DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0024] Referring to Figure 1 , Figure 3 and Figure 4 , the utility model provides an embodiment: a rectification inverter boost's plasma power supply, including power shell 1, the upper portion of the front end of power shell 1 is provided with two display screens 3, display screen 3 can display the working parameter of plasma power supply in real time, such as voltage, current, power, frequency etc., make operating personnel can understand the running state of equipment in time, the lower portion of the front end of power shell 1 is provided with switch 4, the end close to switch 4 of power shell 1 is provided with adjusting knob 8, adjusting knob 8 is electrically connected with frequency converter 19, can adjust the frequency required through adjusting knob 8, the inside of power shell 1 is equipped with temperature sensor, the rear end of power shell 1 is provided with rear shell 10, the surface of the end away from power shell 1 of rear shell 10 is provided with ventilation slot 11 on both sides, the rear end surface middle part of rear shell 10 is provided with cooling fin 15, the surface of the rear shell 10 that cooling fin 15 contacts is coated with heat-conducting silicone grease, the surface of the end close to cooling fin 15 of power shell 1 is fixedly connected with two mounting covers 12, mounting cover 12 is used to protect cooling fan 16, mounting cover 12 is installed cooling fan 16 in the inside, every mounting cover 12 is arranged between a ventilation slot 11 and cooling fin 15, the end away from mounting cover 12 of rear shell 10 is installed with two dustproof plates 14, single dustproof plate 14 should cover a ventilation slot 11 and a mounting cover 12, the inside of power shell 1 is provided with inverter boost assembly.

[0025] Specifically, when the plasma power supply is not working hard, the temperature in the plasma power supply can be dissipated through the heat sink 15 and the two ventilation slots 11. When the temperature exceeds the set threshold, the heat dissipation fan 16 is started to increase the heat dissipation capacity of the power supply. The dustproof plate 14 can prevent dust from entering the interior of the power supply from the ventilation slots 11 and the fan slots. This setting can effectively dissipate the heat of the plasma power supply in time, avoid the temperature affecting the work of the power supply, and reduce the energy consumption for heat dissipation.

[0026] With reference to Figure 1 , Figure 3 and Figure 5 , the inverter boosting assembly includes a rectifier 17 fixedly connected to the inner bottom wall of the power supply shell 1. The interior of the power supply shell 1 is provided with an inverter 18. The right side of the inverter 18 is provided with a frequency converter 19. The front side of the frequency converter 19 is provided with a transformer 20. The transformer 20 adopts a ring transformer. The ring transformer has higher energy conversion efficiency and lower heat generation. The front end of the power supply shell 1 is provided with an electricity connection end 5. The electricity connection end 5 is electrically connected with the rectifier 17. The right side of the electricity connection end 5 is provided with three power transmission ends 6. The power transmission ends 6 are electrically connected with the transformer 20.

[0027] Specifically, the rectifier 17 adopts a conventional three-phase bridge rectifier. Through the rectifier 17, the three-phase 380-volt current of the electricity connection end 5 can be rectified into direct current. Then, through the inverter 18, the direct current is converted into single-phase alternating current. Then, through the frequency converter 19, the current frequency is obtained. Finally, through the transformer 20, the current is converted into three single-phase 800-1000-volt voltage. Thus, the three power transmission ends 6 supply power to external devices. This setting changes the traditional plasma power supply which needs to ensure a 120-degree phase difference between three phases. It does not need to equip each motor with a separate transformer 20. Thus, the power supply cost is greatly reduced. Furthermore, the high temperature rise of the power supply is further reduced.

[0028] With reference to Figure 1 and Figure 2 , the bottom end surface of the power supply shell 1 is fixedly connected with support legs 13 at four corners. The front end edges of the power supply shell 1 are fixedly connected with handles 2 at both sides. The power transmission ends 6 are provided with indicator lights 7 above.

[0029] Specifically, the indicator lights 7 can determine whether the power transmission ends 6 can work normally. The maintenance door 9 is convenient for the maintenance of the interior of the power supply.

[0030] Working principle: first, the three-phase 380V AC power of the power input end 5 is rectified into DC power by the rectifier 17, then is converted into single-phase AC power by the inverter 18, then is converted into the required current frequency by the frequency converter 19, and then is outputted to the three power output ends 6 respectively by the transformer 20 as single-phase 800-1000V power supply; when the power supply has low working intensity, the heat generated by the power supply can be dissipated by the two ventilation grooves 11 and the heat dissipation fins 15; when the temperature of the power supply exceeds a certain threshold, the two heat dissipation fans 16 can be started to enhance the heat dissipation capacity of the power supply.

[0031] Finally, it should be pointed out that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application are described in detail, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included in the scope of the present application.
