Embodiment Construction

[0034] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0035] Embodiments of the Invention References Figure 1-4 shown.

[0036] This application relates to an intelligent switching station, which includes main work equipment and monitoring equipment. The main work equipment includes a box body, an isolating switch and a circuit breaker. The box body is a fully enclosed inflatable cabinet filled with SF 6 The gas is used as the insulating medium, and the isolating switch and the circuit breaker are arranged in the box, and the connection between the isolating switch, the circuit breaker and the box is insulated by pouring epoxy resin products.

[0037] SF 6Gas has high insulation performance, about three times that of air. Epoxy resin has good adhesion, heat resistance, high mechanical strength, and excellent electrical insulation performance. using SF 6 Gas and epoxy resin composite insulation can eff...

Abstract

The invention relates to an intelligent switching station which comprises working main equipment and monitoring equipment, wherein the working main equipment comprises a box body, a disconnecting switch and a circuit breaker; the circuit breaker is a permanent-magnet vacuum circuit breaker, and comprises a vacuum arc extinguishing chamber, an energy storage mechanism, an interlocking mechanism, a switching mechanism, a buffer and a control device; the vacuum arc extinguishing chamber is integrally T-shaped, and comprises a flange plate, a ceramic housing, a metal housing, a bellows, a movable conducting rod, a static conducting rod and a spring buffer; the monitoring equipment comprises a bottom layer part and a station control part; the bottom layer part is used for obtaining a working parameter of the working main equipment and feeding back the working parameter to the station control part in real time; and the station control part is used for analyzing, processing and using uploaded data and controlling operation of the working main equipment.

Description

technical field [0001] The application relates to a switching station, especially an intelligent switching station. Background technique [0002] With the rapid development of our country's economy, especially in areas with rapid economic development, the power load is also increasing rapidly, and the demand for switching station facilities continues to increase. It is inevitable and the only choice to adopt an intelligent switching station system . The so-called intelligent opening and closing station system refers to the application of mature electronics, communication, network, graphics and other technologies and combining with the opening and closing station equipment to monitor, control, protect and manage the opening and closing stations in operation advanced technology. Practice has proved that once intelligent control is applied to the switching station, it can increase the safe operation level of the switching station system, improve the quality of power supply, s...
