Abstract
A kind of protective case improving the resistance to voltage levels of znr valve block, can solve to be easy impaired technical problem when existing znr valve block is in use；Including protective sheath ontology, described this ontology of protective sheath is mounted on the outer wall of znr valve block；Umbrella skirt construction is laterally set around the protective sheath body outer wall.The present invention have many advantages, such as structure it is simple, it is safe and reliable, increase creepage distance; protective sheath is installed on znr valve block outer wall; both the creepage distance on znr device surface can have been increased; damage when can reduce transport, installation, use again to znr valve block; influence of some unfavorable factors to znr valve block is greatly reduced, the service life of znr valve block is effectively increased.
Description
Technical field
The present invention relates to znr valve block protection technique fields, and in particular to a kind of raising zinc oxide is non-thread
The protective case of the property resistance to voltage levels of resistor valve sheet.
Background technique
Common element of the znr valve block as Hyper-Voltage of Power Systems overcurrent prevention and control field, has
Good nonlinear wind vibration is administered in product extensively in overcurrent such as the demagnetizations such as over-voltage protector, arrester cabinet, blockings
It uses.Znr valve block is deposited in 8/20us, 4/10us, 2/5us, 0.7/1.5us great current impact test
Punch-through is being caused because znr valve block surface creep distance is inadequate；It is easily caused in transport, installation, use
The damage of znr valve block, has significant effect znr valve block.It is badly in need of a kind of raising now
To zinc oxide nonlinear electricity when the surge voltage tolerance level of znr valve block and reduction transport, installation, use
Hinder the safeguard measure of the damage of valve block.
Summary of the invention
A kind of protective case improving the resistance to voltage levels of znr valve block proposed by the present invention, can solve existing
Znr valve block is easy impaired technical problem when in use.
To achieve the above object, the invention adopts the following technical scheme:
A kind of protective case improving the resistance to voltage levels of znr valve block, including protective sheath ontology, the protection shield
This ontology is covered to be mounted on the outer wall of znr valve block；
Umbrella skirt construction is laterally set around the protective sheath body outer wall.
Further, the protective sheath ontology is made using electric power of composite insulator silicon rubber material.
As shown from the above technical solution, the protective case of the raising resistance to voltage levels of znr valve block of the invention,
The protective sheath installs protective sheath on znr valve block outer wall, the present invention have structure is simple, safety can
It leans on, increase the advantages that creepage distance, protective sheath is installed on znr valve block outer wall, can both increase oxidation
The creepage distance on zinc nonlinear resistor surface, but can reduce transport, installation, use when to znr valve block
Damage, greatly reduce influence of some unfavorable factors to znr valve block, it is non-to effectively increase zinc oxide
The service life of linear resistance valve block.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiment of the present invention, instead of all the embodiments.
As shown in Figure 1, the protective case of the resistance to voltage levels of znr valve block is improved described in the present embodiment, including
Protective sheath ontology 1；There is multiple tracks umbrella skirt construction 11 on 1 outer wall of protective sheath ontology；The protective sheath 1 is mounted in zinc oxide
On the outer wall of nonlinear resistor valve sheet.
The protective sheath ontology 1 is made of electric power of composite insulator silicon rubber material.
Multiple tracks full skirt is horizontally arranged on 1 outer wall of protective sheath ontology, the full skirt is lateral umbrella bulge-structure,
Bulge-structure size can be identical also not identical, for improving the surge voltage tolerance level of znr valve block and subtracting
Damage when small transport, installation, use to znr valve block.
The protective sheath 1 is mounted on the outer wall of znr valve block；The protective sheath 1 and zinc oxide
Between nonlinear resistor valve sheet, a kind of high-insulativity, leakproofness, ageing-resistant, free from corrosion single-component room temperature vulcanized silicon rubber are used
Glue sticking, spontaneous curing is in high-impedance state at room temperature.
In conclusion the protective sheath of the embodiment of the present invention can both increase climbing for znr device surface
Electrical distance, and damage to znr valve block when can reduce transport, installation, using, greatly reduce
Influence of the unfavorable factor to znr valve block, effectively increase znr valve block uses the longevity
Life.
The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although with reference to the foregoing embodiments
Invention is explained in detail, those skilled in the art should understand that: it still can be to aforementioned each implementation
Technical solution documented by example is modified or equivalent replacement of some of the technical features；And these modification or
Replacement, the spirit and scope for technical solution of various embodiments of the present invention that it does not separate the essence of the corresponding technical solution.
