Description
Technical field
The invention belongs to application in substations equipment technical field, particularly relate to a kind of oil chromatography on-Line Monitor Device being convenient to monitor nebulizer gas pressure.
Background technology
The carrier gas that chromatography online monitoring system for transformer oil uses mostly is high pure nitrogen, and the general High Purity Nitrogen gas cylinder that uses is as carrier gas source.In steel cylinder, nitrogen amount is limited, high pure nitrogen will be there is after using a period of time to be finished or the under-voltage situation cannot carrying out detecting, although there is nebulizer gas pressure to point out, but need the long period Deng the under-voltage producer's replacing gas cylinder that contacts again of nebulizer gas pressure instruction, the continuity of on-line monitoring system monitoring function just cannot be guaranteed.Can only uncapping machine chamber door for observing nebulizer gas pressure, at the scene that equipment is numerous, many single steppings are with regard to bull point responsibility.Therefore, the stability and reliability that find the not enough guarantee plant running of nebulizer gas pressure is timely only had.
Summary of the invention
For above-mentioned prior art Problems existing, the invention provides a kind of oil chromatography on-Line Monitor Device being convenient to monitor nebulizer gas pressure, its object provides a kind of cabinet with the transformer oil gas on-Line Monitor Device being convenient to monitor nebulizer gas pressure of visual window, two monitoring modular.Its objective is that case lid door of can starting shooting at the scene just can check carrier gas bottle pressure intuitively, not only can check that carrier gas bottle pressure can also check the gaseous tension after decompression on backstage.
The technical solution adopted for the present invention to solve the technical problems is:
Be convenient to the oil chromatography on-Line Monitor Device monitoring nebulizer gas pressure, comprise gas filling bottle, reduction valve and pressure transducer; Be provided with view window on the sidewall of casing, the gas filling bottle that casing is built-in is connected with nebulizer gas pressure table and carrier gas delivery gauge in bottle, in bottle, nebulizer gas pressure table is by the sense line Bonding pressure sensor on reduction valve, and pressure transducer and carrier gas analysis module are all arranged in main frame; Reduction valve and pressure transducer are connected to main frame by pressure sensing line; Carrier gas analysis module is provided with in main frame, can by data upload to backstage.
Described view window is that the material that glass or transparent plastic class transparency are strong is made.
The utility model is a kind of oil chromatography on-Line Monitor Device being convenient to monitor nebulizer gas pressure; adopt this structure; can without the machine box door of device for opening when working at the scene; only need to check carrier gas bottle pressure by transparency window; avoid site work personnel and open the device exception of maloperation initiation or the generations of device power failure phenomenon such as cabinet mistake crash device power supply, the personal safety of operating personnel is necessarily ensured.On backstage, staff not only can check the gaseous tension after reduction valve, can also check carrier gas bottle pressure, is convenient to prepare new carrier gas bottle in advance, avoids using up due to carrier gas and the generation of the device cisco unity malfunction phenomenon caused.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: device cabinet 1, view window 2, nebulizer gas pressure table 3 in bottle, carrier gas delivery gauge 4, sense line 5, reduction valve 6, pressure transducer 7, carrier gas analysis module 8, main frame 9.
Embodiment
As shown in Figure 1, the utility model is a kind of oil chromatography on-Line Monitor Device being convenient to monitor nebulizer gas pressure, the sidewall of casing 1 is provided with the view window 2 of observable nebulizer gas pressure, nebulizer gas pressure table 3 and carrier gas delivery gauge 4 in the bottle that the gas filling bottle that casing 1 is built-in connects can be seen by view window 2, in bottle, nebulizer gas pressure table 4 is by the sense line 5 Bonding pressure sensor 7 on reduction valve 6, and pressure transducer 7 and carrier gas analysis module 8 are co-located in main frame 9.Reduction valve 6 and pressure transducer 7 are connected to main frame 9 by pressure sensing line 5, are provided with carrier gas analysis module in main frame 9, can by data upload to backstage.Operating personnel directly can also check nebulizer gas pressure and the gaseous tension after reduction valve in bottle from backstage.When being convenient to not go to scene, staff judges.
When whether judgment means lacks carrier gas, by the numerical value of nebulizer gas pressure table 3 and carrier gas delivery gauge 4 in external bottle, it is judged.
Sidewall due to casing 1 is provided with the view window 2 of observable nebulizer gas pressure, makes original all steel formula shell change the shell of the visual transparency window with plastic, transparent material into.During concrete enforcement, the material that view window 2 can choose the transparency such as glass, transparent plastic strong is made.During work, operating personnel directly can check nebulizer gas pressure and the carrier gas output pressure after decompression in bottle by view window 2.
Claims (2)
1. be convenient to the oil chromatography on-Line Monitor Device monitoring nebulizer gas pressure, comprise gas filling bottle, reduction valve (6) and pressure transducer (7); It is characterized in that: on the sidewall of casing (1), be provided with view window (2), the gas filling bottle that casing (1) is built-in is connected with nebulizer gas pressure table (3) and carrier gas delivery gauge (4) in bottle, in bottle, nebulizer gas pressure table (4) is by sense line (5) the Bonding pressure sensor (7) on reduction valve (6), and pressure transducer (7) and carrier gas analysis module (8) are all arranged in main frame (9); Reduction valve (6) and pressure transducer (7) are connected to main frame (9) by pressure sensing line (5); Main frame is provided with carrier gas analysis module in (9), can by data upload to backstage.
