Description

Technical Field

[0001] The utility model relates to the technical field of current transformer detection, in particular to a detection platform for current transformers. Background Art

[0002] The principle of current transformer is based on the principle of electromagnetic induction. The current transformer is composed of a closed iron core and a winding. Its primary winding has very few turns and is connected in series in the circuit of the current to be measured. Therefore, it often has the entire current of the circuit flowing through it. The secondary winding has more turns and is connected in series in the measuring instrument and the protection circuit. When the current transformer is working, its secondary circuit is always closed. Therefore, the impedance of the series coil of the measuring instrument and the protection circuit is very small, and the working state of the current transformer is close to a short circuit. The current transformer converts the large current on the primary side into a small current on the secondary side for use, and the secondary side cannot be open.

[0003] When testing a current transformer, it is usually necessary to fix the current transformer in position in advance to prevent the current transformer from moving during subsequent testing. However, existing testing platforms cannot fix current transformers of various heights.

[0004] For example, a Chinese patent application numbered CN215180364U discloses a current transformer test bench, comprising a frame, a working platform being provided at the upper end of the frame, a layer of insulating pad being installed on the working platform, a mounting hole being provided on the insulating pad, three detachable copper bars being installed side by side in the mounting holes, the copper bars being arranged in a vertical direction, a connecting hole being provided at the bottom end of each copper bar, and a detachable short-circuit bar being installed at the bottom ends of the three copper bars through the connecting hole.

[0005] The current transformer test bench in the above patent also has a structure that is not convenient for testing current transformers of different heights, resulting in unstable fixation of the current transformer, which easily affects the safety protection of the current transformer. Therefore, we need to propose a current transformer test bench. Utility Model Content
