Description
Technical field
The utility model relates to a kind of electric equipment, and in particular, it relates to a kind of self-extinguishing switch cubicle.
Background technology
Switch cubicle is a kind of electric equipment, and Main Function is in electric power system, to generate electricity, in transmission of electricity, distribution and electric energy transfer process, carry out folding, control and protection power consumption equipment; Can install and fix for various electric components, can maintain easily management like this, and facilitate wiring to install; A large amount of electric components are installed in switch cubicle, and these electric components produce a large amount of heats when energising, can cause inside switch cabinet temperature to raise; And electric component is while being in for a long time the environment of high temperature, or during electric component overload, can cause the aging breakage of insulating barrier of current-carrying part, cause inside switch cabinet short circuit, thereby cause fire; Traditional switch cubicle does not have automatic fire extinguisher after on fire, has certain room for improvement.
Utility model content
The deficiency existing for prior art, the purpose of this utility model be to provide a kind of can be at the self-extinguishing switch cubicle of switch cubicle rear self-extinguishing on fire.
For achieving the above object, the utility model provides following technical scheme: a kind of self-extinguishing switch cubicle, comprise cabinet and for the installing rack of mounting electrical element, on described cabinet, be provided with trigger equipment and fire suppression bottle, reactant is set in described fire suppression bottle and triggers agent, in described fire suppression bottle, be also provided with the separator for reactant and triggering agent are separated, on described fire suppression bottle, be provided with jet pipe, in described jet pipe, be provided with diaphragm seal, described jet pipe is arranged in cabinet, described trigger equipment comprises bimetal leaf and the needle tubing being all arranged in cabinet, the side opening that offers pore on described needle tubing and be communicated with pore, described bimetal leaf comprises active layers and passive layer, described active layers is conflicted and is connected with passive layer, described needle tubing is located in fire suppression bottle, the corresponding separator in described needle tubing one end and the other end are conflicted on passive layer.
By adopting technique scheme, electric component is generally all arranged on installing rack, and when electric component on installing rack is on fire, bimetal leaf is heated, bimetal leaf is welded by active layers and passive layer, active layers is generally made by manganin manganin alloy, passive layer is made by dilval, the thermal coefficient of expansion of active layers is greater than the thermal coefficient of expansion of passive layer, so when bimetal leaf is heated, the deformation of active layers is greater than the deformation of passive layer, thereby make bimetal leaf towards passive layer curving, and temperature is higher, degree of crook is larger, bimetal leaf is when bending to a certain degree, can make needle tubing puncture separator, side opening on needle tubing can make the reactant of separator both sides and trigger agent and mix with pore, and can also control reactant and the reaction rate that triggers agent, make reactant and triggering agent generate stably carbon dioxide, reactant is respectively the aluminum sulfate solution of high concentration and the sodium bicarbonate solution of high concentration with triggering agent, after both haptoreactions, can in fire suppression bottle, produce a large amount of carbon dioxides, pressure in fire suppression bottle is uprised, carbon dioxide breaks through diaphragm seal, by jet pipe, be ejected on installing rack, due to carbon dioxide easy cleaning, and can not damage electric component, after fire extinguishes, the good inner electric component of maintenance, can also continue to use, this design can be in switch cubicle rear self-extinguishing on fire.
The utility model is further set to: the cross section of described bimetal leaf is circular arc, and described bimetal leaf one end is fixed on installing rack and the other end is connected with needle tubing.
By adopting technique scheme, bimetallic one end be to be fixed on installing rack, so can be not crooked, when installing rack is on fire, temperature uprises, and one end of the corresponding needle tubing of bimetal leaf is crooked, and needle tubing is to conflict on passive layer, bimetal leaf is crooked towards needle tubing, makes needle tubing puncture separator, thereby makes reactant and trigger agent haptoreaction; This design can trigger by bimetal leaf the effect of self-extinguishing.
The utility model is further set to: described diaphragm seal outer rim is fixed on nozzle wall.
By adopting technique scheme, because diaphragm seal outer rim is fixed on nozzle wall, thereby block jet pipe, prevent that reactant and the extinguishing chemical in fire suppression bottle from spilling from jet pipe, once carbon dioxide, be flushed on diaphragm seal, carbon dioxide can break through diaphragm seal and spray from jet pipe; This design can make to block jet pipe, and when reactant reacts with triggering agent, by carbon dioxide, is broken through.
The utility model is further set to: described reactant is made by sodium bicarbonate solution, and described triggering agent is made by aluminum sulfate solution.
By adopting technique scheme, if water is put out a fire, can cause electric component short circuit, if use dry-chemical fire extinguishing, can make electric component scrap, and the words of carbon dioxide are gas, can after fire extinguishing, not remain in electric component; So reactant is respectively the aluminum sulfate solution of high concentration and the sodium bicarbonate solution of high concentration with triggering agent, after both haptoreactions, can in fire suppression bottle, produce a large amount of carbon dioxides, pressure in fire suppression bottle is uprised, carbon dioxide breaks through diaphragm seal, by jet pipe, is ejected on installing rack; And carbon dioxide easy cleaning, and can not damage electric component, after fire extinguishes, the good inner electric component of maintenance, can also continue to use; This design can, after fire suppression bottle fire extinguishing, not damage electric component.
The utility model is further set to: on described jet pipe, be connected with nozzle, described nozzle is towards installing rack setting.
By adopting technique scheme, while spraying from jet pipe due to carbon dioxide, scope is less, and injection is even not, so connect nozzle on jet pipe, when carbon dioxide is from nozzle ejection, can spray to uniformly installing rack, and adjust flow velocity and the pressure of gas; This design can improve fire extinguishing effect.
