Embodiment
With the example of accompanying drawing, the utility model is further described below.
As shown in Figure 1, a kind of multichannel centrally connected power supply energy management distributor that the utility model provides, comprises access unit MAU1, capping unit DCU3 and is connected both expanding element ESU2.
Access unit MAU1 and capping unit DCU3 are provided with inverter, and access unit MAU1 inverter is DC/DC inverter, and capping unit DCU3 inverter is DC/DC or DC/AC inverter.
Expanding element ESU2 comprises expanding element 21 and energy management distributor 22, described energy distributor 22 is with communication monitoring interface, energy distributor 22 display screens are liquid crystal display screen, the modularized design of described energy management distributor function, the output of each distributor Ke4/8 road, detection is independently controlled on every road, and energy management distributor is built-in with power transformer, rectification circuit, filter circuit, voltage stabilizing circuit, the distribution of voltage constant electric current.
Energy management distributor is to carry out the equipment of allocation manager from the direct current energy of local side apparatus output.Energy management distributor can be arranged on local side side, also can be arranged on far-end and survey.Two kinds of equipment of Ke Fen tetra-tunnel output Huo Ba road outputs.It can on-the-spot set the cut-off current of every road output, can automatic step-down in the time that output current is greater than set point or judgement export this line feed, and do not affect the normal output on other each road.Energy management distributor 485 communication functions have warning dry contact output function simultaneously, and accessible network or dynamic monitoring system, reach the effect of remote monitoring.
A kind of multichannel centrally connected power supply of the utility model energy management distributor is to aim to solve digital light distribution far-end unit scattered distribution, and being subject to powers nearby affects and efficient, the safety of developing, the multichannel centrally connected power supply product that antijamming capability is strong.This utility model utilizes dedicated communications cable or optoelectronic composite cable to provide feed by relay extension unit to far-end unit equipment, solve difficult problems such as disperseing the far-end difficulty that power supply accesses nearby, make installation, the addressing of load equipment more convenient, Remote feeding is put under the uniform management simultaneously, system operation is more reliable, and maintenance workload reduces in a large number.Tool has the following advantages:
Maintainable: remote electric power system utilizes the mediums such as telecommunication cable, netting twine, feeder line to provide feed to Remote Communications Terminal equipment, cooperation that need not power department; Compare the UPS equipment of installing, there is higher reliability and fail safe, be not subject to battery capacity, the restriction in battery charging and discharging life-span, need not be long worried for the mains failure time, also need not look like UPS equipment, must regularly patrol and examine and change used and scrapped battery to every UPS, greatly reduce and safeguard and operation cost, greatly improve the operation service quality of network.
Fail safe: supplying voltage suspends over the ground, is empty voltage to the earth, only has in the time that two groups of lines of opposed polarity contact simultaneously, just has electric current and produces; There is overvoltage, overcurrent protection and lightning protection function; Local side apparatus has thorough short circuit, overcurrent protection function, can be because of overcurrent or short circuit and burn cable.
Reliability: input, output device are for functions such as lightning protection function and overvoltage, overcurrent protection and protection to error-polarity connection, and guarantee equipment is installed, reliability of operation.Because remote feeding electricity is direct voltage, can other service signal in cable not produced and be disturbed.
Adaptability: far-end unit volume is little, lightweight, good heat dissipation, antijamming capability are strong, be applicable to being arranged in hoistway and outdoor built on stilts (outdoor type) articulate, pole, wall hang.
High efficiency: local supply module and far-end modular converter adopt LLC resonant circuit topologies, has that conversion efficiency is high, volume is little, lightweight, reliability high.
Extensibility: local supply adopts modularized design, on demand flexible expansion.
Overvoltage protection: when mains input voltage exceedes 270V ± 10V and continues to reach after 3 seconds, electric leakage switch tripping protection, the overvoltage malfunction indicator lamp above panel is bright.When city power recovery is within the scope of 105V-265V and after lasting 30 seconds, overvoltage trouble shooting, overvoltage indicator light extinguishes, if system is again without automatic reclosing power supply protector automatic reclosing of other faults.
Under-voltage protection: when mains input voltage is less than 100V ± 10V and continues to reach after 3 seconds, electric leakage switch tripping protection, the under-voltage indicator light above panel is bright.When city power recovery is within the scope of 105V-265V and after lasting 30 seconds, under-voltage trouble shooting, under-voltage indicator light extinguishes, if system is again without automatic reclosing power supply protector automatic reclosing of other faults.
Earth leakage protective: when electricity leakage sensor detect arbitrary relatively when leakage current exceedes 200mA, trip protection; When leakage current returns within the scope of 150mA and continues after 30 seconds, leak current fault is removed, if system is again without automatic reclosing power supply protector automatic reclosing of other faults.
Overcurrent protection: after system output current is greater than 3 seconds of overcurrent set-point, system trip protection, overcurrent/short circuit indicator light is long bright.Automatic reclosing power supply protector can carry out reclosing trial after 30 seconds.After overcurrent is removed, automatic reclosing power supply protector can continue normal work.
Short-circuit protection: in the time that system output current is greater than 50A, system can be in 50 milliseconds trip protection, now overcurrent/short circuit indicator light flicker, protector self-locking.Only have unshorting fault (deenergization reopens power supply after waiting a moment) the automatic reclosing power supply protector after starting system of laying equal stress on again to close a floodgate.
Zero-line open-circuit protection: the input zero line that AC power detected when current transformer disconnects, and system is answered trip protection, to protect rear class equipment to damage because of neutral point potential shift.
Embodiment recited above is described preferred implementation of the present utility model; not scope of the present utility model is limited; do not departing under the prerequisite of the utility model design spirit; various distortion and improvement that the common engineers and technicians in this area make the technical solution of the utility model, all should fall in the definite protection range of claims of the present utility model.
