DYKGG-5 electrical installation and maintenance assessment training platform

1. Equipment usage and characteristics:

The electrical installation and m*ntenance tr*ning and assessment device is a general tr*ning platform developed based on the tr*ning and qualification requirements for m*ntenance electricians and electrical installers in factory electrical installation and indoor electrical installation . It is suitable for use as a public tr*ning platform for m*ntenance electricians , electrical installers, plumbers and other related majors with electrical tr*ning requirements in various vocational colleges and technical schools .

The device is made of steel mesh plates and aluminum alloy frames, and is equipped with self-locking casters for easy movement and use. The design height of the device is such that it can be easily operated by a person standing on a step ladder, which is both safe and allows users to feel the construction site environment. The transverse and cluster widths are appropriate and can simulate the steering layout of on-site lines. The mesh plate can be easily removed. When constructing concealed projects, the aluminum alloy frame is carefully designed to imitate the enlarged width of the keel used for building partitions. It is equipped with pipe holes, and cable ties are used to fix the wire pipes. When passing through the mesh plate, you can use wall spacing to lead out the wires. Exposed bottom box. The matching PVC pipe bender can easily bend PVC pipes to 90 degrees.

Can be installed by electrician. Such as bridge installation, PVC pipe installation, chandeliers, incandescent lamp holders, fluorescent lamps, switches, sockets, control boxes, distribution boxes, etc., including AC asynchronous motors, DC motors, stepper motors , servo motors, temperature controllers, galvanic couples , plc , inverter touch screen and other control and controlled objects. Each operation group is equipped with a movable tool cart and component cabinet to facilitate the storage and installation of components. It fundamentally solves the problems of inconvenient use and narrow scope of practical tr*ning for school installation tr*ning on ordinary walls.

The equipment should be flexible and convenient to assemble. It can be composed according to the actual teaching conditions of the school, in groups of 2, 3, 4..., single-sided, double-sided, etc. The length combination is based on two 0.8-meter basic combination units, supplemented by 0.2-meter and 0.4-meter combination units, forming different length combinations to meet the needs of different teaching venues.

This software can drag the red and black pen tips at will. When the two pen tips are dragged and positioned on the object to be measured, a red circle will be displayed. If the positioning is not accurate, no red circle will be displayed, and when incorrect operations are performed (such as the wrong range selected, If the measured data is wrong, etc.), the meter pointer will be unresponsive, prompting errors and re-measurement, etc. This multimeter can select AC voltage range, DC voltage range, resistance range, current range, resistance adjustment to 0, and can enlarge the display data.
