Abstract

The invention discloses a safety warning indicator for power construction personnel. The safety warning indicator is characterized by comprising a shell (1), a state grid corporation of China (SGCC) icon (1), a receiving antenna (3) and a sling hole (2), wherein a main circuit board (4) and a battery (5) are arranged in the shell (1); the main circuit board (4) comprises an integrated circuit HEF4011BP and resistors R1-R8, an aluminum electrolytic capacitor C1, a leaded multilayer ceramic capacitor C2, a diode IN4148, a switch S1 (SW-SPDT), a switch S2 (SW-PB), a triode Q1 (9013) and a buzzer LS1. The safety warning indicator for power construction personnel is simple and practical in structure, can remind the construction operation personnel of paying attention to safety, can prevent power construction personnel from entering electrified areas and getting close to live equipment during work by mistake, can ensure personal safety of power construction personnel and device safety, and can further prevent human electric shock accidents.

Description

Technical field: [0001] The invention relates to a safety warning device for electric power construction personnel, which is widely used in electric power system construction sites and belongs to the technical field of electric power system construction maintenance work sites.
