Description

Switch module safety device

Technical Field

Background

According to the regulation of 6.5.1 in the national standard new safety regulation (GB 26860-2011): 'on the isolating switch operating handle which can send power to the working place once being switched on, should hang' switching-on forbidding, someone works! 'OR' forbids closing the switch, the line is operated by people! The 'sign board' so in some power failure work, the air switch needs to be disconnected and set up corresponding sign board. In the safety measure arrangement of the existing transformer substation (converter station), a 15 cm-15 cm 'closing prohibition and somebody works' aluminum signboard is usually used, and a thick cotton line or a nylon line is used for hanging after holes are punched at the left and right corners of the upper end of the signboard. This scheme has several drawbacks: firstly, the aluminum nameplate is made of metal materials and has conductive performance, most of the air switches are positioned on the front and the back of various terminal boxes, mechanism boxes or secondary screen cabinets, the number of connectors is large, and if the air switches are blown or shake and fall caused by working reasons, short circuit is easily caused to damage equipment or trip; secondly, the installation places of the air switch are more narrow, the surface of the air switch and the surface of equipment fixed by the air switch are generally smooth, and the traditional nameplate is difficult to hang in size and in a hanging manner; and thirdly, even if the air switch or the surrounding box body can be hung through a rope, the air switch is easy to shield when the position of the air switch is observed, and meanwhile, the risk of misoperation of the air switch or the adjacent air switch is also generated.

Therefore, it is necessary to design a new air switch safety device, which can be applied to single-phase, two-phase and three-phase air switches of transformer stations (converter stations) of various voltage classes, based on the requirements of the new safety regulations in the national standards and the difficulties and risks caused by the above three problems.
