Fig. 2 is this device operation principle schematic diagram;
Fig. 3 is the example structure schematic diagram;
Fig. 4 is the operation principle schematic diagram of embodiment.
The specific embodiment
This device both can be manual, also can be automatic, below in conjunction with accompanying drawing, be described further with the example that operates to automatically of this device.
In this example, this device is that the online dehumidifying that applies to the sulfur hexafluoride gas in the SF 6 arc-extinguishing chamber of circuit breaker 10 removes poison, and with reference to figure 2,3, the main line inlet end of this device is connected arc-chutes with the outlet side.
With reference to figure 1, the online dehumidifying of a kind of gas removes malicious device, comprises gas comprehensive detection device 2, gas-filtering device 5, circulating pump 7 and main line; Gas comprehensive detection device 2, gas-filtering device 5 and circulating pump 7 are located on the main line; With described gas-filtering device 5 circulation lines that are provided with in parallel; The open/close state that all is provided with air valve 8,9, two air valves on gas-filtering device 5 and circulation line is different.Described two air valves can a shared two-position three way valve.
With reference to figure 3, in this example, described two-position three way valve has two, is provided in a side of the discharge type two-position three way valve 3 of circulation line and gas-filtering device 5 inlet end junctions respectively and is located at circulation line and the reversing two-position three way valve 4 of gas-filtering device 5 exhaust end junctions.Described two-position three way valve adopts controlled three-way valve.
This device also comprises control circuit, and the input of control circuit connects the control output end of gas comprehensive detection device, and the output of control circuit connects the control end of described two-position three way valve by drive circuit.
The inlet end of the outlet side of described discharge type two-position three way valve 3, reversing two-position three way valve 4 is provided with closed type magnetic valve 6; Be in communication with the outside end on the gas-filtering device and be provided with closed type magnetic valve 6 '; The output of control circuit connects closed type magnetic valve 6 and 6 ' by drive circuit.
