The street lamp distribution box is an important accessory of modern street lamps. It is installed inside the lamp pole near the bottom of the street lamp. First, the mains power is distributed to the light-emitting source on the upper part of the light pole, and at the same time, it can be connected to the next street light, so that each street light and the light-emitting source on each street light can be connected in parallel.
1. The street light distribution boxes on the market are mainly divided into two types: one is an air switch type, and the other is a fuse type. As the name implies, the air switch-type distribution box uses the protection component inside the air switch; and the fuse-type distribution box uses the current fuse as the protection component, but it is not an ordinary glass tube fuse, but a current fuse. Ceramic tube fuse;
2. At present, the mains used in China, Europe and most parts of the world is divided into 220 volts and 380 volts, of which 380 volts is three-phase electricity; while the US standard is 120 volts and 277 volts, of which 277 volts is the US standard industrial electricity The voltage value of electricity;
3. No matter whether the mains is 220 volts or 120 volts, the voltage of the luminous source on the upper part of each street light pole after being connected to the power distribution box is still 220 volts or 120 volts; when connected to the next street light The voltage is still 220 volts or 120 volts;
4. If the mains power is 380 volts or 277 volts, the voltage of the luminous source on the upper part of each street light pole is 220 volts and 120 volts respectively after being connected to the power distribution box and then connected to the next street light. The voltage remains the same, or 380 volts or 277 volts, respectively;
5. There are currently two types of street lamp safety distribution boxes developed and produced by Shenzhen Greenway Electronics Co., Ltd.: one of the models is M695, and the matching protection components are ceramic tube current fuses; the other model is M696 , the matching protection component is an air switch;
6. Compared with similar foreign products, the street lamp safety distribution box produced by Shenzhen Greenway Electronics Co., Ltd. has a unique advantage:
That is, in the interior of the street light safety distribution box, you can also use the safety lightning protection device at the same time, which is not available in similar products of other companies on the market!
7. The safety lightning arrester used in the power distribution box of the safety street light is also developed and produced by Shenzhen Greenway Electronics Co., Ltd. The model is M999 series, which has obtained the safety certification of German TUV, and the safety certification of other countries and regions. Security certification is in the process of forensics;
