The concept of compact pressure coefficient, which is in order to understand, the conductor fill factor also known as compression coefficient normally only the equivalent of the name, in the not really understand the meaning of the tight
pressure coefficient under the condition of this title is very easy to make people think that since the pressure coefficient, the lower pressure should be the tighter the value, it should be a wrong understanding. The tight pressure coefficient is the ratio that usually intuitive effective sectional area of compression and tension after pressure before or after pressing the outline of section (or conductor) and the profile section is pressed before (or the conductor diameter ratio).
These two kinds of understanding are not correct. A conductor can only reflect the degree of stretching and compression can not reflect the extent of the latter cannot accurately reflect the degree of pressure tight, imagine, if under the ideal condition the conductor pressing zero clearance, and After the pressure is still tight under the action of external force, tensile, tight ratio contour area outline area after pressure and pressure before will be one with the change of tensile strength value. This is not reflect the pressing degree. According to the definition of filling coefficient, as long as the actual section and profile after pressing the same is pressed coefficient is 1, i.e. zero clearance, no matter how stretch, remains the filling coefficient of.JEM motor wiring 在一些地方,經(jīng)??吹揭恍┱f(shuō)法,比如說(shuō)緊壓系數(shù)一般是0.89-0.92,不可能達(dá)到0.85,這就顯得有些沒(méi)道理了,應(yīng)該說(shuō)是緊壓系數(shù)一般是0.89-0.92,不可能達(dá)到0.98才對(duì),因?yàn)?.85的緊壓系數(shù)是壓得很松的.而不是壓得很緊.一次緊壓其緊壓系數(shù)相對(duì)較小,而分層緊壓要大一些.
In some places, often see some claims, such as tight pressure coefficient is generally 0.89-0.92, could not reach 0.85, which is somewhat unreasonable, should be said that 0.89-0.92 is generally not tight pressure coefficient could reach 0.98, to 0.85, because of the tight pressure coefficient is very loose. Instead of pressure very tight. Once pressed the tight pressure coefficient is relatively small, and layered pressed to a large number.
