Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that all the directional indicators (such as up, down, left, right, front, and rear … …) in the embodiment of the present invention are only used to explain the relative position relationship between the components, the movement situation, etc. in a specific posture (as shown in the drawing), and if the specific posture is changed, the directional indicator is changed accordingly.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In addition, technical solutions between various embodiments may be combined with each other, but must be realized by a person skilled in the art, and when the technical solutions are contradictory or cannot be realized, such a combination should not be considered to exist, and is not within the protection scope of the present invention.
In the current circuit wiring of home decoration and tooling industry, wiring is usually distinguished according to different purposes of electric equipment, generally, three-house households are required to be divided into 6 groups to 8 groups of circuits from a distribution box, the circuits are connected from a unified distribution box, and then the circuits are respectively led to preset electric units such as electric terminals or sockets and the like needing to be connected with electricity.
However, this wiring scheme has four problems:
1. the protection range is wide. When any one electric appliance terminal has an electric leakage fault, the main switch can be tripped, so that the whole household circuit is completely powered off, and great power utilization inconvenience is caused;
2. the problem of the missing of the protection function. Because the leakage protection of the distribution box does not have the overload protection function, and the air switch only aims at severe overload, when the temperature of a home is moderate and overloaded (the power consumption exceeds the load limit of a line within 10 percent), the leakage protection and the air switch do not execute breaking protection, and the accumulated heat of the line with the temperature and overload is more and more along with the accumulation of time, so that the fire accident is easily caused;
3. the structure is tedious, wasting material and working hours. The lines are required to be pulled out of the distribution box all the way and all the way, so that the number of the lines pulled out of the distribution box is too large, the use amount of materials is increased, and the construction period is prolonged. With the development of economy and the continuous improvement of the living standard of people, more and more household appliances can enter the family, if the traditional method for distinguishing the wiring by using the electric equipment is continuously used, the structure of the household appliance is more and more redundant, and the consumption of materials and labor is more and more.
4. The circuit is inconvenient to overhaul. When the existing wiring method has a short-circuit fault, the problem of which line is in fault can be judged by shunt tripping, and then the maintenance work is gradually carried out; however, if the leakage fault occurs, the leakage protector as the main switch is directly tripped, and the place where the leakage occurs cannot be judged at all, so that the corresponding maintenance work becomes complicated.
In view of the above problems, the present invention provides an indoor circuit wiring system, referring to fig. 1, the indoor including a plurality of areas each including at least one power consuming unit, the indoor circuit wiring system including: the power distribution equipment comprises power distribution equipment 20 and at least one group of power transmission main lines, wherein each group of power transmission main lines is provided with an input end and an output end, the input end of each group of power transmission main lines is connected with a wire outlet end of the power distribution equipment 20, and the output end of each group of power transmission main lines is used for being connected with power utilization units in at least one region; and the total power consumption of the power consumption units connected with the output end of each group of power transmission main lines is less than or equal to the preset load power.
The indoor circuit wiring system is suitable for indoor wiring scenes such as home decoration, tools and the like. The configuration of the wiring box 20 is prior art and will not be described in detail herein.
Referring to fig. 1, the room includes a plurality of areas, and the areas may be divided into a plurality of independent areas such as an area 1, an area 2, and an area 3 according to walls, or may be divided according to functions, for example, an area 4 is a living room area and a restaurant area, an area 2 is a study room area, and an area 1 is a main lying area.
It can be understood that, in the home decoration or the tooling, the types and the number of the electric devices which may be needed in each area can be planned according to the functions of each area at the beginning of decoration, each area comprises at least one electric unit, and the electric unit comprises electric devices such as a lamp, a television, an air conditioner and a refrigerator, and can also comprise a socket. For example, 1 lighting fixture, 1 air conditioner, 1 television and 4 sockets (the electrical equipment that the socket may be plugged into may be equipment such as a desk lamp, a mobile phone, an electric fan) need to be used in area 1 (bedroom area), then based on the plan, the total electricity consumption of all the electrical units that may be included in area 1 may be calculated, the electricity consumption of the socket is calculated according to the electricity consumption of the electrical equipment that may be plugged into the socket to take electricity, and similarly, the total electricity consumption of the electrical units in all the areas may be calculated in this way, and the total electricity consumption of the electrical units is the total rated power of all the electrical units involved in calculation or the total rated current amount corresponding to the total rated power.
When the total power consumption is calculated, the service conditions of the sockets can be reasonably estimated based on the use habits and the requirements of users, and the calculation is performed according to the service conditions, for example, although 4 sockets are reserved in an area 1 (bedroom area), the use habits of the users can be that three power utilization devices are plugged simultaneously, when the total power consumption is calculated, the calculation can be performed according to the plugging time of the three sockets, but in consideration of power utilization safety, when the total power consumption is calculated, the calculation can be performed according to the condition that all the sockets are plugged with power utilization units.
The output end of each group of power transmission main lines is used for being connected with power utilization units in at least one region; the total power consumption of the power consumption units connected with the output end of each group of power transmission main lines is less than or equal to the preset load power, all areas can be divided into different sections according to the preset load power, and then the corresponding power consumption units in one section are connected with the output end of one group of power transmission main lines so as to supply power to the power consumption units in the corresponding section through the power transmission main lines.
The method for dividing all the areas into different areas according to the preset load capacity can be divided by adopting an indoor circuit wiring method, wherein the indoor circuit wiring method comprises the following steps: calculating the total power consumption of the power utilization units in each area, and calculating the area power consumption of each area according to the total power consumption; determining the position relation among the regions, and determining a target region meeting a preset fragment region construction rule according to the position relation; if a plurality of target areas exist, calculating the sum of the area electricity consumption corresponding to each target area; if the sum is smaller than or equal to the preset load electric quantity, taking each target area as a block area; each parcel is connected to distribution equipment via a set of power mains to supply electricity consuming units within the parcel via the power mains.
The calculating the area power consumption of each area according to the total power consumption may be directly taking the total power consumption of the electric units in each area as the area power consumption of the corresponding area, for example, if the total power consumption of the area 1 (bedroom area) is 20A (or 4400W), then the area power consumption of the area is 20A (or 4400W); a certain percentage of the total power consumption of the electricity utilization units in each area (the value can be estimated according to an empirical summary or an experimental theory, etc.) can be added as the pre-increased power consumption, and the total value is taken as the area power consumption of each area, for example, the total power consumption of the area 1 (bedroom area) is 20A (or 4400W), on the basis of which 20% of the pre-increased power consumption is reserved, then the area power consumption of the area is multiplied by 120%, that is, 20A × 120% — 24A (or 4400W × 120% — 5280W), and the other areas are the same; respectively estimating according to the condition that the future electric equipment is possibly newly added in each area to reserve the percentage of the pre-increased electric quantity, for example, the total electric quantity used in the area 1 (bedroom area) is 20A (or 4400W), 20% of the pre-increased electric quantity is reserved, and then the area electric quantity used in the area is 24A (or 5280W); the total power consumption of the area 5 (kitchen area) is 20A (or 4400W), 30% of reserved power consumption needs to be reserved, and then the area power consumption of the area is 26A (or 5720W).
It should be noted that, during actual wiring, each area has a total incoming line end, and the commercial power accessed from the distribution box supplies power to each power utilization unit through the total incoming line end. For convenience of construction and material saving, when determining the positional relationship between the regions, it specifically refers to whether the regions are adjacent to each other, and the positional relationship between the total incoming line ends of the regions.
The preset fragment construction rule may be divided according to whether the positions of the regions are adjacent, referring to fig. 1, for example, if the regions 5 and 6 are adjacent in position, then the regions 5 and 6 are respectively used as target regions of a fragment; the total incoming line ends may be divided according to the distance between the total incoming line ends, for example, the total incoming line end of the region 7 is closest to the total incoming line end of the region 2, so that the region 7 and the region 2 may be target regions of one segment; it is also possible to comprehensively consider the area positions and the total incoming line end positions, for example, one area of each of the area 1, the area 2, and the area 7 as a target area.
The area 4 is a living room area and a restaurant area, and when the target area is determined, the living room area and the restaurant area may be divided into the target area of one parcel, or may be divided into target areas of different parcels separately from different areas. The area 3 is a balcony area, but in practical applications, there may be only one washing machine and one lighting lamp on a balcony, and therefore, the balcony area and the living room area may be divided into one target area, and of course, there may be two target areas.
The preset load capacity can be set according to experimental data or empirical summary, such as 20A (or 4400W), 24A (or 5280W), 30A (or 6600W), 36A (or 7920W), and the like, and the setting of the load capacity is more considered in the bearing capacity of the transmission line.
If a plurality of target areas exist and the sum of the area electricity consumption corresponding to each target area is less than or equal to the preset load electricity, taking each target area as a parcel; for example, if the preset load capacity is 24A (or 5280W), the area power consumption of the area 5 is 13.6A (3000W), the area power consumption of the area 6 is 10A (2200W), and the sum of the preset load capacity and the area power consumption is smaller than 24A (or 5280W), the area 5 and the area 6 can be regarded as one parcel.
And if the sum is larger than the preset load electric quantity, calculating a difference value between the sum and the preset load electric quantity, screening each target area according to the difference value, and taking the screened target area as a fragment area. The specific manner of screening the target areas according to the difference may be that the target areas are screened according to the difference and the area power consumption of the target areas.
For example, the area 4, the area 5, and the area 6 are also adjacent areas and may be used as target areas of one parcel, but the area electricity consumption of the area 4 is 18A (39600W), the area electricity consumption of the area 5 is 13A (2860W), and the area electricity consumption of the area 6 is 10A (2200W), the sum of the three area electricity consumptions is 41A (9020W) which is greater than the preset load electricity amount 24A (or 5280W), the difference is calculated to be 17A, and the area 4 is suitably divided separately in consideration of the difference and the utilization rate of the wire rod, so that the target areas after screening are the area 5 and the area 6, and the area 5 and the area 6 are used as one parcel. Of course, if the difference between the sum of the areas 5 and 6 and the preset charge carrying capacity is large after the area 4 is divided, the sum may be calculated again by using the other areas together with the areas 5 and 6 as the target area of the segment, and the segment may be divided.
It should be noted that, if the area 4 has a large electricity consumption and is not suitable to be divided into one section together with other areas, the area 4 may be a single area as one section.
The power transmission main line is a power transmission line, if the power transmission main line is only connected with a target area, the power consumption of the area is less than or equal to the line diameter load current limit of the power transmission main line; if the power transmission main line is connected with a plurality of target areas at the same time, the total power consumption of the administered target areas is less than or equal to the line diameter load current limit of the power transmission main line. The selection of the power transmission main line specifically needs to be selected according to the setting of the preset load capacity, for example, when the preset load capacity is set to be 30A (or 6600W) or 36A (or 7920W), the power transmission main line should select a power transmission line with a cross-sectional area of 6 square millimeters in consideration of the carrying capacity of the power transmission line; when the preset load capacity is set to be 20A (or 4400W) or 24A (or 5280W), the cross-sectional area of the power transmission main line is at least 4 square millimeters, and a power transmission line with 4 square millimeters is selected for economic consideration.
In this embodiment, according to the fact that the power consumption of the district is less than or equal to the preset load capacity, the whole indoor area is divided into one or a plurality of independent districts, then the divided one or a plurality of independent districts are respectively attributed and communicated to the scope under the jurisdiction of a group of main lines, and a root system expansion structure is formed, wherein the distribution box is provided with a group of main lines communicated with one independent district under the jurisdiction, or a plurality of groups of main lines are respectively communicated with a plurality of independent districts under the jurisdiction. Therefore, the circuit structure of the circuit wiring system is simplified, and referring to fig. 1, three rooms only need to be divided into a group of main lines a, a group of main lines b and a group of main lines c, and 3 groups of main circuits. By dividing each region into the sub-regions and independently supplying power to each sub-region through the power transmission main line, the circuit structure of the circuit wiring system is simplified, materials and working hours are greatly saved, and meanwhile, line faults can be conveniently overhauled.
Further, the indoor circuit wiring system further comprises a plurality of circuit breakers 10, each region is provided with one circuit breaker 10, the incoming line end of each circuit breaker 10 is connected with the output end of the corresponding power transmission main line of the region where the circuit breaker 10 is located, and the outgoing line end of each circuit breaker 10 is connected with the power utilization unit of the region where the circuit breaker 10 is located.
The circuit breaker 10 is used for outputting a power supply current when the connected power utilization unit works normally; when the connected power consumption unit is overloaded, short-circuited or leaked, the output of the power supply current is stopped, that is, the circuit breaker 10 has the functions of short-circuit protection, leakage protection and overload protection. The regional power consumption of each region is less than or equal to the rated power consumption of the circuit breaker 10, the power transmission main lines carry out power supply transmission by connecting the incoming line ends of the circuit breaker 10, each group of power transmission main lines are responsible for the total amount transmission of power supplies of all regions under the jurisdiction of a single wafer region, the power transmission main lines are not directly connected with all power consumption units in the region but connected with the incoming line ends of the circuit breakers 10 in all regions, the power consumption units in the corresponding regions are connected by the outgoing line ends of the circuit breakers after the current is combed by the circuit breakers 10, and therefore the vertical structure of the circuit breakers, the power transmission main lines and the power consumption units in the corresponding regions is formed.
After the power transmission main line circuit is connected with the circuit breaker 10, when each power consumption unit connected from the outlet end of the circuit breaker 10 has short circuit, electric leakage or overload fault, the circuit breaker 10 stops outputting power supply current to the connected power consumption unit, and the condition of entering power-off protection in the area is ensured. However, if no circuit fault such as short circuit, electric leakage or overload occurs in other areas (if any) under the same power transmission main line, the circuit breaker in the area without the fault normally operates, and the power utilization unit with the connected outlet end normally utilizes power. Because the circuit breakers installed in each area are only responsible for the power consumption management of the power consumption units connected out of the outlet terminals, the circuit flow on the power transmission main line connected to the inlet terminals cannot be acted, namely if the power transmission main line is connected with a plurality of subordinate areas, if one area has a short circuit, leakage or overload fault, the circuit breakers installed in the fault area can independently execute breaking protection, and the circuit breakers in other fault-free areas subordinate to the group of power transmission main lines normally continue to supply power. Therefore, according to the scheme, each area where the circuit breaker 10 is installed can be used as an independent area, and independent power utilization management and independent circuit fault management in each independent area range can be achieved.
Further, when the number of the regions corresponding to the output end of the power transmission main line is greater than 1, the line inlet ends of the circuit breakers corresponding to the regions closest to the power distribution equipment are connected with the output end of the power transmission main line, and the line inlet ends of the other circuit breakers are sequentially connected with the line inlet end of the circuit breaker at the previous stage according to the sequence from the near to the far of the corresponding regions and the power distribution equipment.
When a group of wafer regions only corresponds to one target region, the incoming line end of the circuit breaker 10 in the target region is connected with the distribution box through the power transmission main line. When the number of the target areas corresponding to one group of the areas is greater than 1, that is, when there are two or more target areas, it is preferable to connect the target areas with the incoming lines of the distribution box according to the principle of proximity, that is, the target area closest to the distribution box is used as a first connection sequence, the incoming line end of the target area is connected with the distribution box through the group of the power transmission main lines, and then, a group of the power transmission main lines is connected in parallel from the incoming line end of the breaker 10 to the incoming line end of the next breaker 10, and so on. Referring to fig. 1, for example, since the distance between the zone 5 and the distribution box is shorter than that between the zone 6, the order of connection of the circuit breakers 10 in the zone 5 is the first stage, the zone 6 is the second stage, and the connection method of the transmission main line is: after the power transmission main line is connected with the incoming line end of the circuit breaker 10 installed in the area 5, a group of power transmission main lines are connected in parallel from the incoming line end of the circuit breaker 10 to the incoming line end of the circuit breaker 10 installed in the area 6, and the like.
It should be noted that, when the incoming line ends of the other circuit breakers 10 are sequentially connected to the incoming line end of the previous circuit breaker 10 according to the connection order, a power transmission main line may not be used, as long as the carrying capacity of the power transmission line can satisfy the area power consumption of the area corresponding to the next circuit breaker 10.
In this embodiment, when two or more target areas are under the jurisdiction of a group of power transmission main lines, the incoming line ends of the circuit breakers 10 in each target area can be connected by sampling, which not only can save wires and reduce construction cost, but also can make the line structure clear and simple.
Furthermore, the indoor circuit wiring system further comprises at least one circuit breaker, wherein the wire inlet end of the circuit breaker is correspondingly connected to the output end of the power transmission main line, and the wire outlet end of the circuit breaker is respectively connected with the power utilization units corresponding to the power transmission main line.
In this embodiment, each zone is provided with one breaker, all the electricity utilization units in the zone are managed by the breaker, and when each electricity utilization unit connected to the outlet terminal has a short circuit, an electric leakage or an overload fault, the breaker stops outputting a supply current to all the electricity utilization units in the zone, so that the condition that the zone enters a power-off protection state is ensured, and other zones still operate independently. Based on this, the independent operation of each slice area can be realized in the scheme.
It should be noted that, during actual wiring, according to different actual situations, one circuit breaker may be separately arranged in one zone, or one circuit breaker may be separately arranged in a target area in the zone, so that the arrangement may be flexible.
Further, the circuit breaker is used for outputting a power supply current when the connected power utilization unit works normally; and when the connected power utilization unit is overloaded, short-circuited or leaked, the power supply current is stopped to be output.
In this embodiment, the overload is mild overload, which means that the circuit is overloaded but does not meet the standard of breaking protection of a common circuit breaker, and if the mild overload continues for a long time, temperature rise is gradually accumulated, and finally a fire is formed. By selecting the breaker with the triple protection functions of overload, short circuit or electric leakage, the circuit can be subjected to full fault protection, and independent operation of each target area is really realized. If the selected circuit breaker does not protect the electric leakage, when the electric leakage occurs to the power utilization unit, the distribution box can trip, so that independent operation of each target area cannot be really realized, and if the circuit breaker is not protected by overload, great potential safety hazard can be brought.
The circuit breaker can also have the protection functions of over-temperature, over-current and the like, the safety of the circuit is protected more comprehensively, and the circuit breaker can also have an alarm function, and when the circuit breaks down, an alarm is sent to remind a user of finding the fault in time and troubleshooting potential safety hazards in time.
Further, the circuit breaker is also used for stopping outputting the supply current when detecting that the current fluctuation exceeds a preset fluctuation range.
In this embodiment, the circuit breaker can judge the fault bidirectionally, when detecting that the waveform peak value of the current at the outlet end of the circuit breaker exceeds the preset fluctuation range, it indicates that the states such as load short circuit may suddenly appear in the circuit at this moment, and the circuit breaker stops supplying power to all power consumption units connected with the circuit breaker at this moment, and the fault which may occur is pre-judged and protected in time, so that the power consumption safety is further ensured. The preset fluctuation range may be a specific parameter of the circuit breaker, and may be selected according to an actual situation of the power utilization unit, which is not limited herein.
Further, the preset load capacity includes a first current or a first power, the first current is 24A, and the first power is 5280W.
In this embodiment, the first power is a power corresponding to the electric load operating at the first current. When the first current is 24A, the first power is 5280W calculated according to the rated voltage of 220V, the voltage is less than 220V or exceeds 220V in an actual circuit, the load power fluctuates accordingly, and the calculation can be performed in combination with the actual power supply condition during wiring planning.
Further, the cross-sectional area of the power transmission main line is 4 square millimeters.
In this embodiment, when the preset load electric quantity is 24A, the sectional area can be selected for the transmission line that the sectional area is 4 square millimeters for the leading-out terminal of circuit breaker and the transmission of electricity main line between the block terminal, can satisfy the electric current of circuit and bear the weight of the demand, under the prerequisite of guarantee circuit safety, can save the wire rod cost again. It will be appreciated that power lines having a cross-sectional area greater than 4 square millimeters, preferably 4 square millimeters, may also be used. The choice of the power line connected between the circuit breaker and the consumer unit is not limited here.
Further, the preset load capacity includes a second current or a second power, the second current is 36A, and the second power is 7920W.
According to different practical situations, the segment area may be divided by using a preset load electric quantity as the first current or the first power, or may be divided by using a preset load electric quantity as the second current or the second power, or may be divided by using a part of the segment area as the first current or the first power, or may be divided by using a part of the preset load electric quantity as the second current or the second power.
Further, the cross-sectional area of the power transmission main line is 6 square millimeters.
In this embodiment, when the preset load electric quantity is 36A, the power transmission main line between the outlet end of the circuit breaker and the distribution box at least selects a power transmission line with a sectional area of 6 square millimeters, so as to meet the current bearing requirement of the line and ensure the circuit safety.
