GE IS200TVIBH2BBB  变压器

无需其他外部跟踪装置,如CMM、便携式测量臂等。

采用便携式设计,具有质量和体积小,具有运输方便的特点,因而不受扫描方向、物件大小及狭窄空间的局限,可实现现场扫描。

扫描过程在PC屏幕上同步呈现3 E维数据,边扫描边调整;通过对定位点的自动拼接,可以做到整体360度扫描一次成型,同时避免漏扫盲区。

直接以三角网格面的形式录入数据,由于没有使用点云重叠分层,避免了对数据模型增加噪音点;而且采用基于表面最优运算法则的技术,因此扫描得越多，数据获取就越精确。

数据输出时，自动生成高品质的STL多边形文件,马上可以读入CAD软件以及快速成型机和一些加工设备;同时兼容多种逆向软件,可以生成文鸡各种CAD格式文件。

所谓涡流探伤是基于电磁感应原理，当把通有交变电流的线圈（激磁线圈）靠近导电物体时，线圈产生的交变磁场会在导电体中感应出涡电流，该涡电流的分布及大小除了与激磁条件有关外，还与导电体本身的电导率、磁导率、导电体的形状与尺寸、导电体与激磁线圈间的距离、导电体表面或近表面缺陷的存在或组织变化等都有密切关系。涡电流本身也要产生交变磁场，通过检测其交变磁场的变化，可以达到对导电体检测的目的。因此，利用涡流探伤技术，可以检测导电物体上的表面和近表面缺陷、涂镀层厚度、热处理质量（如淬火透入深度、硬化层厚度、硬度等）以及材料牌号分选等等。

　　退磁的方法很多:1.将钢材加热到居里温度以上(铁的居里温度为摄氏769度),当然此温度状态下,材料受到热处理,材料的性能会发生改变.2.可以将材料置于交流线圈前,使其缓慢通过交流线圈,直至离开线圈1米以外,对于重型或大型工件,也可以将交流线圈套在工件上,通电时将线圈缓慢通过并远离工件,在距工件1米以外段电.3.直流换向衰减法或频电流自动退磁,也是可以选用的方法.

There is no need for other external tracking devices, such as CMM and portable measuring arm.

Portable design has the characteristics of small mass and volume and convenient transportation, so it is not limited by scanning direction, object size and narrow space and can realize on-site scanning.

During the scanning process, 3 e-dimensional data is presented synchronously on the PC screen, and it is adjusted while scanning; Through the automatic splicing of positioning points, the whole 360-degree scanning can be formed at one time, and the literacy area can be avoided.

Data is entered directly in the form of triangular mesh surface, which avoids adding noise points to the data model because there is no overlapping layering of point clouds. Moreover, the technology based on surface optimal algorithm is adopted, so the more scanning, the more accurate the data acquisition.

When data is output, high-quality STL polygon files are automatically generated, which can be read into CAD software, rapid prototyping machine and some processing equipment immediately; At the same time, it is compatible with a variety of reverse software, and can generate various CAD format files of wenji.

The so-called eddy current flaw detection is based on the principle of electromagnetic induction. When the coil (exciting coil) with alternating current is close to a conductive object, the alternating magnetic field generated by the coil will induce eddy current in the conductor. The distribution and size of the eddy current are closely related to the electrical conductivity and permeability of the conductor itself, the shape and size of the conductor, the distance between the conductor and the exciting coil, and the existence or structural changes of defects on or near the surface of the conductor. The eddy current itself also produces an alternating magnetic field, and the purpose of detecting the conductor can be achieved by detecting the change of its alternating magnetic field. Therefore, eddy current flaw detection technology can be used to detect surface and near-surface defects on conductive objects, coating thickness, heat treatment quality (such as quenching penetration depth, hardened layer thickness, hardness, etc.), material grade sorting and so on.

There are many ways to demagnetize: 1. Heat the steel above the Curie temperature (the Curie temperature of iron is 769 degrees Celsius). Of course, at this temperature, the material will be subjected to heat treatment, and the properties of the material will change. 2. You can put the material in front of the AC coil and make it slowly pass through the AC coil until it is 1 meter away from the coil. For heavy or large workpieces, you can also wrap the AC coil around the workpiece, and slowly pass the coil away from the workpiece when it is energized.
