1one

Изобретение относитс к электротехнической промышленности, преимущественно дл производства электрических источников света, например ламп накаливани .The invention relates to the electrical industry, primarily for the manufacture of electric light sources, such as incandescent lamps.

Известны лампы накаливани , защита электрической цепи которых осуществлена индивидуальным плавким предохранителем в виде ферроникелевого звена одного из выводов Г Недостатком указанных ламп вл етс то, что плавкий предохранитель не способен защитить от разрушени тело накала при возникновении в лампе дугового разр да и его невозможно реставрировать.Incandescent lamps are known, whose electric circuit is protected by an individual fuse in the form of a ferronickel link in one of the conclusions.

Наиболее близкой к предлагаемой по технической сущности вл етс лампа накаливани , защита электрической цепи которой осуществлена путем введени в цоколевочную мастику ,гранул галоидных соединений некоторых металлов, например СаР2,Closest to the proposed technical entity is an incandescent lamp, the protection of the electrical circuit of which is carried out by introducing into the base mastic of granules halides of certain metals, for example CaP2,

Claims

10 in an incandescent lamp containing a flask with a base attached to it, a filament body installed in it with the help of internal links of current leads, the external links of which are connected to the corresponding contacts of the base, and means for protecting the body from destruction, to internal links of leads 20 pieces of molybdenum wire are attached, the free ends of which form a discharge gap, one of the two external links is made with a smaller one (section. 393 is installed inside a sleeve of thermally insulating material; In the hole of one of the contacts is a socle, and it is connected with the specified contact by solder from a low-melting material, and the length of the specified discharge gap is 1.5-2 times less than the distance between the sections of the filament body. The lamp contains pieces of molybdenum wire 1, forming a discharge gap a, connected to the internal links m 2 of the current-carrying leads, having external links 3 and 4, from which the external link has a reduced cross section. The external terminal C is installed inside the sleeve 5 of thermal insulation material that is located in the contact hole 6 of the base and is connected to it by solder 7, which acts as a fusible fuse. Since the distance between the cutters of the molybdenum wire 1 forming the discharge gap a is chosen so that the potential gradient is 1.5–2.5 times higher than between the sections (section of the heat body) Only in the discharge gap, the current flowing in the lamp electric circuit increases dramatically, the external link 4 of the reduced cross section is heated more, and since its direct contact with contact 6 is prevented by the socket 5 of the thermal insulation material and connection Between them is made with solder 7 playing the role of a fuse, then the solder 7 melts and breaks the lamp circuit, thereby terminating the arc discharge in it. The lamp body of the lamp is suspended outside the zone of action of the arc discharge and it is enough to reuse the lamp connect terminal k with contact 6 of the socket with solder 7. The proposed lamp has the following advantages as compared with the known ones: when an arc discharge occurs in the body lamp, the heat does not break; fuse is subject to restoration; the material consumption of the external link link is reduced by reducing its cross section. The use of the proposed lamp makes it possible to re-use it after the occurrence of an arc discharge, which provides savings in the national economy. The invention of an incandescent lamp containing a flask with a base attached to it, a glowing body installed therein by means of internal links of current-carrying leads, the external links of which are connected to the corresponding contacts of the basement, and means for protecting the body from destruction By the fact that, in order to increase reliability and service life, segments of molybdenum wire are attached to internal links, the free ends of which form a discharge gap, one of the two external links is made with a smaller cross section m, installed inside a sleeve of thermally insulating material located in the hole of one of the contacts of the socket, and connected to the specified contact with solder of a low-melting material, the length of the specified discharge gap 1.5-2 times smaller than the distance between sections of the filament body.
