db box electrical distribution Introduction:
With IEC60529 standard, LWHT series distribution box is attractive and durable, safe and reliable, which is widely used in various places such as factories, mansions, residences, shopping centers and so on.
We see the daily db box electrical distribution is according to the electrical wiring requirements of the switching equipment, measuring instruments, protective appliances and auxiliary equipment assembled in the closed or semi-closed metal cabinet or screen, constitute a low-voltage distribution device.
Waterproof distribution box believe that such an object in our life will not feel strange, so for such an object it has what unique advantages? For details, see the following introduction:
Waterproof distribution box has dustproof, prevention, acid resistance, alkali resistance, appearance, waterproof distribution box has beautiful, stable quality, complete insulation is not conductive, impact resistance is not deformation and other characteristics.
Db Box Electrical Distribution box leakage inspection process and precautions
Use tool: multimeter
Inspection preparation: Before using a multimeter to detect the leakage of power distribution cabinets or distribution boxes, we must first look at what faults appear in the distribution box and what are the obvious characteristics; secondly, observe whether there are intuitive fault points from the surface, and then proceed. Next check.
Detection process:
1. First disconnect the main isolation switch of our power supply line, and turn off the electrical load of all loads, such as unplugging the refrigerator, disconnecting the water pump switch, etc. 2. Put the gear of the digital multimeter on the 200M stop of the ohm gear, place one test lead on one of the two lead wires on the load side, and the other test lead touches the wall, try to touch the ground wire or temporarily ground String. After the number displayed on the multimeter is stable, the insulation resistance value of the main circuit is read. If the insulation resistance value is less than 0.5 megohm, then there is a problem with the main circuit. If the insulation resistance is above 0.5 megohm, it can be ruled out There is a problem with the main line. Use the same method to measure another wire, and also check the value to see if there is a problem with the main circuit. 3. Check the insulation resistance of the shunt and each electrical appliance, and use the same method to check one by one until the fault point is found.
