How to choose Distribution Transformer?

The Key Selection points of Oil-Immersed Distribution Transformer . Load Properties of Distribution Transformer: 1) When there are a large number of primary or secondary loads, it is advisable to install two or more transformers. When one transformer is disconnected, the capacity of the remaining transformers can meet the demand of primary and secondary loads. First, the secondary loads should be concentrated as far as possible and should not be too dispersed. 2) When seasonal load capacity is large, special transformer should be installed. For example, in large civil buildings, the load of air conditioning refrigerators, heating electricity and heat, etc. 3) When the concentrated load is large, special transformer should be installed. Such as large heating equipment, large X-ray machine, electric arc furnace, etc. 4) When the lighting load is large or the power and lighting use common transformer seriously affects the lighting quality and lamp life, special lighting tra

CNC MACHINE TOOL CLASSIFIED AS PER THE CONTROL TRACK MOVEMENT

Classification according to the control track of CNC machine tool movement. (1) CNC machine tool controlled by point and position Point position control requires to control the moving parts to move from one point to another for accurate positioning. The requirements for the motion track between points are not strict. In the process of moving, there is no processing, and the motion between the coordinate axes is irrelevant. In order to achieve fast and accurate positioning, the movement of displacement between two points generally moves fast first. And then approaches the positioning point slowly to ensure the positioning accuracy. As shown below, which is the motion track controlled by the point position. point position control motion track The machine tools with point control function mainly include CNC drilling machine, CNC milling machine, CNC punch, etc. With the development of numerical control technology, there are few numerical control systems which are only used for po
