The invention discloses a current transformer auxiliary installation equipment used on a metering device, which belongs to the technical field of electric power operation and maintenance equipment; it includes a rectangular main box with a hollow interior and an opening structure on the front side; There are more than three sets of guide through holes on the side wall, and guide rails are installed on the inner bottom of the main box; the auxiliary positioning block is movably installed on the guide rail; the current transformer is detachably installed on the auxiliary positioning block; The wire row passes through the inner ring of the iron core on the current transformer and is set opposite to the guide through hole, and the primary wire row and the guide through hole are connected by a connecting tube; the invention effectively solves the current problem that cannot be realized when installing the current transformer Its convenient and quick installation in the mechanism box affects the work efficiency.
Description
technical field [0001] The invention relates to the technical field of electric power operation and maintenance equipment, in particular to an auxiliary installation equipment for current transformers on a metering device. Background technique [0002] In the power grid system, the current transformer is often used as the test piece of the meter box for electricity trade settlement. Most of the conventional domestic electricity and industrial electricity use the three-phase four-wire wiring structure as the measurement standard; although the working principle of the current transformer It is relatively simple, but the current transformers often used in China also have differences in structure and size due to different manufacturers and local implementation standards; on the other hand, current transformers cannot be directly installed in the external environment as power equipment. The structure of the conventional mechanism box is generally set by directly passing the load ...
