Utility model content
The purpose of this utility model is to provide a kind of silicon rectifier draw-gear be applied on mine locomotive, has overcurrent, short circuit, open circuit, under-voltage, open-phase protection, increases that time delay is powered, Delayed power failure device and earthing device.
For achieving the above object, the utility model is achieved through the following technical solutions:
The silicon rectifier draw-gear be applied on mine locomotive described in the utility model, comprise three-phase breaker, first relay, second relay and the time relay, A.C. contactor comprises main contacts and the auxiliary contact of ac contactor coil and A.C. contactor, first relay comprises the first relay coil and the first relay contact, second relay comprises the second relay coil and the second relay contact, three-phase breaker is electrically connected A.C. contactor main contacts, A.C. contactor main contacts is electrically connected transformer, transformer is electrically connected silicon rectifier, silicon rectifier is electrically connected current relay, ac contactor coil is connected with current relay normally-closed contact, connect with ac contactor coil after first relay normally open contact and the second relay normally open contact parallel connection, second relay coil is connected with time relay normally opened contact, time relay coil and the parallel connection of the first relay, current relay normally opened contact is connected with buzzer, indicator light and A.C. contactor are often driven auxiliary contact and are connected.When breaking down in whole circuit, automatic shutdown circuit, time relay trigger, within the scope of time regulatable 0s-5940s, device can power transmission automatically.
Button and normally closed button are often driven in ac contactor coil series connection, often drive button in parallel with the first relay normally open auxiliary contact and the second relay normally open auxiliary contact, for the start-stop of control circuit.
The utility model compared with prior art, has following beneficial effect:
When there is the operating modes such as overcurrent, short circuit, open circuit, under-voltage, phase shortage in the line; silicon rectifier draw-gear can play a protective role; reduce the loss of electric energy during device zero load; when breaking down in whole circuit; silicon rectifier draw-gear can auto-breaking reporting to the police, and pending fault can power transmission automatically after getting rid of.
Accompanying drawing explanation
Fig. 1 is the utility model silicon rectifier draw-gear electric control circuit schematic diagram.
Embodiment
Below in conjunction with embodiment, the utility model is further described.
As shown in the figure, silicon rectifier device described in the utility model, comprise three-phase breaker QF, first relay K M1, second relay K M2 and time relay KT, A.C. contactor KM comprises main contacts and the auxiliary contact of ac contactor coil and A.C. contactor, first relay K M1 comprises the first relay coil and the first relay contact, second relay K M2 comprises the second relay coil and the second relay contact, three-phase breaker QF is electrically connected A.C. contactor KM main contacts, A.C. contactor KM main contacts is electrically connected transformer ZSL, three-phase transformer ZSL is electrically connected silicon rectifier ZP, silicon rectifier ZP is electrically connected current relay JL, A.C. contactor KM coil is connected with current relay JL normally-closed contact, with A.C. contactor KM coils connected in series after first relay K M1 normally opened contact and the second relay K M2 normally opened contact parallel connection, second relay K M2 coil is connected with time relay KT normally opened contact, time relay KT coil and the first relay K M1 parallel connection, current relay JL normally opened contact is connected with buzzer HA, indicator light HG and A.C. contactor KM often drive auxiliary contact and connect.A.C. contactor KM coils connected in series often leaves button SB2 and normally closed button SB1, often open button SB2 and the first relay K M1 often open auxiliary contact and the second relay K M2 often to drive auxiliary contact in parallel.
After equipment access 380V or 660V three-phase alternating-current supply, close three-phase breaker QF, electric current is successively by A.C. contactor KM and three-phase transformer ZSL, three-phase transformer ZSL connects silicon rectifier device ZP, electric current is after silicon rectifier device ZP rectification, direct current is exported, for mine locomotive provides power through the current relay JL of series connection.Rotate mains switch SA1, it is bright that power supply connects instruction HW lamp, when Non-follow control, presses start button SB2, A.C. contactor KM obtains electric, A.C. contactor KM main contacts closes, and current relay JL obtains electric, and simultaneously A.C. contactor KM often leaves auxiliary contact and closes, first relay K M1 obtains electric, A.C. contactor KM coil and the first relay K M1 normally opened contact form self-locking, and device will enter operating state, and mine locomotive starts.When mine locomotive is out of service, press stop button SB1, AC relay KM dead electricity, circuit cuts off automatically, and silicon rectifier draw-gear also quits work automatically.When circuit is switched to automatic control; turning knob SA2; time relay KT coil obtains electric; the coils connected in series of time relay delay cut-off contact and the second relay K M2; when there is the operating modes such as overcurrent, short circuit, open circuit, under-voltage, phase shortage, device can be protected automatically, power alarm; within the scope of time regulatable 0 ~ 5940s, device can power transmission automatically.
In sum, silicon rectifier draw-gear described in the utility model, improves mine locomotive fail safe, simultaneously saves energy again.
