The invention discloses a mistaken touch prevention isolation device for a secondary wiring terminal strip in a control and protection screen of a transformer substation, relates to the mistaken touch prevention isolation device for the secondary wiring terminal strip, and solves the problems of low safety measure arrangement efficiency and poor reliability of the existing control and protection screen of the transformer substation. An outer-layer shell is a rectangular groove with an opening in one end, an inner-layer shell is a rectangular groove with openings in the two ends, a plurality of fixing holes are formed in the two side walls of the outer-layer shell and the two side walls of the inner-layer shell at equal intervals, and the intervals of the fixing holes in the side walls of the outer-layer shell are equal to the intervals of the fixing holes in the side walls of the inner-layer shell; the inner-layer shell is inserted into the outer-layer shell, the direction of the groove bottom of the outer-layer shell is the same as that of the groove bottom of the inner-layer shell, and safety warning mark stickers are fixed to the outer sides of the groove bottoms of the outer-layer shell and the inner-layer shell. The mistaken touch prevention isolation device is suitable for mistaken touch prevention isolation for the secondary wiring terminal strip in the control and protection screen of the transformer substation.
Description
technical field [0001] The invention relates to an anti-mistouch isolation device for a secondary wiring terminal row. Background technique [0002] At present, the number of electrical equipment in the power system is increasing, and there are a large number of secondary control and protection screen cabinets, multiple secondary equipment at different intervals and multi-segment terminal blocks in the same control and protection screen cabinet. At present, the known arrangement of secondary measures inside the substation control and protection screen are all temporary measures, that is, the red cloth curtain with the word "in operation" is used to cover the operation equipment and the maintenance equipment. The role of warning maintenance operators. [0003] There are two ways to fix the arrangement of the secondary measures inside the substation control and protection screen: one is to use magnets to absorb, and the other is to stick with tape. However, these two fixing ...
