The tube bus end part diameter of the related copper, aluminum tube bus, copper composite tube bus (copper tube inner composite steel tube or aluminum tube) is stamped and molded with stamping technics into four hollow copper and aluminum conductive surfaces; conductive surfaces (the shapes are a square, a rectangle and two plane ellipse) are processed through matching suitable mould according to requirements of practical current carrying capacity and requirements of bus tubular diameter, due to the integral type without connecting bit, the resistance is not contacted, thereby ensuring the end part of the bus not producing high temperature and safe operation.

Description

The pipe bus that has hollow four-side connector

Technical field

The utility model relates to a kind of pipe bus, and particularly a kind of being applicable to carries the big electric current of power frequency to be connected the contact tube bus that uses with equipment, and its live flow is big, and temperature rise is low, and the mechanical strength height improves operating safety factor.

Background technology

Existing contact tube bus exists shortcoming as follows in the actual installation process: because the contact tube bus is circular, and 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.

The utility model content

The purpose of this utility model is the shortcoming that overcomes prior art, and a kind of simple in structure, pipe bus that has hollow four-side connector that can effectively solve end-heating is provided.

The technical scheme one that realizes the utility model purpose is: hollow four-side connector of the present utility model, 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 utility model purpose 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 complex copper with certain-length, the aluminium lamination 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 complex copper, aluminium lamination 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 complex copper, aluminium lamination 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 complex copper that the bus inner end diameter matches in pipe bus inner end diameter with certain-length, aluminium lamination, 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 complex copper, the hole enlargement of aluminium lamination 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 complex copper, the aluminium lamination 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 beneficial effects of the utility model are: 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.
