Description
(5А) УСТРОЙСТВО дл ИЗМЕРЕНИЯ ВЕЛИЧИНЫ ИЗНОСА КОНТАКТНОГО ПРОВОДА(5A) DEVICE FOR MEASURING THE VALUE OF WEAR OF A CONTACT WIRE
1one
Изобретение относитс к испытатель ной технике, а именно, к измерению износа материала.The invention relates to a test technique, namely, to measure the wear of a material.
Наиболее близким к изобретению по технической сущности и достигаемому эффекту вл етс устройство дл измерени величины износа контактного провода, содержащее источник питани , св занные с ним измерительный элемент выполненный в виде гибкой пластины, покрытой слоем изол ции со стороны контактного провода и регистрирующий блок lJ.The closest to the invention in technical essence and the achieved effect is a device for measuring the amount of wear of a contact wire containing a power source, a measuring element connected to it made in the form of a flexible plate covered with an insulation layer on the side of the contact wire and a recording unit lJ.
Однако из-за неравномерного износа измерительного элемента емкость между проводом и элементом по длине элемента будет различной.However, due to uneven wear of the measuring element, the capacitance between the wire and the element along the element will be different.
Цель изобретени - повышение точности .The purpose of the invention is to improve accuracy.
Указанна цель достигаетс тем, что в устройстве дл измерени величины износа контактного провода, содержащем источник питани , св занные с ним измерительный элемент иThis goal is achieved by the fact that in a device for measuring the amount of wear of a contact wire containing a power source, a measuring element associated with it and
регистрирующий блок, измерительный элемент выполнен в виде .параллельно расположенных и изолиров анных друг от друга электропроводных гребенок с зубь ми из упругого материала,сдвинутых относит льно друг друга на рассто ние , не.,превышающее шага зубьев, и резисторов, электрически св зывающих между собой гребенки.the registering unit, the measuring element are made in the form of electrically conductive combs arranged in parallel and isolated from each other with teeth made of an elastic material that are offset to each other at a distance not exceeding the pitch of the teeth and resistors electrically interconnected combs.
На чертеже показана схема устрой10 ства.The drawing shows a device diagram.
Устройство содержит источник 1 питани , св занный с ним измерительный элемент, выполненный в виде па15 раллельно расположенных и изолированных друг от друга электропроводных гребенок 2 с зубь ми 3 из упругого материала, сдвинутых относительно друг друга на рассто ние, не превы20 шающее шага зубьев, регистрирующий блок k, св занный с источником 1 питани и резисторы 3, св зывающие между собой гребенки 2.The device contains a power source 1, a measuring element associated with it, made in the form of electrically conductive combs 2 parallel to and isolated from each other with teeth 3 of elastic material that are displaced relative to each other at a distance not exceeding 20 tooth pitch, registering block k associated with power supply 1 and resistors 3 interconnecting the combs 2.
