Abstract
The utility model provides a lightning arrester, includes metal casing, insulating solid, goes up conducting rod, the explosion -proof piece of metal, conducting rod down, metal casing cup joints insulating solid, insulation solid inside is equipped with sealed cavity and the bottom is thin walled structure, be equipped with liquid silicon rubber in the sealed cavity, the upper end that liquid silicon rubber is connected to insulating solid is passed to the conducting rod axial, the explosion -proof piece of metal is including a plurality of pressure release hole and hug closely insulating solid bottom, through -hole, the insulating solid connection liquid silicon rubber that the explosion -proof piece of metal was equipped with is passed in proper order to conducting rod one end down, and earthing device is connected to the other end. Outside realizing the basic function who takes shelter from the thunder, the airtight sky cavity pressure value of working as lightning arrester exceedes the setting value, and then the thin walled structure bottom the insulating solid breaks, and the pressure release orifice flow play of the explosion -proof piece of metal is followed to the liquid silicon rubber of inside, the circuit connection of conducting rod and last conducting rod under the disconnection to accomplish the conservation work of circuit, avoid the lightning arrester initiation accident of blasting.
Description
Technical field
This utility model belongs to lightning protection of electric appliance field, is specifically related to a kind of spark gap.
Background technology
Current all kinds of spark gaps are designed with various riot gear, and precise structure is complicated, is greatly improved and is correlated with into
This.Additionally due to interior arrangement is the most accurate so that fault rate is higher.
Utility model content
For the problems referred to above, this utility model provides the spark gap of a kind of simple in construction.
A kind of spark gap, including metal shell, solid insulation, upper conducting rod, metal explosion-proof sheet, lower conducting rod,
Described metal shell socket solid insulation, is provided with sealing cavity inside described solid insulation and bottom is thin-walled knot
Structure, is provided with liquid silastic in described sealing cavity, described conducting rod connects liquid silicon axially across solid insulation
The upper end of rubber, described metal explosion-proof sheet includes several relief holes and is close to bottom solid insulation, described under
Conducting rod one end sequentially passes through through hole, the solid insulation connection liquid silastic that metal explosion-proof sheet is provided with, the other end
Connecting earthing device.
Described metal shell includes that upper shell, lower house, described upper shell are threadably secured with lower house and is connected.
Described upper shell is provided with threaded mounting hole.
Described solid insulation upper end is provided with installation lid, and described lid of installing is for fixing upper conducting rod.
Described installation is provided with sealing ring between lid and solid insulation, and described sealing ring seals the close of cavity for improving
Feng Xing.
Beneficial effect: outside realizing lightning-arrest basic function, when the internal pressure of spark gap is excessive or temperature mistake
When height causes the interior pressure of closed cavity to increase, if interior force value exceedes setting value, then thin bottom solid insulation
Wall construction ruptures, and internal liquid silastic flows out from the relief hole of metal explosion-proof sheet, disconnects lower conducting rod with upper
The circuit of conducting rod connects, thus completes the protection work of circuit, it is to avoid spark gap occurs blast accidents caused.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
1 metal shell, 11 upper shells, 12 lower houses, 2 solid insulation, conducting rod, 4 metal explosion-proof on 3
Sheet, 41 relief holes, 5 times conducting rods, 6 liquid silastics, 7 installation lids, 8 sealing rings.
Detailed description of the invention
Below in conjunction with the accompanying drawings, this utility model is further illustrated by embodiment:
A kind of spark gap, including metal shell 1, solid insulation 2, upper conducting rod 3, metal explosion-proof sheet 4, under
Conducting rod 5, described metal shell 1 is socketed solid insulation 2, and described solid insulation 2 is internal is provided with sealing cavity
And bottom is thin-wall construction, being provided with liquid silastic 6 in described sealing cavity, described conducting rod is axially across absolutely
Edge solid 2 connects the upper end of liquid silastic 6, and described metal explosion-proof sheet 4 includes several relief holes 41 also
And be close to bottom solid insulation 2, described lower conducting rod 5 one end sequentially pass through through hole that metal explosion-proof sheet 4 is provided with,
Solid insulation 2 connects liquid silastic 6, other end connecting earthing device.Realize lightning-arrest basic function it
Outward, when the internal pressure of spark gap is excessive or the too high interior pressure causing closed cavity of temperature increases, if intrinsic pressure
Force value exceedes setting value, then the thin-wall construction bottom solid insulation 2 ruptures, and internal liquid silastic 6 is from gold
The relief hole 41 belonging to burst disk 4 flows out, and disconnects lower conducting rod 5 and is connected with the circuit of upper conducting rod 3, thus
Complete the protection work of circuit, it is to avoid spark gap occurs blast accidents caused.
Described metal shell 1 includes that upper shell 11, lower house 12, described upper shell 11 lead to lower house 12
Cross the connection that is screwed, it is simple to install.
Described upper shell 11 is provided with threaded mounting hole, can fix spark gap by outside fixed mount.
Described solid insulation 2 upper end is provided with installation lid 7, and described lid 7 of installing is for fixing upper conducting rod 3, anti-
Conducting rod 5 under upper 3 times slips of conducting rod.
Described installation is provided with sealing ring 8 between lid 7 and solid insulation 2, improve the sealing sealing cavity.
Obviously, above-described embodiment of the present utility model is merely to illustrate that this utility model example, and
The not restriction to embodiment of the present utility model.For those of ordinary skill in the field, upper
State bright on the basis of can also make change or the variation of other multi-forms.Here without also cannot be to all
Embodiment give poor example.And these belong to that connotation of the present utility model amplified out obvious
Change or variation still fall within protection domain of the present utility model.
