Description
본 고안은 특고압의 전력을 저압으로 변환시켜 부하측에 필요전력을 공급하는 수배전설비에 관한 것으로, 특히, 수배전설비의 안전시설 설치비용을 절감시킬 수 있고 또한 수변전설비의 전체 설치면적을 최소화 시킬 수 있는 외부충격 보호장치를 갖는 수배전반에 관한 것이다.The present invention relates to a water distribution facility for supplying the required power to the load side by converting the power of the extra high voltage to low pressure, in particular, it can reduce the installation cost of the safety facilities of the water distribution facility, and also to reduce the overall installation area of the water The present invention relates to a switchgear having an external shock protection device that can be minimized.
잘 알려져 있는 바와 같이 수배전설비는 특고압을 저압으로 변환하여 아파트, 빌딩, 학교, 공장, 항만 등에 필요한 전력을 공급하는 전력공급 장치로서 보통 80∼700kW정도 용량을 가진다.As is well known, water distribution equipment is a power supply device that converts extra high pressure to low pressure and supplies power for apartments, buildings, schools, factories, ports, etc. and usually has a capacity of about 80 to 700 kW.
대개의 수배전설비는 변압기와 이 변압기의 최적운전제어기와 전력감시제어기 등을 포함하게 되며, 외부의 습기나 이물질 등의 유입을 차단하고 가설이 용이하도록 복층구조를 갖는 단일 함체의 고저압 일체형으로 제작된다.Most water distribution equipment includes a transformer, an optimal operation controller and a power monitoring controller of the transformer, and is a high and low voltage integrated unit of a single enclosure having a multilayer structure to block external moisture or foreign substances and to facilitate construction. Is produced.
특히, 고저압 일체형 수배전반 내부에 설치되는 전력감시제어기는 온도센서 및 전류전압 센서의 센싱값을 처리하여 고압 변압기의 가동온도, 부하율, 결상여부, 역율, 고조파율, 불평형율 등의 정보를 추출하여 해당 전력감시제어기에 장착된 LCD디스플레이를 통해 관리자에게 알려주기도 하고 또한 통신인터페이스장치를 통하여 원격지의 관리시스템에 전송하기도 한다.In particular, the power monitoring controller installed inside the high and low voltage integrated switchgear processes the sensing values of the temperature sensor and the current voltage sensor to extract information such as operating temperature, load rate, phase loss, power factor, harmonic rate, and unbalance rate of the high voltage transformer. It can be notified to the administrator through the LCD display attached to the power monitoring controller, and also transmitted to the remote management system through the communication interface device.
이러한 수배전반은 전통적으로 철판재를 이용하여 케이싱을 하고 여기에 내부 점검 및 수리를 위한 도어를 장착시키는 것이 일반적이었다. 따라서 수배전반을 점검 및 정비하기 위해서는 철판재 등으로 된 수배전반 도어를 열고 난 후에야 그 내부를 확인할 수 있었다.Such switchboards have traditionally been casing with steel plates and fitted with doors for internal inspection and repair. Therefore, in order to check and maintain the switchgear, the inside of the switchgear made of steel plate, etc., was opened only after opening.
그러나 매우 높은 특고압(22,900V)을 상용 저압(220V,380V 등)으로 변환 처리하는 수배전반 도어를 열고 그 내부를 관찰하는 것은 결국 특고압부에 점검자가 접근하는 것이 되므로 전기감전 등의 안전사고 위험이 매우 높았다.However, opening a switchgear door that converts a very high high pressure (22,900V) into a commercial low pressure (220V, 380V, etc.) and observing the inside of it will eventually approach the high voltage section, so there is a risk of safety accidents such as electric shock. Very high.
수배전반의 점검 정비를 위한 내부 모니터링의 위험성을 고려하여 최근에는 수배전반의 케이스 주변의 특정개소와 수배전반 도어에 내부를 투시하기 위한 투시창을 장착하기에 이르렀다.Considering the dangers of internal monitoring for inspection and maintenance of switchboards, it has recently been equipped with see-through windows for seeing the inside of the switchboard doors and specific parts around the case of switchboards.
또한 투시창은 그 내부에 고전압 누설전류를 픽업하여 그라운드로 바이패스시켜주기 위한 실드(그라운딩)메쉬를 적용하고 있다.In addition, the sight window employs a shielding (grounding) mesh to pick up high voltage leakage current and bypass it to ground.
도 1은 수배전반 본체(100)의 도어(110) 및 본체 주요부분에 투시창(111)을 마련하고, 이 투시창(111)에는 고전압 누설전류를 그라운드로 바이패스시켜 인명 안전사고를 방지하기 위한 실드메쉬(112)를 적용시킨 예를 보인 것이다.1 is provided with a see-through window 111 in the door 110 and the main part of the main body of the switchgear main body 100, a shield mesh for bypassing a high voltage leakage current to the ground to prevent human safety accidents An example of applying (112) is shown.
그러나 위와 같은 내부 투시용 투시창이 곳곳에 마련된 수배전반을 공사 현장에 설치하거나 차량 또는 작업자들의 이동이 빈번한 장소에 설치하게 된 경우, 작업자의 부주의 등으로 인하여 수배전반의 도어(110)에 설치된 투시창(111)이 작업도구나 시설물 또는 운반중인 자재 등에 의해 파손될 수 있다. 예를 들어, 철골조 작업자가 철근 이동중에 수배전반의 고압부 투시창을 철근의 끝단부로 타격하여 파손시킨다면 그 철근이 고압부에 그대로 진입하여 특고압을 해당 작업자에게 바로 도전시켜 감전상태에 이르게 될 수 있다.However, when installing the switchgear provided in many places such as the see-through window in the construction site in the construction site or the place where the movement of vehicles or workers are frequent, the see-through window 111 installed on the door 110 of the switchgear due to the carelessness of the worker. It may be damaged by this work tool or facility or material being transported. For example, if the steel frame worker hits the high-pressure part sight window of the switchgear at the end of the reinforcing bar while moving the reinforcing bar, the reinforcing bar enters the high-pressure part as it is, the extra high pressure can be directly challenged by the worker to the electric shock.
이러한 위험은 항상 상존하며 이를 보호하기 위해 도 2와 같이 수배전반 주변에 보호철책(120)을 이용하여 펜스를 가설하게 된다.This risk is always present and in order to protect it, a fence is constructed using a protective fence 120 around the switchboard as shown in FIG. 2.
펜스를 이용한 수배전반의 안전 대책은 수배전반의 유효설치면적의 증가와 보호철책(120)에 의한 부자재의 소요를 초래하게 되므로, 결국 수배전 시설의 설치공사 비용의 증가를 가져온다.The safety measures of the switchgear using the fence increases the effective installation area of the switchgear and the subsidiary materials required by the protective fence 120, which in turn increases the installation cost of the switchgear facility.
본 고안은 상기한 바와 같은 종래의 수배전시설 안전장치의 문제점들을 해결하기 위한 것으로, 본 고안의 목적은 수배전반에 외부인의 침입을 방지하고 또한 인명보호용 안전시설의 설치비용을 절감시킬 수 있으며, 나아가서는 수변전설비의 전체 설치면적을 최소화시킬 수 있는 외부충격 보호장치를 갖는 수배전반을 제공하는데 있다.The present invention is to solve the problems of the conventional water distribution facilities safety device as described above, the object of the present invention is to prevent the intrusion of outsiders in the switchgear and also to reduce the installation cost of safety facilities for life protection, furthermore To provide a switchgear with an external shock protection device that can minimize the total installation area of the water substation equipment.

상기 목적을 달성하기 위한 본 고안의 외부충격 보호장치를 갖는 수배전반은 수배전반 본체의 고압부 도어 및 저압부 도어의 내측에 격자형상의 도전성 안전그리드를 고정 설치하되, 이 안전그리드는 도어에 장착된 투시창보다 그 면적이 넓고 또 상기 투시창으로부터 일정간격 이격되게 설치하고, 이 도전성 안전그리드의 일측은 접지선을 이용하여 수배전반 접지에 공통 접지시켜 구성하는 것을 특징으로 한다.The switchgear having an external impact protection device of the present invention for achieving the above object is fixed to the grid-shaped conductive safety grid inside the high-pressure door and the low-pressure door of the main body of the switchgear, the safety grid than the sight glass mounted on the door The area is wide and spaced apart from the see-through window by a predetermined distance, and one side of the conductive safety grid is configured by common grounding to the switchboard grounding using a grounding wire.
첨부한 도면을 참고로 하여 본 고안을 설명하면 다음과 같다.Hereinafter, the present invention will be described with reference to the accompanying drawings.
도 3은 본 고안의 외부충격 보호장치가 마련된 펜스리스 타입 수배전반의 내부 구성도로서, 본 고안 기술적 구성의 핵심인 투시창 보호용 안전그리드를 수배전반의 고압부 또는 저압부 도어의 내측에 장착시키는 것을 보이고 있다.3 is an internal configuration diagram of a fenceless switchgear provided with an external impact protection device of the present invention, showing that the safety grid for viewing window protection, which is the core of the technical structure of the present invention, is mounted inside the high pressure part or the low pressure part door of the switchgear.
구체적으로 살펴보면, 수배전반 본체(100)의 고압부 도어 및 저압부 도어(110)의 내측에 격자 형상의 도전성 안전그리드(130)를 고정 설치한다.In detail, the grid-shaped conductive safety grid 130 is fixed to the inner side of the high pressure unit door and the low pressure unit door 110 of the switchboard main body 100.
상기 도전성 안전그리드(130)는 고압부 및 저압부의 도어(110)에 장착된 투시창(111)을 충분히 커버할 수 있는 크기로 제작되며, 상기 투시창으로부터 일정간격 이격되게 설치한다.The conductive safety grid 130 is manufactured to have a size enough to cover the see-through window 111 mounted on the door 110 of the high-pressure section and the low-pressure section, and is spaced apart from the see-through window at a predetermined interval.
상기 도전성 안전그리드(130)의 일측은 접지선을 이용하여 수배전반 접지에 공통 접지시킨다.One side of the conductive safety grid 130 is commonly grounded to the switchboard ground using a ground line.
위에서는 안전그리드(130)의 설치위치를 투시창이 마련된 수배전반의 저압부 및 고압부의 도어로 한정하여 설명하고 있으나, 반드시 도어의 투시창에만 제한적으로 설치되는 것은 아니며, 기타 수배전반의 측면에 설치되는 각 부위별 모니터링용 투시창에도 도어측의 안전그리드와 동일한 방식으로 설치될 수 있다.In the above, the installation position of the safety grid 130 is limited to the low pressure and high pressure doors of the switchgear provided with a see-through window, but the installation is not necessarily limited to the see-through window of the door, and other parts installed on the side of the switchgear. The star monitoring viewing window may be installed in the same manner as the safety grid on the door side.
이와 같이 구성된 본 고안의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above are as follows.
격자형상으로 제작되며 투시창과의 일정거리 이격을 유지를 위한 고정다리를 갖는 안전그리드(130)는 수배전반의 고압측 및 저압측 도어(110)에 형성된 투시창(111)과 각종 수배전반 내부 모니터링을 위한 측면 투시창들을 감싸는 형태로 수배전반 내측으로 고정 설치되고 있기 때문에, 기존의 수배전반의 외형 사이즈의 증가는 가져오지 않는다.The safety grid 130 is manufactured in a grid shape and has a fixed leg for maintaining a predetermined distance from the viewing window. The safety grid 130 is formed on the high and low pressure doors 110 of the switchgear and the side for monitoring various switchboards. Since the see-through windows are fixedly installed inside the switchboard, there is no increase in the external size of the existing switchboard.
이렇게 수배전반 본체(100)의 투시창(111)마다 안전그리드가 설치되어 있어, 공사현장이나 전력공급실 등에서 작업자 또는 관리자의 부주의로 인하여 임의의 기구물에 의해 고압부 도어 등에 설치된 투시창(111)이 파손되는 우발적인 사고가 발생하더라도, 해당 기구물의 끝단부가 그 파손된 투시창의 내측으로 설치된 안전 그리드(130)에 의해 더 이상의 진입이 억제되어, 고압부와 작업자의 기구물의 접촉될 가능성이 원천적으로 방지된다.In this way, safety grids are installed in each of the see-through windows 111 of the switchboard main body 100, and accidental damages to the see-through windows 111 installed on the high-pressure part doors due to arbitrary mechanisms due to carelessness of workers or managers in construction sites or power supply rooms. Even if an accident occurs, further entrance is suppressed by the safety grid 130 installed inside the broken viewing window, so that the possibility of contacting the high pressure part with the worker's device is fundamentally prevented.
따라서, 공사현장 등에서 작업자 등에 의한 관리소흘 및 부주의로 인한 안전사고의 발생 가능성이 현저히 줄어들게 된다.Therefore, the likelihood of a safety accident due to carelessness and carelessness by workers or the like at the construction site is significantly reduced.
또한 본 고안의 안전그리드(130)는 수배전반에 대한 안전유지를 위해 접근 금지용 보호철책(120)에 의한 펜스를 설치하는 것을 강제하지 않게 된다. 이것은 보호철책(120)의 철거 내지는 삭제를 가능하게 하므로 수배전 설비의 설치비용의 절감효과와 설치소요면적의 축소를 가능하게 한다.In addition, the safety grid 130 of the present invention is not to force the installation of the fence by the prohibition protection fence 120 for maintaining safety for the switchgear. This enables the removal or deletion of the protective fence 120, thereby reducing the installation cost and reducing the installation area of the water distribution facility.
이상에서 설명한 바와 같은 본 고안의 외부충격 보호장치를 갖는 수배전반은 수배전설비의 구축시 불특정 접근자에 대한 인명보호 및 외부인에 대한 설비보호용 안전시설의 설치비용을 절감시킬 수 있는 특유의 효과를 가져온다.The switchgear having the external shock protection device of the present invention as described above has the unique effect of reducing the installation cost of the safety facility for protecting the life and protection of unspecified accessors and the protection of outsiders when constructing the distribution system. .
또한 본 고안은 수배전반 보호를 위한 별도의 보호철책을 필요로하지 않게 되므로 수변전설비의 전체 설치면적을 최소화 시키는 효과도 가져온다.In addition, the present invention does not require a separate protective fence for the protection of the switchgear brings the effect of minimizing the entire installation area of the water substation facility.
