Abstract
The present invention relates to a high-power electrical electronic rectification and inversion apparatus, and specifically relates to a valve tower for thyristor converter valves, applicable in the fields of high-power high-voltage power transmission engineering and high-power direct-current ice melting. The valve tower comprises two or more valve layers which are laminated from top to bottom. Each valve layer includes at least two converter valve assemblies arranged side by side, and adjacent two converter valve assemblies in the same valve layer are arranged with an interval therebetween and fixedly connected together. A maintenance area is formed in the interval between adjacent two converter valve assemblies in the same valve layer, and a maintenance channel for maintenance personnel to get in and out is formed by the maintenance areas in different valve layers in up-down correspondence. According to the invention, the valve tower has the maintenance channel which provides a space for the operation of the maintenance personnel, such that the operation of the maintenance personnel is convenient, and the problem of the inconvenience in the maintenance caused by the small maintenance space of the conventional valve tower for the converter valves is solved.
Description
Technical field
The present invention relates to high-power electric and electronic rectification and inverter, particularly a kind of thyristor converter valve tower that can be applied in high-power high voltage power transmission engineering field and high power DC ice-melt field.
Background technology
As one of core component in high-power high voltage power transmission engineering and high power DC ice-melt field, thyristor converter valve tower has been waited until and has been applied more and more widely.Common thyristor converter valve tower is connected in series successively by several thyristor converter valve module (hereinafter referred to as valve module) to form.The layout type of traditional converter valve tower is that several valve module is cascading from the top down, and each valve module forms a valve layer, in order to ensure space length and creepage distance, is be mechanically connected by suspension insulator mostly between two adjacent valve modules.In addition, be connected in series by aluminium row between adjacent valve module, wherein aluminium ranking is in the middle of two valve modules of correspondence, in order to ensure the normal working temperature of valve module, each valve module has respective cooling structure, between adjacent two valve modules cooling structure connected by pipe with spiral pipe.
As the classical arrangement form of converter valve tower, above-mentioned converter valve tower in very large range obtains application, but due to the limited separation between adjacent valve module, this causes being greatly limited the service clearance of valve module, once there is the situation that valve module components and parts are damaged, the maintenance work of maintenance personal just can seem extremely difficult; In addition, the aluminium ranking of connection valve assembly is between valve module, and the alternating current-direct current of valve tower occurs it being very trouble, connects loaded down with trivial details; Moreover in order to ensure cooling effect, be provided with water pipe between the valve module in conventional valve tower, this makes service clearance natively hard up between valve module seem more crowded, further inconvenience is brought to the maintenance of valve module; Finally, the water pipe of connection valve assembly is unavoidable in running there will be drainage, once the water pipe being positioned at the valve module of top leaks, the water then spilt can directly splash on the electric elements of below valve module, thus considerably increases the risk that major accident occurs due to valve module short circuit.
Summary of the invention
The object of the present invention is to provide a kind of thyristor converter valve tower, to solve the problem of the inconvenient maintenance that current converter valve tower produces because service clearance is little.
In order to solve the problem, thyristor converter valve tower of the present invention is by the following technical solutions: thyristor converter valve tower, comprise the valve layer of two or more stacked setting from top to bottom, each valve layer comprises at least two converter valve components be arranged side by side, adjacent two converter valve components intervals in same valve layer arrange and are fixed together, gap-forming maintenance area between adjacent two converter valve components of each valve layer, the upper and lower correspondence in maintenance area in each valve layer also together form the maintenance channel passed in and out for maintenance personal, the converter valve components of same valve layer is cascaded.
Be provided with at least one deck maintenance platform in described maintenance channel, maintenance platform and adjacent converter valve components are fixed together.
At least one end place of described maintenance channel is provided with insulating ladder.
Connected by aluminium row between the converter valve components of same valve layer, aluminium ranking is in described maintenance channel.
Also comprise cooling line, described cooling line is arranged around described valve tower from top to bottom.
Each valve layer due to this thyristor converter valve tower comprises at least two converter valve components be arranged side by side, adjacent two converter valve components intervals in same valve layer arrange and are fixed together, and the gap-forming maintenance area between adjacent two converter valve components of each valve layer, the upper and lower correspondence in maintenance area in each valve layer also together form the maintenance channel passed in and out for maintenance personal, arranging of described maintenance channel can provide the space of maintenance operation for maintenance personal, thus provide convenience for the maintenance work of maintenance personal, solve the problem of the inconvenient maintenance that current converter valve tower produces because service clearance is little.
Further, arranging of maintenance platform is on the one hand diverse location in order to enable maintenance personal in maintenance channel, differing heights place carries out maintenance work, further for maintenance work is provided convenience, be also to reinforce two converter valve components adjacent in same valve layer on the other hand; Insulating ladder plays the effect of reinforcing converter valve components on the one hand, can coordinate the level as far as possible expanding maintenance personal, vertical scope of activities on the other hand with described maintenance platform; Aluminium row being located in maintenance channel is space in order to discharge between two neighbouring converter valve components, for the maintenance operation of maintenance personal is provided convenience, after cooling line is arranged around valve tower, release the space between upper and lower two adjacent converter valve components on the one hand further, for maintenance is provided convenience, pipeline also can be avoided to leak on the other hand and cause the components and parts short circuit of converter valve components.
In sum, the present invention is ensureing, under the prerequisite that valve tower structure is compact, to increase the service clearance of maintenance personal to greatest extent, thus make the maintenance work of converter valve components not only convenient and swift, and fool proof.
Accompanying drawing explanation
Fig. 1 is the structural representation of thyristor converter valve tower.
