Three phase power IT system Surge protector Lightning arrester
Product introduction
The product is a surge protector for the plug type low-voltage distribution system, including the replaceable element, and the voltage limiting element is made up of a metal oxide varistor in parallel. Each varistor requires an independent disconnector. The principle of the disconnector is a heat release. The function is disconnected through the low temperature welding point and is separated from the metal rod by its own elastic action. After disengagement, the red guide will appear in the transparent window on the front side of the surge protector.
Product specification
1. Max continuous operating voltage(UC):420V
2. Voltage protective level(UP):2.0KV
3. Max discharge current(IMAX):40KA
4. Nominal discharge current(IN):20KA
5. Response time(NS):<25
Product features
1. low output residual pressure to further ensure safety
2. traffic flow to further improve safety
3. the latest arc extinguishing technology is adopted to avoid the fire completely.
4. Adopt temperature control protection circuit and built-in thermal protection.
Notice of product
1. An equipotential connection is established between the Device and the SPD.
2. Needs to carry out the energy coordination of multilevel SPD
3. in order to limit the inductive coupling between the protected part after installation and the part of the unprotected equipment, we need to make some measurements. The mutual inductance can be reduced by the separation of the inductive source and the sacrificial circuit, the selection of the loop angle and the limitation of the closed loop area.
4. generally speaking, it is better to separate the protected conductor from the non protected conductor, and it should be separated from the ground wire. At the same time, in order to avoid transient orthogonal coupling between power cables and communication cables, necessary measurements should be made.
Working principle of product
Surge protector not only can be used to protect the high voltage of the atmosphere, but also to protect the operation of high voltage. If there is a thunderstorm, a high voltage will appear and the electric equipment may be dangerous. At this point, the arrester will play a role to protect the power equipment from damage. The most important function of the arrester is to limit the overvoltage to protect the electrical equipment. Lightning arrester is a device to make the lightning current flow into the earth, so that the electrical equipment does not generate high voltage.
