Embodiment
The core of the present invention is to provide a kind of anti-error switching device of ultra-high voltage GIS equipment SF6 pipe valves, can effectively prevent extra-high
The problem of mistake of GIS device pipe valve is closed with closing by mistake in buckling power station.
In order that those skilled in the art more fully understands the technical scheme that provides of the present invention, below in conjunction with accompanying drawing and
The present invention is described in further detail for specific embodiment.
It refer to Fig. 1-Fig. 4, a kind of anti-error switching device of ultra-high voltage GIS equipment SF6 pipe valves provided by the present invention, including
The device outer cover 1 and position of the switch warning sign 3 and avoiding improper opening card being set on SF6 pipe valves, can be according to pipe valve shape and chi
Very little design is customized.Particularly, position of the switch warning sign 3 is arranged at the normally opened pipe valve of the SF6 pipe valves, and avoiding improper opening card is set
At the gap of the normally closed pipe valve of SF6 pipe valves.Position of the switch warning sign 3 can use conspicuous color.In the SF6 pipe valves of prior art
Upper attachment means outer cover and position of the switch warning sign, on the premise of being warned in the position of the switch, can ensure pipe valve position in operation
Correctness, effectively prevent SF6 pipe valves in operation in open by mistake or by mistake pass situation generation, can also reduce operation of power networks wind
Danger, greatly improves transformer station's operation maintenance personnel and makes an inspection tour efficiency.
In this programme, the avoiding improper opening card for pinning pipe valve is provided with the gap of the normally closed pipe valve of SF6 pipe valves.It is anti-error
Gap when opening thickness and the pipe valve opening (closing) of card is consistent, avoiding improper opening card is firmly stuck in pipe valve rotating part and this
Between body, when the pipe valve position of the switch changes, avoiding improper opening card drops, and operation maintenance personnel can find that pipe valve position becomes in time when making an inspection tour
Change situation.When SF6 pipe valves are opened by mistake, dropped in avoiding improper opening card slave unit, by observing whether avoiding improper opening card drops, and
Judge whether to be opened by mistake, facilitate walkaround inspection.
Device outer cover 1 is connected with SF6 pipe valves by fastener.Device outer cover 1 is set on the corresponding pipeline of SF6 pipe valves.
This programme also includes being set in the device being connected on the corresponding pipeline of SF6 pipe valves with the openend of device outer cover 1
Base 2.Projection is provided with device outer cover 1 and device pedestal 2, the two is connected by projection, facilitates and inspection is checked and accepted after service work
Look into.Specifically, projection includes multiple first projections for being arranged on device outer cover 1 and be arranged on device pedestal 2 multiple the
Two projections；The fixation threaded hole 5 of multiple first projections at least one be axial and circumferential.Device outer cover 1 passes through device outer cover
With two fixed bolt holes 5 and two fixed bolt holes 5 and device pedestal 2 of horizontal direction of the vertical direction of device pedestal 2
Fixed, forming apparatus base, device outer cover are firmly connected, and are combined closely with SF6 gas pipings, can be in axial and circumferential side
Upward dual fastening.Each pipe valve positional information can be controlled by the lead sealing state and position of the switch warning sign of observing the present apparatus,
Transformer station's operation maintenance personnel can be substantially improved and makes an inspection tour efficiency, it is to avoid by carrying out closing rotation to pipe valve, pipe valve is carried out one by one
Position detection.
Specifically, device pedestal 2 is two hollow plectane compositions, i.e., device pedestal 2 is plectane and plectane center has hollow
It is circular.The internal diameter of the hollow circular of device pedestal 2 is slightly larger than SF6 gas piping external diameters.For device outer cover 1 and device pedestal 2
Internal diameter, should be determined according to actual SF6 gas pipings diameter, to be advisable slightly larger than tubing internal diameter, it is to avoid gap is excessive to cause foreign matter
Into, it is too small cause install inconvenience.Specifically, the connected mode of two hollow plectanes can be, the two edge being connected
It is provided with projection, the relative projection connection of two hollow plectanes.
Device outer cover 1 is set on the corresponding pipeline of SF6 pipe valves.
Device outer cover 1 is connected with SF6 pipe valves or with SF6 gas pipings by fastener, prevents breaker drawing or strong wind
During weather, anti-error switching device is caused to come off.
Device outer cover 1 and/or device pedestal 2 use pmma material, easy for installation, are easy to observation is internal to cut after installation
Door position.
Device outer cover 1 and device pedestal 2 are connected by lead sealing.Lead seal hole 4 is arranged on device outer cover 1 and device pedestal 2
Fixed part, it is ensured that being covered on outside pipe valve can not normally open in the case of not opening lead sealing.
This programme provides a kind of anti-error switching device of ultra-high voltage GIS equipment SF6 pipe valves, meets all kinds of SF6 pipe valves of GIS device
The transparent anti-error switching device of shape and size, is fixed on SF6 gas pipings.The position of the switch is set at normally opened pipe valve gap
Warning sign, warning sign uses conspicuous color, and when pipe valve is closed by mistake, warning sign comes off；Avoiding improper opening is set at normally closed pipe valve gap
Card, pins pipe valve in normally closed position.Install lead sealing additional on anti-error switching device simultaneously, effectively prevent SF6 pipe valves in operation
In the generation for opening by mistake or missing pass situation.
The beneficial effect of this programme is：The correctly open and close of GIS device SF6 pipe valves position are particularly important, once go out
Now open by mistake or close by mistake, will cause during GIS device gas leakage meter can not correctly reflect equipment true pressure, signal can not correctly on
Pass, long-term seepage is likely to result in the serious consequence of GIS device internal flashover, or even causes electric grid large area power cut accident.GIS is set
The research and application of the anti-error switching device of standby SF6 pipe valves, can avoid the generation of above serious consequence from technical measures aspect, by
Possesses the double shield of lead sealing function and position warning sign in the present apparatus, it is ensured that standing the interior GIS device SF6 pipe valves position of the switch just
Really, and influence of the external environment condition to pipe valve is avoided, extension device service life greatly amplitude reduction operation maintenance personnel can also be patrolled in addition
Depending on workload.
Specific case used herein is set forth to the principle and embodiment of the present invention, and above example is said
The bright method and its core concept for being only intended to help to understand the present invention.It should be pointed out that for the ordinary skill of the art
For personnel, under the premise without departing from the principles of the invention, some improvement and modification can also be carried out to the present invention, these improvement
Also fallen into modification in the protection domain of the claims in the present invention.
