Description
Technical field
The utility model relates to fuse, relates to a kind of fuse structure with voltage levels in particular.
Background technology
Whether the fusing of fuse depends on the size of the electric current that flows through it, irrelevant with the operating voltage of circuit.The rated voltage of fuse
BePropose from safe handling fuse angle, it is the maximum operating voltage that fuse is in the circuit that safe work state settles.This explanation fuse can only be placed in the circuit of operating voltage smaller or equal to Fuse Voltage Rating, and only in this way fuse could safe and effective work, otherwise, when blown fuse, will occur continuing arcing and
QuiltVoltage breakdown and the phenomenon that endangers circuit.
The rated voltage of fuse is often referred to the maximum voltage value that can bear after fuse disconnects, and Fuse Voltage Rating equals or greater than circuit voltage.The rated voltage of fuse will adapt to the line voltage distribution grade.Fuse has the electric pressure difference, and such as under the identical situation of rated current, the fuse of 10kV and the difference of 220V fuse are just very big, though identical electric current can both make its fusing, if voltage is too high, the fracture of fusing just can not guarantee insulation safety.So high-tension fuse can be used on the low pressure, but just can not being used on the high pressure of low pressure, low-tension fuse is used on the high pressure, and the fracture of fusing will produce sustained arc, can not deenergization.Be high can being used in the low circuit of voltage of general electric pressure, top voltage value refers to and can be applied on the different electric pressures, because same electric current its capacity under different voltage is different, if what voltage was lower is applied in the high voltage loop, when situation such as being short-circuited, may cause other security incident because the fuse breaking capacity causes the fuse demolition inadequately.
Fix because of existing fuse electric pressure, the normal voltage rated value of general insurance silk is 24V, 32V, 48V, 60V, 125V, 250V, 300V, 500V, 600V.Fuse can use being not more than under the voltage of its rated voltage, but generally is not agreed use in the circuit of circuit voltage greater than Fuse Voltage Rating.On electric pressure, there is limitation in general fuse, thus the utility model the structure of fuse is made improvements, to improve its electric pressure.
The utility model content
The purpose of this utility model is to provide a kind of fuse structure with high pressure grade, and it has increased the electric pressure of fuse, uses to have more selectivity.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of fuse structure with voltage levels, include substrate, two opposite ends of substrate are coated with the copper-base sheet, fusable links is connected between the two copper-base sheets, be connected with at least two fusable links between the two copper-base sheets, connect before and after between each bar fusable links, two adjacent fusable links are connected by a sheet metal respectively in the intersection, and fusable links is connected on the sheet metal.
Described fusable links is connected on the sheet metal by scolding tin, ratio-frequency welding, ultrasonic bond, butt-joint or binding.
Be broken line between the described fusable links and connect arrangement.
Linearly connect between the described fusable links and arrange.
After adopting said structure, fuse of the present utility model is between the copper electrode sheet at its two ends, be connected with at least two fusable links, each fusable links is being cascaded, thereby can go up the fusable links of varying number according to the user demand series connection, improve the electric pressure of fuse, and the fusable links that becomes broken line to arrange can strengthen the breaking capacity of fuse to a certain extent.

Embodiment
In order further to explain the technical solution of the utility model, the utility model is elaborated below by specific embodiment.
As shown in Figure 1, the fuse structure with voltage levels of the present utility model includes substrate 1, and two opposite ends of substrate 1 are coated with copper-base sheet 2, and fusable links 3 is connected between the two copper-base sheets 2.
In the utility model, for increasing the fuse electric pressure, between two copper-base sheets 2, be connected with at least two fusable links 3, connect before and after between each bar fusable links 3, two adjacent fusable links 3 are connected by a sheet metal 4 respectively in the intersection, and fusable links 3 is connected on the sheet metal 4 by scolding tin 5.When fusable links 3 connects in front and back, but linear array be connected on the same vertical curve, as shown in Figure 1 and Figure 2, certainly, also can connect between many fusable links to arrange and be broken line, as shown in Figure 3, Figure 4.
Simultaneously, respectively by a sheet metal 4 series connection, fusable links 3 is connected on the sheet metal 4 by scolding tin 5 fusable links 3 of Xiang Jiaoing in the intersection in twos, and certainly, fusable links 3 also can be connected on the sheet metal 4 by ratio-frequency welding, ultrasonic bond, butt-joint or binding mode.It can go up the fusable links 3 of varying number according to the user demand series connection, different series systems as shown in the figure, many fusable links 3 of series connection between the copper-base sheet 2 at fuse two ends, connecting at least two fusable links 3 in the series connection between the two copper-base sheets 2, article one, the two ends of fusable links 3 constitute a unit voltage grade, N sheet metal 4 arranged in fuse, N+1 bar fusable links 3 is just arranged, rated voltage as the fuse of a former fusable links is 63V, then just can reach 63*(N+1 at the fuse that is in series with N+1 bar fusable links 3) V, thus the electric pressure of raising fuse.
Further; cause is that fuse is series in the protected circuit generally; when the electric current of protected circuit surpasses setting; and through behind the certain hour; heat fusing fusable links by fuse self generation; circuit is disconnected; thereby play the effect of protection; this moment is for fuse; because of its in the fusable links 3 of electric current by in fuse; generally disconnect from the middle part during fusing; for being many fusable links that broken line type is arranged, disconnect from the middle part straight line during fusable links fusing, 3 of fusable links of arranging for the broken line midpoint of a fusable links therein just directly disconnect; the whole fusing of fuse required time is shorter, thereby also can improve the breaking capacity of fuse to a certain extent.
Above-described embodiment and graphic and non-limiting product form of the present utility model and style, any person of an ordinary skill in the technical field all should be considered as not breaking away from patent category of the present utility model to its suitable variation or modification of doing.
