Abstract

The invention discloses a multi-stage recoil and solid-phase arc extinguishing dual arc extinguishing device, and belongs to the technical field of arc extinguishing and lightning protection. The device comprises a first arc extinguishing cylinder, a second arc extinguishing cylinder, a third arc extinguishing cylinder, a fourth arc extinguishing cylinder, a solid-phase arc extinguishing body and arc extinguishing cylinders; the arc extinguishing cylinders are arranged on the solid-phase arc extinguishing body, the first arc extinguishing cylinder is arranged on the side edge of the front end of the arc extinguishing cylinder, the second arc extinguishing cylinder is obliquely arranged in the middle of the arc extinguishing cylinder, a recoil opening of the second arc extinguishing cylinder is communicated with the interior of the arc extinguishing cylinder, a lightning receiving electrode of the first arc extinguishing cylinder is connected into the arc extinguishing cylinder, the third arc extinguishing cylinder and the fourth arc extinguishing cylinder are arranged on the side edge of the solid-phase arc extinguishing body in parallel, an opening of the third arc extinguishing cylinder is arranged downwards, and an opening of the fourth arc extinguishing cylinder is arranged upwards. The third arc extinguishing cylinder and the fourth arc extinguishing cylinder are connected through a wire, an electrode is arranged above the fourth arc extinguishing cylinder, and the electrode is connected with an induction device of the solid-phase arc extinguishing body. According to the invention, the intensity of current entering the device can be attenuated, the tolerance level of the device is improved, and the safety is improved.

Description

technical field [0001] The invention relates to the technical field of arc extinguishing and lightning protection, in particular to a double arc extinguishing device with multi-stage recoil and solid phase arc extinguishing. Background technique [0002] Lightning is one of the ways nature releases enormous energy. When the lightning directly hits the line or the tower, a huge lightning current will be generated. If the lightning current cannot be released from the line in time, the power grid will be damaged. At present, the protection of lightning lines and towers mainly includes the installation of lightning conductors and lightning arresters. However, both the lightning conductor and the lightning arrester have certain problems. Using the strike distance method to calculate, there will be a part of the protection area between the lightning protection line and the ground. When the lightning strike occurs in this blank part, the possibility of directly hitting the line w...
