Abstract

The invention relates to the technical field of power automation, especially to an intelligent detection system and method for a current temperature signal. The intelligent detection system is composed of a current temperature sensor, a transmission fiber, and a fault indication host. The current temperature sensor consists of a coil sampling loop, a processing control unit, a current memory unit, a comparator, an adding device, and a photovoltaic conversion. A current temperature signal is transmitted by one fiber. When a digital signal is transmitted by a fiber, the interference from any clutter like electromagnetism or radio frequency is avoided and the fault detection accuracy is improved. Because of fiber application, the damage on the fault indication host and the threat on the personal safety by one-time link leakage can be eliminated. With the current memory unit, the comparator, and the adding device, the operating line is monitored by using an adaptive algorithm, so that a problem of wrong reporting faults for closing, a surge current, an instantaneous heavy current according to an original calculation method can be solved. The system power consumption is reduced.

Description

technical field

[0001] The invention relates to the technical field of electric power automation, in particular to an intelligent detection system and method for current and temperature signals. Background technique

[0002] At present, when the current is detected during cable transmission, the commonly used products include cable type current temperature sensor and segment code LCD display fault indicator and other products. In the existing cable-type current temperature detection and fault indication device, the signal captured by the sensor is transmitted to the host through the cable, and the current and temperature information of the cable after the host receives the signal.

[0003] However, the conventional current and temperature signal detection device has the following defects: First, the conventional cable-type product sensor needs an external power supply to work normally due to the large power consumption of the cable transmission, and the cable transmission pr...
