Abstract

The invention discloses a current acquisition sensor, and belongs to the technical field of current sensors, the current acquisition sensor comprises a shell, a fixed coil, a movable coil, a cable installation position, a power taking wire pressing plate and a locking screw, the locking screw is installed in the middle of the lower portion of the shell, a torque damper is arranged on the locking screw, the fixed coil is arranged on the upper portion of the interior of the shell, and the movable coil is arranged on the lower portion of the shell. Springs are arranged on the left side and the right side below the shell. A movable electricity-taking locking piece is arranged on the lower portion of the interior of the shell, a movable coil is installed on the movable electricity-taking locking piece, and a cable guide groove is formed between the movable coil and the fixed coil. According to the invention, the current acquisition device and the voltage acquisition device are designed in an integrated structure, so that the voltage and current of a line can be detected in real time with high precision, energy taking is realized, live-line mounting and dismounting can be realized, the current acquisition device is in tight and reliable contact with a lead, and the current acquisition device and the voltage acquisition device are convenient to use. And the sampling signal accuracy is higher.

Description

Technical field [0001] The present invention belongs to the technical field of current sensor, and is specifically a current acquisition sensor. Background technique [0002] As people have more and more actual demand for power, there is more and more power devices to integrate new technologies. In order to automatically detect and display current, there is automatic protection function when hazardous, overvoltage, etc. Advanced intelligent control, with sensor detection, sensing sampling, sensor-protected power supply technology, and detecting current or voltage sensors are born and have been favored by the majority of power designers from my country. Current acquisition sensor is a current detecting device that can feel information that is measured, and can detect information, according to certain regular transformations into electrical signals or other required forms of information required for a certain standard, Meet the requirements of information transmission, processing, ...
