Description
Technical field
The utility model relates to a kind of compensation arrangement of electric power system, belongs to the heavy current installation technical field, refers in particular to a kind of dynamic complex reactive power compensator.
Background technology
For transmission line or local power system, when carry equating the active power of number, also with the suitable reactive power of number.If supply power voltage is certain, when the power factor step-down, then electric current increases, and line loss is increased, and reduces the power supply capacity of electric power system, and the quality of supply power voltage, will produce adverse influence to system.Networks at different levels and controller switching equipment all will consume the reactive power of some, wherein the reactive power proportion maximum of power distribution network consumption.The centralized compensation of transformer station mainly is the reactive loss of compensator transformer itself, and the reactive power that reduces the above transmission line transmission of transformer station, thereby reduce the reactive loss of supply network, but it does not reduce the reactive loss of distribution network, and idle still needs that the user needs carries to load by the distribution line below the transformer station.

To achieve these goals, the utility model is realized by following technical scheme:
A kind of dynamic complex reactive power compensator includes controller, switch with knifeshaped fuse, measurement instrument transformer, lightning arrester, fuse and compensation Shunt Capacitor Unit; Inlet wire is divided into two branch roads through switch with knifeshaped fuse with after measuring instrument transformer, and a branch road connects lightning arrester, and another branch road connects the compensation Shunt Capacitor Unit by air switch; First parallel branch of compensation Shunt Capacitor Unit includes the fuse of serial connection, mends electric capacity and indicator light admittedly, and second parallel branch includes fuse, dynamic complex switch and the capacitor group of serial connection.
Further, the described dynamic complex switch controllable silicon and the magnetic latching relay that include and connect.
Further, also include temperature control system, described temperature control system includes fuse, thermostat and the fan of serial connection.
Further, described controller is installed on operating board.
The utility model compared with prior art, its beneficial effect is: the utility model is a kind of most important forms of power system reactive power dispersion compensation, it to the power factor, the ability of giving full play to electricity supply and use equipment that improve network, adjust voltage, reduce network loss, and improve power supply quality and all will have great importance.
