Abstract

The utility model discloses an extinguishment transformer which comprises a coil frame wound with a coil, a magnetic core arranged in a center through hole of the coil frame, a fire-resistant transformer outer shell, ventilation openings formed in the two sides of the fire-resistant transformer outer shell, rotatable sealing components which are arranged beside the ventilation openings and seal the ventilation openings, a temperature sensor arranged in the fire-resistant transformer outer shell and an air exhaust piece arranged on the fire-resistant transformer outer shell. When the coil or the magnetic core are too hot, so that the coil burns to cause a fire disaster, the transformer can be sensed and sealed automatically, oxygen in the transformer is taken out, accordingly, the effect of extinguishment is achieved, effect is good, and cost is low.

Description

Fire extinguishing transformer

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.

Utility model content

For solving the deficiencies in the prior art, the purpose of this utility model be to provide a kind of when coil or magnetic core overheated, while causing coil burning to cause fire, can sense and automatically transformer is closed, and the oxygen in transformer is taken away, thereby reach the effect of fire extinguishing.

In order to realize above-mentioned target, the utility model adopts following technical scheme:

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 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, be placed in the part of bleeding on fire-resistant transformer case.

Aforesaid fire extinguishing transformer, closed component forms to be had: be fixed on the rotating part on fire-resistant transformer case, be connected in the closing cap of rotating part, cover on closing cap and contact the sealant of ventilating opening.

Aforesaid fire extinguishing transformer, rotating part is electric rotation shaft.

Aforesaid fire extinguishing transformer, sealant is rubber layer.

Aforesaid fire extinguishing transformer, the material that fire-resistant transformer case adopts is thermosetting resin-impregnated paper high-pressure laminated board.

Aforesaid fire extinguishing transformer, ventilating opening place is provided with anti-hawk.

Aforesaid fire extinguishing transformer, anti-hawk is web plate.

Aforesaid fire extinguishing transformer, the part of bleeding is the electronic air extracting pump being communicated in fire extinguishing transformer.

Usefulness of the present utility model is: the utility model provide a kind of when coil or magnetic core overheated, while causing coil burning to cause fire, can sense and automatically transformer is closed, and the oxygen in transformer is taken away, thereby reach the effect of fire extinguishing, effective, cost is low.

Accompanying drawing explanation

Fig. 1 is the sectional view of a kind of embodiment of the present utility model;

The implication of Reference numeral in figure:

1 bobbin, 2 fire-resistant transformer cases, 3 ventilating openings, 4 temperature inductors, 5 electronic air extracting pumps, 6 rotating parts, 7 closing caps, 8 sealants, 9 anti-hawks.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is done to concrete introduction.

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 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 4 in fire-resistant transformer case 2, be placed in the part of bleeding on fire-resistant transformer case 2; As a kind of preferred, the part of bleeding is the electronic air extracting pump 5 being communicated in fire extinguishing transformer.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.

Closed component forms to be had: be fixed on the rotating part 6 on fire-resistant transformer case 2, be connected in the closing cap 7 of rotating part 6, cover on closing cap 7 and contact the sealant 8 of ventilating opening 3; As a kind of preferred, rotating part 6 is electric rotation shaft; Sealant 8 is rubber layer, so long as the rotating part 6 that closing cap 7 can be rotated is all applicable to the utility model, and can be as sealant 8 so long as can play the material of sealing function.

In order not allow extraneous dust enter in transformer, cause coil premature aging, ventilating opening 3 places are provided with anti-hawk 9; Anti-hawk 9 is web plate.

When temperature inductor 4 senses temperature higher than set point, by communication to controller, so long as Programmable Logic Controller is all applicable to the utility model, controller is controlled motor and is driven electric rotation shaft to rotate, and ventilating opening 3 is closed, sealant 8 guarantees to seal ventilating opening 3, this Time Controller is controlled motor and is driven electronic air extracting pump 5 operations that the air in transformer is extracted out, and oxygen is disappeared sooner, there is no oxygen, fire also cannot continue, thereby reaches the object of fire extinguishing.

The utility model provide a kind of when coil or magnetic core overheated, while causing coil burning to cause fire, can sense and automatically transformer is closed, and the oxygen in transformer is taken away, thereby reach the effect of fire extinguishing, effective, cost is low.

More than show and described basic principle of the present utility model, principal character and advantage.The technical staff of the industry should understand, and above-described embodiment does not limit the utility model in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection range of the present utility model.
