pvc db 6 way Introduction:
This is classical distribution box .which can be equipped with various modular electrics for the function of terminal power distribution.
It is widely used in low voltage distribution networks for power supplying of consumers and commercial buildings.
The materials used in the manufacture of low-voltage cable branch boxes are based on pei Xiuzhi's composite materials. The main configuration of the box is divided into ABS engineering plastic, POLYcarbonate PC data, DMC, SMC 4 eggplant data injection, limit. The dental composite is composed of two parts: air-polyester resin. Enhanced data (PC, SMC) is also known as transparent PC data, fiber reinforced polyester data. PC data, fiber reinforced unsaturated polyester is based on unsaturated polyester resin composite materials.
Waterproof distribution box pvc db 6 way Qualification:
The waterproof distribution box manufacturer will analyze you today to determine whether a distribution box is qualified.
Must have 3C logo, product appearance intact, no damage.
Complete data, distribution box or distribution box system diagram should include schematic diagram, wiring diagram, etc. (William Shakespeare, Windows, wiring diagram, wiring diagram, wiring diagram, wiring diagram, wiring diagram, wiring diagram, wiring diagram, wiring diagram) The components of the distribution box or distribution box must have a qualification certificate, operation manual, etc. Factory inspection report distribution box packing.
By comparing the drawing with the finished product, you can see whether the drawing and the customer's requirements are correct.
Connection mode and wiring diagram of dual power distribution box Pvc Db 6 Way
As long as the two groups of power supply are respectively connected to the two air switches power supply line side, the load is connected to the AC contactor line end.
Before installing cables, check the appearance of the distribution box, verify the correctness of the cables, and check the insulation, connection and grounding of each component.
After inspection, use a three-phase 5 amp switch as the test power switch, and carry out live simulation test on the distribution box to ensure that the installation can basically meet the requirements.
When connecting two groups of power supplies, determine which power supply is preferred. Connect the preferred power supply to the side without time delay, and connect the standby power supply to the side with action after time delay.
When the lower end of the AC contactor is not connected, connect the two power supplies to each other to ensure normal power supply when either power supply is delivered.
After the connection is completed, the test of power switching should be carried out: power is delivered to one group of power supplies respectively, and the switch is turned to the main power supply, backup power supply, automatic and other positions at the same time to check the switching condition of the two contactors, as well as the synchronous closing condition of each phase and the connection condition of contacts.
If you want to check the load condition, you must also send the rated load for inspection. In the inspection of live equipment, it is necessary to abide by the safe operation rules to ensure the safety of the implementation process.
