Abstract
The utility model, which relates to the field of the low-voltage electrical equipment control technology, particularly discloses an oil-cooled type quick fuse. The quick fuse comprises a fusion tube, wherein conductive connecting boards are arranged at two ends of the fusion tube; the space between the conductive connecting boards and the fusion tube is sealed by fluororubber or polyfluortetraethylene. Besides, a sterling silver fusant is arranged in the middle of the fusion tube, wherein a plurality of circular holes are punched on the sterling silver fusant; and the two ends of the fusant are welded to the conductive connecting boards arranged at two ends of the fusion tube by connecting sheets. According to the utility model, the provided oil-cooled type quick fuse has advantages of good oil-proof, explosion-proof, and sealing properties, good breaking capacity, fast breaking speed, low breaking I<2> t value and low power consumption and the like.
Description
Technical field
The utility model relates to the low voltage electrical equipment technical field, relates in particular to a kind of fast acting fuse for the integrated semiconductor equipment protection of high-power silicon semiconductor device oil-cooled transformation rectification.
Background technology
Existing fast acting fuse for rectifying tube or thyristor and the complete sets of equipment protection thereof comprises self cool fast acting fuse and water-cooled busbar cooled fast acting fuse etc.; be operation use in air ambient; because the poor-performings such as grease proofing, explosion-proof, the sealing of these type fuse products, so it can not satisfy the requirement of the integrated semiconductor equipment protection of high-power silicon semiconductor device oil-cooled transformation rectification in actual applications well.
The utility model content
The purpose of this utility model is, proposes a kind of oil-cooled quick-acting fuse, and its compact conformation, easy for installation has comparatively good grease proofing, explosion-proof and sealing property.
For achieving the above object, the utility model provides a kind of oil-cooled quick-acting fuse, comprise that two ends are with the fusion tube of conductive connection plates, sealed by fluorubber or polytetrafluoro between described conductive connection plates and the fusion tube, be provided with the fine silver melt processed of a plurality of circular holes of punching out on it in the middle of this fusion tube, the two ends of this melt are welded on the conductive connection plates at fusion tube two ends by brace.
Wherein, be filled with the quartz sand that silicate solidifies in the described fusion tube.
In addition, the outside of described fusion tube also is equipped with a blown fuse indicator.
Oil-cooled quick-acting fuse of the present utility model; the advantages such as it has grease proofing, explosion-proof, good seal performance and breaking capacity is large, breaking speed is fast, disjunction I2T value and power consumption are little; its product can be used in the oil immersed type rectifier of the electrolytic etching of metal such as chemical industry electrolysis and aluminium, nickel; also can be used in other industrial oil immersion formula convertor equipment, can satisfy well the requirement of the integrated semiconductor equipment protection of high-power silicon semiconductor device oil cooling transformation rectification.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Accompanying drawing 1 is the structural representation of a specific embodiment of the utility model.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, the utility model provides a kind of oil-cooled quick-acting fuse, it comprises that two ends are with the fusion tube 6 of conductive connection plates 1, seal by fluorubber or polytetrafluoro 7 between described conductive connection plates 1 and the fusion tube 6, in the middle of this fusion tube 6, also install the fine silver melt 4 processed of a plurality of circular holes of punching out on it, the two ends of melt 4 are welded on the conductive connection plates 1 at fusion tube two ends by conductive connecting piece 3, all the other space-fillings have the quartz sand 5 that silicate solidifies in the melt 6, and a blown fuse indicator 2 is installed in the outside of fusion tube 6.
Operation principle of the present utility model is: this fast acting fuse is installed in the brachium pontis of high-power silicon semiconductor device oil-cooled transformation rectification integrated current rectifier and makes it to be connected with rectifying tube or Thyristors in series, when being reversed, rectifying tube or thyristor puncture when forming certain branch, short-circuit, the short circuit current that flows through fault branch makes the interior melt fusing of fast acting fuse, vaporization, the arcing of series connection, after the energy of electric arc is absorbed by quartz sand, arc extinction, the disjunction fault branch guarantees that voltage transforming rectifier normally moves.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
