Utility model content
The technical problems to be solved in the utility model is, provides a kind of volume little, saves space, and long service life, can realize high-acruracy survey and power supply is provided, and high-pressure side and low-pressure end are all with the outdoor voltage transformer of fuse protection.
The technical scheme adopting is:
High and low pressure side all, with an outdoor voltage transformer for fuse protection, comprises housing, primary winding, secondary coil, iron core, it is characterized in that:
Secondary coil is wound on unshakable in one's determination upper, and primary winding is wound on the skeleton around secondary coil, primary winding, secondary coil and the poured with epoxy resin structure in aggregates of using unshakable in one's determination, and epoxy resin poured body is housing, and housing overcoat has one deck silicon rubber.
On the outer wall of housing, cover has silicon rubber full skirt, has two outlet terminal A phases and an outlet terminal B phase on the upper surface of housing, the overall structure that outlet terminal A phase and outlet terminal B phase and housing are one-time cast-forming.A built-in fuse respectively in a terminal of A phase and B phase, the two ends lead-in wire of the primary winding respectively fuse mutually built-in with A phase, B is connected, and A phase, the mutually built-in fuse of B are connected with A phase, B phase connection terminal respectively.The outer wall bottom of housing is provided with secondary terminal box, is provided with secondary fuse and a plurality of secondary wiring terminals in secondary terminal box.Two end lead-in wires of secondary coil are connected with secondary wiring terminals with secondary fuse respectively.
On the outer wall of the A phase of housing, instrument transformer and a terminal of B phase, cover has silastic-layer.
Housing lower surface is fixed in the mounting seat of being made by channel-section steel.
The utility model has the advantages that:
1, adopt high permeability, anti-saturation magnetic core, thereby the high sensitivity of realization, high reliability makes its unlikely too early appearance saturated phenomenon under overcurrent situations, guarantee that device can action message;
2, the utility model once, secondary coil draws line end fuse protection has all been installed, thereby solved the instrument transformer and the switch that cause due to short trouble, burns problem.
3, insulation property: whole epoxy resin and the silicon rubber composite insulation of adopting of instrument transformer, there is good mechanical strength, can realize high electric strength, low office discharge level, long service life;
4, the original same parameter voltage transformer of volume ratio is little, saves space;
5, all material is H level heat proof material, meets the fire protection requirement of fire department.
