Abstract

The present invention discloses a power braking rod capable of realizing post switch five-protection interlocking, pertaining to the technical field of electric power fittings. The rod comprises a rodbody, a first poking rod and a second poking rod arranged on the rod body. The first poking rod is movably connected with the rod body, and the first poking rod stretches from the rod body. The second poking rod is movably connected with the rod body, and the second poking rod stretches from the rod body. When the rod is used, the first poking rod or the second poking rod stretches from the rod body. According to the rod, the accuracy of operation is improved via the rod body, the first poking rod and the second poking rod.

Description

technical field [0001] The invention relates to the technical field of electric power fittings, in particular to a brake lever for realizing five-proof locking of a switch on a pole. Background technique [0002] The brake lever is an insulating tool used to operate live equipment for a short time, such as turning on or off the high-voltage isolating switch, dropping the fuse, etc. [0003] Pulling lever, also known as insulating operating rod, insulating rod, high-voltage operating rod, commonly known as multi-purpose gram rod, can be divided into 10KV insulating operating rod, 35KV insulating operating rod, 110KV insulating operating rod, 220KV insulating operating rod, 330KV Insulated operating rod, 500KV insulating operating rod. [0004] The insulating operating rod is one of the most commonly used safety tools for grass-roots rural power workers. It is mainly used to stop and send power to rural distribution transformers and line switches. [0005] Existing technical...
