Title:
SYSTEM FOR MONITORING OPERATION CHARACTERISTICS OF POWER SWITCH
Document Type and Number:
WIPO Patent Application WO/2023/106873
Kind Code:
A1
Abstract:
The present invention relates to a system for monitoring the operation characteristics of a power switch, and the system for monitoring the operation characteristics of a power switch, according to the present invention, comprises: an electrode sensor which is impregnated as a circular, angular, or pin-type structure in the inside of a conventional insulation material constituting a power switch, or which is separately provided in the form of a separable/detachable electrode sensor module on the outside so as to detect electrostatic voltage induced during position movement of a main contact of the power switch; and an integrated monitoring means which simultaneously operates and displays the switching time, three-phase operation time difference, stroke, and operating speed of each phase of the power switch on the basis of a voltage value input from the electrode sensor, and which outputs an alarm or a control signal for a lock if the operated output values deviate from the set range of operation characteristic limits.
