Abstract
The utility model belongs to the technical field of power equipment and specially relates to a fire line connecting and disconnecting device of a lead of a strain section. It is characterized in that the fire line connecting and disconnecting device of the lead of the strain section includes a first insulation sleeve, a first lock wrench, a second insulation sleeve, a second lock wrench, a first bolt, a telescopic lead, and a second bolt. Wrench mouth positions of the first lock wrench and the second lock wrench are both provided with lead connecting holes. The first bolt penetrates through the lead connecting hole on one end of the telescopic lead. The lead connecting hole in the first lock wrench fixes the end of the telescopic lead and the first lock wrench. The second bolt penetrates through the lead connecting hole on the other end of the telescopic lead. The lead connecting hole in the second lead connecting hole fixes the other end of the telescopic lead and the second lock wrench. A position below the wrench mouth of the first lock wrench is sleeved with the first insulation sleeve. A position below the wrench mouth of the second lock wrench is sleeved with the second insulation sleeve. The fire line connecting and disconnecting device of the lead of the strain section in the utility model has characteristics of high safety and high efficiency.
Description
Technical field
The utility model belongs to electrical equipment technical field, is specifically related to a kind of device of starting to exchange fire of separating of strain section lead-in wire.
Background technology
Along with constant development of economy, also improve constantly for the requirement of power supply reliability, and distribution network live line work is the effective way that improves power supply reliability.In distribution network live line work, breaking and connecting lead-in wires is modal project, and in the operation of all kinds disconnecting lead-in wire, operation is the most complicated, and dangerous spot is maximum, and it the highest is exactly " strain section lead-in wire separate the operation of starting to exchange fire " that peopleware requires.
The separating of strain section, starting to exchange fire is meant what strain section carried out and chargedly separates the operation of starting to exchange fire; Because the end of a thread of the mains side of strain section and load side does not all have to fix, thus strain section charged separate the operation of starting to exchange fire be always one to the exigent project of operating personnel's technical merit.At present, use the sub-thread aluminum steel to overlap (the end of a thread that aluminum steel twines mains side and load side), lapping time is long, aluminum steel easy fracture in the process of starting to exchange fire; Poor stability, efficient are low.
Summary of the invention
The purpose of the utility model is to provide a kind of device of starting to exchange fire of separating of strain section lead-in wire, and this device has the advantages that fail safe is good, efficient is high.
To achieve these goals; Technical scheme that the utility model adopts is: strain section lead-in wire separate the device of starting to exchange fire, it is characterized in that it comprises first insulating case, first locking pliers, second insulating case, second locking pliers, first bolt, flexible lead, second bolt; The tong chops position of first locking pliers, second locking pliers is equipped with wire connection hole; To a stretch end and first locking pliers of lead of wire connection hole, the wire connection hole on first locking pliers that first bolt passes an end of flexible lead fixed, and will the stretch other end and second locking pliers of lead of wire connection hole, the wire connection hole on second locking pliers that second bolt passes the other end of the lead that stretches fixed; Be with first insulating case below the tong chops position of first locking pliers, be with second insulating case below the tong chops position of second locking pliers.
The beneficial effect of the utility model is: adopt between 2 locking pliers to be communicated with by flexible lead, realized the quick attaching of overlap joint lead, efficient is high; Locking pliers the end of a thread is clamped, and fail safe is good.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the structural representation of locking pliers.
Among the figure: 1-first insulating case, 2-first locking pliers, the end of a thread of 3-mains side, the end of a thread of 4-load side, 5-second insulating case, 6-second locking pliers, 7-first bolt, the 8-lead that stretches, 9-second bolt, 10-wire connection hole.
Embodiment
As shown in Figure 1, strain section lead-in wire separate the device of starting to exchange fire, it comprises first insulating case 1, first locking pliers 2, second insulating case 5, second locking pliers 6, first bolt 7, flexible lead 8, second bolt 9; The tong chops position of first locking pliers 2, second locking pliers 6 (or claiming binding clip) is equipped with wire connection hole 10; To a stretch end and first locking pliers of lead of wire connection hole, the wire connection hole on first locking pliers 2 that first bolt 7 passes an end of flexible lead 8 fixed; Second bolt 9 passes flexible lead, and (interior is annealed copper wire; Insulating barrier is arranged outward; Two ends are connector, and connector is provided with wire connection hole) will the stretch other end and second locking pliers of lead of wire connection hole, the wire connection hole on second locking pliers 6 of 8 the other end fix; Be with second insulating case 5 below being with the tong chops position of first insulating case, 1, the second locking pliers 6 below the tong chops position of first locking pliers 2.
The material of locking pliers is a steel, and resistance is higher, and therefore the tie point with joint and flexible lead has fixed on tong chops position (or claiming binding clip).
Use: separate and start to exchange fire, the tong chops of second locking pliers 6 is clamped the end of a thread 4 of load side, the tong chops of first locking pliers 2 is clamped the end of a thread 3 of mains side, the end of a thread 4 of load side and the end of a thread 3 of mains side are by flexible lead 8 conductings.Break off, only need first locking pliers 2, second locking pliers 6 are taken off from the end of a thread and get final product.
Use through reality, the efficient of separating, starting to exchange fire of strain section improves greatly, and average operating time was reduced to 12 minutes by before 23 minutes; And the situation of wire fracture also is reduced to 0 time in actual use.
