Dc leakage current sensor
Dc leakage current sensor is a kind of power monitoring device, mainly used to detect leakage current in DC circuit. Here I will elaborate for you:
First, what is DC leakage current?
Dc leakage current refers to the abnormal current flow in the DC circuit due to reasons such as insulation failure. Under normal circumstances, there should be no leakage current in the DC circuit, but if the insulation material is aging or damaged, there will be abnormal loss of current in the circuit.
Two, DC leakage current sensor working principle
The DC leakage current sensor detects the leakage current in the DC circuit to monitor and protect the circuit. Its working principle is that the leakage current in the circuit is introduced into the transformer through the sensor induction device, through the transformer is converted into a voltage signal proportional to the leakage current, and then through the circuit processing and amplification, and finally output to the electronic equipment for monitoring and analysis.
Three, DC leakage current sensor application field
Dc leakage current sensor is widely used in leakage current monitoring and protection of power system, such as substation, motor, battery pack, charging pile and other equipment. By monitoring and alarming the abnormal situation of leakage current in time, it can effectively prevent and avoid the occurrence of circuit failure and safety accident.
Four, the characteristics of DC leakage current sensor
Dc leakage current sensor has the characteristics of fast response, high precision, good reliability, easy installation and maintenance. Its ability to accurately monitor leakage current can ensure the normal operation of circuits, avoid circuit failures, and ensure the safety of personnel and equipment.
5. Application cases of DC leakage current sensor
For example, DC leakage current sensors are usually installed in electric vehicle charging piles to ensure the safety and reliability of charging piles. When there is leakage current in the charging pile, the sensor will immediately send an alarm signal to prevent the leakage current from causing injury and property loss to the electric vehicle and the user.
Vi. Summary
Dc leakage current sensor is an important power monitoring device. By accurately detecting and alarming the leakage current in the circuit, it can effectively guarantee the normal operation of the circuit and the safety of personnel and equipment. With the development of power system and the improvement of intelligence level, the application of DC leakage current sensor will be more and more extensive, and will be more intelligent and convenient.
