Water-cooling box type movable ice melting device

Abstract

The invention discloses a water-cooling box type mobile ice melting device which comprises a box body, an air cooler, power electronic rectification equipment, protection equipment and water cooling equipment. The box body is divided into a first cabin body, a second cabin body and a third cabin body which are connected in sequence and independent of one another; the air cooler is arranged outsidethe box body; the power electronic rectification equipment is arranged in the first cabin body; the protection equipment is arranged in the second cabin body; the water cooling equipment is arrangedin the third cabin body and comprises a water cooling body, a first pipe body, a second pipe body, a third pipe body and a fourth pipe body, the first pipe body, the second pipe body, the third pipe body and the fourth pipe body are connected with the water cooling body, and the first pipe body and the second pipe body penetrate through the second cabin body and then are led to a thyristor siliconstack in the power electronic rectification equipment; and the third pipe body and the fourth pipe body respectively penetrate through the box body and are led to an air cooler. Compared with a conventional air-cooled movable ice melting device, the movable ice melting device has the advantages of being low in noise, high in cooling efficiency, small in influence of the external environment and the like, and miniaturization of the movable ice melting device can be achieved.

Description

technical field [0001] The invention belongs to the technical field of ice-melting devices, and in particular relates to a water-cooled box-type mobile ice-melting device. Background technique [0002] In early 2008, the low-temperature, rain, snow and freezing disaster caused serious damage to power grid facilities in most areas of Guizhou, northern Guangxi, northern Guangdong, and northeastern Yunnan in the Southern Power Grid region, and the west-to-east power transmission was also seriously affected. In order to improve the power grid's ability to resist extreme weather and major natural disasters, the use of DC ice melting is a feasible, economical and effective anti-icing measure. The DC ice-melting device adopts silicon-controlled rectification. Its principle is to take the 10kV or 35kV busbar AC power of the substation, and provide DC ice-melting power for the transmission line through the 12-pulse rectifier. Short the out-of-service wires at the end, and the direct...

Problems solved by technology

[0003] In recent years, DC deicing has become a vehicle-mounted mobile requirement. The DC deicing is integrated into the container and installed on the vehicle board. The main cooling method is air cooling, but its heat dissipation efficiency is low. Long-distance deicing and large-scale If the mobile ice melting under the current working condition adopts the air-cooled form, the rectification equipment will be bulky, requiring multiple vehicles to be used together, and the on-site ice melting construction is cumbersome
