Description
Technical field
The utility model relates to a kind of detection alarm system, in particular, relates to the online detection alarm of a kind of SF6 gas system.
Background technology
In power industry, SF6 gas is widely used in the indoor electric appliance equipment.Yet SF6 gas inevitably can leak.When SF6 gas reaches finite concentration, can cause certain injury to the staff in the switchgear building healthy.When the SF6 gas that leaks reached the protection limit, major accident can take place.Therefore, in switchgear building, need to install the SF6 detection system.Existing SF6 detection system uses sensor to take a sample.Because sensor is subjected to the influence of environment temperature, humidity bigger, often produce wrong report, rate of false alarm height.And the serviceable life of sensor is short, needs often to change, and has increased use cost.
The utility model content
The utility model is in order to overcome weak point of the prior art, and providing a kind of can detect in real time and report to the police SF6 gas, highly sensitive, the online detection alarm of the SF6 gas system that use cost is low.
The utility model is achieved through the following technical solutions:
The online detection alarm of a kind of SF6 gas system, it is characterized in that, comprise monitoring host computer, SF6 leakage alarm sampling module, laser type SF6 leakage alarm analysis module, controller of fan and alarm, described monitoring host computer is connected with controller of fan, alarm and laser type SF6 leakage alarm analysis module respectively, and described controller of fan is connected with blower fan; Described SF6 leakage alarm sampling module comprises electromagnetic pump and many sampling pipes, described electromagnetic pump is connected with many sampling pipes respectively, and described laser type SF6 leakage alarm analysis module is connected with SF6 leakage alarm sampling module by communication modes and gas transmission pipeline.Described monitoring host computer respectively with place switchgear building infrared sensor outdoors and switchgear building outdoors attention display be connected.
Described monitoring host computer is connected with remote control center.
Be provided with filtrator in the described sampling pipe.
The internal diameter of described sampling pipe is 2-8mm.
Described monitoring host computer is connected with the humidity detection module with the oxygen monitoring module respectively.
The utlity model has following technique effect:
1. the online detection alarm of SF6 gas of the present utility model system takes a sample by sampling pipe, directly detects check point, measures rapid more, accurate, highly sensitive.And, because the sampling pipe internal diameter is little, can replace pipeline gas rapidly.
2. the mode that the online detection alarm of SF6 gas of the present utility model system takes a sample by laser technology, active realizes the check and analysis to SF6 gas, can effectively overcome the wrong report that on-the-spot interference and sensor drift cause, and is highly sensitive.
3. the online detection alarm of SF6 gas of the present utility model system does not use sensor to detect, and avoids more emat sensor, and use cost is low.
