Detailed Product Description
ZE4123 Demonstration Panel for
the Electric
Testing Carried Out in A Building Teaching Equipment 1.INTRODUCTION This panel can be used by teachers for their lessons and by students for an easy learning and testing on electrical prevention systems supplying them with the means for verifying the rule of art and the relevant technical standards. Actual electrical devices installed, already connected with each other, enable to check the operation, besides carrying out the measurements of all the electric parameters with conventional instruments. The panel is made of insulating material and it represents the support of the necessary devices for carrying out the testing programme. The apparatuses are represented on the panel with their standardized international symbols and electrical block diagram, for an easy reference with their lay-out. Furthermore, when necessary, test points correspond to standardized educational terminals with high protection degree against accidental contacts. 2.TRAINING PROGRAM: This panel can be used to defi ne the electrical installations of a building (power distribution via TT system) with reference to the following topics: Electrical installation of the building complying with guide Graphic symbols for installation plans Branch exchange for a fl at Meter room and riser Earthing system for the block of fl ats Furthermore, this panel is designed to deal with topics, visual checks, tests concerning: Protection systems against direct and indirect contacts Choice of conductors, current-carrying capacity and voltage drop Testing the paths of conductors and their suitability and duct diameter and removableness of conductors Suitability of materials and of equipment Protection and breaking devices Identifi cation of neutral and earth conductors Suitability of the connections of conductors Continuity of protection and equipotential conductors Isolation resistance 3.TECHNICALSPECIFICATIONS: Framework is made of sheet steel chemically treated and painted with several coats of epoxy varnish; its base is provided with rubber feet and it can be positioned on a working top. All the necessary electric components for the correct power supply of circuits are included in the panel. Main components installed: 1 single-phase isolation transformer 230 V / 230 V 230 VA 2 simulators of earth plate with resistors of 2 Ω, 20Ω, 200 Ω, 2 kΩ 1 simulators of resistance of protection conductor with resistors of 0.1 Ω, 1 Ω 1 simulator of extraneous conducting part with resistances of 200 Ω, 1000 Ω, 5000 Ω 1 magnetothermal circuit breaker 2 x 2 A “C” 1 magnetothermal circuit breaker 2 x 1 A “C” 1 differential circuit breaker 2 x 1.6 A “C” / 30 mA “AC” 1 magnetothermal and differential circuit breaker 2x25 A/30 mA “A” 1 protection and control switch – 2P +Earth Two 2-pin sockets – 10/16 A, 2P + Earth 2 simulators of isolation earth fault in power consuming Device with resistors of 50 kΩ, 15 kΩ, 5 kΩ, 1500 Ω, 500 Ω, and bolted fault Dimensions of demonstration panel: 800 x 600 mm Dimensions of framework: 840 x 450 x 680 mm Net weight: 33 kg SUPPLIED ACCESSORIES: 1 single-phase power cord with UNEL plug 8 jumpers with safety plugs (Ø 4 mm) for assembling the various installation conditions 4.RECOMMENDED ACCESSORIES AND SOFTWARE: Multi-function microprocessor instrument for electric testing Digital current probe Digital autoranging multimeter Circuit design, simulation and animation software for electrical engineering projects POWER SUPPLY: 230 V / PE 50-60 Hz; Max. absorption: 250 VA |
