Automatic filter system of aged insulation oil for mineral oil inlet transformer in live state and its control method {APPARATUS AND METHOD FOR FILTERING AND REFINING TRANSFORMER INSULATION OIL IN LIVE WIRE}

본 발명은 활선상태에서 광유 유입변압기에 대한 노후 절연유의 자동여과정제장치 및 그 제어방법에 관한 것으로서, 사용 중인 노후 변압기의 절연유가 산화 및 산패로 인해 절연유의 색상이 짙은 갈색으로 변화되고, 전산가(0.2mgKOH/g이상)의 증가 및 내부 절연재의 경년 열화에 의한 유중가스의 증가 및 수분의 증가로 인한 총체적인 절연내력이 저하되어 전기 절연유로써의 역할을 기대할 수 없는 전기 절연유를 활선상태에서 정밀 여과 및 정제를 실시할 수 있는 장치 및 그 제어방법이다.
The present invention relates to an automatic filter agent for aging insulating oil and a control method thereof for a mineral oil inlet transformer in a live state, and the color of the insulating oil is changed to dark brown due to oxidation and rancidity. 0.2% KOH / g or more), and the overall dielectric strength is reduced due to the increase of gas in water and the increase of moisture due to the aging of internal insulation material. An apparatus capable of purifying and a control method thereof.

오늘날 전기설비가 첨단화, 대형화됨에 따라 전기설비의 사후관리 측면에 있어서 점검 및 정비의 신뢰도는 더욱더 중요하게 여기고 있다. 전기설비의 점검 및 정비는 주기성과 정밀성을 추구하는 적정성 유지의 주체로서 잠재하고 있는 전기재해의 요인을 발굴하고, 그 요인을 적정하게 제거함으로써 전기로 인한 화재 및 설비사고를 예방하는 전기안전시스템의 하나이다.As electrical facilities become more advanced and larger today, the reliability of inspection and maintenance is becoming more and more important in the aftercare aspects of electrical facilities. The inspection and maintenance of electrical facilities is the main reason for maintaining the adequacy of pursuit of periodicity and precision, and the development of electrical safety system that prevents fires and equipment accidents caused by electricity by identifying potential factors of electrical disasters and removing them appropriately. One.

따라서 전기설비에 대한 점검 및 정비의 목적은 기능과 성능을 적합하게 유지하고 사고를 미연에 방지하는데 있다고 볼 수 있다. 특히 전기설비 중 변압기는 전력계통에서 전압을 변환하는 기본적인 기능 외에 안정적인 전력공급이라고 하는 중요한 역할을 담당하고 있다.Therefore, the purpose of the inspection and maintenance of the electrical equipment is to maintain the function and performance properly and to prevent accidents. In particular, the transformer plays an important role in the stable power supply in addition to the basic function of converting voltage in the power system.

그러므로 사고 없이 기능을 충분히 발휘하기 위해서는 변압기의 신뢰성이 매우 중요하다. 그러나 정지 기기인 변압기는 사고율이 낮아 고장이 날 때까지 흔히 무시될 수 있는 취급하기 좋은 간단하고 튼튼한 전기기기이나 그 중대 사고는 장시간의 정전으로 파급 효과가 매우 크므로 전원공급의 시스템에서 가장 중요한 기기라 할 수 있다.Therefore, the reliability of the transformer is very important for full functioning without accidents. However, a transformer, a stationary device, is a simple and sturdy electrical device that can be neglected until it breaks down due to a low accident rate. It can be said.

특히 노후 된 유입변압기의 사고는 절연유의 경년열화와 전기적 사고원인이 절연유의 과열을 초래하며, 이와 같은 현상은 변압기의 화재 및 폭발사고로 이어지는 경향이 매우 높으므로 그 파급 피해는 대단히 크다.In particular, aging inflow transformer accidents cause aging of the insulating oil and overheating of the insulating oil due to electrical accidents. This phenomenon has a high tendency to lead to a fire and an explosion of the transformer.

현행 전기절연유의 품질관리기준에 따르면 전기절연유의 수분(30ppm이하) 및 절연파괴전압(30kv이상), 전산가(0.2mgKOH/g이하)와 유중가스분석에 의하여 절연유의 교체 및 여과 실시 여부를 판정하여 노후 변압기에 대한 전기절연유의 절연내력을 보강하여 운영하고 있다.According to the current quality control standards of electric insulating oils, it is determined whether to replace or filter the insulating oils by analyzing the moisture (less than 30ppm), insulation breakdown voltage (more than 30kv), acid value (less than 0.2mgKOH / g) and gas in oil. It operates by reinforcing the dielectric strength of electrical insulating oil against old transformers.

이와 같이 현재 설치되어 사용되어지고 있는 노후 변압기에 대한 전기절연유의 절연내력을 보강하기 위하여 절연유의 교체 및 여과를 실시하고자 할 때에는 그 변압기로부터 전기를 공급받는 수용가에 대한 휴전교체작업을 실시하여 수용가의 불편을 초래하는 사선교체 방법과, 내용연수에 따라 변압기를 현장에서 철거하여 변압기 수리업체에서 절연유를 교체한 후 수리된 변압기를 현장으로 다시 운반하는 과정을 거쳐 재설치하여 운전하는 공법으로, 그 절차가 복잡하고, 공사기간 및 비용이 증가되는 문제점이 있다.In order to reinforce the insulating strength of the electric insulating oil to the old transformers installed and used as described above, when the replacement and filtration of the insulating oil is to be carried out, a cease-fire replacement work for the customer supplied with the electricity is carried out. It is a method that replaces the oblique line that causes inconvenience and the method of removing and re-installing the transformer according to the service life, replacing the insulating oil by the transformer repair company, and then transporting the repaired transformer back to the site to reinstall and operate the procedure. It is complicated and there is a problem that the construction period and costs are increased.

또한 활선상태에서 절연유 교체 및 여과장치를 이용하는 방법을 사용되어 지는데, 현재 사용되어지고 있는 활선상태에서의 절연유 여과장치로서는 슬러지 및 수분여과기능에만 국한되어 일시적으로 절연파괴전압을 증가시킬 수는 있으나, 산화 및 산패에 의한 절연유의 열화가 진행되어 절연유의 특성이 변화한 것은 여과할 수 없으므로 전기절연유를 일정기간 사용한 후에는 신유에 근접한 수준의 절연유의 특성을 유지도록 전산가, 색상 및 품질을 개선할 수는 없으며, 그 절연유의 품질을 일정하게 유지할 수 있도록 실시간으로 현장에서 절연유의 특성을 측정하는 장치가 없으므로 여과된 절연유의 품질을 일정하게 계량화할 수 없는 실정이다.In addition, the method of using insulating oil replacement and filtration device in the live state is used, but the current in the active oil filtration device in the active state is limited to sludge and water filtration function, but it can temporarily increase the breakdown voltage. Changes in the characteristics of insulating oil due to oxidation and rancidity cannot be filtered. Therefore, after using electric insulating oil for a certain period of time, the computer value, color and quality can be improved to maintain the characteristics of insulating oil close to new oil. There is no device to measure the characteristics of the insulating oil in the field in real time to maintain the quality of the insulating oil is not able to quantify the quality of the filtered insulating oil constantly.

또한 전산가가 0.4(mgKOH/g)이상으로 판정되면 절연유를 신유로 교체는 비용이 발생되고, 이때에 발생되는 폐절연유의 처리에도 많은 비용이 부담되는 상황이다.
In addition, when the computational value is determined to be 0.4 (mgKOH / g) or more, the replacement of the insulating oil with a new oil is incurred, and the disposal of the waste insulating oil generated at this time is expensive.

한편, 활선상태에서 변압기의 절연유를 교체하는 장치로서 특허출원 10-2005-0087503호("활선 상태에서의 변압기 절연유 자동 공급장치 및 방법")와, 특허출원 10-2005-0081217호가 제안된 바 있다.On the other hand, Patent Application No. 10-2005-0087503 ("Automatically supplying transformer insulating oil and method in the live state") and Patent Application No. 10-2005-0081217 as a device for replacing the insulating oil of the transformer in the live state. .

도 1은 종래 활선 상태에서의 변압기 절연유 자동 공급장치의 구성도로서, 이에 도시된 바와 같이, 내부에 충전부(11)가 전기적으로 장치되고, 이 충전부(11)는 절연유(12)에 의해 충분히 잠긴 상태에서 전력을 공급하는 변압기(10)에 있어서, 일단은 상기 변압기(10) 본체 하단에 형성된 배유구(13)와 연결되고 타단은 제1펌프(41)와 연결되는 배유라인(30) 상에 수직 방향으로 설치되어 변압기(10) 본체 내부에 충진된 절연유(12)의 수위 레벨을 감지하는 절연유 감지기(20)와, 상기 절연유 감지기(20)에 의해 제1펌프(41)가 작동됨에 따라 절연유(12)가 내부로 압송되면 이를 여과하고 여과된 절연유(12)를 일시 저장하는 여과기(40)와, 일단은 상기 여과기(40)와 연결된 제2펌프(42)와 연결되고 타단은 유입구(14)와 연결된 상태에서 제2펌프(42)가 작동되면 여과된 절연유(12)를 변압기(10) 내부로 일정량 공급되게 하는 공급라인(31)과, 상기 절연유 감지기(20), 제1,2펌프(41)(42)와 전기적으로 연결되고 이를 작동 제어하는 컨트롤박스(50)로 구성되는 것을 특징으로 하는 활선 상태에서의 변압기 절연유 자동 공급 장치이다.1 is a configuration diagram of a conventional automatic transformer insulating oil supply device in a live state, as shown therein, the charging unit 11 is electrically installed therein, the charging unit 11 is sufficiently locked by the insulating oil 12 In the transformer 10 for supplying power in a state, one end is connected to the drain port 13 formed at the lower end of the main body of the transformer 10 and the other end is on the drain line 30 connected to the first pump 41. Insulating oil detector 20 installed in the vertical direction and sensing the level of the level of the insulating oil 12 filled in the transformer 10 main body, and the insulating oil as the first pump 41 is operated by the insulating oil detector 20 When the filter 12 is pumped into the inside, the filter 40 filters the oil and temporarily stores the filtered insulating oil 12, and one end is connected to the second pump 42 connected to the filter 40, and the other end thereof is the inlet 14. Filtered insulating oil 12 when the second pump 42 is operated in the Supply line 31 for supplying a predetermined amount into the transformer 10, and the control box 50 is electrically connected to the insulating oil detector 20, the first and second pumps 41, 42 and control the operation thereof The transformer insulating oil automatic supply device in a live state characterized in that it is configured.

그런데 이와 같은 종래 활선 상태에서의 변압기 절연유 자동 공급 장치는, 절연유 감지기(20)가 변압기 내부의 절연유(12)의 수위를 감지하여 여과기(40)내의 절연유를 자동으로 공급하거나 교체하는 것으로서, 단순히 변압기 내부의 절연유의 보충 및 공급과 함께 여과기능을 포함하는 정도에 지나지 않았다.By the way, the conventional automatic transformer oil supply device in the live state, as the insulating oil detector 20 detects the level of the insulating oil 12 inside the transformer to automatically supply or replace the insulating oil in the filter 40, simply transformer It only included a filtration function with replenishment and supply of internal insulating oil.

그러므로 상기와 같은 종래 활선 상태에서의 변압기 절연유 자동 공급 장치를 사용할 경우에는 기존 변압기에서 사용하던 열화정도가 심각한 절연유를 여과하고자 할 때에 종래기술은 단순한 여과기로서 절연유 중에 있는 일정크기 이상의 슬러지와 수분을 제거하는 정도로서 산화작용에 의한 전산가 및 탈취와 탈색을 실시할 수 없는 상태이다. 이와 같이 종래의 기술로는 사용 중인 기존 절연유를 신유에 근접하는 여과특성을 나타낼 수 없으며, 일정 수준으로 절연파괴전압을 상승시킬 수 있도록 슬러지의 제거 및 수분은 제거할 수 있으나 산화작용에 의한 전산가의 환원 및 탈취, 색상의 환원을 이룰 수 없으므로 절연유의 여과 후 다시 열화가 촉진되는 현상이 반복된다. Therefore, in the case of using the transformer automatic oil supply device in the conventional live state as described above, the prior art is a simple filter to remove the sludge and water in the insulating oil as a simple filter when filtering the insulation oil with severe deterioration used in the existing transformer. It is a state which cannot carry out acid value, deodorization, and discoloration by oxidation reaction. As described above, the conventional insulating oil in use cannot exhibit the filtration characteristics close to the new oil, and the sludge removal and the moisture can be removed to raise the insulation breakdown voltage to a certain level, Reduction and deodorization, color reduction can not be achieved, the phenomenon of deterioration is promoted again after filtration of insulating oil.

또한 노후 절연유의 여과정제를 실시할 때에 절연유의 절연열화정도를 검사하는 장치가 없을 뿐만 아니라, 변압기의 내부 절연유의 상부에 존재하는 오염된 공기에 포함된 수분 및 탄소 기체의 정화과정이 자동으로 이루어지지 않아 내부 절연유의 열화를 촉진하는 원인을 제공하게 된다는 결함이 있고, 최종적으로 변압기의 내부로 질소를 충진하는 과정이 생략될 수 있어서 변압기의 연속 운전 중에 변압기의 호흡작용에 의하여 외부의 수분 및 공기가 유입될 때에 내부 절연유가 외부에서 유입된 수분 및 공기와 직접 접촉되어 산화작용에 의한 절연유의 열화를 촉진한다는 문제점이 있다.In addition, there is no device for inspecting the degree of insulation deterioration of the insulating oil when performing filtration and purification of old insulating oil, and the process of purifying water and carbon gas contained in the contaminated air existing on the upper side of the insulating oil of the transformer is automatically performed. There is a defect that it does not provide a cause for promoting the deterioration of the internal insulating oil, and finally the process of filling nitrogen into the transformer can be omitted, the external moisture and air by the respiratory action of the transformer during the continuous operation of the transformer When is introduced, the internal insulating oil is in direct contact with the moisture and air introduced from the outside, there is a problem that promotes deterioration of the insulating oil due to oxidation.

본 발명은 상기에 살펴본바와 같이 현재 설치되어 운전 중인 유입변압기의 노후 된 전기절연유를 활성상태에서 절연내력을 보강하기 위하여 여과 및 정제를 실시하여 산화에 의해 열화된 절연유를 신유 수준의 절연특성을 회복할 수 있도록 함에 있어서 수반되는 문제점인 변압기의 휴전에 따른 수용가의 불편을 해소하고, 절연유의 교체에 대한 공사기간 및 비용을 절감하며, 공사절차를 간소화함과 동시에 변압기의 수명에 직접적인 관련이 있는 전기절연유의 절연특성인 전산가, 탈색, 탈취, 슬러지 및 수분 등의 절연유 특성을 신유에 근접한(80%이상)수준으로 활선상태에서 정밀 여과 및 정제를 실시할 수 있을 뿐만 아니라, 절연유의 여과 및 정제품질을 일정하게 유지할 수 있도록 하는 자동 여과정제장치와 그 제어방법을 제공하는데 목적이 있다.As described above, the present invention is to perform the filtration and purification to reinforce the insulation strength of the old electric insulating oil of the inlet transformer currently installed and operating in the active state to restore the insulating properties of the new oil level of the insulating oil deteriorated by oxidation Eliminates inconveniences of consumers due to the truce of transformers, reduces construction period and cost for replacement of insulating oil, simplifies construction procedures, and is directly related to transformer life. It is possible to perform fine filtration and refining in the live state as well as close to the new oil (80% or more) of the insulating oil properties such as acid value, decolorization, deodorization, sludge and water, which are the insulating properties of the insulating oil. It is an object of the present invention to provide an automatic filtration refining apparatus and a control method for maintaining the same.

사용 중인 노후 변압기의 절연유가 산화 및 산패로 인해 절연유의 색상이 짙은 갈색으로 변화되고, 전산가(0.2mgKOH/g이상)의 증가 및 내부 절연재의 열화에 의한 유중가스의 증가 및 수분의 증가로 인한 총체적인 절연내력이 저하되어 전기 절연유로써의 역할을 기대할 수 없는 전기 절연유를 활선상태에서 정밀 여과 및 정제를 실시할 수 있는 장치 및 그 제어방법이다.

슬러지를 제거하는 정밀여과기를 통과시켜 1u이상 슬러지를 제거한 후 신유에 근접한(80%이상) 전산가와 색상 및 물리적 품질특성을 유지할 수 있도록 조성된 정제흡착파우더필터를 3단계로 구성한 정제과정을 통해 산화과정에서 생성된 절연유 열화 물질을 제거하여 변색된 절연유의 탈색(80%이상) 및 탈취와 전산가를 환원(70%이상)하고, 진공흡입필터를 통과시켜 유중에 잔존하는 수분 및 가스를 제거하며 미세 슬러지(0.1u이상)를 여과함으로써 사용 중인 변압기를 활선상태에서 신유와 근접한 수준으로 전산가, 절연파괴전압, 수분함유량, 유전정접, 체적저항률, 악취, 색상 등의 절연내력을 환원함으로써 기존 노후 절연유를 신유로 교체하지 않는 여과정제 방법이다.
Oxidation is carried out through a three-step refining process consisting of a tablet adsorption powder filter that has been passed through a precision filter that removes sludge to remove more than 1u of sludge, and maintains the price and color and physical quality characteristics close to fresh oil (more than 80%).

이와 같이 구성되는 본 발명의 제2여과장치(800)는,The second filtration device 800 of the present invention configured as described above,

정제장치(500-700)로부터 정제된 절연유를 제5이송밸브(817)를 통해서 공급받는다. 제5이송밸브(817)의 개폐를 통해 절연유의 공급 여부를 제어하며, 공급된 절연유는 온도조절장치(801)를 통과하면서 미리 설정된 적정온도로 제어된다. 이어서 분사펌프(819)에서 미리 설정된 분사압력이 되도록 가압하여 펌핑하게 된다. 분사펌프(819)에서 펌핑된 절연유는 제6이송밸브(803)를 통해서 제1진공탱크(809) 내부에 설치된 제1진공필터장치(808)로 공급된다.The insulating oil purified from the refining device 500-700 is supplied through the fifth transfer valve 817.

The insulating oil pumped from the injection pump 819 is supplied to the first vacuum filter device 808 installed inside the first vacuum tank 809 through the sixth transfer valve 803.

이때 제1진공탱크(809)는 미리 설정된 소정의 압력으로 유지된다. 제1진공탱크(809)의 진공 압력으로 제어하는 방법은, 진공밸브(805)를 열고, 진공펌프(804)를 작동시켜 배기필터(812)를 통해 제1진공탱크(809)의 공기를 외부를 강제 배기시킴으로써 필요로 하는 압력을 유지 즉, 진공상태를 유지하게 만든다.At this time, the first vacuum tank 809 is maintained at a predetermined predetermined pressure. In the method of controlling the vacuum pressure of the first vacuum tank 809, the vacuum valve 805 is opened, and the vacuum pump 804 is operated to exhaust air from the first vacuum tank 809 through the exhaust filter 812. Forced evacuation keeps the required pressure, i.e., maintains the vacuum state.

When such a vacuum suction method is used, water and oil vapor contained in the insulating oil rise in the gas state to the upper part in the first vacuum tank 809 and the insulating oil is packed into the lower part as a liquid. At this time, the water and oil vapor rising to the upper portion of the first vacuum tank 809 is exhausted to the outside through the exhaust filter 812 by the vacuum pump 804.

그리고, 제2여과펌프(811)를 구동시켜 제1진공탱크(809) 내부에 채워진 절연유를 외부로 출력하게 된다. 이와 같이 진공 분사 여과를 거치면 수분과 가스를 제거되고, 아울러 필터에 의해 미세 슬러지도 제거된다.Then, the second filtration pump 811 is driven to output the insulating oil filled in the first vacuum tank 809 to the outside. In this way, the vacuum jet filtration removes moisture and gas, and also removes fine sludge by the filter.

또한, 활선상태에서 여과 및 정제를 위해서는 초기 기동시 신유를 변압기(100)로 보충하면서 변압기(100) 내부의 절연유를 배유시켜야 하는데, 밀봉된 드럼등에 보관된 신유일지라도 개방하여 변압기에 주유할 때 외부와의 온도차 등에 결로 현상등이 발생되면서 절연유에 수분이 함유되므로 이를 제거하기 위해서 제2여과장치(800)를 통과시켜 수분 및 잔존 가스를 제거하고 변압기(100) 내부로 주유해야한다. 따라서, 본 발명에서는 신유공급장치를 상기 제2여과장치(800)의 온도조절장치(801)의 앞단에 연결설치하고 신유 공급시 제2여과장치(800)를 구동시켜 여과처리를 하게 된다.

As described above, in order to maintain a constant internal air pressure of the transformer in the live state in the air pressure control process (S10), and to drain the internal insulating oil of the transformer 100 must be replenished with the new oil.

초기에는 변압기의 절연유를 보충하기 위하여 신유공급과정(S21)를 수행한다. 신유 충진은 진공펌프(804)를 작동시켜서 제1진공탱크(809)에 일정한 압력(예; -0.5bar)을 유지시킨다. 이어서 신유밸브(818)와 제6이송밸브(803)를 열고, 신유펌프(815)를 작동시킨다. 온도조절장치(801)를 작동시키며, 유온이 30 - 40 도를 유지하도록 온도를 제어하고, 여과온도계(802)를 통해 측정된 제1진공탱크(808) 내부 절연유의 온도 변화율이 일정해지도록 상기 온도 조절장치(801)를 제어한다.
