Transformer station computer monitoring maloperation preventing system

Abstract

The invention discloses a transformer station computer monitoring maloperation preventing system in the field of high-voltage electric power engineering technology. The transformer station computer monitoring maloperation preventing system comprises a computer monitoring maloperation preventing system, N parallelly connected measuring control devices and a plurality of sets of secondary equipment.The system is characterized in that N signal output ends of the computer monitoring maloperation preventing system are electrically connected with the input ends of the N parallelly connected measuring control devices; furthermore N signal input ends of the computer monitoring maloperation preventing system are electrically connected with the output ends of the N parallelly connected measuring control devices; each measuring control device is electrically connected with a button switch, a secondary pressure board and a changeover switch; the first output end of the measuring control device iselectrically connected with the input end of the button switch; the second output end of the measuring control device is electrically connected with the input end of the secondary pressure board; andthe third signal output end of the measuring control device is electrically connected with the input end of the changeover switch.

Description

technical field [0001] The invention relates to the technical field of high-voltage electric power engineering, in particular to a substation computer monitoring and anti-malfunction operating system. Background technique [0002] At present, the anti-mistake system of the power grid mainly includes the microcomputer anti-mistake system and the computer monitoring anti-mistake system. Among them, the microcomputer error prevention system is mainly composed of industrial computer, computer key, Chinese character display, analog components, communication adapter, transmission seat and power supply. Each operation is judged according to the rules: if the operation is correct, the device number will be displayed, and a sound signal of correct operation will be issued; if the operation is wrong, the device number of the wrong operation item will be displayed by flashing on the display, and a continuous alarm sound will be issued During operation, the operator inserts the compute...

Problems solved by technology

After the operation is finished, the computer key will automatically display the next operation content; if the wrong interval is detected, the computer key detects that the coded lock code does not match, and the lock cannot be unlocked. Due to the existence of the microcomputer anti-mistake computer key, there are many defects in the microcomputer anti-mistake, the system anti-interference ability is low, logic confusion is easy to occur, the program is easy to lose, the service life of the computer key battery is short, the system communication part is stable and easy to be interrupted, and the lock is easy to be lost. Corrosion, jamming, inflexibility of plugging and unplugging, etc. For this reason, we propose a substation computer monitoring and error prevention operating system to solve the above problems
