AI Technical Summary
The existing ultra-high voltage substation cables lack protection and fixing mechanisms at the interface, resulting in unstable connection between the cables and the electronic components inside the distribution cabinet. They are prone to falling off due to external force and have poor stability.
A cable connection protection mechanism is designed, including a drive unit, a first cable clamping unit, and a second cable clamping unit. The motor drives the rotating shaft to drive the rotating rod, so that the clamping plates move in opposite directions to clamp the cable. The rainproof mechanism formed by the extension plate and the limiting block prevents rainwater from splashing.
It improves the connection stability between cables and electronic components, prevents cables from falling off, and enhances the safety of the device in rainy weather, preventing short circuits caused by rain splashes.
