The difference between lap and stitching
Power and load are angular and star connection. When the power supply is connected, the phase voltage of the power supply is equal to the line voltage. The line voltage of the star load is equal to the line voltage of the power supply. The phase voltage of the load is equal to the line voltage divided by the root number. When the power supply is connected, the line voltage of the power supply is equal to three times the root number of the power supply phase voltage. The line voltage of the corner load is equal to the line voltage of the power supply, and the phase voltage is equal to the line voltage. Both at the same time using the corner, the load line voltage is equal to the power line voltage, phase voltage is equal to the line voltage. At the same time using the star, the load line voltage is equal to the power line voltage, the load phase voltage is equal to the power phase voltage, phase voltage equal to the line voltage divided by the root number three.
In terms of popularity, the lap is a kind of overlapping, overlapping with each other interface method; and seam law is not overlapping, the use of docking method, will inevitably leave the gap, so called seam method. These two methods are used for geotextile construction, the construction requirements: When the use of lap connection, lap length should be 0.3 ~ 0.9m, the use of seam method, the bonding width of not less than 50mm, bonding strength of not less than The tensile strength of the material. On-site construction of the upper and lower joints should be staggered, staggered length of not less than 0.5m.
