1.2Product Name:
ZKCintelligent charger
2.1ZKCseries of intelligentchargingmotor (hereinafter referred to as the charger) is suitable for charging the power supply device of the battery-type electric locomotive in the coal mine, underground and ground charging rooms where there is no explosion danger such as biogas (methane group) and coal dust.
2.2working conditions
2.2.1The altitude does not exceedover2000m.
2.2.2maximum ambient air temperature+40℃, minimum temperature-25℃.
2.2.3air relative humidity is the wettest monthly average maximum relative humiditynot greater90%, while the monthly average minimum temperature for the monthnot higher25℃.
2.2.4Applicable environment: It is suitable for the environment of non-explosive dangerous gas (methane group) and coal dust, and there is no conductive dust and steam enough to corrode metal and destroy insulation.
2.2.5place to prevent water and liquid intrusion.
2.2.6Where there is no severe impact and vibration, and its installation inclination is not large.in15.
3.1charger: three-phase ACflow50Hz 380V/660V.
3.2The output voltage and current of the charger are shown in the table above.
3.3grid voltageB =±5%.
3.4Charger volume:600 X400X920mm
3.5Charger weight:≤130kg
3.6has automatic phase sequence recognition function, no need to adjust the phase sequence.
3.7with soft start function, when soft startroom1.5S.
3.8toolshas overcurrent, overvoltage, phase failure and phase loss protection functions.
3.9has an automatic shutdown function. The microcomputer automatically calculates the functional relationship between the charging current, voltage and time. It automatically stops after being fully charged to prevent overcharge and undercharge.
3.10has a new battery initial charge function.
4The working principle of the charger (see electrical schematic diagram)
three-phase alternating current by open circuitQFContact via communicationKMto main transformerT1, transformerT1is added to the controllablesiliconVD1,VD3,VD5and Rectifier TwotubeVD2,VD4,VD6,three-phase half-controlled rectifier bridge circuit. The control principle is: the shunt installed on the output main circuitFLrandom sampling current signal is fed back to the current comparison terminal of the intelligent charger controller and compared with the current given value. When the current sampling signal is greater than the current given signal, the conduction angle of the thyristor moves backward, and the output voltage of the three-phase half-controlled rectifier bridge drops, that is, the output current drops. Similarly, when the current sampling signal is less than the current given signal, the conduction angle of the thyristor moves forward and the output voltage of the three-controlled rectifier bridge rises, that is, the output current rises to achieve the purpose of automatic constant current.With the extension of the charging time, the charging current gradually decreased30A, the charging time is controlled by a microcomputer. The microcomputer automatically calculates the functional relationship between the charging time, current and voltage, and issues a shutdown instruction after the full charge, which automatically stops, preventing overcharging and undercharging.
5.1This series of chargers are of cabinet structure. Its frame is formed by bending and welding steel plates. It has high mechanical strength and rigidity. The transformer is placed in the lower part, the rectifying part is installed in the middle part, the electrical mounting plate is installed in the upper part, and the instrument, indicator light and operation button are placed on the front part for easy operation and observation. The top part is equipped with a hanging tower for easy lifting and handling.
5.2charger is mainly composed of the following parts.
5.2.1Air switch, AC contactor, microcomputer controller, control transformer (only660Vinstallation).
5.2.2rectifier transformer.
5.2.3three-phase full-bridge rectifier components, over-voltage absorption components, fast fuses, shunts, etc.
6charging and maintenance methods
6.1charger arrives at the user, check whether all kinds of documents are complete, whether the product is complete, whether there is any damage, and whether the fasteners are loose.
6.2charger shall be provided by the user and shall be correctly wired according to the electrical schematic diagram. This series of chargers belong to constant voltage charging mode, so the charging voltage of a single battery is fixed. Therefore, after confirming that the power supply and external power supply of the charger are correct, it should also be determined whether the power supply device of the charged locomotive is matched with the charger, otherwise the charging current will be too large or too small, and the expected charging effect cannot be achieved.
6.3automatic charging (daily charging)
6.3.1Turn the current adjustment potentiometer knob counterclockwise"Zeroposition"location;
6.3.2Connect the AC input cable to the AC input terminal of the rear panel junction box;
6.3.3Connect the DC output cable wire to the DC output terminal of the rear panel terminal; (Notemeaning+,-polarity)
6.3.4will"Manual","frommovement"selector switch"frommovement"gear, close the three-phase power switch, the voltmeter should have instructions, the voltage value is the residual voltage of the battery, if there is no indication, should disconnect the three-phase power switch to find out the reason, confirm the normal before sending electricity;
6.3.5"Kaimovement"button to connect the AC contactor to the power;
6.3.6will"current regulation"the potentiometer knob slowly to clockwise rotation, then the ammeter should have instructions, adjust to the required charging current value can be;
6.3.7When the charging voltage reaches the rated voltage of the battery1.25times, the full light is on, indicating that the charging is complete.,8hours.
shall be restarted in case of power outage. If it is stopped midway, press the red stop button. If phase loss, overcurrent or overvoltage occurs, the charger will automatically stop and give an alarm. Press the red stop button and the alarm sound will be released.
6.4Manual charging (initial charging of new battery)
will"Manual","frommovement"selector switch"hand.movement"gear,chargerdoes not stop automatically, only throughover"Stopstop"the key to stop charging. Other operation steps are the same as automatic charging.
The initial charging of the new battery shall be carried out in two stages.
