In the rapidly evolving landscape of modern electrical infrastructure, the demand for efficient, reliable, and space-saving power solutions has never been greater. The compact substation, often referred to as a compact power distribution unit, has emerged
In 10kV and above medium-voltage power distribution systems, metal-clad withdrawable switchgear plays a crucial role in power distribution, control, and protection.
In modern power systems, the safety, reliability, and intelligence of equipment have become core standards for measuring overall operational quality.
Due to the dense spatial layout, compact substations are prone to electromagnetic coupling interference when high-pressure and low-pressure chambers are arranged adjacently, which can affect the stability and safety of equipment operation.
As a key device in a 10kV distribution system, the ring main unit effectively improves power supply continuity and reduces outage risk through ring network power supply and intelligent protection technologies.
Electrical interlocks detect the position status of the drawer through auxiliary contacts or sensors and feed the signal back to the control system.
