摘要： An IGBT module, a conductor installing structure for the IGBT module and an inverter are provided. The conductor installing structure for the IGBT module includes a substrate, a conductor and an insulation sleeve sleeved on the conductor and insulatedly isolating the conductor from the substrate. In the conductor installing structure for the IGBT module according to the present disclosure, by using the insulation sleeve sleeved on the conductor to insulatedly isolating the conductor from the substrate, the comparative tracking index of the IGBT module is improved, thereby improving the creepage distance of the IGBT module. In addition, compared with conventional technologies of spraying insulation varnish or insulation paste, the insulating property of the insulation sleeve can be better detected and guaranteed, and the bounding between the insulation sleeve and the substrate can be better enhanced, improving the insulation reliability.

摘要： A power cabinet, a grid-connected photovoltaic system and a container are provided according to the present application. In the power cabinet, three types of devices, namely, a heat dissipation element, a magnetic element, and a high-protection-level element are arranged in three mutually independent cavities, respectively; corresponding heat dissipation devices are further arranged in the three cavities respectively, and each of the heat dissipation devices meets the heat dissipation requirements of the devices in the corresponding cavity. With this arrangement, the three types of devices have their own heat dissipation solutions respectively and do not affect one another. Even if they are operated for a long time in a dusty environment, the magnetic element will not be affected by dust since the heat dissipation requirements of the three devices are satisfied in the three cavities respectively, and the reliability is improved compared with the conventional technology.
