Abstract
The utility model relates to a reactive capacitance power factor compensation device, which is characterized by comprising a power factor controller and a plurality of power capacitors connected with the power factor controller; and the power factor controller generates a plurality of switching values and respectively transmits the switching values to the power capacitors to switch. The reactive capacitance power factor compensation device disclosed by the utility model is simple in structure and is capable of automatically compensating for load power factors.
Description
Technical field
The utility model relates to industrial circle, refers in particular to the Factor Compensate system And to equipment.
Background technology
At industrial circle, the operation of equipment all needs to realize by electric energy.The electrical parameters such as the active power of equipment operation, power factor (PF) all need be controlled within the OK range, otherwise equipment operating efficiency is low, and it is very high that reactive loss tends to, and wastes energy.For this situation, all adopt power factor to compensate, raise the efficiency.What usually adopt is that electric capacity is concentrated switching, and centralized compensation improves electric power, improves grid stability, saves grid net loss and loss on transmission.But mending generally can appear in centralized compensation or few situation of mending.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of power factor compensation device, and it can movable type carry out the local compensation switching one by one as required, excessively benefit or few benefit of having avoided concentrated switching to bring.
For above-mentioned technical problem, the technical scheme that the utility model provides is a kind of idle electric capacity power factor compensation device, it is characterized in that described power factor compensation device comprises power factor controller and several power capacitors that are attached thereto; Described power factor controller produces several switching values and sends respectively described power capacitor to and carry out switching.
Each described power capacitor is connected to form a discharge loop by the A.C. contactor that is attached thereto and the power supply circuits of load respectively, and the switching value that described power factor controller produces sends respectively the break-make that described contactor is controlled described discharge loop to.
Between described contactor and described power supply, be provided with the switch that can cut-off.
Power factor compensation device of the present utility model is simple in structure, can as required, control the switching of power capacitor by power factor controller.When learning according to calculating in the situation that electric capacity of input gets final product, the switching value that sends power factor controller drops into an electric capacity and compensates, when calculating learnt that needs drop into several electric capacity, the switching value of then sending equity dropped into needed electric capacity and compensates.Realized one by one portable capacitor switching, guaranteed that power factor compensation can not crossed to mend or few the benefit.
Description of drawings
Fig. 1 the utility model structural representation.
Embodiment
For technique scheme, now lift a preferred embodiment and be specifically described in conjunction with graphic.Referring to Fig. 1, power supply 1, load 2, power factor controller 3, A.C. contactor 4, power capacitor 5; Wherein.
Power supply 1 is connected to load 2 with load 2 electric energy is provided.It is connected the monitoring power factor with the power supply circuits of electric energy are provided for load 2 power factor controller 3.A.C. contactor 4 is connected with the power supply circuits of power factor controller 3, power capacitor 5, load 2 respectively.Be connected to form charge circuit and discharge loop between the power supply circuits of A.C. contactor 4, power capacitor 5, load 2.A.C. contactor 4 be provided with switch 41 between the power supply circuits of load 2 are connected.When A.C. contactor or power capacitor break down, but closing switch 41 keeps in repair.
Power factor controller 3 detects power factor less than prescribing a time limit under the set point when it, calculate the power capacitor number of required input according to difference, from trend A.C. contactor transmit button amount, make the contact contact of A.C. contactor, the discharge loop of conducting power capacitor compensates power supply circuits; Prescribe a time limit when power factor exceeds on the set point, power factor controller 3 is according to calculated difference, and the transmit button amount breaks away from its contact to exchanging contactor, and power capacitor is broken from electrical network.
Idle electric capacity power factor compensation device of the present utility model, it is simple in structure, can automatically compensate the power-factor of load on the spot.
