Product knowledge
Selection of residual current action protector. Products that meet GB 6829 "General Requirements for Residual current action Protectors" and are certified by the China Electrical Products Certification Commission must be selected. Time-delay protectors similar to LJM (J) series power-saving and low sensitivity can be selected. The way of the protector device should comply with the national GB13955-2005 "Installation and operation of residual current action protection device" standard. The breaking time of the leakage protector, when the leakage current is rated leakage current, the operation time should not be greater than 0.s.
The inlet and outlet cables of the distribution box should be low-voltage cables, and the selection of cables should meet the technical requirements. For example, the distribution box of 30kVA and 50kVA transformers uses VV22-35×4 cables for the inlet line, and the branch outlet uses VLV22-35×4 cables of the same specification; The distribution box of 80kVA and 100kVA transformers uses VV22-50×4 and VV22-70×4 cables for incoming lines respectively, and VLV22-50×4 and VLV22-70×4 cables for branch outlets respectively. The cables are crimped with the copper and aluminum wiring nose and then connected with the wiring pile head in the distribution box with bolts.
