Distribution box into the selection of low voltage cable outlet, choose the cable should meet the technical requirements. For example 30kVA, 50kVA transformer distribution box into the line using VV22-35 × 4 cable splitter outlet using the same specifications VLV22-35 × 4 cable; 80kVA, 100kVA transformer, distribution box into the line were using VV22-50 × 4, VV22-70 × 4 cable outlet splitter were using VLV22-50 × 4, VLV22-70 × 4 cable, the cable crimping copper and aluminum lugs and then bolted connection with the distribution box trailer coupling . 2 The protection circuit prevents power distribution box external circuit failure. Choose smaller smart lack of protection explosion distribution box material, such as the choice of DA88CM-II phase motor protection module (Shanghai product) installed in low voltage power distribution box in order to prevent burn out the motor running phase. 2.3 Improved original wiring distribution box low-voltage capacitor group from its mounting position on the exchanges and contacts trailer coupling, into the low-pressure distribution box is connected between the line and meter gauge. To prevent the occurrence of the operation phase capacitor circuit failure or damage capacitors, resulting in inaccurate metering metering device. In addition, the model should be BSMJ capacitor selection series corrosion proof distribution box, in order to ensure quality and reliable components, safe operation. 2.4 If the new column with a radio rack explosion distribution box wiring, in the production of distribution box enclosure, optional 2 mm thick stainless steel plates, and appropriately scaled distribution box size (used in agricultural improvement projects The JP4-100 / 3W type, based on the original size of the cabinet width direction by about 100 mm, ie 680 mm to 780 mm original improved power distribution box dimensions for:. 1300 mm × 780 mm × 500 mm), in order to increase the shunt between qualifying, qualifying and the box housing electrical safety distance, it is a good electrician farming operation and maintenance and replacement of the fusible element, but also to the heat.
