Abstract

FIELD: permanent way; electric heating devices. SUBSTANCE: heater has sheet steel body embracing both, web and foot of rail. Body houses thin metal boxes with heating cable. Outer walls of heater are insulated by thermal shield which cuts down external radiation losses. Each heater is designed for operation on supply with currents up to 5 A at 350 - 400 W. EFFECT: enhanced operation of switch. 2 dwg

Description

Изобретение относится к электронагревательным устройствам, работающим на постоянном и переменном токе, предназначенным для растапливания и очистки в зимний период от снега и льда железнодорожных стрелочных переводов. The invention relates to electric devices operating on direct and alternating current, designed for melting and cleaning in winter from snow and ice railroad switches.

Целью изобретения является повышение КПД электрообогревателя и снижение времени, затрачиваемого на очистку стрелок. The aim of the invention is to increase the efficiency of the electric heater and reduce the time spent on cleaning arrows.

На фиг. 1 показана форма корпуса обогревателя; на фиг. 2 - обогреватель в разрезе, где обозначены: 1 - металлический корпус-основание, 2 - нагревательный элемент для шейки рельса, 3 - нагревательный элемент для подошвы рельса, 4 - витки нагревательного кабеля ПНСФЭ, 5 - термоизоляция. От корпуса 1 нагревательные элементы 2, 3 изолированы термопрокладками из асбеста. Размеры обогревателя 260 х х140 х 130 мм. In FIG. 1 shows the shape of a heater body; in FIG. 2 - sectional heater, where are indicated: 1 - a metal body-base, 2 - a heating element for the rail neck, 3 - a heating element for the rail sole, 4 - turns of the PNSFE heating cable, 5 - thermal insulation. From the housing 1, the heating elements 2, 3 are insulated with thermal pads made of asbestos. The dimensions of the heater are 260 x x 140 x 130 mm.

В обогревателе основой служит металлический корпус, в котором расположены нагреватели шейки и подошвы рельса, т. е. одновременно обогревается и шейка и подошва рельса. Максимальная мощность обогревателя 400 Вт, максимальный ток 5 А. (56) Заявка ФРГ N 1277290, кл. E 01 B 7/24, опублик. 1968. In the heater, the base is a metal case in which the neck and sole heaters are located, i.e., the neck and sole of the rail are simultaneously heated. The maximum heater power is 400 W, the maximum current is 5 A. (56) Application for Germany N 1277290, class. E 01 B 7/24, published. 1968.
