Under the premise of ensuring the normal operation of the equipment, equipment inspection and maintenance are the focus of daily work, especially high-voltage equipment. Because of its relatively high voltage level, the safety requirements are more stringent. In addition to being guarded by a dedicated person after each power outage, it must also be locked. Only under double protection can high-voltage equipment be operated. However, due to the differences in the selection of high-voltage switches and the equipment structures of various manufacturers, the requirements for locking protection cannot be met. Therefore, after a long period of exploration and discussion, this portable locking device was designed, which perfectly solves the need for high-voltage switches to be unable to be locked, and further ensures the safety of maintenance personnel.

[0003] Among them, the publication number "CN209785791U" discloses "a locking device for a mining feeder switch". This locking safety device provides an idea of ​​setting a first lock hole, a locking rod shielding groove, a locking connecting plate and other components from the aspect of increasing the safety of the high-voltage switch, and has high practicality. However, this locking safety device still has certain shortcomings in actual use. Although this locking safety device improves its safety by complicating the unlocking process, general locks are sufficient to ensure the safety of the high-voltage switch. Compared with multiple switch fuses, the use of warnings in the protection of the high-voltage switch is often insufficient. In addition, the existing locking safety devices are generally large in size and different in shape, and are usually inconvenient to carry when in use. For this reason, the utility model provides a high-voltage switch locking safety device. Utility Model Content
