Description

Shore power box interlocking device Technical Field The utility model belongs to the technical field of a shore power box interlocking device, and particularly relates to a shore power box interlocking device. Background The shore power box is a ship power supply guarantee device specially installed at a port and a dock, and has the advantages of fine design and comprehensive functions. The three-phase alternating current power distribution system is suitable for a three-phase alternating current power distribution system with the working frequency in the range of 50-60 Hz and the rated working voltage of 220V/380V. The device can provide a quick and safe standard shore power interface for the port-leaning ship, and ensure that the ship can be stably and efficiently connected to a shore power supply during berthing. In addition, the shore power box has diversified functions of cable distribution power supply, data acquisition, charging, settlement and the like, not only improves the intelligent level of port power supply, but also effectively reduces carbon emission and noise pollution during the port leaning period of the ship, and contributes important strength to building a green and environment-friendly port environment. At present, the shore power box is provided with an interlocking device when in use. The interlocking device is key equipment for ensuring safe and reliable connection between the shore power box and the ship power supply system, and can effectively prevent load starting caused by misoperation, thereby eliminating potential safety hazards of the shore power system. The most basic interlocking device is in the form of a door lock, and can be conveniently opened by a key. Likewise, such interlocks are also used on the case and seal door of shore power boxes. However, such interlocks rely primarily on a key to operate, which, once inadvertently lost, can result in the interlock failing to open. Further, when it is necessary to open the shore power hookup, great inconvenience and difficulty are encountered.
