Problems solved by technology
[0004] Many lightning rods that were put into operation in the early years are inconvenient to maintain due to their age. Especially the lightning rods on the upper part of the equipment structure must be repaired after a large-scale power outage, which makes the corrosion of the lightning rods become more and more serious. It may cause the lightning rod to collapse, resulting in large-scale power outages and equipment damage accidents, and the lightning rod will seriously endanger the safe operation of the surrounding area.
[0005] The overall replacement of lightning rods requires simultaneous power outages at adjacent intervals. It takes more than 2 days to replace a group of lightning rods. In the case of power shortages, power outages are difficult to achieve
In addition, the overall replacement of the lightning rod also requires a large number of operations of stopping power transmission, entering the bypass and reversing the bus. These operations will also waste a lot of manpower and vehicle costs, and will also bring certain risks to the operation. The change of operation mode brings unreliable operation of the power grid

The invention discloses a reinforcing support frame of an open type transformer substation framework lightning conductor. The reinforcing support frame is characterized by comprising a lower strut body, wherein the lower strut body consists of an upper bottom plate (1), a lower bottom plate (4), struts (2) and cable stayed support frames (3), wherein the struts (2) are arranged between the upper bottom plate (1) and the lower bottom plate (4), the cable stayed support frames (3) are connected among the struts (2), the four struts (2) are connected between the upper bottom plate (1) and the lower bottom plate (4), the cable stayed support frames (3) are connected between every two struts (2), and the upper part of the lower strut body is provided with a clamp hoop device (5). The reinforcing support frame has the advantages that the structure is simple, the cost is low, the installation power failure range is small, the power failure time is short, the mechanical strength is enhanced, the enterprise cost is reduced, and the safe and reliable operation is ensured.
Description
[0001] Technical field: [0002] The invention relates to a reinforcing bracket for a lightning rod of an open substation structure, which is widely used in strengthening the lightning rod of an open substation structure in a power system, and belongs to the field technical field of substation maintenance. Background technique: [0003] Lightning protection devices against direct lightning strikes mainly include lightning rods. The lightning protection principle of the lightning rod as a lightning terminal is: the lightning rod is connected to the ground through a wire, and forms an equipotential difference with the ground. Using its own height, the electric field of the lightning cloud whose electric field intensity increases to the limit value is distorted, and begins to ionize and lead downward. Discharge; the lightning rod produces a tip discharge under the action of a strong electric field, forming an upward leading discharge; the two meet to form a lightning path, and ...
