Abstract
The utility model relates to a kind of full working scope type low-voltage current mutual inductor, comprise iron core-closed, secondary winding and housing, iron core-closedly be arranged at housing upper, secondary winding be wound in iron core-closed on, described housing bottom surface is provided with the secondary terminal box be inwardly recessed, secondary terminal box to be close to by screw dense block through base plate and sealing gasket and to be connected on housing bottom surface, and two output leads of secondary coil pick out through base plate through the water joint of sealing cross-under on base plate by secondary terminal box.Establish insulation burrel in instrument transformer pour mass is iron core-closed, the insulation distance of circuit through instrument transformer and instrument transformer secondary coil can be ensured, meet requirement of withstand voltage; Base plate, as the secondary connection lid plate of instrument transformer, adopts sealing gasket design, and output lead skin cover has net retardance, and pass base plate by water joint and can meet various particular surroundings, it is convenient to install, fixed.
Description
Technical field
The utility model relates to a kind of current transformer, is a kind of full working scope type low-voltage current mutual inductor specifically, measures and Microcomputer Protection for 0.66kV and following power circuit.
Background technology
In switch cubicle in the extensive use of existing punching low-voltage current mutual inductor and 0.66KV and following power circuit, the circuit through instrument transformer is measured and Microcomputer Protection.Along with electric power facility increase in investment in recent years, the construction of the engineerings such as transferring electricity from the west to the east, north and south supply mutually, trans-regional networking, driven the fast development of switch cubicle industry, the environment for use brought thus is also complicated especially, as high temperature, humidity, salt fog etc.The circuit of general switch cubicle producer adopts copper bar and cable, and cable itself has insulation function, mainly relies on instrument transformer self insulating barrier to insulate according to copper bar.Therefore select one can meet various particular surroundings, the good instrument transformer of self insulation property is most important.
Summary of the invention
In order to solve above-mentioned deficiency of the prior art, the utility model provides one can meet various particular surroundings, the full working scope type low-voltage current mutual inductor that self insulation property is good.
The technical solution of the utility model is: a kind of full working scope type low-voltage current mutual inductor, comprise iron core-closed, secondary winding and housing, iron core-closedly be arranged at housing upper, secondary winding be wound in iron core-closed on, described housing bottom surface is provided with the secondary terminal box be inwardly recessed, secondary terminal box to be close to by screw dense block through base plate and sealing gasket and to be connected on housing bottom surface, and two output leads of secondary coil pick out through base plate through the water joint of sealing cross-under on base plate by secondary terminal box.
Further, described output lead is socketed with net retardance.
Further, described iron core-closed inner ring is provided with insulation burrel.
Again further, described housing is ABS housing or polyurethane shells or unsaturated-resin housing.
Compared with prior art, the utility model has the advantages that: in instrument transformer pour mass is iron core-closed, establish insulation burrel, the insulation distance of circuit through instrument transformer and instrument transformer secondary coil can be ensured, meet requirement of withstand voltage; Base plate, as the secondary connection lid plate of instrument transformer, adopts sealing gasket design, and output lead skin cover has net retardance, and pass base plate by water joint and can meet various particular surroundings, it is convenient to install, fixed.
