Detailed Product Description: | Digital technology (Digital Technology) refers to the use of certain kinds of information devices, including, maps, text, sound, image, etc., into computer recognizable binary numbers for computing, processing, "0" and "1", storage, transmission, distribution, reduction technology. Often referred to as digital technology. Digital technology as the basis, LSI is mainly composed of digital equipment, the analog signal is measured for A / D conversion, transmission, processing, storage and signal display are digital signal to test speed accuracy is also greatly improved, high and low voltage power distribution, often on behalf of instrument constant temperature and humidity box, temperature sensors. Digital intelligent instrument, the foundation of individual instruments and virtual instrument, is the premise of computer technology into the measuring instrument. Widely used in electronic digital computer numerical control technology, communication equipment, digital instrumentation, etc., such as a human first electronic digital computer ENIAC, Aisida microscope, stereo microscope, X-ray machines. Many factors caused by leakage, high and low voltage power distribution equipment vendors, to sum up, there are the following: (1) low-voltage distribution system installed multiple non-electrical professionals, uneven quality, quality is difficult to guarantee, as follows: damp or corrosive acid environments, wire for surface, equipment protection without making direct installation: wiring, knife, pliers, hammers and other damage insulation; wire connectors and connection quality insulation package rolling quality does not meet the requirements, etc. abnormal phenomena: (2) electrical lines or equipment negligent inspection, because of an overload or a longer useful life and other reasons insulation deterioration; (3) use of fake, counterfeit electrical products; (4) external factors: water immersion, squeezing , rat-bite and so on. 2, leakage caused by fire reasons (1) leakage current cause a fire. Under normal circumstances leakage fault point contact can not real, like pick a non-ground, resulting in a larger contact resistance, making it difficult overcurrent protection operation, and it will generate an arc at the point of failure. According to the survey, only 0.5A current arc temperature can exceed 2000 ℃ or more, enough to ignite all combustible materials. (2) protection of the zero line or the protection of ground connection at the terminals is not real, cause a fire. Phase line and the zero line terminal connection is not real, the device is not working properly, you can discover process, and to protect the terminals connected to the zero line or the ground is not solid, high and low voltage power distribution box, resistance is too large, the device work as usual, fault the point is not easily found. Once the leakage, due to the failure point is too loose or corroded fittings, etc., appear high impedance, resulting in local overheating, sell high and low voltage power distribution equipment, connection terminals produce heat or electric arc can ignite surrounding combustible materials, or burn the electric sockets, switches and so on, igniting the wood base, which is the more common form of leakage fire. In July 2000, Hangzhou a hotel switchboard fire that is one case, before the fire, the hotel is closing, the load at the bottom. When the fire broke out, lighting, electricity is still normal. The investigation of the total distribution box air switch severe charring, protection of the zero line terminal molten metal concave mark, consistent with the leakage problem.
