Abstract
The utility model discloses a kind of device for checking cable connection, which includes：Transformer connects the control switch of transformer inputs, connects the ammeter of transformer output terminal,, will be by the piece-root grafting line in check cable and the bonding line short circuit of the cable in load side during check；In mains side, the second output lead of device described in the utility model and cable shield ground wire are connected, by any one piece-root grafting line in the first output lead short time connecting cable of described device；Ammeter is observed, when the beat of pointer of ammeter is big, wiring and the wiring of load side short circuit bonding line that the first output lead of described device is connected belong to same root wiring；Thus the first piece-root grafting line is checked out.The utility model need not remove the electrical equipment of cable load side when checking cable connection, reduce labor intensity, improve work efficiency, shorten the idle time of equipment.
Description
Technical field
The utility model belongs to power supply technique field more particularly to a kind of device for checking cable connection.
Background technology
In electric power system, when the maintenance of progress cable and troubleshooting, it is necessary to which cable is disconnected from switchgear, overhaul
When end is resumed operation, to ensure the correctness of wiring, and need to confirm the phase sequence of the multiple conducting wires in cable, 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, work efficiency is low, simultaneously because the time growth that electrical equipment is out of service, shadow is caused to normal production
It rings.
Utility model content
Above-mentioned in order to solve the problems, such as, the utility model proposes a kind of devices for checking cable connection so that in school
The electrical equipment of cable load side need not be removed during nuclear cables wiring, reduces field labor intensity, improve work efficiency,
Shorten the idle time of equipment.
To achieve these goals, the utility model uses following scheme, including：
Transformer, the first terminals connection control switch of the transformer inputs, the other end of control switch connect
The first input lead is connect, the second terminals of the transformer inputs connect the second input lead；The transformer output terminal
The first terminals connection ammeter, the other end of the ammeter connects the first output lead, the of the transformer output terminal
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, control switch, ammeter are fixedly mounted on a mounting board.
It, will be by the bonding line of the piece-root grafting line in check cable and the cable with shorting stub in load side during check
Short circuit；In mains side, the second output lead of device described in the utility model and cable shield ground wire are connected, by this practicality
Any one piece-root grafting line in first output lead short time connecting cable of new described device；Ammeter is observed, works as ammeter
The beat of pointer it is big when, the wiring that the first output lead of device described in the utility model is connected is connected bonding with load side
The wiring of line belongs to same root wiring；Thus the first piece-root grafting line is checked out.
And so on, the wiring in remaining cable is checked out one by one.
The utility model proposes a kind of check cable connection device, need not remove cable when checking cable connection
The electrical equipment of load side reduces field labor intensity, improves work efficiency, shortens the idle time of equipment.
Description of the drawings
Fig. 1 is the schematic diagram that the device of the utility model and the device check cable connection.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings, so that those skilled in the art can be more
Add and be apparent from, as shown in Figure 1, the utility model includes：
Transformer 2,2 input terminal of transformer the first terminals connection control switch 1, the control switch 1 it is another
The first input lead of end connection, the second terminals of 2 input terminal of transformer connect the second input lead；The transformer 2
The first terminals connection ammeter 3 of output terminal, the other end of the ammeter 3 connect the first output lead, and the transformer 1 is defeated
Second terminals of outlet 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, control switch 1, ammeter 3 are fixedly mounted on installing plate 11.
During check, in the load side of supply transformer 10,10 wire connection terminal 9 of supply transformer will be connected to shorting stub 8
On 7 short circuit of bonding line by the piece-root grafting line in check cable and the cable；In the mains side of power distribution cabinet 4, by this reality
It is connected with the second output lead of new described device with cable shield ground wire 6, by the first of device described in the utility model
Any one piece-root grafting line of several wiring 5 in output lead short time connecting cable；Ammeter 3 is observed, when the pointer of ammeter 3 is put
When dynamic big, wiring and the wiring of load side short circuit bonding line that the first output lead of device described in the utility model is connected
Belong to same root wiring；Thus the first piece-root grafting line is checked out.
And so on, the wiring in remaining cable is checked out one by one.
The utility model proposes a kind of check cable connection device, need not remove cable when checking cable connection
The electrical equipment of load side reduces field labor intensity, improves work efficiency, shortens the idle time of equipment.
