Abstract
The utility model discloses a kind of SF6 storage pressure detection device, its main points are that it comprises the housing that two ends are respectively equipped with the push-in inlet, outlet of bolt; Inlet, outlet is interconnected by pipeline; Inlet, outlet place is respectively equipped with the inlet, outlet valve be interconnected with pipeline; Pipeline is communicated with an electronic pressure meter, and between inlet, outlet valve; Be provided with pointer gear in electronic pressure meter, and the rotating shaft of pointer gear is fixed with lever; The two ends of lever are respectively equipped with the bellows with pipeline connection.Because two ends adopt the push-in inlet, outlet of bolt to connect, during inflation, two ends inlet, outlet valve is all opened, controlled by electronic pressure meter reading, when Pressure Drop is to throttle down during 0.1Mpa, stop inflation; When carrying out one-sided Pressure testing, only need by this side valve open, opposite side is closed, and carry out reading, electronic pressure meter carries out numerical monitor, and Security is high, accurate measurement.
Description
technical fieldthe utility model belongs to storage pressure detection technique field, is specifically related to a kind of storage pressure detection device for SF6 high voltage electric equipment.
background techniquein prior art, in SF6 high voltage electric equipment gas replenishment process, if during the pressure balance of the pressure in SF6 gas cylinder and charger, the gas in gas cylinder can not be charged in air chamber and there will be residue; And prohibit the use after SF6 gas cylinder internal pressure is reduced to 0.1MP, reason is that bottom of steel cylinder residual gas impurity is more, the quality of device interior gas can be affected after pouring, but the inflating gas cylinder reducing valve pressure gage used at present, because range is larger, scale skewness, instruction inaccuracy, when after Pressure Drop to certain limit, can not pin-point reading; After SF6 equipment insufflation gas, density monitor on apparatus body can show internal pressure, but according to the work statistic in former years, we find that density monitor exists the inaccurate situation of instruction, cause the alarm signal sent out pressure by mistake and reduce, when personnel on site is inflated to rated pressure, actual internal pressure exceedes rated pressure, long-play can cause density monitor casing rupture, glass outer bursts, the personal safety of serious threat Field Force.
summary of the inventionthe purpose of this utility model solves prior art to there is the technical problem of measuring inaccurate and poor stability, provides a kind of SF6 storage pressure detection device, to overcome the deficiencies in the prior art.
To achieve these goals, a kind of SF6 storage pressure of the utility model detection device, its main points are that it comprises the housing that two ends are respectively equipped with the push-in suction port of bolt and air outlet; Described suction port and air outlet are interconnected by pipeline; Described suction port and air outlet place are respectively equipped with the air intake valve and valve of giving vent to anger that are interconnected with pipeline; Described pipeline is communicated with an electronic pressure meter, electronic pressure meter is at air intake valve and give vent to anger between valve; Be provided with pointer gear in described electronic pressure meter, and the rotating shaft of pointer gear is fixed with lever; The two ends of described lever are respectively equipped with the bellows with pipeline connection.
The utility model structure is simple, easy to use, because two ends adopt the push-in inlet, outlet of bolt to connect, during inflation, two ends inlet, outlet valve is all opened, controlled by electronic pressure meter reading, when Pressure Drop is to throttle down during 0.1Mpa, stop inflation; When carrying out one-sided (gas cylinder side or air chamber side) Pressure testing, only need by this side valve open, opposite side is closed, and carry out reading, electronic pressure meter carries out numerical monitor, and Security is high, accurate measurement.The utility model solves prior art and measures technical problem that is inaccurate and poor stability.
accompanying drawing explanationfig. 1 is the utility model inflation in-site modeling figure;
Fig. 2 is the utility model structural representation;
Fig. 3 is the utility model electronic pressure meter internal structure schematic diagram.
In figure 1, SF6 gas cylinder 2, inflation connecting tube 3, SF6 electrical equipment 4, electronic pressure meter 5, suction port 6, air outlet 7, air intake valve 8, valve 9 of giving vent to anger, pipeline 10, pointer gear 11, rotating shaft 12, lever 13, bellows 14, dial 15, housing
embodimentwith reference to Fig. 1, Fig. 2 and Fig. 3, the utility model it comprise the housing 15 that two ends are respectively equipped with the push-in suction port 5 of bolt and air outlet 6; Described suction port 5 and air outlet 6 are interconnected by pipeline 9; Described suction port 5 and air outlet 6 place are respectively equipped with the air intake valve 7 and valve 8 of giving vent to anger that are interconnected with pipeline 9; Described pipeline 9 is communicated with an electronic pressure meter 4, electronic pressure meter 4 is at air intake valve 7 and give vent to anger between valve 8; Be provided with pointer gear 10 in described electronic pressure meter 4, and the rotating shaft 11 of pointer gear 10 is fixed with lever 12; The two ends of described lever 12 are respectively equipped with the bellows 13 be communicated with pipeline 9.
During use, with inflation connecting tube 2, push-in to SF6 gas cylinder 1 and SF6 electrical equipment 3 and bolt suction port 5 is communicated with air outlet 6, opens the inlet, outlet valve 7,8 at two ends, controlled by electronic pressure meter 4 reading, when Pressure Drop is to throttle down during 0.1Mpa, stop inflation; When carrying out one-sided (gas cylinder side or air chamber side) Pressure testing, only need by this side valve open, opposite side is closed, and carries out reading; Electronic pressure meter working principle is the SF6 gas cylinder be communicated with SF6 gas in circuit breaker be sealed in outside bellows 13, is rotated by the lever 12 being the strong point with rotating shaft 11, compares with the calibrating gas bag be sealed in outside bellows 13; During detection, outside bellows 13, the pressure of SF6 gas will increase, lever 12 will be promoted 11 rotate around the shaft, pointer gear 10 is along with rotation simultaneously, pointer is made to carry out reading on dial 14, simultaneously according to pressure size, pressure cell sensed pressure size the display device carrying out the backward instrument of corresponding digital-to-analog conversion process sends display command, and can synchronously to accessed system send corresponding data information, realize force value digital displaying function.
The utility model has the advantage of accurate detected pressures; booster action is served to engineering construction and daily defect elimination; apply this device greatly to reduce gas cylinder impurities at bottom and pour the risk that air chamber causes gas purity low; the staff carrying out tonifying Qi defect elimination can also be played a protective role; find plenum interior pressure Problems existing in advance, prevent danger field personnel damaged because the instruction of equipment pressure gauge is forbidden the air chamber caused to overcharge.
