A low-temperature fluid flow electrostatic accumulation strength measurement experimental device and method, including a transmission
pipe section and a test
pipe section; the outside of the test
pipe section is wrapped with a bare
copper wire, and the test pipe section is provided with a
copper mesh shield and a stainless
steel square cavity shield; the inlet of the stainless
steel square cavity shield is connected with the outlet of a first low-temperature
ball valve and a low-temperature orifice flowmeter, the inlet of the low-temperature orifice flowmeter is connected with a first low-temperature stop valve and a transmission pipeline, and the outlet of the stainless
steel square cavity shield is connected with a second low-temperature stop valve; the inlet of the test pipe section is connected with the outlet of a second low-temperature
ball valve and a low-temperature orifice flowmeter; silver electrodes are arranged at the inlet and the outlet of the test pipe section; the outlet pipeline of the test pipe section extends into the inner container of a Faraday cylinder, and the
BNC connector of the Faraday cylinder, the silver electrodes, the bare
copper wire, the stainless steel
square cavity shield, the copper mesh shield and an electrostatic meter are connected; the application studies the electrostatic accumulation
current strength generated by the low-temperature working medium flowing in the pipe, and provides support for the electrostatic safety of a low-temperature
propellant pipeline
transmission system.
