Submersible pump installation safety inspection precautions

Submersible pump safety precautions after installation First, the safety precautions 1. Participate in the submersible pump installation or raise the well operators, should be safety training, work focus and work closely with. 2. When lifting (lifting) any equipment, sling, hanging chain and other hoisting tools should be strictly inspected to ensure compliance with requirements and undamaged to ensure the safety of personal and equipment. 3. Personnel operating electrical equipment must be trained to operate according to electrical safety practices. 4. In the submersible pump downhole components installed, raised wells must be cut off the power. Second, the well site safety and protection measures 1. Wellsite should be equipped with lightning protection devices 2. Electrical equipment (control cabinets, transformers, junction boxes) should be provided around the fence, and with "high voltage danger" sign 3. Ground cables should be passed Catheter buried in the ground, and equipped with cable channel, or overhead to prevent damage. 4. Well site should be reliable grounding device, control cabinet, transformer, junction box, wellhead should be reliably grounded. Third, the control cabinet (station) safety protection devices and precautions 1. Security devices 1). Control cabinet (station) are high pressure isolation zone 2) control cabinet (station) are grounded devices, and a grounding symbol 3 ) Control cabinet (station) access and wiring boxes are at the "high-pressure hazard" signs and text 2. Safety Precautions 1) control cabinet (station) operator must be a trained electrical technician. 2) The operator must observe the electrical safety rules. 3) control cabinet (station) must be grounded 4) troubleshooting must be blackout. Fourth, the transformer safety and precautions 1) alpine region with a transformer should be equipped with a snow cover to prevent transformer short circuit. 2) The transformer is equipped with grounding device, which must be grounded reliably. 3) The operation of the tap changer must be operated during a power outage. 4) When observing the transformer, we must pay attention to safety and keep a certain distance with live parts. It is not advisable to observe on the high voltage side to avoid electric shock accident. 5) When monitoring the oil surface temperature, keep a certain distance. Observe the temperature from the exposed part of the thermometer. Do not touch the thermometer with your hands. 6) Transformer installation and operation must be carried out by a trained electrician. V. Cable Safety Precautions 1) When submersible pump unit is in normal operation, the operator can not touch the cable and should keep certain distance with the cable. 2) After measuring the insulation resistance, discharge it to ground.
