This invention provides a safety magnetic field critical point detection device and a method for hierarchical detection of magnetic field distribution. The safety magnetic field critical point detection device includes a base, a pile, a first detection component, a second detection component, and a control component. A walking component is located at the bottom of the base. The pile is located on the upper side of the base and has a warning component. The first detection component is connected to the pile and is used to detect the field strength at the location of the pile. The second detection component is connected to the pile and is adapted to rotate around the pile to detect the field strength around the pile. The control component is electrically connected to the walking component, the first detection component, and the second detection component, and internally stores the critical point field strength. The control component is adapted to control the walking component to move the pile to the critical point field strength based on the field strength detected by the first and second detection components. The hierarchical detection method of magnetic field distribution, based on the above-mentioned safety magnetic field critical point detection device, can realize hierarchical visualization of magnetic field distribution.

There is disclosed a method of vectoring a rocket propulsion system producing a partly ionized exhaust jet along a longitudinal jet axis and through a nozzle. One or more pairs of electrodes may straddle the exhaust jet inside the nozzle or at a nozzle exit. A high-voltage DC supply may energize one or more of the electrode pairs with a strong electric field. A field intensity of the electric field may be scaled by the DC supply to proportionately deflect the exhaust jet away the longitudinal axis by a desired vectoring angle. The particular pair voltages sent to each pair of electrodes by the DC supply may be weighted for establishing a desired azimuth for the deflection. The strong electric field may laterally accelerate positively charged particles in the exhaust jet toward a negatively charged side of the one or more electrode pairs, thereby achieving the desired deflection and azimuth.

The application discloses a quick-mounting shielding ball for a converter station fitting, which comprises a mounting seat, a shielding shell fixedly installed at the upper end of the mounting seat, a lower shell, an adjusting shell and an upper shell, wherein the outer surfaces of the lower shell, the adjusting shell and the upper shell are smoothly connected, a driving bevel gear is fixedly installed on the inner wall of the adjusting shell, a driven bevel gear is uniformly rotationally assembled on the inner wall of the upper shell, an adjusting structure is fixedly installed on the inner end of the driven bevel gear, a self-locking structure is assembled on the output end of the adjusting structure, a sliding rail structure is uniformly fixedly installed on the inner wall of the lower shell, and a connecting structure is used for connecting the fitting and the shielding shell. In the application, the outer surface of the shielding shell forms a smooth spherical surface without sharp edges and corners. When the spherical surface is in equipotential with the high-voltage fitting through the internal connecting structure, the smooth and continuous surface can maximize the homogenization of the electric field distribution on the surface, effectively reduce the maximum electric field intensity on the surface to below the critical corona onset field intensity of air, thereby inhibiting the generation of corona, and the shielding effect is better.

The invention relates to a Halbach array-based magnetic field enhanced water electrolysis hydrogen production method and system, and belongs to the technical field of water electrolysis hydrogen production. The method solves the technical problems that bubbles are accumulated due to stress concentration of a square alkaline electrolytic cell, and the electrolytic efficiency is limited due to the fact that the number of magnets is large, magnetic field intensity is weak and distribution is uneven in a traditional magnetic field auxiliary technology. According to the technical scheme, a high-field-intensity uniform single-direction magnetic field is constructed by integrating a Halbach permanent magnet array in an end plate and a bipolar plate of an electrolytic bath, and bubbles are promoted to be stripped from the surface of an electrode by utilizing a Lorentz force and a magnetohydrodynamic effect generated by interaction of the magnetic field and electrolytic current; and meanwhile, the corrosion resistance is improved by combining a nonmetal electrolytic cell structure such as a glass fiber reinforced epoxy resin pole frame and a graphite lining. The method has the beneficial effects that the bubble desorption capacity is remarkably enhanced, the mass transfer process is improved, the hydrogen evolution and oxygen evolution reaction rate is increased, and therefore the electrolysis efficiency is improved.
