Description
Technical field
The present invention relates to the mounting structure of the core apparatus thyristor valve of Static Var Compensator in electric power system and the power electronic technology (SVC), particularly a kind of Prossure fixing mechanism of series thyristor valve group.
Background technology
Thyristor valve is the core part of Static Var Compensator.The thyristor valve group must guarantee that it has the favorable mechanical stability when work.Thyristor owing to oneself power consumption generates heat, does not distribute this heat if do not take appropriate measures when work in addition, will cause that module tube core PN junction temperature sharply rises, and causes device property to worsen, until damaging fully.
For make thyristor bring into play its rated performance fully and improve to use in reliability, except that must scientifically selecting also to need the radiator correctly to install.Have only and radiator correctly is installed is guaranteed that the thermal resistance between itself and thyristor chip meets the demands.When element and radiator assembling, should note: the table top of radiator must be complementary with the element mesa dimensions, prevents that pressure is inclined to one side, it is askew to press, and damages device; Want the holding element table top parallel fully, concentric with the table top of radiator; In the installation process, require to exert pressure, so that pressure is evenly distributed on whole contact area by the element center line; The size of pressure will reach requirement in the tables of data.
Prior art adopts 3 or 4 stay bolts of circumference uniform distribution to come transmitter shaft to the gland of defeating tight two ends mostly, and gland compresses thyristor and radiator by cross-over block, dish spring, plain washer etc. again.This version complexity mounts and dismounts all cumbersomely, easily makes the pressure inequality of thyristor and radiator contact-making surface.
Summary of the invention
In order to overcome the above-mentioned defective in the middle of the prior art, the purpose of this invention is to provide a kind of hold-down mechanism of installing about thyristor.The present invention can guarantee to reach above-mentioned required technological requirement when thyristor is installed, and simple to operate, easy for assembly, disassembly and maintenance.
The present invention solves the technical scheme that its technical problem takes:
A kind of Prossure fixing mechanism of series thyristor valve group is assembled into housing by 3 load epoxy plates 3 and head end flange 4, tail end flange 5;
In head end flange 4 one sides, be with dish spring 7 on the stage clip guide rod 6; First end-side at dish spring 7 is equipped with dish spring screening glass 8; Opposite side at dish spring 7 is equipped with water conservancy diversion copper bar 9 and transition adjustment circle aluminium 10 successively;
In tail end flange 5 one sides, fairlead 12 is connected with tail end flange 5; Along from first end-side side direction caudad, be with transition adjustment circle aluminium 10, tail end water conservancy diversion copper bar 9 and roof pressure guide rod 11 on the fairlead 12 successively; Tail end flange 5 outermost are installed hex bolts 13;
Between two transition adjustment circles of head and the tail aluminium 10, alternate many group water-filled radiators 2 and the thyristor 1 of being serially connected with.
By screwing top hexagon socket head cap screw 13, can make dish spring 7 produce enough axial compressive forces thyristor 1 and water-filled radiator 2 are compressed, reduce contact heat resistance and contact resistance, thereby satisfy the installation requirement of thyristor.
Owing to adopted above-mentioned technical scheme, the beneficial effect that the present invention has is:
Epoxy plate runs through two ends, and insulation measures is simple and easy to do and reliable; Only depend on 1 hexagon socket head cap screw 13 of degree of tightness can realize the dismounting of thyristor, convenient maintenance and replacement; Directly apply pressure during installation, can not press partially, press askew, and damage device from the center; Can control the deflection of disk spring by regulating hexagon socket head cap screw 13, the required thrust scope of thyristor is real easily; Fairlead 12 guarantees that the thyristor valve group can offset direction, and therefore, the present invention can guarantee that the thyristor valve group is stressed evenly, mechanical stability is good.
