Description

A kind of surge protective device suitable for electrical terminations

Technical field

The utility model belongs to technical field of electric automation, more particularly to a kind of wave suitable for electrical terminations Gush protection device.

Background technology

Surge Protector (surge protection device, surge protector) is also known as arrester, and abbreviation SPD is applicable In exchange 50/60HZ, the electric power system (or communication system) of rated voltage to 380V, to indirect thunder and lightning and direct effects of lightning Or the surge of other instantaneous overvoltages is protected, it is adaptable to home dwelling, the tertiary industry and industrial circle surge protection will Ask, with relative phase, relatively, relative center line, the center line protected mode such as over the ground and combinations thereof.

Surge Protector is widely used a kind of power transmission and transformation primary equipment in power system, is important in power system Overvoltage protection.Because Surge Protector has good nonlinear resistance property, so being not have inside Surge Protector There is gap.Just because of very close to each other, the effect of Operation of Electric Systems voltage is born for a long time in normally operation middle valve plate, and The influence of the factor such as internal wetted or overheat, easily causes the deterioration of valve block nonlinear resistance property.The main table of this deterioration It is now the increase of the current in resistance property under normal voltage, the increasing of current in resistance property can cause the increase of caloric value, then cause surge The rising of protector internal temperature, the rising of temperature can then accelerate the aging of valve block, thus formed it is pernicious follow bad, finally result in and keep away Thunder device is damaged due to overheat, and the blast of Surge Protector is possibly even caused when serious, then causes large area blackout.

Therefore, research and develop reliable, advanced, easily surge protective device, be promote electrical terminations safety, The basis of steady operation and premise.
