The air extracting device for the SF6 gas leakage monitoring alarm greatly reduces the false alarm rate of the alarm and reduces the energy consumption through arranging the sensor and the air collecting device used for improving the air density, wherein the sensor not only can preliminarily detect the SF6 gas, but also can control the air extracting fan.
Description
Technical field
The utility model relates to a kind of air extractor for SF6 gas leakage monitoring alarm.
Background technology
For common detection SF6 gas, can use special SF6 gas leakage monitoring alarm, by the constant electric current in inside, just can learn whether the leakage of SF6 exceeds standard.But electric field interference sometimes or other factors can affect the size of current between electrode, easily cause wrong report phenomenon, and common SF6 gas leakage monitoring warning device is by cannot be initiatively by the testing calibration sensor of extraneous air suction alarm inside, promote detection precision by promoting air concentration and repeated detection, if but keep bleeding state, again very not energy-conserving and environment-protective always.
Utility model content
The technical problems to be solved in the utility model is: for solving the problem of above-mentioned existence, provide a kind of air extractor for SF6 gas leakage monitoring alarm, solving common alarm does not have Multiple detection and calibrating installation, causes the problem that rate of false alarm is very high.
The utility model solves the technical scheme that its technical matters adopts: a kind of air extractor for SF6 gas leakage monitoring alarm, comprise housing, in housing, there is motor room, in motor room, be provided with motor, on motor transmission shaft, be provided with the fan for bleeding, motor room left-hand end is fixedly connected with the gas sensor that is useful on SF6 gas in monitoring air, motor room inside is provided with the gauge tap for controlling machine operation, the signal of gauge tap is come in and gone out and is held the signal output part with gas sensor to be electrically connected, gas sensor left surface and housing left surface are positioned at same plane, housing right openings, housing right openings end is provided with the duct set with housing intracavity inter-connection, duct set right side is fixedly connected with the connecting pipe being connected with duct set, on housing left surface, offer the guide duct that several are connected with duct set.
Further, hull outside face is provided with the coupling arrangement for housing being fixed on to alarm inside.
Further, coupling arrangement is identical with body case of annunciator thickness to the distance of housing left surface.
Further, duct set diameter diminishes from left to right gradually.
The beneficial effects of the utility model are, air extractor for SF6 gas leakage monitoring alarm of the present utility model can not only Preliminary detection SF6 gas by being provided with on housing, can also control the sensor of extraction fan and for promoting the wind-drive device of atmospheric density, greatly reduce the reduction energy consumption of alarm rate of false alarm.
Brief description of the drawings
