Real-time online monitoring method for protection pressing plate

Abstract

The invention relates to a real-time online monitoring method for a protection pressing plate. The method comprises the following steps that: S1: the ID (Identity) number of a monitoring terminal andthe protection pressing plate are associatively matched, the mentoring terminal is installed just below the connecting sheet of the pressing plate, and the monitoring terminal collects whether the protection pressing plate is positioned on a proper position or not through a non-contact method; and S2: a monitoring result is wirelessly transmitted to a collector by the monitoring terminal, the collector transmits a collected monitoring terminal signal to a regulation and control master station through the network, and the regulation and control master station analyzes signals transmitted by allcollectors, and provides the signals for a human-computer interaction interface. By use of the method, heavy losses caused since a real-time monitoring alarm can not be given after a manual operationhas errors can be avoided, the management efficiency of pressing plate state information is effectively improved, and the method is suitable for the unattended requirements of a transformer substation. Working efficiency is greatly improved, and the requirement of an operation and maintenance "2+N" working mode can be met.

Description

technical field [0001] The invention relates to a real-time on-line monitoring method for a protective pressing plate. Background technique [0002] With the advancement of the "2+N" work mode of substation operation and maintenance and the progress of the reform of integrated regulation, relying on the improvement of substation automation technology, the substation has fully realized unattended operation and remote monitoring and operation of equipment. However, the substation protection pressure plate management still adopts the manual mode, and the operation and maintenance personnel go to the substation site to perform status inspection and check and commissioning and withdrawal operations. Because the distance between substations is long, the work efficiency is low, and the cycle is long, the pressure plate status check is completely dependent on operation. The regulations and the sense of responsibility of the staff, there is no special online monitoring means, and the...

Problems solved by technology

However, the substation protection pressure plate management still adopts the manual mode, and the operation and maintenance personnel go to the substation site to perform status inspection and check and commissioning and withdrawal operations. Because the distance between substations is long, the work efficiency is low, and the cycle is long, the pressure plate status check is completely dependent on operation. The regulations and the sense of responsibility of the staff, no special online monitoring means, and the inspection quality is low

At the same time, due to the highly dense layout of the protection platen, highly integrated and complex functions, manual inspections are prone to omissions and operational errors
