Description
Technical Field

[0002] In the use of existing PERC (Passivated Emitter Rear Cell) and TOPCON (Tunnel Oxide Passivated Contact Solar Cell) plasma deposition furnaces, the load infrared heating lamp tube is subjected to high temperature and high pressure environment for a long time, which can easily damage the quartz sleeve of the outer shell, leading to a short circuit in the heating wire. This causes the thyristor inside the three-phase power regulator to break down and short-circuit instantaneously. After the three-phase power regulator is short-circuited and burned out, it will cause damage to precision spare parts such as temperature control module, flow meter, and butterfly valve connected in parallel in the circuit.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0036] See appendix Figure 1 , Figure 1 This is a schematic diagram of the main components of a three-phase power adjustment device according to an embodiment of the present invention. Figure 1 As shown in the embodiment of this utility model, the three-phase power adjustment device may include a three-phase power regulator 1, a surge protector 4, a spare parts module 2, and a PLC module 3; the first terminal (DB-) of the 485 communication line of the three-phase power regulator 1 is connected to the first terminal of the surge protector, and the second terminal (DA+) of the 485 communication line is connected to the second terminal of the surge protector 4; the third terminal of the surge protector 4 is connected to the first terminal of the spare parts module 2, and the fourth terminal of the surge protector 4 is connected to the second terminal of the spare parts module 2; the third terminal of the surge protector 4 is connected to the first terminal (DB-) of the PLC, and the fourth terminal of the surge protector 4 is connected to the second terminal (DA+) of the PLC module 3.
[0037] like Figure 1As shown, the three-phase power regulator 1 includes a thyristor and an infrared heating element. Under high temperature and high pressure, the infrared heating element's heating wire may short-circuit, leading to a momentary breakdown and short circuit of the internal thyristor. The short-circuit current generated when the thyristor momentarily breaks down can damage the spare parts in the parallel-connected spare parts module 2. In this embodiment, a surge protector 4 can be installed between the terminals of the 485 communication lines of the three-phase power regulator 1, spare parts module 2, and PLC module 3. The surge protector 4 outputs the 485 communication signal to the spare parts module 2 and PLC module 3, preventing damage to the spare parts in the spare parts module 2 from the momentary short-circuit current.
[0038] In one implementation, such as Figure 1 As shown, phases A, B, and C of the three-phase power regulator 1 can all be connected to fuses. In one example, the fuse is a 150A fuse.
[0039] In one implementation, such as Figure 1 As shown, spare parts module 2 may include a temperature control unit, a butterfly valve 22, and a flow meter 23. The first terminals (DB-) of the temperature control unit 21, butterfly valve 22, and flow meter 23 are interconnected to form the first terminal of spare parts module 2; the second terminals (DA+) of the temperature control unit 21, butterfly valve 22, and flow meter 23 are interconnected to form the second terminal of spare parts module 2. Since the temperature control unit 21, butterfly valve 22, and flow meter 23 are all connected to the surge protector 4, the surge protector 4 can protect the temperature control unit 21, butterfly valve 22, and flow meter 23, preventing instantaneous short-circuit current loss to the temperature control unit 21, butterfly valve 22, and flow meter 23.
[0040] In one embodiment, the surge protector 4 may be equipped with an indicator light that illuminates when the surge protector 4 malfunctions. For example, the indicator light will illuminate in the event of a transient short-circuit current to indicate a circuit fault and facilitate maintenance.
[0041] With the above configuration, the three-phase power adjustment device of this utility model embodiment includes a three-phase power regulator 1, a surge protector 4, a spare parts module 2, and a PLC module 3. The first terminal of the 485 communication line of the three-phase power regulator 1 is connected to the first terminal of the surge protector 4, and the second terminal of the 485 communication line is connected to the second terminal of the surge protector 4. The third terminal of the surge protector 4 is connected to the first terminal of the spare parts module 2, and the fourth terminal of the surge protector 4 is connected to the second terminal of the spare parts module 2. The third terminal of the surge protector 4 is connected to the first terminal of the PLC module 3, and the fourth terminal of the surge protector 4 is connected to the second terminal of the PLC module 3. Through this configuration, this utility model embodiment can protect the spare parts of the spare parts module 2 and the PLC module 3 through the surge protector 4, preventing damage to the spare parts of the spare parts module 2 and the PLC module 3 by instantaneous short-circuit current, thus achieving effective protection for the spare parts of the spare parts module 2 and the PLC module 3.
[0042] In one implementation, such as Figure 1 As shown, the three-phase power adjustment device may further include a circuit protector 5; the first terminal of the circuit protector 5 is connected to the first analog terminal (C1+) of the three-phase power adjuster 1, the second terminal of the circuit protector 5 is connected to the second analog terminal (C1-) of the three-phase power adjuster 1, the third terminal of the circuit protector 5 is connected to the first analog terminal (C1+) of the temperature control unit 21, and the fourth terminal of the circuit protector 5 is connected to the second analog terminal (C1-) of the temperature control unit 21. The current protector can protect against the instantaneous short-circuit current output from the first and second analog terminals of the three-phase power adjuster 1 when a fault occurs, preventing the instantaneous short-circuit current from damaging the temperature control unit 21.
[0043] In one implementation, such as Figure 1 As shown, the current protector can be a first fuse (RU1) and a second fuse (RU2). The first terminal of the first fuse is connected to the first analog terminal (C1+) of the three-phase power regulator 1, and the second terminal of the first fuse is connected to the first analog terminal (C1+) of the temperature control unit 21. The first terminal of the second fuse is connected to the second analog terminal (C1-) of the three-phase power regulator 1, and the second terminal of the first fuse is connected to the second analog terminal (C1-) of the temperature control unit 21. Using fuses to achieve short-circuit protection between the analog terminal of the three-phase power regulator 1 and the temperature control unit 21 can effectively prevent short-circuit current from damaging the temperature control unit 21. Fuses also have the advantage of low cost.
[0044] In one embodiment, the first fuse can be a 25mA fuse; the second fuse can also be a 25mA fuse.
[0045] In one embodiment, indicator lights can be installed on the first and second fuses. The indicator lights can illuminate when the first and second fuses malfunction, indicating that the circuit is faulty and needs to be repaired. This has the advantages of facilitating maintenance and improving maintenance speed.
[0046] In one implementation, such as Figure 1 As shown, the three-phase power adjustment device may further include an intermediate relay 6 (Ka); the first terminal of the intermediate relay 6 is connected to the normally open terminal (NO) of the three-phase power regulator 1, the second terminal of the intermediate relay 6 is connected to the common terminal (COM) of the three-phase power regulator 1; the third terminal of the intermediate relay 6 is connected to the third terminal of the PLC module 3, and the fourth terminal of the intermediate relay 6 is connected to the fourth terminal of the PLC module 3.
[0047] In one implementation, the PLC module 3 controls the start and stop of the intermediate relay 6. This forms circuit isolation, preventing short-circuit current from flowing directly to the PLC module 3, thus protecting the PLC module 3.
[0048] In one implementation, such as Figure 1 As shown, PLC module 3 includes PLC I / O unit 31 and PLC communication unit 32.
[0049] This utility model, by adding a surge protector 4, an intermediate relay 6, and a circuit protector 5 to the three-phase power regulator, can provide accurate and effective protection for devices connected to the three-phase power regulator 1, such as the temperature control unit 21, flow meter 23, butterfly valve 22, and PLC module 3, in the event of a short circuit in the three-phase power regulator 1. This prevents the short-circuit current from damaging the aforementioned devices, reduces the cost of maintenance and spare parts for the three-phase power regulator, and also adds indicator lights to both the surge protector 4 and the circuit protector 5, which can facilitate timely detection of circuit faults, simplify maintenance, and reduce downtime.
[0050] Furthermore, it should be understood that since the various modules are only provided to illustrate the functional units of the device of this utility model, the physical devices corresponding to these modules may be the processor itself, or a part of the processor's software, hardware, or a combination of software and hardware. Therefore, the number of modules shown in the figure is merely illustrative.

Such splitting or combining of specific modules will not cause the technical solution to deviate from the principle of this utility model; therefore, the technical solution after splitting or combining will fall within the protection scope of this utility model.
[0052] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
