Abstract
Disclosed is a high-voltage prevention encapsulated transformer. According to the high-voltage prevention encapsulated transformer, a round piezoresistor with the diameter being 5 millimeters is connected in parallel at the two ends of a transformer primary coil used for producing the encapsulated transformer, in the working process of the encapsulated transformer, when high-voltage surges, pulses and inductive thunder which exceed the break-over voltage of the piezoresistor are encountered, the high-voltage surges, pulses and inductive thunder can be absorbed by the piezoresistor, and thus the primary coil of the encapsulated transformer is protected.
Description
Technical field
The present invention is the anti-high voltage surge of a kind of energy, pulse, can resist the potted transformer of induced lightening.
Background technology
Now all potted transformer all do not have the anti-high voltage surge of built-in primary coil, pulse, the protective device of anti-induction thunder, are inadequate like this.Potted transformer is to miniaturization, the wire diameter of primary coil is more and more less, more and more fragile, the wire diameter of the primary coil enamelled wire of the small-sized potted transformer had only has 0.03 millimeter, the thickness of its insulation coat of paint only has 0.001 millimeter, slight scratch is that difficulty is avoided in process of production, if there is slight scratch, the equipment of factory not easily detects, if such potted transformer is used in bad environments, voltage is higher, high voltage surge, pulse is many, the place that thunderbolt is many, potted transformer is elementary directly in parallel with 220 volts of alternating currents, large by ectocine, just be easy to cause because insulation degree is inadequate, between primary turns, easily spark is produced between coil and silicon steel sheet, casting glue heating bulge or primary coil are burnt out.
Summary of the invention
In order to prevent high voltage surge, pulse and induced lightening to the damage of potted transformer primary coil, the invention provides a kind of anti-high pressure potted transformer, in case high voltage surge, pulse, anti-induced lightening.
The technical solution adopted for the present invention to solve the technical problems is: at the pin at the transformer two ends for the production of potted transformer, parallel and connect the circular piezo-resistance of an admittance voltage 470 volts of diameters 5 millimeters, this piezo-resistance is loaded shell together with transformer, pours into polyurethane pouring sealant and dry, make anti-high pressure potted transformer.Diameter 5 mm of thickness about 2 millimeter of this circular piezo-resistance, volume is little, and when pouring into polyurethane casting glue, it floods by polyurethane pouring sealant, and outward appearance is substantially unaffected.Just absorbed by piezo-resistance when running into high voltage surge, pulse higher than 470 volts; when run into stronger induced lightening then piezo-resistance conducting absorb energy together with the fuse in 220 volts of alternating current circuits, air switch; thus protect fragile primary coil, protect potted transformer.
The invention has the beneficial effects as follows: the potted transformer primary coil making fragile potted transformer primary coil and even have the shop equipment of slight scratch not easily to detect, be effectively protected higher than when 470 pressure surges, pulse, induced lightening running into.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further described.
Fig. 1 is circuit theory diagrams of the present invention.
Fig. 2 is the sectional structure chart of anti-high pressure potted transformer.
1. conducting voltage, 470 volts of diameters, 5 millimeters of circular piezo-resistances in figure, 2. transformer is elementary, 3. transformer secondary output, 4. silicon steel sheet, 5. coil pin, 6. shell.
Specific embodiments:
In Fig. 1,2, at a pin for the production of the EI type transformer two ends of potted transformer, parallel and connect the circular piezo-resistance an of conducting voltage 470 volts of diameters 5 millimeters, this piezo-resistance is loaded in shell together with EI transformer, pour into polyurethane pouring sealant, and this piezo-resistance is flooded, make outward appearance unaffected, dry and make anti-high pressure potted transformer.
Claims (1)
1. an anti-high pressure potted transformer, it is characterized in that: parallel for the production of the transformer two ends of potted transformer and connect the circular piezo-resistance an of conducting voltage 470 volts of diameters 5 millimeters, this piezo-resistance is loaded shell together with transformer, dry after filling polyurethane pouring sealant, make anti-high pressure potted transformer.
