Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage power transmission, in particular to a combined shielding cover for high-voltage power transmission. Background Art

[0002] High-voltage power transmission is a method of transmitting power by boosting the voltage output by a generator using a transformer in a power plant. The reason for using this method of transmission is that under the condition of the same transmission power, the higher the voltage, the smaller the current. In this way, high-voltage transmission can reduce the current during transmission, thereby reducing the heat loss caused by the current and reducing the material cost of long-distance transmission. The electric energy generated by the power station is generally sent to various power consumption places through transmission lines. Different high voltages are used according to the distance of the power transmission. The existing patent, patent announcement number CN211047754U, discloses an assembled shielding cover for high-voltage power transmission equipment, including a mounting base, the mounting base is sequentially provided with through holes and annular grooves from the inside to the outside, the outer side of the upper end of the mounting base is provided with annular symmetrically distributed countersunk holes, the countersunk bolts are provided in the countersunk holes, the lower shielding cover is clamped and connected in the annular groove, the upper end of the lower shielding cover is movably connected to the middle shielding cover and the upper shielding cover, and the upper end of the upper shielding cover is provided with a circular hole. The assembled shielding cover for high-voltage power transmission equipment adopts a multi-section design to assemble various parts together for easy installation and transportation. It has a simple structure and is easy to use. It strengthens the firmness of the connection between the lower shielding cover, the middle shielding cover and the upper shielding cover, effectively avoids the loss of the U-shaped connecting rod, ensures the integrity of the shielding cover, and further strengthens the stability of the installation between the mounting base and the lower shielding cover by positioning the threaded rod and the limit ring, ensuring the normal heat dissipation of the high-voltage power transmission equipment in the shielding cover.

[0003] Regarding the above-mentioned related technologies, the inventors believe that the following defects exist: in actual application, it is necessary to open and close it. In the subsequent use process, if it is inconvenient to open and close it, the subsequent use will affect the convenience of using the shielding cover and reduce the efficiency of using the shielding cover. Therefore, we proposed a combined shielding cover for high-voltage transmission to solve the above-mentioned problems. Utility Model Content
