Embodiment
Embodiment mono-
The present embodiment oppose electricity-stealing sampling thief as shown in Figures 1 to 6, comprise insulation plastic cement involutory upper module 1 and the lower module 2 made.Upper module 1 is embedded with the ∩ shape iron core 1-1 being coated by plastic cement and the opening down upper skeleton 1-2 that ∩ shape iron core 1-1 is formed to semi-surrounding, and lower module 2 is embedded with the ∪ shape iron core 2-1 being coated by plastic cement and the lower skeleton 2-2 that ∪ shape iron core 2-1 is formed to semi-surrounding.For the ease of involutory time location, and make the involutory contact of iron core more reliable by forming step involutory surface, the through wires hole both sides of the lower surface of upper module 1 and lower module 2 upper surfaces form respectively pan 1-4 and the boss 2-4 that shape matches, and the apparent surface of ∩ shape iron core 1-1 and ∪ shape iron core 2-1 flushes with the bottom surface of pan 1-4 and the end face of boss 2-4 respectively.Lower skeleton 2-2 is as described in Fig. 6, Fig. 7, by upper opening upper prong and lower opening lower prong down upward, formed, the lower prong of below is for being installed with the output terminal 3 containing current sampling terminal and voltage sampling terminal 3-1, and the lower end of output terminal 3 is overhanging link.The both sides of ∪ shape iron core 2-1 are set with the inductive coil 4 that output terminal is connected to current sampling terminal.Relative upper horizontal tail 1-3 and lower horizontal tail 2-3 are extended respectively in the both sides of upper skeleton 1-2 and lower skeleton 2-2, after involutory, by the clamp-screw 5 through lower horizontal tail 2-3, be screwed in the threaded hole of upper horizontal tail 1-3, after upper and lower skeleton 1-2,2-2 are fixedly connected with, the involutory closed-loop shaped iron core that is shaped as center through wires hole 6 of ∩ shape iron core 1-1 and ∪ shape iron core 2-1.Upper module 1 and lower module 2 two ends extend axially out outstanding position 1-5,2-5 along through wires hole 6 respectively, pass vertical with it end skeleton 2-6 in the lower prong of lower skeleton 2-2.The outstanding position 2-5 of lower module 2 both sides respectively by under be equipped with upward to screw in the power taking at skeleton 2-6 two ends, the end and press nibbed screw 7, and power taking presses the inner of nibbed screw 7 to stretch into through wires hole 6, by wire, is connected to voltage sampling end.
During use, as shown in Figure 8, upper module 1 and lower module 2 is involutory in the electric wire place 8 of need monitoring, tightening power taking presses nibbed screw that its tip is electrically contacted through the outer and inner wire of electric wire again, by the signal wire 9 being connected with the overhanging link of output terminal, be connected to the supervisory instrument 11 of opposing electricity-stealing being fixed on electric pole 10, electric current, voltage sampling Monitoring Data can be transferred to analysis platform analysis, when electric current difference is greater than 20% or voltage difference while being greater than 20%, analysis platform automatic alarm, thereby find in time stealing electricity phenomenon, to take appropriate measures.
