To achieve these goals, the utility model employs following technical scheme：
A kind of distribution low-voltage circuit livewire work bypath system, mainly by insulation box, the low voltage knife switch with arc-extinguish chamber and
Flexible multiply copper cable is formed；Three low voltage knife switchs with arc-extinguish chamber have been fixedly mounted inside insulation box, and have insulated
The left and right sides panel of casing is provided with the through hole for being used for the disengaging of flexible multiply copper cable；Walking is provided with the bottom of insulation box
Wheel；The both ends of the described low voltage knife switch with arc-extinguish chamber are respectively fixedly connected one end of flexible multiply copper cable, flexible more
Voltage circuit of the other end of stock copper cable through through hole in upkeep operation with outside is connected.
It is furnished with the three-phase low-voltage disconnecting link of soft stock copper cable in the utility model, first grasps at copper cable two with insulation during use
Low pressure gap bridge disconnection fault point both ends are connected on as bar, then low voltage knife switch is closed, sets up temporary current loop, you can recovery is sent
Electricity；After broken line repairing is good, the end cable of device two is removed from circuit.Interim electricity is set up in fault point bypass in parallel
Road is flowed back to, circuit can be made to restore electricity immediately；Meanwhile shunting is played a part of in bypass in parallel, when can reduce docking at break point
Caused electric arc.
Further illustrate, the low voltage knife switch with arc-extinguish chamber mainly by base, two silicon rubber insulator pillars and
Knife switch on silicon rubber insulator pillar is formed；Knife switch include moving contact, static contact, two shoe brake knife plates,
Draw ring and compression spring, an arc-extinguish chamber is provided with moving contact and plug-in strip plate junction；If the arc-extinguish chamber mainly by insulation board and
Dry block U-shaped stainless steel substrates are formed；Described insulation board includes insulated left side plate, side insulation right plate and rear side insulation board；Described
Insulated left side plate, side insulation right plate are respectively equipped with mounting hole；Described U-shaped stainless steel substrates are fixedly mounted on left side by mounting hole
Between insulation board and side insulation right plate.
Further illustrate, described insulation box uses thickness to be formed for 8mm~10mm transparent insulation plate.Such as white thoroughly
Bright hard plastic board etc..Using thicker insulation board, casing is not easy to be not damaged by, and can effectively protect the low voltage knife switch of inside；
Using transparent insulation board, in operation, can externally visibly internal low-voltage disconnecting link working condition, have no-spark or electric arc
Produce etc..
In the utility model, the construction of low voltage knife switch is mainly using low-pressure fusing disconnecting switch in the market（One
Connection three can be with）Construction, be prior art, therefore do not described in utility model content.
The beneficial effects of the utility model：
Simple in construction, small volume, it is convenient for carrying, securely and reliably.When rushing to repair low-voltage circuit disconnection fault, do not have to not only stop
Electricity, without moving back load, and by this system make, because the user that intercoil connection blows power failure has electricity at once, to break down
Restored electricity afterwards with most fast speed, moreover it is possible to the carry out livewire work of repair personnel's safety is fixed a breakdown.
