Description

Technical Field

[0002] A tester is a tool used to check whether high-voltage lines and electrical equipment are energized. It is a basic safety tool that checks whether equipment and lines are energized by detecting the current flowing through the stray capacitance between the tester and the ground.

[0003] At present, commonly used electrometers are divided into two categories: 380V and 6KV. When measuring, the electrometer corresponding to the voltage level must be used.

At the same time, after the electrometer is tested on the live equipment, some energy will remain and it cannot discharge by itself. It needs to be manually contacted with a metal conductor to discharge, which poses a safety hazard. Summary of the invention

[0027] The present invention provides the following embodiments

[0028] Example 1

[0029] The embodiment of the present invention provides an electrical testing device, such as Figure 1 As shown, it comprises: a moving seat 1, a driving component 2 is arranged inside the moving seat 1, a lifting component 3 is arranged on the moving seat 1, and an electrical testing component 4 is arranged on the lifting component 3.

[0030] The working principle and beneficial effects of the above technical solution are as follows: the movable seat 1 facilitates the rotation and movement of the electrical testing device, and moves the electrical testing device to a suitable position for electrical testing. The lifting component 3 fixes and limits the electrical testing component 4 while adjusting the height of the electrical testing component 4, thereby adjusting the electrical testing component 4 to a suitable height. The driving component 2 provides power for the lifting action of the lifting component 3. The electrical testing component 4 facilitates the detection of whether the inspected equipment is energized without the need for personnel to directly contact the equipment under test. After the detection is completed, the electrical testing component 4 discharges itself, and there is no need for manual contact with the metal conductor for discharge, thereby eliminating a huge safety hazard.

[0031] Example 2

[0032] On the basis of Example 1, Figure 1-Figure 2As shown, the driving component 2 includes a fixed frame 21, and an air box 22 is provided at the bottom of the fixed frame 21, and an air inlet pipe 23 is provided on the side wall of the fixed frame 21, the air box 22 is connected to the air inlet pipe 23, and an air pipe 25 is provided on the other side of the air box 22, and two layers of filter plates 24 are provided in the air box 22, and an air pump 26 is fixedly provided on the side wall of the fixed frame 21, and the air inlet end of the air pump 26 is connected to the air inlet pipe 25, and the air outlet end of the air pump 26 is connected to the air outlet pipe 27, and an air dividing valve 28 is provided in the top of the fixed frame 21, and the air inlet of the air dividing valve 28 is connected to the air outlet pipe 27, and the two air outlet ends of the air dividing valve 28 are respectively connected to an air dividing pipe 1 281 and an air dividing pipe 2 282, and the air dividing pipe 1 281 and the air dividing pipe 2 282 are respectively connected to the lifting component 3.

[0033] The working principle and beneficial effects of the above technical solution are as follows: the fixed frame 21 supports and fixes the air box 22, and the fixed frame 21 limits and fixes the air inlet pipe 23. The external gas enters the air box 22 from the air inlet pipe 23, and the incoming gas is deeply filtered by the two layers of filter plates 24 in the air box 22 to prevent dust and impurities brought in by the gas from affecting subsequent equipment. The fixed frame 21 fixes the vacuum pump 26, and the vacuum pump 26 generates suction to provide power to inhale gas through the air pipe 25. The inhaled gas enters the air dividing valve 28 through the air outlet pipe 27. The air dividing valve 28 divides the incoming gas into two parts and injects them into the lifting component 3 through the air dividing pipe 1 281 and the air dividing pipe 2 282 respectively, so as to provide power generated by gas for the lifting of the lifting component 3, isolate the electrical testing component 4 in the lifting component 3, and greatly prevent the occurrence of leakage.

[0034] Example 3

[0035] On the basis of Example 2, Figure 1-Figure 2As shown, the lifting assembly 3 includes a lifting frame 31, an insulating layer 32 is provided on the inner wall of the lifting frame 31, an air cavity 33 is opened at the bottom of the lifting frame 31, an air baffle plate 34 is provided on the insulating layer 32, an air baffle plate 35 is provided on the inner wall of the lifting frame 31 above the air baffle plate 34, an air cavity 36 is left between the air baffle plate 34 and the air baffle plate 35, the air distribution pipe 281 is connected to the air cavity 33, and the air distribution pipe 282 is connected to the The air cavity 2 36 is connected, and an air rod 37 is horizontally arranged on the outside of the side wall of the lifting frame 31. A receiving groove 38 is opened on the inner wall of the lifting frame 31. Exhaust valves 341 are respectively arranged on the inner wall of the lifting frame 31 where the air cavity 1 33 is located and on the air baffle plate 1 34. The telescopic end of the air rod 37 passes through the receiving groove 38 and extends into the lifting frame 31. The telescopic end of the air rod 37 is provided with a fixed support 39, and the fixed support 39 has the same shape and size as the receiving groove 38.

[0036] The working principle and beneficial effects of the above technical solution are as follows: the insulating layer 32 isolates the lifting frame 31 from the test component 4 to prevent the power of the test component 4 from leaking through the lifting component 3, resulting in a leakage accident. The insulating layer 32 supports and limits the isolation plate 1 and the isolation plate 2. The gas distribution pipe 1 281 and the gas distribution pipe 2 282 input gas into the air cavity 1 33 and the air cavity 2 36 respectively. The isolation plate 1 is lifted up by the gradually increasing gas in the air cavity 1 33, and the isolation plate 2 is lifted up by the gradually increasing gas in the air cavity 2 36. The lifting of the isolation plate 1 and the isolation plate 2 drives the test component 4 to lift up, and the test component 4 is raised to the preset When it is necessary to descend, open the two exhaust valves 341, and the gas in the air cavity 1 33 and the air cavity 2 36 leaks. The isolation plate 1 and the isolation plate 2 slowly descend under the friction with the insulating layer 32. The test component 4 on the isolation plate 2 descends to the preset test position. After the test component 4 is placed in the lifting frame 31, the output end of the gas rod 37 is extended, and the fixed support 39 on the output end contacts the outer surface of the test component 4 to stably fix the test component 4. When the output end of the gas rod 37 is retracted, the fixed support 39 is inserted into the accommodating groove 38, the test component 4 is released, and then the test component 4 is taken out for replacement and maintenance.

[0038] On the basis of Example 3, Figure 1-Figure 2 As shown, the electrical testing component 4 includes an electrical testing frame 41, in which a rechargeable battery, a capacitor, a voltage transmitter, a self-test module, and a discharge device are arranged. The rechargeable battery, the capacitor, the voltage transmitter, the self-test module, and the discharge device are electrically connected via a DC boost circuit.

[0039] The working principle and beneficial effects of the above technical solution are as follows: the rechargeable battery powers the tester, and the voltage is increased to the corresponding voltage of the tester through the DC boost circuit and the capacitor. After the voltage transmitter shows that the capacitor measurement voltage meets the requirement, the tester can check whether the alarm is correct through the self-test module without direct contact with the live equipment. After the test is completed, the discharge device discharges the capacitor to effectively prevent electric shock accidents.
