Description

Technical Field

[0001] This utility model relates to the field of current transformer parameter measurement technology, and in particular to a current transformer parameter measurement device for multi-channel parallel testing. Background Technology

[0002] Instrument transformer parameter measurement devices are used to detect various parameters of instrument transformers and play a crucial role in power systems. Multi-channel parallel testing refers to the device's ability to simultaneously measure the parameters of multiple instrument transformer channels, changing the traditional single-channel, one-by-one testing method. Multi-channel parallel testing significantly improves measurement efficiency, shortens testing time, and meets the demands of modern power systems for efficient and accurate instrument transformer parameter measurement. It allows multiple instrument transformers to be connected simultaneously, synchronously acquiring and analyzing parameters such as voltage and current from different channels. This avoids the channel switching losses and time delays of single-channel testing, providing a more comprehensive and real-time reflection of the instrument transformer's operating status and offering more reliable data support for performance evaluation and fault diagnosis.

[0003] In existing technologies, when performing multi-channel parallel testing of instrument transformers, they are usually installed inside the same enclosure. The installation structure design is not reasonable, and the connection methods, such as fixing screws, are usually cumbersome. Installation requires professional tools and consumes a lot of time and effort. Multiple instrument transformer measuring devices are usually installed inside cabinets or enclosures, where the internal space is relatively small, making disassembly and assembly relatively inconvenient and difficult. Moreover, the precision and sensitivity of instrument transformer equipment are relatively high, and its shock absorption protection performance is relatively poor and its buffer protection performance is inadequate when vibration and impact occur, resulting in insufficient practicality. To address these issues, we propose a multi-channel parallel testing instrument transformer parameter measuring device. Utility Model Content

This ensures stable and convenient installation and good shock absorption protection. Simultaneously, the movable sling-type slide rail 6 provides elastic support, ensuring overall elastic protection and stability. When multiple current transformer parameter testers 2 are installed inside the insulating isolation frame 3, they can be stably protected against shock absorption. The insulating isolation frame 3 can extend and retract on the sliding tracks of the movable lifting slide 6 and the shock-absorbing limiting slide 7, making it easy to store or remove the insulating isolation frame 3 from the installation box 1.

Fixed bolt plates 65 are installed on both sides of the top of the insulating isolation frame 3. The fixed bolt plates 65 are elastically mounted with spring mounting pieces 64, so that when the hanging plate 63 is suspended at the bottom of the sliding block 62, the insulating isolation frame 3 can be elastically supported by the spring mounting pieces 64, which plays an elastic buffer protection role.

[0035] Furthermore, the bottom of the spring mounting plate 64 is provided with a fixing bolt plate 65, which is bolted to the top of the insulating isolation frame 3;

[0036] Specifically, the fixed bolt plate 65 serves to fix the spring mounting plate 64, facilitating the stable and elastic lifting operation of the sliding block 62 and the lifting plate 63, providing elastic protection and stable installation load-bearing capacity.

Moreover, the rubber shock-absorbing slider 73 is made of elastic shock-absorbing rubber, which provides good shock absorption and protection while playing a supporting role.

[0039] How to use and how to work this device:

[0040] An insulating isolation frame 3 is provided inside the mounting box 1. The top of the insulating isolation frame 3 is provided with a movable lifting slide 6, which allows the insulating isolation frame 3 to be suspended and slid inside the mounting box 1. The bottom of the insulating isolation frame 3 is provided with a shock-absorbing and limiting slide 7, which allows the insulating isolation frame 3 to be elastically and shock-absorbingly supported and slid on the top of the shock-absorbing and limiting slide 7. The installation is stable and convenient, and the shock absorption and protection effect is good.

[0041] The movable sling-type slide rail 6 includes two top slide rails 61, a sliding block 62, and a sling plate 63. The top slide rails 61 are installed on the inner top wall of the mounting box 1. The sliding block 62 can slide within the top slide rails 61. Fixed bolt plates 65 are installed on both sides of the top of the insulating isolation frame 3. The fixed bolt plates 65 are elastically mounted with spring mounting pieces 64, so that when the sling plate 63 is suspended at the bottom of the sliding block 62, the spring mounting pieces 64 can elastically support the insulating isolation frame 3, providing elastic buffer protection. The shock-absorbing and limiting slide rail 7 includes a support slide rail 71 and a support slider 72, and a rubber shock-absorbing slider 73. Installed and supported at the bottom of the insulating isolation frame 3, it serves a supporting function. When the insulating isolation frame 3 slides and extends back and forth, the rubber shock-absorbing slider 73 can drive the support slider 72 to slide back and forth within the thread of the support slide 71, thus providing a supporting function. Moreover, the rubber shock-absorbing slider 73 is made of elastic shock-absorbing rubber, which provides good shock absorption protection while providing support. The rubber shock-absorbing slider 73 and the spring mounting plate 64 are elastically supported on the upper and lower sides of the insulating isolation frame 3, respectively, providing good elastic buffering and shock absorption protection. This ensures that when multiple current transformer parameter testers 2 are installed inside the insulating isolation frame 3, they can be stably protected by shock absorption.

[0042] Since the insulating isolation frame 3 can extend and retract on the movable lifting slide 6 and the shock-absorbing limiting slide 7, it is convenient to store or remove the insulating isolation frame 3 from the installation box 1, making storage and placement convenient.

[0043] The interior of the insulating isolation frame 3 is equipped with a mounting plate 4. The back of the current transformer parameter tester 2 is equipped with an auxiliary fixing part 5. The current transformer parameter tester 2 can be magnetically mounted on the mounting plate 4 by the auxiliary fixing part 5. The installation of multiple current transformer parameter testers 2 is convenient, and the insulating isolation frame 3 can isolate interference signals. Multiple current transformer parameter testers 2 can measure the current transformer parameters of multiple channels. The measurement is stable and convenient. When it is necessary to disassemble or assemble the current transformer parameter tester 2, the insulating isolation frame 3 can be pulled out of the mounting box 1, and then the auxiliary fixing part 5 can be removed from the mounting plate 4 to complete the disassembly and assembly. The operation is convenient, and the device can be pulled out of the box for quick disassembly and assembly. It also has good buffering and shock absorption protection and excellent practicality.
