Anti-interference waterproof current sensor

Abstract

The invention relates to the technical field of current sensors, in particular to an anti-interference waterproof current sensor which comprises a current sensor upper magnetic core, an upper magnetic core waterproof shell is installed outside the current sensor upper magnetic core, and a connecting threaded hole is formed in the right side of the upper magnetic core waterproof shell. A fixing bolt is installed in the connecting threaded hole, and a connecting rotating shaft is installed on the left side of the upper magnetic core waterproof shell. And the lower magnetic core waterproof shell is arranged below the upper magnetic core waterproof shell. The current sensor upper magnetic core and the current sensor lower magnetic core are wrapped by the upper magnetic core waterproof shell and the lower magnetic core waterproof shell, so that a waterproof effect on the current sensor is achieved, the current sensor is prevented from being damaged when encountering water, the service life of the current sensor is prolonged, and the service life of the current sensor is prolonged. And meanwhile, the anti-interference coatings on the inner walls of the upper magnetic core waterproof shell and the lower magnetic core waterproof shell play an anti-interference role, so that the current sensor is prevented from being interfered to influence the work of the current sensor.

Description

technical field [0001] The invention relates to the technical field of current sensors, in particular to an anti-interference waterproof current sensor. Background technique [0002] The current sensor is a detection device that can sense the information of the measured current, and can convert the information sensed by the detection into an electrical signal that meets certain standards or other required forms of information output according to certain rules, so as to meet the Information transmission, processing, storage, display, recording and control requirements, current sensors are also called magnetic sensors, which can be used in household appliances, smart grids, electric vehicles, wind power generation, etc. Many magnetic sensors are used in our lives. For example, computer hard drives, compass, household appliances and so on. [0003] The existing current sensor has poor waterproof performance, and working in an environment with a large water content will greatly...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide an anti-interference waterproof current sensor to solve the problem of the poor waterproof performance of the existing current sensor proposed in the above background technology, and the service life of the current sensor will be greatly reduced when working in an environment with a large water content , at the same time, the anti-interference performance of the current sensor is poor, and it is easy to be interfered by external interference sources and cause the problem that it cannot work normally
