It is more dispersed, due under without ammeter state, and concentrate under ammeter state, easily cause point family electricity from point family bar to user
Cable is long, installation node is excessive, cable sheath aging after long-term use, easily causes the potential safety hazards such as electric leakage.
According to the industry requirement of current power system, it is necessary to carry out a point family ammeter installation.It is difference by the way of at present
From 0.4KV three-phase main line bar, each phase will be drained and maked somebody a mere figurehead by branching pole, be sent into user.Therefore, family cable is divided
Excessively concentrate, repair or change a wherein point of family cable, it is necessary to break multiple users even larger range of user power utilization.
Therefore, according to foregoing situation, it can be determined that go out, existing wiring and separated time mode, due to no significantly disconnected
Prescribe, it is inconvenient to result in maintenance.According to existing wiring and separated time mode, it is necessary to disconnect from three-phase main line bar to nearest
The live wire and zero line divided between the bar of family, can be repaired and be changed a point operation for family line.
Utility model content
The utility model is in order to solve problems of the prior art, there is provided a kind of branching structure and branch means.
Using the branching structure and branch means, it can significantly increase a point cut-off point for family line, to repair and replacing point family line provides
Facility.
The technical solution of the utility model is as follows：
A kind of branching structure applied to power industry, including a leading-in end and multiple distribution terminals, the leading-in end break
Open or close cable；Each distribution terminal is each turned off or closed cable.
The utility model is relative to the beneficial effect of prior art：
1, by branching structure provided by the utility model, it can effectively increase a point cut-off point for family cable, be easy to
Maintenance and replacing divide family line.
2, by branch means provided by the utility model, its is simple in construction, reliable, manufacturing cost and use cost compared with
It is low, be advantageous to existing point of family line and ammeter transformation.

Fig. 1 is a structural representation of branching structure provided by the utility model.
Fig. 2 is another structural representation of branching structure provided by the utility model.
Fig. 3 is another structural representation of branching structure provided by the utility model.
Fig. 4 is a structural representation of branch means provided by the utility model.
Wherein：1st, leading-in end, 2, distribution terminal.
Embodiment
The utility model is made further instructions with embodiment below in conjunction with the accompanying drawings.
Embodiment 1：
The present embodiment provides a kind of branching structure applied to power industry, and the structure includes a leading-in end and multiple points
Line end, each distribution terminal can be each turned off and close cable.Pass through the leading-in end and 0.4KV three-phase main lines of the branching structure
The one of which connection of road bar, is attached by the multiple exits and multiple points of family lines of the branching structure.It is in use, each
Individual exit closes a point of family cable, and during maintenance, each exit can disconnect corresponding point family cable.
Further, the multiple distribution terminal is arranged to word order.This arrangement mode is simple, reliable, is adapted to use
The less branching pole in family uses.
Further, the multiple distribution terminal is arranged to matrix arrangement.This arrangement mode can be adapted to user more
Branching pole it is practical.
Further, the leading-in end can disconnect and close cable.
The technical scheme that the present embodiment is provided, not only it is adapted to the use of the vast rural areas, while also has obvious
Breakpoint, to safeguard, changing, transforming a point family cable and provide convenience.
Embodiment 2：
The present embodiment provides a kind of branch means of Application Example 1, and the device includes support bar, insulated column, described point
Cable architecture is removably connected by insulated column with support bar.Wherein, support bar is used to be fixedly connected with branching pole, plays support
Point family cable weight does use.Insulated column uses various ways of the prior art, except with insulating effect, additionally it is possible to support
Branching structure and divide family cable.
Further, in addition to wire clamp is concentrated, the concentration wire clamp is arranged on insulated column side by side with branching structure；Concentrate
One end of wire clamp can disconnect and close a cable, and the other end can disconnect and integrate multi-cable.Concentrate one end of wire clamp
It is connected with zero on 0.4KV three-phase main line bars, the other end is connected with the zero of multiple points of family lines.
Further, in addition to multiple porcelain insulators, the multiple porcelain insulator are detachably arranged on support bar.Absolutely
Edge porcelain vase can both wind firewire cable, can also wind zero line cable.At the same time it can also by the position of porcelain insulator, increase
Divide family function by force.
Further, the leading-in end is connected with the phase firewire in three-phase 0.4KV backbone circuits；The multiple separated time
End is connected with each point of family live wire respectively；The electricity at each family is extended to after each point of family live wire one porcelain insulator of winding
Table.
In addition, described one end for concentrating wire clamp is connected with zero in three-phase 0.4KV backbone circuits；The concentration wire clamp
The other end is connected with more points of family zero lines；The electricity at each family is extended to after zero line one porcelain insulator of winding of each point of family
Table.
The technical scheme that practical application embodiment provides, the live wire of each point of family cable, one end is with dividing the one of family structure
The ammeter front end of individual distribution terminal connection, the other end and user connect.The zero line of each point of family cable, is all integrated in concentration wire clamp
One end.But when needs are safeguarded and replacing divides family cable, it is only necessary to by the earth leakage protective device of user（Or main circuit breaker）Disconnect, together
When on branching structure, find corresponding to live wire distribution terminal, disconnect the distribution terminal.The branch means are simple in construction, reliable,
Manufacturing cost and use cost are relatively low, are advantageous to existing point of family line and ammeter transformation.
