shell 303 is made of high-strength anti-corrosion insulating material, which can adapt to the power facility detection needs of different environments, especially in high humidity or dusty conditions outdoors, and can still maintain stable operating performance.

[0043] This structure not only allows workers to stay away from high-voltage live equipment and keep themselves safe, but also maintains high operational flexibility and stability. The stable installation of the base 301, the rotation function of the mounting seat 302, and the multiple adjustment mechanisms of the telescopic assembly jointly ensure the safety and accuracy of the measurement process. The design of the entire device fully considers the complex needs in the power detection environment. By fixing the base 301 and rotating the mounting seat 302, when it is set in a suitable position, it can flexibly respond to measurement tasks of different heights, angles and positions for multiple devices.

[0044] In a preferred embodiment, a protective shell is provided at the bottom of the fixed sleeve 304, which further improves the safety and durability of the device. The protective shell is tightly mounted at the bottom of the fixed sleeve 304, and the motor 307 is fully covered inside it, forming an effective protective barrier. The protective shell can not only prevent the motor 307 from being directly affected by the external environment, such as erosion by dust, rain and other external impurities, but also reduce the vibration and impact of the motor 307 during operation, thereby extending the service life of the motor 307. The material of the protective shell is selected from metal or weather-resistant plastic with high strength and corrosion resistance to ensure that the device can operate stably in various harsh environments, and is particularly suitable for the complex environment of outdoor high-voltage equipment testing.

[0045] In a preferred embodiment, a limiting slide groove 3042 is provided inside the fixed sleeve 304, and a limiting slider is correspondingly provided on the slide bar 306. This structure provides precise direction guidance during the extension and retraction process of the slide bar 306, and effectively prevents the slide bar 306 from lateral rotation in the fixed sleeve 304. The limiting slide groove 3042 is provided along the axial direction of the fixed sleeve 304, and cooperates with the limiting slider on the slide bar 306, so that the slide bar 306 can only slide in a straight line along the axial direction of the fixed sleeve 304, and cannot rotate or deviate unnecessarily, thereby ensuring the stability of the slide bar 306.

[0046] In a preferred embodiment, a quick-connect hole 3061 is provided on the slide bar 306, and the quick-connect hole 3061 is axially arranged with the slide bar 306 to ensure the structural stability of the telescopic rod 2 after installation. The length of the quick-connect hole 3061 is consistent with the length of the insulating handle 201 of the telescopic rod 2, so that the insulating handle 201 of the telescopic rod 2 can be fully inserted into the quick-connect hole 3061 to ensure a firm connection, and the insulating handle 201 of the telescopic rod 2 provides insulation protection.

[0047] In order to further ensure the tightness of the telescopic rod 2 and prevent the telescopic rod 2 from rotating in the quick-connect hole 3061, a limiting hole 3062 is carefully arranged on the side wall of the quick-connect hole 3061, and a mounting groove 202 corresponding to the limiting hole 3062 is provided on the insulating handle 201, and an elastic limiting component is installed in the mounting groove 202, so that when the telescopic rod 2 is inserted into the quick-connect hole 3061, the elastic limiting component can automatically dock with the limiting hole 3062 of the quick-connect hole 3061. Specifically, when the insulating handle 201 is inserted into the quick-connect hole 3061, the elastic limiting component will generate a moderate elastic force in the process of sliding into the limiting hole 3062, so that the telescopic rod 2 is automatically stuck and fastened to the slide bar 306. In this way, the telescopic rod 2 can be firmly fixed on the slide bar 306 even in a high-frequency stretching operation, and will not be loose or accidentally fall off.

[0048] This elastic limit design not only enhances the installation convenience of the telescopic rod 2, but also makes it easier to disassemble. The telescopic rod 2 can be quickly removed by pressing or releasing the elastic limit component, thereby improving the disassembly efficiency of the telescopic rod 2. This design is particularly suitable for high-voltage electrical testing devices that are frequently used in complex environments, ensuring that operators can quickly assemble and disassemble the device when performing high-altitude or outdoor operations, shortening the equipment preparation time and reducing safety risks caused by accidental loosening.

[0049] In a preferred embodiment, the elastic limiting component is composed of a limiting block 203 and a spring 204, and the telescopic rod 2 and the slide bar 306 are firmly locked and quickly installed through a clever combination of structures. The limiting block 203 adopts a right-angle T-shaped design, and one side of its long side is fixedly installed in the installation groove 202 to ensure the stable positioning of the limiting block 203 in the groove. The right-angle side is set in the opposite direction of the fixed sleeve 304, which is convenient for accurate matching with the limiting hole 3062 on the slide bar 306 during the connection process, so as to achieve automatic docking and firm locking. The spring 204 is installed between the limiting block 203 and the bottom of the installation groove 202, one end of the spring 204 is fixed at the bottom of the installation groove 202, and the other end is connected to the bottom of the limiting block 203, ensuring that the limiting block 203 is always pushed outward by the elastic force.

[0050] This structural design enables the limit block 203 to have moderate flexibility under the action of the spring 204. When the telescopic rod 2 is inserted into the quick-connect hole 3061 of the slide bar 306, the limit block 203 will temporarily compress the spring 204 and retract it, so that it can smoothly pass through the inner wall of the slide bar 306. Once the limit block 203 is aligned with the limit hole 3062 of the slide bar 306, the spring 204 will quickly restore its elastic force and push the limit block 203 into the limit hole 3062 to achieve automatic locking, ensuring that the telescopic rod 2 is stable and not loose. This elastic limit structure not only enhances the fixing effect of the telescopic rod 2, but also makes the installation and removal of the telescopic rod 2 more convenient. It can be unlocked by pressing the limit block 203.

[0051] In a preferred embodiment, the telescopic component also integrates intelligent electronic components such as a microcontroller module 312, a signal receiving module 313 and an interactive display module 311, which realizes real-time data transmission and interaction, and improves the intelligent and information-based operation of the electroscope. The electroscope body 1 is provided with a data collection module and a signal transmission module, wherein the data collection module is responsible for collecting high-voltage detection data such as voltage and current, and transmitting the information to the signal transmission module. The signal transmission module sends the collected data to the automatic telescopic device 3 in the form of a wireless signal. The microcontroller module 312 and the signal receiving module 313 are installed inside the protective shell, which effectively protects them. The signal receiving module 313 receives the data signal from the electroscope body 1 and transmits it to the microcontroller module 312 for processing. The processed data is then transmitted to the interactive display module 311, which is installed at one end of the protective shell away from the fixed sleeve 304, so that the operator can view the detection results at a safe distance. The interactive display module 311 displays key information such as voltage data and equipment status in real time through a clear and intuitive interface, so that the operator can obtain accurate measurement information without approaching the high-voltage area, ensuring the safety and efficiency of the measurement process.

[0052] In a preferred embodiment, the telescopic component further integrates a sound alarm 310, which adds a real-time safety warning function to the electroscope to prevent the sound and light alarm of the electroscope body 1 from being inconvenient to observe in noisy and high-brightness environments or when the detection distance is too far. The sound alarm 310 is firmly mounted on the protective shell and is electrically connected to the micro-control module 312 to realize an automated safety prompt function. When the data signal of the electroscope body 1 is transmitted to the micro-control module 312 through the signal receiving module 313, the micro-control module 312 not only presents the data on the interactive display module 311, but also performs real-time analysis of the detected data. If the test result shows that the high-voltage equipment is energized, the micro-control module 312 will immediately trigger the sound alarm 310.

[0053] In a preferred embodiment, the protective shell is provided with a plurality of heat dissipation holes 3031 to ensure that the device can maintain good heat dissipation performance during high-intensity use and avoid performance degradation or damage to the device due to overheating. These heat dissipation holes 3031 are evenly arranged on both sides of the shell 303 to ensure that the heat can be evenly distributed and discharged in time. Through this layout, the heat in the shell 303 can be effectively dissipated, especially in long-term operation or in high-temperature environments, avoiding local overheating, and ensuring the stability and long service life of the internal electronic components.

Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention.
