Problems solved by technology

[0004] This technical solution can improve the distance measurement accuracy of the line, and then improve the transmission line fault analysis to obtain the fault distance measurement result; however, the hidden safety hazards in the line cannot be dealt with in time, and the power supply cannot be cut off immediately, which will lead to high-voltage transmission line accidents Occurrence; this method does not prevent the occurrence of line faults in time to improve the ranging accuracy of high-voltage transmission lines, and will eventually affect the safety of the line

Embodiment Construction

[0031] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0032] Such as Figure 1 to Figure 6 As shown, a high-voltage transmission line protection method, the method includes the following steps:

[0033] Step 1: Install the protection component into the line connected to the refrigerator;

[0034] Step 2: Turn on the switch of the protection component connected in Step 1 and turn on the refrigerator to power on;

[0035] Step 3: The fuse of the protection component energized in step 2 is automatically disconnected when the refrigerator circuit fails;

[0036] Step 4: Automatically rotate the protection component whose fuse is automatically disconnected in step 3 to reconnect the next set of fuses;

[0037] Step 5: Handle the line failure in step 4 and manually turn on the power-off switch to re-ene...

Abstract

The invention belongs to the technical field of line safety, in particular to a high-voltage transmission line protection method. The protection component in the method comprises a main body, a starter switch, a heat dissipation unit, a fixing clasp, a connecting unit, a fixing seat, an automatic rotating device and a fuse. The upper end of the main body is provided with a start switch; A main body of that invention is connected with a main device through a fixed clasp. A connecting unit composed of a plurality of groups of automatic rotating devices is arranged inside the main body; At the same time of power off, the electromagnet loses power, and the spiral rod pushes the radiating fan to rotate by disconnecting the control of the radiating fan, so as to realize the function of radiatingheat; The invention can immediately disconnect and energize when the transmission line fails, effectively avoids the fire caused by the transmission line failure, prevents the occurrence of possibleelectric shock accident, ensures the safety while realizing the right, and can automatically restore the line connection according to the line, so that the working personnel can reduce the number of replacing the fuses.

Description

technical field [0001] The invention belongs to the technical field of line safety, in particular to a method for protecting high-voltage transmission lines. Background technique [0002] The electricity generated by the power plant is not only used by nearby people, but also transmitted to distant places to meet more needs. Transmission lines are often connected to a large power plant at one end and a load center at the other end, or to a large power system at both ends. These electricity cannot be transmitted directly through ordinary wires, but must be transmitted by high-voltage transmission lines. Generally, the transmission voltage below 220 kV is called high-voltage transmission. With the rapid increase of the capacity of the power system and the increasing number of transmission lines, the advantages of high-voltage transmission lines are revealed. The advantage of high-voltage transmission lines is that high-voltage transmission is a process in which the voltage ou...
