    济南新万博登录网址万博官网app下载:新万博登录网址能稳定工作,必须确保新万博登录网址运行环境满足其所规定容许环境。

    Jinan Inverter Maintenance: Inverter can work steadily, it must ensure that the operating environment of the converter meets its allowable environment.

    1. 安装场所:

    1. Installation site:

    1: 电气室应湿汽少、无水浸2: 无爆炸性、燃烧性或腐蚀性气体和液体,粉尘少3: 万博官网app下载检查容易进行4: 应备有通风口或换气装置以排出新万博登录网址产生热量2. 使用条件:

    1: Electrical chamber should have less moisture, no water immersion 2: no explosive, burning or corrosive gases and liquids, less dust 3: Maintenance inspection is easy to carry out 4: Ventilation or ventilation device should be equipped to discharge the heat generated by frequency converter 2. Use conditions:

    1: 新万博登录网址运行温度多为:0~40或-10~50,要注意新万博登录网址柜体通风性。

    1: Frequency converter operating temperature is mostly 0-40 or-10-50, attention should be paid to the ventilation of the converter cabinet.

    2: 新万博登录网址周围湿度为90%以下。周围湿度过高,存电气结缘降低和金属部分腐蚀问题。受安装场所限制,新万博登录网址不已安装湿度高场所,新万博登录网址柜体应尽量采用密封结构。为防止新万博登录网址停止时结露,装置需加对流加热器。

    2: The humidity around the frequency converter is below 90%. High ambient humidity, low electrical junction and corrosion of metal parts. Due to the limitation of installation site, the frequency converter has not been installed in high humidity places, so the cabinet of the frequency converter should adopt sealed structure as far as possible. In order to prevent condensation when frequency converter stops, convection heater is needed in the device.

    3: 新万博登录网址周围不应有腐蚀性、爆炸性或燃烧性气体以及粉尘和油雾。新万博登录网址安装周围如有爆炸性和燃烧性气体,新万博登录网址内有易产生火花继电器和接触器,会引起火灾或爆炸事故。有腐蚀性气体时,金属部分产生腐蚀,影响新万博登录网址长期运行。新万博登录网址周围存粉尘和油雾时,这些气体新万博登录网址内附着、堆积将导致结缘降低;强迫风冷新万博登录网址,过滤器堵塞将引起新万博登录网址内温度异常上升,致使新万博登录网址不能稳定运行。

    3: There should be no corrosive, explosive or combustible gas, dust and oil mist around the frequency converter. If there are explosive and burning gases around the installation of frequency converter, there are spark relays and contactors in the frequency converter, which will cause fire or explosion accidents. When there is corrosive gas, the metal part will corrode, which will affect the long-term operation of the frequency converter. When dust and oil mist are stored around the converter, the attachment and accumulation of these gases in the converter will lead to the decrease of the junction; when forced air-cooled converter is blocked, the temperature in the converter will rise abnormally, resulting in the unstable operation of the converter.

    4: 新万博登录网址耐振性应机种而不同,振动超过新万博登录网址容许值时,将产生部件紧固部分松动以及继电器和接触器等可动部分器件误动作,往往导致新万博登录网址不能稳定运行。机床、船舶等事先能预见振动场合,应考虑新万博登录网址振动问题。

    4: The vibration resistance of frequency converter varies according to the type of machine. When the vibration exceeds the allowable value of frequency converter, it will result in the loosening of the fastening part of components and the misoperation of movable parts such as relays and contactors, which often leads to the unstable operation of frequency converter. The problem of frequency converter vibration should be considered when machine tools, ships and other vibration situations can be predicted beforehand.

    5: 新万博登录网址标高多规定1000m以下。标高高则气压下将,容易产生结缘破坏。另外标高高冷却效果也下降,必须注意温升。

    5: The elevation of frequency converter is usually less than 1000m. The elevation will lead to the failure of the bond under the atmospheric pressure. In addition, the cooling effect of elevation decreases, so we must pay attention to temperature rise.

    新万博登录网址接线:

    Converter wiring:

    各种工厂和设备采用变频调速时,新万博登录网址电源侧和电机侧都会产生 谐波干扰,对供电电网和新万博登录网址周围其他电气设备要产生EMC干扰。另外确保新万博登录网址长期可靠运行,新万博登录网址接线是非常重要。

    When various factories and equipments adopt frequency conversion speed regulation, harmonic interference will occur on the power side and motor side of the converter, and EMC interference will occur on the power supply grid and other electrical equipment around the converter. In addition, to ensure the long-term reliable operation of the converter, the connection of the converter is very important.
