Abstract

The invention discloses a monitoring system and method of a ring main unit. The monitoring system includes a transmission cable which is connected with the ring main unit and is used for transmitting current, a current detection device which is connected with the transmission cable and is used for detecting the current value of the current and generating fault information indicating a fault occurring on the transmission cable according to the current value, a temperature sensor which is arranged on the transmission cable and is connected with the current detection device, and is used for detecting the temperature of the transmission cable, and a controller which is connected with the current detection device and the temperature sensor respectively and is used for generating monitoring results according to the fault information and the temperature of the transmission cable. With the monitoring system and method of the invention adopted, technical problems of low signal acquisition precision and inaccurate monitoring of a monitoring system of a ring main unit in the prior art can be solved.

Description

technical field [0001] The invention relates to the field of electric power, in particular to a monitoring system and method for a ring network cabinet. Background technique [0002] Ring main unit has a wide range of applications in the field of power supply, and has played a very important role in the construction of urban power supply network. At present, there are no mature products for the comprehensive intelligent monitoring of ring network cabinets at home and abroad. The fault indicator used, the sensor cannot measure the current, and the fault judgment accuracy is low, the error is large, and the temperature indicator only detects the ambient temperature inside the cabinet. In the related art, the monitoring system of the ring network cabinet has low signal acquisition accuracy and inaccurate monitoring. [0003] For the above problems, no effective solution has been proposed yet. Contents of the invention [0004] Embodiments of the present invention provide a ...
