The present invention relates to an optimal reclosing method of a circuit breaker for improving system transient stability and reducing turbine generator transient torque. The method comprises: step (a) of obtaining a voltage phase angle of both ends of a line after malfunction is removed from a permanent malfunction condition and a preceding circuit breaker is inputted into a reclosing path; step (b) of calculating a reclosing time when the obtained voltage phase angle becomes minimum and generating a reclosing signal at a calculated optimal reclosing time; step (c) of calculating a natural frequency of a turbine generator shaft system, which is a protection target, and calculating a malfunction removing time; step (d) of setting an optimal reclosing time which operates a circuit breaker by avoiding an unfriendly reclosing time from the calculated reclosing time and the calculated malfunction removing time and generating an optimal reclosing signal; and step (e) of enabling a following ...

SEAT ARMREST CAPABLE OF WITHDRAWING AUXILIARY HOLDER

Номер: KR1020160093955A
Автор: PARK, JI KYUNG
Принадлежит:

The present invention relates to a seat armrest with an auxiliary holder capable of being used by being withdrawn from a main holder, to add an auxiliary holder to hold a food container such as popcorn and so on by using a beverage cup holder installed in the end of an existing seat armrest of a movie theater, so as to provide audiences with convenience by eliminating the inconvenience of having to hold a food container when watching a movie. According to the present invention, being added to an existing beverage cup holder, a sliding type auxiliary holder is withdrawn and used as necessary like a drawer, and fixes a food container to be held by adjusting the withdrawal distance according to the size of the food container. Moreover, since the auxiliary holder is installed in a lower surface part of a main holder to be rotated by rotating a plate fixed on a rotating shaft, a location holding the auxiliary holder is adjusted by turning the food container towards a front side of a user and ...
