Description

Technical Field

[0001] The utility model relates to the technical field of generator boxes, in particular to a variable frequency generator set box which is easy to disassemble and maintain. Background Art

[0002] Generators are usually composed of stators, rotors, end covers, brushes, machine bases and bearings. The stator is composed of machine bases, stator cores, wire windings, and other structural parts that fix these parts. The rotor is composed of rotor cores, rotor poles, slip rings, fans, and shafts. The stator and rotor of the generator are connected and assembled through bearings, machine bases and end covers so that the rotor can rotate in the stator. A certain excitation current is passed through the slip rings to make the stator a rotating magnetic field. The stator coil cuts the magnetic lines of force, thereby generating an induced potential, which is led out through the wiring terminals and connected to the circuit to generate current. During the installation of the variable frequency generator set, the set is generally installed in the chassis for use.

The utility model does not require the use of tools for the installation and disassembly of the chassis, which saves more manpower, improves efficiency, and is more convenient for the inspection and maintenance of the chassis.

[0004] However, there are still some shortcomings in the use of the above-mentioned generator set box. The generator set is installed deep inside the box. After the box door is opened during maintenance, the generator set is still in a relatively deep position inside the box, and the maintenance personnel are required to lean into the box, which is troublesome and inconvenient for maintenance. Utility Model Content
