The electrical equipment room is a component for oscillating high frequency in the food of the cooking room, and is composed of a high pressure transformer, a high pressure capacitor, a high pressure diode, a magnetron, and a cooling fan for cooling such a device. have.
상기 고압트랜스(1)의 2차코일(5)의 와이어(5a)를 접지시키기 위해서 종래에는 제1도에서 도시한 바와같이 체결공이 형성된 별도의 접지터미널(2)을 구비하고, 이 접지터미널(2)의 체결공에 스크루(7)나 리벳을 끼워 일측 E코아(3)에 체결시킨 후, 그 접지터미널(2)에 2차코일(5)의 와이어(5a)를 감은 후, 통전성을 높이기 위해 솔더링을 하여 접지시켜 구성하였다. 상기 접지터미널(2)은 또한 통전성을 위해서 주로 동편으로 형성되어 있다. 미설명부호(4)는 I코아를 나타낸 것이다.In order to ground the wire 5a of the secondary coil 5 of the high voltage transformer 1, a conventional ground terminal 2 having a fastening hole is conventionally provided as shown in FIG. 2) After tightening the screw 7 or the rivet to the E core 3 on one side, the wire 5a of the secondary coil 5 is wound around the ground terminal 2, and then the electrical conductivity is increased. It was configured by soldering to ground. The ground terminal 2 is also formed mainly on the copper side for conduction. Reference numeral 4 denotes an I core.
상기 고압트랜스(1)의 1차코일(6)과 2차코일(5)은 E코아(3)에 감겨져 있는데, 이 감겨진 코일의 권선비에 의해서 고전압이 유도되는 것이다. 즉 1차코일(6)과 2차코일(5)의 상호유도작용에 의해서 고전압이 유도되어 고압콘덴서에 인가되면, 이 인가된 고전압이 고압다이오드를 통해 정류되어 마그네트론으로 인가되어 마그네트론의 발진부에서 고주파가 발진되는 것이다.The primary coil 6 and the secondary coil 5 of the high voltage transformer 1 are wound around the E core 3, and a high voltage is induced by the winding ratio of the wound coil. That is, when a high voltage is induced and applied to a high voltage capacitor by the mutual induction of the primary coil 6 and the secondary coil 5, the applied high voltage is rectified through the high voltage diode and applied to the magnetron, where the high frequency is generated at the oscillation part of the magnetron.
