Detailed Product Description: | 2) a reasonable choice to protect access to zero (protective ground) and design grounding resistance. Protect access to zero and the cross-sectional area of ??the protective ground conductor must be calculated to determine the choice and short-circuit current with a shell hit check. Its terminals must be well connected, not allowed to have loose, should always check the quality of the connection. Protected electrical equipment grounding resistance value should not exceed 4Ω, electrical equipment such as large capacity, melt fusing current is also large, should be increased in parallel grounding wire grounding section or to sufficiently reduce grounding resistance, increased leakage short-circuit current, the use of high and low voltage power distribution equipment, which is conducive to protective devices. (3) implementation of the equipotential bonding. Leakage protection for single-phase 220V line only provide indirect contact protection, high and low voltage power distribution equipment agents, but there due to mechanical wear and tear, bad, quality is unstable and short-lived factors such action failure cause various problems, not stand alone as a reliable measure of protection, high and low voltage power distribution equipment, so there should implement equipotential bonding in order to effectively eliminate leakage between the metal components of electrical lines or equipment with low potential arcs, sparks generation, namely to eliminate leakage voltage may cause a fire. Equipotential bonding refers to measures to protect access to zero water main bus and buildings, the total gas pipes, HVAC pipes and other metal pipe or wire bonding apparatus, in order to achieve the purpose of the building within a balanced potential, especially for flammable explosive places more of its irreplaceable role. 3.3 to strengthen the electrical design review. Distribution system within the building, the departments concerned should be reviewed when the electrical design strictly in accordance with relevant technology, high and low voltage power distribution equipment notes, for architectural interior renovation should strictly enforce the "interior decoration of buildings for fire protection design" without or minimize the use of flammable combustible materials, especially in the electrical circuit through the fuel, wear a metal pipe or flame-retardant hard plastic pipe protection, because of good plastic insulation properties, it can better prevent leakage, the use of metal pipe When wiring, be sure to prevent insulation from being damaged. Distribution equipment (switches, sockets, distribution boxes, etc.) and electrical equipment and fuel should maintain adequate safe distance, really inseparable, insulated protective measures should be prepared. After the completion of the construction, the electrical installation shall be subject to special inspection institutions qualified and put into use, as far as possible to prevent the occurrence of leakage from the source of fire. 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 greatly improved, on behalf of the common 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.
