SURGE ANTI-INTERFERENCE OF WEAK ELECTRICITY EQUIPMENT IN THE TRANSFORMER SUBSTATION

Combined with the harm caused by the interference that electricity surge does to the weak electricity equipment, the essay gives a specific analysis of the interference of the electricity surge. Then, it puts forward several protection measures and circuits of hardware design which canrestrain the electricity surge. At last, it comes to the protection products of the electricity surge, inside and outside the country and demonstrates an introduction and prospect of the situation, level, and direction of its development. In a word, the measures have great practical value of use: they can not only improve the security and reliability of functioning of the weak electricity equipment, but also prevent accidents from occurring.
