GIS (geographic information system) bus cylinder telescopic joint displacement monitoring device and monitoring method thereof

Abstract

The invention discloses a GIS bus cylinder telescopic joint displacement monitoring device and a GIS bus cylinder telescopic joint displacement monitoring method. The monitoring device comprises an ejector rod, a shell, a main control panel, a connecting block, a pressure spring and a positioning rod. The main control panel comprises a potentiometer, a control circuit, a temperature sensor, an acceleration sensor, a voltage reference source, a memory, a real-time clock, a positioning module, a wireless communication module, a power management circuit, a storage battery, a primary battery and a power interface. The potentiometer and a bus cylinder telescopic joint are linked, and the control circuit is used for measuring the stroke displacement amount of the potentiometer. According to the technical scheme of the invention, the parameters of the telescopic joint, including the displacement, the inclination, the vibration, the environment temperature and the like, can be automatically monitored, recorded and remotely transmitted.

Description

technical field [0001] The invention belongs to the technical field of smart grids, and in particular relates to a displacement monitoring device and a monitoring method for expansion joints of a GIS busbar barrel. Background technique [0002] Gas-insulated fully enclosed combined electrical equipment (GIS) has the advantages of compact structure, small footprint, high reliability, and strong safety. It is a high-voltage electrical distribution device with excellent comprehensive performance and has been widely used in power systems. . GIS equipment is interconnected by circuit breakers, disconnectors, transformers and busbars. The materials of these components are different, and the expansion coefficients are different. When the temperature changes, if each component cannot be freely elongated and shortened, the component will be damaged due to temperature stress. For this reason, the bus pipe of the GIS equipment should be equipped with expansion joints. The expansion j...
