Description
Technical field
The utility model belongs to transformer device field, especially relates to a kind of instrument transformer with explosion prevention function.
Background technology
Instrument transformer is also called instrument transformer, is the general designation of current transformer and voltage transformer.High voltage can be become low-voltage, big current becomes small area analysis, for measuring or protection system; High voltage or big current scaling transformation are mainly become normal low voltage or standard small area analysis by its function; to realize the standardization of measuring instrument, proterctive equipment and automatic control equipment, miniaturization; instrument transformer also can be used to separate high-voltage system simultaneously, to ensure the safety of the person and equipment.But along with the raising of electric pressure, the insulation for the instrument transformer transformed is more and more difficult, and temperature also can raise relatively, especially existing oil-containing instrument transformer more has explosion hazard, existing instrument transformer existing defects in explosion protection.
Utility model content
In view of this, the utility model is intended to the instrument transformer proposing to have explosion prevention function, can the temperature on monitoring device surface, and heat insulation and perfect heat-dissipating, has protection and reduce explosion hazard function.
For achieving the above object, the technical solution of the utility model is achieved in that
A kind of instrument transformer with explosion prevention function, comprise shell and be arranged on the closed iron core in described shell, former limit winding and vice-side winding, primary side end with described former limit winding switching is provided with above described shell, the bottom of described shell is provided with secondary terminal connections seat, described secondary terminal connections seat is provided with the secondary terminal be connected with described vice-side winding, the left and right side of described shell is also provided with the explosion-proof tank of boss shape evagination, anti-explosion partition is provided with between described explosion-proof tank and described shell, explosion-proof filler is filled with in described explosion-proof tank, the outer surface of described explosion-proof tank is provided with many places temperature sensor, described temperature sensor is connected with the control unit be positioned on described shell, described control unit is also connected with wireless transmission unit.
Further, described anti-explosion partition is the Al-alloy metal plate that surface has micropore, the surface of described Al-alloy metal plate is inlaid with the cancellated metallic radiating layer of honeycomb.
Further, described explosion-proof filler comprises quartz sand and filament mixes the cotton-shaped filler be entwined.
Further, described control unit is single-chip microcomputer.
Relative to prior art, the instrument transformer with explosion prevention function described in the utility model has following advantage:
The central space of shell and explosion-proof tank can be carried out explosiveproof isolation by anti-explosion partition of the present utility model, contribute to the closed iron core in shell, former limit winding and vice-side winding are closed in insulating space separately, and anti-explosion partition is the Al-alloy metal plate that surface has micropore, and be inlaid with the cancellated metallic radiating layer of honeycomb on the surface, the basis with the metal strength of division board also has good heat-sinking capability, contribute to the heat produced in the middle part of timely conductive can, explosion-proof filler is filled with in explosion-proof tank, can disperse in time in the middle part of shell through the heat that anti-explosion partition transmits, even if blast, explosion-proof filler also can moment closed interior demolition point, demolition point and air are separated as far as possible, weaken the power of blast, the many places temperature sensor that the outer surface of explosion-proof tank is provided with, can the variations in temperature of Real-Time Monitoring explosion-proof tank outer surface, and temperature parameter is delivered on control unit, temperature parameter is delivered on corresponding server by wireless transmission unit by control unit again, temperature conditions is checked by staff, reason can be investigated in time once note abnormalities, solve a problem promptly.
