Embodiment Construction
[0027] Attached below Figure 1~8 And specific embodiment, the present invention is described in detail.
[0028] refer to Figure 1~8 , used for the moisture-proof and foreign-body-proof device of the oil discharge nitrogen injection fire extinguishing system, including the anti-fog film cover foreign object detection unit and the linkage alarm unit 4; the anti-fog film cover foreign object detection unit includes the anti-fog film cover 1, bracket 2 and foreign object detection equipment 3. The anti-fog film cover 1 is flat-bottomed bowl-shaped, and the middle part of the anti-fog film cover 1 is provided with a cross pre-opening valve 1-1. The edge of the cross pre-opening valve 1-1 is thick and the middle is thin, which can prevent foreign matter from entering; The bracket 2 is a flat bracket, and the foreign object detection device 3 is installed in the middle of the bracket 2; the foreign object detection device 3 is connected to the linkage alarm unit 4 through a wire,...

The invention discloses a moisture-proof and foreign-matter-proof device for an oil-discharging nitrogen-injecting fire extinguishing system, belongs to the technical field of transformer fire fighting, and relates to the oil-discharging nitrogen-injecting fire extinguishing system. The moisture-proof and foreign-matter-proof device has the functions of fog prevention, foreign matter entering prevention and alarming. The moisture-proof and foreign-matter-proof device comprises an anti-fog film sleeve foreign matter detecting unit and a linkage alarming unit, wherein the anti-fog film sleeve foreign matter detecting unit comprises an anti-fog film sleeve, a support and a foreign matter detecting device; the anti-fog film sleeve is in a flat-bottom bowl shape; a cross-shaped pre-opening valve is arranged in the middle of the anti-fog film sleeve, is thick in edge and thin in middle and is used for preventing foreign matter from entering; the support is a flat-plate-shaped support; the foreign matter detecting device is installed in the middle of the support and connected with the linkage alarming unit through a wire; and the linkage alarming unit receives a signal of the foreign matter detecting device and sends out a sound-light alarming signal. The moisture-proof and foreign-matter-proof device is reasonable in structure, can be conveniently additionally installed on an existing oil-discharging nitrogen-injecting fire extinguishing device, and does not need to be greatly changed. The function expansibility is high, and alarming information can be effectively processed in time.
Description
technical field [0001] The invention relates to a moisture-proof and foreign matter-proof device for an oil discharge and nitrogen injection fire extinguishing system, which belongs to the technical field of transformer fire protection, and relates to a device for an oil discharge and nitrogen injection fire extinguishing system, which has the functions of preventing fog and foreign matter from entering and having an alarm function. Background technique [0002] When a fault occurs inside the transformer, a large amount of flammable gas is generated inside the oil tank, causing the gas relay to operate, sending a heavy gas signal, and the circuit breaker trips; the internal fault of the transformer also causes the oil temperature to rise, and the temperature-sensitive fire detector arranged on the transformer operates to The fire control cabinet sends out a fire alarm signal. After receiving the fire alarm signal, heavy gas signal, and circuit breaker trip signal, the fire c...
