Description
Technical field
The utility model belongs to a kind of power electronic power device cabinet, refers in particular to a kind of electric driving electronic power converter high voltage control cabinet.
Background technology
Electric driving electronic power converter is a crucial semiconductor power device during a kind of fax is moved, because electric driving electronic power converter has energy-conservation, noise reduction, quickens characteristics such as steady, quick response, and its range of application more and more widely.As the DC/DC converter is to be variable direct voltage with a fixing dc voltage conversion, this technology is widely used in the infinitely variable speeds and the control of trolley bus, subway train, electric motor car, make above-mentioned control obtain the performance of quickening steadily, responding fast simultaneously, and receive the effect of saves energy.But replace rheostat saves energy (20～30) % with DC/DC.DC/DC can not only play pressure regulation (Switching Power Supply), can also play the effect that suppresses grid side harmonic current noise effectively simultaneously.Present electric driving electronic power converter generally comprises high voltage control and two parts of power control, and wherein the high voltage control part mainly is that some high pressure motion devices such as non-heater elements such as fuse, main contactor, auxiliary contactor and charging resistor are formed.But existing electric driving electronic power converter, general all is with all power electronic device, the device that comprises two parts of high voltage control and power control, all be installed in the same Electric Appliance Cabinet, in actual motion, find all power electric components of electronic power converter all are installed in the device cabinet, make Electric Appliance Cabinet seem very huge one side, the weight of entire device increases the weight of, and installation and transportation are all inconvenient; On the other hand, because all devices are installed in together and also will influence each other, the Electro Magnetic Compatibility of device integral body descends, and particularly heater element is bigger to the influence of heater element not, therefore necessary this is improved.And in patent documentation search, still find no the report of pass to electric driving electronic power converter high voltage control partial content to China.
Summary of the invention
The purpose of this utility model is the deficiency at existing electric driving electronic power converter high voltage control partial design and layout, proposes a kind of high-pressure control device of novel electric driving electronic power converter.
According to the technology implementation scheme that the purpose of this utility model proposed be: the high voltage control part and the power control section of electric driving electronic power converter are divided to carry out split, the device of the high voltage control of electric driving electronic power converter part is arranged separately in the device case, the device case is an airtight metal cabinet with cover, the main contactor of the high voltage control part of electronic power converter is installed in the casing at least, high tension apparatus such as auxiliary contactor and charging resistor, these devices are installed concentratedly one with in power control section is divided relative device case independently with cover, the order that implementation is come in and gone out by power supply is arranged in order, also be provided with the cable joint that is used for electric-connection on casing or case lid, what high voltage control part and power control section were divided connects electric the connection by tie cable.In order to understand the ruuning situation of high tension apparatus, in casing, the voltage sensor that is used to monitor high-voltage control circuit can also be installed.
The utility model is owing to adopted the electric driving electronic power converter high voltage control cabinet of external, thereby significantly reduced of the interference of electric driving electronic power converter high-pressure section, and whole electric driving electronic power converter was much smaller than in the past also to power device.Make more compact structure, more reasonable.
