Technical field
The utility model relates to power-supply system, particularly a kind of direct current cabinet interpolation frame system.
Background technology
Dc operation power supply system is one of indispensable secondary devices such as power plant, hydroelectric station, transformer station, switching station, and its reliability directly has influence on the safe and reliable operation of power plant, substation equipment.DC power supply provides power supply for controlling load and living load and direct current emergency lighting load etc., is the basis of present electric power system control and protection.Direct current cabinet is mainly used in the middle-size and small-size power plant of electric power system, hydroelectric station, transformer station; Use the place (like petrochemical industry, mine, railway etc.) of DC equipment with other, for the instrument in circuit breaker branch, combined floodgate and the secondary circuit, instrument, relaying protection and fault illumination provide DC power supply.
The complete enterprise of present many direct current cabinets purchases the direct current cabinet core component mostly and assembles, and does not have unified standard, causes the direct current cabinet power system structure unreasonable easily, reliability, the relatively poor problem of anti-interference, and be inconvenient to safeguard and revise.
The utility model content
The problem that the utility model solves provides a kind of direct current cabinet power-supply system, solves that existing direct current cabinet power system structure is unreasonable, reliability and anti-interference is relatively poor, safeguard and revise inconvenient problem.
For addressing the above problem, the technical scheme that the utility model adopts is:
A kind of direct current cabinet interpolation frame system comprises switch element, distribution keyset, power module, voltage regulator, AC sampling plate, monitoring module, and wherein, the input of said distribution keyset connects switch element, and output connects power module; Said voltage regulator input connects said power module, and output connects the distribution keyset; Said AC sampling plate connects said switch element; Said monitoring module connects said AC sampling plate and said distribution keyset.
Further, also comprise Surge Protector, said Surge Protector is connected in said switch element.
Further, also comprise framework, said switch element, distribution keyset, power module, voltage regulator, AC sampling plate and monitoring module all are fixed in the said framework.
Further, also comprise and be arranged at the port unit that has standard interface in the said framework.
Compared with prior art, the advantage of the utility model technical scheme is:
Comprise that through the core component that direct current cabinet is required switch element, distribution keyset, power module, voltage regulator, AC sampling plate and monitoring module are incorporated in the framework; And adopt voltage regulator to replace traditional silicon chain step-down; Both saved the space; Make things convenient for operation and maintenance again, improved reliability.
Description of drawings
Fig. 1 is the utility model specific embodiment sketch map.
Embodiment
Elaborate below in conjunction with the embodiment of accompanying drawing to the utility model.
Fig. 1 is the utility model specific embodiment sketch map.As shown in Figure 1; A kind of direct current cabinet interpolation frame system comprises switch element 1, distribution keyset 2, power module 3, voltage regulator 4, AC sampling plate 5, monitoring module 6, wherein; The input of said distribution keyset 2 connects switch element 1, and output connects power module 3; Said voltage regulator 4 inputs connect said power module 3, and output connects distribution keyset 2; Said AC sampling plate 5 connects said switch element 1, and said monitoring module 6 connects said AC sampling plate 5 and said distribution keyset 2.
Said switch element 1 is opened or circuit breaker for sky; Said switch element 1 can connect the Surge Protector (not shown), plays lightning protection function.
Said distribution keyset 2 is a binding post.
Said power module 3 has rectification and filter function.
Said AC sampling plate 5 is used for the AC power of input switch unit 1 is carried out voltage signal acquisition, and the voltage signal of gathering is transferred to monitoring module 6.
Said voltage regulator 4 has substituted traditional silicon chain step-down, realizes the power supply of power module 3 outputs is carried out voltage-regulation.
Said switch element 1, distribution keyset 2, power module 3, voltage regulator 4, AC sampling plate 5, monitoring module 6 all are installed in the framework (not shown), form a box unit, make things convenient for operation and maintenance.
The port unit that has standard interface has been installed in the said framework, has been made things convenient for external equipment to be connected with it.
During said direct current cabinet interpolation frame system works, AC power inserts from switch element 1, gets into power modules 3 through distribution keyset 2 then; The AC power of 3 pairs of inputs of power module is carried out rectification and filtering, exports voltage regulator 4 then to; The power supply of 4 pairs of inputs of voltage regulator boosts or reduction regulation, and outputs to after the voltage stabilizing on the distribution keyset 2, in order to connect the feeder head of outside feeder cabinet; Simultaneously, 5 pairs of AC powers that are input on the switch element 1 of AC sampling plate adopt, and send the voltage signal that collects to monitoring module 6; Meanwhile, monitoring module 6 is also gathered power supply signals such as relevant AC power, DC power supply from distribution keyset 2, realizes the monitoring to whole system.External equipment like batteries, then is connected 5 corresponding wiring place of distribution keyset.The closing bus bar that external equipment needs only need be connected 5 corresponding wiring place of distribution keyset with the control bus and get final product.
The described direct current cabinet interpolation frame of the utility model specific embodiment system; Through the core cell that direct current cabinet is required and module integrated in framework, and adopt voltage regulator to replace traditional silicon chain step-down, both saved the space; Make things convenient for operation and maintenance again, improved reliability.
Though the utility model with preferred embodiment openly as above; But it is not to be used for limiting the utility model; Any those skilled in the art are in spirit that does not break away from the utility model and scope; Can make possible change and modification, so the protection range of the utility model should be as the criterion with the scope that the utility model claim is defined.
