Description
Technical field
The utility model relates to lightning arrester field, particularly relates to a kind of lightning arrester.
Background technology
The prevailing overvoltage protection device of current China is metal oxide arrester.When metal oxide arrester uses, by lightning arrester and protected equipment earth.Namely lightning arrester high voltage end is in parallel with protected equipment, lightning arrester low-pressure end ground connection.When having high voltage in such electric power system, overvoltage energy is released into ground by lightning arrester, effectively can protect the safety of electric power system.Metal oxide arrester is all made up of zinc oxide nonlinear resistance slice serial or parallel connection.Zinc oxide nonlinear resistance slice is the core parts of lightning arrester.The basic application principle of lightning arrester, be exactly that the rated voltage of lightning arrester is designed near the reference voltage of zinc oxide resistance sheet, the electric current that lightning arrester flows through under rated voltage effect is milliampere level, and the electric current flow through under continuous operating voltage is microampere order, be the same order of magnitude with the leakage current of other electric equipments.Namely under normal working voltage, zinc oxide resistance sheet is high value, can long-term safety run.Under the effect of big current overvoltage, as switching impulse overvoltage, lightning impulse overvoltage, zinc oxide resistance sheet shows as low resistance, the residual voltage value at restriction lightning arrester two ends, thus the overvoltage suffered by electric equipment is limited in allowed limits.
Utility model content
The utility model is in order to overcome deficiency of the prior art, and provide a kind of lightning arrester, the utility model installs convenient and swift, and effect is good, has well lightning-arrest effect, fully ensures the safety of electric equipment.
The utility model is achieved through the following technical solutions:
A kind of lightning arrester, comprise the support of lightning arrester and fixing lightning arrester, described lightning arrester comprises insulator and is encapsulated in the zinc oxide core body in insulator, it is characterized in that: described lightning arrester is connected by clamp ring with insulating support, described insulating support is connected with fixed head, be provided with bottom electrode below described lightning arrester, bottom electrode is connected by wire with fixed head.
Be provided with top electrode above described lightning arrester, top electrode is provided with connector lug.
Described insulating support and fixed head are bolted to connection.
Described fixed head is provided with set bolt.
Compared with prior art, the beneficial effects of the utility model are: the utility model provides a kind of lightning arrester, and the utility model installs convenient and swift, and effect is good, have well lightning-arrest effect, fully ensure the safety of electric equipment.
