Abstract
The utility model relates to an inspection device, and more specifically, relates to an imager device for inspecting SF6 gas leakage. The imager device for inspecting SF6 gas leakage comprises an automatic injection pump, an injector, and a dentistry needle. The injector is connected with the automatic injection pump through a rubber hose, and the dentistry needle is connected with the injector in a clamping way. The imager device is advantaged in that with the inspection device, not only sensitivity inspection requirement of the SF6 gas leakage imager can be achieved, but also different leakage quantity of SF6 devices can be simulated, thereby improving leak detection level. The imager device is of important significance for ensuring safe operation of electric equipment.
Description
Technical field
The utility model relates to a kind of inspection machine, specifically relates to a kind of SF that is used to check
6Gas leaks the device of imager.
Background technology
SF
6The arc extinguishing of gas and insulating property and its pressure dependence are close, and when pressure reached about 0.3MPa, its insulating property and insulating oil were suitable.Keep good arc extinguishing and insulating property, must keep enough pressure.SF
6The leakage of electrical equipment will cause SF
6The decline of gaseous tension reduces its electric property, and the moisture in the environment will be infiltrated from outside to inside, threaten equipment safe operation, cause the pollution of environment.For carrying out SF
6The leakage monitoring work of electrical equipment, we have introduced a SF
6Gas leaks imager; When this instrument former should surveyed area exists SF6 gas to leak,, can weaken sharp so reflex to the IR energy of checkout equipment this moment because SF6 gas has the strong absorption effect to IR; SF6 gas is shown as black smoke on equipment; And along with gas concentration changes, blackness is also different, the detection sensitivity of instrument: 0.001mL/s SF
6,But this instrument belongs to domestic and international advanced technology, domestic check, the method for calibration of setting up maturation as yet.
Summary of the invention
The purpose of the utility model provides a kind of SF that is used to check
6Gas leaks the pick-up unit of imager.
The utility model is a kind of to be used to check SF
6The device that gas leaks imager is achieved through following technical proposals: a kind ofly be used to check SF
6The device that gas leaks imager comprises automatic syringe pump, syringe, dentistry syringe needle, and described syringe is connected with automatic syringe pump through rubber hose, and the dentistry syringe needle is connected with the syringe clamping.
The utility model is a kind of to be used to check SF
6The device that gas leaks imager has following beneficial effect compared with prior art: draw purity 99.99%SF with the 50mL syringe
6Gas 40mL installs 5# dentistry syringe needle, and it is 3.6 mL/h that automatic syringe pump injection rate is set, and starts syringe pump, 5# dentistry syringe needle ejection SF
6Gas flow rate is 0.001mL/s, satisfies SF
6The requirement of gas leak detection imager sensitivity test.
Through this verifying attachment, not only can realize SF
6Gas leaks imager sensitivity and detects requirement, can simulate SF simultaneously
6The leakage rate that equipment is different improves the Leak Detection level, and is significant to the safe operation that guarantees electrical equipment.

Be used to check SF below in conjunction with accompanying drawing and embodiment to the utility model is a kind of
6The pick-up unit technical scheme that gas leaks imager further describes.
As shown in Figure 1, the utility model is a kind of to be used to check SF
6The device that gas leaks imager comprises automatic syringe pump 1, syringe 2, dentistry syringe needle 3, and described syringe 1 is connected with automatic syringe pump 1 through rubber hose, and dentistry syringe needle 3 is connected with syringe 2 clampings.
The injection rate setting range of described automatic syringe pump 1 is that 0.1mL/h～600 mL/h are adjustable.
Select 2 one of 50mL syringes for use, 3 one at 5# dentistry syringe needle, syringe pump is 1 one automatically, and its injection rate setting range is that 0.1mL/h～600 mL/h are adjustable, by assembling as shown in Figure 1.
Method of operating: draw purity 99.99%SF with the 50mL syringe
6Gas 40mL installs 5# dentistry syringe needle, and it is 3.6 mL/h that automatic syringe pump injection rate is set, and starts syringe pump, 5# dentistry syringe needle ejection SF
6Gas flow rate is 0.001mL/s, satisfies SF
6The requirement of gas leak detection imager sensitivity test.
Described 3.6ml/h is 0.001ml/s.
