In the major power supply tasks such as the annual high school entrance examination, college entrance examination, and important government meetings, the power sector may face sudden emergency power outages. At this time, it is necessary to ensure that the power supply personnel quickly connect the outgoing cable of the generator to the low-voltage side outgoing line of the user's power distribution room to supply power to the generator.

At present, the conventional emergency generator cable joints have the following problems in the process of connecting the low-voltage side outlets of the user's power distribution room: 1. During the connection process, it is necessary to remove and install the nuts of the low-voltage side circuit breaker studs. The time is long, and the efficiency of emergency power supply is not high. 2. The distance between the pile heads of the low-voltage side circuit breaker is small, and it is very difficult and inconvenient to operate with tools such as wrench and pliers. 3. When the nut of the pile head cannot be screwed or slips, it will seriously affect the timeliness of emergency power supply. 4. During the connection process, the power supply personnel need to directly touch the equipment with their skin, which invisibly increases the risk of electric shock for the power supply personnel.
