Panels of switchboards SCHO-06 are designed to receive and distribute electrical energy of three-phase alternating current with a frequency of 50 Hz and voltage up to 660 V and to protect outgoing lines from overloads and short-circuit currents. Type of climatic modification U3 in accordance with GOST 15150. Normal operation of SCHO is provided under the following conditions: 1. Height above sea level - no more than 1000 m; 2. Environment - non-explosive, not containing conductive dust, corrosive gases and vapors in concentrations that reduce the parameters of the KTP within unacceptable limits; 3. Wind speed up to 36 m / s (wind pressure speed up to 800 Pa); 4. Type of atmosphere - II in accordance with GOST 15150. SCHO panels are manufactured in two versions according to the degree of protection (the first digit in the panel designation): 1 - open (degree of protection IP00 and only from the side of the facade - IP20); 2 - closed (degree of protection IP20 and only from the bottom side - IP00). According to the purpose, the panels are divided into introductory, sectional, distribution and auxiliary ones. Accessory panels include supervisory panels, metering cabinets, and end panels. When installing the panels in two rows, the switchgear is equipped with a busbar bridge with a distance between the facades of -1000, 1500 and 2000mm. The panels are equipped with the following equipment: 1. Introductory and sectional - automatic switches of withdrawable and fixed design and circuit breakers, 2. Distribution circuit breakers - withdrawable or fixed circuit breakers, RPS fuse switches or insulated switches with RBK or ARS fuses. On request, the products are completed with installations for reactive power compensation. Panels are assembled into transport groups up to 4 m long.
