Description
Technical Field
The invention relates to a fixed gas detector, in particular to a multifunctional fixed gas detector.
Background
At present, in an explosive gas detection environment, the types of gas detection equipment are more, and the application of a fixed gas detector is increasingly wide. The gas detector is normally powered by a DC24V DC power source, and the detector is powered by a UPS in a control room through an explosion-proof hose, but some field environment equipment is single, has no UPS, and only has an AC22V AC power source, and when the detector is powered, a control box with higher cost needs to be installed firstly to convert AC220V into DC 24V.
disclosure of Invention
In order to overcome the defect of higher cost of a control box, the invention provides a multifunctional fixed gas detector which is characterized in that an explosion-proof junction box is arranged at an electrical interface of the detector, a power supply module is arranged in the detector, and an AC220V dual-energy DC24V power supply can be arranged according to the power supply requirement.
The purpose of the invention is realized as follows:
A fixed gas detector comprises an explosion-proof junction box, a detector and an audible and visual alarm; the method is characterized in that: the detector is connected with the explosion-proof junction box through the junction box reducing diameter, and the detector is connected with the audible and visual alarm through the audible and visual reducing diameter; the bottom of the detector is connected with a sensor; and the explosion-proof junction box is provided with a cable lead-in device.
The technical scheme adopted by the invention is as follows: the fixed gas detector comprises an explosion-proof junction box, a gas detector and an audible and visual alarm. The explosion-proof junction box is arranged on the left side of the detector, the audible and visual alarm is arranged on the right side of the detector, the two end devices are connected in an explosion-proof reducing mode, 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 an internal terminal wire of the explosion-proof junction box through the lead-in device, and when the cable is connected, an AC220V power supply can be connected and a DC24V power supply can be connected.
The invention has the beneficial effects that: the explosion-proof junction box is arranged at the electrical interface of the detector, the power supply module is arranged in the explosion-proof junction box, and an AC220V dual-power DC24V power supply can be installed according to the power supply requirement.
