Abstract
The utility model discloses a sulfur hexafluoride leakage alarm controller. The technical scheme includes that information received by a collection unit enters an integrated package via a sampling circuit, the integrated package processes and inputs the information to an execution unit which then sends out audible, visual and language alarm and simultaneously starts a ventilation facility to dilute leaked sulfur hexafluoride gas concentration in a workshop, and the gas is then exhausted out of the workshop, thereby achieving purposes of safety, hidden risk elimination, and avoidance of casualty, explosion and the like. The controller has the advantages of long service life, low energy consumption, high detection sensibility, low cost, and safety and reliability.
Description
Technical field
The utility model belongs to a kind of device that detects harmful gas in the minimum gas measuring appliance, sulfur hexafluoride leakage alarm controller.
Background technology
Transformer station's high-voltage board usable range is very wide, in long-term use, can produce the situation that sulfur hexafluoride gas leaks and take place, and sulfur hexafluoride with can be the very strong harmful gas of a kind of toxicity after the external world contacts.In time do not found if there is sulfur hexafluoride to leak in process of production, the electric arc that produces during combined floodgate very easily sets off an explosion, cause personal injury, its potential safety hazard is very fearful, therefore the detection of sulfur hexafluoride gas, the processing of reporting to the police are necessary, vast Hydraulic and Hydro-Power Engineering personnel are making great efforts to take measures, for the safe handling of transformer station's high-voltage board provides safeguard.
The utility model content
The purpose of this utility model provides a kind of energy and detects the on-the-spot sulfur hexafluoride leakage alarm controller of processing of also in time reporting to the police.
The technical solution of the utility model as shown in Figure 1, after adopting collector unit to receive the information of sulfur hexafluoride leakage, join by cable and sample circuit, sample circuit is joined by lead and integrated package, integrated package joins by lead and performance element, performance element is just sounded and audio alert, flashing light alarm, and in time starts open air exhaust facility elimination harm.
The utility model has the advantages that in transformer station's high-tension switch cabinet factory building, in case sulfur hexafluoride takes place to be leaked, hummer sends chimes of doom immediately, behind certain hour, promptly stop, then phonetic alarm just ceaselessly sends prompting repeatedly, flashlamp is also ceaselessly luminous simultaneously, the interior open air exhaust facility of factory building this moment starts, air in the factory building is carried out open air exhaust, make the gas concentration of leakage obtain dilution and discharge factory building, in time eliminate safe hidden trouble, avoid exploding and the generation of casualties and accident, treat the operator on duty arrive handle after, the sulfur hexafluoride leakage alarm controller just returns to original normal operating conditions.

Wherein: 1, collector unit 2, sample circuit 3, integrated package 4, performance element A, sensor Z, hummer J1, phonetic alarm J2, flashlamp J3, relay
Embodiment
The utility model is implemented by technique scheme, as shown in Figure 2, collector unit 1 and main sensors A adopt semiconductor probe TG832, by R3, R4, R5, R6 is sample circuit 2, integrated package 3 adopts 1904 to be negative circuit, has adopted hummer Z in the performance element 4, phonetic alarm J1, integrated package adopts WTB031 in the voice suggestion, flashlamp J2 and the open air exhaust equipment operation by relay J 3 control A.C. contactors controls etc.When sulfur hexafluoride gas leaks, semiconductor probe TG832 and sulfur hexafluoride gas react, and its element tissue is changed, and utilize this subtle change, amplify through shaping, and the startup warning device, make it send sound and light alarm, connect open air exhaust equipment, sulfur hexafluoride gas concentration in the diluent air, and the discharge factory building, eliminated potential safety hazard, guarantee personnel's life security.
The utility model long service life, energy consumption is low, and measurement range is 100 ~ 3000PPM, semiconductor probe sensitivity (resistance ratio) 0.15V.The utility model cost is low and safe and reliable.
