Description
Technical field
The utility model relates to SF6Gas leakage detection device technical field, especially a kind of cooperation SF6Leakage alarm dress
Set the collector box that tester uses.
Background technique
Due to SF6The verification of gas leakage warning device needs the SF of a variety of various concentrations6And O2Calibrating gas carries more
The calibrating gas of kind concentration is extremely inconvenient to scene, and also unrealistic, this makes power department that can not carry out SF6Gas leakage alarm
The field-checking of device results in most SF6Gas leakage warning device often issues false alarm letter in the process of running
Number or device failure is unable to operate normally alarm, become a kind of ornaments of substation, can not really play to people
The protective effect of body health has buried great security risk for enterprise's production.
With the continuous development of distribution technology, SF6Gas leakage warning device tester obtains promotion and application, uses school
Instrument is tested to SF6Gas leakage warning device, which verify, can avoid carrying a large amount of SF6Standard Gases and dilution gas cylinder, have letter
List fast and automatically changes the features such as degree is high, is SF6The field-checking work of gas leakage warning device provides greatly just
Benefit.
SF6Gas leakage warning device tester passes through mass flowmenter for high concentration SF6Calibrating gas mixes with air,
It is diluted to the various concentration SF needed6Calibrating gas and oxygen.When field-checking, by SF6Gas leakage warning device tester gas
The outlet of the gas-guide tube of body output end is directed at SF6The detection probe of gas leakage warning device, the calibrating gas admittance gas of preparation
Pipe outflow, can be dispersed into air rapidly, to be caused in the testing result and gas-guide tube of detection probe by diluting in air
Real gas concentration is inconsistent, is not able to satisfy verification SF6The demand of gas leakage warning device accuracy and repeatability.
Utility model content
The utility model discloses a kind of cooperation SF6The collector box that leakage alarming device tester uses, for detecting
When cover on SF6The periphery of gas leakage warning device detection probe, meets SF6School of the gas leakage warning device to gas concentration
Requirement is tested, SF can be greatly improved6The accuracy of gas leakage warning device tester inspection work.
To achieve the above object, the technical solution of the utility model are as follows:
A kind of cooperation SF6The collector box that leakage alarming device tester uses, including box body, the box body one side setting
There is air inlet, the other side is provided with gas outlet, and bottom edge is enclosed with rubber ring.
Further, counterweight is fixed on the top surface of the box body.
It preferably, further include handing in hand, described hand in hand is arranged on box body.It is furthermore preferred that the counterweight is with respect to box body top
The center line symmetrical setting in face has two pieces, and the both ends handed in hand are separately fixed above two pieces of counterweights.
Preferably, the size and SF of the gas outlet6The route of leakage alarming device tester matches.
Preferably, the air inlet edge wrap has a circle rubber sleeve, is provided with through-hole and air guide among the rubber sleeve
Pipe inlet end matches.
Above-described cooperation SF6The collector box that leakage alarming device tester uses, when use, cover the collector box
SF6Gas leakage warning device detection probe, then by by SF6Gas leakage warning device tester gas output end is led
Tracheae is inserted into air inlet, is passed through calibrating gas by air inlet, and calibrating gas gradually fills in collector box, after 5 ~ 7min,
SF in collector box6Gas concentration reaches the 95% of standard gas concentration, meets SF6Gas leakage warning device is to gas concentration
Verification requires, to improve the accuracy of detection, while can also obtain detection repeatability very well.
Detailed description of the invention
Fig. 1 is the schematic perspective view of the utility model.
Fig. 2 is the using state structure diagram of the utility model.
In figure, gas outlet 1, box body 2 hands in hand 3, counterweight 4, air inlet 5, rubber ring 6, SF6The inspection of gas leakage warning device
Probing head 7, gas-guide tube 8.
Specific embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail, but the protection scope of the utility model is unlimited
In following embodiment.
A kind of cooperation SF6The collector box that leakage alarming device tester uses, as shown in Figure 1, including box body 2, box body 2 one
Side is provided with air inlet 5, and the other side is provided with gas outlet 1, and bottom edge is enclosed with rubber ring 6, and box body 2 is can cover SF6
It gas leakage warning device tester detection probe and remains with certain gas mobile space and is advisable, rubber ring 6 can make box body 2
It can be preferably affixed on the periphery bearing for placing tester detection probe, such as broken terrain can reduce calibrating gas
Excessively discharge, as shown in connection with fig. 2, in use, box body 2 is covered on SF6Gas leakage warning device detection probe periphery, detection are visited
Matched route is stretched out from gas outlet 1, then by SF6The gas-guide tube 8 of gas leakage warning device tester gas output end
Front end is inserted into air inlet 5, is passed through calibrating gas by air inlet 5, air is gradually discharged, and calibrating gas is filled in collector box
In.Ordinary rubber circle selects top bubble sealing rubber ring.
Further, counterweight 4 is fixedly connected on top surface, counterweight 4 can preferably increase the weight of box body 2, also
So that box body 2 is preferably affixed on the periphery bearing for placing tester detection probe, guarantees the opposing seal of box body 2 and ground.
Preferably, further include handing in hand 3, hand in hand 3 settings on box body 2, lift box body 2 at any time to facilitate.The present embodiment
Additionally provide a kind of preferred counterweight 4 and hand in hand 3 comprehensive design scheme, counterweight 4 is symmetrical with respect to the center line of 2 top surface of box body
Two pieces are fixedly connected with, 3 both ends of handing in hand are separately fixed above two pieces of counterweights 4, in this way, 2 counterweight of entire box body is uniform,
And facilitate lifting.
Preferably, the size and SF of gas outlet 16The route of leakage alarming device tester matches, i.e., with suitable route
Just by being advisable, gas can be discharged in the gap between route, without making gas leak too fast, accelerate calibrating gas filling
Speed.
Preferably, 5 edge wrap of air inlet has a circle rubber sleeve, is provided with through-hole and gas-guide tube inlet end among rubber sleeve
Match, gas can so be prevented to be discharged from inlet end.
SF is carried out using the collector box matching of the present embodiment6The verification of gas leakage warning device, due in SF6Gas is let out
The processing of opposing seal, the SF after 5 ~ 7min, in collector box are made in the periphery of dew warning device detection probe6Gas concentration reaches
To the 95% of standard gas concentration, meet SF6Verification requirement of the gas leakage warning device to gas concentration, to improve inspection
The accuracy of survey, while can also obtain detection repeatability very well.
