Capacitor expansion monitoring system and monitoring method

Abstract

The invention discloses a capacitor expansion monitoring system and method, and the system comprises a plurality of pressure sensors, and each capacitor unit is provided with at least one pressure sensor; at least two data concentrators, wherein each pressure sensor is correspondingly connected with one data concentrator; the data concentrator is used for detecting the environment temperature of the environment and collecting surface pressure data of the pressure sensor connected with the data concentrator; the data concentrator is also used for sending the event data to the server through the gateway; the server is used for sending a data packet of the data concentrator serving as an event publisher to the data concentrator serving as an event subscriber through the gateway according to the collaborative awareness relationship among the data concentrators; a data concentrator as an event subscriber determines an expansion risk level of a self-monitored capacitor unit from data in the data packet. The capacitor expansion monitoring efficiency is improved, and stable and safe operation of a power grid system is ensured.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of capacitor expansion detection, in particular to a capacitor expansion monitoring system and monitoring method. Background technique [0002] With the development of science and technology, the inductive load in the power grid is increasing day by day. Therefore, in order to reduce the reactive power loss of the inductive load to the power supply, a large number of parallel capacitor devices with corresponding indicators are used in the power grid to perform reactive power compensation. [0003] The parallel capacitor device is composed of multiple capacitor units. When a capacitor unit is damaged or even damaged due to a series of reasons such as ambient temperature and load overload, the capacitor bulges and expands and cannot be found and solved in time. This is a very dangerous situation for the power grid system. The hidden dangers are very likely to lead to the instability of p...
