In the home decoration, the most frequently encountered problem is the circuit transformation problem, the circuit problem is related to the life safety of the family. Indoor circuit wiring, multi-channel design should be adopted to make air-conditioning, kitchen, bathroom, living room, bedroom, computer and high-power electrical branch wiring; sockets and switches should be set separately, and each branch circuit should be installed with leakage Miniature circuit breaker switch with protection function. In addition, the strong electric line should be separated from the weak electric line by a certain distance, and the weak communication lines such as telephone communication cables, audio multimedia cables, and broadband network cables should be designed reasonably and meet the requirements of the specifications.
1. Before the wall and the ground open the slot, first use the cartridge to draw the line to determine the position. A plaster layer of about 15 mm should be left between the outside of the pipe and the wall to prevent cracking of the wall after plastering.
2. Without permission, it is not allowed to arbitrarily destroy or change public electrical facilities, such as lightning protection grounding, protective grounding, equipotential bonding, etc.
3. When the power line pipe is buried, it should be considered to maintain a distance of more than 500mm from the weak electric line, and the parallel distance between the electric pipe and the hot water pipe and the gas pipe is not less than 300mm.
4, the wall line pipe trend, as far as possible to reduce the turn, and to avoid the wall mirror, furniture and other things installed position, to prevent damage by electric hammer, nails.
5. If there is no special requirement, in the same house, the switch on the wall, between 1200-1500mm from the ground, 150-200mm from the door, the socket on the wall, about 300mm off the ground, the socket switch on the wall, On the same horizontal line, the height error is less than 8mm. When installed side by side, the height error is less than 1mm, and it is not blocked by sliding doors, furniture, etc.
6, a variety of strong electricity, weak electrical socket interface, Ning more do not lack, indoor bedside, should be set up power outlets and a telephone socket, near the computer desk, living room TV cabinet wall, should be set more than three power supplies Socket, and set the corresponding TV, telephone, multimedia, broadband network and other sockets.
7. The laying methods and requirements for weak electric lines such as TV, telephone, multimedia audio, broadband network, etc., are the same as the laying method of the power cable. The socket or cable box is installed side by side with the power socket, but the strong electric line and the weak electric line do not. Allow sharing of a set of tubes.
8. All the in-wall wires are buried with PVC flame-retardant tubes with a diameter of 16mm or more. The wires occupy the space of <40% of the pipe diameter and are connected with the bottom of the box, using special interface parts.
9. When using the conduit, the power conduit should be made to make a reasonable turning radius when passing through the ground. Pay special attention to the fact that under the ground, the casing must be used and the glue should be tightly connected. Before the ground is closed, the PVC sleeve must be protected. It is not allowed to have rupture damage; when laying floor tiles, PVC casing should be completely covered by cement mortar.
10. When wiring, the color of the phase line and the neutral line should be different; the color of the same residential phase line (L) should be uniform, for example, the phase line fire line, use yellow, or use green, or use red, neutral (N) Use light blue, protect the ground wire (PE) with yellow-green two-color line.
11. Before threading the line, you should put PVC glue directly on the head to avoid water ingress. When the power cord is passed through the pipe, the wire should be taken straight and then passed through the pipe. Do not pull or pull the pipe joint in the middle; in the weak current line, when the wire is threaded, do not use excessive force to avoid the wire breaking.
12, the power branch connector, should be connected in the socket box, switch box, lamp box, each connector wiring, should not exceed two, the line in the box, there should be appropriate margin.
13, the audio cable into and out of the wall, should be the bottom box. At the joint of the multi-core telephone line, the sheath tube is tightly wrapped with tape to prevent the telephone line from getting wet and causing crosstalk and other faults.
14, TV antenna wiring, must use a branch, and leave an inspection port.
15. The power cable in the tube must not have a connector. Do not expose the power cable to the ceiling or directly into the wall to ensure that the power cable can be pulled or replaced.
16, the wire connection is strong, the joint is not pulled, the dressing is tight, when the screw (nut) is connected, the wire has no insulation distance of not more than 3mm, the copper core wire is connected, the crimping or splicing method is applied, the length of the splicing is not Less than 5 laps, bare wires must be wrapped with waterproof tape, then wrapped with black tape, no damage such as insulation damage, and approved by inspection.
17. The wires, signal wires, telephone lines, etc. that are used for the pipe are tested to confirm whether there is a short circuit between the wires, a short circuit to the ground, a wire break, etc., and then confirm the correctness before performing the plugging.
18, single-phase two-hole socket wiring, facing the socket: left zero right phase (ie, the left side is zero line, the right side is the fire line), single-phase three-hole, directly above the ground. All single-phase sockets comply with the principle of “left zero right phase, grounding on topâ€.
19, socket, switch installation, to be firm, no gaps around, kitchen, bathroom and indoor and outdoor installation switches, should use a switch with a splash box.
20, air conditioning power supply, with 16A three-hole socket, all sockets below 1500mm in height, should be installed with a protective baffle socket, to avoid children's touch, the interior of the bathroom, should be used as a local equipotential bonding terminal, the socket is waterproof and splash-proof, And stay away from water. The lighting switch should be located outside the door, the mirror headlights, the bathroom heater, and the bathroom interior. The waterproof switch should be used.
21, in order to comfort and convenience of life, the bedroom should use dual control switch, kitchen power outlet, should be set side by side switch, control power on and off.
22. When the socket and switch panel are fixed, the matching screws should not be used instead of wood screws or gypsum board screws to avoid damage to the bottom box and the switch installation direction is the same.
23. The distribution box should be separately wired and supplied according to the different power of the indoor electrical equipment; for high-power household appliances, the socket should be installed separately. The wires in the distribution box should be arranged neatly, and the switches of the socket lighting should be separated. The crimping accessories are complete, the direction of the crimping wire should be correct, the circuit breaker wiring is firm, and the circuit breaker terminals must not be different. The wire of the wire diameter is crimped at the same end, and the distribution box is divided. To balance, each circuit should be marked.
24. After completion, submit a standard detailed circuit layout drawing.
The 80mm ultra-large paper warehouse is embedded with a thermal printer and supports a variety of communication interfaces, such as RS232, TTL, USB and other communication interfaces, allowing more users to accept it and making the product more friendly. It is widely used in large-scale self-service terminal equipment such as medical treatment and factories. Its appearance design is simple and supports the development of various systems. It does not need carbon ink, adopts thermal printing technology, and only needs thermal paper roll to print all kinds of content. It is an economical and fast printing.
