Abstract

The invention relates to a method and system for detecting the state of switch equipment. The method comprises the following steps: obtaining the current operation start time of the switch equipment, and calculating a current operation time parameter of the switch equipment according to the current operation start time, wherein the current operation time parameter is a parameter for representing the current operation time duration of the switch equipment; calculating the state parameter of the switch equipment according to the current operation time parameter and a preset state detection formula; and detecting the state of the switch equipment according to the state parameter and a preset state reference value. According to the invention, the method and system are simple in state detection process, and are high in detection efficiency. Moreover, the corresponding state detection result is higher in accuracy.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a method and system for detecting the state of a switchgear. Background technique [0002] With the advancement of smart grid construction, the dispatch system is the core part of the smart grid, and there are higher requirements for the intelligence of the dispatch system and the comprehensiveness of its functions. As an important part of the power grid, switchgear such as circuit breakers has important reference value for the safe and stable operation of the power grid through real-time monitoring of its status and status judgment based on the monitoring results. [0003] The existing switch on-line monitoring device generally adopts the method of installing sensors on the switch equipment to obtain the status data of the switch. This method has the following disadvantages: the installation of on-line monitoring sensors is large, one sensor corresponds to one device, an...
