Abstract
The utility model discloses an anti-theft device for a construction cable. The anti-theft device comprises a power distribution box; and a fuse isolating switch, a 220V leakage circuit breaker, a 380V leakage circuit breaker, an alternating current (AC) contactor, a 220V signal lamp, a 380V signal lamp and a null line connecting plate are arranged in the power distribution box, wherein the leading-out terminal of the fuse isolating switch is respectively connected with the 220V leakage circuit breaker and the 380V leakage circuit breaker, both the 220V leakage circuit breaker and the 380V leakage circuit breaker are connected with the AC contactor, the 220V signal lamp and the 380V signal lamp are respectively connected onto the AC contactor, and the signal lamps respectively correspond to the leakage circuit breakers. The anti-theft device is additionally provided with a power supply, wherein the live line of the power supply is connected with the fuse isolating switch, and the null line of the power supply is connected with the 220V leakage circuit breaker through the null line connecting plate. According to the anti-theft device for the construction cable, the structure that the fuse isolating switch, the leakage circuit breakers and the AC contactor are arranged in the power distribution box is adopted, and corresponding signal lamps are used for displaying the working situation of a circuit, so that the open circuit of the phase A, phase B and phase C of the cable can be monitored after the anti-theft device is connected into a shunt circuit of the cable, thus the aim of monitoring a whole power consuming circuit of the shunt circuit is realized.
Description
Technical field
The utility model relates to a kind of electrical technology field, particularly a kind of construction cable theft-prevention device.
Background technology
At present, the construction cable be unit in charge of construction in work progress, one of common tool.In use often because cable is long, for a long time make cable impaired, cable leakage, on fire, problem makes people such as ground connection is undesirable be easy to contact the generation that causes a series of safety problems.And because the material value of construction cable itself is higher; Very easily cause the construction cable stolen; Not only cause the direct economic loss of bringing because of cable itself, also can cause running device, cause harmful effect to construction unit because of sudden power causes safety problem and the delay of duration.This type of problem does not all obtain fine must the processing always.
Summary of the invention
The utility model technical matters to be solved is: a kind of construction cable theft-prevention device is provided, and whether its cable of in time finding to construct breaks off, thereby finds whether the construction cable connectivity problem or stolen occurs, to overcome the deficiency of prior art.
The utility model be achieved in that construction cable theft-prevention device, comprise panel box, in panel box, be provided with the fusing disconnector, 220V RCCB, 380V RCCB, A.C. contactor, 220V signal lamp, 380V signal lamp and connecting to neutral board; The leading-out terminal of fusing disconnector connects 220V RCCB and 380V RCCB respectively; The equal incoming transport contactor of 220V RCCB and 380V RCCB; On A.C. contactor, connect 220V signal lamp and 380V signal lamp respectively, signal lamp is corresponding with RCCB respectively; Other is provided with power supply, and the single line of power supply inserts the fusing disconnector, and the single line in addition of power supply inserts the 220V RCCB through the connecting to neutral board.
In panel box, also be provided with the ground connection board.So just can the ground wire of the secondary case on the line terminal be drawn, be connected, thereby avoid the secondary case ground connection operation on the floor to be difficult for the problem of carrying out with the ground connection board as in the panel box.
On A.C. contactor, be provided with emergency stop switch.Overhaul at the replacing signal lamp and the inspection of line with convenient.
Owing to adopted technique scheme; Compared with prior art; The utility model is employed in the structure that fusing disconnector, RCCB and A.C. contactor is set in the panel box, and the working condition of utilizing corresponding signal lamp to come display circuit is behind the branch circuit that inserts cable; Can realize opening circuit of monitoring cable A, B, C three-phase, realize the purpose of the whole shunt of monitoring with electric line.The utility model is simple in structure, can in time observe the open circuit conditions of construction cable, thereby can report emergency case fast or find that stolen situation takes place the construction cable, and result of use is very good.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model;
Accompanying drawing 2 is the circuit diagram of the utility model.
Embodiment
The embodiment of the utility model: the structure of construction cable theft-prevention device is as shown in Figure 1; Comprise panel box 1, in panel box 1, be provided with fusing disconnector 2,220V RCCB 3; 380V RCCB 4; A.C. contactor 5,220V signal lamp 6,380V signal lamp 7, connecting to neutral board 8 and ground connection board 9; The leading-out terminal of fusing disconnector 2 connects 220V RCCB 3 and 380V RCCB 4 respectively; 220V RCCB 3 and 380V RCCB 4 equal incoming transport contactors 5; On A.C. contactor 5, connect 220V signal lamp 6 and 380V signal lamp 7 respectively, signal lamp is corresponding with RCCB respectively; Other is provided with power supply 10, and the single line of power supply 10 inserts fusing disconnector 2, and the single line in addition of power supply 10 inserts 220V RCCB 3 through connecting to neutral board 8; And on A.C. contactor 5, be provided with emergency stop switch
In use, panel box 1 is brushed redness, and be installed in the position of being convenient to operator on duty's observation in entrance guard's duty room; Secondary panel box 11 outgoing cables from the line terminal, the cable of drawing is divided into A, B, C three-phase, and B, C two to inserting fusing disconnector 2, are inserted ground connection board 9 (the ground angle steel is buried in employing) with A mutually; When cable was in proper working order, 380V signal lamp 7 was bright, in case a situation about opening circuit mutually appears, the normally closed disconnection of the contact point of A.C. contactor 5, and it is bright that 380V signal lamp 7 extinguishes 220V signal lamp 6, and normal switching of ac contactor contact closed; When the generation three-phase opened circuit, 220V signal lamp 6 and 3380V signal lamp 7 extinguished entirely.The operator on duty can in time handle according to the situation of signal lamp accordingly.
