Power system relay protection worker training device

 

This device organically combines all kinds of power, instruments, loads, simulation circuit breakers, fault setting modules and other organic ways, which are complete. Users can complete all tr--ning and assessment items without buying other accessories. The device covers a small area and saves rooms. There are voltage leakage protectors and current leakage protectors. The power supply output has monitoring and short -circuit protection functions to ensure the safety of operators and equipment. The control screen also has a timer and alarm recorder to provide unified standards for students' skill assessment.

1. Product introduction

Intelligent manufacturing is the m--n direction of building a strong country. CNC machine tools are an important part of intelligent manufacturing. In response to the national call, the company introduced the world's advanced CNC software technology to develop this series of CNC machine tools virtual and real tr--ning machines. The tr--ning machine is combined by software and hardware. The functional is advanced, the quality is reliable, and the CNC system can be diversified.

At present, this type of products include: FANUC 0I-TF Plus (turning version), FANUC 0I-MF Plus (three-axis milling); Mitsubishi series Mitsubishi M80 (three-axis milling version); Siemens series Sinumeik 828D (turning version ), (Three -axis milling version), Sinumerik 840d (five -axis milling version); Hydehan series (five -axis milling version).

2. Product characteristics

The five -axis and five linkage CNC processing center is currently a CNC machine tool with high -end and complex processing procedures on the market. Programmers and operators also require very professional personnel to be competent. It is a high -precision CNC machine tool, which causes the school to be unable to purchase a large number of purchases and cause students to be unable to tr--n normally.

At present, professional teachers can only expl--n in the classroom through textbooks. Students do not have the cognition and experience of real machine tools during their learning. If they directly take students to real machine tool tr--ning, students will cause great psychological pressure. The actual factors such as the loss of the collision, the material and the tool, the machine tools are prone to damage, the unsafe, and the high teaching cost.

In order to solve the above factors, our company has developed the latest generation of one -machine five -axis CNC processing center virtual and real tr--ning machine. This device is combined by software and hardware. It has the functions of programming, processing, and debugging. The simulation operation of the interchangeable five -axis CNC machining center can be manually programmed or entered the CAD/CAM program for simulation processing. Highly simulating software CNC system interface is the same as the real CNC system. It is equipped with a real operating panel and hand wheel, so that students can experience the consistent operation experience of the real CNC machine tools during the learning process. Special design. The m--n body hardware of the device consists of four parts.

1. Five -axis CNC processing center virtual reality and reality tr--ning machine cabinets adopt a vertical structure that conforms to the real CNC machine tool operation experience. The cabinet is bent and welded by high -strength steel plates. 4,000 -way pulleys and configure the brake device to facilitate movement and fixation.
