Outdoor alternating current power supply lightening protector

Abstract

The invention discloses an outdoor alternating current power supply lightening protector. Currently, the known alternating current power supply lightening protector is too low in waterproof and dustproof level and only can be used in indoor environment. The invention is composed of a power supply output joint, a metal shell, a general grounding wire, an internal grounding wire a, an indoor alternating current lightening protector, an internal connection L, an internal connection N, an internal grounding wire b, a power supply input connection distribution terminal and an insulating strip. Theinvention has the positive effects that the invention is provided with the metal shell with favourable waterproof and dustproof performances, the outdoor alternating current power supply lightening protector formed by combining selection of qualified indoor alternating current lightening protector can transform a fourth class overvoltage transient 6kV direct current input into 2.5kV second class direct current output protection, so as to realize lightening protection function. The lightening protector is reasonable and compact in structure, in volume is small, internal connecting wire is short, and operation is stable and reliable.

Description

technical field [0001] The invention relates to a safe electrical equipment, in particular to a lightning protector structure. Background technique [0002] At present, the main measures of known AC power surge protectors are: isolation, clamping, voltage equalization, filtering, shielding, overvoltage and overcurrent protection and other methods to eliminate lightning overvoltage, overcurrent and lightning electromagnetic pulses at the periphery of the equipment, to achieve The purpose of protecting various types of equipment. Due to the internal limitations of the internal discharge and arc extinguishing devices, the waterproof and dustproof level is too low, and generally can only be used in indoor environments, and cannot be used in harsh outdoor environments with rain, dust, and air pollutants. use. At the same time, its input and output wiring methods are also very limited. Contents of the invention [0003] In order to overcome the deficiencies of the AC power su...
