Abstract
An inverter module of a variable frequency generator includes a housing with cooling fins, a regulating module, a circuit board provided with inverter circuit and control circuit, wherein the regulating module is electrically connected to the inverter circuit and the control circuit through lead wires, and the bottom board of the regulating module is connected to the inner bottom of the housing, and an insulated heat conducting plate is arranged between the regulating module and the inner bottom of the housing. The utility model can reduce AC high voltage damage to other parts of the generator system, as well as prevent the regulating module being reversely damaged by other AC high voltage in the generator system.
Description
Technical field
The utility model relates to electric and electronic technical field, particularly a kind of frequency conversion generator inverter module.
Background technology
At present, in being provided with the frequency conversion generator inverter module of rectification module, its rectification module base plate all is directly to be connected on the flange-cooled shell inner bottom surface of frequency conversion generator inverter module, the heat that this structure makes rectification module internal rectifier part produce can be directly delivered on the shell of frequency conversion generator inverter module its compact conformation, perfect heat-dissipating.
But, being provided with the very thin insulating trip of one deck between the connected rectifying device of the base plate of described rectification module, described base plate, rectifying device, insulating trip three have capacity effect, a promptly described insulating trip stopping direct current after connecting.After the frequency-changing AC voltage of generator is added on the above-mentioned rectifying device, its alternating current will be transmitted on the flange-cooled shell, make above-mentioned shell have ac high-voltage to exist, thereby the generator system other parts are easily produced the ac high-voltage injury.
Summary of the invention
The utility model purpose provides a kind of improved frequency conversion generator inverter module, it is reduced the generator system other parts are produced the ac high-voltage injury.
Frequency conversion generator inverter module described in the utility model, comprise flange-cooled shell, rectification module and be provided with inverter circuit and the circuit board of control circuit, rectification module is electrically connected with inverter circuit and control circuit by lead-in wire, the rectification module base plate connects the end in the shell, is provided with the insulating heat-conductive plate in described rectification module base plate and the shell at the end.The utility model can reduce the generator system other parts are produced the ac high-voltage injury, can reduce also that other ac high-voltage oppositely produces injury to the rectification module in the utility model in the generator system.
Can be provided with insulating bushing in the screw hole at two ends, the described rectification module base plate left and right sides, when screw is connected rectification module base plate and flange-cooled casing insulation.
The utility model owing to set up insulating barrier at the end in rectification module base plate and flange-cooled shell, so effectively increased the interchange insulation resistance that the rectification module base plate is connected with band fin shell, after making generator frequency-changing AC voltage be added on the rectification module, the utility model will significantly reduce the generator system other parts will be produced the ac high-voltage injury, can reduce equally also that other ac high-voltage oppositely produces injury to rectification module in the generator system.
