Description
본 고안은 교류전력공급설비의 버스바 감시장치에 사용되는 버스바 취부용 온도센서에 관한 것이다.The present invention relates to a bus bar mounting temperature sensor used in the bus bar monitoring device of the AC power supply equipment.
일반적으로 공장과 같은 산업용 설비에서는 3상 교류전력을 사용하게 되며 많은 양의 전력이 요구된다.In general, industrial facilities such as factories use three-phase AC power and a large amount of power is required.
따라서, 공장등의 산업시설에서는 발전소로부터 송전선로를 통하여 공급되는 수만볼트(V)의 교류전압을 대형 트랜스포머를 통하여 수천볼트의 교류전압으로 낮추어 공장의 각 설비에 공급하는 배전반을 갖추게 된다.Therefore, in industrial facilities such as factories, switchboards are provided to lower the AC voltage of tens of thousands of volts supplied from power plants through power transmission lines to AC voltages of thousands of volts through large transformers.
각 배전반에서는 고전압 대전류를 각 공장내 설비에 공급하기 위하여 통상적으로 각 설비와 배전반을 동(銅)재질의 바(BAR)로 연결하게 된다. 이와 같은 동바(銅BAR)는 일단이 배전반에 볼트 및 너트로 고정되고 타단은 설비에 역시 볼트 및 너트로 고정된다. 또한 여러개의 동바를 볼트 및 너트로 길게 연장하여 버스바로 설치사용하게 된다. 그러므로 배전반이나 각 버스바의 연결부에서는 진동이나 체결불량 등이 원인이 되어 볼트 및 너트의 조임상태가 풀릴 경우에는 전기적 접촉 불량으로 저항이 증가하게 되고 따라서 쥬울열에 의해 열이 발생하게 된다.In each switchboard, in order to supply high voltage and high current to the facilities in each plant, each facility and the switchboard are typically connected by a bar of copper material. One such bar (銅 BAR) is fixed to the switchboard with bolts and nuts and the other end is also fixed to the installation with bolts and nuts. In addition, several copper bars are extended with bolts and nuts to be used as bus bars. Therefore, when the bolts and nuts are loosened due to vibration or poor connection at the switchboard or connection part of each bus bar, the resistance increases due to poor electrical contact, and thus heat is generated by the joule heat.
이와 같은 발열현상은 화재등 큰 설비사고를 유발할 염려가 있다.Such heat generation may cause a big accident such as a fire.
따라서 버스바의 온도상승을 체크할 필요가 있는데 종래에는 각 상의 버스바에 온도감지 테이프나 온도감지 스티커를 부착하고 스티커의 온도에 따른 변색정도를 감시자나 관리자의 육안으로 감시하여 왔다.Therefore, it is necessary to check the temperature rise of the bus bar. Conventionally, a temperature sensing tape or a temperature sensing sticker is attached to each bus bar, and the degree of discoloration according to the temperature of the sticker has been monitored by the monitor or the naked eye.
그러나 이러한 종래의 감시방식은 단순히 온도상승만을 색상으로 표시할 뿐 온도상승에 따른 경보기능이 없으므로 관리 부주의 시에는 마찬가지로 대형 설비사고의 우려가 항상 내재하고 있었다.However, such a conventional monitoring method simply displays the temperature rise in color, and there is no alarm function according to the temperature rise, so there is always a concern of a large-scale equipment accident in case of carelessness.
또, 변색정도로 발열상태를 감시하여야 했기 때문에 감시나 점검자의 숙련이 요구되고 간헐적으로만 확인할 수 있어 정확한 온도를 신속하게 감지할 수 없는 문제점이 있었다.In addition, since the heat dissipation had to be monitored to a degree of discoloration, the skill of monitoring or inspector was required and it could be confirmed only intermittently, so that there was a problem in that it was not able to quickly detect an accurate temperature.
본 고안의 목적은 이와 같은 종래의 문제점을 해결하기 위하여 버스바의 온도를 검출하고 검출된 온도를 원격지에 설치된 별도의 온도감시시스템에 제공함으로써, 버스바의 점검을 용이하게 하고 정확한 온도검출과 이상 발생시 경보를 울리게 하여 대형 설비사고의 위험을 미연에 방지할 수 있게한 교류전력공급 설비의 버스바 취부용 온도센서조립체를 제공하는데 있다.The purpose of the present invention is to detect the bus bar temperature and provide the detected temperature to a separate temperature monitoring system installed at a remote location in order to solve the conventional problems. It is to provide a temperature sensor assembly for busbar mounting of AC power supply equipment that can alarm when an alarm occurs and prevent the risk of a large equipment accident in advance.
상기와 같은 목적을 달성하기 위한 본 고안은 ㄷ자 형상의 절연재질로된 조립체 본체의 일측에 버스바 삽입부를 형성하고 이 버스바 삽입부의 상부에 위치하는 상부협지편에는 온도센서수용실을 상하로 관통되게 형성하고, 상기 온도센서수용실의 상단 일측으로는 케이블안내홈을 형성한 다음 상기 센서수용실에 온도센서를 내장하여 세라믹재질의 몰딩재로 몰딩시키고 상기 케이블안내홈에 배치된 온도센서의 케이블은 에폭시계의 접착제로 몰딩시키며 상기 삽입부의 하부협지편에는 암나사부를 두어 이에 조임볼드를 나사결합하여서 구성된 특징이 있다.The present invention for achieving the above object is to form a bus bar insert portion on one side of the assembly body of the U-shaped insulating material and the upper narrow piece located on the upper part of the bus bar insert penetrates the temperature sensor chamber up and down And forming a cable guide groove on one side of the upper end of the temperature sensor accommodation chamber, and then embedding a temperature sensor in the sensor accommodation chamber to mold a ceramic molding material and to place the cable of the temperature sensor disposed in the cable guide groove. It is molded by the epoxy-based adhesive and has a feature of being configured by screwing the fastening bolt to the female threaded portion in the lower sandwich piece of the insert.

도 1, 도2, 도3에 도시된 바와 같이, 본체(10)의 일측에 버스바(22)에 취부할 수 있도록 버스바삽입부(11)가 형성되고 이 버스바삽입부(11)의 상,하부에는 상부협지편(12)과 하부협지편(13)이 마련되어 있다.As shown in Fig. 1, Fig. 2, and Fig. 3, a bus bar inserting portion 11 is formed on one side of the main body 10 so as to be mounted on the bus bar 22. An upper and lower pinched piece 12 and a lower pinched piece 13 are provided on the upper and lower parts.
상기 상부협지편(12)에는 온도센서(18)를 수용할 수 있는 온도센서수용실(14)이 마련되고 이 온도센서수용실(14)의 하단은 버스바삽입부(11)와 관통되게 형성되어 있으며, 온도센서수용실(11)의 상단은 횡방향으로 요입형성된 케이블안내홈(15)과 연통되어 있다.The upper clamping piece 12 is provided with a temperature sensor chamber 14 for accommodating the temperature sensor 18, and the lower end of the temperature sensor chamber 14 is formed to penetrate the bus bar inserting portion 11. The upper end of the temperature sensor chamber 11 is in communication with the cable guide groove 15 formed in the transverse direction.
그리고 상기 하부협지편(13)에는 암나사부(16)가 마련되어 이에 조임볼트(17)가 나사결합함으로써 삽입부(11)에 버스바(22)를 끼우고 조임볼트(17)를 조이면 버스바(22)의 표면이 상부협지편(11)의 저면에 밀착되도록 구성되어 있다.And the lower gripping piece 13 is provided with a female threaded portion 16, the tightening bolt 17 is screwed into the bus bar 22 to the insertion portion 11 and tightening the tightening bolt 17 when the bus bar ( It is comprised so that the surface of 22 may be in close contact with the bottom face of the upper pinching piece 11.
다음, 상기 온도센서수용실(11)의 내부에는 온도센서(18)를 배치하여 세라믹재질의 몰딩재(20)로 고정시키고 온도센서(18)와 연결된 케이블(19)은 케이블안내홈(15)을 따라 배치시킨후 에폭시접착제(21)로 접착하여서 된다.Next, a temperature sensor 18 is disposed inside the temperature sensor chamber 11 to fix the molding material 20 of ceramic material, and the cable 19 connected to the temperature sensor 18 is a cable guide groove 15. After arranging along, it may be adhere | attached with the epoxy adhesive 21.
상기와 같이 구성된 본 고안의 온도센서조립체는 본체(10)의 버스바삽입부(11)에 버스바(22)를 위치시킨후 조임나사(17)를 조여줌으로서 설치완료된다.The temperature sensor assembly of the present invention configured as described above is completed by placing the bus bar 22 on the bus bar insertion portion 11 of the main body 10 and then tightening the tightening screw 17.
따라서 버스바(22)의 온도는 온도센서(18)에서 감지하여 그 감지된 온도를 케이블을 통하여 온도감지시스템으로 전달케함으로써 교류전력공급설비의 온도감시체계가 이루어진다.Accordingly, the temperature of the bus bar 22 is sensed by the temperature sensor 18 and the temperature is transferred to the temperature sensing system through the cable, thereby making a temperature monitoring system of the AC power supply facility.
이와 같은 기능을 갖는 본 고안은 온도센서(18)가 세라믹재질의 센서몰딩재(20)에 의해 외부온도 및 충격으로부터 보호되고 센서몰딩재(20)내에 장착된 온도센서(18)와 케이블(19)은 다시 에폭시 재질의 접착제(21)로 본체(10)에 몰딩시키므로서 전기적 절연 상태를 유지하도록 함으로서 케이블(19)을 통한 전기적 안전사고 등을 방지할 수 있게 된다.According to the present invention having the above function, the temperature sensor 18 is protected from external temperature and impact by the sensor molding material 20 made of ceramic material, and the temperature sensor 18 and the cable 19 mounted in the sensor molding material 20. ) By molding the main body 10 with the adhesive 21 of the epoxy material to maintain the electrical insulation state it is possible to prevent the electrical safety accident through the cable (19).
이상에서와 같이 본 고안은 교류전력 공급설비에서 대전류 및 고전압을 공급하기 위한 버스바의 연결부위의 접촉불량 등으로 인한 이상 온도상승여부를 감지하고 이를 감시시스템에 전기적 신호로서 보내줌으로써 버스바의 이상 온도상승여부의 원격감시체제를 가능하게 함과 동시에 감시자의 안전사고 등을 미연에 방지할 수 있는 등의 효과가 있다.As described above, the present invention detects abnormal temperature rise due to poor contact of the connection part of bus bar for supplying high current and high voltage in AC power supply facility, and sends it as an electrical signal to the monitoring system for abnormality of the bus bar. It is possible to remotely monitor the temperature rise and to prevent the safety accidents of the monitor.
