How to check the working status of the high voltage PDC

Disassemble the power distribution cabinet of the device, check the quantity and specifications according to the design drawings and imitation documents, and check whether the accessories are complete. Number cabinets according to the design drawings. After the PDC is placed on the channel steel, adjust other PDC units by one.

After securing the bolts, secure the cabinet to the channel steel by securing bolts or welding them. The main busbar and meter on the switchboard are provided by the switch factory. The main busbar connection, the connection between the main busbar and the lower busbar, and the connection between the busbar and the instrument are all connected by bolts, which are controlled by tightening the bolts with a torque wrench.

The selection principle of low-voltage distribution box is as follows:

1, the establishment of requirements, according to the specific situation to choose the appropriate distribution box model, which is the basic standard for our selection.

2, it is recommended to choose domestic distribution box and distribution box manufacturer's domestic distribution box cabinet type. Do not blindly follow the trend, choose imported equipment with higher performance parameters, which is easy to cause losses.

3, the key components of the imported distribution box choose well-known brands and the same as the cabinet door. Therefore, it is necessary to pay attention to the technical parameters of the components to ensure that they meet the requirements for use. The pull-out type consists of a fixed cabinet and a moving device part equipped with a switch and other major electrical components. Moving parts should be light when moving, positioning after moving in? Reliable, can reliably replace the same model, specifications of the drawer.
