Abstract
Disclosed is a low voltage access to household drainage distribution box, arranged at the wire inlet portion of a low voltage user meter box and comprising a box body, wherein the box body is internally provided with four aluminium rows; the A, B, and C three-phase live wire and the O phase zero wire of the low voltage network power transmission line are respectively connected to the four aluminium rows; the low voltage user electric energy meter, based on the power consumption, is respectively connected with three aluminium rows connected with the A, B, and C three-phase live wire in a grouping manner via the drainage wires having the number equal to that of the low voltage user electric energy meter; and the zero wire of the low voltage user electric energy meter is connected with the aluminium row connected with the O phase zero wire. The low voltage access to household drainage distribution box changes the conventional wiring mode of the low voltage network power transmission line and the low voltage user electric energy meter, and improves the low voltage user voltage quality.
Description
Technical field
The utility model relates to electric power system distribution low-pressure side register one's residence equipment and metering device, especially relates to a kind of low pressure drainage coupling box of registering one's residence.
Background technology
" low-voltage " phenomenon is an outstanding social concern that shows in recent years, and along with electrical equipment such as air-conditioning, electromagnetic oven, refrigerator, electric cooker are popularized use in the rural area, the rural electricity consumption load increases substantially year by year; Some are local because the user side brownout; Directly have influence on the normal use of household electrical appliance, peasant household's reflection electrical equipment can not start and the normal complaint of using is increase trend, and the seriousness of " low-voltage " phenomenon strengthens year by year; Coverage enlarges year by year; Duration increases year by year, and therefore, " low-voltage " comprehensive regulation work is grabbed as the current top priority of electric power system.
At present; The mode of connection of low-voltage customer table case is a low-pressure side service wire introducing table case; Table meter inlet wire all inserts on a drainage thread, makes several user power utilization load concentration on a point, and the big more voltage of loading is low more; When supply power voltage is lower than the power consumption equipment rated voltage, electrical equipment can not normally start.
Summary of the invention
For addressing the above problem, the purpose of the utility model provides a kind of low pressure drainage coupling box of registering one's residence, and through changing the mode of connection, increases the method for conductor cross-section, improves low-pressure side user quality of voltage.
For realizing the foregoing invention purpose, the utility model adopts following technical scheme:
A kind of low pressure drainage coupling box of registering one's residence; Be arranged on low-voltage customer gauge table case point of incoming cables; It includes a casing; Be provided with four aluminium rows in the casing; The A of low-voltage network transmission line, B, C three-phase firewire, O phase zero line are connected on four aluminium row, the low-voltage customer electric energy meter according to power consumption with the mode of dividing into groups through being connected on three aluminium rows that link to each other with A, B, C three-phase firewire with the identical drainage thread of low-voltage customer electric energy meter quantity, the zero line of low-voltage customer electric energy meter be connected with O mutually the aluminium that links to each other of zero line arrange.
The described low pressure drainage coupling box of registering one's residence, its aluminium row's thickness is 10 ~ 15cm.
Owing to adopt aforesaid technical scheme, the utlity model has following superiority:
This low pressure drainage coupling box of registering one's residence; It has changed the mode of connection of original low-voltage network transmission line and low-voltage customer electric energy meter; On average sharing of load is arrived A, B, the C three-phase of low-voltage network transmission line according to the user power utilization amount; Each user draws a drainage thread separately from low pressure is registered one's residence the drainage coupling box, loop, a family; Through improving low pressure service wire, drainage thread conductor cross-section; Reduce the conductor resistance coefficient; The register one's residence aluminium row of 10 ~ 15cm thickness of adopting in the drainage coupling box of low pressure increases contact point area, reduces the equipment heating defective; Improve the effect of low-voltage customer quality of voltage, prolonged the useful life of controller switching equipment and user power utilization equipment again.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Among the figure: the 1-casing; 2-aluminium row; 3-crimping bolt; The 4-drainage thread; 5-low-voltage customer electric energy meter; 6-low-voltage customer gauge table case.
Embodiment
Below through embodiment and combine accompanying drawing that the utility model is done further explain.
As shown in Figure 1; This low pressure drainage coupling box of registering one's residence; Be arranged on low-voltage customer gauge table case 6 points of incoming cables; It includes a casing 1, is provided with four aluminium rows 2 in the casing, and aluminium row's thickness is 10 ~ 15cm; Offer several screws on the aluminium row; The A of low-voltage network transmission line, B, C three-phase firewire, O phase zero line are connected on four aluminium row 2 through crimping bolt 3 respectively, and low-voltage customer electric energy meter 5 is connected on three aluminium rows 3 that link to each other with A, B, C three-phase firewire through crimping bolt 3 respectively through the drainage thread 4 identical with low-voltage customer electric energy meter quantity with the mode of dividing into groups according to power consumption, the zero line of low-voltage customer electric energy meter be connected with O mutually the aluminium that links to each other of zero line arrange.
