Description
Technical field
The utility model relates to a kind of thyristor valve, particularly about a kind of thyristor valve with component top-pressure mechanism.
Background technology
Thyristor valve is the core component of electric power system controllable series compensator and static compensating device.Along with the continuous development of power electronic technology, increasing as the thyristor of core parts, the required mechanical pressure of its work is also increasing.It requires to keep the table top of thyristor parallel and concentric with the table top of radiator when mounted; 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 must reach necessary requirement, therefore need provide a kind of thyristor component roof pressure mechanical mechanism that can satisfy above-mentioned requirements.At present domestic do not have this type of to install, and the version of other close device is single bolt at the center roof pressure, and roof pressure power is born by a bolt, and maintenance effort and higher to the requirement of strength of roof pressure bolt is installed.
Summary of the invention
At the problems referred to above, the purpose of this utility model provides a kind of simple to operate laborsaving, the thyristor valve with component top-pressure mechanism that installation difficulty reduces.
For achieving the above object, the utility model is taked following technical scheme: a kind of thyristor valve with component top-pressure mechanism, it comprises the thyristor valve string of being made up of at interval a plurality of thyristors and radiator, be arranged on dish spring, the ring flange of described thyristor valve string one end and be connected dish spring guide rod on the ring flange, and the top-pressure mechanism that is arranged on the described thyristor valve string other end, it is characterized in that: described top-pressure mechanism is a component top-pressure mechanism, and it comprises a roof pressure guide rod; Described roof pressure guide rod outside is provided with a fairlead, connect a ring flange in described fairlead end by screw, end at described ring flange connects a roof pressure dish by three roof pressure bolts, the end that described roof pressure dish contacts with described roof pressure guide rod is a ballhead, and the ring flange of described component top-pressure mechanism is connected upper and lower two fixed heads with the ring flange of described dish spring one side by bolt.
Described fairlead is concentric by seam location and maintenance with described ring flange.
Described roof pressure bolt is three, and it is on the circumference in the center of circle with the disk center that described roof pressure bolt is evenly distributed on described roof pressure card.
The utility model is owing to take above technical scheme, it has the following advantages: 1, top-pressure mechanism of the present utility model is because an end that contacts with the roof pressure guide rod at the roof pressure dish adopts a ballhead, and by the roof pressure power of three roof pressure bolt carryings to thyristor and radiator, therefore both made the roof pressure card also can not make roof pressure power along the thyristor center application of force with axis normal, keep the table top of thyristor parallel and concentric with the table top of radiator, thereby improved the processing safety when compressing thyristor effectively, reduced requirement of strength the roof pressure bolt.2, the utility model is owing to adopt bolt mechanism to compress operation, therefore not only its required apply to screw power less, it is laborsaving to construct, and simple to operate, safe and reliable.The utility model is simple in structure, and is easy for assembly, disassembly and maintenance, and it can be widely used in electric power system controllable series compensator and the static compensating device.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail.
As shown in Figure 1, the utility model comprises roof pressure guide rod 1, on roof pressure guide rod 1, be arranged with a fairlead 2, be matched in clearance between roof pressure guide rod 1 and the fairlead 2, roof pressure guide rod 1 can be done along fairlead 2 to endwisely slip and keeps the two concentric, one end of fairlead 2 is by screw 3 mounting flanges 4, and fairlead 2 also keeps concentric with ring flange 4 by seam 21,41 location.Ring flange 4 connects a roof pressure dish 6 by three roof pressure bolts 5, and the end that roof pressure dish 6 contacts with roof pressure guide rod 1 is a ballhead 61, and roof pressure dish 6 is connected on the ring flange 4 by three roof pressure bolts 6, and the ballhead 61 of roof pressure dish 6 is pressed on the roof pressure guide rod 1.
As Fig. 2, shown in Figure 3, three roof pressure bolts 6 are the center of circle with the disk center, are evenly distributed on the roof pressure card 5, and the O of roof pressure disk center is a stress point.
As shown in Figure 3, Figure 4, apply power F when the A point
1The time, the mid point M point of BC is a fulcrum, the O point is a stress point; The O point is the center of equilateral Δ ABC.
AM＝3OM F
1＝1/3F
Hence one can see that, in afterburner process, and the power F that applies
1Be 1/3 of required roof pressure power F.
As shown in Figure 5, when component top-pressure mechanism of the present utility model used, at first the end with roof pressure guide rod 1 of the present utility model connected thyristor valve string 7, and thyristor valve string 7 is contacted at interval by a plurality of thyristors 71 and radiator 72 and formed.The other end of thyristor valve string 7 connects a dishful of spring 8, the other end of dish spring 8 withstands on one and is connected with on the ring flange 10 of stage clip guide rod 9, ring flange 4 with ring flange 10 and the utility model top-pressure mechanism, be connected on upper and lower two fixed heads 12 by bolt 11, screw three roof pressure bolts 6 of the present utility model then in turn.Because the stressed card of output of roof pressure dish 5 of the present utility model is a sphere, in the process that screws three roof pressure bolts 6 in turn, both made the roof pressure card also can not make roof pressure power along the thyristor 71 center application of forces with axis normal, keep the table top of thyristor 71 parallel and concentric with the table top of radiator 72, make pressure be evenly distributed on the end face contact area of roof pressure guide rod 1, thereby reach the purpose that compresses thyristor.
