Abstract
The utility model discloses a high-voltage alternating current lightning arrester which comprises a lighting arrester body and an insulation portion. The insulation portion is arranged at the top of the lighting arrester body, the insulation portion comprises an insulation terminal which is arranged at the top of the lighting arrester body, clamping sheets are arranged at two ends of the insulation terminal, a lightning shielding breaking device is arranged between the clamping sheets at the two ends, and two ends of the lightning shielding breaking device are connected to the clamping sheets at the two ends through flexible connection wires. The high-voltage alternating current lightning arrester is simple in structure, and the insulation portion is arranged at the top of the lighting arrester body, so that when the lighting arrester body short-circuits, isolation of the lighting arrester body from a contact net can be guaranteed, effects without maintenance are achieved, and the using is convenient.
Description
Technical field
The utility model belongs to the lightning-arrest field of high-voltage alternating, is specifically related to a kind of high-voltage alternating lightning arrester.
Background technology
Adopting the electrified overvoltage of high-voltage alternating lightning arrester limiting AC, is the effective means that improves the attached wires of AC electrified reliability.But at present the high-voltage alternating lightning arrester adopts the deficiency of arrester without gaps protection, be or short trouble deteriorated at lightning arrester after, can cause the electric power system short circuit, cause grave danger for the reliable power supply of contact line.
Summary of the invention
The purpose of this utility model provide a kind of simple in structure, do not need the high-voltage alternating lightning arrester safeguarded.
The technical scheme that realizes the utility model purpose is a kind of high-voltage alternating lightning arrester, comprise lightning arrester body, be arranged on the insulation division at lightning arrester body top, described insulation division comprises insulated terminal, described insulated terminal is arranged on the top of lightning arrester body, the two ends of described insulated terminal are provided with holding piece, be provided with lightning-arrest disconnecting apparatus between the holding piece of two ends, the two ends of described lightning-arrest disconnecting apparatus are connected on the holding piece of two ends by soft wiring.
Described lightning-arrest disconnecting apparatus is the shunting decoupler.
The utlity model has positive effect: of the present utility model simple in structure, be provided with insulation division at the lightning arrester body top, can guarantee that lightning arrester body is short-circuited after, with the isolation of lightning arrester body and contact line, thereby not needing to have realized the effect safeguarded, easy to use.
