Include two groups of Geneva mechanisms 1.1,1.2, moving contact 2.1,2.2, static contact group 3.1,3.2, insulating mounting mainboard 4, bearing 5.1,
5.2, Geneva mechanism 1.1,1.2 includes driver plate 6.1,6.2 and sheave 7.1,7.2.
Driver plate 6.1,6.2 is enclosed on the transmission square shaft of on-load voltage regulating switch at different angles by bearing 5.1,5.2 respectively
On 11, sheave 7.1,7.2 is sleeved in the fixing axle 8 of insulating mounting mainboard 4, and static contact group 3.1 and 3.2 can be integrated
Sets of contacts, through being installed in the groove of insulating mounting mainboard 4 or two groups of static contact groups 3.1 and 3.2, its is corresponding
Static contact links together two-by-two, in the groove for being individually fixed in the both sides of insulating mounting mainboard 4.In static contact group 3.1,3.2
The quantity of static contact 9 is determined according to pressure regulation gear number, as shown in figure 3, the quantity of static contact 9 has the stationary contact in 9, i.e. Fig. 3
Head is identified with 9.19.9, represents that selecting switch component has 9 gears, Fig. 3 illustrates the selecting switch of on-load voltage regulating switch
The static contact 9.1 ... 9.9 of component side, the static contact 9.1 ... 9.9 shown in the static contact and Fig. 3 of selecting switch component opposite side
It is just the same and corresponded with it, the static contacts of both sides can be it is integral can also be that static contact correspondence is connected two-by-two.It is dynamic
Contact 2.1 is fixed on sheave 7.1, and the moving contact 2.2 of opposite side is fixed on sheave 7.2, in the both sides of insulating mounting mainboard 4 also
There is the tension disc 10.1,10.2 of fixed contact outlet.
It can be seen from Fig. 1 and Fig. 2, the He of driver plate 6.1 on on-load voltage regulating switch transmission square shaft 11 is sleeved on different angles
The rotation of driver plate 6.2, respectively driving sheave 7.1 and the different sequential of sheave 7.2, sheave 7.1 and sheave 7.2 drive moving contact respectively
2.1 and the action of the different sequential of moving contact 2.2, its connection conversion between two adjacent static contacts 9 is completed, completion has load
The pressure regulation gear selection that tap changer is not powered off.
Described above is only the preferred embodiment of the present invention, it is noted that come for those skilled in the art
