Our Product / Services
We offer the best product range of Dissectible Transformer, Demonstration Transformer, Demountable Transformer and Auto Transformer.
This apparatus has been designed primarily for demonstration of the basic principles of the a.c. transformer. The various coils and cores will also serve as the basis of many experiments in electromagnetism, using either direct or alternating current. To this end, the number of turns, the direction of winding and the continuous maximum rated current are marked on each coil.
Contents:-
1Clamp base.
1laminated U core length of side 133mm, base 95mm, section 32 x 25mm.
1 laminated armature 95 x 32 x 25mm.
2 soft iron pole pieces.
1 300-turn 4A coil.
2 600-turn 2A coils.
1 1200-turn 1A coil.
1 3600-turn 0.3A coil, centre tapped.
1 12000-turn 0.05A coil.
1 detailed instruction book.
In the basic transformer set all coils are fitted with 4mm socket connection, but 600-, and 1200-, turn coils are available (as accessories) fitted with shielded plugs for connection to the a.c. mains supply. All coils are of enamelled copper wire wound on high impact plastic moulded bobbins 75mm long with cheeks 75x60mm. The robust clamping base is provided with a tommy-bar screw to hold the U core, and two knurled nuts to secure the armature and provide for easy changeover of the coils. Soft iron pieces are provided which locate on top of the U core arms. One end of each pole piece is flat so that the pole pieces in situ provide a narrow gap with the full cross-sectional area, while the other end is in the form of a truncated cone giving a narrow concentrated field between the poles.
SKU: GP0673B
Comprises :
Laminated U and I cores of low-loss magnetic material, to form a closed core of cross-section 25mm in plane of laminations, 32mm perpendicular to them, I-core length 102mm, U-core external height 102mm, internal height to take bobbin length 77mm.
Pair of pole pieces, each 65x30x25mm, length x width x height with one end shapered to part of a cone for maximum flux density. Hole drilled through total length along cone exis to take a light beam. Pole pieces will accept support rods and shading ring of accessory set 2 and may be clamped at any separation on U-core, or in contact as a non laminated I-core.
Cast aluminium alloy stand consisting of a heavy base on four rubber feet with two removable clamping arms. Maximum dimensions of base 190x200x115mm, width x depth x height. Channel, 35mm wide, 3mm deep to take transformer core, extends across full width. Integral support for arms, to rear, is below the level of the pole-pieces. Arms pivot on steel spindle with adjustment of knobs to rear bringing hard rubberpads at a front end of arms to bear on transformer core. Synethetic hammer finish except of clean metal in channel and 4mm hole to take an earthling plug lead.
Coils for demountable transformer. Wound on rectangular insulating bobbins, overall height 71mm, maximum corss- section including extension to front panel 72x110mm, width x depth, internal cross-section 26.533.5, width x depth. Connection to tiop and of bobbin. Front panel clearly marked with number of turns. The 300 and 600 turns coils, intended
for low voltages, each have connection to pair of 4mm sockets at 19mm spacing. The 1200-, 3600- and 12000- turn coils may be used on a mains supply and are wired to plug half of three pin flex connector. Earth pin wired to front panel and green 4mm sockets. A separate mains connector, consisting of three pin socket and 1.8m three core flex, is supplied with each mains coil.
