Abstract
The invention discloses a fire extinguishing transformer. The fire extinguishing transformer comprises a coil rack for winding a coil, a magnetic core arranged in the central through hole of the coil rack, and also a fire-resistant transformer housing, a receiving chamber arranged on the fire-resistant transformer housing and used for receiving a fire extinguishing component, a thermal expansion component arranged on the receiving chamber, a sheet arranged on the receiving chamber, ventilation openings formed at the two sides of the fire-resistant transformer housing, rotatable sealing components arranged beside the ventilation openings and used for sealing the ventilation openings, and a temperature sensor arranged in the fire-resistant transformer housing. The fire extinguishing transformer is characterized in that in case of a fire, the thermal expansion components expands so that the sheet is squeezed and broken by a dry powder extinguishing agent, and when the ambient pressure is lower than the pressure in the receiving chamber, the dry powder extinguishing agent erupts to extinguish fire; the fire extinguishing transformer is good in effect and low in cost.
Description
Technical field
An electric equipment, particularly a kind of transformer.
Background technology
According to the transformer of prior art, mainly there is such form: primary coil and secondary coil are sequentially wrapped on single coil frame, and core is attached to bobbin by the through hole of bobbin.For fear of electric leakage or other accidents; conventionally can between magnetic core and bobbin, insulation cushion be set; but magnetic core can generate heat at work; impel the aging of insulation cushion, coil also can generate heat, heat accumulation; impel coil aging; thereby cause Local Fire, security incident occurs, prior art is unresolved such problem also.
Summary of the invention
For solving the deficiencies in the prior art, while the object of the present invention is to provide a kind of breaking out of fire, the thermal expansion of thermal expansion part, powder extinguishing agent sheet extrusion, thin slice is racked, and ambient pressure is less than the air pressure in accommodating chamber, powder extinguishing agent ejection, fire is eliminated, and effective, cost is low.
In order to realize above-mentioned target, the present invention adopts following technical scheme:
A kind of fire extinguishing transformer, comprise: the bobbin of winding around, be placed in the magnetic core in bobbin central through hole, also comprise: fire-resistant transformer case, be located on fire-resistant transformer case and for holding the accommodating chamber of extinguishing member, be located at the thermal expansion part on accommodating chamber, be located at the thin slice on accommodating chamber, be located at the ventilating opening of fire-resistant transformer case both sides, be located at the closed component of the other rotatable and enclosed ventilation mouth of ventilating opening, be located at the temperature inductor in fire-resistant transformer case.
Aforesaid a kind of fire extinguishing transformer, extinguishing member is powder extinguishing agent.
Aforesaid a kind of fire extinguishing transformer, thermal expansion part is silicon rubber.
Aforesaid a kind of fire extinguishing transformer, thin slice is tinfoil sheet.
Aforesaid a kind of fire extinguishing transformer, the material that fire-resistant transformer case adopts is thermosetting resin-impregnated paper high-pressure laminated board.
Aforesaid a kind of fire extinguishing transformer, ventilating opening place is provided with anti-hawk.
Aforesaid a kind of fire extinguishing transformer, anti-hawk is web plate.
Usefulness of the present invention is: while the invention provides a kind of breaking out of fire, and the thermal expansion of thermal expansion part, powder extinguishing agent sheet extrusion, racks thin slice, and ambient pressure is less than the air pressure in accommodating chamber, and powder extinguishing agent ejection, eliminates fire, and effective, cost is low.
Accompanying drawing explanation
Fig. 1 is a kind of sectional view of a kind of embodiment of the present invention;
The implication of Reference numeral in figure:
1 bobbin, 2 fire-resistant transformer cases, 3 ventilating openings, 4 thin slices, 5 accommodating chambers, 6 anti-hawks, 7 powder extinguishing agents, 8 thermal expansion parts.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is done to concrete introduction.
A kind of fire extinguishing transformer, comprise: the bobbin 1 of winding around, be placed in the magnetic core in bobbin 1 central through hole, also comprise: fire-resistant transformer case 2, be located on fire-resistant transformer case 2 and for holding the accommodating chamber 5 of extinguishing member, be located at the thermal expansion part 8 on accommodating chamber 5, be located at the thin slice 4 on accommodating chamber 5, be located at the ventilating opening 3 of fire-resistant transformer case 2 both sides, be located at the closed component of the other rotatable and enclosed ventilation mouth 3 of ventilating opening 3, be located at the temperature inductor in fire-resistant transformer case 2; As a kind of preferred, extinguishing member is powder extinguishing agent 7; Thermal expansion part 8 is silicon rubber, and the coefficient of expansion of silicon rubber when 150-160 spends is 3%; Thin slice 4 is tinfoil sheet.
For fear of too high temperature, the shell of fire extinguishing transformer is burnt, ingress of air again, the material that fire-resistant transformer case 2 adopts is thermosetting resin-impregnated paper high-pressure laminated board.In order not allow extraneous dust enter in transformer, cause coil premature aging, ventilating opening 3 places are provided with anti-hawk 6; Anti-hawk 6 is web plate.
8 thermal expansions of thermal expansion part, powder extinguishing agent 7 sheet extrusions 4, rack thin slice 4, and ambient pressure is less than the air pressure in accommodating chamber 5, and powder extinguishing agent 7 ejections, eliminate fire, and effective, cost is low.
More than show and described basic principle of the present invention, principal character and advantage.The technical staff of the industry should understand, and above-described embodiment does not limit the present invention in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection scope of the present invention.
