    摘要: The design of electrical switches that operate under load (with current flowing) requires replacement of the electrical contact after erosion and wear experienced by arcing and raised temperatures reduce functionality below acceptable limits.A quantity of trace element or compound is implanted at a depth representative of the point at which wear or erosion requires contact replacement. When exposed by wear or erosion, the quantity of the trace element is released into the oil or other medium surrounding the contact, providing an indication of excessive wear.

    摘要: A system for determining when an electrical contact or other component reaches a predetermined temperature. In operation, a trace material is dispersed into a surrounding environment (e.g., head space within a compartment above insulating oil), where the trace material is detected. A barrier may be ruptured or broken by temperature-induced gas pressure, or pierced by a spring-loaded member that is located within the same section that contains the trace material, and devices may be provided for moving the trace material through the foil barrier as the barrier is ruptured. The barrier may be opened solely by internal gas pressure. According to another embodiment, improved fail-safe operation may be achieved by providing a spring-loaded member and configuring the barrier to be ruptured by the pressure of the detectable gas material before the barrier is ruptured by the spring-loaded member.

    摘要: A reversing switch for a tap changer of a transformer is provided. The reversing switch includes first and second contact structures for connection to a winding of the transformer and a mounting structure for connection to a neutral terminal of the transformer. A bus bar connects a third contact structure to the mounting structure. A movable contact arm is secured to a rotatable post. The contact arm includes a contact assembly mounted to an arm. The contact assembly has one or more outward contacts and one or more inward contacts. The one or more inward contacts engage the third contact structure and the one or more outward contacts selectively engage the first contact structure or the second contact structure. The first and second contact structures and the mounting structure are located at about the same radial distance from the post, while the third contact structure is located closer to the post.

    摘要: A burst temperature indicator system for determining when an electrical contact or other component reaches a predetermined temperature. In operation, a trace material may disperse into a surrounding environment, and be detected, when the electrical component reaches a predetermined threshold temperature. One or more foil barriers may be ruptured or broken by temperature-induced gas pressure. According to another aspect of this disclosure, a rupture disk may be burst at a predetermined temperature to generate, or enable emission of, a light signal. According to another aspect, a rupture disk device acts as, or is associated with, an engine to drive one or more electro-mechanical and/or acoustic devices to signal the occurrence of a predetermined temperature.

    摘要: Methods and systems for determining when an electrical contact reaches the maximum allowable temperature. The methods and systems include defining a plurality of temperature indicators installed in at least one surface of the electrical contact to indicate at least one specific temperature; providing a trace material within the at least one temperature indicator; allowing the electrical contact to reach the at least one specific temperature at which the at least one temperature indicator is designed to activate in or on the at least one surface of the electrical contact; causing the trace material to disperse from the at least one temperature indicator into a surrounding environment; and monitoring the surrounding environment to determine when a predetermined quantity of the trace material has dispersed into the surrounding environment, thereby indicating that the electrical contact has reached the at least one specific temperature at which the at least one temperature indicator is designed to activate.
