Embodiment
In order to make those skilled in the art better understand the present invention program, below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete description.
As Figure 1-3, a kind of fast arc extinction loaded capacity-regulated switch of type transformer, comprise high tension coil switched system and low-tension coil switched system, for one, in each phase, described high tension coil switched system comprises corner connection vacuum interrupter K2, star meets vacuum interrupter K1, it is parallel with the first transition vacuum interrupter Kg2 of the first transition resistance R2 and it is parallel with the 2nd transition vacuum interrupter Kg1 of the 2nd transition resistance R1, described corner connection vacuum interrupter K2 and the first transition vacuum interrupter Kg2 makes high tension coil present trilateral connection when closing a floodgate, star meets vacuum interrupter K1 and the 2nd transition vacuum interrupter Kg1 makes high tension coil present Astrocytic conditioned medium when closing a floodgate,
Concrete, in the present embodiment, described first transition vacuum interrupter Kg2 and described corner connection vacuum interrupter K2 is connected in series, and star meets vacuum interrupter K1 and the 2nd transition vacuum interrupter Kg1 and is connected in series.
When described high tension coil is in corner connection state, as shown in Figure 1, described corner connection vacuum interrupter K2 and the first transition vacuum interrupter Kg2 is combined floodgate state, and it is gate-dividing state that described star meets vacuum interrupter K1 and the 2nd transition vacuum interrupter Kg1;
And described high tension coil is converted in the process that star connects (namely by Large Copacity in the switching process of little capacity) by corner connection, each vacuum interrupter is by following sequential action:
First divide lock by the first transition vacuum interrupter Kg2;
Star then connects vacuum interrupter K2 close a floodgate;
Then lock is divided by corner connection vacuum interrupter K1;
Finally the 2nd vacuum interrupter Kg1 is closed a floodgate, complete conversion; As shown in Figure 2, described high tension coil is in star and connects state.
Referring specifically to Fig. 3, driving mechanism (driving mechanism can be permanent magnet mechanism) action time once is divided into tetra-time periods of T1-T4, and during the every action of permanent magnet mechanism one time, needing the place considering arc extinguishing to be also exactly that vacuum interrupter it's time to a point lock by closing a floodgate in whole process, vacuum interrupter then can be ignored by the arc produced in point lock to the process closed a floodgate;
Concrete, it being in the T1 time, Kg2 starts by combined floodgate to a point lock, and this period of T1-T2 then carries out arc extinguishing for Kg2; When arriving T2, Kg2 arc extinguishing terminates, and now K1 is closed by being disconnected to, and ignores owing to being disconnected to the arc of closed generation, and quenching time T2-T3 that namely it occupies is very short, as can be seen from the figure; After brief stay, K2 can be carried out by the operation of point lock that closes a floodgate, such as the T3 moment in figure; When arriving T4, Kg2 arc extinguishing terminates, and last Kg1 to combined floodgate, completes conversion by point lock.
