The invention relates to an externally-connected type ozone synchronous detection device for switch cabinets and application of the externally-connected type ozone synchronous detection device for the switch cabinets. An exhaust pipe is arranged in each switch cabinet in a switch cabinet set and connected with an externally-connected ozone detection device. The gas input end of a multi-channel selective type electromagnetic valve of the ozone detection device is connected with the exhaust pipes, the gas output end of the electromagnetic valve is connected with the gas input end of a flow control valve, an ozone sensor is arranged on a gas channel at the gas output end of the flow control valve and then connected with an exhaust sampling pump, a master control panel is connected with a circuit of the multi-channel selective type electromagnetic valve and controls a gas channel of the multi-channel selective type electromagnetic valve to be opened and closed, and the master control panel further controls the flow and the pressure of gas entering the flow control valve from the multi-channel selective type electromagnetic valve through a pressure switch connected with a circuit of the master control panel, a data display and input module and a data storage and analysis module are respectively connected with the master control panel, and display, input adjustment, storage and analysis are carried out on parameters obtained by the master control panel.
Description
technical field [0001] The invention relates to a detection device, in particular to a detection device arranged in an electric switch cabinet for real-time detection of ozone concentration. Background technique [0002] At present, with the increasing development of smart grid technology, smart power plants, substations and power distribution stations, one of its infrastructures, are also being updated. In such power facilities, there are often electrical switch cabinets loaded with a large number of power equipment, and Electrical switchgear is a kind of power distribution equipment that plays a role in control and protection in the power system. It is basically composed of a cabinet body and electrical components. The frame of a general low-voltage switchgear is made of aluminum alloy profiles, and the door panels are coated with aluminum and zinc. Steel plate, environmental protection and corrosion resistance. Electrical components include small circuit breakers, variou...
