[0041] In order to enable people in the technical field to better understand the present solution, the technical solution in the embodiment of the present solution will be clearly described below in conjunction with the drawings in the embodiment of the present solution. Obviously, the described embodiment is an embodiment of a part of the present solution, not all of the embodiments. Based on the embodiments in the present solution, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present solution.

[0042] The term "including" and any other variations in the specification and claims of this solution and the above drawings mean "including but not limited to", and is intended to cover non-exclusive inclusions and is not limited to the examples listed in the text. In addition, the terms "first" and "second" are used to distinguish different objects, not to describe a specific order.

[0043] The following is a detailed description of the implementation of the present disclosure in conjunction with the specific drawings:

[0044] Figure 1 This is a schematic diagram of the structure of a power regulator provided by an embodiment of the present disclosure. Figure 1 , the power regulator comprises:

[0045] A first control board 11, a second control board 20, a thyristor module 30, a plurality of sensor modules 40 and a fuse 50;

[0046] A plurality of sensor modules 40 are respectively connected to the first control board 11 and the second control board 20;

[0047] The first control board 11 is connected to the thyristor module 30, the second control board 20 is connected to the thyristor module 30, the thyristor module 30 is connected to the fuse 50, and the thyristor module 30 is also connected to the load;

[0048] The first control board 11 is connected to the second control board 20;

[0049] The plurality of sensor modules 40 are configured to collect property parameters of the thyristor module 30;

[0050] The first control board 11 is configured to control the thyristor module 30 to perform a main heating operation mode, and the second control board 20 is configured to control the thyristor module 30 to perform an auxiliary heating operation mode.

[0051] In this embodiment, the first control board 11 is connected to the second control board 20, and the first control board 11 and the second control board 20 are placed in parallel on the control tray. Below the control tray is a thyristor module 30, the power input end of the thyristor module 30 is connected to the fuse 50, and the power output end is connected to the heating load.

[0052] Multiple sensor modules 40 are used to collect property parameters of the thyristor module 30, such as temperature, current, voltage, etc., and send the property parameters to the first control board 11 and the second control board 20 respectively. The first control board 11 and the second control board 20 can control the thyristor module 30 according to the property parameters to put it in different working modes.

[0053] For example, when the user sets the main heating mode, and the temperature data collected by the multiple sensor modules 40 is not within the temperature range of the main heating (generally 100°C to 300°C), the first control board 11 can control the thyristor module 30 to perform the main heating mode according to the temperature data collected by the multiple sensor modules 40. When the user sets the auxiliary heating mode, and the temperature data collected by the multiple sensor modules 40 is not within the temperature range of the auxiliary heating (generally 40°C to 150°C), and is lower than the minimum temperature of the auxiliary heating, the second control board 20 can control the thyristor module 30 to perform the auxiliary heating mode according to the temperature data collected by the multiple sensor modules 40.

[0054] In special cases, such as when the thyristor module 30 in the main heating mode cannot meet the heating demand, the second control board 20 can control the thyristor module 30 to start the auxiliary heating mode to provide additional heating capacity.

[0055] The thyristor module 30 is also connected to the fuse 50, which is a circuit protection device. When an overcurrent phenomenon occurs during the operation of the thyristor, such as excessive load or reduced circuit impedance, the fuse 50 will automatically blow to protect the thyristor module 30 from damage. When the fuse 50 identifies a short circuit fault at the output end of the thyristor module 30, the circuit can be cut off in time to prevent the short circuit current from causing serious damage to the equipment.

[0056] It can be concluded from the above that, on the one hand, the present disclosure sets two control boards, wherein the first control board 11 can control the thyristor module 30 to execute the main heating heating mode, and the second control board 20 can control the thyristor module 30 to execute the auxiliary heating heating mode. In special circumstances, the main heating mode and the auxiliary heating mode can be operated simultaneously to meet the normal heating demand of the load.

[0057] On the other hand, the first control board 11 and the second control board 20 in the present disclosure can also dynamically adjust the working mode of the thyristor module 30 according to the property parameters collected by the multiple sensor modules 40 to meet actual needs.

[0058] In one embodiment of the present disclosure, the thyristor module 30 includes:

[0059] A first group of thyristor circuits and a second group of thyristor circuits;

[0060] The first group of thyristor circuits is connected to the first control board 11, and the second group of thyristor circuits is connected to the second control board 20;

[0061] The first group of thyristor circuits are connected to the fuse 50 and the load respectively; the second group of thyristor circuits are connected to the fuse 50 and the load respectively.

[0062] In this embodiment, the first group of thyristor circuits is connected to the first control board 11 and can be used for main heating control; the second group of thyristor circuits is connected to the second control board 20 and is used for auxiliary heating control. The first group of thyristor circuits and the second group of thyristor circuits can work independently or together.

[0063] The first set of thyristor circuits is the core part of the power regulator, which usually needs to be able to withstand large currents and voltages and have high stability and reliability. The second set of thyristor circuits is the auxiliary heating part of the power regulator, which is used to provide additional heating capacity when the first set of thyristor circuits cannot meet the demand, or as a backup when the first set of thyristor circuits fails. The second set of thyristor circuits is smaller than the first set of thyristor circuits and has relatively low power, but is more flexible and can respond quickly to quickly replenish heating energy when needed.

[0064] In one embodiment of the present disclosure, the power regulator further includes:

[0065] Communication module;

[0066] The communication module is connected to the first control board 11 and the second control board 20 respectively;

[0067] The first control board 11 is configured to control the operation of the first group of thyristor circuits according to the instructions received by the communication module; the second control board 20 is configured to control the operation of the second group of thyristor circuits according to the instructions received by the communication module.

[0068] In this embodiment, the communication module also includes wired communication and wireless communication. The first control board 11 and the second control board 20 can receive external instructions through the communication module to control the thyristor module 30. For example, the user sends instructions to the first control board 11 and the second control board 20 to execute the main heating mode through wireless communication. At this time, the second control board 20 does not need to execute the instructions. The first control board 11 controls the first group of thyristor circuits according to the instructions to put them in the main heating working mode. The user sends instructions to the first control board 11 and the second control board 20 to execute the auxiliary heating mode through wired communication. At this time, the first control board 11 does not need to execute the instructions. The second control board 20 controls the second group of thyristor circuits according to the instructions to put them in the auxiliary heating working mode.

[0069] Both the first control board 11 and the second control board 20 can adjust the heat output by changing the trigger angle of the thyristor. For example, the first control board 11 can reduce the trigger angle of the thyristor in the first group of thyristor circuits, so that more current can pass through the thyristor, thereby increasing the heat output; the second control board 20 can increase the trigger angle of the thyristor in the second group of thyristor circuits, thereby limiting the current passing through the thyristor and reducing the heat output.

[0070] In this embodiment, both the first control board 11 and the second control board 20 can receive external signals to control the thyristor module 30, making the operation simpler and more convenient.

[0071] In one embodiment of the present disclosure, the first group of thyristor circuits and the second group of thyristor circuits each include a plurality of thyristor circuits.

[0072] In this embodiment, the first group of thyristor circuits may have 7 thyristor circuits, and the second group of thyristor circuits may have 3 thyristor circuits.

[0073] In one embodiment of the present disclosure, there are multiple fuses 50 , and each thyristor circuit is connected to a fuse 50 .

[0074] In this embodiment, there are multiple fuses 50, and each thyristor circuit is connected to a fuse 50. The fuse 50 is connected to the power input end of each thyristor circuit, and can play a role in short-circuit protection for each thyristor circuit.

[0075] In one embodiment of the present disclosure, the plurality of sensor modules 40 include:

[0076] a first sensor module and a second sensor module;

[0077] The first sensor module is connected to the first control board 11 and the second control board 20 respectively; the second sensor module is connected to the first control board 11 and the second control board 20 respectively.

[0078] In this embodiment, the plurality of sensor modules 40 include a first sensor module and a second sensor module. The first sensor module can send the collected attribute parameters to the first control board 11 and the second control board 20; the second sensor module can also send the collected attribute parameters to the first control board 11 and the second control board 20. Setting two sensor modules can increase measurement accuracy and enhance system reliability.

[0079] The first sensor module and the second sensor module measure data in the same area.

[0080] For example, the first control board 11 can calculate the average value of the temperature data collected by the first sensor module and the second sensor module, and control the working state of the thyristor module 30 according to the average value. This method can reduce the measurement error of a single sensor module and improve the overall measurement accuracy. For another example, when the first sensor module fails and cannot measure, the second sensor module can also work normally, thereby ensuring the stability and reliability of the system.

[0081] In one embodiment of the present disclosure, the first sensor module includes:

[0082] a first temperature sensor, a first voltage sensor, and a first current sensor;

[0083] The second sensor module includes:

[0084] a second temperature sensor, a second voltage sensor, and a second current sensor.

[0085] In this embodiment, the first temperature sensor in the first sensor module and the second temperature sensor in the second sensor module can both measure the temperature of the thyristor module 30, the first voltage sensor and the second voltage sensor can both measure the voltage across the thyristor module 30, and the first current sensor and the second current sensor can both measure the current flowing through the thyristor module 30.

[0086] The current sensor and the voltage sensor are used together to realize comprehensive monitoring and control of the thyristor module 30. The first temperature sensor and the second temperature sensor can ensure the working efficiency of the thyristor module 30.

[0087] In one embodiment of the present disclosure, the power regulator further includes:

[0088] Radiator 60, fan 70 and fan bracket 80;

[0089] The fan 70 is connected to the first control board 11 and the second control board 20 respectively; the radiator 60 is connected to the fan 70 , and the fan 70 is fixed on a fan bracket 80 .

[0090] In this embodiment, when the temperature data received by the first control board 11 and the second control board 20 exceeds a preset value, the fan 70 can be controlled to start and discharge the heat generated by the thyristor module 30 when it is working. In order to improve the heat dissipation effect, a heat sink 60 is also added. The heat sink 60 can quickly conduct and dissipate the heat generated by the thyristor module 30 to the surrounding environment to ensure the normal working temperature of the thyristor module 30 and extend its service life.

[0091] In one embodiment of the present disclosure, the power regulator further includes:

[0092] Inlet terminal plate 90 and outlet terminal plate 100;

[0093] The line-in terminal plate 90 and the line-out terminal plate 100 are disposed on both sides of the thyristor module 30 .

[0094] In this embodiment, the power line of the external power source can be connected from the line inlet of the outlet terminal plate 100 to the front end of the fuse 50 at the power input end of the thyristor module 30, and the output end of the thyristor module 30 is connected to the heating load.

[0095] The independent distribution of the power regulator's inlet and outlet can avoid the signal lines and power lines being too dense in the same area, thereby reducing the interference between them. This helps to improve the stability and reliability of the equipment and reduce the possibility of failure.

[0096] Independently distributed cable inlets and outlets can make wiring simpler and clearer, helping to simplify subsequent maintenance and repair work.

[0097] In one embodiment of the present disclosure, the user can set control parameters by pressing buttons on the control panel of the power regulator cover, and the control parameters can be sent to the first control board 11 and the second control board 20 through wired communication. The first control board 11 and the second control board 20 control the thyristor module 30 to work according to the control parameters. A phase partition is provided between each two thyristor circuits in the thyristor module 30 to prevent short circuits and flame retardancy.

[0098] In one embodiment of the present disclosure, the length of an existing independent product containing 7 thyristor circuits is 380 mm, and the length of an independent product containing 3 thyristor circuits is 110 mm. With the product installation spacing, the total length is nearly 550 mm. The power regulator in this embodiment includes 7 thyristor circuits for main heating and 3 thyristor circuits for auxiliary heating. The overall dimensions are 450 mm long, 310 mm wide, and 271.5 mm high, which is nearly 100 mm shorter than the total length of the existing two independent products, effectively saving machine installation space and reducing the overall material cost of the product. Each thyristor circuit is connected to a fuse 50, which has the function of short-circuit protection.
