Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage transmission line monitoring, in particular to a high-voltage transmission line monitoring device. Background Art

[0002] High-voltage power transmission is a method of transmitting the voltage output by the generator by using a transformer in a power plant. The reason for using this method of power transmission is that under the same transmission power, the higher the voltage, the smaller the current. In this way, high-voltage power transmission can reduce the current during transmission, thereby reducing the heat loss caused by the current and reducing the material cost of long-distance power transmission. The electric energy generated by the power station is generally sent to various places where electricity is consumed through transmission lines. Different high voltages are used according to the distance of the transmission of electric energy. The high-voltage transmission line needs to be monitored in real time by a monitoring device to ensure that the line is always in a stable state. However, most of the existing high-voltage transmission line monitoring devices use a cumbersome bolt tightening method when in use, and it is difficult for maintenance personnel working at heights to quickly disassemble and assemble the equipment during daily use, which affects the convenience of daily use of the equipment.

[0026] For further information, see Figure 3 An inclined surface 16 is disposed on one end surface of the limiting plate 301 located in the fixing groove 4 .

[0027] Preferably, the fixing column 6 and the clamping plate 7 are perpendicular to each other, and the clamping plate 7 is parallel to the end face of the monitor body 1 adjacent to the fixing column 6.
