Description

Technical Field

[0001] The invention relates to a lightning arrester, in particular to a multi-port communication column type overvoltage protection lightning arrester. Background Art

[0002] Lightning strikes can cause different forms of damage and destruction to power facilities, and thundercloud discharges can cause lightning overvoltage in the power system. Lightning protection for transmission lines has always been an important part of the lightning protection work of the power department. For this, the power department generally adopts the installation of line lightning arresters on the transmission lines to achieve protection. Lightning arresters are often used to protect components of power networks or power equipment from damage by lightning. Lightning arresters are usually connected between the grid conductor and the ground wire. Once abnormal voltage appears in the power system, the lightning arrester will take action and play a protective role. When the communication cable or equipment is running at normal operating voltage, the lightning arrester will not work and is regarded as a circuit breaker for the ground. Once high voltage appears and endangers the insulation of the protected equipment, the lightning arrester will immediately act to direct the high voltage impact current to the ground, thereby limiting the voltage amplitude and protecting the insulation of the communication cables and equipment in the power system.

[0003] Due to structural design problems, existing lightning arresters cannot stably release current to the ground wire when subjected to a large current shock.
