According to the mine explosion-proof driver integrating the frequency converter and the electric motor, the frequency converter and the electric motor are arranged in the same explosion-proof box body, thus the frequency converter and the electric motor are provided with the explosion-proof performance; and the mine explosion-proof driver integrating the frequency converter and the electric motor has the advantages of convenient installation and debugging, low assembly cost, good use safety performance, and is especially suitable for coal mine underground operation.
Description
Technical field
The utility model relates to a kind of improvement of driving arrangement, specifically a kind of mine explosion-suppression driving arrangement that integrates frequency converter and motor.
Background technology
Employed driving arrangement under mine mainly is the motor of installing separately at present, yet in use, because the variation of load must realize the motor frequency change speed regulating control by frequency converter again.Described frequency converter is independent is installed in the electrical control cubicles without the flame proof function; be connected with terminal box on the motor by power line; frequency converter is the on-off action that utilizes power semiconductor device; power frequency supply is transformed to the electric energy control device of another frequency, can realizes soft start, frequency control, raising running accuracy, change power factor, overcurrent/overvoltage/overload protection alternating current motor.This driving arrangement is because motor and frequency converter are independent the installation, so Installation and Debugging are inconvenient, assembly cost is high; Because motor and frequency converter lack explosion-proof casing, poor safety performance particularly is not suitable under the coal mine and installs.
Summary of the invention
The purpose of this utility model is to provide that a kind of Installation and Debugging are convenient, assembly cost is low, integrate be contained in the explosion-proof casing, usage safety performance is good, the mine explosion-suppression driving arrangement that collects frequency converter and motor that is specially adapted to coal mine operation.
In order to reach above purpose, the technical scheme that the utility model adopts is: this integrates the mine explosion-suppression driving arrangement of frequency converter and motor, comprise frequency converter and motor, it is characterized in that: described frequency converter and motor are installed in the flameproof cabinet jointly, and frequency converter is fixedly mounted on middle part in the flameproof cabinet by support; Motor is fixedly mounted on the interior diapire of flameproof cabinet, and the terminal box of motor is fixed on the interior sidewall of flameproof cabinet, and frequency converter is connected with terminal box by transmission line; The driving shaft of described motor stretches out the sidewall of flameproof cabinet by sealing sheath.
The utility model is also implemented by following measure: the front side of described flameproof cabinet is provided with sealed container door, connect bellows at the rear wall of flameproof cabinet, one port of the heat exchanger in the inner chamber of bellows and the flameproof cabinet is connected, flameproof cabinet is stretched out in the another port of heat exchanger in the flameproof cabinet, and the top in bellows is provided with blower fan; The fixing upper junction box in the left side wall outside of described flameproof cabinet, the circuit termination of frequency converter is located in the junction box.
Described sealing sheath is powder metallurgy sleeve.
The supporting component of described frequency converter comprises A.C. contactor, intrinsic safety electric source, relay assembly, discharge contactor, two D.C. contactors and two transformers that are installed on the flameproof cabinet inner bottom plating, is prior art, therefore seldom state.
The beneficial effects of the utility model are: this integrates the mine explosion-suppression driving arrangement of frequency converter and motor, compare with motor with present employed frequency converter, because frequency converter and motor are installed in the same flameproof cabinet, institute is so that frequency converter and motor have all had explosion insulation performance, Installation and Debugging are convenient, assembly cost is low, usage safety performance good, is specially adapted to coal mine operation.
