Abstract
The utility model discloses a fire extinguisher for an oil discharging and rabbling type transformer, comprising an oil tank, an oil discharging valve, etc. The utility model is characterized in that the top of the oil tank of the transformer is provided with a temperature probe, the bottom of the oil tank is provided at least one nitrogen spraying pipe which is communicated with a nitrogen cylinder, a pressure reducing valve, a nitrogen through pipe, a check valve and a nitrogen through valve system. An oil discharging pipe is connected with a pressure control device which can simultaneously start a nitrogen release valve and the pressure reducing valve, and the pressure control device can spray nitrogen into the oil tank via the nitrogen spraying pipe. The utility model has the advantages of simple structure, convenient installation, low cost, high fire extinguishing speed, short maintenance time, no pollution, small damage degree, etc.
Description
The utility model belongs to the fire-fighting fire extinguishing technical field, specifically a kind of extinguishing device of transformer.
As everyone knows, oil filled transformer constantly all has the danger of catching fire, this is because the transformer internal short-circuit in using produces arc light, overvoltage, overload, makes the oil temperature surpass that burning-point caused.If tank internal pressure surpasses permissible value, some weak elements on the fuel tank will destroy, and after air enters, can cause fire, thereby badly damaged equipment causes the heavy losses of human and material resources.The extinguishing device that is used at present on the transformer has water extinguisher and tooth for the alkane extinguishing device, and these two kinds of extinguishing devices have cost cost height, and complex structure, and the action control point is many, shortcomings such as poor practicability.
The purpose of this utility model provides a kind of oil extraction fast and fills nitrogen from the oil extraction stirring-type transformer extinguishing device that puts out.
The purpose of this utility model is to realize like this, it includes oil tank of transformer, oil conservator, the oil conservator shut off valve, oil exit pipe, draining valve, it is characterized in that being provided with hygrosensor at the top of oil tank of transformer, draining valve is controlled by an electromagnetic mechanism that is connected with the hygrosensor signal sending element, at least be provided with one and nitrogen cylinder in the bottom of fuel tank, pressure-reducing valve, logical nitrogen pipe, check-valves, the nitrogens spraying pipe that the nitrogen introducing valve system communicates, be evenly distributed with spray nitrogen hole on this nitrogens spraying pipe, be connected with one at the oil exit pipe place and start the nitrogen relief valve simultaneously, pressure-reducing valve also sprays the pressure control device of nitrogen in fuel tank by nitrogens spraying pipe.Above-mentioned pressure control device combines by electric node manometer or pressure switch or the time relay or by small oil tank and sensitive switch.When the transformer breaking out of fire, the fuel tank top will produce the higher deep fat layer of temperature, and make the continuous vaporization of oil participate in burning, hygrosensor passed to the fire signal of being surveyed electromagnetic mechanism rapidly and opened draining valve this moment, when oil drain quantity acquires a certain degree and when producing a constant pressure drop, pressure control device will send signal enabling nitrogen relief valve, pressure-reducing valve also sprays nitrogen by nitrogens spraying pipe in fuel tank, the nitrogen that sprays into is also carried the cold oil of fuel tank bottom secretly and the deep fat formation convection current on top, the hot oil temperature on fuel tank top is descended, reduce the vaporization of oil, air in the fuel tank can be discharged from the nitrogen of the interior ejection of oil simultaneously, thereby fire is extinguished.
The utlity model has simple in structure, easy for installation, cost is low, blow-off velocity is fast, and shortened the maintenance time after transformer catches fire, and does not produce characteristics such as any pollution and degree of injury are little.The use of this device is not subjected to the restriction of any geographical environment, is in continuous automatic monitor state when operation, can monitor automatically the air pressure of self and the operating state of critical piece simultaneously.This device is compared for the alkane extinguishing device with water extinguisher and tooth, can save cost more than 80%, compares with external same device, and it is few to have its action control point and a running mechanism, advantages such as control sensitivity height.
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
Fig. 1 is the utility model normal condition structural representation.
Structural representation after the utility model started when Fig. 2 was the transformer breaking out of fire.
By shown in Figure 1,6 is that oil tank of transformer, 7 is that oil conservator shut off valve, 8 is that oil conservator, 4 is that oil exit pipe, 2 is draining valve, be provided with two or three hygrosensors 5 at the top of oil tank of transformer 6, this hygrosensor is by its signal sending element and 3 UNICOMs of Electromagnetic Control mechanism, and Electromagnetic Control mechanism is used for controlling quick unlatching draining valve 2.Two nitrogens spraying pipes 9 are housed in the bottom of fuel tank, and this nitrogens spraying pipe is connected with nitrogen cylinder 14 by check-valves 10, logical nitrogen pipe 11, nitrogen release electromagnetically operated valve 12 and pressure-reducing valve 13.Be connected with one at the oil exit pipe place and can start nitrogen release electromagnetically operated valve simultaneously.Pressure-reducing valve also sprays the pressure control device 1 of nitrogen by nitrogens spraying pipe in fuel tank, this pressure control device 1 is combined by the time relay and sensitive switch.When transformer breaks down, the Buchholz relay of transformer self sends early warning signal to this device, when fire for transformer (referring to Fig. 2), send actuating signal to the Electromagnetic Control mechanism of control draining valve rapidly by signal sending element after the hygrosensor detection of fires of this device, open the draining valve oil extraction fast, the oil conservator shut off valve cuts out simultaneously, avoids sending oil to the transformer that catches fire again.When oil drain quantity acquires a certain degree, just produce certain pressure drop in the fuel tank, then release electromagnetically operated valve to nitrogen and send actuating signal by pressure control device, making nitrogen discharge electromagnetically operated valve opens, height in the nitrogen cylinder press dry nitrogen and passes through pressure-reducing valve, be decompressed to and require pressure, and the nitrogens spraying pipe bottom logical nitrogen pipe arrival fuel tank, and by spray nitrogen hole ejection uniform on the nitrogens spraying pipe, along with the ejection of nitrogen, make the cold oil of fuel tank bottom flow to form uniformly and stir to fuel tank top, make the deep fat layer attenuate and the cooling on fuel tank top, the evaporating capacity of oil is reduced, Pen Chu nitrogen is discharged the air in the fuel tank simultaneously, causes combustion alkane condition to be destroyed rapidly, and reaches the purpose of fire extinguishing.
Claims (2)
1, a kind of oil extraction stirring-type transformer extinguishing device that is applicable to the transformer quick extinguishing, it includes oil tank of transformer, oil conservator, the oil conservator shut off valve, oil exit pipe, draining valve, it is characterized in that being provided with hygrosensor at the top of oil tank of transformer, draining valve is controlled by an electromagnetic mechanism that is connected with the hygrosensor signal sending element, at least be provided with one and nitrogen cylinder in the bottom of fuel tank, pressure-reducing valve, logical nitrogen pipe, check-valves, the nitrogens spraying pipe that the nitrogen introducing valve system communicates, be evenly distributed with spray nitrogen hole on this nitrogens spraying pipe, be connected with one at the oil exit pipe place and start the nitrogen relief valve simultaneously, pressure-reducing valve also sprays the pressure control device of nitrogen in fuel tank by nitrogens spraying pipe.
