In recent years, accompanied by the completion acceptance of the rural power grid refreshing project, the rural electricity tariff has dropped, plus the price of diesel and gasoline has risen again and again. Pumps, peanut shellers, threshers, breakage machines, and rice mills in agricultural machinery have risen. The use of electrical power as a machine has become more and more important. In the process of using these electric agricultural implements, people do not pay attention to the condition of the inspection and the voltage value of the power supply before the start, which causes personal injury and death and the destruction of agricultural electrical power. How to check the agricultural idea before starting it has become a concern for users of electric motors. The common sense in this area is as follows:
Root debris. Dirt on the cut-off motor, all around debris, and flammable and explosive materials piled up.
Before starting, it is necessary to check whether the agricultural electric bullets are agile, with or without friction, jamming, stringing and abnormal sound. Whether the homework machinery is blocked or not, and whether the belt is adjacent is excellent, in particular, the drive belt must not be too tight or too loose. The bolts and pins of the coupling should be complete and firm, and must not be loosened.
Check whether the line voltage is normal before start-up. If it is too high or too low, it is not suitable to start. It should not cross the rated voltage value +10 %ï½ž-5 % to start.
When starting agricultural power, it should generally be empty or lightly loaded. No person should be nearby. The person operating the switch should stand on one side to prevent arc burns. The use of a double-switching star triangle to start the process must comply with the operating procedures.
After closing, if the power does not turn or the moving shell is slow and the sound is not normal, it shall be quickly checked for power failure, and after the fault is found, it shall be started again.
Multiple motor starting operations. It should be started from a small station to a small station, and several stations should not be started at the same time.
Limit the number of starts. When a power supply is started multiple times, it should keep the proper distance between two start-ups to prevent overheating. The number of continuous starts must not exceed 3 to 5 times. If it is started shortly after work, it should not cross twice. , otherwise it is easy to burn the motor.
Reverse measures. When the start-up reversal occurs, the system immediately shuts down. After the two-phase power lines are exchanged, the reversal can be forwarded.
Newly installed or permanently deactivated electrical power should also perform the following inspections:
Whether the basic idea of â€‹â€‹electric power is stable, whether the bolts are tightened, whether the bearings are short of oil, and whether electric wiring is suitable or not, and whether the insulation resistance is passed is measured by a â€œrocking tableâ€.
Whether the fuse is suitable or not, the wiring of the starting equipment is correct, whether the starting assembly is agile, whether there is a stuck phenomenon, and whether the contact of the contact is excellent.
Whether the metal housing of the agricultural product and starting equipment is reliable or grounded. According to China's "Low Voltage User Electrical Installation Regulations", the rural power equipment should adopt protective grounding.
