What is a street light safety distribution box?

2023-12-02

The street lamp distribution box is an important accessory of modern street lamps. It is installed inside the lamp post near the bottom of the street lamp, and its function is to distribute the mains power reasonably: when the mains power cable enters the street lamp from underground, it is first distributed to the luminous source on the upper part of the lamp post, and can also be connected to the next street lamp, so that each street lamp and the luminous source on each street lamp can be in a parallel circuit connection state.

1. The street light distribution boxes on the market are currently mainly divided into two types: one is air switch type, and the other is fuse type. As the name suggests, the protective components used inside an air switch type distribution box are air switches; The protective components used in fuse type distribution boxes are current fuses, which are not ordinary glass tube fuses, but ceramic tube fuses;

2. At present, the mains electricity 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; And the American standard is 120 volts and 277 volts, of which 277 volts is the voltage value of American standard industrial electricity;

3. Regardless of whether the mains power is 220V or 120V, the voltage distributed to the upper light source of each street lamp post after being connected to the distribution box is still 220V or 120V; And the voltage received from the next street light is still 220 volts or 120 volts;

4. If the mains voltage is 380V or 277V, and it is connected to the distribution box and then distributed to the upper light source of each street lamp post, the voltage is 220V and 120V respectively; The voltage received from the next streetlight remains unchanged, at 380 volts or 277 volts respectively;

5. There are currently two types of street light safety distribution boxes developed and produced by Shenzhen Greenway Electronics Co., Ltd. One of them is M695, and the matching protective component is a ceramic tube current fuse; The other model is M696, which is matched with an air switch as aprotective component;

6. Compared with similar foreign products, the street light safety distribution box produced by Shenzhen Greenway Electronics Co., Ltd. has a unique advantage:

That is to say, inside the safety distribution box of the street light, safety lightning arresters can also be used simultaneously, which is not available in similar products of other companies on the market at present!

7.The safety lightning arrester used inside the matching safety street light distribution box is also developed and produced by Shenzhen Greenway Electronics Co., Ltd. The model is M999 series and has obtained safety certification from TUV in Germany. Safety certification from other countries and regions is currently being obtained.
