Description

technical field [0001] The invention belongs to the technical field of power connection, and in particular relates to a portable AC power connection device. Background technique [0002] At present, under the working conditions of power relay protection debugging power supply, mobile test power supply, calibration power supply, low-voltage temporary power supply connection device, etc., especially for relay protection debugging of newly installed transformers in customer power distribution rooms, low-voltage power supplies used in high-voltage equipment withstand voltage tests, Most of the connection devices used in low-voltage temporary power connection devices use ordinary boxes, which need to be opened manually, and then manually closed and locked after use. The operation is more troublesome, and sometimes the lock is forgotten, resulting in When carrying or moving the box, if the box cover is suddenly opened, the structure of components may be damaged. In addition, there...

Problems solved by technology

[0002] At present, under the working conditions of power relay protection debugging power supply, mobile test power supply, calibration power supply, low-voltage temporary power supply connection device, etc., especially for relay protection debugging of newly installed transformers in customer power distribution rooms, low-voltage power supplies used in high-voltage equipment withstand voltage tests, Most of the connection devices used in low-voltage temporary power connection devices use ordinary boxes, which need to be opened manually, and then manually closed and locked after use. The operation is more troublesome, and sometimes the lock is forgotten, resulting in When carrying or moving the box, if the box cover is suddenly opened, the structure of components may be damaged. In addition, there are unsafe factors such as exposed live terminals and insufficient insulation, which seriously affect the personal safety of the staff; therefore, provide a A portable AC power connection device with simple structure, high degree of automation, embedded installation and good safety is very necessary
