Abstract
The invention relates an air extracting device for an SF6 gas leakage monitoring alarm. A housing is internally provided with a motor cabin which is internally provided with a motor, a motor transmission shaft is provided with an air extracting fan, the left side end of the motor cabin is fixedly connected with a gas sensor for monitoring SF6 gas in air, the motor cabin is internally provided with a control switch for controlling the motor to work, the signal input/output end of the control switch is electrically connected with the signal output end of the gas sensor, an air collecting pipe communicated with an inner cavity of the housing is arranged at the right side opening end of the housing, the right side of the air collecting pipe is fixedly connected with a connecting pipe communicated with the air collecting pipe, and a plurality of air guide pipes communicated with the air collecting pipe are formed on the left side face of the housing. According to the air extracting device for the SF6 gas leakage monitoring alarm provided by the invention, as the sensor capable of not only initially detecting SF6 gas, but also controlling the air extracting fan as well as the air collecting device for enhancing the air density are arranged on the housing, the false alarm rate of the alarm as well as the energy consumption is greatly reduced.
Description
Technical field
The present invention relates to a kind of air extractor for SF6 gas leakage monitoring alarm.
Background technology
For usually detecting SF6 gas, special SF6 gas leakage monitoring alarm can be used, by the electric current that inside is constant, just can learn whether the leakage of SF6 exceeds standard.But electric jamming or other factors can affect the size of current between electrode sometimes, easily cause wrong report phenomenon, and common SF6 gas leakage monitoring warning device is by cannot initiatively by the testing calibration sensor of extraneous air suction alarm inside, detection precision is promoted by lifting air concentration and repeated detection, if but keep bleeding state, again very not energy-conserving and environment-protective always.
Summary of the invention
The technical problem to be solved in the present invention is: for solving above-mentioned Problems existing, provides a kind of air extractor for SF6 gas leakage monitoring alarm, and solving common alarm does not have Multiple detection and calibrating installation, causes the problem that rate of false alarm is very high.
The technical solution adopted for the present invention to solve the technical problems is: a kind of air extractor for SF6 gas leakage monitoring alarm, comprise housing, in housing, there is motor room, motor is provided with in motor room, motor transmission shaft is provided with the fan for bleeding, motor room left-hand end is fixedly connected with the gas sensor for monitoring SF6 gas in 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 be connected with housing cavity, the connecting pipe be connected with duct set is fixedly connected with on the right side of duct set, housing left surface offers 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 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 invention has the beneficial effects as follows, air extractor for SF6 gas leakage monitoring alarm of the present invention can not only Preliminary detection SF6 gas by being provided with on housing, the sensor of extraction fan and the wind-drive device for promoting atmospheric density can also being controlled, greatly reducing the reduction energy consumption of alarm rate of false alarm.
