The utility model electric control panel includes electric motor protecting main circuit, control circuit, signal designation and audio alert（1）Circuit, time block（2-10）, in input one three-phase breaker of series connection of main circuit（2-3）, the common port concatenation fuse of main circuit（2-19）, in the input of main power source three three-phase voltage meters in parallel（2-1）And a motor protecter（2-18）, two A.C. contactors in parallel in motor main circuit（2-16）And one electrothermal relay of series connection（2-17）；Parallel connection one in circuit is controlled to control transformer（2-20）, series connection scram button（2-8）, key switch（2-2）, manual/auto change-over switch（2-15）, motor protecter（2-18）And electrothermal relay（2-17）Normally-closed contact；Signal designation and audio alert（1）Series connection human inductor and voice alarm module A1, A2 in circuit；Time block（2-10）Mainly digital display time relay.Electric control panel is fixed on inside control box, and control lid plate is locked provided with cover plate, and control box can be positioned on stroller.
The desirable following technique effect of the utility model：
1st, gear case oil pump motor can be conveniently controlled, when the direction of Oil pump electrical machinery rotation direction and actual requirement is inconsistent；Only need the i.e. changeable direction of rotation of operational control button, it is to avoid be again off the trouble that power supply deduplication exchanges phase sequence；
2nd, provided with different indication signals, while there is different voice prompt alarm functions, by watching signal lamp, listening the alarm sound can clearly to judge the working condition of gear-box washing oil control device；
3rd, potential safety hazard is eliminated provided with phase shortage, misphase, overload, short circuit, interlocking every electic protection measure to whole circuit, it is safe and reliable；
4th, being not required to operating personnel's moment during washing oil stands and keeps an eye at the scene, saves man-hour, improves operating efficiency；
5th, small volume, lightweight, easy to operate simple, appearance design is attractive in appearance, live conveniently moving, alleviates the labor intensity of operator.
