Description

A kind of 0.4 kilovolt of aerial branch, power supply line downlead bracket

Technical field

The utility model relates to power supply line's downlead support technology field, specially a kind of 0.4 kilovolt of aerial supply lines Road branch downlead bracket.

Background technique

Currently, 0.4 kilovolt of aerial power supply backbone road in supply network, later maintenance and entrance line wiring work be all Cut carries out on basic routing line, belongs to damageability operation, as social economy is increasingly developed, user's high-power electric appliance increasingly increases It is more, so that supply load is surged rapidly, 0.4 kilovolt of downlead access gradually increases, and route cut number increases significantly therewith, can make It is reduced at the security and stability of basic routing line, accesses simultaneously it is also possible to not press standard technology because of downlead, is multiple at single cut The influence of the factors such as access, causes the failure rate of 0.4 KV line to increase, can also cause security risk and electric power thing Therefore and may lead user's low-voltage damage, and be unfavorable for low voltage three-phase uncompensated load adjustment, or even cause transformer and The equipment scaling loss such as power distribution cabinet, causes many security risks.

In the connection of 0.4 kilovolt of basic routing line and branch's downlead, there are construction personnel to carry out violation operation, single It is repeatedly tied up at cut, causes at the cut that the irregular cross section of conducting wire increases or even some are adopted at downlead branch joint With simple winding violating the regulations, these non-standard operations will cause: contact resistance increases at insulated conductor cut access, 0.4kV power supply Under basic routing line and branch's downlead junction long-play state, accelerates conductive contact surface oxidation film and formed, make joint Resistance increases, Yi Chengwei heat generating spot, meanwhile, insulated conductor cut is in load boom period, and electric current is uprushed, and access point is caused to be sent out Heat；When short trouble occurs for line system, overcurrent makes the access point or defective access point of off-capacity, fuses Or virtually connect, cause to be unable to normal power supply；Route cut part outdoors long-play when due to expanding with heat and contract with cold, or It is vibrated for a long time, joint looseness can be made, basic routing line or downlead fracture, cause safety accident at access.

Therefore existing 0.4 kilovolt of aerial branch, power supply line downlead method there are wiring disorderly and unsystematic, safety of initiation The case where hidden danger, low-voltage, line loss height, controller switching equipment scaling loss.

Utility model content

The purpose of this utility model is to provide a kind of 0.4 kilovolt of aerial branch, power supply line downlead brackets, to solve The disorderly and unsystematic problem of wiring mentioned above in the background art.

To achieve the above object, the utility model provides the following technical solutions: a kind of 0.4 kilovolt of aerial branch, power supply line Downlead bracket, including downlead connect busbar, are connected with porcelain insulator on the downlead connection busbar, and on porcelain insulator Lower both ends pass through bolt and connect busbar connection with downlead, connecting plate have been bolted in the middle part of the porcelain insulator, institute It states in downlead connection busbar and offers busbar preformed hole.

Preferably, the downlead connection busbar and connecting plate are located at the two sides of porcelain insulator.

Preferably, the horizontal direction central axes of downlead connection busbar and porcelain insulator are overlapped, and connecting plate and absolutely The junction of edge porcelain vase is located on the horizontal direction central axes of porcelain insulator.

Preferably, the busbar preformed hole is equipped at least two, and busbar preformed hole vertical direction central axes and downlead connect Connect the coincidence of busbar vertical direction central axes.

Compared with prior art, the utility model has the beneficial effects that 0.4 kilovolt of aerial branch, power supply line downlead Bracket can be in downlead wiring without carrying out damageability operation, and order advises the management of 0.4 kilovolt of aerial power supply line more Model.Busbar preformed hole is offered in the downlead connection busbar of this 0.4 kilovolt of aerial branch, power supply line downlead bracket, enables behaviour Make on the busbar preformed hole that wiring can be mounted in downlead connection busbar by personnel when carrying out downlead wiring, without 400V basic routing line can be effectively protected on power supply line's backbone, being not in damageability operation in installation, avoid because Conducting wire damages caused by basic routing line repeats cut.
