Description
Technical Field
The utility model relates to a zinc oxide lightning rod technical field specifically is an organic load overcoat zinc oxide lightning rod convenient to dismantle and change.
Background
The zinc oxide arrester is an arrester with good protection performance. The current flowing through the lightning arrester is extremely small (microampere or milliampere) at normal working voltage by utilizing the good nonlinear volt-ampere characteristic of the zinc oxide; when overvoltage acts, the resistance drops sharply, and the energy of the overvoltage is released, so that the protection effect is achieved. The difference between the arrester and the traditional arrester is that it has no discharge gap, and utilizes the nonlinear characteristic of zinc oxide to play the role of current leakage and cut-off, and the zinc oxide arrester is a new type arrester developed in the seventies, and it is mainly formed from zinc oxide piezoresistors, and every piezoresistor has a certain switching voltage (called voltage-dependent voltage) when it is made, and under the normal working voltage (i.e. less than voltage-dependent voltage), its piezoresistor value is very large, and is equivalent to insulation state, but under the action of impulse voltage (greater than voltage-dependent voltage), its piezoresistor is low-value breakdown, and is equivalent to short-circuit state. However, the varistor can recover the insulation state after being struck; when the voltage higher than the voltage-sensitive voltage is removed, it recovers the high-impedance state. Therefore, after the zinc oxide lightning arrester is installed on a power line, when lightning strikes, the high voltage of lightning waves breaks down the piezoresistor, lightning current flows into the ground through the piezoresistor, and the voltage on the power line can be controlled within a safe range, so that the safety of electrical equipment is protected.
