Cathodic protection Pipeline Project SSD solid state to a coupler

1, the product uses the pipeline through the high-voltage lines, electrified railways, power plants and other sources of interference, susceptible to interference and stray current corrosion; even some high voltage, high current will damage the cathodic protection potentiostat, leading to the cathodic protection The system can not properly put into operation, thus losing the pipeline cathodic protection, impact to the tube life. Solid State decoupling can effectively reduce the DC, AC stray current effects on buried pipelines, pipeline cathodic protection system to enhance stability and extend the life of the pipeline. 2 Features I produced the solid-state decoupling technology uses advanced solid-state, non-metallic shell, the internal use of pure imported components, to ensure that the performance of the product. As DC isolation and AC-coupled devices, not only to prevent the cathodic protection current reaches a predetermined threshold voltage, while conducting alternating current induction. When the voltage exceeds the threshold voltage trying coupler immediately switch to short-circuit mode to provide over-voltage protection; when the overvoltage past, and automatically switch back to DC isolation mode, this mode of operation can be carried out numerous times. Conventional rated isolation voltage range: -2V ~ + 2V, I also can be customized according to the needs of users. 3, performance parameters No. Item Parameter 1 Rated isolation voltage (leakage current ≤1mA) -2V (at -2V / + 2V condition) / + 2V 2 Rated lightning impulse current capacity (4 / 10μs) 100kA 3 steady alternating current ≤45A 4 DC leakage current ≤ 1mA 5 fault current (AC-rms / frequency / 30 cycle) ≥3500A 6 Operating temperature -45 ℃ ~ + 60 ℃ 7 Protection class IP65 4, Packing List solid state to a stationary bracket coupler one pair proof junction box 1-connected terminal 2 heat shrink tubing 2 stainless steel bolts 6 certificate, manual 1
