I-shaped current transformer

Abstract

The invention discloses an I-shaped current transformer. The I-shaped current transformer comprises a shell, a magnetic arranged in the shell, and a coil wound on the magnetic core; the magnetic core is an I-shaped structure, and the coil is wound on a middle connecting rod of the magnetic core; the product is simple in design, and convenient for installing and power-taking, so that a plurality of device applications needing field power-taking can be realized, the requirements on different power transmission diameter sizes or busbar widths are satisfied, the security is reliable, the I-shaped current transformer can deviate from other cable busbar when being installed and cannot influence alternative insulation pitches of the voltage, the running of a power system is guaranteed; through the adoption of a permalloy magnetic core, the weight of the transformer is lightened, and the transformer is more portable.

Description

technical field [0001] The invention relates to the field of transformers, in particular to an I-type current transformer. Background technique [0002] In the power system, current transformers are widely used to obtain power online and supply power to power equipment. However, most of the current transformer power collection devices currently used are ring-shaped. When the current transformer needs to be placed on the cable transmission line or busbar, It is necessary to disconnect the transmission line or the busbar and then insert the current transformer. This design brings great inconvenience to on-site installation, and sometimes it cannot even be applied on-site. Even if the open-loop current transformer can take power, it is not convenient to install the open-loop cable and then close the loop on site. At the same time, these loop-shaped current transformers are all heavy iron cores, which are large in size and will affect the transmission line. The safe spacing, an...

[0002] In the power system, current transformers are widely used to obtain power online and supply power to power equipment. However, most of the current transformer power collection devices currently used are ring-shaped. When the current transformer needs to be placed on the cable transmission line or busbar, It is necessary to disconnect the transmission line or busbar and put it into the current transformer. This design brings great inconvenience to on-site installation, and sometimes it cannot even be applied on-site

Even if the open-loop current transformer can take power, it is not convenient to install the open-loop cable and then close the loop on site. At the same time, these loop-shaped current transformers are all heavy iron cores, which are large in size and will affect the transmission line. The safe spacing, and the inner diameter of the ring current transformer cannot meet the thickness and width of all field cables and busbars
