Before the sulfur hexafluoride sampling, earlier ST to be vacuumized operation, should make it connect external power supply when ST vacuumizes and carry out auxiliary heating.Concrete steps are following:
(1), external equipment connector 2 usefulness flexible pipes are connected with the air intake opening of vacuum pump and lock, guarantee impermeability;
(2), take out circumscripted power line, an end inserts in supply socket 15, the other end of ST and plugs suitable external power supply;
(3), vacuum pump connects suitable power source, start vacuum pump and move to stable;
(4), slowly open vacuum pump air intake opening switch, connecting line is vacuumized, according to the impermeability of vacuum tightness situation of change inspection connecting line;
(5), constant temperature switch 13 is pulled to " vacuumize shelves ", the 17 pairs of sampling jars of heating element 5 in ST this moment heat with Drexel bottle 4;
(6), then operating grip 11 is threaded to " gas washing " shelves; External equipment connector 2, wireway 7, multiport valve 6, wireway 8 and Drexel bottle 4 are communicated with; Drexel bottle 4 is vacuumized, and when about certain hour final vacuum degree reached regulation, Drexel bottle 4 vacuumized and finishes;
(7), again operating grip is revolved 11 to " sampling " shelves; External equipment connector 2, wireway 7, multiport valve 6, wireway 9 and sampling jar 5 are communicated with, and sampling jar 5 are vacuumized, when pressure vacuum gauge is shown as authorised pressure; Continue to take out a few minutes to vacuum tightness again when dropping to the authorised pressure left and right sides; Then sampling jar 5 vacuumizes and finishes, and then operating grip 11 is rotated to " closing shelves ", closes vacuum pump again;
(8), ST vacuumizes and should external equipment connector 2 be put dustproof pipe cap after qualified, with ST surface wiped clean, and ST is positioned in the suitcase;
(9), application of vacuum finishes, and in time fills in the vacuum pumping release, puts into the clip closed condition.
Vacuumize and can carry out test of hydrogen fluoride gas colorimetric and gas sample operation after operation is accomplished, concrete steps are:
(1) correctly connects the external equipment connector 2 of sample tap to the ST of sulfur hexafluoride electrical equipment, guarantee impermeability;
(2), new hydrogen fluoride color comparison tube 25 is carried out opening and cut off processing;
(3), will be the hydrogen fluoride color comparison tube 25 of opening be installed on test tube device 23 and the following test tube device 24, the direction of arrow of hydrogen fluoride color comparison tube 25 is down during installation.Hydrogen fluoride color comparison tube 25 is disposable, holds mouthful the back successfully and installs and uses, and new hydrogen fluoride color comparison tube 25 need be installed when using at every turn at once;
An end that will not have arrow when (4), hydrogen fluoride color comparison tube 25 is installed is put in down in the gas passage 51; Light downwards pressure of hand; Following motion bar 49 overcomes the elastic force of the 4th spring 52, and following motion bar 49 lower end unseat the valve cores 50 make down gas passage 51 be communicated with Drexel bottle 4;
The another hand upwards gently draws test tube handle 26; Motion bar 45 overcomes the elastic force of the 3rd compression spring 47 in the drive, and hydrogen fluoride color comparison tube 25 is vertically placed, and unclamps test tube handle 26 again; Hydrogen fluoride color comparison tube 25 arrow ends are put in the gas passage 46; Pinching hydrogen fluoride color comparison tube 25 middle part left rotation and right rotation with finger then, that it is aligned is straight, makes air-flow guiding arrow outwardly, and then hydrogen fluoride color comparison tube 25 installs;
(5), operating grip 11 is threaded to " hydrogen fluoride test shelves "; External equipment connector 2, wireway 7, multiport valve 6, wireway 10 and hydrogen fluoride color comparison tube 25 are communicated with; Slowly open external equipment sample tap valve then and kind gas is arranged through getting final product; Throttling valve 27 plays and vacuumizes or gas keeps constant rate under certain pressure when taking a sample effect; Timing is a few minutes approximately, promptly accomplish hydrogen fluoride test (need not carry out the hydrogen fluoride test like the scene of taking a sample, operating grip 11 directly is threaded to " gas washing shelves " and carry out gas washing and get final product);
(6), with operating grip 11 dextrorotations to " gas washing shelves ", after timing some seconds, accomplish gas washing (carried out the hydrogen fluoride test like the scene of taking a sample, need not carry out gas washing, then can directly handle be threaded to the sampling shelves and carry out sampling operation);
(7), (or carrying out hydrogen fluoride test back) behind the gas washing; Operating grip 11 is threaded to " sampling shelves "; When ST upward pressure table shows that the demonstration reading of the electrical equipment upward pressure table of being taken a sample with quilt is identical; 11 dextrorotations of ST operating grip to " close shelves " position, are closed sampling air intake valve on the electrical equipment then, removed the sampling inlet pipe connection;
(8), take behind kind gas ST external interface to be put dust cap, with ST surface wiped clean, be positioned in the suitcase;
(9), gas sample finishes, with the sampling record card of filling in, put into the clip closed condition.
After the sampling, the chamber gas appearance stratographic analysis step that experimentizes is following:
(1), is connected through decompressor in the middle of the external equipment connector 2 that will fill kind gas and the chromatograph interface and locks the assurance impermeability;
(2), the socket of ST 15 connects the 220V power supplys, closed power switch, and constant temperature switch 13 pulled as for " chromatogram shelves " state;
(3), the chromatograph preheating, about about 30 minutes of timing, chromatograph is in normal operating conditions;
(4), press the non-return button 33 of the stratographic analysis indication on the ST; Non-return button 33 moves down through the elastic force that non-return connecting link 38 drive register pins 34 overcome second compression spring 40; Register pin 34 moves down with oblique tongue 42, and when oblique tongue 42 was lower than the dial plate 41 of operating grip 11 bottom surfaces, register pin 34 no longer stopped dial plate 41; So just can operating grip 11 be threaded to counterclockwise " sampling shelves " position, can carry out stratographic analysis;
(5), after the laboratory chromatogram detects and accomplishes; Successively with ST constant temperature switch 13 pull as for " close shelves ", operating grip 11 dextrorotations to " close shelves "; Break off the ST power switch, print and preserve the detection data, close the chromatograph switch at last, stratographic analysis is accomplished;
(6), stratographic analysis should put pipe cap with the ST external interface after finishing, with ST surface wiped clean, be positioned in the suitcase.
The present invention in use should be noted that following item:
(1), connecting tube transpassivation, protective treatment between inner each parts of ST, forbid dust, dirty entering.
(2), keep ST surface clean, clean and tidy, answer wiped clean after each the use, and in time be put in the suitcase.
(3), when ST does not use, external equipment connector 2 should in time put the sealing and dustproof cap, loads onto used hydrogen fluoride color comparison tube 25 at last test tube device 23 and following test tube device 24.
(4), ST belongs to cleaning apparatus, should note waterproof and dustproof and protection against the tide.
(5), ST vacuumizes and the external power supply of should pegging graft when carrying out kind complexion analysis of spectrum, notices that constant temperature switch 13 selects shelves, must not make a mistake and mix up.
(6), ST for a long time not the clean dry nitrogen of time spent application of pure wash, and the nitrogen that charges into the certain pressure clean, dry in the sampling jar is sealed up for safekeeping.
(7),, gas-holder or steel cylinder should take care when being carried out high-pressure sampling.
