Description

Technical Field

[0001] This utility model relates to the field of harmonic detector technology, specifically a high-voltage transmission line harmonic detector that is easy to use. Background Technology

[0002] The user-friendly high-voltage transmission line harmonic detector is an intelligent testing device specifically designed for power systems. It efficiently and accurately measures harmonic parameters of high-voltage transmission lines, significantly reducing the operational threshold and improving on-site testing efficiency. The detector features an integrated, portable design, is compact and lightweight, and is equipped with a non-slip handle and shock-resistant casing, making it suitable for high-altitude operations or carrying in complex environments. No complex wiring is required; signals can be quickly acquired using a high-voltage clamp sensor or a wireless non-contact probe, avoiding the cumbersome process of power-off operation required by traditional testing methods and ensuring testing safety. It has a built-in high-precision harmonic analysis chip that can measure voltage / current harmonic distortion rate (THD), amplitude and phase angle of each harmonic (supporting harmonics 2-63) in real time, and automatically identify the type of harmonic source (such as rectifier loads, electric arc furnaces, etc.). Test results are directly displayed on a color touchscreen and support data storage, export (USB / Bluetooth), and cloud synchronization for convenient subsequent analysis. The instrument features a built-in intelligent diagnostic algorithm that automatically determines whether harmonics exceed standards (compliant with GB / T14549-93) and provides mitigation suggestions. Its low-power design, coupled with a large-capacity battery, allows for over 8 hours of continuous operation on a single charge, meeting all-weather field requirements. Its "one-button start + automatic calibration" function further simplifies operation, allowing for quick mastery without professional training, significantly improving the convenience and reliability of harmonic detection for transmission lines.

[0003] However, the plug and connector of the easy-to-use high-voltage transmission line harmonic detector are unstable during use and are prone to loosening, resulting in inaccurate data. Utility Model Content

[0004] The purpose of this utility model is to provide an easy-to-use high-voltage transmission line harmonic detector, which solves the problem that the plug and connector of the easy-to-use high-voltage transmission line harmonic detector are unstable and prone to loosening during use, resulting in inaccurate data.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a user-friendly high-voltage transmission line harmonic detector, comprising a harmonic detector body, a mounting base contacting the outer side of the harmonic detector body, an elastic pad fixedly connected to the outer side of the mounting base, the elastic pad being slidably sleeved with the harmonic detector body, a slider slidably connected inside the mounting base, a locking block fixedly connected to the side of the slider near the harmonic detector body, a locking groove opened inside the harmonic detector body, a fixing rod fixedly connected inside the mounting base, the fixing rod being slidably connected to the slider, a spring provided on the outer side of the fixing rod, and a fixing mechanism provided on the harmonic detector body.

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.

[0017] Please see Figure 1-4A user-friendly high-voltage transmission line harmonic detector includes a harmonic detector body 1. A mounting base 2 contacts the outer side of the harmonic detector body 1. An elastic pad 21 is fixedly connected to the outer side of the mounting base 2, and the elastic pad 21 is slidably sleeved with the harmonic detector body 1. A slider 22 is slidably connected inside the mounting base 2. A locking block 23 is fixedly connected to the side of the slider 22 closest to the harmonic detector body 1. A locking groove 24 is provided inside the harmonic detector body 1. The locking block 23 contacts the mounting base 2 and is slidably connected to the locking groove 24. The design of the locking block 23 can limit the movement of the mounting base 2.

[0018] Please see Figure 2-4 The mounting base 2 has a fixed rod 25 inside, which is slidably connected to the slider 22. A spring 26 is provided on the outside of the fixed rod 25. One end of the spring 26 contacts the slider 22, and the other end of the spring 26 contacts the mounting base 2. The spring 26 can drive the locking block 23 to engage with the harmonic detector body 1. A push block 27 is fixedly connected to the side of the slider 22 away from the harmonic detector body 1. The push block 27 contacts the mounting base 2. The push block 27 can be easily moved. A fixing mechanism 3 is provided on the harmonic detector body 1.

[0019] Please see Figure 2-4 The fixing mechanism 3 includes a plug 31. The plug 31 is provided at the upper end of the harmonic detector body 1. A connector 32 is inserted into the outside of the plug 31. A fixing block 33 is fixedly connected to the upper end of the harmonic detector body 1. The fixing block 33 contacts the connector 32. A limit sleeve 34 is rotatably connected to the outside of the fixing block 33. The limit sleeve 34 contacts the harmonic detector body 1. The limit sleeve 34 and the connector 32 are connected by threads. A protrusion 35 is fixedly connected inside the limit sleeve 34. The protrusion 35 is slidably connected to the limit sleeve 34. The protrusion 35 can limit the limit sleeve 34 through its design. A positioning frame 36 is fixedly connected to the outside of the connector 32. The positioning frame 36 is slidably connected to the harmonic detector body 1. The positioning frame 36 contacts the limit sleeve 34 through its design. The positioning frame 36 can position the connector 32 through its design. The fixing mechanism 3 can keep the connector 32 and the plug 31 connected stably.

[0020] The specific implementation process of this utility model is as follows: In use, by moving the two push blocks 27 toward each other, the push blocks 27 drive the slider 22 to move on the fixed rod 25, so that the slider 22 squeezes the spring 26. Then, by connecting the elastic pad 21 with the harmonic detector body 1, the locking block 23 on the mounting base 2 slides into the locking groove 24 on the harmonic detector body 1. Then, by releasing the push blocks 27, the slider 22 can be moved by the elastic force of the spring 26, so that the slider 22 drives the locking block 23 to engage with the harmonic detector body 1, so that the elastic pad 21 can remain stable after installation. By inserting the connector 32 into the plug 31, the connector 32 drives the positioning frame 36 to slide into the main body 1 of the harmonic detector. Then, the limiting sleeve 34 is rotated, causing the limiting sleeve 34 and the connector 32 to move in a threaded motion. This allows the limiting sleeve 34 to limit the connector 32, thus keeping the connection between the connector 32 and the plug 31 stable and preventing the connector 32 and the plug 31 from becoming loose.
