Portable SF6 device gas leakage and abnormality voice recognition warning device

Abstract

The invention relates to a portable SF6 device gas leakage and abnormality voice recognition warning device and belongs to the technical field of power industries. A power switch is arranged on an outer shell, an acquisition sensor is arranged at the top end of the outer shell, a circuit board is arranged at the upper portion inside the outer shell, and a battery clamp is arranged at the lower portion of the circuit board; a voice chip, voice output, a power supply, a first digital to analog conversion device, a central processing unit and a second digital to analog conversion device are arranged on the circuit board; the acquisition sensor, the voice chip, the power supply, the first digital to analog conversion device and the second digital to analog conversion device are all connected with the central processing unit, and the voice output is connected with the voice chip and a buzzer. The portable SF6 device gas leakage and abnormality voice recognition warning device plays a role in compensating operation dead corners of the device and a role in warning, and is simple in structure and flexible and convenient to use. Scale values under different working environment conditions can be set, an alarm is given to staff in a working site so that the staff can make an accurate judgment and keep a safe enough distance from the working environment, and personal safety and safe operations of the device are ensured.

Description

Technical field [0001] The invention relates to a portable SF6 equipment gas leakage and abnormal voice recognition alarm device, which belongs to the technical field of the electric power industry. Aiming at the conditions of existing equipment and technology, it provides a voice recognition and prompt alarm device for preventing SF6 gas leakage and scorched gas generated by abnormal temperature of enclosed equipment in substation operation equipment indoors or in the indoor environment of enclosed combined electrical appliances. Background technique [0002] At present, with the improvement of the automation and modernization of power equipment, combined electrical appliances with SF6 as insulating gas and various enclosed switch cabinets with built-in vacuum insulation equipment have long replaced open-type oil-less mechanical equipment, but due to the use of combined electrical appliances And a variety of enclosed switch cabinets with built-in vacuum insulation equipment. The...
