The time-limited protector comprises a start relay, a first time relay, a second time relay, a first small relay, a second small relay as well as an anti-explosion interface input circuit and an anti-explosion interface output circuit which are connected with each other and connected with the elements respectively. Through the time-limited protector of a start motor of an anti-explosion diesel engine for a mine provided by the invention, the problem of instability in practical application is effectively solved so as to ensure the normal operation of a locomotive.
Description
Technical field
The present invention relates to the anti-explosion diesel engine for mine technical field, relate in particular to a kind of anti-explosion diesel engine for mine actuating motor protector of prescribing a time limit.
Background technique
Diesel generating set is a kind of small power generation equipment, means that with diesel oil etc. be fuel, is the dynamic power machine that prime mover drives generator for electricity generation with the diesel engine.A whole set of unit generally is made up of with parts such as storage battery, protective gear, emergent cabinets diesel engine, generator, control box, fuel tank, starting and control.Integral body can be fixed on the basis, and use the location, also can be contained on the trailer, supplies to move to use.Diesel generating set belongs to discontinuous operation power generating equipment, if operation surpasses 12h continuously, its output power will be lower than rated power about 90%.Although the power of diesel generating set is lower; But because its volume is little, flexible, light, comprehensive; Be convenient to operation and maintenance; So be widely used in departments such as mine, railway, open-air building site, road traffic maintenance and factory, enterprise, hospital, as standby power supply or interim power supply.
In practical application; Because the existence of the undesired factor of mechanical factor and personnel operation, make actuating motor high frequency, the work of switching on for a long time, actuating motor at big electric current, for a long time, under the effect of high torque (HT); The field coil temperature sharply increases suddenly; Cause coil insulation to descend, acceleating winding is aging, until burning.
Therefore, need a urgent technical problem that solves to be exactly instantly: how can propose a kind of effective protective measure, to solve the problem that exists in the existing technology.
Summary of the invention
Technical problem to be solved by this invention provides a kind of anti-explosion diesel engine for mine actuating motor protector of prescribing a time limit, and effectively solves the unstable problem in the practical application, to guarantee the normal operation of locomotive.
In order to solve the problems of the technologies described above; The invention provides a kind of anti-explosion diesel engine for mine actuating motor protector of prescribing a time limit, comprising: starter relay, very first time relay, second time relay, first miniature relay, second miniature relay and the explosion-proof interface input circlult and the explosion-proof interface output circuit that interconnect and be connected with above-mentioned components and parts respectively.
Further, the model of the said very first time time relay and very first time relay is H3Y-2.
Further, said explosion-proof interface input circlult comprises time control circuit and power supply input circuit.
To sum up; The anti-explosion diesel engine for mine actuating motor provided by the invention protector of prescribing a time limit through the diesel engine starting motor protection controller, is controlled the starting time interval of actuating motor; Prevent machine abnormal condition and starting misoperation, play the protection actuating motor.
Through under abnormal condition,, the working life of actuating motor and battery pack can be prolonged reliably to the protective action of actuating motor.Promptly guarantee normal the use, can practice thrift investment again.
Description of drawings
Fig. 1 is the prescribe a time limit structural representation of protector of a kind of anti-explosion diesel engine for mine actuating motor of the present invention;
Fig. 2 is the anti-explosion diesel engine for mine actuating motor of the present invention structural representation of protector in practical application of prescribing a time limit.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is done further detailed explanation.
With reference to shown in Figure 1; Be a kind of anti-explosion diesel engine for mine actuating motor of the present invention protector of prescribing a time limit, comprise: starter relay 101, very first time relay 102, second time relay 103, first miniature relay 104, second miniature relay 105 and the explosion-proof interface input circlult 106 and the explosion-proof interface output circuit 107 that interconnect and be connected with above-mentioned components and parts respectively.
Referring to Fig. 2, saidly be the structural representation in the practical application, in the practical application, when switch starter pushed the starting retaining, it is electric that KA 1 coil gets, the ST1 starting time, begin to calculate regularly, regularly self-locking of KA2, when guaranteeing the switch starter return, ST1 maintains.
Starter relay gets electric,, the magnetic switch of connection actuating motor, on major loop, actuating motor coil and battery pack are connected, and actuating motor gets electric operation, drives generator work, starter-generator.
When the ST1 timing is set 8 seconds then, when ST1 time-delay normally closed interlock breaks off, cut off the starter relay path, can't carry out start-up function.ST1 time-delay normally open contact is closed, connects ST2 power-off protection electrical equipment at interval, is set at 40 seconds, the set time of delaying time, and ST2 time-delay normally-closed contact breaks off, the ST1 dead electricity, ST1 time-delay contact resets, the next starting of beginning, periodic control.
Scheme of the present invention is through letting explosion-proof actuating motor keep certain starting off time, and effectively the control coil temperature rise reaches the purpose of using the actuating motor life-span in critical field.
Particularly, flame proof actuating motor transient starting is in 8 seconds, and delay later in 8 seconds can be reset cyclic program in 40 seconds.Realize principle from it, mainly comprise: timing part, time-delay part and do-part, set chronometer time; Accomplish regularly part and time-delay part through relay; Accomplish execution by auxiliary reclay (high-power), connect the relay start loop, reach the purpose of safety circulation starting; Protect explosion-proof actuating motor, prolong the life-span of actuating motor.
More than a kind of anti-explosion diesel engine for mine actuating motor provided by the present invention protector of prescribing a time limit has been carried out detailed introduction; Used concrete example among this paper principle of the present invention and mode of execution are set forth, above embodiment's explanation just is used for helping to understand method of the present invention and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present invention, the part that on embodiment and application area, all can change, in sum, this description should not be construed as limitation of the present invention.
