[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] This utility model provides a resistor for wind power, such as Figures 1 to 4 As shown, the device includes a resistor body 1, with a main control board 2 movably latched on both sides of the resistor body 1. Limiting baffles 201 are provided on both sides of the upper surface of the main control board 2, and top sealing edges 202 are provided on both sides of the upper surface of the limiting baffles 201. The lower surface of the top sealing edges 202 rests on the resistor body 1. Abutment edges 203 are provided at both the front and rear ends of the upper surface of the main control board 2. One side of the abutment edges 203 is placed between the front and rear ends of the resistor body 1. A rivet nut 3 is fixedly installed on the upper surface of the top sealing edge 202. A top cover plate 4 is fixedly installed between the rivet nut 3 and the top sealing edge 202. The upper surface of the top cover plate 4 is connected to the rivet nut 3 through it. The lower surface of the top cover plate 4 is attached to the surface of the resistor body 1. A connecting hole 401 is provided on the side of the upper surface of the top cover plate 4 near the rivet nut 3. Terminal components 5 are provided on both sides of the inner bottom wall of the main control board 2, and a connecting part 501 is provided in the middle section of the upper surface of the terminal component 5.
[0025] The main control board 2 has horizontal plates at its two sides and the connection points 201 with the limiting baffles, as well as at its bottom. These plates are designated as top sealing edges 202 and abutment edges 203. During installation, the upper part of the resistor body 1 is mounted using the main control board 2. The top sealing edge 202 is in close contact with the surface of the resistor body 1, serving as a limiting element. The two sides contact the abutment edges 203, which act as limiting points to ensure the accuracy of the resistor body 1's installation position. The top cover plate 4 is pressed into the resistor body 1 at the bottom of the main control board 2 by the rivet nuts 3. In this way, the resistor body 1 is... Securely and reliably fixed to the main control board 2, the main control board 2 is electrically connected to the controller via connector 6. When the resistor body 1 fails and needs to be replaced, maintenance personnel only need to unplug the connectors 6 at the top cover plate 4, slightly loosen the top rivet nuts 3, and lift the top cover plate 4 to quickly remove the resistor body 1. This simplifies the resistor replacement process, significantly shortens maintenance time, effectively reduces downtime caused by equipment failure, lowers maintenance costs, and improves the stability and reliability of wind power equipment operation, providing strong support for the efficient development of the wind power industry.
[0026] The upper surface of the connecting part 501 is provided with a screw locking hole 502. The terminal component 5 is provided with a buffer part 503 near the front end of the connecting part 501. There are two buffer parts 503, and there is a gap between the two buffer parts 503. The upper surface of the two buffer parts 503 is provided with a connecting terminal 504. A through hole is provided on the top of one side surface of the connecting terminal 504. A connector 6 is connected through the through hole at the front end of one side of the connecting terminal 504. There are two connectors 6. One connector 6 is connected through to the inside of the connecting hole 401. A wire 601 is provided between the two connectors 6. A spring 7 is provided on the side of the connecting terminal 504 away from the connector 6. One end of the spring 7 is placed on one side of the resistor body 1. There are two springs 7, and they are symmetrically distributed with the resistor body 1 as the center point.
[0027] In the construction of the wind power resistor, the resistor body 1 has a connecting part 501 on both sides of the bottom. A buffer part 503 is provided on one end face of the connecting part 501. When the resistor body 1 is subjected to external pressure, the buffer part 503 can effectively absorb part of the impact energy. At the same time, the remaining impact force will be buffered by the abutment of the spring 7. In this way, the stability of the resistor body 1 under complex working conditions is greatly enhanced, and the risk of internal structural damage caused by vibration or impact is reduced.
[0028] As the core component of the circuit connection, the connection terminal 504 increases the contact area with the lead of the resistor body 1, thereby effectively reducing the contact resistance. When current flows into the connection terminal 504 from the external circuit, under the drive of the electric field, electrons can smoothly cross the contact interface between the connection terminal 504 and the lead of the resistor body 1 and stably enter the resistor body 1, thereby achieving precise control and regulation of the current. This ensures stable current transmission and strongly guarantees the stable operation of the resistor body 1 in the wind power system. Good connection conditions can significantly reduce the potential for overheating, arcing and other faults caused by poor contact, and improve the reliability and stability of the entire wind power system.
[0029] The connector 6 is mainly responsible for the electrical connection and signal transmission between the connector terminal 504 and the resistor body 1. During the operation of the wind power system, the control signal and operating current from the connector terminal 504 are transmitted to the resistor body 1 through the conductive components inside the connector 6. The connector terminal 504 will send instructions to the resistor body 1 through the connector 6 according to real-time parameters such as the grid voltage to adjust the resistance value, thereby realizing the optimized control of the wind turbine's operating status.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
