Abstract
The invention relates to a bus duct joint conductor current-carrying compensation connecting link. By adopting an abutted joint type connection method, two sections of bus duct conductors are connected in each phase by adopting a single bus duct joint conductor current-carrying compensation connecting link (1); the connecting link is provided with a front side and a back side, the front side is contacted with the bus duct conductors, a raised compensation section transition block (2) is arranged in the middle of the front side, and one or more insulation bolt connection holes (3) are arranged in the middle of the bus duct joint conductor current-carrying compensation connecting link (1). The raised compensation section transition block (2) is arranged on the single connecting link, and a ladder-shaped hole is arranged at a connection position of insulated bolts, so that the abutted limited space of the bus duct can be fully utilized, the maximum utilization of the compensation conductor can be ensured on the basis of saving materials, the requirement of the insulation bolt connection hole of the bus duct joint on an electrical clearance and a creepage distance can also be met, the bus duct joint has the characteristics of being low in temperature rise and reliable in property, which can not be reached in the similar prior art.
Description
Technical field
What the present invention relates to is a kind of current-carrying compensation brace of bus duct joint transition bonding conductor, belongs to low pressure electrical power distribution busway groove technical field.
Background technology
The conductor method of attachment of existing bus duct joint is two kinds, 1, plug-in type; 2, dock.
Plug-in type is to utilize the electric conductor of the busbar of bus duct body to peg graft, because insulated bolt need take the requirement of conductive section space and electric clearance and creepage distance, the conductive section of busbar joint can not be utilized as bus bars cross section (application number 200910026471.9).There is following drawback in this mode, and the one, small-volume bus duct exists conductive contact surfaces inadequate, causes busbar joint heating, temperature rise, and ampacity does not reach the electric conductivity requirement equal with bus bulk; The 2nd, peg graft difficult, inconvenience is installed, and joint is with directivity, gives and manufactures, installs and bring very large difficulty.
Dock busbar joint is space and electric clearance and the creepage distance of guaranteeing insulated bolt, and the two-sided brace of employing connects two sections of busbars (as the ZL patent No. 200420021023.2, application number 201020134486.5).Although this mode adopts two-sided brace to increase contact-making surface, the cross section of the position that insulated bolt takies does not obtain structural improvement, and high material consumption, complex structure, joint volume are large, uneconomical practicality.
Summary of the invention
technical problem:object of the present invention, be intended to solve existing busbar joint bonding conductor because of the cross section that insulated bolt locational space and electric clearance, creepage distance lose bonding conductor, provide a kind of performance safety reliable, save manufacturing cost, novel bus trough connection conductor current-carrying compensation brace easy for installation.
technical scheme:a kind of bus duct joint conductor current-carrying compensation brace of the present invention adopts the method for attachment of dock, often adopts mutually independent a slice bus duct joint conductor current-carrying compensation brace that two sections of bus duct conductors are coupled together; This brace is divided into positive and negative two sides, and front contacts with bus duct conductor, in the middle of positive, is provided with a protruding compensation section transitions piece, is provided with one or more insulated bolt connecting holes in the centre of bus duct joint conductor current-carrying compensation brace.
The insulated bolt connection hole in described bus duct joint conductor current-carrying compensation brace front, is provided with creepage distance shoulder hole, makes insulated bolt connecting hole become shoulder hole, meets electric clearance and creepage distance technical requirement.
The insulated bolt connection hole of described bus duct joint conductor current-carrying compensation brace reverse side, is provided with insulating case counter sink.
beneficial effect:the present invention arranges protruding compensation section transitions conducting block owing to having adopted on monolithic brace, and at insulated bolt link position, shoulder hole is set, take full advantage of the confined space of bus duct docking, on the basis of saving material, ensure the maximum using of compensating conductor, the requirement of the insulated bolt connecting hole that has met again bus duct joint to electric clearance and creepage distance, making bus duct joint have that temperature rise is low, the feature of dependable performance, is that current similar technology institute is inaccessiable.Adopt the mode of monolithic brace, not only easy for installation, and reduced bus duct joint volume.
Brief description of the drawings
Fig. 1 is front view of the present invention,
Fig. 2 is cross section view of the present invention,
Fig. 3 is rearview of the present invention.
In figure, have: bus duct joint conductor current-carrying compensation brace 1, compensation section transitions conducting block 2, insulated bolt connecting hole 3, insulating case counter sink 31, creepage distance shoulder hole 32.
Embodiment
Technical problem to be solved by this invention is how to make full use of limited space to compensate insulated bolt and take the conductive section that bus duct joint link position loses, and guarantees most effectively electric clearance and creepage distance simultaneously, accomplishes safe and reliable.
The method of attachment that bus duct joint bonding conductor of the present invention adopts is dock, often adopts mutually independent a slice bus duct joint conductor current-carrying compensation brace 1 that two sections of bus duct conductors are coupled together; This brace is divided into positive and negative two sides, and front contacts with bus duct conductor, in the middle of positive, is provided with a protruding compensation section transitions piece 2, is provided with one or more insulated bolt connecting holes 3 in the centre of bus duct joint conductor current-carrying compensation brace 1.
Insulated bolt connecting hole 3 places in described bus duct joint conductor current-carrying compensation brace 1 front, are provided with creepage distance shoulder hole 32, make insulated bolt connecting hole 3 become shoulder hole, meet electric clearance and creepage distance technical requirement.
Insulated bolt connecting hole 3 places of described bus duct joint conductor current-carrying compensation brace 1 reverse side, are provided with insulating case counter sink 31.
Claims (1)
1. a bus duct joint conductor current-carrying compensation brace, is characterized in that adopting the method for attachment of dock, and every independent a slice bus duct joint conductor current-carrying compensation brace (1) that adopts mutually couples together two sections of bus duct conductors; This brace is divided into positive and negative two sides, front contacts with bus duct conductor, in the middle of positive, be provided with a protruding compensation section transitions piece (2), be provided with one or more insulated bolt connecting holes (3) in the centre of bus duct joint conductor current-carrying compensation brace (1);
The positive insulated bolt connecting hole (3) of described bus duct joint conductor current-carrying compensation brace (1) is located, be provided with creepage distance shoulder hole (32), make insulated bolt connecting hole (3) become shoulder hole, meet electric clearance and creepage distance technical requirement;
