2nd, the first relay 1 is connected to A phases, as shown in Figure 5；When needing to load 4 by A phases to B phases, 1 involution of the first relay is waited to bear
(although this mainly considers the first relay involution, physically A phases are already off, and load can be connect by electric arc after load cut-out
Lead to without really disconnecting, if the 3rd actuating of relay at this time is possible to cause A, B phase by arc starting and alternate short
Road), as shown in Figure 6；Then, the 3rd relay 3 acts, and completes the commutation of A to B, as shown in Figure 7；When needs will load 4 by A
When mutually to C phases, similarly, 1 involution of relay, after load break, as shown in Figure 6；Then, the second relay 2 acts, and completes A
To the commutation of C, as shown in Figure 8.
Referring to shown in Fig. 9 to Figure 12, load 4 is connected to B by the second relay 2, the first relay 1, the 3rd relay 3
Phase, as shown in Figure 9；When needing to load 4 by B phases to A phases, 3 involution of the 3rd relay, after cut-out loads (B phases power off),
As shown in Figure 10；Then, the first relay 1 acts, and completes the commutation of B to A, as shown in figure 11；When needs will load 4 by B phases
During to C phases, 3 involution of the 3rd relay, after cut-out loads (B phases power off), as shown in Figure 10；Then, the second relay 2 is dynamic
Make, complete the commutation of B to C, as shown in figure 12.
Referring to shown in Figure 13 to Figure 16, load 4 is connected to C phases by the second relay 2, as shown in figure 13；When needs will be negative
When carrying 4 by C phases to A phases, 2 involution of the second relay, after load break (C phases power off), as shown in figure 14；Then, first after
Electric appliance 1 acts, and completes the commutation of C to A, as shown in figure 15；When needing to load 4 by C phases to B phases, the second relay 2 is multiple
Return, after load break (C phases power off), as shown in figure 14；Then, the 3rd relay 3 acts, and completes the commutation of C to B, such as schemes
Shown in 16.
It is of course also possible to the first contact sets 11 of the first relay 1 are set to normally-closed contact group, the of the first relay 1
Two contact sets 12 are set to normally opened contact group, and the second relay 2 is also similar.
Because the first relay 1, the second relay 2 are 1HD types relay or Z-type relay, the 3rd relay 3 is single-tap
Point group relay, in no matter illustrating contacts status for any situation will not arbitrarily two-phase electricity is also turned on the phenomenon that, therefore will not
There is existing phase fault defect.
Above-mentioned simply presently preferred embodiments of the present invention not makees the present invention limitation in any form.It is although of the invention
It is disclosed above with preferred embodiment, however it is not limited to the present invention.Any those skilled in the art are not taking off
In the case of from technical solution of the present invention scope, all technical solution of the present invention is made perhaps using the technology contents of the disclosure above
Mostly possible changes and modifications are revised as equivalents equivalent embodiment.Therefore, it is every without departing from technical solution of the present invention
Content according to the technology of the present invention essence to any simple modifications, equivalents, and modifications made for any of the above embodiments, should all fall
