Background technique:
Photovoltaic power generation generallys use gamut protection with American Unit Substation high-pressure side and (is hereinafter referred to as fused with limiting fuse
Device)+on-load switch protected.When assembly, mounting flange, tank wall flange and fuse mounting flange are welded on oil tank wall
Match, fuse shell is structure as a whole with fuse mounting flange, and it is one that fusible core of fuse is connected through a screw thread with fusible core bracket
Body.After the assembly is completed, fusible core of fuse and fusible core bracket are inserted into fuse enclosure interior to fuse shell, are fastened by external screw thread
On fuse shell, assembly is completed.
The structure during normal use, has no problem substantially.But under the conditions of some specific, because calculating the originals such as deviation
Cause can make the ampere-time characteristic of fusible core of fuse and higher level's protection fail intact matching, cause fusible core in fusing, fuse housing
Internal pressure abruptly increase, sharply generates heat and fusible core of fuse and fusible core bracket is made to break through the externally threaded coupling mechanism force of fuse,
It is produced out of shell.Such as extraneous suitable condition, the risk for causing secondary disaster will be generated.
Summary of the invention:
The utility model is to provide a kind of anti-high pressure gamut protection to solve the above-mentioned problems of the prior art
Structure is produced with limiting fuse fusible core.
Technical solution used by the utility model has: a kind of anti-high pressure gamut protection is produced with limiting fuse fusible core
Structure, including fuse and fuel tank, the fuse include fuse shell, fuse flange, fusible core bracket and fusible core, described
Fuse shell and fuse flange are integrally formed, and fusible core and fusible core bracket are placed in fuse housing body, and fusible core and fusible core
Bracket, which is connected through a screw thread, to be integrated, and tank wall flange is equipped on the tank wall of fuel tank, and the tank wall flange and fuse flange are solid
Fixed connection, further includes shield, the shield is fixedly connected with the fuse flange of fuse；
The shield includes shield fixed plate and installation foot, and the shield fixed plate is circular configuration, several installation feet
It is arranged along the circumferencial direction of shield fixed plate, and one end of installation foot is fixedly connected by bolt with shield fixed plate, installation
Foot is fixedly connected with fuse flange.
Further, the installation foot has the ontology of a strip, and 90 ° of bendings are simultaneously in the opposite direction at the both ends of ontology
Form installation side.
Further, the installation side is equipped with mounting hole.
Further, the center point of the shield fixed plate is equipped with through-hole.
Further, there are four installation foot is set.
Further, the tank wall flange is equipped with and is welded with screw rod, and fuse flange and installation foot are connected on screw rod.
The utility model has the following beneficial effects:
Producing when the utility model effectively prevents fusible core of fuse to fuse improves the safety of product, reduces
Accident probability.
Detailed description of the invention:
Fig. 1 is the utility model structure chart.
Fig. 2 is the main view of shield in the utility model.
Fig. 3 is the left view of shield in the utility model.
Specific embodiment:
The utility model will be further described below with reference to the accompanying drawings.
Such as Fig. 1 to Fig. 3, a kind of anti-high pressure gamut protection of the utility model produces structure with limiting fuse fusible core, packet
Fuse 1, fuel tank and shield 3 are included, fuse 1 includes fuse shell 11, fuse flange 12, fusible core bracket 13 and fusible core
14, fuse shell 11 and fuse flange 12 are integrally formed, and fusible core 14 and fusible core bracket 13 are placed in fuse shell 11,
And fusible core 14 is connected through a screw thread with fusible core bracket 13 and is integrated, and tank wall flange 21, tank wall flange are equipped on the tank wall of fuel tank
21 are fixedly connected with fuse flange 12, and shield 3 is fixedly connected with the fuse flange 12 of fuse 1.
Shield 3 includes shield fixed plate 31 and installation foot 32, and shield fixed plate 31 is circular configuration, 4 installation feet 32
It is arranged along the circumferencial direction of shield fixed plate 31, and one end of installation foot 32 connects by the way that bolt and shield fixed plate 31 are fixed
It connects, installation foot 32 is fixedly connected with fuse flange 12.
Installation foot 32 has the ontology 321 of a strip, and the both ends of ontology 321 90 ° of bendings and are formed in the opposite direction
Side 322 is installed, is equipped with mounting hole on installation side 322.
The center point of shield fixed plate 31 is equipped with through-hole 310, which can observe fuse 1, also can be with winding displacement.
It being equipped on tank wall flange 21 and is welded with screw rod 22, fuse flange 12 and installation foot 32 are connected on screw rod 22,
It is threadedly coupled nut on screw rod 22, fuse flange 12, tank wall flange 21 and shield 3 are locked.
The case of scene operation becomes, if removing 4 fastening nuts simultaneously installs shield 3, has from fuse Method for Installation
The risk of blue face oil leak.To adapt to the operating condition, shield 3 is designed as breakdown structure (shield fixed plate 31 by the utility model
