본 고안은 전자렌지의 고전압트랜스 보호용 휴즈장착구조에 관한 것으로, 특히 고전압트랜스의 영전위단의 접지사이에 저전압휴즈를 접속하는 전자렌지의 고전압트랜스보호용 휴즈장착구조에 관한 것이다.The present invention relates to a fuse mounting structure for protecting a high voltage transformer of a microwave oven, and more particularly, to a fuse mounting structure for protecting a high voltage transformer of a microwave oven connecting a low voltage fuse between grounds of a zero potential terminal of a high voltage transformer.

종래의 전자렌지의 마그네트론구동회로는 제1도에 도시한 바와 같이 고전압트랜스(T1)는 도시하지 않은 교류전원단으로 부터 공급되는 상용교류전원(약 : 240V)을 1차코일단(1)으로 인가받아 2차코일단(5)으로 고전압교류전원(약 : 2200V)을 출력하고, 필라멘트코일단(3)에 저전압교류전원(약 : 3.4V)을 출력시킨다.In the conventional magnetron driving circuit of the microwave oven, as shown in FIG. 1, the high voltage transformer T1 receives a commercial AC power supply (approximately 240 V) supplied from an AC power supply terminal (not shown) as the primary coil stage 1. A high voltage AC power supply (about: 2200V) is output to the secondary coil stage 5, and a low voltage AC power supply (about: 3.4V) is output to the filament coil stage 3.

또한, 고전압콘덴서(C1)는 2차코일단(5)으로 출력되는 고전압교류전원을 충, 방전시키는 소자이고, 고전압휴즈(6)는 일측이 상기 고전압트랜스(T1)의 고압단(5a)에 타측이 상기 고전압콘덴서(C1)에 연결되어 마그네트론(Q1), 또는 고전압다이오드(D1)의 쇼트시 강기 고전압트랜스(T1)의 2차코일단(5)에 과전류가 흐를때 차단되어 상기 고전압트랜스(T1)를 보호하는 역할을 하며, 고전압다이오드(T1)는 상기 고전압교류전원의 양의 반주기 동안에 도통되고, 음의 반주기 동안에 차단되는 고전압정류다이오드이며, 상기 고전압콘덴서(C1)와 고전압다이오드(D1)가 배전압정류부를 형성하여 상기 2차코일단(5)으로 부터 출력되는 고전압교류전원(약 : 2200V)을 마그네트론(Q1)의 에노드(ANODE)에 공급하기 위한 고전압직류전원으로 변환한다.In addition, the high voltage capacitor (C1) is a device for charging and discharging the high voltage AC power output to the secondary coil stage (5), one side of the high voltage fuse (6) is the other side to the high voltage terminal (5a) of the high voltage transformer (T1). It is connected to the high voltage capacitor (C1) is cut off when the overcurrent flows to the secondary coil stage (5) of the strong high voltage transformer (T1) when the magnetron (Q1) or the high voltage diode (D1) is short-circuited, so The high voltage diode (T1) is a high voltage rectifying diode that is conducted during a positive half cycle of the high voltage AC power supply and is cut off during a negative half cycle, and the high voltage capacitor (C1) and the high voltage diode (D1) are doubled. A voltage rectifier is formed to convert the high voltage AC power (about 2200 V) output from the secondary coil stage 5 into a high voltage DC power supply for supplying the anode ANODE of the magnetron Q1.
