Electric power intelligent switch device

Abstract

The invention discloses an electric power intelligent switch device. The switch device comprises an intelligent terminal, a merging unit and a state monitoring IED. The intelligent terminal is connected with a switch body via a cable and connected with secondary devices like a protection device and a measurement and control device via fibers. The secondary devices are used for measuring and controlling the switch device. The merging unit is used for combining current and / or voltage data of a secondary converter. The state monitoring IED is installed on or near the switch device body and is used for receiving data sent by a sensor of a to-be-monitored switch device body. Thus, acquisition, processing, analysis and conversion of data can be achieved; intelligent control for operation can be carried out according to actual operation conditions; and state maintenance can be performed according results of state detection and fault diagnosis.

Description

technical field [0001] The invention relates to the technical field of electric power equipment, in particular to an electric power intelligent switching device. Background technique [0002] Judging from the situation of the smart substation that has been built, the research and development and production of smart switchgear are still in the stage of "power functional components + smart components", that is, the way of "switchgear body + sensors and actuators + smart components", integrated The degree is still low; the intelligent unit has not yet integrated all the control units, measurement units, power protection, and measurement units. From the current situation, the power protection, measurement units, and measurement units of the switchgear have not yet been decentralized. Relay room: From the current situation, most of the current condition monitoring IED products cannot analyze the current operating status of the monitored equipment based on sensor information, or c...

[0002] Judging from the situation of the smart substation that has been built, the research and development and production of smart switchgear are still in the stage of "power functional components + smart components", that is, the way of "switchgear body + sensors and actuators + smart components", integrated The degree is still low; the intelligent unit has not yet integrated all the control units, measurement units, power protection, and measurement units. From the current situation, the power protection, measurement units, and measurement units of the switchgear have not yet been decentralized. In the relay room; Judging from the current situation, most of the current status monitoring IED products cannot analyze the current operating status of the monitored equipment based on sensor information, or can only analyze part of the information parameters.
