Description

Reactive power compensation economize on electricity filter
Technical field
The utility model belongs to distribution control field, particularly relates to a kind of reactive power compensation economize on electricity filter.
Background technology
In electric power system, reactive power is requisite in the electric energy transmitting process, and directly influences the voltage stability of system, is the important indicator of the quality of power supply.The transmission of reactive power makes the electrical network total current increase, and the capacity and the active loss of power factor reduction, equipment increase.Therefore, in order to reduce the transmission of reactive power in network, should realize the power local compensation as much as possible.In the particularly existing industrial and mining enterprises, how based on motor, because motor is an inductive load, to consume the part reactive power to the electrical network electric energy, but the common reactive power governing speed of reactive power compensator in the existing power distribution network is slow, controlled target is single, can only stepped realization reactive power compensation or the uncompensation capacity little, and do not possess idle Continuous Compensation and than the function of large compensation capacity.
Summary of the invention
The utility model is intended to overcome the deficiencies in the prior art, and a kind of reactive power compensation economize on electricity filter is provided.
Reactive power compensation economize on electricity filter of the present utility model is made up of idle compensating control, switch, current transformer, fusing device, A.C. contactor, thermal relay and electric capacity.Described inlet wire connects through idle compensating control, switch, is connected through current transformer, fuse, A.C. contactor, thermal relay and electric capacity respectively again; Wherein, current transformer connects with lightning arrester.
Reactive power compensation of the present utility model economize on electricity filter, reasonable in design, cost is low, efficient is high, energy-saving effect is remarkable.
Description of drawings
Fig. 1 is the structural representation of the utility model reactive power compensation economize on electricity filter.
Embodiment
Reactive power compensation economize on electricity filter of the present utility model is made up of idle compensating control 1, switch 2, current transformer 3, fusing device 4, A.C. contactor 5, thermal relay 6 and electric capacity 7.Described inlet wire connects through idle compensating control 1, switch 2, the output of switch 2 divides two-way to be connected through current transformer 3, fuse 4, A.C. contactor 5, thermal relay 6 and electric capacity 7 respectively, wherein, the output of switch 2 also connects with lightning arrester 8 through current transformer 3.
