Description
본 발명은 유니트팬을 작동하기 위한 전원공급 회로시스템에 관한 것으로, 특히 밧테리를 이용한 보조전원을 사용함에 따라 급작스런 상황에서의 주전원공급 중단이나 무가압 구간 통과시에도 유니트팬의 작동이 가능하도록 된 철도차량용 유니트팬의 작동 회로시스템에 관한 것이다.The present invention relates to a power supply circuit system for operating a unit fan, and in particular, by using an auxiliary power source using a battery, the unit fan can be operated even in a sudden situation when the main power supply is interrupted or the non-pressure section passes. It relates to an operating circuit system of a vehicle unit fan.
일반적으로 고속 전철용 및 철도차량에는 에어컨유니트가 차체의 상하에 설치되어 전장품의 냉각용으로도 사용되기 때문에 통풍팬에 전원을 공급해야하고 차체 상하가 밀폐형 덕트로 이루어져 있어 강제적인 통풍방식인 팬유니트를 채택하여 실내로 온풍 내지는 냉풍을 공급하였는데, 종래에는 에어컨 유니트를 지붕에 설치하여 도 3에 도시된 바와같이 주전원의 1500V 를 보조전원장치(11)에서 440V AC로 변환하여 유니트팬(55)으로 보내게 되면 유니트팬(55)이 작동하여 차실내로 온풍 내지는 냉풍이 유입되어진다.In general, high-speed trains and railcars have air conditioning units installed on the upper and lower sides of the car body, and are used for cooling the electrical equipment. Therefore, power must be supplied to the ventilation fan. Adopted to supply the warm air or cold air to the room, conventionally installed the air conditioning unit on the roof, as shown in Figure 3 converts 1500V of the main power supply from the auxiliary power supply 11 to 440V AC to the unit fan 55 When sent, the unit fan 55 is operated so that warm air or cold air flows into the cabin.
그러나 상기 전원공급 장치는 급작스런 상황이 진행되어 전원공급이 중단되거나 무가압 구간을 통과할 때에는 유니트팬의 작동이 되지않아 차실내로 공기조화기능이 수행되지않는 문제점이 발생하였다.However, the power supply device has a problem that the air conditioning function is not performed in the vehicle interior because the unit fan does not operate when the power supply is interrupted or when the power supply is interrupted or passes through the unpressurized section.
이에 본 발명은 상기와 같은 제반문제점을 해소하기위해 발명된 것으로, 밧테리 전원인 보조전원장치를 신설하여 절환스위치에 의해서 입력 교류 440V의 전원과 밧테리에서 출력되는 전원을 선택하여 유니트팬에 보내므로 돌발사태로 인하여 주전원 공급이 차단될 때에도 유니트팬의 작동이 가능하도록 된 철도차량용 유니트팬의 작동 회로시스템를 제공하는데 그 목적이 있다.Therefore, the present invention was invented to solve the above-mentioned problems. Since the auxiliary power supply, which is a battery power supply, was newly installed, the power supply of the input AC 440V and the power output from the battery are selected and sent to the unit fan by a switching switch. It is an object of the present invention to provide an operating circuit system of a unit fan for a railway vehicle that enables the operation of the unit fan even when the main power supply is cut off due to a situation.

상기와 같은 목적을 달성하기위한 본 발명은 주전원입력부와 유니트팬 사이에 밧테리전원과 인버터 및 변압기를 설치하고, 상기 변압기가 주전원입력부와 유니트팬과 연결이 가능하도록 절환스위치를 구비되는 구조로 된다.The present invention for achieving the above object is provided with a battery power supply and an inverter and a transformer between the main power input unit and the unit fan, and the transformer is provided with a switching switch to be connected to the main power input unit and the unit fan.
이하 본 발명을 예시도면을 참조로 하여 상세하게 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도 1은 도 1은 본 발명에 따른 팬유니트 작동을 위한 전원 공급회로도이고, 도 2는 본 발명에 따른 팬유니트 작동을 위한 전원 공급회로의 요부상세도 인바, 본 발명은; 외부로 부터 유입되어진 직류 1500 V를 440 V AC로 변환하는 주전원입력부(1)와, 직류전압을 교류전압으로 변환하는 인버터(6)와, 직류 72 V를 발생하는 밧테리전원(8)과, 밧테리전원(8)에서 내보내진 저전압을 고전압으로 승압하는 변압기(4) 및 차실내로 온풍 내지는 냉풍이 유입되도록 하는 유니트팬(5)으로 구성되어진다.1 is a power supply circuit diagram for the fan unit operation according to the present invention, Figure 2 is a main detail of the power supply circuit for the fan unit operation according to the present invention Inba, the present invention; Main power input unit 1 for converting DC 1500 V introduced from the outside into 440 V AC, inverter 6 for converting DC voltage to AC voltage, battery power source 8 for generating DC 72 V, and battery It consists of a transformer 4 for boosting the low voltage sent out from the power supply 8 to a high voltage and a unit fan 5 for introducing warm air or cold air into the vehicle interior.
여기서 상기 주전원입력부(1)와 유니트팬(5) 사이에는 절환스위치(3)가 연결되어 주전원입력부(1)의 전압과 변압기(4)의 전압을 선택적으로 유니트팬(5)에 보낼 수 있게 되고, 상기 주전원입력부(1)와 절환스위치(3) 사이와 밧테리전원(8)과 인버터(6) 사이에는 각각 퓨즈(2,7)가 연결되어진다.Here, the switching switch 3 is connected between the main power input unit 1 and the unit fan 5 to selectively transmit the voltage of the main power input unit 1 and the voltage of the transformer 4 to the unit fan 5. Fuses 2 and 7 are connected between the main power input unit 1 and the switching switch 3, and between the battery power source 8 and the inverter 6, respectively.
따라서 평상시에는 주전원입력부(1)로 부터 440 V의 전원으로 유니트팬(5)이 작동되고, 돌발사태에 의한 주전원입력부(1)에서 전원이 공급되지않을 때에는 절환스위치(3)가 밧테리전원 회로로 절환시켜 밧테리전원(8)에서 발생된 직류 전압 72 V를 인버터(6)에 공급하게 되고 이때 인버터(6)는 상기 직류전압을 교류전압으로 변환하게시켜 변압기(4)로 내보내게 되며, 여기서 상기 변압기는 유니트팬(5)이 작동가능한 3상 교류 440 V의 전압으로 승압하면서 유니트팬(5)으로 보내면, 상기 유니트팬(5)이 작동되게 된다.Therefore, the unit fan 5 is normally operated from the main power input unit 1 with a power of 440 V. When the power is not supplied from the main power input unit 1 due to an accident, the switching switch 3 is connected to the battery power circuit. Switching is supplied to the inverter 6 with a direct current voltage 72 V generated from the battery power source (8) at this time, the inverter 6 is to convert the direct current voltage to an alternating voltage to be sent to the transformer (4), wherein The transformer is sent to the unit fan 5 while the unit fan 5 is stepped up to a voltage of an operable three-phase AC 440 V, and the unit fan 5 is operated.
이상 상기에 설명한 바와같이, 돌발사태로 인하여 전원공급이 중단되거나 무가압 구간을 통과할 때에도, 유니트팬(5)에 전원이 계속적으로 공급되어 유니트팬(5)의 작동이 가능하여 쾌적한 차실내를 유지할 수 있는 효과가 있다.As described above, even when the power supply is interrupted or passes through the no-pressure section due to an accident, power is continuously supplied to the unit fan 5 so that the unit fan 5 can be operated to provide a comfortable interior. It has a sustainable effect.
