Abstract

The present invention provides a current sensor with simple and easy installation and removal operations. Therefore, the current sensor (1) of the present invention measures the current flowing through the covered electric wires (80a, 80b, 80c) from the outside. In particular, it includes: a sensor main body (10), which is equipped with a current sensor element, and is provided with incision-shaped insertion grooves (22a, 22b, 22c) that can respectively insert at least two of the electric wires; With a base (70) capable of holding the electric wires (80a, 80b, 80c) inserted into the insertion grooves (22a, 22b, 22c) on the bottom surface of the insertion grooves (22a, 22b, 22c).

Description

technical field [0001] The present invention relates to a current sensor and a power sensor for measuring electric power using the current sensor. Background technique [0002] At present, for example, as a current sensor, there is a "current transformer, which has a pair of iron cores with a split structure using a high-permeability material, coils applied to these two iron cores, and a through hole through which electric wires can pass through to accommodate them. The resin case is characterized in that the above-mentioned resin case has a waterproof function, and it is not saturated with a large current up to AC1000A of the primary current, and a current detection device with high measurement accuracy" (see Reference 1). [0003] Patent Document 1: (Japanese) Unexamined Patent Publication No. 2000-88889 [0004] However, since the above-mentioned current detection device has a shape surrounding electric wires, when installing the above-mentioned current detection device,...
