Description
Technical field
The invention belongs to power supply technique field, more particularly to a kind of apparatus and method for checking cable connection.
Background technology
In electric power system, when carrying out cable maintenance and troubleshooting, it is necessary to which cable is broken from switch cubicle, overhaul
When end is resumed operation, to ensure the correctness of wiring, need to confirm the phase sequence of the multiple conducting wires in cable again, to prevent
Only interconnection causes short circuit accident, and the confirmation of this phase sequence generally requires to remove electrical equipment, and this confirmation method causes existing
Field longevity of service, operating efficiency is low, simultaneously because the time growth that electrical equipment is out of service, shadow is caused to normal production
Ring.
The content of the invention
In order to solve above-mentioned problem, the present invention proposes a kind of apparatus and method for checking cable connection so that
The electrical equipment of cable load side need not be removed when checking cable connection, reduces field labor intensity, improves work effect
Rate, the idle time for shortening equipment.
To achieve these goals, the device as the present invention, including：
Transformer, the first terminals connection controlling switch of the transformer inputs, the other end of the controlling switch connect
The first input lead is connect, the second terminals of the transformer inputs connect the second input lead；The transformer output end
The first terminals connection ammeter, the other end of the ammeter connects the first output lead, the of the transformer output end
Two terminals connect the second output lead.
The input voltage of the transformer is alternating current 220V, and the output voltage of the transformer is exchange 6V.
The transformer, controlling switch, ammeter are fixedly mounted on a mounting board.
As the method for the present invention, comprise the following steps：
In the load side of supply transformer, with shorting stub by be connected on transformer connecting terminal by check cable
The bonding line short circuit of one piece-root grafting line and the cable；
In the mains side of power distribution cabinet, the second output lead of device of the present invention and cable shield ground wire are connected,
By any one piece-root grafting line of some wiring in the first output lead short time connecting cable of device of the present invention；
Observe ammeter, when the beat of pointer of ammeter is big, what the output lead of device first of the present invention was connected
Wiring and the wiring of load side short circuit bonding line belong to same root wiring；Thus the first piece-root grafting line is checked out.
By that analogy, the wiring in remaining cable is checked out one by one.
A kind of apparatus and method for checking cable connection proposed by the present invention, electricity need not be removed when checking cable connection
The electrical equipment of cable load side, reduce field labor intensity, improve operating efficiency, shorten the idle time of equipment.
Brief description of the drawings
Fig. 1 is the schematic diagram that the device of the present invention and the device check cable connection.
Embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings, so that those skilled in the art can be more clear
The understanding of Chu, as shown in figure 1, as the inventive system comprises：
Transformer 2, the input of transformer 2 the first terminals connection controlling switch 1, the controlling switch 1 it is another
The first input lead of end connection, the second terminals of the input of transformer 2 connect the second input lead；The transformer 2
The first terminals connection ammeter 3 of output end, the other end of the ammeter 3 connect the first output lead, and the transformer 2 is defeated
The second terminals for going out end connect the second output lead.
The input voltage of the transformer 2 is alternating current 220V, and the output voltage of the transformer 2 is exchange 6V.
The transformer 2, controlling switch 1, ammeter 3 are fixedly mounted on installing plate 11.
As the check method of the present invention, comprise the following steps：
In the load side of supply transformer 10, being checked on the binding post 9 of transformer 10 will be connected to shorting stub 8
The short circuit of bonding line 7 of a piece-root grafting line and the cable in cable；
In the mains side of power distribution cabinet 4, the second output lead of device of the present invention and cable shield ground wire 6 are connected
Connect, by any one piece-root grafting line of some wiring 5 in the first output lead short time connecting cable of device of the present invention；
Ammeter 3 is observed, when the beat of pointer of ammeter 3 is big, the output lead of device first of the present invention is connected
The wiring of wiring and load side short circuit bonding line 7 belong to same root wiring；Thus the first piece-root grafting line is checked out.
By that analogy, the wiring in remaining cable is checked out one by one.
A kind of apparatus and method for checking cable connection proposed by the present invention, electricity need not be removed when checking cable connection
The electrical equipment of cable load side, reduce field labor intensity, improve operating efficiency, shorten the idle time of equipment.
