  • Byproducts of Sulfur Hexafluoride (gaz sf6) Use in the Electric

    Sulfur hexafluoride (SF 6) is a relatively nontoxic gas used in a number of applications for its inert qualities. The dielectric and other physical and chemical properties related to its lack of reactivity have led to the extensive use of SF 6 as an insulating medium in switching equipment (e.g., circuit breakers) by electric utilities. While SF 6

    Sulfur hexafluoride is generally used in present high-voltage circuit breakers at rated voltage higher than 52 kV. Into the 1980s, the pressure necessary to blast the arc was generated mostly by gas heating using arc energy. It is now possible to use low-energy spring-loaded mechanisms to drive high-voltage circuit breakers up to 800 kV.

  • Flow Switches - Intek, Inc.

    Overview of Flow SwitchesWhat Kind of Service Can Our Flow Switches provide?How Do They Work?What Models Are available?How Do I Get One?Flow switches play an important role in regulating the flow rate of fluids through a system. They perform this function by sending a trip signal to another system element (often a pump) that responds by modifying the fluid flow rate as needed. Flow switches are also used for indication of certain process conditions such as flow/no-flow to alert operating personnel by connecting them to indicator lights or audible alarms. Every flow switch has a set point, which is a maximum or minimum flow rate. The set point is typically user-adjustable. When the flow of media reaches the existing set point, the switch prompts the pump (or other mechanism) to turn on or off. The switch can be set to trigger in either low-to-high (e.g., trigger when flow goes from 0 to any flow) or high-to-low (e.g., trigger when flow goes to 0 from any flow value) to match the process requirements. This sequence of events results in the increase or decrease of the flow rate, depending on the requirements of the app...
