Description
Technical field
This utility model relates to a kind of power-off protection apparatus, a kind of power-off protection apparatus using catalyst.
Background technology
Gas chromatograph-mass spectrometer is the device that GC with MS is integrated, has a turbine pump at MS end, and turbine pump has down high rotating speed, and structure itself is the most accurate, mutual close-packed arrays between blade.After power failure, turbine pump rotating speed from normal operating conditions drops to 0 needs long time, if restored electricity during this, turbine pump is again started up rotating, and is easily smashed by the blade of turbine pump, causes turbine pump to scrap；And change new turbine pump and need hundreds thousand of units, also can affect that laboratory normally works carries out.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of power-off protection apparatus using catalyst, it is ensured that GCMS device turbine pump after a loss of power can reduction of speed smoothly, will not be caused damage by because the secondary after power-off is sent a telegram here.
The technical scheme provided according to this utility model, the power-off protection apparatus of described employing catalyst, including the Three-hole socket of connection gas chromatograph-mass spectrometer, it is characterized in that: catalyst is installed before described Three-hole socket；Described catalyst has coil, the first switch, second switch and the 3rd switch, coil one end of catalyst connects zero line and one end of the first switch respectively, one end of second switch connects live wire and one end of the first button respectively, one end of 3rd switch connects the other end and one end of the second button of the first button respectively, the other end of coil connects the zero line jack of Three-hole socket, the other end of the first switch, the other end of second switch, the other end of the 3rd switch and the other end of the second button, the firewire jack of the other end Three-hole socket of second switch respectively.
Further, the ground wire jack ground connection of described Three-hole socket.
Further, described first button is normally closed button.
Further, described second button is normally opened button.
The power-off protection apparatus of employing catalyst described in the utility model, before being installed on the Three-hole socket connecting GCMS, it is ensured that GCMS turbine pump after a loss of power can reduction of speed smoothly, will not be subject to send a telegram here because of the secondary after power-off, and cause unnecessary loss.
Accompanying drawing explanation
Fig. 1 is the structural representation of the power-off protection apparatus of employing catalyst described in the utility model.
Detailed description of the invention
Below in conjunction with concrete accompanying drawing, the utility model is described in further detail.
As shown in Figure 1: the power-off protection apparatus of described employing catalyst includes Three-hole socket 1, catalyst 2, coil 2-1, the first switch 2-2, second switch 2-3, the 3rd switch 2-4, normally closed button 3, normally opened button 4 etc..
As it is shown in figure 1, the power-off protection apparatus of employing catalyst described in the utility model, including the Three-hole socket 1 of connection gas chromatograph-mass spectrometer, catalyst 2 is installed before Three-hole socket 1；Described catalyst 2 has coil 2-1, first switch 2-2, second switch 2-3 and the 3rd switch 2-4, coil 2-1 one end of catalyst 2 connects zero line and one end of the first switch 2-2 respectively, one end of second switch 2-3 connects live wire and one end of normally closed button 3 respectively, one end of 3rd switch 2-4 connects the other end and one end of normally opened button 4 of normally closed button 3 respectively, the other end of coil 2-1 connects the zero line jack of Three-hole socket 1 respectively, the other end of the first switch 2-2, the other end of second switch 2-3, the other end of the 3rd switch 2-4 and the other end of normally opened button 4, the firewire jack of the other end Three-hole socket 1 of second switch 2-3, the ground wire jack ground connection of Three-hole socket 1.
Work process of the present utility model: when normally opened button 4 is pressed, electric current, through the coil 2-1 → zero line of live wire → normally closed button 3 → normally opened button 4 → catalyst 2, forms loop, now catalyst 2 is energized, coil 2-1 produces magnetic force, three groups of switches in adhesive catalyst 2, makes Three-hole socket 1 be energized；Unclamping normally opened button 4 again, electric current, through the coil 2-1 → zero line of live wire → normally closed button 3 → catalyst 2, still forms loop, now catalyst electricity consumption, and Three-hole socket is energized.When now power-off (or normally closed button is pressed), catalyst power-off, deactivation coil demagnetization force, it is impossible to adhesive contactless contactor, Three-hole socket power-off.
Before this utility model is installed on the Three-hole socket connecting GCMS, it is ensured that GCMS turbine pump after a loss of power can reduction of speed smoothly, will not be subject to send a telegram here because of the secondary after power-off, and cause unnecessary loss.
