A circle of limiting plates 5 are provided along the edge line of the upper top surface of the cabinet 1. When stacked, the lower bottom surface can just be placed in a circle of limiting plates 5. When installing the cabinet 1 and the control box 3, the limiting plates 5 play a role of pre-positioning. The nuts 6 are threadedly connected with the positioning pins 2. The control box 3 is fixedly installed on the top of the stacked cabinets 1. Two No. 2 positioning holes 12 are provided on the lower bottom surface of the control box 3. The No. 2 positioning holes 12 are respectively located at the diagonal positions of the lower bottom surface of the control box 3, and the No. 2 positioning holes 12 correspond to the positioning pins 2. The lower bottom surface of the control box 3 is the same size as the lower bottom surface of the cabinet 1. The lower bottom surface of one cabinet 1 is placed on the upper top surface of another cabinet 1. At this time, the fixing plate 5 of the cabinet 1 at the bottom The positioning pin 2 is inserted into the positioning hole 4 of the upper cabinet 1, and the nut 6 is threadedly connected with the positioning pin 2. At this time, the two cabinets 1 are fixed, and the No. 2 positioning hole 12 at the bottom of the control box 3 corresponds to the positioning pin 2 on the top of the cabinet 1. The control box 3 is placed on the top of the cabinet 1 and the positioning pin 2 is inserted into the control box 3. The control box 3 is fixed to the top of the cabinet 1 through the nut 6. When it is necessary to add a cabinet 1, the line is removed and the nut 6 of the top cabinet 1 is unscrewed, and then a cabinet 1 is placed between the first and second cabinets 1 and the nut 6 is tightened to complete the increase of the cabinet 1. When it is necessary to reduce the cabinet 1, the nuts 6 of the upper and lower positioning pins 2 of one layer of the cabinet 1 are removed, the cabinet 1 can be moved out, and then the remaining cabinets 1 can be reconnected. The cooling fans 7 on both sides of the cabinet 1 blow air inward on one side and exhaust air outward on the other side. The cooling fans 7 on both sides strengthen the exchange of air in the cabinet 1 with the external air to quickly take away heat. There are multiple groups of capacitors 8 inside the cabinet 1, and the lines of multiple cabinets 1 above and below are connected through the connecting port 9.
