특고압 밀폐형 수변전 장치{HIGHVOLTAGE METALCLAD TYPE SWITCHGEAR}Extra High Pressure Sealed Water Transformers {HIGHVOLTAGE METALCLAD TYPE SWITCHGEAR}

본 발명은 특고압 밀폐형 수변전 장치에 관한 것으로서, 보다 구체적으로는 SF6로 충전된 특고압부의 밀폐부로부터 기체 내 포함된 수분을 제거하기 위한 특고압 밀폐형 수변전 장치에 관한 것이다.The present invention relates to an extra-high pressure sealed water transformer device, and more particularly, to an extra-high pressure sealed water transformer device for removing moisture contained in gas from the sealed portion of the extra-high pressure part filled with SF 6 .

일반적으로 학교, 빌딩, 아파트단지, 공장 등과 같은 집단 전력수요처에서는 각각이 필요로 하는 전력을 얻기 위해 변전소로부터 예컨대 22,900V의 특고압 전력을 수전하여 예컨대 220V와 같은 저전압으로 변전하는 수변전 장치를 갖추고 있다. 이러한 수변전 장치는 특고압을 수전하는 부분(수전반), 특고압을 저압으로 변압하는 부분(변전반), 및 낮추어진 전압을 아파트 등 각 수용처로 분배하는 부분(분전반)으로 나눌 수 있으며, 수전반은 예컨대 특고압 케이블과 연결되어 수변전 장치의 인입구 역할을 하는 부하개폐기(LBS), 특고압 기기의 단락보호용 퓨즈인 전력퓨즈(PF), 전력량을 측정하기 위해 특고압을 저압으로 변성하는 계기용 변성기(MOF), 단락과 같은 이상발생시 전압을 차단하는 진공차단기(VCB) 등으로 구성되어 있다. 상기와 같은 종래 수변전 장치는 대형 변압기를 중심으로 수전반을 구성하는 부하개폐기(LBS), 전력퓨즈(PF), 계기용 변성기(MOF), 진공차단기(VCB) 등의 장치들과 관련계기가 평면적으로 배치되어 있고, 또한 감전사고 등의 안전을 고려하여 전반 내부에서도 장치간의 충분한 이격거리를 유지시켜야 하므로 수전반을 포함하는 수변전 장치를 설치하는데 넓은 설치면적이 요구되었고, 이에 따라 설치비용의 증가를 초래하였다.In general, group power demands such as schools, buildings, apartment complexes, factories, etc. are equipped with substations that receive extra high voltage power of 22,900 V from substations and convert them to low voltages, for example 220 V, in order to obtain the required power. have. Such a water substation device may be divided into a part for receiving a high voltage (a power panel), a part for transforming a high voltage to a low pressure (station), and a part for distributing a lowered voltage to each accommodation such as an apartment (distribution panel). The power panel is connected to a special high voltage cable, for example, a load switch (LBS) serving as an inlet of a water substation device, a power fuse (PF) which is a short-circuit protection fuse of an extra high voltage device, and a high voltage to low voltage to measure power. Instrument transformer (MOF), vacuum breaker (VCB) that cuts off the voltage in case of abnormality such as short circuit. The conventional water substation apparatus includes devices such as a load breaker (LBS), a power fuse (PF), an instrument transformer (MOF), and a vacuum circuit breaker (VCB) constituting a power switchboard with a large transformer as its center. Since it is arranged in a planar manner and sufficient distance between devices is to be maintained in the first half in consideration of safety such as electric shock accident, a large installation area was required to install a water substation device including a power panel. Resulted in an increase.
