Description

Technical Field

[0001] The utility model belongs to the technical field of transformer limit devices, and in particular relates to an auxiliary limit device for installing a transformer in a power transmission and transformation project. Background Art

[0002] In the key links of power transmission and distribution, transformers play a core role, and the accuracy and stability of their installation are crucial to the reliable operation of the entire power system. However, during the installation of transformers, due to the lack of efficient auxiliary limiting devices, low installation efficiency, insufficient installation accuracy, and possible damage to the equipment during installation are often encountered. The above not only increases the installation cost, but also may cause instability in the power system and even lead to safety accidents. In existing technical practices, the installation of transformers mainly relies on manual operation and simple fixing devices, which often fail to meet the high standards of modern power systems for installation accuracy and efficiency. Due to the lack of precise limiting and positioning mechanisms, transformers are prone to displacement or tilt during installation, making it difficult to ensure installation accuracy. In the absence of effective limiting measures, transformers are prone to impact or extrusion during installation, increasing the risk of equipment damage. In addition, existing limiting devices are difficult to adapt to transformers of different models and sizes, limiting their scope of application. Furthermore, due to the lack of stable support and limiting structures, the transformer may be displaced by external forces after installation, thereby affecting the stability of the power system.

[0003] In the prior art, there is a transformer installation auxiliary limit device with announcement number CN214476817U. The device drives the driven gear to rotate through the active gear, and then rotates the threaded rod in the threaded groove to adjust the position of the embedded rod and realize the movement of the limit plate, thereby assisting the installation of the transformer and limiting its position, ensuring stability and accuracy during the installation process; however, the adjustment mechanism of the active gear and the driven gear increases the complexity and potential failure points of the device, which is not conducive to long-term and frequent use.
