Description

EDG 종합성능시험용 단자대 점퍼 장치{Terminal Block Jumper Device for Comprehensive Performance Test of Emergency Diesel Generator}Terminal Block Jumper Device for Comprehensive Performance Test of Emergency Diesel Generator}

본 고안은 발전소에 설치되어 있는 EDG(Emergency Diesel Generator, 비상디젤발전기)의 성능시험 장비에 관한 것으로, 더욱 상세하게는 EDG 종합성능시험용 단자대 점퍼 장치에 관한 것이다.This design relates to performance test equipment for EDG (Emergency Diesel Generator) installed in a power plant, and more specifically, to a terminal jumper device for EDG comprehensive performance testing.

발전소에 설치되어 있는 EDG는, 공학적 안전설비 부하들에 연결된 외부전원이 상실되었을 때 전력을 공급하고 각 호기마다 100%용량 2대의 디젤 발전기가 설치되어 있다. The EDG installed in the power plant supplies power when the external power connected to the engineering safety equipment loads is lost, and two diesel generators with 100% capacity are installed in each unit.

이러한 EDG는, 외부전원 상실 시(LOOP)나 안전주입신호(SIAS) 발생시 Class-1E 부하에 전원을 공급하여 원자로를 확실하게 정지시키는데 필요한 모든 공학적 안전설비 부하에 전원을 공급하는데, 계획예방정비 후, 운영기술지침서 점검요구 사항을 만족하는지 입증하기 위한 시험을 수행하게 된다. This EDG supplies power to Class-1E loads when external power is lost (LOOP) or when a safety injection signal (SIAS) occurs, supplying power to all engineering safety equipment loads necessary to safely stop the nuclear reactor, after planned preventive maintenance. , a test will be conducted to verify whether the inspection requirements of the operating technology guidelines are met.

구체적으로, 1)계획예방정비 후 비상디젤발전기가 운영기술지침서 점검요구 사항을 만족하는지 입증하기 위한 시험을 위해, Hi-Speed Recorder를 설치하여 운전 변수를 취득하고 발전기 권선온도, 베어링온도, 출력, 전압, 주파수를 오프라인으로 취득한다.Specifically, 1) In order to test to verify whether the emergency diesel generator satisfies the inspection requirements of the operation technology guideline after planned preventive maintenance, a Hi-Speed Recorder is installed to acquire operating variables and measure the generator winding temperature, bearing temperature, output, Obtain voltage and frequency offline.

그리고 2)소외전원 상실시험(LOOP-Step1) 단계에서 비상정지 신호에 의한 락 아웃(Lock-Out) 기능시험 절차에서 신호주입을 위해 인접케이블에 접촉되지 않도록 주의하면서 단자를 점퍼한다. And 2) in the lock-out function test procedure using an emergency stop signal in the external power loss test (LOOP-Step1) stage, jumper the terminal while being careful not to contact adjacent cables for signal injection.

또한, 3)비상디젤발전기가 기동되지 않음을 확인 후 공학적안전설비 작동신호(ESFAS-SIAS)에 의한 비상디젤발전기 시험(Step2) 단계에서 EDG Load Seq’로 구동 후 모선 차단기가 트립되는지 확인한다. Additionally, 3) After confirming that the emergency diesel generator does not start, drive it with EDG Load Seq’ in the emergency diesel generator test (Step 2) stage using the engineering safety equipment operation signal (ESFAS-SIAS) and check whether the bus breaker trips.

그리고 4)공학적 안전설비 작동신호(ESFAS)를 동반한 소외전원 상실신호(LOOP)에 의한 시험(ESFAS+ LOOP-Step3) 단계는 단일 취대부하 제거 시험 후 트립 우회 확인 시험으로 다음 표의 단자를 점퍼하여 작업 수행 후 경보가 발생되고 발전기가 정지되지 않음을 확인하고 시험 무효화 시험 24시간 부하운전시험(Step 4) ,고온재기동(Step 5), 부하차단 시험 및 시험 후 점검 (Step 6)의 단계로 시험을 진행한다.And 4) the test (ESFAS+ LOOP-Step 3) using the off-site power loss signal (LOOP) accompanied by the engineering safety equipment operation signal (ESFAS) is a trip bypass confirmation test after a single stand-up load removal test, and is performed by jumpering the terminals in the following table. After performing the test, confirm that an alarm is generated and the generator does not stop, and the test is performed in the following steps: test invalidation test, 24-hour load operation test (Step 4), high temperature restart (Step 5), load disconnection test, and post-test inspection (Step 6). Proceed.

이때, 소외전원상실시험(LOOP-Step1) 단계에서 비상정지 신호에 의한 락 아웃(Lock-Out) 기능시험 절차에서 신호주입을 위해 단자대 점퍼작업 수행을 하는데 인접 케이블에 접촉되지 않도록 클립으로 만든 점퍼선으로 주의하면서 단자를 점퍼하게 되는데, 수회의 반복되는 현장 판넬에서의 점퍼 작업은 단자대가 인접 케이블에 가려져 클립으로 점퍼 작업시 애로 사항이 있고 점퍼 후 수초 동안 사람의 손가락으로 현상유지를 하고 있어야 해서 손 떨림에 의한 채터링 현상이 발생할 수 있다. At this time, in the lock-out function test procedure using an emergency stop signal in the external power loss test (LOOP-Step1) stage, terminal jumper work is performed for signal injection, and the jumper wire is made with a clip to prevent contact with adjacent cables. The terminals are jumpered with caution, but the jumper work in the field panel, which is repeated several times, causes difficulties when working on the jumper with a clip because the terminal block is covered by an adjacent cable, and the status quo must be maintained with a person's finger for several seconds after the jumper, which requires manual labor. Chattering due to tremor may occur.

본 고안은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로서, 본 고안의 목적은, EDG 종합성능시험 중 단자대 점퍼 작업 시, 반복되는 현장 판넬에서의 점퍼 작업시 수초 동안 사람의 손가락 힘 대신 점퍼 장치의 손잡이로 현상 유지를 하여 채터링 현상이 발생하는 것을 방지하고, 혼촉 방지용 판을 점퍼 작업 전에 해당 단자대만 노출되도록 하여 인적 오류를 최소화할 수 있는 EDG 종합성능시험용 단자대 점퍼 장치를 제공함에 있다.The present invention was created to solve the above problems, and the purpose of the present invention is to use the jumper device instead of the force of a person's fingers for several seconds when working on a terminal board jumper during an EDG comprehensive performance test or when working on a jumper in a field panel repeatedly. We provide a terminal block jumper device for EDG comprehensive performance testing that prevents chattering by maintaining the status quo with a handle and minimizes human errors by using the anti-contact plate to ensure that only the relevant terminal block is exposed before jumper work.

And the terminal portion includes a terminal contact pin portion connected to the terminal block of the emergency diesel generator; and a clip portion provided at the bottom of the terminal contact pin portion, allowing the terminal portion to be fastened to the housing or side wall of the terminal block of the emergency diesel generator.

또한, 단자 접촉핀부는, 끝단에 바나나 형상으로 형성되는 바나나 잭이 구비될 수 있다. Additionally, the terminal contact pin portion may be provided with a banana jack formed in a banana shape at the end.

그리고 단자 접촉핀부는, 몸체의 중간에 스프링이 마련되어, 비상용 디젤발전기의 단자대에 연결되는 경우, 스프링의 압력 작용으로 단자대와의 접촉력이 유지되도록 할 수 있다. In addition, the terminal contact pin portion is provided with a spring in the middle of the body, so that when connected to the terminal block of an emergency diesel generator, the contact force with the terminal block can be maintained by the pressure of the spring.

또한, 클립부는, 단자대의 하우징 또는 측벽에 결착되는 경우, 고정력이 향상되도록, 내측에 미끄럼 방지 패드(non-slip pad)가 마련될 수 있다. Additionally, when the clip portion is attached to the housing or side wall of the terminal block, a non-slip pad may be provided on the inside to improve fixing force.

이상 설명한 바와 같이, 본 고안의 실시예들에 따르면, EDG 종합성능시험 중 단자대 점퍼 작업 시, 반복되는 현장 판넬에서의 점퍼 작업시 수초 동안 사람의 손가락 힘 대신 점퍼 장치의 손잡이로 현상 유지를 하여 채터링 현상이 발생하는 것을 방지하고, 혼촉 방지용 판을 점퍼 작업 전에 해당 단자대만 노출되도록 하여 인적 오류를 최소화할 수 있다.As described above, according to the embodiments of the present invention, when working on a terminal board jumper during an EDG comprehensive performance test, or when working on a jumper on a field panel repeatedly, the status quo is maintained with the handle of the jumper device instead of the force of a person's finger for several seconds to prevent chatter.
