Wecan series 1.5-3.0t electric counterweight forklift battery

When we can't distinguish the polarity of the forklift battery, we must strictly check it to connect it. Generally, the positive and negative signs on the battery pack have obvious marks, but some of the marks in domestic and foreign factories are not clear or fuzzy, so it is necessary to measure the correct positive and negative polarity before installation. Otherwise, it is possible to burn down the vehicle dashboard. The forklift battery is expensive and must be strictly observed before use The instruction manual can also be distinguished by ampere rule, which is also called right hand helix rule. It is a rule indicating the relationship between current and magnetic induction line direction of magnetic field excited by current. Principle hold the solenoid with your right hand, and let the four fingers bend and be consistent with the current direction in the solenoid, then the end pointed by the thumb finger is the N-pole of the solenoid. In the experimental steps, the solenoid, resistance, switch and power supply are connected with wires according to the device shown in the figure above, Place a small magnetic needle with known magnetic pole at one end of the solenoid, close the switch and observe the direction of N pole when the small magnetic needle is still. According to the law of interaction between magnetic poles, the polarity of both ends of solenoid can be judged (a end is S pole, B end is n pole). Then according to ampere rule, the direction of current in the coil can be determined (the current direction of front solenoid is downward), and the current is from the power supply The positive electrode flows out and flows in from the negative pole of the power supply (C-terminal is positive pole, d-terminal is negative pole).
