The preferred embodiment of the utility model is illustrated below in conjunction with attached drawing, it should be understood that described herein excellent It selects embodiment to be only used for describing and explaining the present invention, is not used to limit the utility model.

Embodiment：As shown in Figs. 1-3, the utility model provides a kind of stealing protector, including automatically controlled 1 He of box body of No.1 No. two automatically controlled box bodies 4, automatically controlled 1 side of box body of No.1 are equipped with No.1 cabinet door 2, and 2 side of the cabinet door is equipped with touch screen 3,4 side of No. two automatically controlled box bodies is equipped with No. two cabinet doors 5, and the automatically controlled box body of the No.1 1 is internally provided with No.1 electric-controlled plate 6,6 side of No.1 electric-controlled plate is equipped with controller 7, and 7 lower section of the controller is equipped with No.1 interface end 8, the No.1 interface End 8 is internally provided with the ports No.1 R1 9, and 9 side of the ports the No.1 R1 is equipped with the ports No.1 S1 10, the ports the No.1 S1 10 1 Side is equipped with No.1 t1 port 11, and 11 side of No.1 t1 port is equipped with the ports No.1 N1 12,12 side of the ports the No.1 N1 Equipped with the ports R2 13,13 side of the ports R2 is equipped with the ports S2 14, and 14 side of the ports S2 is equipped with the ports T2 15, the T2 15 side of port is equipped with the ports N2 16, and No. two automatically controlled box bodies 4 are internally provided with No. two electric-controlled plates 17,27 and of A.C. contactor No. two interface ends 18, and A.C. contactor 27 is between No. two electric-controlled plates 17 and No. two interface ends 18, No. two interface ends 18 sides are equipped with the ports R 19, and 19 side of the ports R is equipped with the ports S 20, and 20 side of the ports S is equipped with T-port 21, the T 21 side of port is equipped with N-port 22, and 22 side of the N-port is equipped with No. two ports R1 23, and 23 side of No. two ports R1 is set There are No. two ports S1 24,24 side of No. two ports S1 to be equipped with No. two t1 ports 25,25 side of No. two t1 ports is equipped with No. two ports N1 26.

In order to make this kind of stealing protector, easy to use, work efficiency is high, the automatically controlled box body 1 of No.1 and No. two electricity Control box body 4 is electrical connected.The ports the No.1 R1 9, the ports No.1 S1 10, No.1 t1 port 11, the ports No.1 N1 12, the ends R2 It is fixedly connected, and is respectively positioned on inside No.1 interface end 8 between mouth 13, the ports S2 14, the ports T2 15 and the ports N2 16.The ends R Mouth 19, the ports S 20, T-port 21, the ports R1 23, two of N-port 22, two t1 port 25 of the ports S1 24, two and No. two ends N1 It is fixedly connected, and is respectively positioned on inside No. two interface ends 18 between mouth 26.

When the utility model is used, three-phase and four-line to be connected to the ports R inside No. two automatically controlled box bodies 4 from transformer 19, the ports S 20, T-port 21 and N-port 22；Then by the ends S1 of No. two ports R1 23, two inside No. two automatically controlled box bodies 4 Mouthful 24, No. two t1 ports 25 and No. two ports N1 26 be connected to the ports No.1 R1 9 of the automatically controlled box body of No.1 1, the ports No.1 S1 10, No.1 t1 port 11 and the ports No.1 N1 12；The ports R2 13, the ports S2 14, the ports T2 15 inside the automatically controlled box body of No.1 1 It is connected to base station power supply with the ports N2 16, completes whole installation with this, base station end when system operation passes through No.1 electric cabinet electricity Pressure sampling R, S, the effective current (A) and effective voltage (V) of T three-phases are to obtain real power（W）, transformer terminal passes through No. two The effective current (A) and effective voltage (V) of electric cabinet voltage sample R, S, T three-phase are to obtain real power（W）, it is assumed that three-phase electricity R phases, electric current all be 5A, voltage proximal end be 220V, distally for for 230V circuits partial pressure be 10V.Checking proximal end power is 1100W, it is 1150W to check distal power, and 50 watts of difference is line loss.R phases show that " R phases are normal " illustrates nothing in circuit Abnormal electricity consumption.The S circuitry phases of three-phase electricity are identical as R circuitry phase operating conditions, with display " S phases are normal ".The T-phase of three-phase electricity, it is false If electric current proximal end is 5A circuits, distal end is the abnormal electricity consumption electric current for having 1.5A among 6.5A circuits.Voltage proximal end is 220V, distal end It is 10V to be divided for 230V circuits.So it is 1100W to check proximal end power, it is 1495W, difference 395 to check distal power Watt has the line loss exception electricity consumption 345W of 50W, so T-phase shows " T-phase power stealing ", proximal end No.1 electric cabinet, the electricity of sampling Pressure and current-mode analog quantity voltage, it is proportional relationship greatly to be then converted to digital quantity and the difference of actual Current Voltage very.Institute To need through ratio setting come correcting current ampere（A）It is corresponding with voltage volt.Power is multiplying for actual current and voltage Product is so ratio setting is invalid.This page only sets proximal end（Base station end）Parameter can be set per Phase Proportion, per phase current, voltage, It is the instantaneous value invigilated that power, which can not be set,.The difference that R phase distal powers subtract R phases proximal end power disconnects threshold values more than R phases（It can With setting）, prompt " R phases are sneaked current ".Since line loss and engineering difference actual power difference change in a certain range so needing Setting.Detect which is mutually sneaked current, we will consider that abnormal or interference and data are repeatedly proofreaded, and prevent false triggering from turning off electricity Source, setting delay disconnect.Need there is power stealing just to turn off corresponding power supply always in setting reality.By setting actually detected arrive Really there is power stealing, just disconnect corresponding phase power supply, but needs cannot be disconnected always and connected from new, turn-off time is exactly power stealing It disconnects corresponding power supply and starts timing until setting time is reached from new connection to system power supply.Distally No. two electric cabinets, sampling Voltage and current analog quantity voltage, be then converted to digital quantity and actual Current Voltage difference very greatly only direct proportion close System.So needing through ratio setting come correcting current ampere（A）It is corresponding with voltage volt.Power is actual current and voltage Product so ratio setting is invalid.This page only sets distal end（Transformer terminal）Parameter.It can be set per Phase Proportion, per mutually electricity Stream, voltage, it is the instantaneous value invigilated that power, which can not be set,.Threshold values is disconnected, delay is disconnected to be set as with turn-off time and proximal end Same value and then changes distally setting proximal end, and proximal end sets distal end also and then corresponding variation.

Finally it should be noted that：The above descriptions are merely preferred embodiments of the present invention, is not limited to this Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art For, it still can be with technical scheme described in the above embodiments is modified, or to which part technical characteristic Carry out equivalent replacement.Within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on, It should be included within the scope of protection of this utility model.
