Embodiment
As shown in Figure 1, a kind of device for the tonifying Qi in service of air insulation class switchgear, by gas piping, to be connected with adsorbent equipment 2 by small-sized dry air compressor 1, one end of this gas piping is connected with the dry air gas cylinder 3 that is preinstalled with qualified dry air by metal triple valve A 4, metal triple valve A 4 is connected with pressure-reducing valve 6 with gas pressure Table A 5 successively by another pipeline, and pressure-reducing valve 6 is connected with non-return valve 7, safety valve 8, gas gauge B 9, metal triple valve B 10 by pipeline successively; Metal triple valve B 10 connects atmospheric pipe 11 by pipeline, and metal triple valve B 10 is connected with the air insulated switch equipment 12 for the treatment of tonifying Qi by another pipeline.
Feature of the present invention is, when air insulated switch equipment is carried out to tonifying Qi, in two ways optional.
Mode one: after dry compressed air being removed to the impurity such as its medium sulphide content by adsorbent equipment 2 by small-sized dry air compressor 1, equipment is inflated, step is: use metal triple valve A 4 that adsorbent equipment 2 is communicated with pressure-reducing valve 6; Use metal triple valve B 10 that gas passage is communicated with atmospheric pipe 11, then open 1 pair of tonifying Qi pipeline of small-sized dry air compressor and rinse, remove wherein residual gas; Close small-sized dry air compressor 1; Use metal triple valve B 10 that gas passage is communicated with needing the air insulated switch equipment 12 of tonifying Qi; Open 1 pair of air insulated switch equipment of small-sized dry air compressor 12 and carry out tonifying Qi, in operation, note observing gas pressure Table A 5 and gas gauge B 9, avoid the not enough and excessive tonifying Qi of tonifying Qi.
Mode two, directly select the qualified dry air in dry air gas cylinder 3 to inflate equipment, step is: use metal triple valve A 4 that adsorbent equipment 2 is communicated with pressure-reducing valve 6; Use metal triple valve B 10 that gas passage is communicated with atmospheric pipe 11, then open 1 pair of tonifying Qi pipeline of small-sized dry air compressor and rinse, remove wherein residual gas; Close small-sized dry air compressor 1; Use metal triple valve A 4 that dry air gas cylinder 3 is communicated with pressure-reducing valve 6, open dry air gas cylinder 3 valves, with qualified dry air, again air supply passage is rinsed; Closing dry air gas cylinder 3 valves stops rinsing; Use metal triple valve B 10 that gas passage is communicated with needing the air insulated switch equipment 12 of tonifying Qi; Open dry air gas cylinder 3 valves air insulated switch equipment 12 is carried out to tonifying Qi, in operation, note observing gas pressure Table A 5 and gas gauge B 9, avoid the not enough and excessive tonifying Qi of tonifying Qi.
