Problems of Pole Top Box for lighting
As a lighting tool, the Pole Top Box can maintain abnormal overcurrent and play the role of open circuit. It can be internally assembled to complete several control and use of domestic power supply. At the same time, the equipment is also equipped with grounding maintenance, which is convenient to connect the power distribution system. Pay more attention when using. So, what's the problem with the Pole Top Box used for lighting? Now, let's have a look.
Improper use of the Pole Top Box will only increase the defects of the distribution cabinet. The correct use method can reduce the consumption of the distribution cabinet and effectively reduce the heat in the box, so as to prolong the operation time of the equipment and improve its protection. Moreover, the temperature of the Pole Top Box of the lighting lamp is high, and the streamline load is in the same specification, so it cannot be higher. When selecting, select the appropriate size.
Poor handling of the Pole Top Box device will lead to joint burns. This is because the electrician does not press the wire when changing the wire, but uses the method of winding the nose, resulting in wire burning before changing the wire. Some follow the distribution cabinet, but there are problems due to poor heat dissipation effect. When increasing the load, consider increasing the current to control the rated current. If it exceeds the demand, cut off the power supply with air.
Therefore, when installing lightning arresters on the incoming side of the Pole Top Box, the lightning protection area should be well maintained. Generally, the incoming and outgoing lines and buses of the lighting distribution cabinet are equipped with fuses. If the outgoing line is struck by lightning, the fuse will be blown out, and the lightning protection device of the distribution cabinet will lose its function, which is why the distribution cabinet will be damaged every time it is struck by lightning.
