Abstract
The present invention provides an interbus for connecting a tie cabinet with a switch cabinet, which comprises three single-phase buses, namely an A bus, a B bus and a C bus. Each single-phase bus comprises a conductive rod and an epoxy resin sleeve which is sleeved outside the conductive rod. A first joint of the single-phase bus is arranged in the vertical direction and is provided with a first threaded hole which is matched with a wire outlet end of the tie cabinet. A second joint of the single-phase bus is arranged in the horizontal direction, and furthermore one end of the second joint is provided with a second threaded hole which is matched with the wire inlet end of the switch cabinet. At least two leg brackets are arranged below the single-phase buses. Each leg bracket is provided with a third threaded hole which is fixed with the switch cabinet. The interbus for connecting the tie cabinet with the switch cabinet has the advantages of: good insulating effect, convenient mounting and remarkable space saving effect.
Description
Technical field
The present invention relates to a kind of wire, particularly a kind of for connecting the interbus of contact cabinet and switch cubicle.
Background technology
Bus contact cabinet is also bus section cabinet, the equipment for connecting left and right sides bus, in sectionalized single busbar connection, double-bus configuration system, usually to use bus contact cabinet, select the requirement of different running method or guarantee selectively to excise load under failure condition to meet user, be convenient to selectively power supply and maintenance of equipment.
Interbus is the important component part of contact cabinet, plays the effect of connection and transmission of electric energy in ring main unit.The mode of interbus has directly determined the liaison method of contact cabinet.The interbus of most high pressure contact cabinet all adopts rectangular copper bar to connect, and this liaison method is made simple, easy for installation, but owing to having adopted a large amount of copper bars, therefore cost is higher.
Part producer adopts the mode of cable to get in touch with in addition, due to the arbitrarily bending of cable softness, therefore easy construction, and good insulation preformance.But due to cable softness, be difficult for fixing.Therefore in the time that electric current is larger, can under electrodynamic action, shake, there is certain potential safety hazard.
Although, there is part producer to increase an empty cabinet, in empty cabinet, only part adopts copper bar to connect, and realizes contact.But the increase of high-voltage board quantity means the increase of floor space and the waste of resource, also causes the increase of production cost.
Summary of the invention
The technical problem to be solved in the present invention is that interbus cost is high, large, unsafe defect that takes up room in using in order to overcome in prior art, provide a kind of low cost, easy for installation, use safety for connecting the interbus of contact cabinet and switch cubicle.
The present invention solves above-mentioned technical problem by following technical proposals: a kind of for connecting the interbus of contact cabinet and switch cubicle, described interbus comprises A line, B line, three single-phase buses of C line, its feature is, described single-phase bus comprises a contact rod and is set in the epoxy resin cover outside described contact rod, the first joint of described single-phase bus is vertical direction and is provided with the first screwed hole matching with the leading-out terminal of described contact cabinet, the second joint of described single-phase bus is that horizontal direction and one end are provided with the second screwed hole matching with the end of incoming cables of described switch cubicle, the bottom of described single-phase bus is provided with at least two foot supports, described foot support is provided with three screwed hole fixing with described switch cubicle.Described interbus is arranged on the inlet wire position that line position and adjacent switch cabinet of contact cabinet, has realized contact cabinet and has been connected with the bus of other switch cubicle.Determine described interbus material and cross-sectional area according to the rated current of ring main unit
Preferably, described contact rod is a red copper bar.Because red copper good conductivity is corrosion-resistant, plasticity is strong, and ductility is good, and easily processing, so contact rod is preferentially selected red copper bar.
Preferably, the sectional area of described red copper bar is greater than 700 square millimeters.Adopt 700mm
2red copper material, the ring main unit of rated current 1250A has enough used.
Preferably, the thickness of described epoxy resin cover is greater than 6 millimeters.The compressive resistance of epoxy resin is at 18kV/mm, and the epoxy resin average thickness that promotes bus is about 6mm, has met the insulating requirements of 10kV ring main unit completely.
Preferably, described the 3rd screwed hole is M8 screwed hole.This can be fixed on cabinet foot support.
Preferably, the other end of described the second joint is an installing hole and uses silica gel sealing ring and the sealing of insulation plug.Described installing hole needs make can with and cabinet bus is connected, do not need with and cabinet bus when being connected, seal with described silica gel sealing ring and described insulation plug, can guarantee all insulation of interbus.
Positive progressive effect of the present invention is: a kind of simple installation, space-saving for connecting the interbus of contact cabinet and switch cubicle is provided.
