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 ring main unit with explosion prevention function.
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.
In switch running, there is the inner arcing of gas tank because the reasons such as misoperation or the failure of interruption of switch own cause sometimes, inner arcing can go out huge energy in abrupt release, gas tank is caused to burst, if the pressure relief device of now not setting in advance and pressure release passage, with regard to easily occurring indefinite due to explosion energy release direction, personnel casualty accidents that is that cause occurs, the structure of metal explosion-proof sheet simultaneously, easily forms bridging short circuit or impacts formation casing to casing damaged after explosive disintegration.
Summary of the invention
A kind of ring main unit with explosion prevention function is provided for the problems referred to above the utility model; this device structure specification, easy to use, by the appropriate design to burst disk and pressure release passage; can effectively be gone out by earth pressure release, protection casing and other structures are not fed through to.
Solve the problem, the utility model provides a kind of ring main unit with explosion prevention function, comprise cabinet, burst disk, piston, spring, blast pipe, steam vent, explosion-protection equipment, pressure release passage, magnet, iron plate, it is characterized in that: cabinet is the rectangular structure of hollow, cabinet bottom is provided with explosion-protection equipment, explosion-protection equipment top is provided with burst disk, burst disk is the epoxy sheet including iron plate, explosion-protection equipment bottom is provided with pressure release passage, curved portions is set to bottom pressure release passage, curved portions upper surface is provided with some magnet, magnet top is in same level, pressure release passage lower right side is provided with blast pipe, spring is provided with on the right side of blast pipe inwall, the other end of spring is provided with piston, on body between on the right side of piston and blast pipe, symmetry runs through and is provided with a pair steam vent.
As further improvement of the utility model, on the left of described blast pipe inwall, be provided with water accepting layer.
As further improvement of the utility model, described blast pipe left part is provided with filter screen.
Operation principle:
The utility model is by reasonably improving the explosion-protection equipment of ring main unit, eliminate original metal explosion-proof sheet, by using the inner epoxy resin containing iron plate, because epoxy resin forms a coating function to iron plate, can effectively prevent burst disk from bursting rear formation bridging short circuit, epoxy resin hardness is far below metal simultaneously, a good buffering effect can be formed at contact casing or miscellaneous part, the impact failure produced casing or parts is little, simultaneously by being provided with curved portions bottom pressure release passage, effectively can strengthen the impact resistance of pressure release passage, the Magnet design of same vertical separation, the epoxy resin burst effectively can be caught, prevent it from impacting curved portions, the magnet of proper alignment also has the effect that magnetic field strengthens simultaneously, the design of blast pipe upper piston structure can form repeatedly pressure release, filter screen can effectively prevent chip from impacting cabinet outside by blast pipe simultaneously, cause other potential safety hazard, on blast pipe, the steam vent of symmetrical structure can form the effect of hitting that mutually recoils in exhaust process simultaneously, effective protection blast pipe, hit due to the recoil of power when preventing blast pipe to be vented and damage.
The utility model compared with prior art has following beneficial effect:
1, the utility model is by reasonably improving the explosion-protection equipment of ring main unit, eliminate original metal explosion-proof sheet, by using the inner epoxy resin containing iron plate, because epoxy resin forms a coating function to iron plate, can effectively prevent burst disk from bursting rear formation bridging short circuit, epoxy resin hardness is far below metal simultaneously, can form a good buffering effect at contact casing or miscellaneous part, and the impact failure produced casing or parts is little;
2, simultaneously by being provided with curved portions bottom pressure release passage, effectively can strengthen the impact resistance of pressure release passage, the Magnet design of same vertical separation, the epoxy resin burst effectively being caught, prevent it from impacting curved portions;
3, the magnet of proper alignment also has the effect of magnetic field enhancing simultaneously; the design of blast pipe upper piston structure can form repeatedly pressure release; filter screen can effectively prevent chip from impacting cabinet outside by blast pipe simultaneously; cause other potential safety hazard; on blast pipe, the steam vent of symmetrical structure can form the effect of hitting that mutually recoils in exhaust process simultaneously; effective protection blast pipe; hit due to the recoil of power when preventing blast pipe to be vented and damage; water accepting layer can effectively prevent external moisture from corroding pressure release passage, keeps the drying of pressure release passage.
