Abstract

The invention discloses a fixed gas detector. The fixed gas detector comprises an explosion-proof junction box, a detector and an audible and visual alarm, the detector is characterized in that the detector is connected with the explosion-proof junction box in a reducing manner through the junction box, and is connected with the audible and visual alarm in an audible and visual reducing manner; the bottom of the detector is connected with a sensor; and a cable leading-in device is arranged on the explosion-proof junction box. According to the technical scheme, the fixed gas detector comprisesthe explosion-proof junction box, the gas detector body and the audible and visual alarm. The explosion-proof junction box is arranged at the left side of the detector, the audible and visual alarm isarranged at the right side of the detector, the connection mode between equipment at two ends adopts explosion-proof reducing, and an explosion-proof sensor structure is designed below the detector.A lead-in device is arranged on the left side of the explosion-proof junction box, a power supply cable is connected with a terminal in the explosion-proof junction box through the lead-in device in awiring mode, and when the cable is connected, AC220V power can be connected, and DC24V power can be connected.
