The things about reactive power compensation secondary line!

For the traditional reactive power compensation device, the capacitor cutting switch is connected to the compensation controller through the secondary line, and the controller is installed on the panel, the connection distance is too long, and the secondary line loss is large, resulting in the wire harness winding, which is not beautiful and consumes financial resources.
Today, the editor will talk to you about the secondary line!
1), reactive power compensation system design begins. At the beginning of the design, it is necessary to combine the control principle and electrical principle of the entire cabinet system, comprehensively consider the input of the cutting switch, and draw the secondary schematic diagram at the output. Considering the cutting of input, output, and capacitor cutting indicator lines, it takes a lot of time to conceive and lay out the direction of the line, resulting in a lot of wasted time.
2), equipment production. The layout of the secondary line seriously affects the progress of production and assembly. It takes time to print cable electrical labels, measure cable length, cut, crimp, and wire. Multiple sets of cables are entangled together, which is easy to be confused and greatly increases the difficulty of production. Production experience proves that the waste caused by secondary cable cutting accounts for one-third of the cable purchase volume, which directly affects the procurement cost, increases losses and prolongs the production cycle.
3) When factory debugging. The winding of secondary cables is complex, and the difficulty of debugging increases. It needs to be queried and measured sequentially according to the secondary schematic. There are no problems in the production process and the commissioning process can be completed quickly. Once there is a problem, it takes at least half an hour to investigate the problem, which greatly increases the time cost and seriously affects the production efficiency. As a prone point of accidents, it directly affects the user's future use.
In the design and production process of reactive power compensation devices, the existence of secondary cables seriously affects material costs, time costs and even labor costs, becoming the biggest problem for manufacturers!
The new capacitor cabinet uses a vertical vertical female top-down structure instead of cables. The intelligent capacitor module is placed symmetrically front and back, and is connected with the vertical busbar through the horizontal busbar to form a closed vertical branch busbar structure, improving the electrical safety and durability of the equipment!
The intelligent capacitor module adopts the self-developed RS485 communication device, which only needs a network cable to realize a new control integrating control, transmission and measurement, completely replacing the secondary cable and improving production and assembly efficiency.
The reactive power compensation controller adopts the separation of the control body and the display, realizes the display and control synchronization through the network cable, completely eliminates the use of secondary cables, refines the capacitor cutting instructions, analysis and software design, and observes the operating status of the capacitor through the controller display page.
The launch of the closed vertical branch busbar capacitor cabinet really solves the huge problem of the secondary cable problem!
