Abstract
The utility model discloses a power supply circuit for street lamps in an alumina factory and comprises a U, V and W three-phase power supply. The U, V and W three-phase power supply is connected with a U,V and W three-phase power supply circuit through a three-pole circuit breaker QM; the U phase of the three-phase power supply circuit is connected with a group of lighting lamps D11-D1n belonging to the U phase power supply circuit through a double-pole circuit breaker QM1; the V phase of the three-phase power supply circuit is connected with a group of lighting lamps D21-D2n belonging to the V phase power supply circuit through a double-pole circuit breaker QM2; and the W phase of the three-phase power supply circuit is connected with a group of lighting lamps D31-D3n belonging to the W phase power supply circuit through a double-pole circuit breaker QM3; By adopting the power supply circuit, the lighting brightness of the street lamps can be controlled according to the requirements to keep high-consistent brightness of a whole road; and since the rate of all the street lamps going wrong is very low, the situation that all the lamps on the road simultaneously put out is avoided, and the reliability of the road lighting is effectively ensured.
Description
Technical field
The utility model relates to a kind of power supply circuits, particularly relates to a kind of alumina producer plant area street lamp power supply, road lamp power supply circuit, belongs to the street lamp power supply, road lamp power supply technical field.
Background technology
At large-scale alumina producer, factory road is very many, and is also very many for the street lamp of factory road illumination.Design in the past is that the lighting of certain section road all draws from same lighting loop, and this scheme can be saved a lot of cables.But also there is a drawback in this scheme: if certain light fixture is short-circuited on the very long road of this section, perhaps line failure then is connected on all cisco unity malfunctions of this fault point street lighting afterwards.
Summary of the invention
The purpose of this utility model is, a kind of alumina producer plant area street lamp power supply, road lamp power supply circuit is provided.Can control the brightness of street lighting as required, the brightness that whole road can both be consistent.The probability that street lamp all breaks down is very little.The situation that whole road lighting is extinguished simultaneously can not appear.Can effectively guarantee the reliability of road lighting.
The technical solution of the utility model: a kind of alumina producer plant area street lamp power supply, road lamp power supply circuit comprises U, V and W three phase supply power supply; U, V are connected with W three phase supply loop with U, V through three-pole breaker QM with W three phase supply power supply; The U in three phase supply loop through double-pole cut-out QM1 with belong to U mutually one group of illuminating lamp D11 of current supply circuit～D1n connect; The V in three phase supply loop through double-pole cut-out QM2 with belong to V mutually one group of illuminating lamp D21 of current supply circuit～D2n connect; The W in three phase supply loop through double-pole cut-out QM3 with belong to W mutually one group of illuminating lamp D31 of current supply circuit～D3n connect.
In the aforementioned alumina producer plant area street lamp power supply, road lamp power supply circuit, the U in described three phase supply loop is connected with back-up circuit through double-pole cut-out QM4.
In the aforementioned alumina producer plant area street lamp power supply, road lamp power supply circuit, described protective earth PE and the zero-power line N of comprising.
Compared with prior art, the utility model can be controlled the brightness of street lighting as required, U, V, W three-phase loop all can be opened when the needs higher brightness, and the street lamp that at this moment is connected under U, V, the W three-phase is all lighted.When only needing faint illumination, can only open an any phase or the two-phase in U, V, the W three-phase.Because of the street lamp that is connected under U, V, the W three-phase is equidistant evenly interlaced arrangement, the brightness that whole road can both be consistent.If short circuit or fault appear in U, V, the W three-phase any mutually, the probability that all the other two-phases break down simultaneously is very little.Because U, V, W three-phase are separate, and be connected to street lamp under U, V, the W three-phase, the situation that whole road lighting is extinguished simultaneously can not occur for equidistant evenly interlaced arrangement.Effectively guaranteed the reliability of road lighting.

Fig. 2 is the layout schematic diagram of street lamp in the utility model.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples, but not as to any restriction of the present utility model.
Embodiment.
The utility model as depicted in figs. 1 and 2.A kind of alumina producer plant area street lamp power supply, road lamp power supply circuit comprises U, V and W three phase supply power supply; U, V are connected with W three phase supply loop with U, V through three-pole breaker QM with W three phase supply power supply; The U in three phase supply loop through double-pole cut-out QM1 with belong to U mutually one group of illuminating lamp D11 of current supply circuit～D1n connect; The V in three phase supply loop through double-pole cut-out QM2 with belong to V mutually one group of illuminating lamp D21 of current supply circuit～D2n connect; The W in three phase supply loop through double-pole cut-out QM3 with belong to W mutually one group of illuminating lamp D31 of current supply circuit～D3n connect.The U in described three phase supply loop is connected with back-up circuit through double-pole cut-out QM4.Described protective earth PE and the zero-power line N of comprising.
Operation principle of the present utility model
As depicted in figs. 1 and 2, three-pole breaker QM and double-pole cut-out QM1～QM4 are installed among the light distribution box BL among Fig. 1, double-pole cut-out QM1～QM3 is connected with W street lamp group D31～D3n with U street lamp group D11～D1n, V street lamp group D21～D2n respectively.The pairing loop of double-pole cut-out QM4 is standby.Being connected to U street lamp group D11～D1n that U goes up is mutually controlled by double-pole cut-out QM1 and cut-offs, being connected to V street lamp group D21～D2n that V goes up is mutually controlled by double-pole cut-out QM2 and cut-offs, be connected to W street lamp group D31～D3n that W goes up mutually and control by double-pole cut-out QM3 and cut-off, by that analogy.Street lamp is arranged the rule layout that replaces mutually by U, V, W three-phase on road.
Road lamp management person can control the brightness of street lighting as required, U, V, W three-phase loop all can be opened when the needs higher brightness, and the street lamp that at this moment is connected under U, V, the W three-phase is all lighted.When only needing faint illumination, can only open an any phase or the two-phase in U, V, the W three-phase.Because of the street lamp that is connected under U, V, the W three-phase is equidistant evenly interlaced arrangement, the brightness that whole road can both be consistent.
If short circuit or fault appear in U, V, the W three-phase any mutually, the probability that all the other two-phases break down simultaneously is very little.Because U, V, W three-phase are separate, and be connected to street lamp under U, V, the W three-phase, the situation that whole road lighting is extinguished simultaneously can not occur for equidistant evenly interlaced arrangement.Effectively guaranteed the reliability of road lighting.
