street light pole set outside, when the rainy days when lightning occurs inevitably, lightning is a big threat. If it is a light, street light can damage, fire and casualties will cause huge losses.

1。 External lightning protection combined with internal lightning protection: the conventional street lamp light pole outside the conductor material, the same as the lightning rod itself. Must set down lead and grounding network, in the design of external lightning protection system. The system can prevent the street light the fire and life safety accidents caused by direct lightning stroke. Internal lightning protection system, refers to the street lamp internal earthing, to keep the maintenance of facilities system in the form of voltage.

2。 Lightning protection, equipotential connection to thoroughly solve the destructive potential difference caused by lightning, will the power cord, signal lines, metal tube and over-voltage protector 【 Over-voltage protector is one of the limit over-voltage of lightning overvoltage and operating the advanced protection of electrical appliances. 】 Connection and the local equipotential connection interface of the reserve, and its local equipotential connection 【 Bonding ( Also called connection) There are several definitions. 】 Parts are connected with total equipotential connection, etc.

3。 The minefield Settings: now in addition to the power supply facilities, also set a number of communications facilities, control of street lamp switch and brightness. These facilities and power must be installed minefield, directly in the paddock enclosure shielding.
