Temperature rise and structural characteristics of box transformers
A box-type substation is a prefabricated, compact electrical equipment that assembles high-voltage switchgear, distribution transformers and low-voltage electrical devices according to a certain wiring method. With the development of economy and the acceleration of urbanization, box-type substations like this one have the characteristics of strong complete set, small size, compact structure, safe and reliable operation, convenient maintenance, less investment, quick effect, and short power transmission cycle. It is widely used in urban and rural power grids. Especially due to urban planning, land

What should be paid attention to in the installation of box-type substations
The correct installation of the box-type transformer is the key to the correct use of the equipment in the subsequent process. Following the operation instructions can avoid vague failures due to improper installation during use, and reduce the frequency of downtime for maintenance. 1. The box transformer is mainly composed of natural wind and circulating cooling. Therefore, there should be no illegal stacking around it, especially the transformer room door should not be blocked, and the shutters should be regularly removed for ventilation and the attachments on the sub-holes to ensure that all electrical equipment does not exceed the allowable temperature. 2. Box type changer
