Embodiment
As shown in Figure 1, the utility model power module mainly by ac/dc power converting circuit 1, buffer circuit 2, main power source/stand-by power supply detect circuit 3, automatic switchover decision circuitry 4 are set, circuit 5 is set cold standby/heat fully and condition indication circuit 6 six parts constitute.
The power input of ac/dc power converting circuit 1 and cold standby/heat are provided with circuit 5 fully connect after, link to each other with AC power; The output of ac/dc power converting circuit 1 links to each other with the power output terminal of power module by buffer circuit 2; Main power source/circuit 3 is set in stand-by power supply detection and automatic switchover decision circuitry 4 is connected in parallel on ac/dc power converting circuit 1 power supply outlet side.
Ac/dc power converting circuit 1 mainly is that alternating current is transformed into direct current, and direct current is carried out voltage stabilizing output.
The effect of buffer circuit 2 is: when selecting the situation of active and standby two groups of power supplys power supply for use, when main power source is worked, buffer circuit in the stand-by power supply can prevent the influence of main power source to the stand-by power supply operating state, correspondingly, when stand-by power supply was worked, the buffer circuit in the main power source also can prevent the influence of stand-by power supply to the main power source operating state.
When selecting the power supply of two groups of power supplys for use, can detect by main power source/stand-by power supply and circuit 3 is set one group of power supply is set arbitrarily is main power source, another group power supply is a stand-by power supply.
Automatic switchover decision circuitry 4 detects, judges the working condition of active/standby power supply automatically according to the setting of main power source/stand-by power supply, and when the main power source operation irregularity, the automatic switchover supply power mode is powered by stand-by power supply; In like manner, when the stand-by power supply operation irregularity, the automatic switchover supply power mode is powered by main power source.
When power module is operated in the stand-by power supply state, can circuit 5 standby power supply modules be set fully by cold standby/heat and be set to cold standby (not powering up) state or hot (powering up) state that is equipped with.The difference that cold standby/heat is equipped with is: during the cold standby state, power module needs a period of time from starting to power supply, and the response time is long; And heat is equipped with state, and power module need not the response time from starting to power supply, and speed is fast.
Condition indication circuit 6 can represent intuitively that this power module is to be operated in the powered operation state, or the stand-by power supply state; And be the cold standby state, still heat is equipped with state.
As shown in Figure 2, ac/dc power converting circuit 1 mainly comprises rectifying device group U1.Buffer circuit 2 mainly comprises diode D5.Main power source/stand-by power supply detection is provided with circuit 3 and mainly comprises commutator SW
2Automatic switchover decision circuitry 4 mainly comprises relay J, diode D1, resistance R 8, capacitor C.Cold standby/heat is provided with circuit 5 fully and mainly comprises switch SW 1.Condition indication circuit 6 mainly comprises light-emitting diode D2～D4, triode T1, T2 etc.
The power input of rectifying device group U1 in the ac/dc power converting circuit 1 links to each other with AC power by socket CH, the DC power supply of the normally-closed contact i of the positive source of U1 output by diode D5, relay J and f and power module output+extremely link to each other, the power cathode of U1 output directly with the DC power supply of power module output-extremely link to each other.The dc power anode of U1 output links to each other with the end of commutator SW2 again, the common port of SW2 links to each other with the test lead D of card insert type power module, the other end of SW2 links to each other with the relay J coil by resistance R 8, and normally opened contact g, the f of J links to each other with the input of condition indication circuit 6.Be serially connected in the U1 power input after normally-closed contact e, the c of relay J and switch SW 1 are in parallel.
During use, can simultaneously two block power supply modules 7,8 be inserted in cabinet or the control cubicle.With power module 7 outputs+utmost point and power module 8 outputs+extremely link to each other; With power module 7 outputs-utmost point and power module 8 outputs-extremely link to each other; The test lead D of power module 7 is linked to each other with the test lead D of power module 8.By main power source/stand-by power supply detection circuit 3 being set is commutator SW
2Power module 7 is arranged to main power source module, and power module 8 is arranged to standby power supply module.Rectifying device group U1 in power module 7 is intact, in the time of can normal power supply, because the not adhesive of relay J in the main power source module 7, the contact i of J links to each other with f, so the power output end+utmost point of main power source module 7 and-utmost point output DC source, power for system by main power source module 7.Because power module 7 is set at main power source module, SW
2Make that the test lead D of main power source module 7 is also simultaneously charged, the test lead D of the standby power supply module 8 that links to each other with main power source module 7 test lead D is also charged, the automatic switchover decision circuitry 4 of standby power supply module 8 is the relay J adhesive, normally-closed contact i and f disconnect, normally opened contact g, f are communicated with, power output end+the utmost point of standby power supply module 8 and-utmost point do not have DC power supply output, do not power.When main power source module 7 can not be for system's normal power supply, the power output end+utmost point of power module 7 and-utmost point do not have DC power supply output, promptly voltage is zero.At this moment, because the test lead D of main power source module 7 is not charged, the test lead D of the standby power supply module 8 that links to each other with main power source module test lead D is not charged yet, the automatic switchover decision circuitry 4 of standby power supply module 8 detects this situation, the relay J coil disconnects, normally-closed contact i and f are communicated with, the power output end+utmost point of standby power supply module 8 and-utmost point output DC source, be system's power supply.Thereby, realize the utility model when one of them power circuit breaks down, can in time be the goal of the invention of system's power supply by another stand-by power supply.
The utility model can be designed to the card insert type structure, is installed in cabinet or the control cubicle.When power module breaks down, in the time of can't operate as normal, repair and replacement in time, very simple, convenient.And, can be under electriferous state, hot plug.
When only being system's power supply with a block power supply module, be set to the stand-by power supply state if miss power module, automatic switchover decision circuitry 4 can be thought mains power failure and automatic power.
Rectifying device group U1 in the utility model ac/dc power converting circuit 1 can be rectification, the translation circuit that is made of switching circuit, also can be rectification, the translation circuit that is made of analog circuit.Because, be all to be the circuit of moulding by Switching Power Supply or by power rectifier/translation circuit that analog power constitutes, so, be not described in detail in this concrete annexation of its inside.
The above only is preferred embodiment of the present utility model, and any equivalent transformation based on technical solutions of the utility model all belongs within the utility model protection range.
