Description
Technical field
The utility model relates to a kind of device that SF6 equipment is carried out charged tonifying Qi.
Background technique
Owing to can involving the open and close of SF6 equipment valve in charged tonifying Qi process, because the defective in design and operator's operating habit is different, after inflation, SF6 equipment valve may be not closed completely, and what some crack was larger even can hear the sound of Leakage Gas.But when leakage was so unobvious, in electric substation, the noise of electric arc was larger, is difficult to judge whether leakage by the sense of hearing.
In the past after SF6 equipment is inflated, due to the defective of device and the complexity of substation field environment, make the valve of the discovering device that the maintainer can not be accurately and timely whether close tight, and need maintainer and operations staff repeatedly the scene to be verified, due to the zone that is charging operation, have certain person, power grid risk.If valve has leakage but in time not find, very likely cause equipment to control malfunctioning, make electrical network face huge risk, simultaneously the work about electric power personnel also there is great risk.
Therefore in the past charged making-up air device do not consider the function of this respect yet, namely judge whether to also have after valve closing and leak, perhaps further, can fundamentally address this problem.
The model utility content
The purpose of this utility model is to overcome the deficiency that prior art exists, and a kind of SF6 equipment Leakage Gas speed of can measuring accurately in real time is provided, and after gas charging valve leaks, and plays the device that SF6 equipment is carried out charged tonifying Qi of throttle down effect.
The purpose of this utility model is completed by following technical solution, it comprises that one can carry out to SF6 equipment the inflator of charged tonifying Qi, it is characterized in that adding on described inflator one in order to measure the flowmeter of SF6 Leakage Gas speed, in inflator, be provided with a gas charging valve that directly is connected with gas-charging connection; Described inflator is connected with described SF6 equipment by safety valve and crossover sub that gas ducting is connected with a capable of regulating switching path.
Described inflator also comprises a cross fitting, connecting gas charging valve, flowmeter and safety valve at least respectively, the check valve thimble of described safety valve inside be placed in a straight line on, the outer outside thimble split setting that is being connected knob, and the front end of described check valve thimble contacts with the joint of SF6 equipment, and can make the check valve thimble be in zero stroke, half trip and full stroke three positions in valve body.
Also be connected with outlet valve on described cross fitting; The joint contacting point of check valve thimble and SF6 equipment is provided with groove shapes in described safety valve, and the both sides of groove contact with the anchor ring of SF6 device junction.
Whether the utility model can be measured SF6 equipment accurately has and leaks and leakage rate, timely handling failure, ensure electrical network fully, have a dismounting simple, easy to use, the characteristics such as safe and reliable.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is safety valve structure schematic diagram described in the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is done detailed introduction: shown in Figure 1, the utility model comprises that one can carry out to SF6 equipment the inflator of charged tonifying Qi, add one on described inflator in order to measure the flowmeter 3 of SF6 equipment Leakage Gas speed, in inflator, be provided with a gas charging valve 5 that directly is connected with gas-charging connection 4; Described inflator is connected with described SF6 equipment by safety valve 7 and crossover sub 8 that gas ducting 6 is connected with a capable of regulating switching path.
Described inflator 2 also comprises a cross fitting 9, it is connecting at least respectively gas charging valve 5, flowmeter 3 and safety valve 7, the check valve thimble 10 of described safety valve 7 inside be placed in a straight line on, the outer outside thimble 12 split settings that are being connected knob 11, and the front end of described check valve thimble 10 contacts with the crossover sub 8 of SF6 equipment, and can make check valve thimble 10 be in zero stroke, half trip and full stroke three positions in valve body, as shown in Figure 2.
Also be connected with outlet valve 13 on cross fitting 9 described in the utility model; Crossover sub 8 contacting points of the interior check valve thimble of described safety valve 7 10 and SF6 equipment are provided with groove shapes, and the both sides of groove contact with the anchor ring of SF6 device translates joint 8.
In fact the utility model reequips safety valve, and has considered multiple demand and following use function:
1, the thimble of split-type structural: the outside thimble of valve and inner check valve thimble can not be made whole form, otherwise also and then rotation of inner check valve thimble during handle with sleeve, if the check valve surface of contact of device junction is not level, can form chain reaction, and then rotate together easily gas leakage when closing; And that we make is split type, and inner check valve thimble along continuous straight runs moves, and does not have this problem.
2, the Safety function of inner check valve thimble: the place that the thimble of inner check valve contacts with device junction, we have been designed to the form of groove with it: the check valve of inner check valve pushing equipment joint inwardly moves, if hard-core words may push away the check valve of equipment dark so that equipment failure occur; And after we are designed to form of grooves with it; the groove middle body has played the effect of pushing equipment joint check valve; the both sides of groove are with after the anchor ring of device junction contacts; played the effect of snap ring; make inner check valve can't continue motion, reached the target of protection device junction check valve.
3, the multiple effect of valve: old inflator in case and equipment connect, the check valve of apparatus body just is opened, if the valve tightness on inflator is bad, easily causes leakage, nor facilitate, it is carried out the measurement of gas leakage.The Valve joint of our design is compared with the past a very large improvement:
The utility model is after inflator connects up, and the valve of apparatus body can not be opened.Thus, formed the dual fail-safe of apparatus body valve, inflator valve twice valves, if leakage has occured the apparatus body valve, the inflator valve can play the effect of Leakage prevention;
The inner thimble of safety valve has three positions: zero stroke, half trip, full stroke.
During zero stroke, safety valve cuts out, and its effect has played the effect of dual fail-safe as described in (1);
When the half trip, safety valve is opened, but the valve of apparatus body also is in closed condition, at this moment by flowmeter just very easily measuring equipment body valve whether close tight;
During full stroke, safety valve is opened, and the apparatus body valve is also opened, and can inflate.
