Abstract
The utility model provides an intelligent box transformer for a street lamp. The intelligent box transformer is formed by a high voltage load switch (1), a single-phase transformer (2), a street lamp controller (3) and an air switch (8) with leakage protection. A high voltage side of the single-phase transformer (2) is connected with a high voltage vacuum circuit breaker (1). A low voltage side of the single-phase transformer (2) is connected with a street lamp (6) through the air switch (8) with leakage protection. The street lamp controller (3) controls the switching of the high voltage load switch according to a set value and operation condition, and at the same time, the street lamp controller (3) obtains street lamp running information through a street lamp control line (7). According to the utility model, a single-phase special controller is employed, a load switch is installed at a high voltage side of the single-phase special controller, low-voltage three-phase load unbalance and full load and overload running of a distribution transformer can be avoided, there is no transformer no-load loss, the Intelligent box transformer has a good stabilization effect for a low voltage power network, the quality of power supply can be raised, and power energy is saved. The intelligent box transformer is suitable for the power management of city street lamps.
Description
Technical field
The utility model relates to a kind of street lamp special intelligent molding box and becomes, and belongs to the illuminalive power-supply technical field.
Background technology
Along with the urban construction develop rapidly, the city lighting engineering construction is also following in recent years, and street lamp plays main effect in city lighting, and street lamp spreads over the streets and lanes and the important high speed company both sides in city.Street lamp inserts and mainly contains dual mode, and a kind of mode adopts and inserts public the change on the spot, because the street lamp load has caused the distribution transforming three-phase imbalance for single-phase load, increases the low-voltage circuit loss, has increased public varying load pressure simultaneously; Another kind of mode adopts street lamp specially to become, but can not control the switching of special change, and the no-load loss that specially becomes is bigger.To above problem, the utility model has designed street lamp special intelligent molding box and has become, and solves the big and three-phase imbalance problem of distribution transforming load pressure, reduces the urban distribution network current supply loss.
Summary of the invention
The purpose of the utility model is, can not control switching and the bigger problem of no-load loss according to the existing special change of street lamp, and the utility model provides a kind of street lamp special intelligent molding box to become.
The technical scheme of the utility model is that the utility model street lamp special intelligent molding box becomes to be made up of high-pressure vacuum breaker 1, single- phase transformer 2 and 3 of controller for road lamp; The high pressure side joint high-pressure vacuum breaker 1 of single-phase transformer 2, the low-pressure side of single-phase transformer 2 connects street lamp 6 through being with earth leakage protective air switch; Controller for road lamp 3 is according to the switching of set point and operation conditions control high-pressure vacuum breaker 1, and simultaneously, controller for road lamp 3 obtains the street lamp operation information through street lamp control line 7.
The utility model adopts single-phase dedicated transformer, reduces cost, and is easy for installation, improves the utilance of special varying capacity; On-load switch is installed in single-phase dedicated transformer high-pressure side, and the switching that controller for road lamp specially becomes according to the set point may command reduces no-load loss.
The beneficial effect of the utility model and prior art comparison is that the utility model adopts single-phase dedicated transformer, and in single-phase dedicated transformer high-pressure side on-load switch is installed, and according to the special switching that becomes of set point may command, reduces no-load loss through controller for road lamp.The utility model can avoid causing low pressure three-phase load imbalance and distribution transforming is fully loaded and the overlond running phenomenon, and low voltage electric network has been played good stabilization, can improve power supply quality, the conservation of power energy.
The utility model is applicable to the power supply management of city street lamp.

Fig. 1 is that the utility model street lamp special intelligent molding box becomes structural representation;
The 1st, high-pressure vacuum breaker; The 2nd, single-phase transformer; The 3rd, controller for road lamp; The 4th, 10kV high pressure inlet wire; The 5th, the outlet of single-phase transformer low pressure; The 6th, street lamp; The 7th, the street lamp control line; The 8th, be with earth leakage protective air switch.
Embodiment
The embodiment of the utility model is as shown in Figure 1.
Present embodiment street lamp special intelligent molding box becomes to be made up of high-pressure vacuum breaker 1, single- phase transformer 2 and 3 of controller for road lamp; The high pressure side joint high-pressure vacuum breaker 1 of single-phase transformer 2, the low-pressure end of single-phase transformer 2 connects street lamp 6 through earth leakage protective air switch 8; Controller for road lamp 3 is through 7 monitorings of street lamp control line and obtain the street lamp operation information, and controller for road lamp 3 is according to the switching of set point and operation conditions control high-pressure vacuum breaker 1 simultaneously.
Present embodiment single-phase transformer high-pressure side is 10kV, and high-pressure vacuum breaker is the 10kV high-pressure vacuum breaker, adopts overcurrent and fast tripping protection, and the point of incoming cables of switch increases one group of lightning arrester with protection switch and transformer; Low-pressure side is 220V, and low-pressure side connects street lamp through being with earth leakage protective air switch, and the earth leakage protective air switch of low-pressure side band carries out overcurrent, overload and earth leakage protective.
Can not only the stabilizing low voltage electrical network after present embodiment is implemented, improve power supply quality, can also be according to the switching of setting the single-phase dedicated transformer of control, thus reduce no-load loss, reach the purpose of saves energy.
