It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0036] Embodiment 1

[0037] Figure 1 is a structural block diagram of the power regulation module in the embodiment, refer to Figure 1The power regulation module is configured with a three-phase power port 100 , a plurality of pairs of first load interfaces 201 , a second load interface 202 , and a communication interface 300 .

[0038] Illustratively, in this embodiment, the three-phase power port 100 is used to access three-phase electricity, and the communication interface 300 is used to connect to the controller.

[0039] Illustratively, in this embodiment, the load of the power regulation module is a heating lamp, and the heating lamp is connected to the power regulation module through the first load interface 201 and the second load interface 202 .

[0040] Figure 2 is a wiring diagram of the heating lamp in the embodiment, refer to Figure 2 A pair of first load interfaces 201 and second load interfaces 202 can be connected to multiple heating lamp tubes L1~Ln. Inside the power regulation module, both ends of a heating lamp tube are connected to two-phase live wires of a three-phase power supply (for example, connected to the V and W phase live wires in the three-phase power supply).

[0041] After the heating lamp is connected to the three-phase power supply in the power regulation module through the first load interface and the second load interface, a load circuit is formed. Inside the power regulation module, each load circuit is equipped with a thyristor component (SCR1..., SCRn) and a fuse (F1..., Fn).

[0042] Exemplarily, the thyristor component in the load circuit is used to adjust the power of the corresponding heating lamp tube, and the fuse blows when the current in the load circuit is too large to avoid damage to the heating lamp tube.

[0043] refer to Figure 2 The power regulation module is also provided with a control chip 1, and the function of the control chip 1 includes controlling the thyristor components in the load circuit.

[0044] Combination Figure 1 and Figure 2 , take the heating lamp L1 as an example to explain the usage and working process of the power adjustment module:

Multiple thyristor components are configured inside the power regulation module, and one thyristor component is set in the load circuit of a heating lamp tube. The power of each heating lamp tube can be adjusted separately through the control chip, thereby achieving the purpose of individually adjusting the heating temperature of each heating lamp tube.

[0049] In addition, a fuse is configured in the load circuit inside the power regulation module, so that when the power regulation module is applied to the heating control system, there is no need to set a protective circuit breaker outside the power regulation module, nor is there a need to configure a solid-state relay for each heating lamp tube.

[0055] Inside the power regulation module, the heating lamps connected to the first load interface X1 and the second load interface X4 are connected in the same way as the three-phase power line. The two ends of each heating lamp are connected to the V-phase live wire and the W-phase live wire of the three-phase power supply respectively.

[0056] The heating lamps connected to the first load interface X2 and the second load interface X5 are connected in the same way as the three-phase power line. The two ends of each heating lamp are connected to the U-phase live wire and the W-phase live wire of the three-phase power supply respectively.

Therefore, when the power regulating module is applied to the heating control system, there is no need to lead out a power line from the copper busbar. The copper busbar and the power regulating module are connected through the power line. Since the copper busbar can directly supply power to the power regulating module, the wiring in the heating control system can be reduced.
