CAB-1 User Cabin Panel I Trainer Didactic Equipment Electrical Training Panel
Movable desk-type equipment with wide synoptic panel representing the parts of a medium voltage cabin. It uses professional components to reproduce the operating conditions and the rules for ensuring protection and safety in compliance 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 enablingstandard configurations and/or any other configuration forexperimental aims. The connections on the fore panel (in three-phase voltage of380-400 Vac) are carried out via terminals and leads/jumperswith safety 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: • Simulator of cabin earth resistance with value selectablebetween 0.3 and 1 Ω. • General device reproduced with a 3-pole contactor In = 25 A • Line breaker and earthing switch reproduced by a rotaryswitch 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 • 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 Power supply: 230 Vac 50 Hz single-phase - 50 VA(Other voltage and frequency on request) Dimensions of operational panels: 800 x 600 mm Dimensions of the framework: 880 x 450 x 680 mm Weight: 27 kg Supply with THEORETICAL – EXPERIMENTAL HANDBOOK
