KTPK

Kiosk-type KTP are 1 or 2 transformer substations with outdoor installation type. They are used to receive, transform and transit electric power. They are installed on a prepared special site. There are dead-end and pass-through ones. They are divided into KTP of overhead and cable input on the HV or LV side. Complete transformer substation of pass-through or dead-end type of outdoor installation with one transformer KTPK is designed to receive electric energy of three-phase alternating current with a frequency of 50 Hz, rated voltage of 6 (10) kV, convert it to voltage of 0.4 kV and distribute to consumers. Structurally, KTPK consists of the following compartments: - compartment of the device on the high-voltage side - UVN; - power transformer compartment; - compartment of the switchgear on the low-voltage side RUNN. The device on the high-voltage side is implemented on load switches VNA-10/630-20. Electric power supply to the UVN compartment is cable or overhead. Oil transformers TM, TMG with a capacity of up to 630 kVA can be installed in the power transformer compartment. The doors of the transformer compartments have louvers for natural ventilation. The switchgear on the low-voltage side can be made on a wall panel or on ЩО 70-3 panels, the type and quantity of which are determined when ordering. The input of outgoing cables into the RUNN compartment is provided from below through a cable pit or from above through an air outlet. The KTPK shell is an all-metal welded structure. The KTPK body has places for connecting external grounding conductors, designated by grounding signs in accordance with GOST 21130-75.
