Abstract

The invention discloses a visible bypass load switch comprising a housing, a handle, three first electrical connectors, a second electrical connector, a main shaft and a conductive frame. The three first electrical connectors are orderly arranged on one side plate of the housing from bottom to top, a user can rotate a handle outside the housing, the handle drives the main shaft to rotate, so thatthe conductive frame and a first conductive contact and a second conductive contact are disconnected or connected, the housing is filled with an inert gas to realize safe opening and closing of three-phase high-voltage power. Meanwhile, a user can confirm whether a switch is switched on or off through an observation port, only one observation port is set in the invention and just faces one first conductive contact or second conductive contact, the area of an opening is reduced, and the sealing performance of the whole body of the housing is improved.

Description

technical field [0001] The invention relates to a bypass load switch, in particular to a visual bypass load switch. Background technique [0002] The traditionally used bypass load switch has no visible window for the switch contact, and the user cannot confirm whether the switch is really opened or closed. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned technical deficiencies, provide a visual bypass load switch, and solve the technical problem in the prior art that the bypass load switch has no visible window for the switch contact and cannot confirm whether the switch is on or off. [0004] In order to achieve the above technical objectives, the technical solution of the present invention provides a visual bypass load switch, which is characterized in that it includes: a housing, a handle, a first electrical connector, a second electrical connector, a main shaft, and a conductive frame. There are three electric...
