Description

Technical Field

[0001] The utility model relates to the technical field of resistor cabinet equipment, in particular to a braking resistor cabinet. Background Art

[0002] The brake resistor cabinet is a common power electronic device that is used to convert electrical energy into heat energy for consumption when the motor is braked. It is suitable for energy consumption braking circuits of high-power, high-current braking equipment, test equipment, elevators, hoists, and other frequency converters.

[0003] In some humid environments, brake resistor cabinets are mostly installed at high places to prevent moisture inside the resistor cabinet. When the resistor cabinet is suspended and installed at high places, there is a risk of collision, which can easily cause damage to the internal resistors. The traditional protection method is to put a shell on the outside of the brake resistor cabinet. The shell needs to be fixed with bolts, which is cumbersome to install and disassemble, and has low anti-collision ability.

[0004] To this end, we propose a braking resistor cabinet. Utility Model Content

[0009] By adopting the above technical solution, the connecting plate is connected to the slide grooves of the upper sliding frame and the lower sliding frame. At this time, the connecting plate is pushed, the limiting ball moves outward and squeezes the compression spring on the corresponding side. As the connecting plate moves, when the compression spring pushes the limiting ball to be fully inserted into the groove, the installation of the connecting plate and the cabinet is completed. The operation is simple, and the installation and disassembly are convenient, thereby improving the lifting efficiency.

[0010] By using the first connecting spring connected to the outer side of the first connecting block and the second connecting block, when the protective plate is squeezed, the force is reversed to reduce energy, and by changing the angle of the first connecting rod and the second connecting rod, the second connecting spring is driven to move, and the second connecting spring reversely reduces energy, ensuring that when the brake resistor cabinet is hit, it plays a second layer of buffering protection, thereby improving the service life of the brake resistor cabinet.

[0011] Furthermore, a first connecting spring is connected to the outer side of the first connecting block, and a second connecting block is connected to the inner side of the first connecting spring.

[0012] Furthermore, a first pad is connected to one side of the connecting plate, an end of the first pad away from the connecting plate is connected to a first connecting rod, and the other end of the first connecting rod is connected to a connecting piece.

[0015] Furthermore, the shape of the first connecting block is matched with the internal shape of the first connecting spring, and the first pad, the first connecting rod, the second connecting rod, the connecting member, the second connecting spring and the second pad are each provided in two groups.

[0016] Furthermore, the top four corners of the cabinet are fixedly connected with hanging rings, the bottom of the cabinet is fixedly connected with two sets of oppositely arranged supporting legs, one side of the cabinet is provided with a cabinet door, and the upper and lower parts of one side of the cabinet door are provided with heat dissipation nets.

[0017] By adopting the above technical solution, the lifting rope is passed through the lifting ring and then lifted to a high place with the hook of professional equipment such as a crane, making the design of four sets of hooks more stable during the lifting process.
