Description
Technical field
The utility model relates to direct-current transmission converter valve technical field, particularly relates to a kind of direct-current transmission converter valve interformational sliding formula access path.
Background technology
Converter valve tower is the core component of direct current transportation, is made up of multiple Thyristors in series, and valve tower adopts multiple valve layer, the thyristor stacked gradually to be uniformly distributed in the structure of each valve layer usually from top to bottom.With thyristor supporting also have the device such as radiator, water pipe, driving, damping circuit, reactor, in converter valve tower, component number is many, needs the convenience considering later stage operation maintenance, maintenance in the design process.
The maintenance of current converter valve tower mainly contains two kinds of modes, and one is directly inner without inspection platform at the enterprising line operate of lift truck, valve tower, and this mode can only be overhauled valve tower ancillary equipment, if valve tower internal components breaks down, is difficult to safeguard; Another kind of mode arranges inspection platform in valve tower inside, structure between inspection platform and valve layer mainly contains two kinds of forms: the first structure is that each valve layer is made up of the half storey valve that two are arranged side by side in the horizontal direction, be fixed together between two half storey valves, between half storey valve, inspection platform is set, inspection platform and valve layer are positioned at same level, owing to being all directly connected between inspection platform with two half storey valves, for meeting insulating requirements, inspection platform is sufficiently wide, necessarily increases the floor space of valve tower; In another kind of structure, each valve layer is also made up of two half storey valves, but staggered floor is arranged, not on same horizontal plane between two half storey valves, inspection platform is arranged on the centre position of two half storey valve vertical direction, the inspection platform width of this kind of structure is less and meet insulating requirements, but one of them of maintenance two half storey valves can only be facilitated, be not easy to maintenance another one half storey valve.
Utility model content
The technical problem that the utility model asks for solution is for above-mentioned the deficiencies in the prior art, a kind of direct-current transmission converter valve interformational sliding formula access path is provided, this direct-current transmission converter valve interformational sliding formula access path easy access valve tower internal component, reduces the floor space of converter valve.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is: direct-current transmission converter valve interformational sliding formula access path, comprises valve layer; It is characterized in that: described valve layer comprises the first half valve layer and the second half valve layer; The first half valve layer are fixedly connected with by the first insulator with one end of the second half valve layer; The first half valve layer are fixedly connected with by the second insulator with the other end of the second half valve layer; Described the first half valve layer are connected by metal with one end near the second insulator of the second half valve layer, form equipotential;
Also to comprise between the first half valve layer and the second half valve layer and can along the access path of the adjacent side movement of the first half valve layer and the second half valve layer.During converter valve maintenance, described access path 5 is fixing slidably need the position of maintenance to valve layer after.
As the technical scheme that the utility model improves further, in the right edge being arranged on the framework of the first half valve layer of described access path, the another side of access path is arranged on the limit, left side of the framework of the second half valve layer; Described access path can slide along the limit, left side of the framework of the right edge of the framework of the first half valve layer and the second half valve layer.During converter valve maintenance, described access path 5 is fixing slidably need the position of maintenance to valve layer after.
As the technical scheme that the utility model improves further, access path is at least two; At least two access paths can be made overlapped by mobile access path, the projection of at least two access paths is coincided; Or at least two access paths can be made to launch by mobile access path, the projection of at least two access paths not coincided, forms a combination access path.During converter valve maintenance, multiple inspection platform launches the complete combination access path of formation one at the length direction of valve layer.
Utility model is provided with inspection platform in valve tower inside, easy access valve tower internal component; Access path is arranged in the equipotential end of valve layer, low to the requirement of withstand voltage of access path, reduces the level interval between two half storey valves, reduces the floor space of converter valve.Inspection platform stacked during converter valve maintenance can launch the complete access path of formation one at the length direction of valve layer, and when converter valve is run, multilayer access path is stacked together.
After adopting such scheme, the utility model has following beneficial effect:
1) inspection platform is provided with in valve tower inside, easy access valve tower internal component;
2) access path is arranged in the equipotential end of valve layer, low to the requirement of withstand voltage of access path, reduces the level interval between two half storey valves, reduces the floor space of converter valve.
