In the summer, frequent lightning storms are the peak period for sales of our lightning arresters. Since many customers recently asked me about the installation of surge protectors and lightning arresters , I wrote an article about the installation of surge arresters. The details of the "Notes" help you to find out in detail.
1. Wiring direction <br> <br> lightning protection installation, be sure to pay attention to the input terminal IN and the output terminal OUT, do not reversed, otherwise, it will seriously affect the lightning effect, and even affect normal operation. The input end of the lightning protector is relative to the propagation direction of the lightning wave, ie, the input end of the feeder, and the output end is connected to the protected device.
2. There wiring <br> <br> two kinds of series and parallel wiring, terminal wiring was generally only in series connection, and other coupling methods are used, particularly to the manufacturer's control.
3. The ground connection <br> <br> grounding cable lengths as short as possible, directly to the terminal crimped to an end of the mine, a ground line connected to independent grounding grid (isolated from ground and collector) or three phase power supply The ground line is connected.
4. The mounting position <br> <br> SPD should be installed indoors. At the same time, note that there are no flammable and explosive materials attached to the lightning protection device, such as oil depots (stations), gas storages (stations), fireworks, etc., to prevent sparks from causing fire.
The off operation must be disconnected when <br> <br> installed power, the charging operation is prohibited before the operation table must be tested using a universal bus segment or whether each terminal is completely powered off, off and on again determined wiring.
6. rail mounting <br> <br> mine mounted on the rail, and the first open space mine card in the rail, the rear space and the mine opening securely against the fixed clamp fixed, mounted The lightning protection device on the screen panel must use screws to secure the four corners of the lightning protection device. The screw holes must be placed on the mats. Pay attention to the positive and negative directions of the lightning protection device and the air-opening device, and follow the rules of the upper and the lower.
7 Check the wiring Check wiring <br> <br> out there did not touch together, we have touched together immediately for processing, in order to avoid the occurrence of a short circuit equipment, etc.
8. <br> <br> mine equipment maintenance without special maintenance, just regularly check for loose connections, working status indicator is normal.
When the working status indicator glows green, it indicates that the surge protector is working properly. When it glows red, it indicates that the lightning protection device has been damaged and the lightning protection effect has deteriorated and must be replaced immediately.
