    Abstract: Long thermal paths and the resulting slow response times in sealed and electrically insulated thermal sensors may be substantially reduced by insulating and sealing the sensor (26) by a method which includes the steps of providing (30) an electrostatic fluidized bed of electrically insulating resin; locating (34) the sensor (26) at the bed; coating (36) the sensor (26); removing (38) the sensor from proximity to the bed; and curing (40) to the resin to form a uniform, thin coating encapsulating the sensor (26).

    Abstract: A high temperature electrical insulation system is provided by forming a winding in an electrical device from a conductor that is pre-coated with a first layer of at least partially cured inorganic material. A second layer of inorganic material is applied, either during or just prior to forming the winding, over the first layer in order to seal any cracks in the first layer. The resultant electrical insulative coating is cured following the forming process, essentially at room temperature. The insulation system provided is thus totally inorganic, and its manufacture does not require the use of organics, or heating to high temperatures to cure the coating or to cause pyrolysis and/or volatilization of organic elements, as did prior electrical insulation systems. Furthermore, because no organics are utilized in either the manufacture or operation of the insulation system, there is no residual carbon in the resultant coating. The problem of reduced dielectric strength - caused by residual carbon - which plagued some prior attempts to develop polymer based high temperature insulation systems, is thus eliminated. By utilizing only inorganic materials, the insulation system provided is capable of operating satisfactorily for extended periods of time at temperatures in excess of 500 DEG F.

    Abstract translation: 通过从预先涂覆有第一层至少部分固化的无机材料的导体在电气装置中形成绕组来提供高温电绝缘系统。 在形成绕组之前或之前，在第一层上施加第二层无机材料，以密封第一层中的任何裂纹。 所得的电绝缘涂层在形成过程之后固化，基本上在室温下固化。 因此，所提供的绝缘系统是完全无机的，并且其制造不需要使用有机物，或者加热到高温以固化涂层或者引起有机元素的热解和/或挥发，如现有的电绝缘系统。 此外，由于在绝缘系统的制造或操作中没有使用有机物，所以在所得的涂层中不存在残留的碳。 因此消除了由残留碳引起的降低的介电强度的问题，其困扰了先前尝试开发基于聚合物的高温绝缘系统。 通过仅利用无机材料，所提供的绝缘系统能够在超过500°F的温度下延长工作时间令人满意地工作。
