Description

Technical Field

[0001] The utility model relates to the technical field of cable fixing, in particular to a cable fixing device for a transformer substation. Background Art

[0002] A photovoltaic power station is a system that harnesses solar energy and utilizes specialized materials such as crystalline silicon panels, inverters, and other electronic components to generate electricity. It is connected to the power grid and transmits electricity to the grid. Photovoltaic power stations are among the green power development projects receiving the most significant national encouragement. A cable is a device for transmitting electrical energy or signals, typically consisting of several or several groups of conductors. Cables include power cables, control cables, compensation cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, and aluminum alloy cables. They are composed of single or multiple strands of conductors and an insulating layer, and are used to connect circuits and electrical appliances.

[0003] Patent document CN 217036339U discloses a cable fixing device for photovoltaic substations. This device features a first fixing seat movably connected to a second fixing seat at the top. The first and second fixing seats are closed and connected by a second movable bolt, allowing the first and second fixing seats to secure the cable. Rotating the first movable bolt at the top of the second fixing seat allows the first movable bolt to push a limit clamp below via a rotating shaft, causing the limit clamp to adhere to the surface of the cable, thereby securing cables of varying sizes. However, when a cable needs to be installed or disassembled, turning the first movable bolt causes the three limit clamps to separate from the cable, separating the limit clamps from the other already secured cables. Furthermore, tightening the two bolts up and down can cause the two bolts to loosen over time, making it difficult to secure the cable with the limit clamps. Furthermore, cleaning the cable is difficult, and dust accumulates in the through-holes. Utility Model Content
