Lekapcsolás

Lekapcsolás is disconnection or deactivation and refers to the act of separating a device, circuit, or system from its power source or network. It is used to stop energy flow, to isolate a part of a installation for safety, maintenance, or fault management, and can be achieved manually or automatically.

In electrical engineering and power systems, lekapcsolás is the intentional opening of a switch or tripping of a protection device to disconnect a section of a circuit. This isolation protects personnel, prevents fault propagation, and allows work to be performed safely. Manual lekapcsolás can be done by operators, while automatic lekapcsolás occurs via protective relays, circuit breakers, or fuses in response to faults or abnormal conditions. Proper procedures and clear tagging are required to avoid accidental re-energization.

In consumer electronics and energy management, lekapcsolás commonly means turning off a device or unplugging it from the power source. It reduces energy consumption, eliminates standby power draw, and protects equipment during maintenance. In information technology and telecommunications, lekapcsolás may refer to disconnecting from a network or service, ending a session, or terminating a connection for reasons such as maintenance, security, or service withdrawal.

Safety and procedure aspects often accompany lekapcsolás. Lockout and tagout practices are used to ensure that equipment cannot be re-energized during service. Residual or stored energy may require verification before work begins. Overall, lekapcsolás is a fundamental concept across engineering, operations, and service contexts to manage energy, protect people, and maintain systems.
