Abstract

The invention provides a thyristor switch type controllable lightning arrester which comprises a lightning arrester controlled part, a thyristor valve, a first connection module and a second connection module. The first end of the lightning arrester controlled part is electrically connected with the first end of the thyristor valve via the first connection module, the second end of the lightning arrester controlled part is electrically connected with the second end of the thyristor valve via the second connection module, the first connection module is disconnected according to a disconnectioninstruction, a first feedback signal of disconnection of the first connection module is sent to the second connection module, the second connection module rotates the thyristor valve from a first position to a second position according to the first feedback signal, when a second feedback signal which indicates replacement of the thyristor valve is completed, the thyristor valve is rotated from thesecond position back to the first position, a third feedback signal is sent to the first connecting module, and the first connection module is closed according to the third feedback signal. Thus, thethyristor valve is maintained in the live-line manner, and the reliability and anti-risk capability of a system are improved.

Description

technical field [0001] The invention relates to the technical field of power system maintenance, in particular to a thyristor switch type controllable arrester. Background technique [0002] In the UHV AC transmission system, the saturation characteristic of the air gap operation impulse discharge voltage is more significant, and the deep reduction of the operating overvoltage level plays a vital role in reducing the line air gap. [0003] The existing solution to reduce the operating overvoltage is to use a conventional thyristor switch-type controllable arrester, and use the thyristor valve body to limit the operating overvoltage caused by closing or single-phase reclosing, which can deeply reduce the operating overvoltage. However, once the thyristor valve body fails, the overall surge arrester can only be out of operation first, and the maintenance or replacement of the thyristor valve body can be carried out in an environment where the overall arrester is not charged.
