The utility model content
The utility model provides a kind of oil field supply line automatic throwing type lightning arrester; On the basis of original drop type zinc oxide arrester, installed the heat explosion type disconnector additional, promptly automatic throwing type lightning arrester, this product can utilize the power frequency short circuit current; The disconnector earth terminal is thrown off automatically; In time make unit of an arrester turn over, the accident that prevents further enlarges, and is easy to the attendant and in time finds to safeguard and change.
In order to address the above problem, the utility model adopts following technical scheme:
The automatic throwing type lightning arrester of a kind of oil field supply line; Comprise an insulating support; The upper end connection that it is characterized in that said insulating support is provided with a upper static contact connector; Its lower end is provided with ground connection fixed contact, and said upper static contact connector is connected setting with following ground connection fixed contact with the two ends of a zinc oxide arrester, and the lower end of said zinc oxide arrester is provided with a heat explosion type disconnector.
Further, said heat explosion type disconnector is provided with down the ground connection moving contact through lead connection, and said ground connection moving contact down is connected with the assembling of said ground connection fixed contact down.
Further, said upper static contact connector connection is provided with a high-voltage conducting wires link, and the upper end of said zinc oxide arrester is provided with moving contact connector on, and moving contact connector connects said upper static contact connector on this.
Further, the connection of said ground connection moving contact down is provided with ground connection moving contact, and the connection of this time ground connection moving contact is provided with said zinc oxide arrester.
Further, said mounting bracket is provided with and the installation portion that becomes the assembling of platform cross-arm or circuit cross-arm.
The beneficial effect of the utility model is:
