Description

Technical Field

[0001] The utility model relates to the technical field of feeder cabinets, in particular to a low-voltage feeder cabinet with a suspended isolation type terminal block. Background Art

[0002] A feeder cabinet, also known as a distribution cabinet, is a crucial piece of equipment in a power system. Its primary function is to distribute and provide power to external devices. It houses key components such as the closing busbar, control busbar, circuit breakers, current transformers, and intelligent power measurement and control instruments. These components are responsible for disconnecting and protecting the busbar and distributing power to various terminal devices. Feeder cabinets are widely used in enterprises, institutions, industrial and mining enterprises, shopping malls, and entertainment venues, particularly in these high-capacity locations, where they play a particularly significant role.

[0003] The terminal blocks in the low-voltage feeder cabinets of the prior art have some disadvantages. First, most of them are not installed in a suspended isolated manner, and most of the terminal blocks are installed in a fixed form. When the terminal blocks need to work independently, the distance between them cannot be adjusted, which easily causes multiple terminal blocks to affect each other. Second, it is not easy to add or remove terminal blocks, and the practicality is poor. Utility Model Content
