Shanghai Shujia Electric Co., Ltd. is a professional manufacturer of instruments and meters. Here we introduce the use of high-current generators and precautions.
High current generator usage method:
1, according to the requirements of the commissioning, the riser and the test sample are connected and the power supply is connected.
2, according to the size of the current required by the sample to choose the current switch position, because the current transformer is not allowed to open, so the current switch can only be dialed to the "large" or "small" position, can not be placed centre position.
3, close the power supply, green light (if the green light is not bright, the regulator knob should be turned anti-clockwise until zero, until the green light), press the start button, the green light is red light, clockwise rotation regulator handle, Raise the current to the desired value.
4, turn the pressure regulator handle to zero counterclockwise, press the stop button, the red light is off the green light, the end of the test high current generator Note:
1. The test work shall not be less than two people. One person shall operate and one person shall supervise operations to ensure safety.
2. The housing must be grounded. Do not neglect safety precautions to prevent personal injury due to low voltage.
3. Proper conductor secondary to the test object conductor should not be too long, the cross-sectional area should be sufficient (current density can be considered 6-8A/mm) contact surface to be clean (can be fine gauze lighting), otherwise the joint heat, or even The current rises less than the rated value.
4. Before working, check that the power supply has sufficient capacity or the power cord is hot and the voltage drops to affect normal operation.
5. The work site should not have flammable materials. Temperature rise test should prepare enough fire extinguishing equipment.
6. Continuity (heating) test, on-site personnel should be on duty. And regularly check the source of rising equipment, wires, joints, fever, make a record. Due to changes in grid voltage, attention is paid to adjusting TD in order to maintain the rated test current.
7. The test work shall comply with the relevant provisions of the electrical safety work regulations and formulate practical safety measures.
