Description
Technical field
The utility model relates to electricity, has the distribution board of the power supply of metal shell or distribution, transformer station, espespecially a kind of flame retardant type ring main unit.
Background technology
Looped network refers to ring distribution system, namely supply main forms a closed annular, power supply is powered to this ring main, the outside distribution of high-voltage switch gear is passed through from main line Shang Zai mono-tunnel one tunnel, such benefit is, each distribution branch road both can with its main line power taking source, left side, again can by main line power taking source on the right side of it, when left side, main line is out of order, it just continues to be powered from right side main line, and when right side main line is out of order, it just continues to be powered from left side main line, so, although general supply is single service, but obtain being similar to the material benefit of supplying power with double circuit from each distribution branch road, thus improve the reliability of power supply, so-called " ring main unit " is exactly that a switch cubicle (outlet switch cabinet) established by each distribution branch road, the bus of this switch cubicle is exactly a part for ring main simultaneously, in other words, ring main is coupled together by the bus of every platform outgoing line cabinet and jointly to form.Every platform outgoing line cabinet is just named " ring main unit ", in fact taking out separately ring main unit is the implication not seeing " looped network ", the rated current of these ring main units is all little, thus the high-voltage switch gear of ring main unit does not generally adopt baroque circuit breaker and takes the high voltage load switch of structure simply with high-tension fuse, that is, high-voltage switch gear in ring main unit is generally on-load switch, ring main unit on-load switch operates normal current, and excise short circuit current with fuse, both combines and instead of circuit breaker, certainly this can only be confined in certain capacity, such switch cubicle also can be used in the distribution system of non-ring network structure completely, so along with the extensive use of this switch cubicle, " ring main unit " has just jumped out the category of looped network distribution and to make a general reference with on-load switch be the high-tension switch cabinet of main switch.
Various control element is normally fitted through mounting panel and is fixed on cabinet by the ring main unit due to prior art, cabinet is generally metal structure, because cabinet inside is provided with fuse, cable vault, control cabinet, bus-bar room, earthed switch, electrical current is large, heat-dissipating is high, install intensive, owing to being in the security incidents such as power supply state can cause ring main unit on fire from explosion for a long time.
Summary of the invention
A kind of flame retardant type ring main unit is provided for the problems referred to above the utility model; this product structure reasonable standard; easy to use; the effect of flame-resistant insulation effectively can be played by the design of micarex; the design of inorganic fire-retarded layer simultaneously effectively can strengthen the flame retardant effect of single ring main unit; can effectively prevent burning things which may cause a fire disaster from spreading, protection neighbouring device facility.
Solve the problem, the utility model provides a kind of flame retardant type ring main unit, comprise cabinet, inorganic fire-retarded layer, micarex, PLASTIC LAMINATED, Fireproof cover, first adsorption layer, second adsorption layer, it is characterized in that: cabinet is the rectangle metal safe of hollow, cabinet inner surface is provided with inorganic fire-retarded layer, inorganic fire-retarded layer inside is provided with micarex, cabinet middle and upper part is provided with Fireproof cover, Fireproof cover is the metallic plate be obliquely installed, cabinet inner horizontal adjacent in the middle part of Fireproof cover is provided with PLASTIC LAMINATED, micarex top inner surface is provided with the second adsorption layer, second adsorption layer lower surface is provided with the first adsorption layer.
As further improvement of the utility model, described micarex thickness is 10 millimeters, and inorganic fire-retarded layer is magnesium hydroxide packed layer, and inorganic fire-retarded layer thickness is 5 millimeters.
As further improvement of the utility model, described first adsorption layer is Hydrogen soap zeolite packed layer, and the first adsorbent layer thickness is 20 millimeters, and the second adsorption layer is activated alumina packed layer, and the second adsorbent layer thickness is 10 millimeters.
Operation principle:
The utility model is by rational structural design, the effect of flame-resistant insulation effectively can be played by the micarex arranged in cabinet inside, being blown by cable when ring main unit breaking out of fire drops when cabinet is inner, owing to there being the existence of micarex, effectively can play the effect of flame-resistant insulation, the inorganic fire-retarded layer that magnesium hydroxide is filled simultaneously has good flame retardation effect, absorb the good result that heat is high, the Combination Design of Fireproof cover and PLASTIC LAMINATED can effectively prevent from flare is gone here and there simultaneously, burn out ring main unit top and cause large-area fire, the Combination Design of the first adsorption layer and the second adsorption layer simultaneously, effectively the noxious fume produced that burns can be adsorbed, first adsorption layer of being filled by Hydrogen soap zeolite has good heat insulation suction-operated, the second adsorption layer that activated alumina is filled has good suction-operated, can by the nitrogen dioxide produced that burns, sulfur dioxide pernicious gas adsorbs, prevent the harmful gases diffusion produced that burns.
The utility model compared with prior art has following beneficial effect:
1, the utility model is by rational structural design, the effect of flame-resistant insulation effectively can be played by the micarex arranged in cabinet inside, being blown by cable when ring main unit breaking out of fire drops when cabinet is inner, owing to there being the existence of micarex, effectively can play the effect of flame-resistant insulation, the inorganic fire-retarded layer that magnesium hydroxide is filled simultaneously has good flame retardation effect, absorbs the good result that heat is high;
2, the inorganic fire-retarded layer that magnesium hydroxide is filled simultaneously has good flame retardation effect, and absorb the good result that heat is high, the Combination Design of Fireproof cover and PLASTIC LAMINATED can effectively prevent from flare is gone here and there simultaneously, burns out ring main unit top and causes large-area fire;
3, the Combination Design of the first adsorption layer and the second adsorption layer while, effectively the noxious fume produced that burns can be adsorbed, first adsorption layer of being filled by Hydrogen soap zeolite has good heat insulation suction-operated, the second adsorption layer that activated alumina is filled has good suction-operated, the nitrogen dioxide that can produce burning, sulfur dioxide pernicious gas adsorb, and prevent the harmful gases diffusion produced that burns.
