Description

Technical Field

[0001] The utility model relates to the field of electric power equipment, in particular to a high-voltage electrical tester. Background Art

[0002] As an indispensable safety detection tool in the power industry, high-voltage testers are widely used in power grid companies, power plants, railways, metallurgy, chemical industry, petroleum and other enterprises involving high-voltage electricity operations. They are mainly used to detect whether high-voltage equipment such as power lines, transformers, and various switch cabinets are energized.

[0003] However, traditional high-voltage testers have exposed some obvious limitations and safety hazards in actual use. When conducting long-distance electrical testing at high altitudes outdoors, signal feedback is limited to the operator himself, and guardians and other work members cannot know the test results in real time, reducing the safety and efficiency of team collaboration. In addition, the sound and light alarm device of the traditional tester is located at the end of the insulating pole. For long-pole electrical testing, the alarm signal is easily affected by distance attenuation, especially in strong light or noisy environments outdoors. The operator's hearing and visual sensitivity decreases, which may cause the alarm signal to be ignored, increasing the risk of misjudgment.

[0004] In view of the above problems, there is an urgent need to provide a high-voltage tester with a multi-point proximal alarm function to overcome the limitations of traditional equipment and improve the safety and accuracy of the test process. Utility Model Content

[0008] As an improvement of the above scheme, it also includes a pair of protective shells, magnets, transparent plates, connecting rods and torsion springs; a pair of protective shells are symmetrically sleeved on the front end of the insulating rod body, and each protective shell is equipped with a magnet, which attracts each other through magnetic force to achieve closed fixation: the transparent plate is embedded in the middle of each protective shell, allowing the electrician to still observe the status of the internal metal contacts in the closed state; multiple connecting rods are fixedly connected to the two side surfaces of the insulating rod body, and form a rotational connection with the protective shell; each connecting rod is sleeved with a torsion spring, which is used to automatically reset the protective shell to the closed state after it is opened, providing additional safety protection.

[0009] As an improvement of the above scheme, a sleeve is also included; the sleeve is sleeved on the connecting rod, and the torsion spring is placed inside the sleeve, forming an effective protection for the torsion spring.

[0010] As an improvement of the above solution, it also includes a waterproof pad and an elastic drawstring; the waterproof pad is specially designed to wrap the metal contact to provide waterproof and dustproof protection; the elastic drawstring is connected between the waterproof pad and one of the protective shells to ensure that the waterproof pad can be fixed on the metal contact.

[0011] As an improvement on the above scheme, it also includes an air intake cylinder, a one-way valve, an exhaust valve, a hollow telescopic rod, a sealing slider and a connecting block; there are three hollow telescopic rods in total, which are sequentially connected from small to large to form a telescopic structure, wherein the innermost hollow telescopic rod is fixedly connected to the handle through a connecting block; a sealing slider is fixed to the end of each hollow telescopic rod; the inner walls of the two outer hollow telescopic rods are provided with sliding grooves, allowing the sealing slider to move smoothly therebetween, thereby realizing the extension and contraction of the hollow telescopic rods; the outermost hollow telescopic rod is externally connected with an air intake cylinder; a one-way valve and an exhaust valve are installed at one end of the air intake cylinder to ensure that air can only enter but not flow back, and the exhaust valve is used to control the discharge of air.

[0012] Compared with the prior art, the utility model has the following technical effects: 1. Based on the original wired connection, this device adds a wireless circuit, and uses radio waves to transmit signals to multiple paired wireless module cards, thereby synchronously triggering sound and light alarms at multiple locations, so that team members can instantly perceive the electrical test results no matter where they are, significantly improving the safety and collaborative efficiency of the electrical test process.

[0013] 2. By adding a pair of protective shells to the front end of the insulating rod, an effective protective layer is formed for the metal contacts to prevent them from accidental impact or wear when not in use, thereby extending the service life of the equipment and reducing maintenance costs.

[0014] 3. This device adopts a combination design of an air cylinder, a one-way valve, an exhaust valve, a hollow telescopic rod, a sealed slider, a slide groove and a connecting block to construct an efficient pneumatic telescopic system. When it is necessary to test the electricity at different heights, the insulating rod can be quickly extended and retracted by simply controlling the inflation or deflation, which greatly improves the flexibility and adaptability of the high-voltage tester in a complex working environment.

[0024] See also Figure 1 and Figure 2 A high-voltage electrical tester includes an insulating rod body 1, a metal contact 2, a No. 1 wireless module 3, an audible and visual alarm 4, a handle 6, a protective ring 5, a No. 2 wireless module 7, four searchlights 8 and a start switch 9; the insulating rod body 1 is used as a main support and insulating component; the metal contact 2 is installed at the front end of the insulating rod body 1 for contacting the electrical equipment to be tested; the No. 1 wireless module 3 is embeddedly installed at one end of the insulating rod body 1 close to the metal contact 2, responsible for collecting high-voltage electricity information and converting it into a transmittable signal; the audible and visual alarm 4 is also embeddedly installed near the front end of the insulating rod body 1, receives the signal from the built-in circuit, and triggers the local audible and visual alarm; the handle 6 is set at the insulating rod The rear end of the insulating rod body 1 is convenient for the operator to hold the insulating rod body 1; the protective ring 5 is sleeved between the handle 6 and the insulating rod body 1 to provide additional insulation protection and comfort of holding; the second wireless module 7 is installed at the rear end of the insulating rod body 1, located in front of the protective ring 5, and is used to transmit signals like the first wireless module 3, and establishes a Bluetooth wireless connection with the external main wireless module card; four searchlights 8 are installed around the front end of the insulating rod body 1 to provide centralized lighting, ensuring that the electrician can still clearly observe the contact status of the metal contacts and electrical equipment under dim conditions; the starting switch 9 is set in the middle position of the insulating rod body 1, which is easy for the operator to reach, and is used to control the opening and closing of the searchlight 8.

[0025] Before the electricity test, the preset wireless module cards are distributed to the guardians and working members on site to ensure that each person holds one. During the electricity test, when the metal contact 2 measures the high voltage on the electrical equipment, the collected high voltage information is converted into a low voltage level signal through the built-in circuit. This signal is first transmitted to the sound and light alarm 4 through a wired connection, triggering the local alarm of the sound and light alarm 4, and then the signal is sent to all paired wireless module cards through the No. 1 wireless module 3 and the No. 2 wireless module 7 in a Bluetooth wireless manner. After the wireless module cards in the hands of the guardians and working members receive the signal, they immediately trigger the sound and light alarm on their respective portable devices to realize multi-point sound and light alarm linkage. This design makes the electricity test operation no longer limited to the perception of a single operator, but realizes "one-point electricity test, multi-person perception", which significantly improves the safety and accuracy of the electricity test process and effectively reduces the risk of misjudgment.

[0026] Example 2

[0027] Based on Example 1, please refer to Figure 2 and Figure 3 , also includes a pair of protective shells 10, a magnet 11, a transparent plate 12, a connecting rod 13, a torsion spring 14, a sleeve 15, a waterproof pad 16 and an elastic pull rope 17; a pair of protective shells 10 are symmetrically sleeved on the front end of the insulating rod body 1, each protective shell 10 is equipped with a magnet 11, and they are attracted to each other by magnetic force to achieve closed fixation: the transparent plate 12 is embedded in the middle of each protective shell 10, allowing the electrician to still observe the state of the internal metal contact 2 in the closed state; two connecting rods 13 symmetrically distributed in the upper and lower directions are fixedly connected to the left and right sides of the insulating rod body 1, and are rotatably connected to the protective shell 10; each connecting rod 13 The upper sleeve is provided with a torsion spring 14, which is used to automatically reset the protective shell 10 to a closed state after it is opened, providing additional safety protection; a sleeve 15 is provided on the connecting rod 13, and the torsion spring 14 is placed inside the sleeve 15, forming an effective protection for the torsion spring 14; the waterproof pad 16 is specially designed to wrap the metal contact 2, providing waterproof and dustproof protection, and preventing the metal contact 2 from being corroded by moisture or dust during storage or transportation, thereby extending the service life of the equipment; the elastic draw cord 17 is connected between the waterproof pad 16 and one of the protective shells 10 to ensure that the waterproof pad 16 can be fixed on the metal contact 2 for easy removal.

[0028] After completing the electrical testing operation, the operator can manually rotate the two protective shells 10 to the front end of the insulating rod 1, and use the attraction of the magnet 11 to make the two protective shells 10 fit tightly together to form a protective cover to prevent the metal contacts 2 from being accidentally impacted or worn when not in use. When it needs to be used again, simply pull open the protective shell 10, and the built-in torsion spring 14 will automatically assist the protective shell 10 to reset to its initial position, so as to quickly prepare for the next electrical testing task.

[0029] See also Figure 4 , Figure 5 and Figure 6, also includes an air intake cylinder 18, a one-way valve 19, an exhaust valve 20, a hollow telescopic rod 21, a sealing slider 22 and a connecting block 24; there are three hollow telescopic rods 21, which are connected in sequence from small to large to form a telescopic structure, wherein the innermost hollow telescopic rod 21 is fixedly connected to the handle 6 through a connecting block 24; a sealing slider 22 is fixed to the end of each hollow telescopic rod 21; the inner walls of the two outer hollow telescopic rods 21 are provided with a slide groove 23, allowing the sealing slider 22 to move smoothly therebetween, thereby realizing the extension and contraction of the hollow telescopic rod 21; the outermost hollow telescopic rod 21 is externally sleeved with an air intake cylinder 18; a one-way valve 19 and an exhaust valve 20 are installed at one end of the air intake cylinder 18 to ensure that air can only enter but not flow back, and the exhaust valve 20 is used to control the discharge of air, and by inflating the air intake cylinder and using the gas pressure to push the sealing slider to move along the slide groove, the hollow telescopic rod can be extended step by step.

[0030] When the operator needs to test the electricity at a higher position, he only needs to inflate the air inlet cylinder 18. Under the action of the one-way valve 19, the gas can only flow forward and enter the hollow telescopic rod 21, pushing the sealing slider 22 to move along the slide groove 23. As the gas pressure accumulates, the first (smallest) hollow telescopic rod 21 is extended first, followed by the second, and finally the third (largest), to achieve the overall extension of the insulating rod body 1. After reaching the required height, the inflation is stopped. Finally, after the electrical test is completed, the operator can control the exhaust valve 20 to slowly release the gas to smoothly retract the telescopic rod, ensuring that the entire operation process is safe and controllable.
