The electric arc is actually a kind of plasma. Its characteristic is that the temperature is very good, and the line is very small. If it is continuously generated, it will release a lot of heat, and it may burn, causing serious fires and explosions. The Le Bird's fault arc detector It is specifically designed to detect arc faults. Let's take a look at the causes of arc faults and the invention of fault arc detectors .
The cause of the arc failure
1, insulation carbonization
In many cases, the arc can form a new, different carbonization path. For example, placing two electrodes directly on top of the cable insulation layer and then releasing the high-voltage electricity to the electrodes of the cable can directly cause a certain degree of arcing on the surface of the cable, especially in the environment of pollutants or Leakage currents are generated on wet insulating surfaces, and a long time leads to a deep carbonization path on the insulator surface, resulting in carbonization of the insulation.
2, air ionization
Ionized air can occur both when arcing and burning. Assume that there is a very serious arc fault in the power distribution busbars, and very large amounts of ionized gas will be emitted immediately. All of these ionized gases will fly away from the insulator at a certain distance. If this ionized gas encounters another line at this time, It will easily lead to the decomposition of the air and cause the arc to appear. And combustion also leads to a significant reduction in air dielectric strength, making air more prone to ionization.
3, short circuit
Short circuits usually have two different forms. The first form is a metallic short circuit and the second form is an arc short circuit. The arc short circuit is caused by the temporary contact of the conductors. The metal material next to their initial contact will slowly melt, and the magnetic field force will gradually pull the wire in contact with the place, resulting in the disconnection of the liquid bridge.
The invention of a fault arc detector
If the electric field strength between the two electrodes is very large, then the kinetic energy in the free electrons between the polarities will directly hit the atoms or neutral molecules in the air, which will cause them to free up a very large number of negatively charged liberties. Electrons and positively charged positive ions will continue to strengthen the electric field strength.
In this electric field, negative electrons will constantly hit the cathode, and positive ions will continuously hit the anode. If the energy in the positive ions allows the cathode to dissociate and produce new electron recombination, then the glow discharge will directly transform into an arc discharge, and an arc is formed at this time. The LN6A fault arc detector produced by Beijing LeBiTech Co., Ltd. (Dongguan LeBird Electric Technology Co., Ltd.) is a fire caused by low voltage distribution system (400V), personal electric shock, system failure, L/N line to ground, The L-line is used for monitoring and alarming faults such as N-wires and other fault arcs or electrical equipment. The fault arc detector is invented using this feature. Effective monitoring of protection lines can be effective to prevent fires.

Metal Assembly
Metal assembly refers to the process of joining two or more metal
components to create a single, functional unit. This process can be
accomplished through a variety of methods, including welding, brazing,
soldering, and mechanical fastening.
Welding involves melting the metal components at the joint and fusing
them together. This can be done using various heat sources, including
gas flames, electric arcs, and lasers. Welding is commonly used in the
construction of buildings, bridges, and other large structures.
Brazing and soldering are similar processes that involve melting a
filler material to join the metal components. Brazing uses a
high-temperature filler material, while soldering uses a
lower-temperature material. These processes are often used in the
manufacture of electronics and plumbing components.
Mechanical fastening involves using bolts, screws, or other fasteners to
hold the metal components together. This method is commonly used in the
assembly of machinery and vehicles.
Metal assembly is a critical process in many industries, including
manufacturing, construction, and transportation. It requires skilled
technicians and specialized equipment to ensure that the components are
joined correctly and that the final product meets the required
specifications.
