Embodiment Construction

[0033]The technical solution of the present invention is to use the mica ceramic ingredients with good electrical insulation properties to firmly fix the metal inserts in the ceramic insulator by hot pressing technology to form a mica ceramic insulator for high-speed electric locomotives, so this product It is mainly composed of two parts: an electrically insulating ceramic body and a metal connecting pole, that is, a metal insert. Among them, the insulating ceramic body is mainly composed of synthetic mica powder and electrical glass powder, while the metal connecting pole can be designed according to the needs of the installation environment, and the material can be selected from various metal materials such as stainless steel or ordinary steel. The metal insert includes two independent poles, upper and lower. The two poles are divided into outer and inner ends. The inner end is embedded in insulating ceramics. The outer end of the lower pole is installed through external or ...

Abstract

The invention discloses a mica ceramic insulator for a novel high-speed power car and a manufacturing method thereof. The mica ceramic insulator mainly consists of a mica ceramic body and a metal connection terminal embedding piece, wherein the metal embedding piece comprises an upper and a lower independent terminals, the terminal is provided with an outer end and an inner end, the inner end is embedded inside the mica ceramic insulation body, one of the outer ends is installed on a fixed object, and the other end is connected with a conductive body. The mica ceramic insulator is produced ina hot-pressing method, i.e. the ingredients are pre-burned for 1 to 10 hours at the temperature of 750 to 1000 DEG C and are then pelletized into ceramic powder with the granularity of 10 to 100 meshes, the ceramic powder then is cooled to be a green body for hot-pressing, the mica ceramics and the metal terminal embedding piece are pressed and formed in a heated mould at a high temperature through a hot-press molding technology, and then the mica ceramic insulator product is prepared through the annealing and the coating treatment. The produced mica ceramic insulator has good insulation performance, good mechanical performance and high temperature resistance, and can completely satisfy the application requirement of the high-speed large-power AC power car.

Description

technical field [0001] The invention relates to an insulator for an electric locomotive and a manufacturing method thereof, in particular to a mica ceramic insulator for a high-speed electric locomotive and a manufacturing method thereof. Background technique [0002] With the increasing demand for railway transportation, in recent years, China has introduced foreign advanced high-speed electric locomotive vehicle manufacturing technology. Therefore, the absorption and digestion of foreign technologies and the gradual realization of localization of locomotive parts have become a top priority. [0003] Insulators are important components of power systems. Most of the imported high-speed electric locomotives are driven by high-power AC motors, which is different from the current domestic mainstream electric locomotives driven by DC motors. In the existing electric locomotives driven by DC motors, insulators made of organic polymer composite materials such as rubber and resin...
