摘要： A fluid filled transformer including a tank for containing at least primary and secondary windings, a radiator connected to the tank via top and bottom headers, a fluid disposed in the tank, a fluid circulation flow path including passages through the windings, radiator, headers, and at least a portion of the tank, and at least one diagnostic sensor disposed within the fluid circulation flow path for measuring properties of the fluid. By positioning the sensor within the circulation flow path, measured values are more reliable, accurate, and efficiently sensed.

摘要： A status detection apparatus for electrical equipment includes a plurality of distributed multiparameter sensors in a containment vessel or other fluid filled region of the electrical equipment. The sensors are capable of providing data relating to plural parameters of the fluid simultaneously at different positions in the fluid. The data provided by the sensors can be processed to permit localization of incipient faults or can indicate other operating states when combined with known flow data of the fluid through the electrical equipment. A method for detecting status of electrical equipment includes sensing parameters simultaneously at multiple locations in the fluid and determining operating status based on the sensed parameters.

摘要： An adjustable solenoid having an enclosure containing a winding through which a current is passed. The winding defines an area and a plunger is positioned at one end of the area with a mechanical biasing mechanism for providing a biasing force to the plunger, the mechanical biasing mechanism is secured to the plunger at one end and a support at the other end. A stator having a first threaded portion engaged within a threaded opening of the enclosure causes the stator to travel between a first position and a second position as a rotational force is applied to the stator. The first position is closer to the plunger than the second position, and the stator is in a facially spaced relationship with respect to the plunger and the stator has a second threaded portion for engaging a threaded portion of the support, the second threaded portion of the stator causes the support to travel between a first position and a second position, the second position of the support provides the mechanical biasing mechanism with a greater biasing force than the first position.
