Abstract

A communication module of a controller is used to output commands relating to the operation and the monitoring of auxiliary equipment to be operated. A communication module of switch device is used to generate information relating to the protection and the interlocking of the auxiliary equipment to be operated. The communication module of the controller and the communication module of the switch device are mutually connected through serial transmission cable conductors. All devices in the switch device are mutually connected through the serial transmission cable conductors. The protection operation and the interlocking operation of the auxiliary equipment to be operated can be implemented through controlling a CPU in the switch device which is connected with a power circuit when the auxiliary equipment to be protected receives a starting command. A device of small scale can be obtained, and the connection cables can be reduced.

Description

technical field [0001] The present invention relates to a switchboard switchgear and a monitoring system with a switchboard switchgear, in particular to a switchboard switchgear and a monitoring system with a switchboard switchgear suitable for controlling the operation and monitoring of various special devices, these special devices It is used in hydropower plants, thermal power plants and nuclear power plants. Background technique [0002] In a nuclear power plant, a system for operating various specialized devices is constructed based on commands output from the main control panel. For example, there is an article titled "Instrumentation Control and Automation for Thermal Power Plants" that appeared in "Thermal and Nuclear Power Generation" in July 1993. [0003] In this paper, a main control panel and a unit main computer are arranged in the central control room, and an auxiliary equipment program controller is connected with the unit main computer through a network. I...
