Information
For the traditional reactive power capacitor compensation cabinet, the capacitor switching switch is connected to the controller of the reactive power capacitor compensation cabinet through the secondary line. The controller of the reactive power capacitor compensation cabinet is installed on the panel. The connection distance is too long, so the loss in in the secondary line is very large. In addition, this also leads to winding of the wire harnesses, which does not looks beautiful and also costs a lot of money.
Today, let the writer to have a talk with you on those things which are related the secondary lines!
1) At the early design stage of the reactive power capacitor compensation cabinet. At the beginning of the design, it is necessary to combine with the control principle and electrical principle of the whole reactive power capacitor compensation cabinet system. The input and output of the switching switch should be considered comprehensively and a schematic diagram of the secondary line should be drawn. In considering the switching input, the output line and the capacitor switching indication line, it takes a lot of time to design and make arrangement for the layout of the orientations of the lines. This may result in a great amount of time being wasted.
2) At the time when the plant has been put into production. The layout of the secondary line can seriously affect the progress of the production and the assembly. It takes time to print the electrical labels on the cable, measure the cable length, cut and press the cables, wire connect the cables. In case that several groups of cables have been wound together, it is easy to got confused, which may increase the difficulty of production to a large extent. The experiences in the production have proven one fact, i.e. the waste caused by cutting of the secondary cables may accounts for 1/3 of the cable volume which has been purchased. This may directly affect the purchasing cost, increase the losses, and lead to a series of problems, such as the prolongation of the production cycle and so on.
3) At the time when carrying out the commissioning before being dispatched from the factory. The winding of the secondary cables is complicated, the difficulty in carrying out the debugging will increase. It is necessary to check and make measurements of the cables in turn according to the secondary schematic diagram. If there is not any problem in the process of production, the debugging process can be completed quickly. In case that there is any problem, it takes at least half an hour to carry out the troubleshooting. This will greatly increases the time cost, seriously affect the production efficiency. In addition, as a point where accidents tend to occur, this will directly affect the user's use in the future.
In the design and production process of the reactive power capacitor compensation cabinet, the existence of secondary cable seriously affects the material cost, the time cost and even the labor cost. This has become the biggest problem that puzzles the manufacturers!
In view of the difficult problem related to the secondary cables, DELITER has set up a special work group, which is led by the general manager. This work group has combined the experience in the R&D and production and developed a new type of reactive power capacitor compensation cabinet - the closed type vertical branch bus bar reactive power capacitor compensation cabinet.
The new type reactive power capacitor compensation cabinet adopts the structure in which the bus bars are installed top-down in the vertical direction and the primary cables have been replaced. The intelligent capacitor modules are placed in a symmetrical way in the front and rear of the reactive power capacitor compensation cabinet. Through the transverse sub mother bar and the vertical bus bar, a closed structure with the vertical branch bus bars is formed, which increases the electrical safety and reliability of the reactive power capacitor compensation cabinet!
The intelligent capacitor module adopts the RS485 communication device which has been developed by the company. Only one network wire is needed to realize the new type of control which integrates the functions of control, transmission and measurement. As a result, the secondary cables have been completely replaced, and the efficiency of production and assembly has been doubled.
The controller of the reactive power capacitor compensation cabinet adopts the method in whichthe main control and the display are separated. Synchronization between the indication and the control has been realized in the complete sense by the means of the network line. The use of the secondary cable has been totally eliminated. In addition, the capacitor switching indications have become refined and analyzed. The software design is integrated into the controller. The running state of the capacitors can be observed through the display screen of the controller.
The emerging of the closed type vertical branch bus bar reactive power capacitor compensation cabinet has really solved the huge problem related to the secondary cables!
