Title:
METHOD FOR MEASURING SYNCHRONICITY OF CONTACTS OF TWO-POWER SUPPLY TRANSFER SWITCH AND APPARATUS FOR SAME
Document Type and Number:
WIPO Patent Application WO/2021/082906
Kind Code:
A1
Abstract:
A method for measuring the synchronicity of contacts of a two-power supply transfer switch and an apparatus for same, relating to the field of electrical device measurement. The method comprises: corresponding corresponding contact sets and states of switches with keys and states of a keyboard respectively, acquiring a device frequency value of a computer, acquiring and storing a first numerical value set of a counter when a first key set is in a closed state, acquiring and storing a second numerical value set of the counter when a second key set is in the closed state, and respectively calculating the differences between each numerical value in the first numerical value set and one numerical value therein, and respectively calculating the differences between each numerical value in the second numerical value set and one numerical value therein. The frequencies of currently common computers can cause the measured precision to reach the microsecond scale, and the synchronicity precision measured by the present contact synchronicity measurement method and apparatus is dependent on the device frequency of the computer. The synchronicity of connecting and disconnecting in all contacts of a transfer switch can be collected and measured at one time.
