We all know that the principle of lightning discharge is that it may be between the clouds or the inside of the clouds, and sometimes it happens in the clouds and
And the earth, and many of the large-capacity electrical equipment on the ground will bring a lot of internal surges during use, because
Electrical lightning strikes and damage to power supply systems and damage to equipment, especially power supply equipment, caused by surges have become a concern for lightning protection and
The focus of anti-surge protection is up.
To understand the protection of the surge protector from the power supply, we must first understand the impact of the surge in the power supply system.
External lightning causes and internal electrical equipment start-stop and failure are the main sources of power system surges:
The direct effects of lightning strikes and indirect lightning strikes on lightning strikes to ground are on our low voltage power supply system. Direct lightning strike refers to the thunder
During the process of electric discharge, it directly hits the equipment of our power supply system. Once it is hit, it will inject a large pulse current, causing the design.
The damage is prepared, but the probability of this time is relatively low.
Indirect lightning strike means that lightning strikes directly near the power supply equipment during the discharge process, and the same level of current and electricity is sensed on the power line.
Pressure, the probability of such an event occurring is relatively large.
Then the occurrence of internal surges has a considerable relationship with the start and stop of equipment components in the power supply equipment and the faults during operation. because
The start and stop of high-power equipment and the fault of the line operation are also the operation of the frequency conversion equipment is caused to the inside of the power supply system.
The main cause of the surge is that these internal surges will have a significant adverse impact on the use of electrical equipment. Especially in the fields of computers and communications.
It can cause fatal damage. Http://
