Abstract

The invention discloses a lightning arrester and a lightning arresting method. The lightning arrester comprises a discharge needle, a leading down rod, a protective cover, a capacitor group string, adischarge gap insulator and a protective cover insulator. The lower ends of the capacitor group string, the discharge gap insulator, and the discharge needle and the upper end of the leading down rodare arranged in the protective cover connected with the discharge needle; and the protective cover and the leading down rod are connected by the protective cover insulator. The discharge gap insulatoris connected to the discharge needle and the leading down rod; and a discharge gap is formed among the discharge gap insulator, the leading down rod, and the discharge needle; and the capacitor groupstring is connected with the discharge needle and the leading down rod. After lightning arresting of the discharge needle, the capacitor group string is charged; when the capacitor group string is charged to reach a predetermined voltage, the discharge gap is punctured and discharged; the current flows through the discharge needle and the discharge gap and reaches the leading down rod and then the current flows to the ground through the leading down wire. Therefore, the influence of the mounting height of the lightning arrester can be reduced during the leader discharge process; the lightningarresting time of the lightning arrester is promoted; and the protection range of the lightning arrester is increased.

Description

technical field [0001] The invention relates to the field of lightning protection technology. Background technique [0002] The existing commonly used air-termination devices are generally installed on the top of objects such as the top of buildings or iron towers. Because the installation height of the air-termination devices will be very high, some will be tens of meters, and some will reach the above number. Therefore, when the lightning is triggered and the lightning is received, the distance to the ground loop can reach more than tens of meters. The line impedance of the line from the tip of the air-termination device to the ground will have an adverse effect on the discharge of the air-termination device, and will affect the effect of the air-termination device. The main performance is very important, which is to increase the impedance of the discharge circuit, so that the lightning discharge voltage increases, the lightning receiving time is delayed, and the protecti...
