Lülitusseadmed, commonly referred to as switchgear, are a combination of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate electrical equipment. They are used in power systems to de-energize equipment for safe maintenance and to quickly isolate faults, preventing damage to the electrical grid and ensuring continuity of service. Switchgear is crucial for the reliable operation of any electrical power system, from small industrial plants to large transmission networks.

The primary function of switchgear is to safely interrupt or connect electrical circuits. This can be done manually or automatically. In its simplest form, a switchgear assembly includes a means of disconnecting the circuit from the power source, a means of interrupting current flow (like a circuit breaker), and a means of protection (like fuses or relays). Modern switchgear often incorporates advanced control and monitoring systems, allowing for remote operation and diagnostics.

Switchgear can be broadly categorized into indoor and outdoor types. Indoor switchgear is typically housed in electrical substations or control rooms and is often of the metal-clad or metal-enclosed variety. Outdoor switchgear is designed to withstand environmental conditions and is commonly found in substations on steel structures or in cabinets. The voltage level of the system dictates the type and complexity of the switchgear required, with high-voltage switchgear being significantly more robust and sophisticated than low-voltage counterparts. The proper selection, installation, and maintenance of lülitusseadmed are paramount for the safety and efficiency of electrical power distribution.
