As an example, the main transformer spacing assembly 10 may include three isolation switches Q1, Q2 and Q3, each of which has one end connected to three access terminals, respectively, to cause one end of the isolation switch Q1 to be connected to the first bus bar BB01, one end of the isolation switch Q2 to be connected to the second bus bar BB02 and one end of the isolation switch Q3 to be connected to the third bus bar BB03, and the other ends of the three isolation switches Q1, Q2 and Q3 to be connected to each other; a circuit breaker Q0, one end of the circuit breaker Q0 is connected to the other ends of the three isolation switches Q1, Q2 and Q3, and the other end of the circuit breaker Q0 is connected to the outlet terminal of the main transformer spacing assembly 10; and a ground switch Q51, one end of the ground switch Q51 is connected to the other ends of the three isolation switches Q1, Q2 and Q3 and one end of the circuit breaker Q0 of the main transformer spacing assembly 10, and the other end of the ground switch Q51 is grounded.

The main transformer spacer assembly 10 may further include a ground switch Q52 connected to the other end of the circuit breaker Q0 and other switch assemblies Q9 and Q8, which may arrange the constituent parts of the main transformer spacer assembly 10 according to actual needs.

With the above-described structural design, when a bus bar failure occurs, for example, when one of three bus bars in operation fails or needs to be overhauled, the main transformer spacer assembly 10 connected to any one of the first bus bar BB01, the second bus bar BB02, and the third bus bar BB03 can be switched to be connected to the remaining one of the first bus bar BB01, the second bus bar BB02, and the third bus bar BB03 by using the first bus bar spacer assembly 1, the second bus bar spacer assembly 2, and the third bus bar spacer assembly 3. Specifically, each of the first, second and third bus bar spacer assemblies 1, 2 and 3 can switch the main transformer spacer assembly 10 connected to any one of the first, second and third bus bars BB01, BB02 and BB03 to the remaining one of the first, second and third bus bars BB01, BB02 and BB03 by switching on and off the first, second, third, and fourth disconnectors Q1, Q2, Q3-1, Q3-2, Q0 and the first and second grounding switches Q51 and Q52 thereof.

When the first bus bar BB01 fails, for example, when the first bus bar BB01 is overhauled, the outgoing line (the main transformer spacer 10) carried by the first bus bar BB01 will be switched to the second bus bar BB02 or the third bus bar BB03, and the switching operation interlocking operation in the switching operation mode will be described in detail below.

When the isolating switch Q1 of the main transformer spacing assembly 10 is closed and the isolating switches Q2 and Q3 are opened to connect the outgoing line load of the main transformer spacing assembly 10 with the first bus bar BB01 in the initial state, the main transformer spacing assembly 10 connected to the first bus bar BB01 is switched to the first operation mode in which the main transformer spacing assembly 10 is connected to the second bus bar BB 02:

as an example one of the first operation mode, the first isolation switch Q1, the second isolation switch Q2, and the first circuit breaker Q0 of the first bus bar spacer assembly 1 (corresponding to D05 in fig. 1 and 2) are turned on to achieve the equipotential between the first bus bar BB01 and the second bus bar BB02, the third isolation switch Q3-1 and the fourth isolation switch Q3-2 of the first bus bar spacer assembly 1 are turned off, and the first ground switch Q51 and the second ground switch Q52 of the first bus bar spacer assembly 1 are turned off.

Thereafter, the isolating switch Q2 of the main transformer isolating assembly 10 (corresponding to D01 of fig. 1 and 2) is closed (corresponding to the state of fig. 2), then the isolating switch Q1 of the main transformer isolating assembly 10 is opened, and then the first bus isolating assembly 1 is cut off, i.e., the first isolating switch Q1, the second isolating switch Q2 and the first circuit breaker Q0 are opened, thereby completing the switching of the main transformer isolating assembly 10 connected to the first bus bar BB01 to the main transformer isolating assembly 10 connected to the second bus bar BB02, and a person skilled in the art can clearly know how to perform this operation according to the structure of fig. 1 and the interlock logic diagram of fig. 2, which will not be described again.

As an example two of the first operation mode, the first disconnector Q1, the second disconnector Q2 and the first circuit breaker Q0 of the second bus bar spacer assembly 2 (corresponding to D15 in fig. 1 and 2) are turned on to achieve the equipotential between the first bus bar BB01 and the second bus bar BB02, the third disconnector Q3-1 and the fourth disconnector Q3-2 of the second bus bar spacer assembly 2 are turned off, and the first ground switch Q51 and the second ground switch Q52 of the second bus bar spacer assembly 2 are turned off.

In addition, as shown in fig. 1, a main transformer spacing assembly 10 is provided to the front bus-section group, in which case two disconnectors Q01A and Q01B of the first sectioning spacing assembly 4 (corresponding to D10.1 in fig. 1 and 2) and two disconnectors Q02A and Q02B of the third sectioning spacing assembly 6 (corresponding to D10.2 in fig. 1 and 2) and a circuit breaker Q0 for sectioning among the two sectioning spacing assemblies are turned on and ground switches Q51 and Q52 for sectioning are turned off.

Thereafter, the disconnector Q2 of the main transformer spacer assembly 10 is closed (corresponding to the state of fig. 2) and then the disconnector Q1 of the main transformer spacer assembly 10 is opened, then the second bus bar spacer assembly 2 is disconnected, i.e., the first disconnector Q1, the second disconnector Q2 and the first circuit breaker Q0 of the second bus bar spacer assembly 2 are opened, and it is determined whether to disconnect the third segment spacer assembly 6 and the first segment spacer assembly 4 according to the actual requirements (e.g., whether the front bus bar segment and the middle bus bar segment together supply the line load) and finally the switching of the main transformer spacer assembly 10 connected to the first bus bar BB01 to the main transformer spacer assembly 10 to the second bus bar BB02 is completed. It will be clear to those skilled in the art how to perform this operation according to the structure of fig. 1 and the interlocking logic diagram of fig. 2 and the actual need, and will not be described in detail herein.

In this example two of the first operation mode, the switching between the first bus bars BB01 and BB02 can be achieved by the second bus bar spacer assembly 2, and therefore, even when the first bus bar spacer assembly 1 fails, the switching between the first bus bars BB01 and BB02 can be achieved.

As an example three of the first operation mode, the first disconnector Q1, the second disconnector Q2 and the first circuit breaker Q0 of the third bus bar spacer assembly 3 (corresponding to D25 in fig. 1 and 2) are turned on to achieve the equipotential between the first bus bar BB01 and the second bus bar BB02, the third disconnector Q3-1 and the fourth disconnector Q3-2 of the third bus bar spacer assembly 3 are turned off, and the first ground switch Q51 and the second ground switch Q52 of the third bus bar spacer assembly 3 are turned off.

Thereafter, the disconnector Q2 of the main transformer spacer assembly 10 is closed (corresponding to the state of fig. 2) and then the disconnector Q1 of the main transformer spacer assembly 10 is opened, then the third bus bar spacer assembly 3 is cut off, i.e., the first disconnector Q1, the second disconnector Q2 and the first circuit breaker Q0 of the third bus bar spacer assembly 3 are opened, and it is determined whether to open the third and fourth segment spacer assemblies 6 and 7 and to open the first and second segment spacer assemblies 4 and 5 according to the actual need (e.g., whether the front, middle and rear bus bar segments together are needed to supply the line load), and finally the switching of the main transformer spacer assembly 10 connected to the first bus bar BB01 to the main transformer spacer assembly 10 to the second bus bar BB02 is completed. It will be clear to those skilled in the art how to perform this operation according to the structure of fig. 1 and the interlocking logic diagram of fig. 2 and the actual need, and will not be described in detail herein.

The above describes, by way of example, a case where the main transformer bay assembly 10 connected to the first bus bar BB01 is switched to the first operation mode where the main transformer bay assembly 10 is connected to the second bus bar BB02, and the operation thereof is similar to the above-described example for the switching of the second bus bar BB02 to the first bus bar BB01, and will not be repeated here.

When the main transformer bay assembly 10 connected to the first bus bar BB01 is switched to the second operation mode in which the main transformer bay assembly 10 is connected to the third bus bar BB03 with the isolating switch Q1 of the main transformer bay assembly 10 closed and the isolating switches Q2 and Q3 open in the initial state to connect the outgoing line load of the main transformer bay assembly 10 to the first bus bar BB 01:

Thereafter, the isolating switch Q3 of the main transformer spacer assembly 10 is closed (corresponding to the state of fig. 2) and then the isolating switch Q1 of the main transformer spacer assembly 10 is opened, and then the first bus bar spacer assembly 1 is cut off, i.e., the first isolating switch Q1, the fourth isolating switch Q3-2 and the first circuit breaker Q0 of the first bus bar spacer assembly 1 are opened, thereby completing the switching of the main transformer spacer assembly 10 connected to the first bus bar BB01 to the connection of the main transformer spacer assembly 10 to the third bus bar BB03.

In example two of the second operation mode, the switching between the first bus bars BB01 and BB03 can be achieved by the second bus bar spacer assembly 2, and therefore, even when the first bus bar spacer assembly 1 fails, the switching between the first bus bars BB01 and BB03 can be achieved.

In addition, as shown in fig. 1, a main transformer spacing assembly 10 is provided to the front bus-section group, in which case two disconnectors of the first, second, seventh and eighth section spacing assemblies 4, 5, 8 and 9 (corresponding to D20.3 in fig. 1 and 2) and a circuit breaker Q0 for the section are turned on and ground switches Q51 and Q52 for the section are turned off.

Thereafter, the disconnector Q3 of the main transformer spacer assembly 10 is closed (corresponding to the state of fig. 2) and then the disconnector Q1 of the main transformer spacer assembly 10 is opened, then the third bus bar spacer assembly 3 is disconnected, i.e., the first disconnector Q1, the second disconnector Q2 and the first circuit breaker Q0 of the third bus bar spacer assembly 3 are opened, and it is determined whether to disconnect the seventh and eighth segment spacer assemblies 8 and 9 and disconnect the first and second segment spacer assemblies 4 and 5 according to the actual need (e.g., whether the front, middle and rear bus bar segments together are needed to supply the line load), finally completing the switching of the main transformer spacer assembly 10 connected to the first bus bar BB01 to the main transformer spacer assembly 10 to the third bus bar BB03. It will be clear to those skilled in the art from the structure of fig. 1 and the interlocking logic diagram of fig. 2 how to perform this operation, and will not be described in detail herein.

The case of switching the main transformer bay assembly 10 connected to the first bus bar BB01 to the second operation mode in which the main transformer bay assembly 10 is connected to the third bus bar BB03 is described above by way of example, and the operation thereof is similar to the above-described example for the switching of the third bus bar to the first bus bar, and will not be repeated here.

When the main transformer bay assembly 10 connected to the second bus bar BB02 is switched to the third operation mode in which the main transformer bay assembly 10 is connected to the third bus bar BB03 with the isolating switch Q2 of the main transformer bay assembly 10 in the initial state being closed and the isolating switches Q1 and Q3 being opened to connect the outgoing line load of the main transformer bay assembly 10 to the second bus bar BB 02:

It will be clear to those skilled in the art from the structure of fig. 1 and the interlocking logic diagram of fig. 2 how to perform this operation, and will not be described in detail herein.

As an example two of the third operation mode, the second isolation switch Q2, the third isolation switch Q3-1, and the first circuit breaker Q0 of the second bus bar spacer assembly 2 are turned on, the fourth isolation switch Q3-2 and the first isolation switch Q1 of the second bus bar spacer assembly 2 are turned off, and the first ground switch Q51 and the second ground switch Q52 of the second bus bar spacer assembly 2 are turned off.

Thereafter, the isolating switch Q3 of the main transformer spacer assembly 10 is closed (corresponding to the state of fig. 2) and then the isolating switch Q2 of the main transformer spacer assembly 10 is opened, and then the second bus bar spacer assembly 2 is cut off, i.e., the second isolating switch Q2, the third isolating switch Q3-1 and the first circuit breaker Q0 of the second bus bar spacer assembly 2 are opened, thereby completing the switching of the main transformer spacer assembly 10 connected to the second bus bar BB02 to the connection of the main transformer spacer assembly 10 to the third bus bar BB03. It will be clear to those skilled in the art from the structure of fig. 1 and the interlocking logic diagram of fig. 2 how to perform this operation, and will not be described in detail herein.

In this example two of the third operation mode, switching between the second bus bar BB02 and the third bus bar BB03 can be achieved by the second bus bar spacer assembly 2, and therefore, even when the first bus bar spacer assembly 1 fails, switching between the second bus bar BB02 and the third bus bar BB03 can be achieved.

As an example three of the third operation mode, the second isolation switch Q2, the third isolation switch Q3-1, and the first circuit breaker Q0 of the third bus bar spacer assembly 3 are turned on, the fourth isolation switch Q3-2 and the first isolation switch Q1 of the third bus bar spacer assembly 3 are turned off, and the first ground switch Q51 and the second ground switch Q52 of the third bus bar spacer assembly 3 are turned off.

Thereafter, the disconnector Q3 of the main transformer spacer assembly 10 is closed (corresponding to the state of fig. 2) and then the disconnector Q2 of the main transformer spacer assembly 10 is opened, then the third bus bar spacer assembly 3 is disconnected, i.e., the second disconnector Q2, the third disconnector Q3-1 and the first circuit breaker Q0 of the third bus bar spacer assembly 3 are opened, and it is determined whether to disconnect the fifth and sixth segment spacer assemblies 8 and 9 and disconnect the third and fourth segment spacer assemblies 6 and 7 according to the actual need (e.g., whether the front, middle and rear bus bar segments together are needed to supply the line load), finally completing the switching of the main transformer spacer assembly 10 connected to the second bus bar BB02 to the main transformer spacer assembly 10 to the third bus bar BB03.

The case of switching the main transformer bay assembly 10 connected to the second bus bar BB02 to the case of connecting the main transformer bay assembly 10 to the third bus bar BB03 is described above by way of example, and the operation thereof is similar to the above-described example for the switching of the third bus bar to the second bus bar, and will not be repeated here.

The above example is directed to the main transformer spacer assembly 10 provided to the front bus-section group, but alternatively or additionally, the main transformer spacer assembly 10 may be provided to the middle bus-section group and the rear bus-section group, for example, in the case of the main transformer spacer assembly 10 provided to the middle bus-section group, the inverted bus operation may be performed using the first bus-bar spacer assembly 1 or the third bus-bar spacer assembly 3, in the case of the inverted bus operation using the first bus-bar spacer assembly 1, the segment spacer assembly connecting the front bus-section and the middle bus-section may be turned on, and in the case of the inverted bus operation using the third bus-bar spacer assembly 3, the segment spacer assembly connecting the middle bus-section and the rear bus-section may be turned on.
