본 발명은 변전소 운영상태 감시를 위한 디지탈 축소형 모자익 배전반에 관한 것으로서, 특히 임의의 지역에 설치된 변전소에 구성되어 있는 다수의 차단기의 동작상태를 모자이크장치의 전면패널에 설치된 각종 표시램프를 통해 한눈에 확인할 수 있고, 또한 전면패널에 구비된 제어스위치를 이용하여 현장에 설치된 차단기를 원격제어할 수 있으며, 모자이크장치와 현장정보처리반을 광케이블로서 연결하여 현장과 모자이크처리반이 통신방식으로 데이타를 공유함에 따라 시설 설치비 및 유지 보수비용을 절약할 수 있도록 한 변전소 운영상태 감시를 위한 디지탈 축소형 모자익 배전반에 관한 것이다.The present invention relates to a digital reduced-capacity switchgear for monitoring the operation status of a substation. In particular, the operation state of a plurality of circuit breakers configured in a substation installed at an arbitrary area can be viewed at a glance through various display lamps installed on the front panel of the mosaic device. You can check and also remote control the breaker installed in the site by using the control switch provided on the front panel, and connect the mosaic device and the field information processing panel with the optical cable so that the field and the mosaic processing panel share the data by communication method. The present invention relates to a digital reduced-capacity switchgear for monitoring the operation status of substations to save facility installation and maintenance costs.

일반적으로 각 가정이나 사무실 등에서 사용되는 전기는 각 지역별로 설비되어 있는 변전소로부터 제공되고 있다. In general, electricity used in each home or office is provided by substations installed in each region.

즉, 변전소는 발전소에서 생산한 전력을 송전선로나 배전선로를 통하여 수용가에게 보내는 과정에서 전압이나 전류의 변성 및 전력의 배분을 위하여 설치되는 시설이라 할 수 있으며, 상기 변전소는 154KV, 23KV용 현장설비로 나뉘어지며, 23KV 변전소를 통해 각 부하(소비자)로 전기가 공급된다.In other words, the substation is a facility that is installed for the distribution of voltage or current and the distribution of power in the process of sending the power produced by the power plant to the customer through the transmission line or distribution line, the substation is a field equipment for 154KV, 23KV It is divided and supplied to each load (consumer) through a 23KV substation.

그리고, 각각의 변전소에는 부하측으로 전기를 공급하는 도중 단락이나 지락 상태일때 시설물을 보호하기 위하여 전선로를 차단하는 복수개의 차단기가 설치된다.In addition, each substation is provided with a plurality of circuit breakers for disconnecting the electric wires in order to protect the facility when a short circuit or ground fault occurs while supplying electricity to the load side.

상기 설명과같이 변전소에는 수용가로 전기를 안정적으로 공급하기 위한 아주 복잡한 설비가 갖추어지게되며, 이러한 변전소에 설치된 차단기와 같은 각종 장치의 동작상태를 모니터링하여 고장의 징후를 미리 발견하여 대비하거나 아니면 발생된 고장에 신속히 대응하여 복구할 수 있도록 모니터링시스템이 제공되고 있다.As described above, the substation is equipped with a very complicated facility for stably supplying electricity to the customer, and monitors the operation state of various devices such as a circuit breaker installed in the substation in advance to detect and prepare for the signs of failure or Monitoring systems are being provided to quickly recover from failures.

종래의 모니터링시스템은 현장기기, 즉, 현장에 설치된 각종 차단기 및 그밖의 장치들과 메인관리시스템을 각각 독립적인 케이블로 연결하여 메인관리시스템에서 변전소의 현장기기 동작상태를 모니터링하도록 구성되어 있다.Conventional monitoring system is configured to monitor the field equipment operation status of the substation in the main management system by connecting each device, that is, various circuit breakers and other devices installed in the site and the main management system with independent cables.

그러나, 종래기술은 현장기기와 메인관리시스템을 1대1 대응되도록 케이블로서 연결하여 아날로그적으로 데이타를 송신하는 구조이기 때문에 변전소와 메인관리시스템의 거리가 멀어질 수록 시설 설비비가 상승하게되고, 또한 현장기기의 동작상태를 모니터링하기 위해서는 수천가닥의 케이블이 현장기기와 메인관리시스템 사이에 연결되어야만 하므로 설비가 매우 복잡해질 뿐만 아니라 어느 한 라인이 고장나게되면 전체 라인중에서 고장난 부분을 찾아내기가 어려워 고장 복구에 많은 시간이 소요되는 문제점이 발생하고 있었다.However, since the conventional technology is a structure that transmits data analogously by connecting the field equipment and the main management system as a cable to one-to-one correspondence, the facility equipment cost increases as the distance between the substation and the main management system increases. In order to monitor the operation status of field equipment, thousands of cables must be connected between the field equipment and the main management system, which not only makes the facility very complicated, but it also makes it difficult to find the fault in the entire line when one line fails. There was a problem that took a long time to recover.

따라서, 상기 문제점을 해결하기 위한 본 발명은 변전소 현장기기와, 상기 현장기기로부터 제공되는 계전기 동작 및 경보, 현장설비 상태감지신호 등을 공급받아 RTU-FPD 및 모자이크장치로 송신하고, RTU-FPD 또는 모자이크장치로부터 송신된 현장기기 제어신호를 현장기기로 공급하는 현장정보처리반과, 상기 현장정보처리반에서 송신되는 각종신호를 RTU-MPD를 통해 메인관리센터(SCADA)로 송신하는 RTU-FPD와, 전면에 현장기기의 결선상태를 축소하여 한눈에 볼수있도록 전면패널이 형성되고 상기 현장정보처리반과 광케이블로 연결되어 현장정보처리반으로부터 제공되는 변전소의 경보, 상태, 제어신호에 따라 전면패널에 설치된 각종 램프를 점등함과 동시에 차단기의 동작횟수를 카운팅하여 표시하는 모자이크장치로 구성하므로서, 임의의 지역에 설치된 변전소에 구성되어 있는 다수의 차단기의 동작상태를 모자이크장치의 전면패널에 설치된 각종 표시램프를 통해 한눈에 확인할 수 있고, 또한 전면패널에 구비된 제어스위치를 이용하여 현장에 설치된 차단기를 원격제어할 수 있으며, 모자이크장치와 현장정보처리반을 광케이블로서 연결하여 현장과 모자이크처리반이 통신방식으로 데이타를 공유함에 따라 시설 설치비 및 유지 보수비용을 절약할 수 있도록 한 변전소 운영상태 감시를 위한 디지탈 축소형 모자익 배전반을 제공함을 목적으로 한다.Accordingly, the present invention for solving the above problems is to receive the substation field device, the relay operation and alarm provided from the field device, the field equipment status detection signal and the like transmitted to the RTU-FPD and mosaic device, RTU-FPD or An on-site information processing unit for supplying the on-site device control signal transmitted from the mosaic device to the on-site device, an RTU-FPD for transmitting various signals transmitted from the on-site information processing unit to the main control center (SCADA) through the RTU-MPD; The front panel is formed to reduce the wiring state of the field equipment at a glance, and the various lamps installed on the front panel according to the alarm, status, and control signal of the substation provided from the field information processing panel connected to the field information processing panel and the optical cable. Installed in an arbitrary area by constructing a mosaic device that lights up and counts the number of breakers You can check the operation status of multiple circuit breakers in the substation at a glance through various indicator lamps installed on the front panel of the mosaic device. Also, you can remotely control the circuit breakers installed in the site by using the control switch provided on the front panel. It is a digital miniature switchgear for monitoring the operation status of substations, which connects the mosaic device and the field information processing panel as optical cables so that the site and the mosaic processing panel share data by communication method. For the purpose of providing it.
