Mobile transformer substation

Abstract

The invention discloses a mobile transformer substation. The mobile transformer substation is connected with a commercial power terminal and a user terminal. The mobile transformer substation comprises a mobile vehicle and a transformer, the interior of a carriage of the mobile vehicle is divided into a low-voltage chamber, a transformer chamber and a high-voltage chamber, the transformer is arranged in the transformer chamber, the mains supply end is arranged in the high-voltage chamber, the user terminal is arranged in the low-voltage chamber, the transformer comprises a primary end and a secondary end, the primary end is connected with the mains supply end, and the secondary end is connected with the user terminal. The mobile transformer substation further comprises a reactive phase angle detection module and a reactive compensation module. The reactive compensation module comprises a capacitor module and an adjustable inductor. The capacitor module and the adjustable inductor are respectively connected to the secondary end in parallel, the reactive phase angle detection module is installed on a main circuit of the secondary end, the reactive phase angle detection module detectsa main circuit power factor value and transmits a signal to the adjustable inductor, and the adjustable inductor adjusts the inductance value of the adjustable inductor to enable the main circuit power factor of the secondary end to tend to 1.

Description

technical field [0001] The invention relates to the field of power supply transmission, in particular to a mobile substation. Background technique [0002] The substation is a very important part of the power system. In the existing technology, most of the substations are box-type substations built with concrete, which takes a long construction period and is slow to put into use. [0003] In some occasions, such as regional construction sites far away from the urban area, large-scale activities with high load power consumption and the capacity of the local substation is not enough, or after a certain substation fails, it needs to be repaired but cannot be repaired in time and needs assistance The substation is used for temporary power transformation. In these occasions, a power transformation device that can be used to connect the mains and the user end is required. It must respond quickly and work in place, and the power transformation must be reliable and safe. Contents ...
