Precautions for Safety Inspection after Installation of Submersible Pump

Precautions for Safety Inspection after Installation of Submersible Pump
First, submersible pump electric control cabinet (station) safety protection devices and precautions
1. Safety protection device
1). Control cabinet (station) are high and low voltage isolation zone
2) control cabinet (station) are grounded devices, and a ground symbol
3) Control cabinet (station) into the outlet and junction box are "high-pressure danger" signs and text
2. Safety Precautions
1) The operator of the control cabinet (station) must be a trained electrical technician.
2) The operator must comply with the electrical safety procedures. In this case,
3) The control cabinet (station) must be reliably earthed
4) Troubleshooting A power failure must be performed.
4, submersible pump transformer safety and precautions
1) alpine region should be equipped with a snow cover transformer to prevent short-circuit caused by the transformer.
2) The transformer has a grounding device, the installation must be reliable grounding.
3) Operation of the on-load tap-changer The shift must be operated during a power failure.
4) observe the transformer, we must pay attention to safety, should be kept with the live parts of a certain distance, should not be observed in the high side, in order to avoid electric shock.
5) charged observation of oil surface temperature, should maintain a certain distance, from the exposed part of the thermometer observed temperature, shall not touch the thermometer.
6) The installation and operation of the transformer must be carried out by a trained electrician
5, diving cable safety precautions
1) Submersible pump unit work properly, the operator can not touch the cable, should keep a certain distance with the cable.
2) after measuring the insulation resistance, the response to discharge.
