Description
Technical field
The utility model relates to high-power electric and electronic rectification and inverter, particularly a kind of thyristor converter valve module for high voltage direct current transmission, DC ice melting equipment, SVC etc.
Background technology
The thyristor converter valve module is as the core component of HVDC (High Voltage Direct Current) transmission system, and its development and application have had history for many years.
The thyristor converter valve module mainly contains two kinds of versions at present, and a kind of is the big frame formula, and another is the little module formula.Big frame formula valve module is assembled together thyristor level control loop and water cooling reactor, mainly there is following drawback in it: first, big frame formula thyristor converter valve module adopts the fixed form of frame aluminium section bar and supporting insulator, its overall dimensions is larger, and assembling, transhipment, test and transportation be difficulty relatively; The second, big frame formula thyristor valve assembly adopts small-bore water route design in parallel, and design difficulty is larger, and waterway connector is many, leaks and has a big risk, and water route is easily stopped up; The 3rd, all down and be positioned at bottom, the upper strata valve module leaks and is easy to cause lower floor's valve module electric component accident that is short-circuited all waterway connectors of big frame formula thyristor converter valve module.Little module formula thyristor valve assembly is not containing water cooling reactor, and mainly there is following drawback in it: the first, and during test, need extras that valve module and water cooling reactor are linked together, more loaded down with trivial details; The second, although little module formula thyristor valve assembly is compact small and exquisite, quantity is a lot, and on-the-spot valve tower installation workload is very large; The 3rd, the on-the-spot minute branching pipe of connection that needs is more, and the water pipe head of joint connection in site is more, and the probability that leaks is relatively large.
The Chinese patent that notification number is CN201937444U discloses a kind of thyristor converter valve module, this valve module comprises framework, valve section and water-cooling system, the valve section comprises the thyristor unit that several Thyristors in series form, water-cooling system is comprised of one group of water-filled radiator and water pipe, each thyristor both sides correspondence of thyristor unit is connected with a water-filled radiator, integral water-cooled system is divided at least two separate units that are connected in parallel, each unit is provided with independently water inlet and delivery port, and the water inlet in each unit and delivery port are on different water-filled radiators.Be connected with the water route of connecting of all water-filled radiators of serial connection between water inlet and delivery port.In this module, owing to having adopted the design of connection in series-parallel water route, at first water route node and pipeline have been reduced, and optimized radiating effect, thereby can more thyristor be installed on a valve module, in addition, this module has all concentrated on the electric elements such as valve section, thyristor control unit, damping capacitor unit and water-cooling system on a framework, connect the shortest, the various electromagnetic interference of wire between each electric unit and dropped to minimum, therefore can assemble on less station.Adding can be by the reactor fast integration of above-mentioned valve module and converter valve components to form the thyristor converter valve module, the converter valve components of integrated rear formation certainly will be able to possess the advantage of existing big frame formula thyristor converter valve module and small frame formula thyristor converter valve module simultaneously, both be convenient to transportation, be convenient to again assembled in situ.
Summary of the invention
The purpose of this utility model is to provide a kind of transportation of both being convenient to, and is convenient to again site-assembled thyristor converter valve module.
In order to address the above problem, the thyristor converter valve module is by the following technical solutions: the thyristor converter valve module, comprise valve module and corresponding reactor with it, described valve module comprises framework, on the frame-type base that fixedly is assemblied in a rectangle that described valve module and reactor are removable and along the left and right directions of base, distribute, described base comprises front bezel, rear frame, left frame, left frame and bridge joint are front, brace summer between rear frame, left, before the length of left frame is less than, the length of rear frame, and left, left frame consists of aluminium section bar, before, one in rear frame consists of aluminium section bar, another is made by insulating material.
Described valve module and reactor respectively have two, and two reactors are positioned at the place, two ends, left and right of base, and valve module is between two reactors.
Described brace summer is made by the flame-resistant insulation material.
Be provided with diagonal brace between adjacent two frames of base.
Described valve module comprises thyristor control unit and water-filled radiator, and thyristor control unit is encapsulated in the aluminium box and is fixed on corresponding water-filled radiator.
In this thyristor converter valve module, because valve module has framework, itself be the parts that possess high integration, possesses the advantage that volume is little, in addition, valve module and reactor are all removable fixedly being assemblied on base, in the time of transportation, only need that valve module and corresponding reactor are unloaded to independent transportation and get final product, thereby can realize the convenient transportation to the thyristor converter valve module, simultaneously, when assembling this converter valve components itself, only need the corresponding position that valve module and reactor are separately fixed on base to get final product, when this converter valve components is applied to the valve tower, a left side due to base, left frame is aluminium section bar, before, one in afterframe is aluminium section bar, base itself just can play the effect of high-tension shielding, do not need to arrange specially more corresponding shielding construction, thereby also simplified the assembling process to the valve tower, in the process of using in reality, in order to meet the needs of power, can also be connected and arrange side by side in these converter valve components front and back of two covers at the same layer of valve tower, this also reduces to provide condition for the converter valve components volume to a certain extent.In sum, this thyristor converter valve module possesses simultaneously and is convenient to transportation and is convenient to site-assembled advantage.
Further, two valve modules and being symmetrical arranged of reactor can be provided convenience for arranging of cooling water pipe, simplify the design of cooling water pipe; Diagonal brace plays the effect of strengthening base; The thyristor control unit individual packages is fixed on to water-filled radiator in the aluminium box, not only make control unit minimum to the distance of thyristor gate leve, and the aluminium box not only has electro-magnetic screen function, and there is protection against the tide, waterproof, protection against the tide, the functions such as heat radiation, extended useful life of thyristor control unit greatly.
