Abstract

The invention provides a state monitoring device, anti-misoperation device and monitoring and anti-misoperation method of a current terminal. The state monitoring device comprises a state monitoring module, a signal acquisition module and a signal processing module, wherein the state monitoring module comprises a plurality of current terminal state monitoring units, each current terminal state monitoring unit is used for monitoring input and exit states of each current terminal, the signal acquisition module is used for acquiring a monitoring result of the current terminal state monitoring unit and transmitting the monitoring result to the signal processing module, and the signal processing module is electrically connected with the signal acquisition module and is used for outputting a monitoring result according to a monitoring signal. By the state monitoring device, the problem of uncontrollable misoperation caused by dependence on management system and technical level, running experience and responsibility of a worker is solved, the operation of the current terminal is streamlined, personal and equipment accidents caused by manual misoperation can be reduced, and the safe running level of a power grid is improved.

Description

technical field [0001] The invention relates to the field of electric power, in particular to a current terminal state monitoring device, an error prevention device, and a monitoring and error prevention method. Background technique [0002] The primary large current of the power system is transformed into a small current through the current transformer, and then connected to the protection device through the current terminal. The switching of the current terminal is a common operation in the process of substation operation. Input and exit operation, switch the operating state of the current terminal, and connect the secondary current to or exit the protection. The operation of the current terminal needs to follow certain operating principles to prevent the open circuit of the secondary side of the current transformer from causing high voltage, which threatens the safety of people and equipment. At present, it mainly depends on the management system of the substation and th...
