1. If strong electricity and weak electricity are to be separated by a long distance from the horizon walking line, the interval should generally exceed 30 cm to prevent disturbance and be interspersed with each other.
2. In order to facilitate the future line change, the PVC pipe must be cut off and straightened as much as possible. If you are worried that the installation floor will hit the pipeline in the future, you can make a good symbol, take some photos after the pipeline is arranged, and find it easily in the future.
3. If the interval of a wire is long and there are many bends, a wire bottom box can be added in the center of the PVC pipe to facilitate future maintenance and replacement.
4. PVC pipes must be able to bend more than 90 degrees, such pipes have high resistance, thick pipe walls and good quality.
5. All kinds of lines are not allowed to have joints in the PVC pipe, if the connection of the line should be left to check the port, the port must be able to open in the future, the line connection must be reliable, and solder should be used if necessary.
6. The electrical tape used to connect the wire needs to be wound tightly to reduce the oxidation of the air at the joint.
7. If it is a new house line transformation, it is best to separate the socket and lighting, if the second-hand house is expected to move as little as possible, sometimes a small number of sockets and lighting can not prevent it from being shared, try to choose a socket with low load.
8. Electrical appliances with large power should take special lines (air conditioners, etc.).
9. Some houses will have different levels of voltage due to special reasons, and the lines cannot be in the same tube.
10. The connection between the PVC pipe and the pipe should be glued firmly to prevent the water from entering the pipeline caused by watering during the sealing of the groove.
11. A household line will usually divide several groups of circuits in the distribution box according to demand, and high-power electrical appliances (air conditioners, etc.) are divided into a separate group, and the general sockets in the room are usually divided into several groups, and 10 to 15 sockets are generally connected to one road.
12. Many villa wires are three-phase, so balance should be considered when distributing socket lights in each room.
13. The switch height is generally 1.3-1.5 meters, the socket is 0.3-0.5 meters, the wall lamp is 1.8-2.0 meters, and the socket of the toilet is waterproof and convenient to use, generally 1.3-1.5 meters.
14. The connection between the socket and the wire should be in accordance with the principle of "left zero and right fire", that is, facing the socket, the left hole is the zero line, and the right hole is the front.
15. After the line is laid, the electrician uses the resistance shake meter to detect the insulation resistance, which should generally be more than 1 trillion ohms.

General parameter setting skills of inverter - Delixi inverter
1. Upper frequency (high speed) SEt - HSP and lower limit frequency (low speed) SEt - LSP
The upper frequency is the frequency corresponding to the *** large given, and the lower frequency is the frequency corresponding to the *** small given. The upper and lower limit frequencies are set to limit the speed of the motor, so as to satisfy the design.

Thermal calculation of linear regulator - Delixi
Thermal accounting requires information such as power loss, thermal resistance of the package, and ambient temperature. The power loss is the same as the power accounting, which is purely the value of the output input voltage difference multiplied by the input current. The thermal resistance should have a technical standard documented, and if it is not, it is necessary to ask the manufacturer. Basically...
