Abstract
The pipe bus end calibre of the inventive hollow four-side joint copper, aluminium pipe bus and copper multiple tube bus (steel pipe or aluminium pipe is claded in the copper pipe) is moulded into four hollow copper and aluminum conducting surfaces by a punching technology. The suitable mould are configured according to actual carrying capacity requirement and the requirement of bus calibre, to process the conducting surfaces (shapes such as a square, a rectangle and two plane ellipse). Since it is an integrated one withou link bit and contacting resistance, thus ensuring the end of the bus will not have a high temperature, and will have safe operation.
Description
Technical field
Hollow four-side connector of the present invention is specially adapted to carry the contact tube bus of the big electric current of power frequency to be connected use with equipment.The live flow is big, and temperature rise is low, and the mechanical strength height improves operating safety factor.
Background technology
The existing contact tube busbar joint (patent No.: 01215457.1), in the actual installation process, exist shortcoming as follows: because the contact tube bus is circular, with need install conversion gold additional in the equipment connection procedure, be converted to the plane by disc, be connected with other equipment by rectangular conductor.1, the pipe bus is connected with equipment and need installs conversion gold cost height additional, and waste material consumes energy.2, original joint has only 2 conductive planes, and sectional area is little, and conductor divides, it is uneven to exist electric current to distribute when carrying electric current, wherein 1 conductive plane conductor overcurrent is little, and 1 conductive plane conductor overcurrent is excessive in addition, and that face that overcurrent is big can produce high temperature.3, pipe bus end is connected with conversion gold, can produce contact resistance, because the existence of contact resistance is arranged, under the situation of carrying big electric current, pipe bus end and conversion gold can produce excessive heating, and heat is big more, and resistance is high more, it is serious more to generate heat, because high temperature can cause and blow pipe bus, phase fault, shorted to earth or initiation fire and cause bigger accident.
Summary of the invention
The objective of the invention is to overcome the shortcoming of prior art, a kind of simple in structure, hollow four-side connector that can effectively solve end-heating is provided.
The technical scheme one that realizes the object of the invention is: hollow four-side connector of the present invention, be with diameter of phi 30mm～500mm, the end caliber of wall thickness 1mm～30mm copper, aluminum tube bus, copper composite pipe bus (composite steel tube or aluminum pipe in the copper pipe) passes through 4 conducting surfaces of die stamping moulding with punch press or hydraulic press, disposes the mould that adapts according to the requirement of actual ampacity requirement and bus caliber and processes conducting surface (shape has square, rectangle, 2 oval in plan).The electric current surface is evenly distributed, heat-dissipating space is arranged, cooling surface area is big, the conducting surface surface area is greater than the conductive area of original all tube bus connectors, do not need to install additional conversion gold, reduce contact resistance, directly by these stamping forming 4 conducting surfaces by connector and rectangular conductor or be flexible coupling fastening, be connected with miscellaneous equipment by being fastened on the rectangular conductor on the hollow four-side connector or being flexible coupling again, according to the requirement of ampacity, select 1 conducting surface again, 2 conducting surfaces, 3 conducting surfaces, 4 conducting surfaces, this just forms hollow four-side connector.
The technical scheme two that realizes the object of the invention is: because of copper, aluminum tube bus, copper composite pipe bus (composite steel tube or aluminum pipe in the copper pipe) is to carry big electric current, the conducting surface of copper, aluminum tube bus, copper composite pipe bus (composite steel tube or aluminum pipe in the copper pipe) end directly be flexible coupling or rectangular conductor is connected, this connecting portion pipe bus end conducting surface is local with the contact area that is flexible coupling or rectangular conductor is connected, the conducting surface connecting portion of pipe bus end also causes this connecting portion heating easily because net sectional area is little.The scheme that solves this defective is by strengthening the sectional area of copper, aluminum tube bus, copper composite pipe bus (composite steel tube or aluminum pipe in the copper pipe) end, reach the end ampacity and increase, not generating heat.Concrete scheme is as follows: 1, outer compound---be inserted in and manage the copper with certain-length, the aluminum metal cover that the bus outer end diameter matches in pipe bus outer end diameter, the thickness of this metallic sheath is 1～30mm, by diameter enlarging method or undergauge method, this metallic sheath and pipe bus end are closely linked together.This diameter enlarging method is to closely linking together with outer copper, aluminum metal cover with copper, aluminum tube bus, copper composite pipe bus (composite steel tube or aluminum pipe in the copper pipe) inner end diameter hole enlargement; The undergauge method is that outer copper, aluminum metal cover undergauge and copper, aluminum tube bus, copper composite pipe bus (composite steel tube or aluminum pipe in the copper pipe) outer end diameter are closely linked together.2, interior compound---be inserted in and manage the copper that the bus inner end diameter matches in pipe bus inner end diameter with certain-length, the aluminum metal cover, the thickness of this metallic sheath is 1～30mm, by diameter enlarging method or undergauge method, this metallic sheath and pipe bus end are closely linked together, this diameter enlarging method is with copper, the hole enlargement of aluminum metal cover internal diameter to and copper, aluminum tube bus, copper composite pipe bus (composite steel tube or aluminum pipe in the copper pipe) inner end diameter closely links together, and the undergauge method is with copper, aluminum tube bus, copper composite pipe bus (composite steel tube or aluminum pipe in the copper pipe) end diameter reducing and outer copper, aluminum metal cover external diameter closely links together.Again will be the long-pending copper of enlarging section, aluminum tube bus, copper composite pipe bus (composite steel tube or aluminum pipe in the copper pipe) end caliber with punch press or hydraulic press by 4 conducting surfaces of die stamping moulding, process conducting surface (shape has square, rectangle, 2 oval in plan) according to the mould that actual ampacity requires and the requirement configuration of bus caliber adapts.Directly by these stamping forming 4 conducting surfaces by connector and rectangular conductor or be flexible coupling fastening, be connected with miscellaneous equipment by being fastened on the rectangular conductor on the hollow four-side connector or being flexible coupling again, again according to the requirement of ampacity, select 1 conducting surface, 2 conducting surfaces, 3 conducting surfaces, 4 conducting surfaces, this just forms hollow four-side connector.
The invention has the beneficial effects as follows: owing between 4 conducting surfaces of hollow four-side connector certain distance is arranged: 1, be convenient to be connected with miscellaneous equipment; 2, strengthen heat-dissipating space; 3, the end section strengthens, and helps reducing the temperature rise of end-fitting; 4, because hollow four-side connector is directly in bus end punch forming integral type, connect the position, there is not contact resistance, reduce caloric value, ampacity is big, guarantees that the end of bus can not produce high temperature, safe operation; 5, because hollow four-side connector is that integral type has been cancelled original conversion gold, directly reduce cost, reduce weight, the minimizing consumptive material of bus, save non-ferrous metal, save the energy.
