Fig. 2 is the module map of the removable sulfur hexafluoride sniffer of the present invention.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present invention is described.
As shown in Figure 1, the present invention has explained a kind of removable sulfur hexafluoride sniffer, and this device comprises dolly 1, is arranged on the gas sensor 2 in the dolly 1, and hand-held collector 3.
Wherein gas sensor 2 adopts sulfur hexafluoride and oxygen level double gas sensors.It comprises oxygen level sensor and sulfur hexafluoride sensor; Oxygen level sensor adopts Japan or German import electrochemical product, and can arrive 5 years serviceable life, and investigative range is between 14% ~ 26%; When oxygen content is lower than 18.6%, send alerting signal, can satisfy the requirement of this device.The sulfur hexafluoride sensor adopts the sensor of high-voltage corona mode, and it comprises a metallic cavity, and is arranged on the probe in the cavity; Leave a clearance for insulation between probe and the cavity; When between its two poles of the earth, adding high-tension electricity point discharge can take place, promptly between the gap, form corona field, when the insulating property (properties) of gas in the air changes; The room electric weight of this corona field can sharply change; Variable quantity through detecting discharge current contains the variable quantity of insulating gas concentration in can detecting air, when the variable quantity that sensor detects this concentration arrives the limit value of 1000ppm, sends alerting signal.Gas sensor 2 is gone back circuit and is connected with wireless communication line 21, sets up communication through this wireless communication line 21 with hand-held collector 3 and is connected.
