STA-1 Substation Panel Trainer Teaching Equipment Electrical Training Panel
Movable desk-type equipment with wide synoptic panel representing the parts of a medium voltage substation. It uses professional components to reproduce the operating conditions and the rules for ensuring protection and safety in compl. with the standards in force applicable to the system typology. TECHNICAL CHARACTERISTICS: This unit is made of chemically treated sheet steel, painted withseveral coats of epoxy paint. Its base is provided with rubberfeet so that it can be positioned on any working top. Synoptic panels are made of aluminium alloy and they havebeen silk-screen printed with the international symbols; theyshow the necessary devices and connections for enabling standard configurations and/or any other configuration forexperimental aims. The connections on the fore panel (in three-phase voltage of380-400 V) are carried out via terminals and leads/jumpers withsafety plugs Ø 4 mm. The connections on the rear panel (in extra low safety voltageof 24 Vdc) are carried out via terminals and leads with safetyplugs Ø 2 mm. Main components installed • 3 single-phase transformers with primary winding of 230-400 V / secondary winding of 230 V, power of 500 VA, forassembling the HV / MV source. • Automatic magneto-thermal 4-pole switch equipped withminimum voltage coil and emergency pushbutton, warninglight indicating energized line, protection fuses of emergencystop circuit and transformers. • Simulator of cabin earth resistance with value selectablebetween 0.3 and 1 Ω. • General device reproduced with a 3-pole contactor In = 25 A Earthing switch reproduced by a rotary switch In = 32 A • PLC-controlled logic of interlocks and LED synoptic panelthat displays the availability of medium voltage in variouspoints of the circuit, the state of general device, the state ofline breaker, the state of earthing switch • Pushbuttons for manual start/stop control of general device • Modular PLC with display, 12 inputs of 24 Vdc / 8 outputs of24 Vdc • Regulated power supply of 24 Vdc 1.2 A • 3 current step-down transformers 5 / 1 A • 6 voltage step-down transformers 500 / 100 V • Toroidal current transformer for detecting homopolar earthcurrent • SEPAM relay series 40 (model S41) provided with advanceddialogue interface with graphic LCD and keys for displayingmeasures and parametrizations • Extension module of 10 inputs / 4 outputs applied to relay Dimensions of operational panels: 800 x 600 mm Dimensions of the framework: 880 x 450 x 680 mm Weight: 42 kg Supply with THEORETICAL – EXPERIMENTAL HANDBOOK
