Abstract
A power supply distribution device box comprises a box body and a power supply module, wherein a device guide rail for a security-monitoring device is arranged in the box body, the power supply module comprises at least two groups of power supply inputs, wherein each group of power supply inputs are respectively equipped with a safety device, and a plurality of branch outputs are connected behind the safety device. The power supply distribution device box is a distribution system for supplying alternating current and direct current power supplies for a communication cabinet, and integrates a plurality of functions into one body.
Description
Technical field
This product belongs to a kind of communication power supply product, specifically is a kind of electric power distribution device case.
Background technology
Along with the develop rapidly of telecommunication technology, telecommunications network architecture is complicated day by day, and as the power part of communication system, the importance of the power supply system for communications embodies day by day.No matter the traditional communication power supply from supply power mode or from the technical performance index aspect of power-supply device, does not all satisfy the specification requirement of the telecommunications network that makes rapid progress far away.The technical grade of communication power supply equipment and above-mentioned various types of communication equipment is not only inharmonious, and the technical merit gap also enlarges continuing, and this is very disadvantageous to the coordinated development of communication network from now on.From improving aspects such as functional reliability, dilatation ability, should adopt the decentralized power-supply standard progressively to replace concentration supply power.For satisfying the specification requirement of communication network, also use in the decentralized power-supply in order to be adapted at, should widely popularize a collection of new power equipment such as high-frequency switching rectifier, to replace traditional controllable silicon phase-controlled power.
Summary of the invention
In order to solve above problems, the utility model proposes a kind of novel power supply distributing equipment case, concrete technical scheme is as follows:
A kind of electric power distribution device case comprises casing, power module; In casing, be provided with the equipment guide rail that is used for security protection equipment; Described power module comprises the input of at least two group power supplys, and safeties are equipped with in every group of input respectively, connects a plurality of branch road outputs behind safeties.
Described safeties comprise air switch or fuse.
Described power supply input comprises exchanging to be imported and the direct current input.
Also comprise temperature control device, this temperature control device comprises the fan and the heating module of temperature sensitive switch and temperature sensitive switch control.
Described power module connects lightning-protection module; Lightning-protection module front end series connection fuse or air switch.
Also comprise illuminator, illuminator connects the input of power module by switch.
Also comprise alarm device, supervising device, alarm device, supervising device connect described air switch.
This electric power distribution device case is the distribution system that interchange, DC power supply are provided for communication cabinet, integrates functions such as interchange, DC power supply, temperature control, lightning protection, sky are opened, air draft, heating, illumination, alarm, monitoring.

Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
A kind of electric power distribution device case comprises casing, power module; In casing, be provided with the equipment guide rail that is used for security protection equipment; Described power module comprises the input of at least two group power supplys, and air switch is equipped with in every group of input respectively, connects a plurality of branch road outputs behind air switch.Described power supply input comprises exchanging to be imported and the direct current input.Also comprise temperature control device, this temperature control device comprises fan and heating module.Described power module connects lightning-protection module.Also comprise illuminator, illuminator connects the input of power module by switch.Also comprise alarm device, supervising device, alarm device, supervising device connect described air switch.
Uninterrupted for guaranteeing communication, AC and DC all has two groups of power supply inputs in this example, and automatic air-break switch is equipped with in every group of input respectively.Behind automatic air-break switch, connect two-way output respectively.
Described temperature control device comprises fan and heating module, can start fan when temperature is high, but temperature is crossed and can be started heating module when low.This heating module is the fan type heater, and the PTC heater element is adopted in its inside, and its heater element has from the heating of temperature control constant temperature, the flames of anger, thermal conversion rate height, is subjected to supply voltage to influence advantages such as minimum, that natural life-span is long.
The fan type heater changes the heating power change self with external environment condition, lower when ambient temperature, heat absorption is more, under the situation of heater good heat dissipation, itself power is just big.Otherwise it is just little.A minitype axial flow fan has been set up in the outside, makes air generation convection current conduction in the cabinet, whole quick heating, and uniform heat distribution, dehumidifying is rapid, and effect is obvious, and components and parts in the cabinet are not had negative effect.Make heater remain at work under the low-temperature condition, prolong himself life-span greatly.
Add in interchange, the DC power supplier and join lightning-protection module, can reach C level protection (40KVA), can be equipped with the protection of B level in case of necessity.Because this lightning-protection module is more common in the prior art, at this it is not further limited.
Illuminator is the 220V illuminating lamp.
Alarm device is stand by lamp and buzzer.All all send visible alarm signal when any (or several while) air switch tripping operation is interrupted, visible alarm signal is that red stand by lamp is bright.Supervising device connects control bus, so in alarm, can also send to the alarm control signal to the total alarm of machine room.This alarm device and supervising device are more common in prior art, at this it are not further limited.
Points for attention:
Power supply connects lead with being not less than 6mm
2The multiply copper cash, earth connection is with being not less than 10mm
2The multiply copper cash, the weak point that connecting line should be tried one's best, straight, thick.
Fuse that it is suitable that the lightning-protection module front end should be connected or air switch.
