6gas apparatus, tensimeter, detecting instrument and exhaust apparatus, be provided with reverse checkvalve between described detecting instrument and interface.The utility model is easy to install, and versatility is good, also can reduce SF simultaneously
6gas live detection leak rate, improves detect security, ensures the safety of electrical network and testing staff.
Description
Technical field
The utility model relates to SF
6gas-detecting device.
Background technology
According to charged electric power apparatus inspection specifications, to GIS device and open type SF
6breaker apparatus requires to put into operation latter 1 year, within later every 3 years, detects a SF
6gas humidity Sum decomposition thing.
Existing SF
6in gas-detecting device, the detection tabs of detecting instrument is directly connected on equipment interface, testing process is generally first detecting instrument is connected, open detecting instrument power supply, by switch contacts, reverse checkvalve is backed down, so just can detect SF6 gas, directly switch contacts be removed just to complete from equipment after completing and have detected.
Now use SF
6gas switch piecing devices, have the following disadvantages: SF
6gas switch piecing devices itself are heavier, equipment interface will be made to bear pressure, likely the pipe of interface is bent; Hypotelorism between secondary valve and tensimeter, and switch contacts device is installed and cannot be used spanner, and install inconvenient, joint quantity is few, and switch contacts cannot be general, causes this device to be applied to a few devices.
Utility model content
Technical problem to be solved in the utility model is just to provide a kind of SF
6gas-detecting device, easy to install, versatility is good.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of SF
6gas-detecting device, comprises a four-way valve, and four interfaces of four-way valve connect SF successively
6gas apparatus, tensimeter, detecting instrument and exhaust apparatus, be provided with reverse checkvalve between described detecting instrument and interface.
Preferably, described exhaust apparatus comprises gas outlet and is located at the vent valve on gas outlet.
Preferably, described gas outlet end connects gas-holder.
The utility model is for existing SF
6gas-detecting device, joint is overweight, and joint quantity is few, installs inconvenient problem, utilizes existing SF
6gas detecting instrument, when not changing two end connectors, at detecting instrument and SF
6install a four-way valve between gas apparatus additional, connect SF
6gas apparatus, tensimeter, exhaust apparatus and detecting instrument, easy to install like this, versatility is good, also can reduce SF simultaneously
6gas live detection leak rate, improves detect security, ensures the safety of electrical network and testing staff.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further described:;
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, SF
6gas-detecting device, comprises a four-way valve 1, and four interfaces of four-way valve connect SF successively
6gas apparatus 2, tensimeter 3, detecting instrument 4 and exhaust apparatus 5, be provided with reverse checkvalve 6 between described detecting instrument and interface.
Described exhaust apparatus 5 comprises gas outlet and is located at the vent valve on gas outlet.Described gas outlet end connects gas-holder.Open vent valve after detection completes, utilize gas-holder to store residual gas simultaneously, improve security, also improve the accuracy of subsequent detection.
Above-mentioned SF
6after gas-detecting device completes, in real work, the many-sides such as its on-the-spot applicability, ease-to-operate, fixed property and safe reliability are tested.
1, on-the-spot applicability:
In application process, application be original instrument producer configuration joint, these joints can be applied to various different switch, meet the requirement of on-the-spot applicability.
2, ease-to-operate:
Each SF
6during gas detect, as long as find corresponding instrument joint, just can detect, simple and convenient.
3, safe reliability:
By using this SF
6gas-detecting device and change detecting step, can avoid SF completely
6the generation of gas jet fault, detects end at every turn, after all the gas inside pipeline being discharged by vent valve, then instrument joint is removed from equipment, such SF
6gas would not be sprayed onto on the person, ensures testing staff's safety.
Use SF of the prior art
6gas-detecting device, the process that switch contacts is directly removed from equipment, cannot judge reverse checkvalve whether normally closed, if reverse checkvalve cannot normally closed, will spray a large amount of SF
6gas, device interior SF
6gas density declines, and switchgear and GIS device insulation is declined, likely causes insulation breakdown, finally cause large-area power-cuts and environmental pollution accident.
For above-mentioned situation, adopt SF of the present utility model
6gas-detecting device, can by changing detecting step, and avoid the generation of jet accident, step is as follows:
1, after detection completes, the joint spanner of instrument is outwarded winding to can manual rotation, and reverse checkvalve resets under normal circumstances;
2, open the vent valve in exhaust system, confirm that residual gas drains by manometric instruction change, at this moment tensimeter is designated as zero, closes the valve of vent valve and instrument;
3, at this moment observing manometric instruction has unchanged, if manometric instruction is non-vanishing, illustrates that reverse checkvalve is not closed completely, then by spanner, joint can be screwed, by check valve core moving back and forth once, repeat step above, until reverse checkvalve normally closed.If tensimeter is designated as zero, then can directly many for instrument joint SF
6gas apparatus directly removes, and test terminates.
By above-mentioned steps, when directly instrument joint being removed from device junction after detection can be avoided to complete, due to the mechanical fault of check valve core, cause SF
6leakage Gas, thus cause jet fault.
