disconnect switch การใช้

• In a common design, incoming lines have a disconnect switch and a circuit breaker.
• A disconnect switch is used to provide isolation, since it cannot interrupt load current.
• Metal-enclosed safety disconnect switches are used for isolation of circuits in industrial power distribution.
• The output of the transformers is routed to track catenary via 12 kV circuit breakers and air disconnect switches.
• The de-icing disconnect switches are opened, and the DCU then releases the power line back to the AC network.
• In an electric power system, "'switchgear "'is the combination of electrical disconnect switches, faults downstream.
• The specialty of "'Kraus & Naimer "'are load and disconnect switches as well as modular power distribution systems.
• Then, a line de-icing circuit is created by a set of disconnect switches controlled by the DCU which sends all of the commands to the de-icing converter.
• Square D also made disconnect switches, both fused, and unfused, as well as Heating Air Conditioning and Refrigeration ( HACR ) rated switch boxes that held an HACR breaker for use as a disconnect.
• These meters are fully electronic and smart, with integrated bi-directional communications, advanced power measurement and management capabilities, an integrated, software-controllable disconnect switch, and an all solid-state design.
• The primary way to prevent the release of hazardous energy during service and maintenance activities is by using energy-isolating devices such as manually operated circuit breakers, disconnect switches, and line valves and safety blocks.
• PEARL is focused on developing ethical business practices and technical standards related to inspecting, testing, and reconditioning circuit breakers, transformer, motor controls, switchgear, disconnect switches, protective relays, bus duct, motor starters and other electrical equipment and apparatus used in the electrical distribution systems of commercial, industrial, and utility facilities.
• With the advent of more worldwide installations and the requirements laid down in many country s national wiring publications for the use of DC switches in PV installations, TRUE DC Solar Isolators must also be assessed and tested under the latest UL standard UL508I which has been specifically written to cover the use of  Manual Disconnect Switches intended for use in Photovoltaic Systems.
• A mechanical device that physically prevents the transmission or release of energy, including but not limited to the following : a manually operated electrical circuit breaker; a disconnect switch; a manually operated switch by which the conductors of a circuit can be disconnected from all ungrounded supply conductors, and in addition, no pole can be operated independently; a line valve; a block; and any similar device used to block or isolate energy.
