Abstract
The utility model relates to the technical field of leak detectors, in particular to an SF6 quantitative leak detector. The SF6 quantitative leak detector comprises a display host, a metal pipe cavity, an air inlet, a sensor, an air pump and an air outlet. The metal pipe cavity is connected to the air inlet. The air inlet is connected to the sensor. The sensor is connected to the air pump. The air pump is connected to the air outlet. The sensor is connected to the display host. The SF6 quantitative leak detector is simple in integral structure. The result for detecting the indoor SF6 gas concentration in a power distribution device provided with SF6 equipment is accurate. When the SF6 gas concentration is more than 1000 ppm, measures can be taken in time, so that the safety of field workers can be ensured.
Description
Technical field
The utility model relates to a kind of leak locator, relates in particular to a kind of SF
6Quantitative leak detector.
Background technology
High pressure SF
6Its inside of switchgear is filled with SF
6Gas, SF
6Gas mainly is as a kind of insulation of excellence and arc-extinguishing medium and successfully be applied to high-voltage switch gear and equipment thereof in power industry, in high pressure, UHV (ultra-high voltage) and extra-high voltage field, and SF
6Gas almost becomes unique insulation and the arc-extinguishing medium of isolating switch and GIS.
But in switch breaking operation process, under arcing, corona, spark discharge and factors such as shelf depreciation, high temperature, SF
6Gas can decompose, and its decomposition can become the corrosivity electrolyte after running into moisture, and some high toxicity analyte wherein is like SF

2F
2, S
2F
10, SOF
2, HF and SO
2, their Diazolidinyl Ureas, mucous membrane if soakage is big, also can cause dizziness and pulmonary emphysema, even the causing death.Be filled with SF
6The equipment of gas is installed in indoor mostly, and circulation of air speed is relatively slow, if SF
6Gas will be in case leakage will be difficult for distributing SF in indoor deposition
6Gas itself is again colorless and odorless, leaks the back and is difficult for being realized.In addition because SF
6The proportion of gas is big than oxygen, is deposited on low sheaf space often, causes local anoxic easily, and the people is suffocated.Will cause great potential safety hazard to the field personnel like this.
Summary of the invention
The technical matters that the utility model will solve is: SF
6The leakage of gas and decomposition can cause great potential safety hazard to the field personnel, and a kind of SF is provided
6Quantitative leak detector.
In order to overcome the defective that exists in the background technology, the utility model solves the technical scheme that its technical matters adopted and is: this SF
6Quantitative leak detector comprises demonstration main frame, metal tube chamber, air intake opening, sensor, aspiration pump and gas outlet; Said metal tube chamber connects air intake opening, air intake opening connects sensor, sensor connection aspiration pump; Aspiration pump connects the gas outlet, and sensor connects and shows main frame.
The beneficial effect of the utility model is: this SF
6The quantitative leak detector one-piece construction is simple, detects SF is housed
6The indoor SF of the power distribution equipment of equipment
6Gas concentration, testing result is accurate, works as SF
6Gas concentration can in time be taken measures during greater than 1000ppm, has guaranteed field personnel's potential safety hazard.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model.
Embodiment
Fig. 1 is the structural representation of the utility model; Comprise among the figure and show main frame, metal tube chamber, air intake opening, sensor, aspiration pump and gas outlet; Said metal tube chamber connects air intake opening, air intake opening connects sensor, sensor connection aspiration pump; Aspiration pump connects the gas outlet, and sensor connects and shows main frame.
Metal tube chamber inside carries pump-line, SF
6Gas is drawn into by the metal tube chamber, and through air intake opening, flows through sensor is bled through aspiration pump again, discharges instrument by the gas outlet at last, and sensor will flow through SF
6Density information be transferred to the demonstration main frame.If SF
6Gas concentration can in time be taken measures during greater than 1000ppm, has guaranteed field personnel's potential safety hazard.
This SF
6The quantitative leak detector one-piece construction is simple, detects SF is housed
6The indoor SF of the power distribution equipment of equipment
6Gas concentration, testing result is accurate, works as SF
6Gas concentration can in time be taken measures during greater than 1000ppm, has guaranteed field personnel's potential safety hazard.
