Kapcsolóberendezésekre, often translated as switchgear, refers to a comprehensive assembly of electrical components used to control, protect, and isolate electrical equipment in power systems. These systems are essential for the safe and efficient operation of electricity distribution and transmission networks, as well as for industrial and commercial power installations.

The primary function of switchgear is to interrupt or close electrical circuits. This is crucial for a variety of operations, including connecting and disconnecting power sources, isolating faulty sections of a network, and rerouting power flow. Components typically found within switchgear include circuit breakers, switches, fuses, disconnectors, relays, and current and voltage transformers.

Circuit breakers are a key element, designed to automatically interrupt fault currents, thereby protecting the system from damage caused by short circuits or overloads. Relays monitor the electrical parameters and initiate the tripping of circuit breakers when abnormal conditions are detected. Disconnectors are used to isolate equipment for maintenance or repair, ensuring that no voltage is present.

Switchgear is categorized based on voltage levels, such as low voltage, medium voltage, and high voltage switchgear, each designed to handle specific electrical stresses and applications. The design and configuration of switchgear are critical for system reliability, safety, and operational flexibility. They are housed in various enclosures, from open-air substations to enclosed cabinets and cubicles.
