Power grid device condition monitoring method

Abstract

The invention provides a power grid device condition monitoring method. The method comprises the steps that a a capacitor closing limit A1 and a switch closing limit B1 are set; b a capacitor closingwarning value A2 and a switch closing warning value B2 are set; c the number of times A3 of effective closing of a capacitor and the number of times B3 of effective closing of a switch are counted; dif A3 is less than or equal to A2, a capacitor circuit breaker is normal; if A2 is less than A3 which is less than or equal to A1, the capacitor circuit breaker is in an early warning state; if A3 isgreater than A1, the capacitor circuit breaker is in an over-limit state; e if B3 is less than or equal to B2, an outlet switch circuit breaker is normal; if B2 is less than B3 which is less than or equal to B1, an outlet switch circuit breaker is in an early warning state; if B3 is greater than B1, the outlet switch circuit breaker is in an over-limit state; and f when the capacitor circuit breaker is in the early warning state or when the outlet switch circuit breaker is in the early warning state, a power grid device is to be repaired, and the staff is reminded to arrange maintenance for the power grid device, and the power supply of a power grid can be more stable and reliable.

Description

technical field [0001] The invention relates to a method for monitoring the state of power grid equipment. Background technique [0002] As users have higher and higher requirements for power supply reliability, electric power companies have also put forward higher requirements for safety, economy, stability, operation and provision of high-quality power supply services. At present, power grids have increased investment in urban and rural power grid construction. The hardware conditions have been improved to improve the equipment level. However, due to the limit of the number of operations of the capacitor circuit breaker and the outlet switch circuit breaker, it is easy to be scrapped after a period of use, resulting in unstable use of the power grid equipment. Contents of the invention [0003] The purpose of the present invention is to provide a method for monitoring the status of grid equipment, which monitors the status of the grid equipment in real time, so that the ...
