Description

Technical Field

[0001] The utility model relates to an electrical switch, in particular to a three-position switch with a C-GIS high-conductivity aluminum structure. Background Art

[0002] With the economic development and urbanization process, the miniaturization of medium-voltage switchgear is becoming more and more important. The medium-voltage gas-insulated switchgear has a great advantage in volume compared with the air-insulated switchgear. When miniaturizing, due to the limited space inside the cabinet, the requirements for insulation design inside the cabinet are also getting higher and higher. A three-position switch is required to be used inside electrical equipment, and the three-position switch can be used to operate well inside the electrical equipment, making the electrical equipment safer when the three-position switch is operating.

[0003] In the prior art: CN201820875875.X is a device for judging the position state of a three-position switch. The utility model relates to a device for judging the position state of a three-position switch. The three-position switch includes three in-place plates, which are arranged in parallel. A first protrusion extending upward is provided in the middle of the in-place plate, and a second protrusion extending upward is provided at the right end of the in-place plate; it includes an indicating wheel, a microswitch and an indicator light. The number of microswitches and indicator lights is three. The microswitches are fixed on the mounting plate of the three-position switch. The indicating wheel is mounted on the mounting plate of the three-position switch through a wheel shaft. The indicating wheel rotates around the center line where the wheel shaft is located. Grooves corresponding to the first protrusions on the three in-place plates are respectively provided on the wheel surface of the indicating wheel. This device for judging the position state of a three-position switch visualizes and expresses the position states of the three-position switch by using indicator lights.

[0004] Although the three-position switch in the prior art allows users to read the actual position state of the three-position switch through indicator lights and make mutual judgments with the original mechanical indication, making the judgment result more reliable, the three-position switch in the prior art has the problem of inconvenient assembly with other driving devices.
