Suspended annular anode saturated reactor

Abstract

A suspend annular anode saturated reactor including fireproof enclosures, Two suspension arms, core radiator, Front composite connection bus bar, first and second hose couplings, Side Connecting Bus Bar, helical radiator, solenoid and core, The shape of the fire-proof enclosure is circular, solenoid, Iron core, spiral radiator, the core radiators are located in a fire-resistant enclosure, the twosuspension arms are respectively protruded from both radial ends of the fire-proof shell, the first hose joint is connected with the liquid inlet and is connected with the inlet end of the helical heat sink through the hose, The outlet end of the spiral heat sink is connected with the electromagnetic coil through a hose, a second hose joint and a coil water connection port, the other end of the electromagnetic coil is connected with a coil water outlet, the coil water connection port is arranged perpendicularly to the coil water outlet port, and the iron core heat sink surrounds the electromagnetic coil and the iron core. As that cool liquid is adopted for heat dissipation, the volume is small, the heat dissipation effect is good, and the installation design is reasonable.

Description

technical field [0001] The invention relates to the technical field of high-voltage power transmission and distribution, in particular to a suspended annular anode saturated reactor. Background technique [0002] Compared with the traditional high-voltage AC transmission technology, the high-voltage direct current transmission technology can greatly improve the transmission capacity and transmission efficiency, and reduce the loss of electric energy during the transmission process. High-voltage direct current transmission is to rectify alternating current into direct current through a converter station, and then send it to the converter station at the power consumption end through a direct current transmission line to invert it into alternating current. The converter valve is the key equipment of HVDC transmission, and the converter valve is composed of a thyristor and an electrical protection device. The valve reactor is a key component used to protect the thyristor in the...

AI Technical Summary

Problems solved by technology

[0003] The existing DC transmission lines in China have been in operation for decades, and the equipment urgently needs to be updated. Among them, the existing valve reactor uses heat sinks for heat dissipation, which is large in size and poor in heat dissipation. Because the design structure is core type, The vibration and noise generated during operation are relatively large. Due to the influence of long-term vibration, the opening of the iron core has loose pieces, which seriously affects the safe operation of the converter valve. The installation design is unreasonable and needs to be improved.
