The invention relates to the technical field of electric energy measuring, in particular to a current transformer convenient to splice. The current transformer comprises a current transformer body, aclamping base body and a clamping mechanism, the clamping base body is rotationally arranged on the current transformer body, the clamping mechanism comprises a first clamping part, a second clampingpart and elastic reset components, the first clamping part is hinged to the clamping base body, the second clamping part is hinged to the clamping base body, a first clamping structure is arranged onthe first clamping part, the first clamping structure is located on the side, close to the second clamping part, of the first clamping part, a second clamping structure is arranged on the second clamping part, the second clamping structure is located on the side, close to the first clamping part, of the second clamping part, and the elastic reset components are arranged on the first clamping partand the second clamping part respectively and drive the first clamping part and the second clamping part to swing so that the first clamping structure and the second clamping structure can get close to each other. By means of the current transformer, the installing and detaching convenience of the current transformer can be improved.
Description
technical field [0001] The invention relates to the technical field of electric energy measurement, in particular to a current transformer which is convenient for splicing. Background technique [0002] With the development of power system, new requirements are put forward for power system metrology and measurement. Current transformers are important equipment for energy metering and measurement in power systems. [0003] A current transformer is an instrument that converts a large current on the primary side into a small current on the secondary side for measurement based on the principle of electromagnetic induction. 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. [0004] The traditional current transformer is fixed in the equipment of the line to be measured by fasteners, which is inconvenient to install and disassemble; especially when measuring multi...
