Abstract
The invention belongs to power transmission and distribution equipment, and relates to a bus duct joint structure used for conductively connecting two transmission and distribution bus ducts, which comprises two bus ducts with opposite end parts, all phase buses on the two bus ducts correspond to each other to form a multiple-phase bus joint, wherein the bus on one bus duct is provided with a through hole, and the bus on the other bus duct is provided with a vertical slot; an insulating sleeve penetrates through the through hole, one end of the insulating sleeve extends out of the through hole, the bus with the slot to be spliced and positioned with the side of the insulation sleeve through the slot, so as to form a one-phase bus joint, an insulating board is arranged between every two adjacent-phase bus joints; a crossing bolt penetrates the insulating sleeve in each one-phase bus joint and the insulation board between every two adjacent-phase bus joints so as to cross and fix the all-phase bus joints. The invention has compact structure, convenient installation, strong insulating property and low temperature rise during the operation.
Description
Technical field
The invention belongs to equipment for power transmission and distribution, relate to and a kind ofly be used for two sections electrical power distribution busway grooves and conduct 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 by this invention 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 invention includes two sections bus ducts that the end is relative, each phase bus one on two sections bus ducts is corresponding 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, the above-mentioned bus that has slot is pegged graft by slot and insulating case side locate, and forms a phase busbar joint, is 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.
Advantage of the present invention is: 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.
