Embodiment Construction

[0010] To promote an understanding of the principles of the invention, reference will now be made to the embodiments illustrated in the drawings, and specific language will be used to describe the principles of the invention. It should be understood, however, that no limitation of the scope of the invention is intended thereby. Any changes and further modifications in the described embodiments, and any further applications of the principles of the invention described herein are considered to be as would normally occur to one skilled in the art to which the invention pertains.

[0011] refer to figure 1 and figure 2 , schematically illustrates some aspects of a non-limiting example of a sulfur hexafluoride (SF6) insulated circuit breaker system 10 according to an embodiment of the present invention. In one form, the circuit breaker system 10 employs a SF6 dielectric gas blowing system to force pressurized SF6 between the circuit breaker contacts during circuit interruption (...

Abstract

A circuit breaker system with an SF6 tank and an SF6 heating system, the SF6 tank having walls. The SF6 heating system includes a heater set outside the tank and a radiator set on the wall inside the SF6 tank. The radiator is thermally coupled to the heater through the wall. The heating system is configured to conduct heat from the heater through the wall to the radiator. The radiator is constructed to radiate heat to the SF6 in the tank. A circuit breaker system with an SF6 tank and a particle trap, the SF6 tank having walls. The particle trap has a spar extending radially inwardly from the wall and wings extending outwardly from each side of the spar. Each wing is spaced apart from the wall and creates an area free of electric fields at the bottom of the tank adjacent the spar.

Description

technical field [0001] The present application relates generally to circuit breaker systems, and more particularly, but not exclusively, to circuit breaker systems having a combination heating radiator and particulate trap. Background technique [0002] Various types of electrical systems, such as circuit breaker systems, remain an area of ​​interest. Some existing systems have various disadvantages, deficiencies, and inadequacies with respect to particular applications. For example, in some circuit breaker systems, improvements in sulfur hexafluoride (SF6) heating and particle capture can be made. Therefore, further contributions in this technical field are still required. Contents of the invention [0003] One embodiment of the present invention is a unique SF6 insulated circuit breaker system with heated radiators. Another embodiment is a unique SF6 insulated circuit breaker system with particle trap. Another embodiment is a unique SF6 insulated circuit breaker syst...
