Ring main unit state monitoring method

Abstract

The invention provides a ring main unit state monitoring method which comprises the following steps of configuring electronic tags for the components in ring main units, and transmitting and storing the state data information and the position information of the components of the ring main units by using the electronic tags; calculating the position coordinates of the electronic tags based on an APIT algorithm, and summarizing and dividing the number of the electronic tags and the information of the ring main units to which the electronic tags belong; placing the electronic tags belonging to the same ring main unit in the same candidate space, and sequentially arranging the electronic tags with different coordinates in the candidate space according to the recorded component information; and setting a periodic polling mechanism, carrying out self-adaptive monitoring on the state data of the ring main units on the electronic tags regularly, and sending a monitoring result to the background of a power grid monitoring center for management and control. The invention provides a high-efficiency and more reliable ring main unit state monitoring means for the ring main units which are of totally-closed structures and cannot be inspected manually so as to guarantee the electricity demands and the safety.

Description

technical field [0001] The invention relates to the technical field of ring network cabinet monitoring, in particular to a state monitoring method of a ring network cabinet. Background technique [0002] In recent years, the construction of smart grid has been highly valued and has achieved considerable development. The intelligence and informatization of power transmission and transformation systems have developed to a certain level. The ring main unit (or distribution transformer) is located at the end of the distribution network and is used for It is self-evident that the 10kV high-voltage power delivered by the substation is converted into 0.4kV lighting power and power power for residents, so the importance of ensuring its effective operation is self-evident. [0003] However, at present, the intelligent monitoring construction of ring network cabinets is obviously lagging behind. The main reason is that the number of ring network cabinets is large, the installation loc...
