Description

Technical Field

[0001] The utility model relates to a protection device technology, in particular to an anti-electric shock protection device for a switch of a power substation. Background Art

[0002] The power substation is a key node between the transmission of electric energy from the power plant to the user. It is mainly used to transform voltage, control current and ensure the stable operation of the power grid. Substations usually include transformers, switchgear, protection devices, power electronic equipment, and monitoring and control systems. These devices work in coordination to transform high-voltage electric energy into low-voltage electric energy suitable for transmission and use, while ensuring the safe and stable operation of the power grid. When operators are operating, inspecting and maintaining switchgear, substation switch anti-electric shock protection devices are usually used to protect operators from the risk of electric shock.

[0003] A Chinese utility model patent with publication number CN220585809U discloses an anti-electric shock protection device for a power substation switch. The anti-electric shock protection device for a power substation switch can drive one end of a rotating plate to move downward by pulling a control line, so that the rotating plate can rotate around a rotating axis. The other end of the rotating plate can be driven to move upward through the principle of a lever, and then the switch knob can be driven to rotate upward, so that the protector is switched from the disconnected state to the connected state. Moreover, the length of the control line can be increased or decreased in time according to the installation height of the distribution box, so that it can be suitable for protectors of different heights.

[0004] When the existing power substation switch anti-electric shock protection device is in use, the protector can only be switched from the off-circuit state to the on-state through the control line. When encountering a protector switch installed at a higher position, if you want to switch the protector from the on-state to the off-circuit state, you need to climb up with tools to manually turn the switch to change the protector state, which poses certain safety hazards.
