Description
Technical field
The present invention relates to a kind of internal combustion locomotive air compressor group control gear, belong to railway locomotive manufacturing technology field.
Background technique
On some internal combustion locomotive, for ensureing that system has enough wind regimes, often two air compressor unit (such as two screw-rod air compressor groups) are adopted to be system air feed.Drive every platform motor of air compressor, its rated power and electric current general all larger, such as rated power is 22kW, and rated current is 245A ± 10%.In the prior art, be always with an air compressor switch control simultaneously two air compressor motor contactor coils electricity condition, two air-compressor set are started or stoped simultaneously.2 ~ 3 times when electric current during electric motor starting is its normal work, while two air-compressor set, this of startup significantly loads suddenly, locomotive auxiliary power supply system instantaneous voltage drop can be caused too low, auxiliary power generation unit is produced and impacts, air compressor motor can cause vicious circle by further high current due to undertension, also can have a strong impact on the normal work of other consumers; And this significantly Condition of Sudden Unloading that two air-compressor set are simultaneously out of service, locomotive auxiliary power supply system instantaneous voltage can be caused too high, can produce auxiliary power generation unit equally and impact, affect the normal operation of other ancillary apparatus equipment.In order to address this problem, often need the auxiliary generator selecting a relatively high power, but this not only can not tackle the problem at its root, and also increases manufacture cost on the contrary.
Summary of the invention
Object of the present invention overcomes the deficiency of above-mentioned prior art exactly, provides a kind of internal combustion locomotive air compressor group control gear.
A kind of internal combustion locomotive air compressor group control gear, comprise switch, pressure switch, first contactor and the second contactor, after electric time delay relay coil and power-off delay relay coils from parallel connection of coils with main switch, pressure switch is connected in series, first contactor coil and after the serial connection of electric time delay relay contact with electric time delay relay coil and power-off delay relay coils from parallel connection of coils, be connected between main switch and pressure switch after second contactor coil and power-off delay relay contact serial connection, first contactor and the second contacts of contactor are connected in series with the first air compressor motor and the second air compressor motor respectively.
Technological scheme of the present invention, achieves staggered startup or the shutdown of two air compressor of locomotive group motors, decreases the impact to auxiliary circuit of locomotive, be conducive to the safe and stable operation of locomotive, reduce the replacement cycle of equipment easily damaged parts, reduce operating cost.
