PGL1, 2 AC low-voltage distribution panel has the advantages of reasonable structure, safe circuit configuration, good protection performance, high breaking capacity, good dynamic and thermal stability, safe and reliable operation, etc., and is a new generation of low-voltage switchgear and the preferred product for power grid transformation. Each main circuit scheme of this product corresponds to one or several auxiliary circuit schemes. After selecting the main circuit scheme, the user can easily select the appropriate electrical schematic diagram from the corresponding auxiliary circuit scheme, thereby reducing the user's design workload and improving work efficiency; The multi-circuit small motor control scheme is eliminated, and the main circuit scheme is more concise and reasonable. For the control scheme of multi-circuit small motor, it is recommended to choose the power box series products; The screen width of this product is pided into four types: 400, 600, 800, 1000mm, each screen can be used as an independent unit, and can also be combined with the screen as a unit into a variety of different schemes, so that users can choose.
Structural features of this product:
1. This product is a low-voltage power distribution device with indoor fixed installation and open double-sided maintenance.
2. Its shell is made of thin steel and angle steel welded combination, there is a door in front of the screen, the dashboard above the screen is an open small door, can be equipped with an indicator instrument, and the assembled screen is bent between the steel plate bent partition, which reduces the possibility of the accident expansion due to the internal failure of a unit (one screen), above the skeleton behind the screen, the main bus bar equipped with a protective cover is installed on the insulation frame, effectively preventing the malignant accident of short circuit of the main bus bar caused by falling metal objects above.
3. On the bottom of the second screen of the neutral busbar setting, there is a protective paint layer inside and outside the shell, and the terminal screen of the beginning screen can be added with a protective plate.
4. This product has a good protective grounding system, the main grounding point is welded under the skeleton, and the instrument door also has a grounding point connected to the shell. This constitutes a complete grounding protection circuit. Due to the reliability of this grounding protection circuit, the protection against electric shock of the operator is greatly enhanced.
