The first two types of resistors in the busbar processing machine are the most widely used, and their damage characteristics are that the damage rates of low resistance (below 100Ω) and high resistance (above 100kΩ) are relatively high, and the intermediate resistance (such as several hundred ohms to tens of thousands of ohms) has a high damage rate. Second, when the low-resistance resistance is damaged, it is often scorched and blackened, which is easy to find, while the high-resistance resistance is rarely damaged. Wirewound resistors are generally used for large current limiting, and the resistance value is not large. When the cylindrical wirewound resistor of the busbar processing machine is burned out, some will turn black or the surface will explode or crack, and some will have no traces. Cement resistors are a type of wirewound resistors, which may break when burned out, otherwise there will be no visible traces. When the fuse resistor burns out, some surfaces will blow off a piece of skin, and some will have no traces, but they will never be scorched and blackened. According to the above characteristics, you can focus on checking the resistance and quickly find the damaged resistance.
The output of the pulse encoder of the busbar processing machine manufacturer is generally two pairs of differential signals A and A, B and B, which can be used for position and speed measurement. Four square waves of A and A, B and B are introduced into the PG card. After the sum is multiplied by the magnification, it becomes the measurement pulse representing the displacement, which is introduced into the high-speed counting terminal of the PLC for position control.
The tension control of the multi-function busbar processing machine and the correction of the foil strip are the key skills of the foil coil winding machine. The foil tension of the existing domestic or imported foil coil winding machine is generated by machine friction, and the tension is insufficient. If it does not change, it will cause defects such as uneven density of wound coils, different DC resistances between coils, and out-of-tolerance coil outer diameters.
The busbar processing machine adopts the relative counting method to measure the position. Before running, store the pulse numbers of each signal, such as the position of the speed change point, the position of the leveling point, the position of the braking stop point, etc., into the corresponding memory unit respectively. During the running process of the elevator, through the rotary encoder Detection, the software calculates the following signals in real time: the floor position of the elevator, the position of the speed change point, and the position of the leveling point.
Busbar processing machine
The busbar processing machine can count the floors, send out the speed change signal and the floor signal line is faulty. The line patrol personnel can quickly determine the faulty section with the help of the alarm display of the indicator, and the busbar processing machine can find the fault point. At the same time, the fault indicator can detect the running status of the line and the location of the fault in real time, such as power transmission, power failure, grounding, short circuit, overcurrent, etc. When the operating status of the line changes, the on-duty personnel and management personnel are quickly informed, and a processing decision can be made quickly, which can greatly improve the reliability of power supply and improve the satisfaction of users. Informatization management of line and equipment operation.
