Abstract
The invention relates to a special fuse for ozone generators. The fuse comprises a ceramic shell, two plugs, a spring, a fuse wire and two connecting screw rods. The ceramic shell is of a hollow tubular structure, the plugs are fixed at two ends of the ceramic shell, silica gel is arranged between each plug and the ceramic shell, each connecting screw rod is fixed on the corresponding plug in an inserted manner, the spring and the fuse wire are arranged in the ceramic shell, one end of the spring is connected with one connecting screw rod by welding, the other end of the spring is connected with the fuse wire by welding, and the other end of the fuse wire is connected with the other connecting screw rod by welding. Heat emission of the fuse is lowered, and meanwhile the requirement on performance of arc extinction is met.
Description
Technical field
The present invention relates to a kind of fuse, specifically a kind of ozone generator special safety silk, the insurance device of high-frequency current electric equipment, is specially adapted to ozone generator field.
Background technology
In the special high frequency fuse of current ozone generator, due to reasons such as fuse are selected long, and resistivity is excessive, when ozone generator works, high-frequency current causes caloric value excessive by fuse.And ozone generator works in the high pressure of more than 3000v, so can phenomenon of arc discharge be produced during fuse failure, in order to arc extinguishing just must in protective tube filled stone sand, because the heat conductivility of quartz sand is good, so a large amount of heats will pass to ozone generator inside, and the characteristic of ozone itself is more responsive to high temperature, too high temperature can accelerate the decomposition of ozone.Not only can reduce the output of ozone, also can increase the waste of electric energy.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of ozone generator special safety silk, also will reach the performance requirement of arc extinguishing while what reduces protective tube heating.
For solving the problems of the technologies described above, technical scheme of the present invention is:
A kind of ozone generator special safety silk, comprise ceramic shell, plug, spring, fuse and connecting screw rod, described ceramic shell is the tubular structure of hollow, the quantity of described plug is two, plug is fixed on ceramic shell two ends, silica gel is provided with between plug and ceramic shell, the quantity of described connecting screw rod is two, connecting screw rod is plug-type to be fixed on plug, described spring and fuse are arranged in ceramic shell, described spring one end and a connecting screw rod are welded to connect, the spring other end and fuse are welded to connect, the other end and another connecting screw rod of described fuse are welded to connect, the length of described fuse is 9-11mm.
Above-mentioned a kind of ozone generator special safety silk, wherein, described spring is in extended state.
Beneficial effect of the present invention is:
The present invention's not filled stone sand in ceramic shell, but selection air, because it is much lower that air conduction ability is compared to quartz sand, in order to the function of arc extinguishing can be played, make separate fast during fuse failure, to adopt spring and fuse link, when fuse failure, under the snapback of spring being in extended state, fuse failure place can be separated fast thus reach the effect of arc extinguishing.
The length of fuse is set to 9-11mm, so just effectively can reduces the caloric value of protective tube entirety.
Be provided with silica gel between plug and ceramic shell, add sealing property, ensure that the fail safe of use.
Accompanying drawing explanation
Fig. 1 is cutaway view of the present invention.
Embodiment
A kind of ozone generator special safety silk as shown in the figure, comprise ceramic shell 1, plug 2, spring 3, fuse 4 and connecting screw rod 5, described ceramic shell 1 is the tubular structure of hollow, the quantity of described plug 2 is two, plug 2 is fixed on ceramic shell 1 two ends, silica gel 6 is provided with between plug 2 and ceramic shell 1, the quantity of described connecting screw rod 5 is two, connecting screw rod 5 is plug-type to be fixed on plug 2, described spring 3 is arranged in ceramic shell 1 with fuse 4, described spring 3 one end and a connecting screw rod 5 are welded to connect, spring 3 other end and fuse 4 are welded to connect, the other end and another connecting screw rod 5 of described fuse 4 are welded to connect, the length L2 of described fuse 4 is 10mm, the length L1 of described ceramic package 1 is 11cm, described spring 3 is in extended state.
The present invention's not filled stone sand in ceramic shell, but selection air, because it is much lower that air conduction ability is compared to quartz sand, in order to the function of arc extinguishing can be played, make separate fast during fuse failure, to adopt spring and fuse link, when fuse failure, under the snapback of spring being in extended state, fuse failure place can be separated fast thus reach the effect of arc extinguishing.
The length of fuse is set to 10mm, so just effectively can reduces the caloric value of protective tube entirety.
Be provided with silica gel between plug and ceramic shell, add sealing property, ensure that the fail safe of use.
Here description of the invention and application is illustrative, not wants by scope restriction of the present invention in the above-described embodiments, and therefore, the present invention is not by the restriction of the present embodiment, and the technical scheme that any employing equivalence replacement obtains is all in the scope of protection of the invention.
