What is street lamp safety distribution box?

2022-04-15

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. Its role is to reasonably distribute the mains power: when the mains power cable enters the street lamp from the underground, it first distributes the mains power to the light source on the upper part of the lamp pole, and at the same time it can be connected to the next street lamp, so that each street lamp and the light source on each street lamp can be connected in parallel.

1. At present, the street lamp distribution box on the market is mainly divided into two types: one is air switch type and the other is fuse type. As the name suggests, the protective component used in the air switch type distribution box is the air switch; In the fuse type distribution box, the protective component used is the current fuse, but it is not an ordinary glass tube fuse, but a ceramic tube fuse;

2. At present, the commercial power used in China, Europe and most parts of the world is divided into 220 V and 380 V, of which 380 V is three-phase power; The American standard is 120V and 277v, of which 277v is the voltage value of American standard industrial power;

3. Whether the mains power is 220 V or 120 V, the voltage connected to the distribution box and then distributed to the light source on the upper part of each street lamp pole is also 220 V or 120 V; The voltage of the next street lamp is still 220 V or 120 V;

4. If the mains power is 380V or 277v, the voltage connected to the distribution box and then distributed to the light source on the upper part of each street lamp pole is 220V and 120V respectively; The voltage connected to the next street lamp remains unchanged, 380 volts or 277 volts respectively;

5. At present, there are two types of street lamp safety distribution boxes developed and produced by Shenzhen greenway Electronics Co., Ltd.: one model is m695, and the matched protective component is ceramic tube current fuse; The other model is m696, and the matched protective component is 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 lamp safety distribution box, the safety lightning arrester can also be used at the same time, which is not available for similar products of other companies in the market at present!

7. The safety lightning arrester used inside the matching safety street lamp distribution box is also developed and produced by Shenzhen greenway Electronics Co., Ltd. with the model of m999 series. At present, it has obtained the safety certification of TUV in Germany, and the safety certification of other countries and regions is being obtained;
