Detailed Description
The high-voltage preassembled box-type transformer substation shown in fig. 1-3 comprises a cabinet body 1, a transformer 2 and an input cable 3, wherein the transformer 2 is installed in the cabinet body 1, an external connection hole 11 is formed in the cabinet body 1, a connecting cable 4 is respectively connected to an interface of the transformer 2, and each connecting cable 4 penetrates out of the external connection hole 11 and is respectively connected with the input cable 3. Typically, the transformer 2 has three interfaces, i.e. three-phase interfaces, and therefore three connection cables 4 are used for outgoing lines. Corresponding connectors are arranged at two ends of the connecting cables 4, one end of each connecting cable 4 is connected to a corresponding three-phase interface of the transformer 2, and the other end of each connecting cable 4 penetrates through the external hole 11 of the cabinet body 1 and is respectively connected with the external input cable 3, so that firm connection and correct wiring are ensured. Sufficient space is provided in the cabinet 1 for cabling, each cable being able to withstand the expected current loads and having a certain safety distance from each other, preventing mutual interference between electrical equipment and potential risk of short circuits.
