Remote monitoring system for automatic gas supplementing device of SF6 electrical equipment

Abstract

The invention discloses a remote monitoring system for an automatic gas supplementing device of SF6 electrical equipment. The remote monitoring system comprises a monitoring module, a control module, an abnormity alarming module, a data display module and a monitoring terminal, wherein the monitoring module is used for display the real-time condition of monitoring, and a display interface displays the condition in a form of a structure arrangement drawing of an actual gas supplementing device and further comprises current monitoring values of a pressure micro-water sensor and a current working mode of the gas supplementing device; the control module comprises a selection work mode, a set parameter threshold value and remote emergency stop in the fault situation of the gas supplementing device; the abnormity alarming module comprises monitoring values out of the range of a reference threshold value and starting and stopping of the gas supplementing device. The gas density, micro-water and other parameters as well as information including gas cylinder pressure, valve states and the like of the gas supplementing device are synchronized on a monitoring background and a mobile phone for display, the abnormity situation can be alarmed on the monitoring background and sent to a designated mobile phone in a form of short messages for reminding, and a worker does not need to check on scene regularly.

Description

technical field [0001] The invention belongs to the technical field of SF6 electrical equipment, and in particular relates to a remote monitoring system for an automatic gas supply device of SF6 electrical equipment. Background technique [0002] With the continuous promotion and use of SF6 circuit breakers, SF6 transformers, gas-insulated closed combination appliances (GIS or HGIS), and gas-insulated closed transmission lines (GIL), the scale of SF6 electrical equipment in power systems is increasing. The volume of a single air chamber is also gradually increasing. However, during the perennial operation, due to the deformation of the shell and the aging of the seals, SF6 electrical equipment often suffers from air leakage, and the subsequent frequent air replenishment also causes a sharp increase in the maintenance workload. With the development of pressure micro-water sensor technology and intelligent control equipment, many users and manufacturers have begun to develop ...

Problems solved by technology

However, most of the current automatic air supply devices only have local display and operation functions, and staff still need to go to the site to check the status of the equipment from time to time, and when the air supply device itself is abnormal, the staff cannot find and deal with it in the first place , has a greater safety risk, which is also an important factor restricting the promotion and use of automatic air supply devices
