Description
Technical field
The utility model relates to a kind of frequency converter, especially a kind of three-phase converter module modularization flame-proof mine frequency converter that is applicable under the coal mine.
Background technology
The flame-proof mine frequency converter is used under the ore deposit; Because underground coal mine electrical equipment will reach requirement of explosion proof, be at the outside explosion-proof casing of installing of electric equipment, the electric equipment of installing in the tight anti-explosion enclosure interior is difficult for heat radiation; And the caloric value of frequency converter is bigger; Its main heating parts IGBT power cell is bad in running heat radiation, gently then causes the equipment operation unstable properties, and is heavy then cause IGBT power cell scaling loss and then cause whole equipment scrapping.
Solving at present IGBT power cell heat dissipation problem mainly adopts the IGBT power cell is directly fixed on the heat-radiating substrate that is connected through flange with explosion-resistant enclosure; The outside forced heat-exchanging that heat pipe or cooling water pipe realization substrate are installed of heat-radiating substrate; Because frequency converter IGBT power cell is positioned at the heat-radiating substrate place; Each control and bus capacitor are positioned at its top, and the product I&M is inconvenience extremely, and many problems and fault all are because the complicated technology in the I&M process causes.
Summary of the invention
For overcoming above-mentioned defective, the utility model provides a kind of heat dispersion good, makes things convenient for the three-phase converter module modularization flame-proof mine frequency converter of product assembling, maintenance.
The utility model provides a kind of three-phase converter module modularization flame-proof mine frequency converter; Comprise panel, capacitance component, IGBT power unit module, rectification unit, copper bar, master control borad, heat-radiating substrate; Master control borad and heat-radiating substrate are arranged on the panel; IGBT power unit module and rectification unit are fixed on the heat-radiating substrate, and capacitance component is fixed on the panel through link, and IGBT power unit module, rectification unit and capacitance component are connected through copper bar.
The utility model further is set to said master control borad and is connected with the IGBT power unit module through optical fiber.
The utility model beneficial effect is that IGBT power unit module and rectification unit are fixed on the heat-radiating substrate, and heat dispersion is good, and electrical structure is simple, and wiring is succinct, makes things convenient for actual product assembling, maintenance, and high-low pressure is isolated.
