1. Product overview:

 

The device is designed and manufactured according to the standard electrical control cabinet, and the panel structure is adopted. Highlighting skills tr--ning, focusing on targeted, practicality, and scientificity. After the use of various vocational skills tr--ning centers, vocational schools, and technical schools across the country, the cabinet design is reasonable, practical, and occupied with a small area. In order to extend the service life of the electrical appliances, the contacts of each electrical appliance are connected to the wiring terminal, and then the students are connected to the wiring terminal to connect the motor and electrical appliances to complete various control experiments, effectively reduce the material consumption, and extend the service life. This set of equipment is applicable to various labor vocational skills appr--sal departments, while adapting to major, technical secondary school, technical schools, vocational school junior, intermediate electrical engineering, and tr--ning and tr--ning assessment.

 

2. Product characteristics:

 

1. Assessment function: The equipment is equipped with a timer and an accidental operation alarm recorder. It is usually used as a clock. The time can be set during the assessment. Students are required to complete the experimental items within the specified time. Cut off the function of the power. At the same time, it also has the total number of times the power leakage and overcurrent, short -circuit alarm and power supply breaks caused by wiring or operating errors. Provide a unified standard for the assessment of students' experimental skills.

 

2. Safety performance: The device has a current and voltage leakage protection device to ensure personal safety and apply special requirements for students' operations. At the same time, there is an overcurrent or short -circuit protection device to ensure the safety of the equipment. The equipment is input by three -phase and five -line power supply, and the power supply is controlled by the contactor through the start and stop button. There are three -phase voltage table indications. Including a current leakage protector, if there is a leakage of the control screen, the leakage current value exceeds a cert--n value, that is, the power supply is cut off, and the voltage leakage protector is also equipped. , That is, the alarm and make the contactor in the device. Cut off the power supply to ensure personal safety. There is also a set of overcurrent protection devices. The output is short -circuited or the load is too large, and the current exceeds the setting value.

 

3. Reasonable structure: The device is based on the standard power distribution cabinet as the m--n cabinet, and uses the double -sided space of the cabinet to scientifically arrange electrical appliances and supporting experimental equipment. The cabinet design is reasonable and convenient, and the cabinet is used for multiple. All electrical component contacts have been received on the wiring terminal. Students only need to wiring on the wiring terminal to extend the service life of the electrical component and reduce the material loss.

 

4. Beautiful appearance: Reasonable installation layout, beautiful appearance, and clear and intuitive panels. The wiring is clear and tidy, reducing the f--lure link and improvement of reliability. The device adopts the iron double -layer sub -light dense -densely spraying structure; the structure is firm and beautiful. Beautiful and generous product shape, advanced structure and process. It makes people feel pleasing to the eye.
