Description
Technical field
The present invention relates to the spring suspension mechanism of the servicing unit of controllable series compensator in electric power system and the power electronic equipment, particularly a kind of thyristor valve.
Background technology
Thyristor valve is the core part of controllable series compensator in the electric power system.And used thyristor valve will bear high voltage and big electric current in the controllable series compensator, needs to adopt a plurality of high-power thyristor connection in series-parallel to realize.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 and adopt rational radiator installation constitution, could not only guarantee the requirement of dispelling the heat but also be convenient to install and the operation of maintenance process.At present, high-power thyristor all is a plate armature, and its profile is the metal sealing shell as shown in Figure 1, disc type encapsulation, the mode of the two-sided cooling of employing ceramic insulation.The profile of used radiator as shown in Figure 2, top is the main circuit contact, the bottom is the gateway, water route.The thyristor of this structure and radiator do not have suitable hitch and hang mounting points, only depend on axial pressing force will organize thyristor and water-filled radiator compresses and fixes more.This structure is in the maintain and replace process, need to put into the bottom of thyristor valve string, hold the bottom of all thyristors and radiator and drag, but also need avoid the element and the circuit of thyristor valve string bottom to prevent it with suitable frock, the operating procedure more complicated, consuming time taking a lot of work.Especially cumbersome when the connection in series-parallel of carrying out a plurality of thyristors is installed.
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 simple in structurely, install and the maintain and replace technology mounting structure of thyristor valve easily.
The present invention solves the technical scheme that its technical problem takes: a kind of spring suspension mechanism of installing about thyristor valve, by hook on bolt 1, hang spring 2, mast-up 3 constitutes.Hook on bolt 1 is tightened on the dielectric panel 4, and thyristor 5 and radiator 6 are plugged on the mast-up 3, and mast-up 3 hangs on the hook on bolt 1 that is connected with dielectric panel 4 by the spring 2 that hangs of its both sides again.Mast-up 3 is combined by thyristor carriage 3-1, radiator mast-up 3-2.Thyristor carriage 3-1 is the U type, and its front has several positioners on the appropriate location of semi-circumference, is used as the location of the metal flange insertion of flat thyristor 5 cathode terminals, so that flat thyristor 5 firmly to be installed; The reverse side of thyristor carriage 3-1 has suitable bending, is used to strengthen the rigidity of thyristor carriage 3-1, gives radiator mast-up 3-2 the location simultaneously when assembling.Radiator mast-up 3-2 is the corresponding matrix with thyristor carriage 3-1, and the top of its sidewall has the spring of hanging hanging hole, hangs spring 2 with connection, and its bottom has the hole of matching with gateway, radiator 6 water route, and radiator 6 two holes thus inserts mast-up 3.
Owing to adopted above-mentioned technical scheme, the beneficial effect that the present invention has is: 1, the mast-up of this mechanism adopts two stamping parts to be welded, and is simple in structure, is easy to make; 2, adopt spring to articulate, do not need the position of strict restriction thyristor and radiator, help the equilibrium of pressure between the axial alignment of whole thyristor valve string element and each series element; 3, the installation in mast-up of thyristor and radiator is push-pull structure, easy accessibility.
This hitch is changed for the maintenance of thyristor convenience is provided, especially at the thyristor number of series connection more for a long time, its effect is more outstanding.This mechanism has been arranged, and thyristor and radiator just can not drag when unclamping axial pressing force, all keep original position substantially, dismounting and change thyristor and radiator arbitrarily, and can not influence other element.
