As an important part of distribution equipment, the distribution box produced by distribution box manufacturers is also very important for its transformation. In order to adapt to and facilitate the safety of electricity use, the distribution box is becoming more and more important. All aspects of the distribution box must be improved. To improve the distribution box, first start from the following aspects:

1. For distribution box with distribution transformer capacity of 100kV × 16 × 11a and above, temperature control relay and axial flow fan shall be installed on the box on the left side above the control electrical panel at the side wall of the cooling window in the box, so that when the box reaches a certain temperature, the exhaust fan can be automatically started and the heat can be forced out.

2. The protection circuit is adopted to prevent the external circuit failure when the distribution box is powered. For example, da88cm-ii motor phase loss protection module can be installed in the distribution box to prevent the motor from burning due to low-voltage phase loss operation.

3. Improve the wiring mode of the low-voltage capacitor bank of the original distribution box, and change its installation position from the pile head on the AC contactor to the connection between the low-voltage incoming line of the distribution box and the meter. To prevent inaccurate measurement of the metering device due to phase failure of the capacitor circuit or damage of the capacitor during operation. In addition, the type of capacitor shall be bsmj series products to ensure reliable and safe operation of components.

4. How to achieve the best performance of the distribution box? If a new distribution frame on the column is added, the shell of the distribution box can be made of 2 mm thick stainless steel plate, and the size of the distribution box can be appropriately enlarged according to the proportion (on the basis of jp4-100 / 3W type used in the agricultural reform project, the size of the original box in the width direction is increased by about 100 mm.
