Description

Technical Field

[0001] The utility model relates to the technical field of preventing misoperation of a ring network cabinet, in particular to a device for preventing misoperation of a switch of a ring network cabinet. Background Art

[0002] The ring main unit anti-misoperation device is an important safety device in modern power systems. The in-depth understanding of fault behavior in power systems and the awareness of the risks of misoperation are necessary. There are many factors in power systems that may lead to misoperation, such as human operating errors, equipment failures, external interference, etc. In order to ensure the stable operation and safety of power systems, it is particularly important to develop a ring main unit anti-misoperation device. It is an urgent response to the safety needs of power systems. It is an indispensable and important part of modern power systems. The anti-misoperation switch devices on the market cannot accurately identify the switch status, which may make it difficult for operators to accurately identify the status of the switch, increase the risk of misoperation, and bring potential safety hazards.

[0003] After searching, China Patent Publication (Announcement) No. 202120949688.3 discloses a ring network cabinet anti-switch misoperation device. The patent opens a gate hole in the middle of the protective frame, and slide grooves are opened on both sides above the protective frame. Support rods are vertically installed in the slide grooves, and sliders are integrally formed at both ends of the rear side of the limit frame. The slider is movably installed in the slide groove to prevent the network cabinet from being accidentally touched. Since the switch state cannot be accurately marked in the anti-accidental touch switch device, it is difficult for the operator to accurately identify the state of the switch, which increases the risk of misoperation and brings potential safety hazards. By setting an automatic opening device with an identification plate, the gate that needs to be opened can be determined, and since the fixed position of the switch is unstable due to the different sizes of switches, the position of the device is fixed by sliding a positioning block, so that the device can be flexibly fixed. Therefore, it is necessary to design a ring network cabinet anti-switch misoperation device. Utility Model Content
