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 distribute the mains power reasonably: when the mains power cable enters the street lamp from the ground, the mains power is first distributed 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.
At present, the street lamp distribution boxes on the market are mainly divided into two types: one is air switch type, and the other is fuse type. As the name implies, the protective components used in the air switch type distribution box are air switches; The protective components used in the fuse type distribution box are current fuses, but they are not ordinary glass tube fuses, but ceramic tube fuses;
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; And the American standard is 120 V and 277 V, of which 277 V is the voltage value of the American standard industrial power;
Whether the mains power is 220 V or 120 V, the voltage that is 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; And the voltage connected to the next street lamp is still 220 V or 120 V;
If the mains power is 380 V or 277 V, the voltage that is connected to the distribution box and then distributed to the light source on the upper part of each street lamp pole is 220 V and 120 V respectively; And the voltage connected to the next street lamp remains unchanged, 380 V or 277 V respectively;
At present, there are two types of street lamp safety distribution boxes developed and produced by Shenzhen greenway Electronics Co., Ltd.: one type is m695, and the matching protection components are ceramic tube current fuses; Another model is m696, and the matching protective component is an air switch;
Compared with similar products abroad, 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 protector can also be used at the same time, which is not available in similar products of other companies in the market at present!
The safety lightning protector used inside the matching safety street lamp distribution box is also developed and produced by Shenzhen greenway Electronics Co., Ltd. and the model is m999 series. At present, it has obtained the safety certification of TUV in Germany, and the safety certification of other countries and regions is in the process of obtaining certificates;
A lightning protector is also installed in the street lamp distribution box, which can more effectively ensure the safety of street lamps when they are struck by lightning!
