Problems solved by technology

The closed cooling tower often forms a large amount of scale due to poor water quality. If the ambient temperature is too high, the heat transfer effect of the closed cooling tower will be poor, and the cooling medium temperature of the inlet valve cannot meet the normal operation requirements of the converter valve.

Abstract

The invention provides an immersed type thermoelectricity refrigeration device for a direct current converter valve. The device comprises a thermocouple pile arranged between a hot-end radiator and a cold-end radiator, wherein the hot-end radiator is arranged in a direct current converter valve water outlet pipeline of a direct current converter valve enclosed water cooling system, and the cold-end radiator is arranged in a water inlet pipeline of the direct current converter valve. The device is characterized in that the thermocouple pile is connected with a commutator and a direct current power source to form a loop. Compared with the prior art, the immersed type thermoelectricity refrigeration device for the direct current converter valve has advantages of excellent heat transfer performance, simple structure and convenient operation and can realize all-day-long control of in-valve water temperature.

Description

technical field [0001] The invention relates to a thermoelectric refrigeration device, in particular to a submerged thermoelectric refrigeration device for a DC converter valve. Background technique [0002] With the increasing maturity of high-voltage direct current transmission technology in my country, the construction of direct current transmission projects is in the golden period of development. In the HVDC transmission system, the cooling system is an important component of the converter valve cooling system, and its operation directly affects the transmission capacity of the entire HVDC system. Therefore, it is particularly important to ensure the stable, reliable and efficient operation of the cooling system. [0003] The closed water-cooling system is widely used in the cooling of DC transmission converter valves at present. The temperature resistance of the water-cooling system directly affects the climate and geographical environment of the converter valve. In p...
