Description

Technical Field

[0001] This utility model relates to the technical field of high-voltage disconnector switch contact finger pressure tester equipment, and in particular to an insertable analog contact sensor. Background Technology

[0002] In power systems, the contact pressure of high-voltage switchgear is a critical parameter affecting the conductivity and operational safety of the equipment. For example, insufficient contact pressure in disconnecting switches can lead to poor contact, overheating, or even accidents. Therefore, accurate measurement of contact pressure is essential. Traditional measurement methods suffer from problems such as complex operation and poor adaptability, especially for compact components like insert contacts, making it difficult to achieve rapid and accurate pressure detection.

[0003] In existing technologies, some pressure measurement devices require the replacement of complex clamps for different contact types, and it is difficult to balance the sensor's range and accuracy. For example, in the scenario of measuring the contact pressure of high-voltage disconnect switches, although commonly used strain gauge or clamp-type sensors can cover a certain range, they still have limitations for the narrow gap and high-precision measurement requirements of insert-type contacts.

[0004] Therefore, it is necessary to design an insertable analog contact sensor to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an insertable analog contact sensor. This sensor combines an adjustable clamp structure with the sensor body, aiming to improve the professionalism and efficiency of high-voltage switch contact pressure measurement. It also facilitates the adjustment of the distance between the two clamps, and the adjustment block can be disassembled after adjustment to avoid obstructing subsequent tests.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An insertable analog contact sensor includes a handle, which consists of a cylinder and a rectangular block. The cylinder is fixedly connected to the bottom of the rectangular block. A sensor body is provided at the upper end of the rectangular block. The sensor body and the rectangular block are connected by multiple first bolts. The upper end of the sensor body is provided with two clamps, each of which is provided with multiple first threaded holes. The upper end of the sensor body is provided with multiple second threaded holes. The inner walls of each first threaded hole and each second threaded hole are threaded with a second bolt.

[0008] Preferably, the upper limit of the detection range of the sensor body is N.

[0009] Preferably, the opposite sides of the two clamps are both inclined surfaces, and the two clamps are made of elastic steel sheets.

[0010] Preferably, the upper end of the chuck is provided with an adjustment assembly, the adjustment assembly includes an adjustment block disposed at the upper end of the chuck, the lower end of the adjustment block is provided with a transverse groove, the inner walls of the left and right sides of the transverse groove are rotatably connected to a bidirectional lead screw, two moving blocks are threadedly connected to the bidirectional lead screw, the two moving blocks are slidably connected to the inner wall of the transverse groove, the lower ends of the two moving blocks are fixedly connected to an L-shaped block, the adjacent sides of the two L-shaped blocks are fixedly connected to an adjustment piece, and the two adjustment pieces are located between the two chucks.

[0011] Preferably, the left side of the bidirectional lead screw extends to the outside and is fixedly connected to a knob, and the left side of the knob is provided with scale lines.

[0012] Preferably, connecting blocks are fixedly connected to both the left and right sides of the sensor body, and through holes are provided on both connecting blocks. Two vertical rods are fixedly connected to the lower end of the adjusting block, and retaining rings are fixedly connected to both vertical rods. The lower ends of both vertical rods are through holes, and threaded layers are provided on the outer walls of both vertical rods. Nuts are threadedly connected to both vertical rods.

[0013] Compared with existing technologies, the advantages of this device are:

[0014] 1. Compared with the existing technology, this device, through the setting of two clamps and the sensor body, can be adapted to the detection of insert-type contacts, thereby performing high-precision measurement of insert-type contacts, greatly improving the efficiency and accuracy of measurement.

[0015] 2. Compared with the existing technology, by setting two adjustment plates and scale lines on the knob, the distance between the two clamps can be adjusted by turning the knob, thus making the adjustment of the distance between the two clamps more accurate and convenient.

[0016] 3. Compared with the existing technology, by setting the nut and the vertical rod, after each adjustment of the distance between the clamps is completed, the nut can be removed to remove the adjusting block, thus avoiding the situation where the adjusting block obstructs and affects subsequent measurements.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1

[0024] Reference Figures 1-2 An insertable analog contact sensor includes a handle 1, which consists of a cylinder and a rectangular block. The cylinder is fixedly connected to the bottom of the rectangular block. A sensor body 2 is located at the upper end of the rectangular block. The sensor body 2 is connected to the rectangular block by multiple first bolts. Two clamps 3 are located at the upper end of the sensor body 2. Each clamp 3 has multiple first threaded holes 4. Multiple second threaded holes 5 are located at the upper end of the sensor body 2. The inner walls of each first threaded hole 4 and second threaded hole 5 are threaded together with a second bolt. The upper limit of the detection range of the sensor body 2 is 500N. An external host is provided. The data of the sensor body 2 can be stored or printed through the host, supporting subsequent analysis and traceability.

[0025] The two chucks 3 have opposite sides that are inclined, and the two chucks 3 are made of elastic steel sheets, so that the distance between the chucks 3 can be changed by the deformation of the thinner top of the chuck 3.

[0026] The functional principle of this utility model can be explained by the following operation: the sensor body 2 is fixed to the upper end of the rectangular block of the handle 1 by the first bolt, and the clamp 3 is connected to the sensor body 2 by the second bolt to form a modular assembly structure. The actual distance between the measured contacts is measured by using a vernier caliper. Then, a screwdriver or other tools are inserted between the two clamps 3. The two clamps 3 are bent by the screwdriver to adjust the distance between the two clamps 3 to ensure that effective contact pressure is generated when inserted.

[0027] Insert the clamp 3 into the gap of the insertable contact being tested, and apply a stable thrust until the sensor body 2 displays stable data. At this time, the clamp 3 undergoes elastic deformation due to pressure, and the sensor body 2 collects the pressure signal in real time and calculates and displays the stable value and the maximum value.

[0028] Example 2

[0029] Reference Figures 3-4The difference between this embodiment and embodiment 1 is that the upper end of the chuck 3 is provided with an adjustment component. The adjustment component includes an adjustment block 10 set at the upper end of the chuck 3. The lower end of the adjustment block 10 is provided with a transverse groove. The inner walls of the left and right sides of the transverse groove are rotatably connected to a bidirectional lead screw 12. Two moving blocks 13 are threadedly connected to the bidirectional lead screw 12. The two moving blocks 13 are slidably connected to the inner wall of the transverse groove. The lower ends of the two moving blocks 13 are fixedly connected to L-shaped blocks 14. The adjacent sides of the two L-shaped blocks 14 are fixedly connected to adjustment pieces 15. The two adjustment pieces 15 are located between the two chucks 3. The left side of the bidirectional lead screw 12 extends to the outside and is fixedly connected to a knob 11. The left side of the knob 11 is provided with a scale line. By setting the scale line, the knob 11 can be rotated precisely, thereby accurately adjusting the distance between the two chucks 3.

[0030] The sensor body 2 has connecting blocks 6 fixedly connected to both the left and right sides. Both connecting blocks 6 have through holes. The lower end of the adjusting block 10 is fixedly connected to two vertical rods 9. Both vertical rods 9 are fixedly connected to retaining rings 7. The lower ends of both vertical rods 9 have through holes. The outer walls of both vertical rods 9 are provided with threaded layers. Both vertical rods 9 are threaded with nuts 8, which facilitates the installation and disassembly of the adjusting block 10.

[0031] In this embodiment, after the two clamps 3 are installed, the two vertical rods 9 are inserted into the two through holes so that the two adjusting pieces 15 are located between the two clamps 3. Then, the two nuts 8 are rotated to fix the two vertical rods 9. The operator can rotate the knob 11 to drive the two adjusting pieces 15 to move in opposite directions through the two moving blocks 13, thereby adjusting the distance between the two clamps 3. This allows for more precise adjustment of the distance between the two clamps 3. After adjustment, the two nuts 8 can be removed and the adjusting blocks 10 can be taken off.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
