The bus conductor comprises a conductive bus bar, wherein, tinning layers are arranged at the end parts of the conductive bus bar, and an epoxy powder spraying insulating layer is solidified at the middle part of the conductive bus bar. The utility model has the advantages of fine insulating performance, good heat dissipation effect, strong damp resistant and corrosion resistant ability, long service life, and safe and reliable operation.
Description
Technical field
The utility model belongs to equipment for power transmission and distribution, relates to the structure of electrical power distribution busway, specifically is a kind of bus-bars conductor of band epoxy resins powder spraying insulating barrier.
Background technology
In the electrical power distribution busway device, when the bus-bars conductor surface need be provided with insulating barrier, traditional method is the following several modes of employing mostly: the coating of polyester cover, PER film or polytetrafluoroethylene film twine, overlap thermal contraction casing tube.Such insulating process backwardness, poor reliability, the class of insulation is low, dielectric strength is low, loss of properties on aging, especially the insulation of conductor corner is difficult to solve, also can't eliminate the condensation phenomenon that between conductor and insulating barrier, occurs in the power supply process, seriously restrict the development of bus duct.
Summary of the invention
Technical problem to be solved in the utility model is, provides that a kind of good insulation preformance, good heat dissipation effect, moisture proof and resistance to corrosion are strong, the bus-bars conductor of long service life, band epoxy resins powder spraying insulating barrier safe and reliable to operation.
The bus-bars conductor of band epoxy resins powder spraying insulating barrier of the present utility model includes conductive bus bar, and there is tin coating the end of conductive bus bar, at conductive bus bar stage casing surface cure one deck epoxy powder spraying insulating barrier is arranged.
The good effect that the utility model produced is embodied in:
1. the epoxy resins insulation powder coating closely contacts with busbar, exhibit excellent moisture barrier properties, and can make spatial design compacter.Adopt high performance epoxy resins insulation powder when cross-linking reaction, can generate certain chemical bond with busbar, and unlike heat-shrinkable T bush, be that simple physics combines with busbar, so bonding force and compactness improve greatly, can use the environment of various humidities fully.Simultaneously, the epoxy resins insulation powder coating has good dielectric strength (39V/um), under the identical voltage withstand class coating layer thickness far below traditional heat-shrinkable T bush, thereby make busbar compact more.
2. the surface is tough and tensile, attractive in appearance.The smooth smooth not alice of insulating coating forms tough and tensile insulating barrier behind hot setting, have stronger shock resistance, makes the insulation property safety and reliability of conductor.No matter splendid levelability is arranged after the epoxy resins insulation powder is heated, be that the busbar of what shape and specification can perfect apply close attachment.And can look like traditional thermal shrinkable sleeve, and producing wrinkle in the elbow, bubble has reduced potential safety hazard.
3. insulation system temperature rank height, under higher working temperature, the coating deliquescing of can not being heated.The epoxy resins insulation powder is the thermosets with good electrical performance, is thermoplastic unlike traditional thermal shrinkable sleeve, and it is too high and burnt with regard to easy deliquescing even Yin Wendu to be heated, and has improved the fail safe of equipment.
4. the epoxy resins insulation anti-corrosion resin has fabulous thermal conductivity, and coating and copper bar combine closely (not having the air gap), so thermal radiation (heat radiation) effect under equal conditions is better than naked row (the temperature rise test test result: naked copper is arranged 43 ℃, and the copper bar temperature is 35 ℃ under the coating).The naked row of copper bar temperature rise ratio is lower under the bus-bars conductor insulating coating that employing the inventive method is handled, and not only need not fall appearance, can rise appearance on the contrary.And thermal shrinkable sleeve unnecessarily is retained in the busbar heat because thermal conductivity is low and the existence of thermal insulation air gap, so the more naked row of temperature is high, thereby has to fall appearance, increases cost.
5. outstanding ageing-resistant performance, longer service life.The epoxy resins insulation anticorrosive powder has good aging properties, and useful life is apparently higher than the heat-shrinkable T bush that adopts PP and PE material.
6. good antiseptic property is applicable to various abominable engineering-environments.Epoxy resins insulation anticorrosive powder good antiseptic property and wideer working temperature can allow bus use in various rugged environments, as the area, plateau, wet environment, the chemical plant, pollute than serious area in cement plants etc., and obviously improve security and stability and useful life in these heavily contaminated areas.
7. the saving material reduces cost, and stability improves the quality.Different shape, the all available a kind of powder spraying of the busbar of all size and voltage withstand class, reach insulation and corrosion-resistant requirement, unique what need to change is exactly the thickness of coating, has avoided the quality unsteadiness that the thermal shrinkable sleeve of unlike material brings and has reduced workload and waste of material that the thermal shrinkable sleeve cutting increases.

Fig. 2 is the cross section structure for amplifying schematic diagram of Fig. 1.
Embodiment
As shown in the figure, the bus-bars conductor of band epoxy resins powder of the present utility model spraying insulating barrier comprises the tin coating 3 of conductive bus bar 1, end and is solidificated in the epoxy powder spraying insulating barrier 2 of section surface in the conductive bus bar.
The generation method of described epoxy powder spraying insulating barrier is: after the conductive bus bar preheating after zinc-plated, with electrostatic coating method epoxy powder is evenly sprayed on the conductive bus bar surface in electrostatic spraying device, the conductive bus bar that will spray epoxy powder is then sent into baking oven heating back cooling curing.
Described electrostatic coating method is a common process, its principle is: the principle of utilizing the high-pressure electrostatic corona field, put at gun head metal water conservancy diversion and to connect high voltage negative, spray workpiece grounding to form positive pole, make stronger static electric field of formation between spray gun and the workpiece.When compressed air as carrier gas, with powder to be sprayed from powder barrel when tube cell is delivered to the diversion rod of spray gun, because diversion rod connects the corona discharge that high voltage negative produces, produced intensive negative electrical charge in its vicinity, make negative electrical charge on the powder belt, and entered the very high electrostatic field of electric field strength, under the double action of electrostatic force and carrier gas, powder flies to the ground connection workpiece equably, forms the uniform powder bed of thickness on its surface.
