Current transformer support frame

Abstract

The invention discloses a current transformer supporting frame, and the frame comprises a transformer; a high-voltage binding post and a low-voltage binding post are arranged at the top of the transformer, and a mutual inductance mechanism is installed on the right side of the top of the transformer. The mutual inductance mechanism comprises a support, a supporting rod, a transformer box and a transformer, and the left side of the support is clamped to a protrusion on the right side of the top of the transformer; bolts are installed at the upper end and the lower end of the left side of the support and are in threaded connection with the left side of the support, an installation base is fixedly connected to the top of the support, and a top transformer box of the installation base is movably installed at the top of the installation base. The three mutual inductors are installed on a fan-shaped sliding rail II, the three mutual inductors form a fan shape, and therefore wires can easilypenetrate through and be easily wired, the mutual inductor box is installed on the installation base, the installation base is fixedly connected to the support, the support is tightly connected to theprotrusion on the right side of the transformer through bolts, and the mutual inductor box is not prone to loosening.

Description

technical field [0001] The invention relates to the technical field of bench-type transformer electric energy measurement, in particular to a current transformer support frame. Background technique [0002] A power transformer is a static electrical device that is used to change an AC voltage (current) of a certain value into another voltage (current) with the same frequency or several different values. The principle of magnetic induction converts a large current on the primary side into a small current on the secondary side for measurement. A current transformer consists of a closed core and windings. Its primary side winding has few turns and is connected in series with the current line to be measured. [0003] At present, the current transformer installed on the transformer adopts the "high-type" layout of the transformer box, and the box is directly hooked on the low-voltage outlet line without fixing. Or fix it with a cross arm or I-beam directly above the transforme...

Problems solved by technology

[0003] At present, the current transformer installed in the transformer adopts the "high-type" layout of the transformer box, and the box is directly hooked on the low-voltage outlet line without fixing

Or fix it with a cross arm or I-beam directly above the transformer, which is high from the ground and close to the high-voltage line, which is not conducive to maintenance and daily observation

There is also an installation method in which the transformer is directly exposed, which has a greater potential safety hazard
