Abstract
The invention discloses a busbar insulating layer manufacturing method which comprises the following steps of 1), heating the busbar; 2), placing the busbar into a fluidizing trough which is internally provided with insulating powder for coating; 3), taking the busbar out of the fluidizing trough, and performing heating curing for forming an insulating layer. Therefore a compact insulating layer can be formed on the surface of the busbar. The insulating coating has good flame retardance (UL V0 grade), good insulating performance (20kV / mm), good high-temperature resistance (insulating heat-resisting grade of H-grade at a temperature of 180 DEG C), high wear resistance, high impact resistance and high adhesion force. Therefore high insulating and heat-resisting grade, low aging speed, long-term high-temperature operation of the busbar insulating layer are realized, and furthermore a current peak current load requirement is satisfied. The busbar insulating layer is suitable for steam erosion in wet and hot environments such as basement and oceanside environment. Furthermore the busbar insulating layer manufacturing method has advantages of simple product structure and automatic batchoperation.
Description
technical field [0001] The invention relates to the technical field of busbar insulation in bus ducts, in particular to a method for manufacturing a busbar insulating layer. Background technique [0002] At present, the busbar insulation in the busway mainly adopts heat-shrinkable sleeve heat-shrinkable sleeve, coated with polyester film sleeve, wrapped with polytetrafluoroethylene tape, mica tape and other materials as insulating materials. Because of the different material components, each The lifetime of the material is inconsistent. The heat-resistant grade of heat-shrinkable sleeve insulation is Class E 105°C, and the heat-resistant grade of polyester film insulation is Class B 130°C. Inconsistent heat-resistant insulation grades result in different life spans for the same product. In terms of processing technology, the heat-shrinkable sleeve is simple, but if the heat is uneven, the thickness will be inconsistent, and the temperature will be too high. To a certain ex...
