Description

Vertical installation structure of current transformer of inflatable switch cabinet Technical Field The utility model relates to a current transformer installation structure, in particular to a current transformer vertical installation structure of an inflatable switch cabinet, which solves the problem of overrun of temperature rise of a feed line sleeve caused by installation of a current transformer at the sleeve, and has the advantages of simple structure, strong adaptability and stable installation. Background The current transformer of a common inflatable switch cabinet is usually installed by a sleeve, namely, the current transformer 3 is sleeved on a feeder sleeve 4 of the switch cabinet and is reliably fixed to a mounting plate through a horizontal direction. The installation mode effectively solves the requirement of loop current automatic monitoring under the condition that multiple feeder cables are connected in parallel, specifically, as shown in fig. 4, fig. 4 is a structural schematic diagram of a current transformer installation mode commonly used at present, in fig. 4, a current transformer 3 is sleeved on a feeder sleeve 4 of a switch cabinet and fixed to a mounting plate 5 through a horizontal direction, and the right end of the current transformer 3 is provided with multiple cables 6, so that the installation mode is unstable. In some special cases, such as when the switch cabinet monitors the temperature rise, the current transformer needs to be vertically installed instead of the sleeve type installation, so as to solve the problem of over-limit temperature rise of the feeder sleeve. This involves the problem of how the current transformer is mounted in a vertically reliable manner in the switchgear cabinet.
