Abstract

The invention discloses a novel SF6 equipment three-way valve state display device. The novel SF6 equipment three-way valve state display device comprises a three-way valve body and a visual adjustingunit, wherein the three-way valve body comprises a first pipeline and a second pipeline, and the first pipeline is perpendicular to the second pipeline; the visual adjusting unit comprises an openingand closing mechanism and a visual mechanism, the opening and closing mechanism comprises a stepped plugging block and a supporting rod arranged on a side end face of the stepped plugging block, andthe stepped plugging block is located in the first pipeline; and the visual adjusting unit further comprises a moving rod connected with the other end of the supporting rod. According to the novel SF6equipment three-way valve state display device, an operation inspector can accurately judge the flow and the opening and closing state of a three-way valve according to an ejector block popped out atthe corresponding position, so that the operation inspector can efficiently, conveniently and accurately judge the state of the three-way valve, the misjudgment risk is eliminated, the inspection time is shortened, the inspection efficiency is improved, and safe operation of equipment can be ensured.

Description

technical field [0001] The invention relates to the field of GIS combined electrical equipment, in particular to a novel SF6 equipment three-way valve state display device. Background technique [0002] When inspecting the opening and closing state of the three-way valve of the existing SF6 equipment, since the opening and closing state of the three-way valve is not easy to judge, it is easy to cause misjudgment of the opening and closing state of the SF6 gas chamber, so that the SF6 density relay cannot normally alarm, resulting in SF6 equipment damage, affecting the reliability of power supply. Contents of the invention [0003] The purpose of this section is to outline some aspects of embodiments of the invention and briefly describe some preferred embodiments. Some simplifications or omissions may be made in this section, as well as in the abstract and titles of this application, to avoid obscuring the purpose of this section, the abstract and titles, and such simplif...
