Question 2: Distribution system diagram How to draw 1, into the line: C65H-C50/4P + VE100mA
According to the use of the view, the coefficient of demand Kx should be selected 1, the total load is fully open, the single-phase 63A is obviously not enough, so it should be selected three-phase Power Distribution.
The feeder can also choose a molded case circuit breaker, the price is slightly higher.
Additional leakage release function, release current 100mA according to half of the experience estimate.
Incoming cable, optional YJV-5*16.
2, outgoing line:
WL1~3 for 1 group, L1, L2, L3, *** with contactor KM1 were connected in series after the outgoing circuit breaker.
WL4~6 is 1 group, L1, L2, L3 (original labeling L4~6 is wrong), *** with contactor KM2, connected as above.
Contactor model, KM1 optional: 3TF46 or STF47; KM2 optional: 3TF32. coil 380V or 220V are available.
3, time control:
Select KG316T, you can set a number of hours, respectively, to control KM1, KM2.
4, line:
The original map WL1 ~ 3 can be; and WL4 ~ 6 theoretically conductor cross-section of 2.5mm2, if you want to avoid the line is long and the voltage drop is large can be retained 4mm2.
5, supplement:
It is recommended that this distribution box another manual - time control conversion;
If all the lamps and lanterns are opened and closed at the same time, it is recommended to choose a contactor access to the incoming line (after the circuit breaker, in front of the busbar), 3TF47.
The complete system diagram of the distribution box, but also need to draw the box (rectangular box), labeled with the grounding terminals and so on.
Question 3: How to draw the electrical schematic diagram The electrical symbols are arranged clearly according to a certain relationship, can meet the design requirements can be.
Question 4: Help ~ electrical system diagram how to draw a diagram like this
Your description does not say whether it is a single-phase or three-phase equipment, such as diagrams Single-phase on the 1P switch Three-phase on the 3P switch, according to the power of the equipment to calculate the current, select the switch and cable
Question 5: How to draw an electrical system diagram with CAD? With TZT Electrical 8.0 and CAD2006, that is, the next TZT Electrical 8.0 and then installed in the CAD directory, Chuan line. There are many strong and weak power and line symbols components.
Question 6: How to draw the distribution system diagram? First know the load, and then according to the load to determine the current, and then determine the switch, and then determine the wiring, piping This is a system diagram
Question 7: How to draw the distribution box system diagram? 10 points 1, into the line: C65H-C50/4P + VE100mA
According to the use, the coefficient of demand Kx should be selected 1, the total load is fully open, the single-phase 63A is obviously not enough, so it should be selected three-phase distribution.
Into the line device can also choose a molded case circuit breaker, the price is slightly higher.
Additional leakage release function, release current 100mA according to half of the empirical estimates.
Incoming cable, optional YJV-5*16.
2, outgoing line:
WL1~3 for 1 group, L1, L2, L3, *** with contactor KM1 were connected in series after the outgoing circuit breaker.
WL4~6 is 1 group, L1, L2, L3 (original labeling L4~6 is wrong), *** with contactor KM2, connected as above.
Contactor model, KM1 optional: 3TF46 or STF47; KM2 optional: 3TF32. coil 380V or 220V are available.
3, time control:
Select KG316T, you can set a number of hours, respectively, to control KM1, KM2.
4, line:
The original map WL1 ~ 3 can be; and WL4 ~ 6 theoretically conductor cross-section of 2.5mm2, if you want to avoid the line is long and the voltage drop is large can be retained 4mm2.
5, supplement:
It is recommended that this distribution box another manual - time control conversion;
If all the lamps and lanterns are opened and closed at the same time, it is recommended to choose a contactor access to the incoming line (after the circuit breaker, in front of the busbar), 3TF47.
The complete system diagram of the distribution box, but also need to draw the box (rectangular box), labeled with the grounding terminals and so on.
Question 8: How to draw the distribution system diagram? C45N-20A/1P (Schneider produced Melanchthon, disconnecting curve for the C-type, rated current 1-63 amps, 20 amps one-pole protection miniature circuit breaker), BVV-500 (2 * 4 + 1 * 1.5) WC / CEC (PVC-insulated copper-core wire, rated voltage of 500 volts, two four-square copper-core wire plus a 1.5-square grounding wire, the ground or the top of the wall concealed Laying.)
Question 9: How to draw the electrical system diagram and distribution diagram? Figure 20 points drawings are not there
Generally made of CAD blocks to complete the ah
Question 10: How to learn to draw the electrical system diagram Whether it is a system or a local, you just master the basic principles of electricity, coupled with the actual operation, I believe that you will soon be able to master.
