A kind of firewall transformer oil anti-splash device, the device by firewall, be fixed on the antispray of firewall facade Every and the antispray paulin that is arranged at the top of firewall totally 3 big components are constituted；Wherein: be fixed on antispray on firewall facade every By it is horizontally-supported and be fixed on it is horizontally-supported between antispray partition form, antispray every each end be both provided with and prevent The antispray of transformer oil splash diffusion is every turnover；Antispray paulin at the top of firewall then by short cantilever beam and is fixed between short cantilever beam Antispray paulin plate, antispray paulin plate end antispray paulin transfer composition；Short cantilever beam and horizontally-supported it is each attached to firewall On；

Utility model device relies on transformer or the setting of reactor firewall；When there are transformation in the adjacent two sides of firewall When device or reactor, firewall transformer oil anti-splash device needs to be symmetrical arranged in firewall two sides；When firewall side Have transformer perhaps reactor when only need to transformer or reactor side setting firewall transformer oil anti-splash device； Utility model device antispray is directed on the inside of firewall every the bending or turnover done with antispray paulin, limits splash Transformer oil do not diffuse into adjacent transformers or reactor；

When the utility model transformer or reactor use top surface cannula structure, firewall height becomes compared with side casing Depressor or reactor firewall height are high；Firewall uses armored concrete or the structures such as brick or steel；Anti-splash device can be with Using the light material with fire-proof function；When transformer or the not set special explosion-protection equipment of reactor, firewall and Firewall transformer oil anti-splash device should use blast resistance construction.

The setting of the utility model anti-splash device must not influence transformer equipment operation and maintenance.

The utility model and existing Explosion of Transformer fire protection wall difference:

(1) protective range is different, and the utility model anti-splash device is positioned only at transformer and reactor two sides,

Only play the transformer oil antispray between adjacent transformers or reactor；Pervious protecting wall is arranged in transformation Device or reactor surrounding play explosion-proof, fire prevention, antispray, oil-blocking action between transformer bay and transformer and electrical equipment；

(2) influence implemented is different: the utility model anti-splash device is directly installed at transformer or reactor fire prevention It is easy to implement on wall；Protecting wall setting affects ventilation, the unmanned robot operation and maintenance of transformer of transformer etc., needs Separately to consider the equipment such as ventilation；

(3) it is structurally also slightly different, anti-splash device height considers according to concordant with Auxiliary Transformer Firewall height, fire prevention Wall is higher than firewall.

The beneficial effects of the utility model are embodied in: the present apparatus is that the serious explosive fire accident fire extinguishing of transformer is essential auxiliary Help fire fighting device, can limiting transformer oil splash fire range to greatest extent, prevent adjacent transformers or reactor from sending out Raw working fire continues re-ignition fire, reduces fire damage, providing most for the performance fire extinguishing effect of transformer fixed fire extinguishing system Basic guarantee.
