High-low voltage switchgear capable of remote control

Abstract

The present invention discloses a high-low voltage switchgear capable of remote control. The switchgear comprises: a switchgear body; an upper computer system monitoring layer comprising a monitoring server and a monitoring host, wherein the monitoring host is configured to inquire the field measurement data in the monitoring server, the operation data of protection devices and the operation data of control devices; a field protection measurement and control unit layer comprising a plurality of measurement devices, protection devices and control devices, wherein the measurement devices are configured to generate field measurement data; a mobile terminal configured to check the field measurement data in the monitoring sever, the operation data of the protection devices and the operation data of the control devices; and a cloud server, wherein the mobile terminal uploads data to the cloud sever, and the cloud server automatically deletes the data uploaded by the mobile terminal when the mobile terminal is disconnected from the monitoring host. The high-low voltage switchgear capable of remote control designs the upper computer system monitoring layer and the communication management layer so as to realize the remote automatic monitoring of the yield protection measurement and control unit layer in the switchgear body.

Description

technical field [0001] The invention relates to a remote control high and low voltage switchgear. Background technique [0002] At present, the distributed control system (DCS) of power plants led by thermal automation has been widely used, but most of them focus on steam turbines and boilers, and less consideration is given to the electrical system. The control and automation level between the boiler and the electrical system uncoordinated. The electrical automation system of traditional power plants uses physical hard wiring and a large number of hardware devices such as transmitters and I / O cards to collect electrical information and control electrical equipment. Information such as measurement, protection action, setting, and accident recall of the electrical system cannot be accessed on the DCS. Fully responding, it is impossible to realize the functions of electrical analysis and management on DCS. [0003] In the power system of the power plant, each switchgear need...
