Description

전력 제한기Power limiter

본 고안의 실시예(3상 3선식회로)의 회로도이다.A circuit diagram of an embodiment (three phase three wire circuit) of the present invention.

본 고안은 전력 수용가가 사용하는 계약전력을 초과 사용할시 자동적 전원을 차단하고 옥내 전기 시설의 과부하나 단락등에 의한 기타 재해를 미연에 방지키 위하여 고안한 전력 제한기에 관한 것이다.The present invention relates to a power limiter designed to automatically cut off the power when exceeding the contracted power used by the power consumer, and to prevent other disasters caused by overload or short circuit of the indoor electric facility.

전기 수용가가 공급회사와의 계약 전력을 초과 허용하게 되면 지연계 전기에 의하여 수초 동안 벨 등에 의하여 초과 사용됨을 경고케 하고 지속적으로 사용할시에는 자동적으로 전원을 차단하여 전력 사용을 제한되게 하는 것이다.If the electricity customer is allowed to exceed the contract power with the supplier, the alarm will warn of excessive use by the bell, etc. for several seconds by the delay meter electricity, and in the case of continuous use, the power is automatically cut off to limit the power usage.

종래에 본 고안과 유사한 목적으로 기히 공지된 고안이 실용공보 69-856, 74-92, 76-1, 301등이 있으나 이들 공지 고안의 목적은 배선용 차단기로서 누전이나 단순이 과전류 보호용으로 정격 전류의 2.5배에서 작동하고 바이메탈 레바의 탄봉 또는 전자소자동을 구성체로 한 것이어서 신뢰성이 없고 상시 사용상태의 전력제한용에는 사용할 수가 없었다.Conventionally known designs for the purpose similar to the present invention are practical publications 69-856, 74-92, 76-1, 301, etc. However, the purpose of these known designs is a circuit breaker for short circuit or simple over current protection. It operated at 2.5 times and consisted of bimetallic levers or electronic microelectronics, so it was not reliable and could not be used for power limiting at all times.

본 고안은 상기와 같은 유사 목적 고안과는 달리 전력 수용가의 계약 전력 초과사용을 제한함으로서 배전시설의 보호와 과전류에 의한 제반사고를 미연에 방지하고 전력 절약이 될 수 있게 한 고안에 관한 것으로서 본 고안의 요지를 도면의 실시에 연관시켜 상세하게 설명하면 다음과 같다.The present invention, unlike the above-described similar purpose design, by restricting the over-consumption of the contracted power of the power consumer as a design that prevents the accident of the power distribution facility and all accidents caused by overcurrent and saves power The gist of the present invention will be described in detail with reference to the accompanying drawings.

적산 전력계 2차도선에 연결된 주개폐기(1), 다음 도선(2), (2'), (2"), 전자개폐기(3)의 접점(4), (4'), (4")을 형성하고, 도선(2), (2")에 접점(5)을 형성한 지연계전기(6)을 접속하여 도선(2)(2")에 도선 관통형 변류기을 삽입하여 전류계(7)를 연결하되 전류계(7) 내부 만자(8)(8')를 도선(9)(10)과 연결함과 동시에 지연계전기(6)과는 도선(2')으로 연결되게 한 것이다.Form the main switch 1 connected to the integrated power meter secondary conductor, the next lead 2, 2 ', 2', and the contacts 4, 4 ', 4' of the electronic switch 3 Connect the ammeter 7 by connecting the delay relay 6 having the contacts 5 to the conductors 2 and 2 ", and inserting the conductor through-type current transformer into the conductors 2 and 2 " (7) The inner pores 8 and 8 'are connected to the conductors 9 and 10 and the delay relay 6 is connected to the conductors 2'.

미설명 부호 11은 부자, 12는 누름보턴, 13, 13'는 부하축 개폐기, 14는 보지접점으로서 작동된 전자개폐기의 전원공급 접점이다.Reference numeral 11 denotes a rich, 12 pushbutton, 13, 13 'is a load shaft switch, 14 is a power supply contact of the electromagnetic switch operated as a holding contact.

이와 같은 본 고안을 실시함에 있어서, 전기 사용 상태에서 전자 개폐기(3)의 작동봉이 스프링의 힘에 의하여 접점이 통전케 된 것이어서 전자 개폐기(3) 코일을 여자하지 않고 전력공급을 함으로서 자체 전력 소모없이 부하축에 전력을 공급하는 것인데 규정된 전력을 초과 사용할시에는 전류계(7)이 규정 전류위치에 장설된 단자(8)(8') 간을 ON으로 하여 부자(11)를 울리면서 초과 사용상태에서 전자개폐기(3)가 작동되게 한 것인데 부자(11)의 경고는 지연 계전기(6)의 조정시간에 의하여 일정시간 경고하다가 초과 사용상태가 규정시간을 초과하면 계전기(6)가 작동되어 접점(5)가 접속되어 전자개폐기(3)이 여자되어 접점(4)(4')(4")은 OFF로 되고 접점(14)은 ON으로 되어 공급 전원을 차단케 되는 것이며 지연 계전기(6)은 서어지(Surge) 전류에 전자 개폐기(3)의 오동작됨이 없도록 한 것인데 전류계(7)에 장설된 단자(8)(8')간에 ON상태가 되어도 수초 동안 지연 계전기(6)은 작동이 되지 아니하며 이때 전류계(7)의 바늘이 규정 전류 이하로 내려가면 전류계(7)의 단자(8)(8')은 다시 OFF로 되어 전자 개폐기(3)의 오동작을 방지케 된 것이다.In carrying out the present invention, the operating rod of the electromagnetic switch 3 is energized by the force of the spring in the state of electric use, so that the electric switch is energized without exciting the coil of the electromagnetic switch 3 so that power is not consumed. When supplying power to the load shaft, when exceeding the specified power, the ammeter (7) turns on the terminals (8) and (8 ') installed at the specified current position and turns on the rich man (11). The electronic switch (3) is to be operated in the warning of the rich (11) is a warning for a certain time by the adjustment time of the delay relay (6), but if the over-use state exceeds the specified time, the relay (6) is operated to contact ( 5) is connected and the electromagnetic switch 3 is excited so that the contacts 4, 4 'and 4 "are turned off and the contacts 14 are turned on to cut off the power supply. The delay relay 6 Malfunction of the electronic switchgear 3 due to surge current The delay relay 6 does not operate for a few seconds even if it is turned ON between the terminals 8 and 8 'installed in the ammeter 7, and the needle of the ammeter 7 falls below the specified current. Terminals 8 and 8 'of the mask ammeter 7 are turned off again to prevent malfunction of the electromagnetic switch 3.

본 고안은 상기한 바와 같이 전기 공급시에 전력제한기 자체 전력을 소모함 없이 부하측에 전력을 공급하고 초과 사용시는 지연 계전기(6)에 의하여 수초 동안 경고하다가 수용가의 부하 줄임이 없이 지속적 초과 사용이 될 시에는 본 고안에 의하여 전원을 자동적 차단하는 것이어서 과전류로 인한 전력손실과 단락 등에 의한 사고 및 배전시설의 보호와 전력수급에 정확을 꾀할 수 있는 효과가 있다.The present invention supplies the power to the load side without consuming the power limiter itself when supplying electricity as described above, and warns for several seconds by the delay relay 6 in case of over use, and continuously overuse without reducing the load of the customer. When the power is automatically cut off by the present invention, there is an effect that can be precise in the protection and supply and demand of accidents and distribution facilities due to power loss and short circuit caused by overcurrent.
