Pre-control system for dangerous point alarming during whole operation process of transformer substation

Abstract

The invention discloses a pre-control system for dangerous point alarming during a whole operation process of a transformer substation. The system comprises an anti-error host, a commutation adapter, a computer key and a coding lock; and five-prevention software is installed on the anti-error host. Besides, structural features of the system are as follows: a secondary pressure plate rule base is associated with the five-prevention software; and a lockset also includes a secondary pressure plate state detection lock that is used for detecting an operation of a secondary pressure plate. Advantages of the system provided in the invention are as follows: a pre-control system for dangerous point alarming during a whole operation process of a transformer substation is provided; the system has a current microcomputer five-prevention function and is capable of carrying out prompt and confirmation on operations during the operations of various equipment carrying dangerous point information, so that operational personnel are reminded to carry out operations cautiously and safety consciousness of the operational personnel can be strengthened.

Description

technical field [0001] The invention relates to a warning and pre-control system for substation operation, in particular to a warning and pre-control system for dangerous points in the whole process of substation operation. [0002] Background technique [0003] The operation of the power grid is becoming more and more complex, the safety production situation is severe, and the risks are increasing. At the same time, there are many types of equipment, inconsistent operation modes, and operators who neglect the requirements of safety monitoring for a while may encounter danger and cause accidents. In recent years, accidents have occurred from time to time due to the operator's carelessness and failure to take corresponding risk point analysis and preventive measures. [0004] The power system safety management department has always attached great importance to the safety of people and equipment. In order to effectively prevent personal and major equipment acc...

Problems solved by technology

Due to the various types and functions of anti-misoperation devices used in today's substations, although it has effectively prevented the occurrence of various vicious misoperation accidents, the new situation of continuous increase in the scale of the power grid and diverse and complex equipment poses new challenges to the safety of the power grid. , also exposed one by one the many deficiencies of the existing microcomputer error prevention system:

[0005] (1) The anti-malfunction system is only implanted with electrical logic once, and cannot inform of dangerous situations such as equipment defects during operation, changes in operation mode, and possible operational jams. Unable to prompt dangerous point information, p
