Description
Technical field
The present invention relates to direct-current transmission converter valve technical field, more particularly to a kind of direct-current transmission converter valve interformational sliding formula
Access path.
Background technology
Converter valve valve tower is the core component of direct current transportation, is made up of multiple Thyristors in series, and valve tower generally use is by upper
Multiple valve layer for being stacked gradually under, IGCT are uniformly distributed in the structure of each valve layer.With IGCT it is supporting also have radiator,
The devices such as water pipe, driving, damping circuit, reactor, component number is more in converter valve valve tower, needs to consider in the design process
Later stage operation maintenance, the convenience of maintenance.
The maintenance of converter valve valve tower at present mainly has a two ways, one kind be directly operated on lift truck, valve tower
Inside can only overhaul without inspection platform, this mode to valve tower ancillary equipment, if valve tower internal components break down very
Difficulty is safeguarded；Another way is that inspection platform is set inside valve tower, and the structure between inspection platform and valve layer mainly has
Two kinds of forms：The first structure be each valve layer by two half storey being arranged side by side in the horizontal direction valve groups into two half storeys
It is fixed together between valve, inspection platform is set between half storey valve, inspection platform is located at same level with valve layer, due to
All it is directly connected between inspection platform and two half storey valves, to meet insulating requirements, inspection platform must be sufficiently wide, necessarily increases
The floor space of valve tower；Each valve layer is also made up of two half storey valves in another structure, but staggered floor is set between two half storey valves
Put, not on same horizontal plane, inspection platform is arranged on the centre position of two half storey valve vertical direction, the inspection of such a structure
It is smaller and meet insulating requirements to repair berm width, but can only conveniently two half storey valves of maintenance one of them, it is another to be not easy to maintenance
An outer half storey valve.
The content of the invention
Rope technical problems to be solved of the present invention are to be directed to above-mentioned the deficiencies in the prior art, there is provided a kind of direct-current transmission converter
Sliding inspection passage between valve layer, the first device in this direct-current transmission converter valve interformational sliding formula access path easy access valve tower inside
Part, reduce the floor space of converter valve.
In order to solve the above technical problems, the technical scheme that the present invention takes is：Direct-current transmission converter valve interformational sliding formula is examined
Repair passage, including valve layer；It is characterized in that：The valve layer includes the first half valve layer and the second half valve layer；The first half valve layer and
One end of 2 half valve layer is fixedly connected by the first insulator；The other end of the first half valve layer and the second half valve layer is exhausted by second
Edge is fixedly connected；The first half valve layer is connected with the second half valve layer close to one end of the second insulator by metal, shape
Into equipotential；
Also include between the first half valve layer and the second half valve layer and can be along the first half valve layer and the second half valve layer
Adjacent side movement access path.When converter valve is overhauled, the access path 5 slidably needs the position overhauled to valve layer
Postpone fixation.
As further improved technical scheme of the present invention, one side of the access path is arranged on the frame of the first half valve layer
In the right edge of frame, the another side of access path is arranged on the left side of the framework of the second half valve layer；The access path energy
The left side of the framework of the right edge of enough frameworks along the first half valve layer and the second half valve layer slides.It is described when converter valve is overhauled
Fixed behind the position that access path 5 slidably needs to overhaul to valve layer.
As further improved technical scheme of the present invention, access path at least two；Pass through mobile access path energy
Enough make at least two access paths overlapped, the projection of at least two access paths is coincided；Or overhauled by mobile
Passage can deploy at least two access paths, the projection of at least two access paths is not coincided, and form a combination
Access path.When converter valve is overhauled, multiple inspection platforms deploy to form a complete combination maintenance in the length direction of valve layer
Passage.
Invention is provided with inspection platform, easy access valve tower internal component inside valve tower；Access path is arranged in valve
The equipotential end of layer, it is low to the resistance to pressure request of access path, the level interval between two half storey valves is reduced, reduces converter valve
Floor space.The inspection platform that converter valve is laminated when overhauling can deploy to form a complete maintenance in the length direction of valve layer
Passage, multilayer access path is stacked together when converter valve is run.
After such scheme, the invention has the advantages that：
1) inspection platform, easy access valve tower internal component are provided with inside valve tower；
2) access path is arranged in the equipotential end of valve layer, low to the resistance to pressure request of access path, reduces two half storeys
Level interval between valve, reduce the floor space of converter valve.
