Description
Technical field:
The utility model relates to transformer technology field, is specifically related to a kind of transformer ventilation and protection device.
Background technology:
Transformer (Transformer) utilizes 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).Major function has: voltage transformation, current transformation, impedance transformation, isolation, voltage stabilizing (magnetic saturation transformer) etc.Can be divided into by purposes: distribution transformer, power transformer, full-sealed transformer, combined transformer, dry-type transformer, oil-filled transformer, single-phase transformer, furnace transformer, rectifier transformer etc.The ventilation of existing transformer relatively simple for structure, and there is no device that is moistureproof and protection, through the interior contact of the aperture on aeration structure to transformer time child may be at play, cause security threat, and on rainy day or very in malaria, water droplet and denseer steam by the aperture of the structure of ventilation to the internal penetration of transformer, can cause security threat equally.
Utility model content:
It is good that technical problem to be solved in the utility model is to provide a kind of barrier propterty, the transformer ventilation and protection device that fail safe is high.
Technical problem to be solved in the utility model adopts following technical scheme to realize:
A kind of transformer ventilation and protection device, it is characterized in that: comprise casing, ventilating board, baffle and the anti-guncotton of moisture absorption, the rear side of described casing is provided with ventilating window, described ventilating board covers the outside of ventilating window, the plate face of ventilating board is provided with ventilation hole, described baffle is arranged on the inside of casing and correspond to the position of ventilating window, baffle is evenly provided with air-vent, the top of baffle is connected with the top of box house, the bottom that lower end and the box house of baffle are provided with ventilating window is connected, external series gap is provided with between baffle and ventilating board, the anti-guncotton of described moisture absorption is arranged in external series gap.
The outer upper that described ventilation hole is is provided with shield.
The arranged outside that the inner side of described baffle is positioned at air-vent has U-shaped baffle plate.
The top that the top of described casing is positioned at external series gap is provided with material hole, and described material hole is coated with cover plate.Be convenient to the anti-guncotton of moisture absorption in replacing or airing external series gap.
The utility model is that the inner side at ventilating window is provided with baffle; even if child through outside inside from ventilating board to casing touch also can not directly touch electricity device; and steam also with the globule cannot penetrate into the inside of casing from ventilating window and contact with there being the device of electricity; moisture absorption anti-guncotton ability also has good permeability, can not badly influence the effect of ventilating window.
The beneficial effects of the utility model are: the utility model structure is simple, easy to use, moistureproof, rainproof effect is good, and can protect the touch of child, barrier propterty is good, and fail safe is high.
Accompanying drawing illustrates:
Fig. 1 is the utility model structural representation.
Embodiment:
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As shown in Figure 1, a kind of transformer ventilation and protection device, comprise casing 1, ventilating board 2, baffle 3 and the anti-guncotton 4 of moisture absorption, the rear side of casing 1 is provided with ventilating window 5, ventilating board 2 covers the outside of ventilating window 5, the plate face of ventilating board 2 is provided with ventilation hole 6, baffle 3 is arranged on the inside of casing 1 and correspond to the position of ventilating window 5, baffle 3 is evenly provided with air-vent 7, the top of baffle 3 is connected with the top of casing 1 inside, the bottom that lower end and casing 1 inside of baffle 3 are provided with ventilating window 5 is connected, external series gap 8 is provided with between baffle 3 and ventilating board 2, the anti-guncotton 4 of moisture absorption is arranged in external series gap 8.The outer upper that ventilation hole 6 is is provided with shield 9.The arranged outside that the inner side of baffle 3 is positioned at air-vent 7 has U-shaped baffle plate 10.The top that the top of casing 1 is positioned at external series gap 8 is provided with material hole 11, and hole 11 is coated with cover plate 12 to material.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
