Description
Technical field
The utility model belongs to direct current high tension transmission engineering converter power transformer erecting bed protective device technical field.
Background technology
With the development of super high voltage direct current electricity transmission technology, the higher and higher height above sea level of construction addressing of current conversion station, the live change of current
The installation environment of transformer is more and more severe, but core equipment of the converter power transformer as current conversion station, the exchange of its installation quality
The operation of convertor transformer has direct influence.
Required according to Regulations, converter power transformer device body exposes the aerial time (hereinafter referred to as " when device body is cruelly empty
Between ") Fixed Initial Point be to be calculated since being opened seal cover board, when relative air humidity is 65%~80%, the device body cruelly empty time
8h is not greater than, when air humidity is less than 65%, the device body cruelly empty time is not greater than 10h.
It is exactly that the change of current becomes that the converter power transformer fixing link at large-sized converter station exposes aerial process by device body at present
Flow chart in device body, its safeguard procedures are exactly to be blocked temporarily using dust cover to entering hole, and disadvantage is when the progress change of current
When the activity duration increases in transformer body, the device body cruelly empty time is consequently increased, and considerably increases device and experiences tide and dust accumulation
Risk, so as to influence the installation and operation quality of converter power transformer.
The content of the invention
The purpose of this utility model is to solve the deficiencies in the prior art, when carrying out operation in converter power transformer device body, is
Device body adds an isolation strip with external environment condition, there is provided one meets environmental requirement, can ensure that installation quality, raising are safe for operation
Converter power transformer device body in the moisture-proof canopy of operation Special dustproof.
The purpose of this utility model is achieved through the following technical solutions.
For the moisture-proof canopy of operation Special dustproof in converter power transformer device body, including square frame-shaped support frame, it is enclosed in skeleton
The canopy wall of outer integral sealing, offers a single open-door, opposite side offers entrance, is equipped with single open-door in canopy wall side
Upper and lower cat ladder is simultaneously connected by connecting plate with entrance, and the entrance is connected to each other with converter power transformer manhole, entrance side
The part docked with converter power transformer manhole is outer outstanding structure；The support frame uses square steel pipe welded, and canopy wall is using resistance to
Power light-transmitting plate, uses riveting between canopy wall and support frame.
Using flexible bound edge, opposing seal is formed with door body for the doorframe of single open-door and entrance described in the utility model.
When carrying out operation in converter power transformer device body, the utility model is removed to converter power transformer people's hole location, and
It is in close contact with converter power transformer, so that an isolation strip is added between converter power transformer device body and extraneous air, to reduce
Converter power transformer device body exposes aerial time and area, ensures the environmental requirement during operation in device body, prevent dust,
Wet gas enters device body, in switch gate, isolating for transformer body and air is realized using temporary plugging, so as to fulfill whole
Operation process transformer body and ambient atmosphere " zero contacts " in a transformer body, ensure converter power transformer installation and operation
Quality.The utility model uses human oriented design, makes cat ladder up and down, to ensure the safety of operating personnel, improves operating efficiency.
The utility model combination on-site actual situations, a suitable peace is provided for converter power transformer device body inside processing
Environment is filled, reduces the device body cruelly empty time of converter power transformer, prevents transformer from making moist in atmosphere into ash for a long time, influence to change
The insulation performance of convertor transformer, extends the service life of converter power transformer, ensures the running quality of converter power transformer.

Embodiment
Fig. 1, Fig. 2, Fig. 3 are seen, for the moisture-proof canopy of operation Special dustproof in converter power transformer device body, including square frame-shaped support rib
The canopy wall 2 of frame 1, the integral sealing being enclosed in outside skeleton, offers a single open-door 3 in canopy wall side, and opposite side opens up that there is any discrepancy
Mouth 6, upper and lower cat ladder 4 is equipped with single open-door and is connected by connecting plate 5 with entrance 6, the entrance 6 and converter power transformer
Manhole is connected to each other；Using flexible bound edge, opposing seal is formed with door body for the doorframe of single open-door and entrance；Support frame uses
Metal pipe welding structure, canopy wall use transparent material, are connected with support frame by riveting method, and transparent material is change of current transformation
Operation provides sufficient light source in device device body.The utility model entrance and the butted part of converter power transformer manhole are hanged using outer
Structure, so that only butted part is in contact, avoids other parts contact stain.Support frame uses square steel pipe welded, canopy
Wall uses endurance light-transmitting plate, and riveting method is used between support frame, and abundance is provided for operation in converter power transformer device body
Light source.
H represents the height of interior inspection canopy, according to the distance of converter power transformer manhole upper edge to ground and the body of operating personnel
Height determines；H1 represents the distance on terrace at entrance and ground, is determined according to the distance of converter power transformer manhole lower edge to ground；H2
The height of shed special and converter power transformer manhole connector is represented, according to directly determining for converter power transformer manhole；A represents special
The length of canopy lower half, determines according to the distance of terrace at entrance and cat ladder, generally takes 1.5m~2.0m；B represents the width of shed special
Degree, according to directly determining for converter power transformer manhole；C represent converter power transformer manhole to shed special single open-door distance, according to
Converter power transformer manhole and the distance of converter power transformer body edges determine.
In progress converter power transformer device body before operation, the utility model is removed to converter power transformer people's hole location, and
It is in close contact with converter power transformer.During operation, personnel are entered in shed special by single open-door, and closing single open-door is tight, and dismounting is changed
Convertor transformer cover plate for manhole, into device body in work, when need open single open-door when, manhole is blocked with interim diffuser, with
Ensure that device body is not contacted with ambient atmosphere.After the completion of operation, shed special sealing is kept, the installation change of current becomes Manhole Sealing Joints cover board, it
Drop back from shed special.
