Abstract
The utility model belongs to power transmission and distribution equipment, in particular relates to a bus duct connector structure used for electrically connecting two sections of power transmission and distribution bus ducts. The structure comprises two sections of bus ducts of which the end parts are opposite, multiphase busbars on the two sections of bus ducts are one to one corresponding to form a multiphase bus connector, a through-hole is formed on a bus in one section of bus duct, and a longitudinal slot is formed on a bus in the other section of bus duct; an insulation sleeve penetrates through the through-hole, one end of the insulating sleeve extends the through-hole, so as to ensure the bus with the slot to be spliced and positioned on the side surface of the insulation sleeve through the slot, to form a one-phase bus connector, and a layer of insulation board is arranged between the bus connectors with adjacent phase; and all the bus connectors with various phase are connected and fixed by a cross-under bolt penetrating through the insulation sleeve in each one-phase bus connector and the insulation board between multiphase bus connectors. The structure has the advantages of compact structure, convenient installation, strong inter-phase insulating capacity and low temperature rise during operating process.
Description
Technical field
The utility model belongs to equipment for power transmission and distribution, relates to a kind ofly being used for two sections electrical power distribution busway grooves and conducting electricity the bus duct joint structure that connects.
Background technology
Traditional bus duct is when the connection of carrying out between two sections, usually adopt special-purpose splicer to conduct electricity to connect and fixing, splicer will partly be made up of middle conducting connecting part, insulating part and firm etc. usually, conducting connecting part need consume more electric conducting material in the middle of it, has improved cost; In addition, because two sections buses connect by middle conducting connecting part transition, joint is more, has improved the resistance of blank area, causes that running generates heat seriously, transmission losses is big.
Summary of the invention
Technical problem to be solved in the utility model is, provide a kind of compact conformation, easy for installation, the phase insulation ability strong, the low line raceway arrangement structure of temperature rise in the running.
Bus duct joint structure of the present utility model includes two sections bus ducts that the end is relative, each phase bus on two sections bus ducts is corresponding one by one to form heterogeneous busbar joint, wherein have through hole on the bus in one section bus duct, and have slot longitudinally on the bus in another section bus duct; Be installed with an insulating case in the described through hole, an end of insulating case stretches out through hole, make above-mentioned have slot bus by slot and the insulating case side location of pegging graft, form a phase busbar joint, be separated with one deck insulation board between the busbar joint of adjacent phase; Insulating case in each phase busbar joint of a cross-under bolt-through and the insulation board between each phase busbar joint are arranged, the busbar joint cross-under of all phases is fixed.
Described through hole has one section counterbore that diameter is bigger towards an end of adjacent phase bus, and external diameter one end of insulating case has one section bigger ladder section of diameter that sinks in the above-mentioned counterbore simultaneously.
The utility model has the advantages that: the blank area of two sections buses is directly overlapped, reduced connection resistance and temperature rise, reduced operating power consumption; 2, save middle conducting connecting part in the traditional jointing device structure, reduced material consumption; 3, because step-like through hole and step-like insulating case match, increase alternate creepage distance, improved alternate insulating capacity.
