Cabinet of voltage selection (hereinafter SHON (into Russian - ШОН ) ) intended for the selection of the voltage coupling capacitors on existing and planned transmission lines with a nominal voltage of 35 to 750 KV, AC frequency of 50 Hz and 60 Hz, and also for transmission of measurement information signals by an automatic reclosing device (ARD) and synchronization devices.
Overall dimensions
SHON connection to the capacitor connection does not lead to deterioration of high frequency communication equipment. Schematic diagram SHON contains two transformers TOН intended to supply a matching devices, the other for power control relay synchronism and voltage. Rated primary current TOН - 0.128 A in the secondary - 0.15 A and 0.075 A. SHON design ensures safe operation in accordance with ГОСТ 12.2.007.0-75. Operation SHON without grounding is prohibited. Grounding bolt is on the right wall of the housing. At the lockers selection voltage is set by the warranty period - 6 months from the date the unit into operation, but no more than 1.5 years from the date of shipment.

in parentheses - rated voltage capacitors, kV;
and a nominal capacitance, nF (µF).
