Transformation and application of KYN type switchgear anti misoperation locking device

With the continuous expansion and strengthening of power grid construction, handcart switchgear is becoming more and more popular and applied. KYN type switchgear, also known as armored movable metal enclosed switchgear (referred to as handcart switchgear), has been widely used in power systems due to its compact and reasonable structure, convenient maintenance, simple operation, and high operational reliability. However, in practical applications, it has been found that this type itself has design flaws and certain security risks
In recent years, safety accidents have occurred frequently inside KYN type switchgear, such as the "3.17" personal injury accident of Hefei Power Supply Company and the "8.19" personal injury accident of Jiangxi Gandongbei Power Supply Company, which have exposed the safety hazards of such switchgear equipment
