Abstract

The utility model relates to a disk spring pressing mechanism for the installation of a thyristor, particularly a critical component thyristor valve of a controllable series compensation device in an electric power system. The outer frame of the mechanism is composed of a left and a right epoxy resin plates 11, a head end flange 10 and a tail end flange 13, wherein a gasket 12 is fixed on the tail end flange 13 through a screw bolt; the mechanism is successively provided with a plurality of groups of water cooling radiators 2 and flat plate thyristors 1, which are connected in series at intervals, and a butting and pressing transition plate 5; the external side of the butting and pressing transition plate 5 is provided with a butting and pressing component which is composed of a plain cushion 9, a plurality of disk springs 8, a guide sleeve 6 and a butting and pressing screw bolt 7. The disk springs 8 of the butting and pressing component can generate sufficient axial pressure to tightly press the groups of the flat plate thyristors 1 and the water cooling radiators 2 through screwing the butting and pressing screw bolt 7, which reduces the thermal contact resistance and the contact resistance between the flat plate thyristors 1 and the water cooling radiators 2, thereby, the installation requirement of the thyristors is satisfied so as to achieve favorable heat radiation effect.

Description

The disc spring pressing mechanism that thyristor is installed
Technical field
The utility model relates to the critical component thyristor valve of controllable series compensator in the electric power system, particularly the disc spring pressing mechanism of installing about thyristor.
Background technology
Thyristor valve is the core part of controllable series compensator in the electric power system.Thyristor owing to oneself power consumption produces a large amount of heats, does not distribute these heats if do not take appropriate measures when work, will cause that the module tube core PN junction temperature of thyristor 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, after having selected suitable radiator, the installation constitution of radiator also is vital.Have only the rational radiator installation constitution of employing, could guarantee that the thermal resistance between radiator and thyristor chip meets the demands.At present high-power thyristor is generally flat, and its radiator structure is normally at two plane upper press cover radiators of thyristor and distribute heat.The embodiment that is adopted in the middle of the prior art that is shown in Figure 1: adopt 3 or 4 stay bolts of circumference uniform distribution to transmit axial force, compress the gland at two ends; Gland compresses flat thyristor and radiator by cross-over block, dish spring, plain washer etc. again.This mounting structure complex forms, assembly and disassembly are all cumbersome.During manual the installation, adopt torque wrench, to the clamp nut of all bolts alternately evenly firmly, otherwise easily make the interface pressure inequality of flat thyristor and radiator, cause loose contact and influence radiating effect.
Summary of the invention
In order to overcome the thyristor valve mounting structure complex forms of prior art, the defective of assembly and disassembly trouble, it is simple that the purpose of this utility model provides a kind of mounting structure, easy accessibility, and the two sides of flat thyristor contacts good thyristor valve mounting structure with radiator.
The technical scheme in the invention for solving the technical problem is: the disc spring pressing mechanism of installing about thyristor by about two dielectric panels 11 and head end flange 10, tail end flange 13 constitute the housing of this structure.Pad 12 is fixing by bolt and tail end flange 13.Many groups water-filled radiator 2 and the flat thyristor 1 and the roof pressure rebound 5 of alternate serial connection are installed successively from tail end to head end, and roof pressure rebound 5 outsides are equipped with the roof pressure assembly.The roof pressure assembly is made up of plain cushion 9, multi-disc dish spring 8, guide pin bushing 6 and roof pressure bolt 7.By screwing roof pressure bolt 7, can make dish spring 8 in the roof pressure assembly produce that enough axial compressive forces will be organized flat thyristor 1 more and water-filled radiator 2 compresses, reduce contact heat resistance and contact resistance between flat thyristor 1 and the water-filled radiator 2, thereby satisfy the installation requirement of thyristor, reach better heat radiating effect.
Owing to adopted above-mentioned technical scheme, the beneficial effect that the utlity model has is: 1, epoxy resin board is applied in the two ends of whole thyristor valve mounting structure, and insulation measures is simple and easy to do and reliable; 2,1 roof pressure bolt of operation can be realized the dismounting of whole thyristor valve mounting structure, convenient maintenance and replacement; 3, can directly apply pressure by 1 roof pressure bolt, can not press partially, press askew, and damage device from the center to whole thyristor valve mounting structure; 4, only need to control the deflection of disk spring in the thyristor valve mounting structure, regulate thrust required between flat thyristor and the radiator easily by regulating 1 roof pressure bolt.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is the schematic diagram of the mounting structure of central thyristor of prior art and radiator;
Fig. 2 is the schematic diagram that the utlity model has the thyristor valve mounting structure of disc spring pressing mechanism.
Embodiment
Referring to Fig. 2, the thyristor valve mounting structure that expression the utility model is taked with disc spring pressing mechanism.By about two load epoxy resin boards 11 and head end flange 10, tail end flange 13 be assembled into the structure housing that thyristor is installed.Earlier that aluminium pad 12 is fixing by bolt and tail end flange 13; From tail end pack into successively many groups water-filled radiator 2 and the flat thyristor 1 and the roof pressure rebound 5 of alternate serial connection, the roof pressure assembly is installed then again.The roof pressure assembly by plain cushion 9, organize dish spring 8, guide pin bushing 6 and roof pressure bolt 7 more and form.Screw roof pressure bolt 7 at last, make dish spring 8 produce that enough axial compressive forces will be organized flat thyristor 1 more and water-filled radiator 2 compresses, reduce contact heat resistance and contact resistance between flat thyristor 1 and the water-filled radiator 2, thereby satisfy the installation requirement of thyristor, reach better heat radiating effect.
