본 발명은 다기능 전력수급용 복합계기의 시간대 분할설정 방법에 관한 것으로, 특히 전력량, 역률등을 평일, 토요일, 일요일(휴일)의 종류에 따라 계량의 시간대를 선택설정하도록 한 다기능 전력수급용 복합계기의 시간대 분할설정 방법에 관한 것이다.The present invention relates to a time zone division setting method of a multi-function power supply multi-function multi-function power supply, multi-function power supply multi-function multimeter for selecting the time zone of metering according to the type of power, power factor, etc. according to weekdays, Saturday, Sunday (holiday) It relates to a time zone division setting method.
일반적으로 적산전력량계라 하면 일정한 시간내에 소비되는 전력의 합계를 누산 표시하면서 요금을 산정하기 위하여 유효전력량등을 검침하도록 한 것임은 이미 잘 알려진 사실이다.In general, it is well known that an integrated electricity meter is used to read an effective amount of electricity in order to calculate a charge while accumulating and displaying the sum of power consumed within a certain time.
그리고 유효전력량을 측정하기 위하여 보통의 전력량계를 이용하면서 전일전력량과 최대수요전력의 정밀한 측정을 위해 정밀전력계를 사용하고, 다시 역률측정에 의한 무효전력량을 측정하기 위하여 타임스위치와 무효전력량계를 추가로 설치하여야 하였다.In addition, a normal power meter is used to measure the effective power amount, and a precision power meter is used to accurately measure the daily power and the maximum demand power, and a time switch and a reactive power meter are additionally installed to measure the reactive power amount by power factor measurement. It should be.
특히 업무용이나 산업용 수용가에서 평일이나 토요일 또는 일요일(휴일)에 따라 전력의 사용상태가 바뀌므로 계량을 할때 이에 따른 적절한 시간대의 설정이 필요하다.In particular, the use of power is changed according to weekdays, Saturdays or Sundays (holidays) in business or industrial customers, so it is necessary to set an appropriate time zone according to the weighing.
그러나 종래에는 전력량계에서 단순히 일일의 전력량만을 검칠할 수 있을 뿐이므로 칼렌다에 의거한 날짜별로 임의니 시간대를 구분 설정하여 정밀한 검침을 행할 수 없는 단점이 있었다.However, in the related art, since only a daily power amount can be read in the electricity meter, a random time zone can be set for each date based on the calendar, so that accurate meter reading cannot be performed.
이에따라 본 발명은 외부에서 복합계기의 측정시간대를 임의로 설정할 수 있도록 한 다기능 전력수급용 복합계기의 시간대 분할설정 방법을 제공함을 그 목적으로 한다.Accordingly, an object of the present invention is to provide a time zone division setting method of a multi-function power supply and demand multi-function multi-function instrument that allows to set the measurement time zone of the multi-instrument from outside.
