Abstract
The utility model relates to a fire prevention formula transformer case, which comprises a housin, casing top be provided with porous barrier, laid the ventilated membrane above the porous barrier, the ventilated membrane be the low melting membrane, ventilated membrane the higher authority is provided with inorganic drier powder layer, the casing is inside to be provided with supplementary extinguishing device, and supplementary extinguishing device is provided with a plurality of nozzles including setting up the trachea in the transformer top on, and the trachea is connected with the nitrogen gas source, is provided with the solenoid valve on the trachea, and the solenoid valve is connected with the temperature -sensing ware, and the temperature -sensing ware sets up on the transformer. The utility model discloses a fire prevention formula transformer case can in time put out a fire at the transformer initial stage on fire effectively, prevents the emergence of fire incident.
Description
Technical field
The utility model provides a kind of fire-proof type transformer case, belongs to electrical equipment technical field.
Background technology
Present high-power transformer mostly is oil injection type, and insulating oil about 1t approximately used by the transformer as 1000kVA, when transformer oil quality deterioration or transformer watered and wetting time, all can cause transformer insulated puncturing, cause short circuit, produce electric arc.Under the high temperature action of electric arc, transformer oil can decomposition gasification and rapidly flash burn catch fire, finally cause fire, and transformer oil burn that the fire that causes is more difficult to be put out, on fire to when taking effective fire suppression measures from finding, fire has often caused larger damage.
Utility model content
For solving the problem, the utility model provides a kind of fire-proof type transformer case, and concrete scheme is:
A kind of fire-proof type transformer case, comprise housing, be provided with porous barrier, be equipped with ventilated membrane above porous barrier above described housing, ventilated membrane is low melting point film, is provided with inorganic drying agents powder layer above ventilated membrane; Enclosure interior is provided with auxiliary extinguishing device, and auxiliary extinguishing device comprises the tracheae be arranged on above transformer, tracheae is provided with multiple nozzle, tracheae is connected with source nitrogen, tracheae is provided with electromagnetically operated valve, and electromagnetically operated valve is connected with temperature inductor, and temperature inductor is arranged on the transformer.
Further, described source nitrogen is outside nitrogen pipeline or the nitrogen pot being arranged on enclosure interior.
Further, described inorganic drying agents powder layer is activated alumina powder layer.
Further, described porous barrier is detachable.
Further, described housing side has radiator window.
The beneficial effects of the utility model are: in this programme, the case top of transformer case is provided with inorganic drying agents powder layer, when transformer normally runs, play the effect of moisture absorption protection against the tide, when there is short-circuit fire in transformer, the ventilated membrane Yin Wendu of low melting point raises and melts, the inorganic drying agents powder layer of top is leaked down from the hole of porous barrier, can play the effect covering fire extinguishing to the transformer that below is on fire in time; The auxiliary extinguishing device that enclosure interior is arranged simultaneously can spray a large amount of nitrogen when temperature exceeds normal value, plays the effect of auxiliary fire extinguishing.This programme can be put out a fire timely and effectively at the fire for transformer initial stage, prevents the generation of fire incident.
