Problems solved by technology

[0002] With the continuous development of electric power construction, GIS equipment is widely used in power plants because of its small footprint, high operational reliability, convenient maintenance, and long maintenance cycle. However, GIS knife switch equipment is mainly Encapsulating the dynamic and static contacts in the equipment filled with SF6 gas, the actual position of the knife switch contact cannot be seen intuitively, and the actual position of the knife switch contact can only be judged indirectly through the external operating mechanism and the position change of the connecting rod. The opening and closing indicator of the operation box can only indicate the operation of the operating mechanism. When the connecting rod falls off, the gap becomes larger, aging, corrosion, jamming and other problems cause the three phases to be inconsistent, the indicator of the knife switch operating mechanism and the background cannot be judged in time , Determining and discovering faults, the key work of judging the actual position of the knife switch falls on the inspection and operation experience of the operating personnel, which brings hidden dangers to the safe operation of the power plant
[0003] In recent years, the power system has reported that the three-phase linkage connecting rod of the GIS knife switch has fallen off, resulting in non-full-phase operation of the generator and the incomplete three-phase separation of the ground knife during power transmission. Combined with the current electrical switching operation, the status of the GIS knife switch is mainly Rely on the operator's electrical alignment, mechanical alignment, and background monitoring alignment, but the operation of the GIS knife switch is performed by the operating mechanism box, and the transmission rod of the operating mechanism box drives the three-connected rods to link the three-phase knife switch. Phase linkage, the operation box displays the switching state, which cannot effectively display the switching state of the three-phase knife switch. In order to avoid the three-phase connecting rod connection mechanism from slipping, bolts falling off, and the transmission gap increasing, resulting in inconsistent actions of the three-phase knife switch, Operators need to judge the position of the three-phase knife switch by marking the actual axis of each phase knife switch with "open and close" indications, marking lines, etc. Due to different standing positions, viewing angles, and experience, the judgment results are also different, and there is a possibility of misjudgment Sexuality, which brings hidden dangers to safe operation

Abstract

A GIS disconnecting link position monitoring system relates to the technical field of power equipment and comprises an indicating pointer, an indicating rod, an indicating dial, a detection mechanism and a processor. The indicating dial is sleeved on a GIS disconnecting link transmission rod and does not rotate along with the GIS disconnecting link transmission rod, the indicating pointer and the indicating rod are oppositely arranged front and back, are both mounted at the front end of the GIS disconnecting link transmission rod and rotate along with the GIS disconnecting link transmission rod, the indicating pointer and the indicating rod are positioned in front of the indicating dial, and detection mechanisms are mounted at corresponding switch positions on the indicating dial. The detection modules are used for detecting whether the indicating rod and the indicating pointer rotate to the switch position and transmitting detection information to the processor. The monitoring system is simple, convenient, flexible and practical, and can accurately judge and monitor the position of the GIS disconnecting link by utilizing dual judgment of the detection mechanism and the mechanical pointer, so that the judgment accuracy is improved, the pressure of operators is reduced, the safe operation of a unit is ensured, and electrical accidents are avoided.

Description

Technical field[0001]The present invention relates to the field of power devices, in particular, to a GIS knife gate position monitoring system.Background technique[0002]With the continuous development of electricity construction, the GIS equipment has been widely promoted in the power plant because of the advantages of small area, high operating reliability, convenient maintenance and maintenance, and maintenance cycle, the GIS combination switch equipment is widely promoted in the power plant, but the GIS knife gate equipment mainly Punch, the static contact is packaged in the equipment filled with SF6 gas. It cannot be intuitive to see the actual position of the tool gate contact, only through the outer operating mechanism, the link position change indirectly determine the actual position of the knife gate contact, due to the knife gate The integrated indicator of the operating box can only indicate the operation of the operating mechanism to in place. When the link is falling of...
