Description
Technical field
The utility model relates to SF
6sF is carried out under relating to equipment live state in gas detection technology field, particularly one
6the coupling arrangement that gas sample detects.
Background technology
SF
6gas is because having excellent insulation and arc extinction performance, and the utilization in sleeve pipe, mutual inductor, isolating switch is more and more extensive.From being filled with SF
6sample and carry out the important technology that gaseous mass analysis has become equipment fault diagnosis at present in the equipment of gas, to latent fault in Timeliness coverage equipment, ensureing that power network safety operation is significant.
At present, existing research shows, the factor such as sorbent suspension, temperature variation affects, the SF gathered in the energized state
6gas sample can more gaseous mass situation in actual response equipment, therefore needs to carry out SF in the energized state
6gas sampling and analysis.
Utilize existing SF
6gas sampling joint connect charged Devices to test carry out live detection or sampling time, there is the risk point of following several respects:
1, the air hatch of common isolating switch, sleeve pipe, GIS device is set to spring reverse checkvalve usually, when getting gas, needs to be backed down with getting gas joint thimble, and when taking off gas joint, by the air hatch of spring reverse checkvalve resilience closing device.Once there be minute solid particles to drop in the stroke range of spring reverse checkvalve, then easily cause spring reverse checkvalve jam, as do not recovered, equipment will be caused to continue gas leakage, and then cause device action.
2, traditionally gas joint pipeline connected mode is got, the gas piping connected and sampling jar carry out equipment when vacuumizing, if equipment end switch seal is tight in gas piping, then easy gas in equipment to be vacuumized, cause pressure in equipment to decline rapidly, cause device action.
3, the sampling jar vacuumized and gas piping be communicated with equipment moment easily cause instantaneous velocity too fast, cause SF
6in density monitor, the beat of pointer is excessive, causes device action.
Visible, existing this connected mode lacks effective protection mechanism, carries out SF in the energized state
6exist during gas detect and by mistake send out the kinds of risks such as alarm signal, leakage, and with inconvenient operation during equipment connection Screw joint, cause pipeline to be wound around.Be necessary SF
6the coupling arrangement that gas sample detects improves.
Summary of the invention
For the problems referred to above, under the utility model proposes a kind of electriferous state, carry out SF
6the coupling arrangement of gas detect, to reduce equipment to be detected and coupling arrangement to send out alarm signal and leakage risk in the mistake connected with cause during sampling.
In order to solve the problems of the technologies described above, the technical solution of the utility model is as follows:
One carries out SF
6the coupling arrangement that gas sample detects, what comprise the air hatch being connected to Devices to test gets gas joint, also comprise X-over, Pneumatic quick connector, one end of described X-over is set in the outlet of getting gas joint, and the other end is connected to getting in feed channel of external detection instrument via described Pneumatic quick connector.
Above-mentioned coupling arrangement, successively by getting gas joint, X-over, Pneumatic quick connector are connected to external detection instrument gets in feed channel, avoid the lasting leakage problem that spring reverse checkvalve bite causes, and the node added between Devices to test to detecting instrument, can simultaneously in multiple Node configuration containment measures, effectively prevent Devices to test air pressure from declining, and can cushion air-flow in sampling testing process, reduce flow perturbation; By Pneumatic quick connector, X-over and checkout equipment are coupled together, operate more convenient, overcome tradition get gas joint directly and checkout equipment get the pipeline that feed channel threaded engagement causes and be wound around problem, be convenient to on-site sampling.
The built-in pipeline of described X-over is that caliber is less than the current limiting tube getting the outlet of gas joint, and is provided with current limliting valve on this current limiting tube.Energy is buffer gas flow further, prevents connecting instant airflow excessive, and can utilize current limliting valve closing current limiting tube, plays the effect disconnecting pipeline and connect.
The utility model has the advantages that: simple and reasonable for structure, can SF be reduced
6leakage Gas potential during gas detect sampling, equipment malfunction make equivalent risk, carrying out limiting and cushioning, reducing air-flow to density monitor disturbance to getting air-flow in air pipe.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Description of reference numerals: 1, get gas joint; 2, X-over; 3, current limliting valve; 4, current limiting tube; 5, Pneumatic quick connector; 6, feed channel is got.
Embodiment
For enabling above-mentioned purpose of the present utility model, feature and advantage become apparent more, are described in further detail the utility model below in conjunction with the drawings and specific embodiments.
Embodiment
As shown in Figure 1, one carries out SF
6the coupling arrangement that gas sample detects, what comprise the air hatch being connected to Devices to test gets gas joint 1, also comprise X-over 2, Pneumatic quick connector 5, one end of described X-over 2 is set in the outlet of getting gas joint 1, and the other end is connected to getting in feed channel 6 of external detection instrument via described Pneumatic quick connector 5.
Further, in described X-over 2, caliber is less than connection and gets air pipe 6 (being generally 1/4 inch pipe), and is provided with current limliting valve 3 on current limiting tube 4.
Pneumatic quick connector 5 is that one is mainly used in air line, air tool rapid-acting coupling, do not need instrument just can realize the joint of pipeline connection or disconnection, it adopts two ends retractable roof structure, namely after pulling out, two ends are closed, and plugged and just made two ends conducting, being specifically arranged on prior art has a lot, those skilled in the art can optionally select, and this is not restricted.
Above-mentioned coupling arrangement, successively by getting gas joint 1, X-over 2, Pneumatic quick connector 5 are connected to external detection instrument gets in feed channel 6, avoid the lasting leakage problem that spring reverse checkvalve bite causes, and the node added between Devices to test to detecting instrument, can simultaneously in multiple Node configuration containment measures, effectively prevent Devices to test air pressure from declining, and can cushion air-flow in sampling testing process, reduce flow perturbation; By Pneumatic quick connector 5, X-over 2 and checkout equipment are coupled together, operate more convenient, overcome tradition get gas joint 1 directly and checkout equipment get the pipeline that feed channel 6 threaded engagement causes and be wound around problem, be convenient to on-site sampling.
Routine gets gas joint 1 pipeline after evacuation and equipment moment connected by sampler, easily causes SF
6in density monitor, pressure drop is too fast, causes equipment to send out alarm signal by mistake.And the utility model is at the adapter coupling getting gas joint 1 back extension flow restriction, can effective buffer gas flow, prevent gas flow rate in sampling process excessive, avoid equipment malfunction and do.
Pneumatic quick connector 5 is expanded at adapter coupling rear portion again, be connected with the sampling pipe of detecting instrument by Pneumatic quick connector 5, when this Pneumatic quick connector 5 is extracted, Pneumatic quick connector 5 both sides are all closed, formation gas passage, Pneumatic quick connector 5 both sides during connection, following effect can be played:
