Circuit for controlling the safety power cut-off system.

Abstract

The invention relates to an electrical circuit for controlling safe power interruption. Its purpose is to cut off the power supply to the source of a fire, preventing the fire from spreading, ensuring the safety of firefighters and allowing them to quickly and effectively extinguish the fire. It cuts off the power supply to prevent accidents caused by electric shock to people, stops machinery from operating to save workers, and prevents the spread of fire, electric shock, and accidents from rotating or pressing machinery, causing harm to people and property damage to businesses. The circuit includes: Emergency push buttons installed in several locations or areas where people are on duty or working, or where there is a high risk of fire, or where there is a risk of occupational accidents from rotating or pressing machinery, connected to a contactor to cause a single-phase "short circuit" of the main circuit breaker. This safely cuts off the power to people and machinery... and is linked to an automatic fire alarm system to spray water to extinguish fires and prevent their spread in buildings, floors, workshops, and areas. This is an invention of an electrical circuit for controlling safe power interruption.Applicable to all types of industrial and civil construction projects, both high and low-rise, that require fire safety, regardless of height, number of floors, or intended use.
