Description
Technical field
The utility model belongs to the low-voltage electrical power distribution equipment, relates in particular to the wind power tower drum bus duct.
Background technology
Tradition wind energy bus technical scheme is the normal air type bus duct that uses of original static mansion and factory, structural design scheme is to allow busbar be placed in the phase cushion block in phase-splitting behind the wrap insulate medium, bus-bar system has medium insulation and air-insulated double insulation, and the busbar joint junction is that the silver-plated or zinc-plated processing of 200 mm is inwardly done at whole busbar two.Bus is to adopt the single armed lock-on connection device of standard configuration to be connected with the bus connected mode.Be used for the wind energy bus, technical scheme is not done upgrading and is changed, only when bus is installed, in the mounting bracket of bus shell, increase the damping cushion block, can only play a part like this swing of bus buffering, solution bus that can not be in full force and effect waves, so more can not solve rocking of joint 360 degree, burns the potential safety hazard of being brought thereby can not solve the busbar joint temperature rise at all.
When the tower tube is subjected to the wind-force swing, bus also can follow the tower tube to rock, the power of bus swing can discharge in the joint, the burden of bigger connector, long-term swing, collets in the adapter assembly can wear and tear to some extent, the contact point of the aluminium joint in the meeting butt joint assembly forms loosening, influences aluminium joint contact effect, has therefore more accelerated the temperature rise oxidation, final high temperature burns the bus aluminium joint, has influenced the normal operation of wind-powered electricity generation blower fan.
The utility model content
Technical problem to be solved in the utility model is to overcome above technical problem, and a kind of bus duct that can not become flexible, discharge at the contact point place is provided.
The utility model adopt technical scheme be:
A kind of explosion-proof wind energy bus duct, comprise housing and be installed in housing interior insulating part and heterogeneous aluminium foil bus, described aluminium foil bus wherein one joint length is 50 mm～160 mm, expansion cell length is 130 mm～180 mm, expansion cell is converted into V or S type, and described joint and expansion cell are by being welded to connect.
The connected mode decision length of said joint of monomer bus and monomer bus is 50 mm～160 mm, adopts the single armed lock-on connection device of standard configuration to connect, and best joint length is 50 mm～80 mm.Adopt the joint style that connects the overlapping overlap joint of busbar, best length of said joint is 130 mm～160 mm.
The length of expansion cell is according to the height decision of busbar.If the thickness of busbar and height are at 8 mm * 55 mm, 8 mm * 68 mm, 8 mm * 75 mm, expansion cell length is close to 130 mm, if the thickness of busbar and height 8 mm * 110 mm, 8 mm * 130 mm, expansion cell length is close to 180 mm.
Described expansion cell aluminium foil thickness in monolayer is 0.2 mm～0.4 mm, and the aluminium foil gross thickness in the expansion cell is 1.05 times of busbar thickness.
Described expansion cell and busbar partly are provided with insulated tube.
Aluminium foil bending alignment with some, thickness, width can be folded into V or S type.This aluminium foil that is bent into V or S type is welded on the good aluminium connector of surface treatment, and the whole alignment in the other end of aluminium foil is welded on the aluminium bus array and gets final product, and the blank area of the other end of aluminium bus array is also carried out the surface treatment of 200 mm.
The novel wind power bus is when being subjected to the external force swing, the swing that busbar in the bus is not also stopping, the joint is the most fragile, the power of swing can discharge in the joint, because soft aluminium foil connected mode has been adopted in this patent joint, when the power of swing was swung release in the joint, the power of swing arrived the place that is flexible coupling, soft aluminium foil connects the power that can absorb 360 ° swing, and the contact between the connector no longer produces 360 ° of torsion.Joint in the connector and joint contact no longer produce friction, and the insulation chunk between the joint can not rub yet, thus also not wearing and tearing, not wearing and tearing, the joint can not produce loosening, and the junction can not produce high temperature closely, and oxidation is so bus can safe operation.
The beneficial effects of the utility model:
(1) the utility model anti overvoltage ability is strong, dynamic and thermal stability electric current height, and insulation property are reliable;
(2) the utility model joint and joint contact do not produce friction, and the insulation chunk between the joint can not rub yet, not wearing and tearing, and the joint can not produce loosening high temperature.
