Intelligent fire fighting electrical control device

Abstract

The invention discloses an intelligent fire fighting electrical control gear which comprises an air circuit breaker, a control gate circuit, a main control unit and an electric leakage prechecking protective circuit, wherein the electric leakage prechecking protective circuit is connected with the control gate circuit and the main control unit; the control gate circuit is connected with an opening / closing locked coil of the air circuit breaker; and the air circuit breaker is connected in a main three-phase power supply loop in series. The intelligent fire fighting electrical control device also comprises a temperature prechecking protective circuit, a default phase sampling circuit, a voltage sampling detection and over-voltage low-voltage protective circuit, an electric current sampling detection and overcurrent open-phase protective circuit, a short-circuiting protective circuit and a short-circuiting prechecking circuit. The intelligent fire fighting electrical control device has the characteristics of multifunction and intellectualization and is beneficial to ensuring the safe operation of electric equipment.

Description

technical field [0001] The invention relates to a fire intelligent electric control device. Background technique [0002] Electricity is closely related to people's life and is widely used in life. Electricity safety affects all walks of life and social stability, and life and industry electricity consumption is more important. However, due to unreasonable use and operation or the aging of the line itself, the abnormal temperature of the line causes leakage, short circuit, etc., making electricity an invisible "killer" around people. Fires and casualties caused by electric accidents are often huge. For many years, relevant departments and enterprises have focused on engineering electric fire-fighting equipment, aiming to take timely corresponding measures when accidents occur to control the spread of electric accidents. At present, relevant security equipment only focuses on safety precautions when or after an accident occurs, but hidden dangers often exist before the powe...

AI Technical Summary

Problems solved by technology

At present, relevant security equipment only focuses on safety precautions when or after an accident occurs, but hidden dangers often exist before the power supply line is connected.

Problems such as line temperature abnormality, short circuit, and leakage that exist before the power line or power equipment is connected in traditional power security equipment cannot be predicted and solved. Therefore, there are still major safety hazards in the existing power security equipment
