Description

Technical Field

[0001] This utility model relates to the field of power equipment testing technology, specifically a highly integrated dielectric loss tester. Background Technology

[0002] With the continuous development of power equipment testing technology, the requirements for the function and performance of dielectric loss testers are getting higher and higher. In order to meet the convenience and efficiency of on-site testing, multiple functional modules need to be integrated into one.

[0003] With built-in dielectric loss bridge, frequency converter, test transformer and standard capacitor, it can complete the entire process of testing from power output and voltage boost to parameter measurement without the need for additional external equipment. This integrated design can greatly reduce the size and weight of the instrument, making it easy to carry and use, while also improving the stability and accuracy of the test.

[0004] However, existing dielectric loss testers still have many problems. When working, especially during high-voltage and long-term tests, dielectric loss testers generate a lot of heat. Due to the high test voltage and the need to repeat the test multiple times to ensure data accuracy, the test components inside the instrument will generate high heat. If this heat cannot be dissipated in time, it will damage the test components inside the instrument, such as affecting the performance of the components, shortening the service life of the components, or even causing the instrument to malfunction and making it difficult to work normally.

[0005] Therefore, this invention provides a highly integrated dielectric loss tester to solve the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] This utility model provides a highly integrated dielectric loss tester, such as... Figure 1-7 As shown, the highly integrated dielectric loss tester includes a base 1, a housing 2 fixedly connected to the top of the base 1, a protective cover 3 fixedly connected to the top of the housing 2, a detection module 14 fixedly connected to the top of the base 1, and a heat dissipation component inside the base 1.

[0031] The heat dissipation assembly includes two air supply plates 13 installed inside the base 1. A motor 16 is fixedly connected to the inner wall of the left side of the housing 2. A threaded rod 18 is fixedly connected to the bottom output end of the motor 16 through a coupling. The bottom of the threaded rod 18 is rotatably connected to the top of the base 1. A drive frame 15 is threadedly connected to the outer surface of the threaded rod 18. A connecting rod 17 is hinged inside the drive frame 15.

[0032] The front and back of the housing 2 are hinged with flip plates 6. The bottom of the connecting rod 17 is hinged to the side of the flip plate 6 near the housing 2. The left side of the drive frame 15 is slidably connected to the left side of the housing 2.

[0033] Specifically, by setting up a heat dissipation component and starting the motor 16, a series of mechanical linkages drive the flip plate 6 to flip outward, thereby opening the housing 2 and providing a channel for air circulation. The flip plate 6 also provides protection for the detection module 14 inside the housing 2. By setting up and activating the air supply plate 13, the front air supply plate 13 draws in cool outside air into the housing 2 and blows it towards the detection module 14, while the rear air supply plate 13 blows air out of the housing 2, thereby removing heat, improving ventilation efficiency, reducing the impact of heat accumulation and high temperatures on the internal components of the detection module 14, and ensuring the normal passage of the handle 4.

[0034] Two filters 5 are inserted inside the housing 2. A handle 4 is fixedly connected to the top of the filter 5. A slot 7 is opened on the side of the handle 4 near the protective cover 3.

[0035] Four fixing blocks 10 are fixedly connected to the top of the box 2. The fixing block 10 located in front and the fixing block 10 located in rear are fixedly connected to a limiting rod 9 on the opposite side. A push plate 11 is slidably connected to the outer surface of the limiting rod 9.

[0036] A spring 8 is provided on the outer surface of the limiting rod 9. The side of the spring 8 near the push plate 11 contacts the side of the push plate 11 away from the fixed block 10. A locking block 12 is fixedly connected to the bottom of the push plate 11. The side of the locking block 12 away from the limiting rod 9 is inserted into the slot 7.

[0037] A connecting plate 20 is fixedly connected to the bottom of the base 1. A limiting post 19 is fixedly connected to the bottom of the connecting plate 20. A limiting cylinder 21 is slidably connected to the outer surface of the limiting post 19.

[0038] A wheel 22 is fixedly connected to the bottom of the limiting cylinder 21, and a damper 23 is fixedly connected to the top of the wheel 22. The top of the damper 23 contacts the bottom of the limiting post 19, and a spring 24 is provided on the outer surface of the damper 23.

[0039] Specifically, by setting up a filter screen 5, when the air supply plate 13 is used to dissipate heat from the detection module 14, the filter screen 5 intercepts dust and other particles carried in the air, reducing the impact of these impurities on the detection module 14 and preventing impurities from accumulating on the surface of the detection module 14 and affecting heat dissipation. Pushing the push plate 11 to one side of the spring 8, the push plate 11 drives the locking block 12 to move along the limit rod 9 towards the spring 8 until the locking block 12 is no longer stuck in the slot 7. At this time, the handle 4 can be pulled upward to remove the filter screen 5, making it easy to clean the filter screen 5.

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.
