R2, the common end of the normally closed contact of the output contactor KM3, the other end of the normally closed contact of the output contactor KM3 is connected to one end of the coil of the bypass contactor KM2, the other end of the normally open contact JZ12 of the intermediate relay JZ1 is connected in series with the normally closed contact of the bypass contactor KM2, and then connected to the common end of the coil of the input contactor KM1, the main operation indicator light HR1, and the coil of the output contactor KM3, the coil JZ01 of the intermediate relay JZ0, the indicator light HG, the coil of the input contactor KM1, the main operation indicator light HR1, the coil of the output contactor KM3, the coil of the bypass contactor KM2, the bypass operation indicator light HR2, The N terminal of the light control module GK and the PN terminal of the main controller M are connected to the N terminal of the three-phase AC power; the V5, GND, CANH, CANL, and TEM1 terminals of the intelligent transformer BS are respectively connected to the V5, GND, CANH, CANL, and L4 terminals of the main controller M, and the TEM2 terminal is connected to the LCOM of the main controller M, the normally open contact of the input contactor KM1, the normally open contact of the bypass contactor KM2, the normally open contact of the output contactor KM3, the common terminal of the C2 terminal of the light control module GK, the normally open contact of the input contactor KM1, the normally open contact of the bypass contactor KM2, the normally open contact of the output contactor KM3, and the light control module GK. The C1 terminal of K is connected to the L1, L2, L3, and L5 terminals of the main controller M respectively. The PGND terminal of the main controller is connected to the common terminal of the coil JZ11 of the intermediate relay JZ1, the coil JZ21 of the intermediate relay JZ2, and the coil JZ31 of the intermediate relay JZ3. The V24 terminal of the main controller M is connected in series with the normally closed contact JZ03 of the intermediate relay JZ0 and then to the R11, R21, and R41 terminals. The R12, R22, and R42 of the main controller M are connected to one end of the intermediate relay coil JZ11, JZ21, and JZ31 respectively. The intelligent transformer BS and the main controller M realize internal communication of the system through the CANH and CANL wires.

[0010] When using this utility model, connect it to the primary circuit and refer to Figure 1The three-phase power supply of the primary circuit is connected to the input terminals A, B, C, and N of the smart transformer BS through the input contactor KM1, and is connected to the output terminals A, B, and C of the smart transformer BS through the output contactor KM3 to output electrical energy. The three-phase power supply directly outputs electrical energy through the bypass contactor KM2 as a bypass.

[0011] When transfer switch SA is in automatic bypass mode, master controller M implements output control for the astronomical clock or optical signal input and output control for the photoelectric controller. Master controller M outputs 24V power from terminal V24. This power flows through the normally closed contact JZ03 of intermediate relay JZ0, connecting terminals R41 and R42 of master controller M and coil JZ31 of intermediate relay JZ3, energizing intermediate relay JZ3. Control circuit power flows through terminals 1 and 2 of transfer switch SA, connecting the normally open contact JZ32 of intermediate relay JZ3, and connecting the normally closed contact of output contactor KM3. This energizes the coil of bypass contactor KM2, energizing its main contacts, lighting the bypass operation indicator, and outputting power. Controller M also monitors the feedback signal from bypass contactor KM2 to verify contactor operation. If it fails to operate, an alarm signal will be issued.

[0012] When the transfer switch SA is in the manual bypass state, the normally closed contact JZ03 of the intermediate relay JZ0 is disconnected, there is no 24V power output, the control circuit power supply is turned on through terminals 3 and 4 of the transfer switch SA, the coil JZ01 of the intermediate relay JZ0 is energized, the intermediate relay JZ0 is attracted, the normally open contact JZ02 of the intermediate relay JZ0 is turned on, the normally closed contact of the output contactor KM3 is turned on, the coil of the bypass contactor KM2 is energized, the main contact of the bypass contactor KM2 is turned on, the bypass operation indicator light is on, and electrical energy is output.

[0013] When the transfer switch SA is in the stop state, the stop indicator light HG is on and the control circuit has no output.

[0014] When the transfer switch SA is in the main circuit state:

[0015] 1. Master controller M implements output control for the astronomical clock or optical signal input / output control for the photoelectric controller. The master controller's V24 terminal outputs 24V power, which conducts through the normally closed contact JZ03 of intermediate relay JZ0. This conducts through terminals R11 and R12 of master controller M, energizing coil JZ11 of intermediate relay JZ1 and closing it. The control circuit power is then conducted through terminals 5 and 6 of transfer switch SA, conducting the normally open contact JZ12 of intermediate relay JZ1 and the normally closed contact of bypass contactor KM2. This energizes the coil of input contactor KM1, closing its main contacts. This energizes the coil of output contactor KM3, closing its main contacts. The main circuit operation indicator HR1 illuminates, and power is output. The controller also checks the feedback signal from output contactor KM3 to verify contactor operation. If it fails to operate, an alarm signal will be issued.

[0016] 2. The master controller M can also directly control the bypass contactor to close based on other protection functions, such as the internal temperature of the smart transformer BS. The master controller M outputs 24V power at its V24 terminal, which conducts through the normally closed contact JZ03 of the intermediate relay JZ0. This energizes the coil JZ21 of the intermediate relay JZ2, closing the intermediate relay JZ2. The control circuit power is then connected through points 7 and 8 of the transfer switch SA. This energizes the normally open contact JZ22 of the intermediate relay JZ2, the normally closed contact of the output contactor KM3, and the coil of the bypass contactor KM2. This energizes the bypass operation indicator HR2, illuminates the bypass contactor KM2 main contacts, and begins outputting power. The controller also monitors the feedback signal from the bypass contactor KM2 to verify contactor operation. If it fails to operate, an alarm will be issued.
