Description

Technical Field

[0001] This utility model relates to the field of protection device technology, specifically a power outage protection device for power supply switch maintenance. Background Technology

[0002] In industries such as coal, electricity, construction, and petroleum, multi-level power supply switches are widely used in their power systems. When electrical professionals inspect these switches, they follow operating procedures to de-energize them from top to bottom, prioritizing branch switches over main switches and low-voltage switches over high-voltage switches. They first disconnect the power supply to the upstream switch, display a power outage sign, or assign a dedicated person to monitor the switch before proceeding to the downstream switch for inspection. Only after completing the inspection do they reopen the upstream switch. Using power outage signs could lead to unauthorized energization of the upstream switch, causing safety accidents. While assigning a dedicated person to monitor the switch effectively prevents accidents, it is more cumbersome, labor-intensive, and less efficient.

[0003] Chinese utility model patent application CN213585142U discloses a power-off protection device for power switch maintenance, including an upper-level power switch and a lower-level power switch connected in series on a power supply cable. The lower-level power switch is equipped with an open-cover detection module, which is connected to a lower-level control module. A power-off control module is connected between the upper-level and lower-level power switches, and the power-off control module is connected to the upper-level control module, which is communicatively connected to the lower-level control module. When the open-cover detection module detects an open-cover signal from the lower-level power switch, the upper-level control module controls the power-off control module to cut off the power to the lower-level power switch. This utility model is simple to operate, can improve the work efficiency of maintenance personnel, and can prevent safety accidents caused to maintenance personnel due to negligence by electrical professionals or forced power supply from the upper-level power switch, effectively protecting the work safety of maintenance personnel. However, this device does not solve the problem of inconvenience in providing power-off protection for power switch maintenance. Therefore, we propose a power-off protection device for power switch maintenance. Utility Model Content
