Description

Technical Field

[0001] This utility model relates to the field of high voltage switchgear technology, and in particular to a floor-mounted high voltage disconnect switchgear. Background Technology

[0002] High-voltage switchgear, also known as high-voltage distribution cabinet or high-voltage electrical control cabinet, is a type of high-voltage power distribution equipment used in power systems. Its main functions include switching, controlling, and protecting power during generation, transmission, conversion, and consumption. High-voltage switchgear is widely used in various industrial and civil power systems, especially in applications requiring high reliability and safety control, such as hospitals, data centers, and high-rise buildings. Therefore, high-voltage switchgear is an indispensable and crucial component of power systems.

[0003] Existing high-voltage switchgear uses mounting brackets to move insulation plates within the cabinet, thereby improving the ease of adjusting the spacing between the insulation plates and enhancing controllability during use. The mounting brackets are then fixed with locking bolts to ensure stability and improve the safety performance of the insulation plates. However, this method involves numerous steps and is not sufficiently stable; the bolt-locking method is prone to slippage, affecting the fixing effect. A search revealed that the technical solution provided by utility model application number CN202321556222.2 also suffers from the aforementioned problems. Utility Model Content

When it is necessary to change the position of the partition, by rotating the knob, the rotation of the knob drives the threaded rod to rotate. Restricted by the U-shaped groove, the rotation of the threaded rod drives the connecting plate to slide back and forth. The sliding of the connecting plate drives the guide slider to slide inside the guide groove. Restricted by the inclined surface of the guide slider, the back and forth sliding of the guide slider drives the wedge block to slide left and right. The sliding of the wedge block drives the connecting rod to slide. The sliding of the connecting rod drives the locking block to slide.
