摘要： An automatic control system for providing pneumatic purging protection for a sealed enclosure containing electrical equipment in accordance with the National Fire Protection Association standards. The system supplies a purge gas under a pre-ordained pressure to an enclosure residing in a hazardous location. The system monitors the gas pressure to maintain the pressure within desired limits. In the event that the integrity of the sealed enclosure is disrupted, the control system disables the electrical equipment and executes a rapid-response purge cycle to re-enable the electrical equipment as quickly as possible.

摘要： A molecular sieve moisture absorption device for electrical apparatus containing a dielectric gas includes a box in which the molecular sieve is placed. The box is closed by a plate provided with a valve through which the inside of the box is evacuated. The plate is held in place on a shoulder of the box by the action of pressure difference between the inside and the outside of the box after the inside of the box has been evacuated. A gasket is placed between the plate and the shoulder to ensure that the inside volume of the box is leakproof. The device can be stored independently of the apparatus. When the device is mounted on the apparatus, evacuating the case of the apparatus causes the plate to separate from the box, thereby putting the molecular sieve into contact with the inside volume to be treated of the case.

摘要： A gas-insulated transmission line includes an outer sheath, an inner conductor, insulating supports and an insulating gas. A particle-trapping ring is secured to each insulating support, and it is comprised of a central portion and two tapered end portions. The ends of the particle trapping ring have a smaller diameter than the central portion of the ring, so as to enable the use of the particle trapping ring in a curved transmission line.

摘要： A sealed environment such as in a gas insulated electrical substation is cleaned by introducing a cleansing fluid in vapor form into the environment and condensing the vapor on surfaces within the environment. The condensed fluid is then removed and filtered to extract contaminants such as particulate matter. The cleansing fluid can be continuously introduced or periodically introduced during the cleaning process. By selecting a cleansing fluid with electrical insulating properties and a vaporization temperature lower than the condensation temperature of the gas insulation, electrical apparatus can be cleaned during normal operation of the apparatus.

摘要： A tacky or sticky coating is provided on selected surface areas inside compressed gas-insulated systems to trap conducting and semiconducting particles which, if allowed to remain free, can promote breakdown between metallic parts or electrodes maintained at different potentials, or which may initiate tracking and flashover along insulating surfaces. The initially hard, dry coating is comprised of a binder component and an active component. The binder component is chemically inert to both the insulating gas within the apparatus and a solvent vapor, while the active component is capable of interacting with the solvent vapor to become tacky. The insulating coating, after exposure to the solvent vapor, becomes tacky on the surface to thereon entrap contamination particles, but the addition of the binder component prevents the coating from sagging but instead maintains its spatial position on the selected surface areas.
摘要翻译：在压缩气体绝缘系统内的选定表面区域上提供粘性或粘性涂层，以捕集导电和半导体颗粒，如果允许其保持自由，可以促进保持在不同电位的金属部件或电极之间的破坏，或者可以启动跟踪和沿着绝缘表面闪络。初始硬的干燥涂层由粘合剂组分和活性组分组成。粘合剂组分对设备内的绝缘气体和溶剂蒸汽都是化学惰性的，而活性组分能够与溶剂蒸气相互作用以变粘。在暴露于溶剂蒸气之后，绝缘涂层在表面上变得粘性，从而使污染颗粒被捕获，但是粘合剂组分的添加防止了涂层的下垂，而是保持其在所选择的表面区域上的空间位置。

摘要： This invention relates to compressed-gas-insulated systems. An adherent or sticky coating is provided on selected surface areas inside compressed-gas-insulated systems to trap, or to captivate conducting and non-conducting particles, which if allowed to remain free can promote breakdown metallic parts or electrodes maintained at different potentials, or tracking and flashover along insulating surfaces. Preferably, a coating is provided which is initially hard or solid with adequate mechanical strength so that the system components can be easily handled by workmen during manufacturing and assembly without difficulty, and not at this stage capture unwanted particles. At a later time, following assembly operations, thde surface layer of said coating is rendered adherent, or tacky to trap or to captivate conducting and non-conducting particles. During this stage mechanical means such as vibrations and/or gas flow and/or electric fields may be used to transport unwanted particles to the tacky or captivating areas. Following such captivation, the adherent, or sticky coating may be rendered hard again to trap the unwanted particles permanently. Alternatively, if desired, the coating may be rendered tacky, or captivating again during the life of the equipment to trap unwanted particles generated within or introduced into the system, thus performing a repair or reconditioning of the system. Another alternative is to maintain the coating sticky or tacky during the operating life of the electrical equipment and rendering the surface hard only during repair or maintenance operations when the system is opened and thus subject to handling and thereby large amounts of unwanted particles.
