Description

Technical Field

[0001] The utility model relates to the technical field of lightning arresters, and in particular to a single lightning arrester and a mounting bracket. Background Art

[0002] A single lightning arrester is an electrical appliance used to protect electrical equipment from high transient overvoltage hazards during lightning strikes, and to limit the follow-on time, and often also limit the follow-on amplitude. A lightning arrester is sometimes also called an overvoltage protector or overvoltage limiter. A single lightning arrester is connected between the cable and the earth, usually in parallel with the protected equipment. A single lightning arrester can effectively protect communication equipment. Once abnormal voltage occurs, the single lightning arrester will operate to provide protection. When the communication cable or equipment is operating at normal operating voltage, the single lightning arrester will not work and will be considered a short circuit to the ground.

[0003] Single lightning arresters are generally installed at a higher position outdoors through a mounting bracket. However, since single lightning arresters are installed through only one bracket and are at a high altitude, when encountering harsh environments, such as windy and rainy weather, the one-way lightning arrester is easily affected by the strong wind and caused damage. Therefore, an operator is required to repair it. However, when the operator inspects it, he needs to climb to a high altitude to repair the one-way lightning arrester. The operator is more dangerous when working at high altitude, and maintenance is more inconvenient, which not only affects the maintenance efficiency, but also easily causes harm to the operator.
