Background technique

In the power system, it often involves the work of connecting and wiring, especially the line connection from the main line to the branch. There are dozens to hundreds of household lines in each low-voltage distribution station area, so thousands of integrated distribution stations In the area, there are hundreds of thousands of household lines, so hundreds of thousands of connections will be generated at the same time. When the overhead lines are bare wires, most of the household lines and overhead lines are directly connected. Improper connection method and insufficient connection process lead to poor contact at the connection, increased resistance, long-term overheating and burning of the main line, and the connection is very chaotic and unsightly; with the construction and renovation of the new electrified countryside, Part of the overhead bare wires were replaced with overhead insulated wires, and line clips were used to connect the household wires and overhead insulated wires. When connecting, the insulation layer is continuously stripped on the overhead wire, which is inconvenient to work and affects the insulation of the overhead wire. A slight mishandling will prevent water from entering the overhead insulation wire, which will cause serious corrosion after a long time, especially The neutral line is more pronounced.

In order to solve this problem, there is an urgent need for a special solution for the connection between the household line and the overhead main line, which can facilitate the construction operation, reduce the construction time, effectively reduce the contact resistance, reduce the line loss rate of the low-voltage station area, and make the connection The connection of household lines is neat, uniform, orderly and beautiful, and it is a device that realizes the standardization of construction technology. the

The technical problem to be solved by this new model is to provide a multi-branch connection board, which has simple structure, firm connection, convenient construction and operation, shortens construction time, effectively reduces contact resistance, reduces line loss rate in low-voltage station area, and makes the connection line The connections are neat, unified, orderly and beautiful, and it is easy to realize the standardization of construction technology.

In order to solve the above technical problems, the technical solution adopted by the utility model is a multi-branch connection board, including a conductive main board, an overhead wire slot is arranged on the conductive main board, and in the vertical direction of the overhead wire slot, a row of There is an overhead line pressing plate on the overhead line slot, and an overhead line pressing plate is provided on the connecting line slot. Fastened to conductive motherboard.

Further speaking, both the overhead line pressing plate and the household line pressing plate are provided with wire slots, half of the slot holes of the wire slots are set on the overhead line pressing plate and the household line pressing plate, and half are set on the conductive main board. The conductive main board is an inverted T shape, the overhead wire groove is arranged horizontally on the upper part of the conductive main board, and the household wire groove is vertically arranged on the lower part of the conductive main board. The materials of the conductive main board and circuit pressing plate are all aluminum, all copper or copper-aluminum transition materials. Two screws are used to fix the conductive main board and the circuit pressing plate. The size of the conductive main board can be determined according to actual needs. Generally speaking, there is an overhead line slot on the upper part of the conductive main board, which is used for the overhead line to pass through horizontally. It is perpendicular to the overhead wire trough. When in use, the user wire can be directly inserted into the wire trough, pressed by the user wire pressure plate and fixed with screws, and conducts electricity through the conductive main board itself.

The beneficial effects of this new type are: simple line wiring, time-saving and labor-saving construction, and installing a multi-branch connection board on each phase overhead main line at the same base pole, which can meet the connection of multiple household lines and save construction time , improve the reliability of power supply and reduce the occurrence of accidents. Using the multi-branch connection board can make the connection point in good contact and achieve the purpose of no corrosion for a long time. It can also make the connection of the access line neat, uniform, orderly and beautiful, and realize the standardization of construction technology.
