Abstract
The utility model relates to a fire protection transformer which comprises a shell and a magnetic core arranged in the shell. A coil is wound on the magnetic core, the inner surface and the outer surface of the magnetic core are evenly coated with first fire protection layers, the inner surface of the shell is provided with a second fire protection layer, an air hole is formed in the lateral wall of the shell, and a net-shaped filtering device is arranged in the air hole. According to the fire protection transformer, the fire protection layers are arranged, the phenomenon that a fire breaks out due to the fact that a coil is in short is effectively prevented, potential safety hazards are greatly reduced, and meanwhile the radiating effect is good.
Description
Technical field
The utility model relates to a kind of fire prevention transformer.
Background technology
Transformer is to utilize the principle of electromagnetic induction to change the device of alternating voltage, and main member is primary coil, secondary coil and iron core (magnetic core).In electric equipment and radio-circuit, transformer is commonly used for lifting voltage, matched impedance, safety isolation etc.In generator, no matter be that coil movement is passed through magnetic field or Movement in Magnetic Field by fixed coil, all can be in coil induced potential.
Power transformer is the most expensive and most important equipment of power plant and transformer station, the flood control poor performance of transformer of the prior art, particularly, when coil is worked for a long time under high load capacity electric current, easily makes winding wire short circuit, fire accident, causes the very big loss of property.
Utility model content
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of fire prevention transformer is provided.
The utility model is to be achieved through the following technical solutions:
A fire prevention transformer, comprises that housing, described housing are built-in with magnetic core, on described magnetic core, is wound with coil, and the inner surface of described magnetic core and outer surface are evenly coated with the first fireprotection layer, and the inner surface of described housing is provided with the second fireprotection layer.
Further, the sidewall of described housing is provided with ventilation hole.
Further, described ventilation hole is built-in with netted filtering device.
Further, described the first fireprotection layer and the second fireprotection layer adopt same material.
Further, described the first fireprotection layer is identical with the thickness of the second fireprotection layer.
Compared with prior art, the beneficial effects of the utility model are: the utility model, by fireprotection layer is set, has prevented the phenomenon that coil short is on fire effectively, thereby have greatly lowered potential safety hazard, simultaneously good heat dissipation effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
Described a kind of fire prevention transformer, comprise that housing 1, described housing 1 are built-in with magnetic core 2, on described magnetic core 2, be wound with coil 3, the inner surface of described magnetic core 2 and outer surface are evenly coated with the first fireprotection layer 4, the inner surface of described housing 1 is provided with the second fireprotection layer 5, and described the first fireprotection layer 4 and the second fireprotection layer 5 adopt same material, and their thickness is identical, effectively prevent the phenomenon that coil short is on fire, thereby greatly lowered potential safety hazard.
The sidewall of described housing 1 is provided with ventilation hole 6, improves its radiating effect; Described ventilation hole 6 is built-in with netted filtering device 7, prevents that airborne impurity from entering into transformer, the parts in stained transformer.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.
