A new and innovative way to store methane could speed the development of natural gas powered cars that don't require the high pressures or cold temperatures of today's compressed or liquefied natural gas
Abroad CIRCUIT BREAKER gas Gas tank Prospect
2019/9/18The circuit breaker in a gas insulated system is metal clad and utilises SF6 gas, both for insulation and fault interruption. The SF6 gas pressure in a circuit breaker is around 0.65 MPa . The circuit breaker is directly connected to either current transformers or the isolators in gas.
40 5kv sf6 n2 transformer
40.5kV Current Transformer (oil immersed)CT Product Details： Current transformer (CT) is used for measurement of electric currents. When current in a circuit is too high to directly apply to measuring instruments, a current transformer produces a reduced current accurately proportional to the current in the circuit, which can be conveniently connected to measuring and recording instruments.

OverviewA circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit. Its basic function is to interrupt current flow after a fault is detected. Unlike a fuse, which operates once and then must be replaced, a circuit breaker can be reset (either manually or automatically) to resume normal operation. Circuit breakers are made in varying sizes, from small devices that protect low current circuits or individual household appliance, up to large switchgear designed to protect high voltage circuits feeding an entire city. The generic function of a circuit breaker, or fuse, as an automatic means of removing power from a faulty system is often abbreviated as OCPD (Over Current Protection Device).

medium voltage Sulfur Hexafluoride National standard Acquisition
Sulfur Hexafluoride (SF6) is a non toxic, inert, insulating and cooling gas of high dielectric strength and thermal stability. It is particularly suitable for application in both high voltage and medium high voltage power circuit breakers as well as in high voltage cables, transformers, transducers, particle and electron accelerators, X ray equipment and UHF transmission systems.
middle voltage track
middle voltage track2015/2/11The meter should be set to read millivolts. Then slowly "walk" the voltmeter leads down the track. The reading should be very low, in the millivolt range. The voltage should slowly decrease as you approach the short. Once the short is reached and you go beyond the short, the rate at which the voltage is decreasing will change.
