In the embodiment of the invention multiple output distribution device, the matching problem of level before and after all existing between each grade distribution module, the principle that in the embodiment of the invention this coupling need be followed is called matching selection principle.Owing to all be the relation of series connection between each grade distribution module; therefore at first need to comprise general series connection matching principle in the matching selection principle of the embodiment of the invention; mainly the series connection between the ampacity of the load current of the rated current of protection switch, protection switch institute tape loop and cable is mated in each grade of finger distribution module; wherein; the ampacity of cable represent the to flow through current flow of cable; and the effective action electric current instigates protection switch to implement the electric current of overload protection, and this electric current is generally a bit several times of protection switch rated current.With the two-stage distribution is the example explanation, and this series connection matching principle mainly contains following 3 points:
1) the rated current I of protection switch
n, should be not less than the load current I of institute's tape loop
b
2) the ampacity I of cable
z, should be not less than the rated current I of protection switch

3) protection switch effective action electric current I at the appointed time
2, should be not more than current-carrying capacity of cable I
z1.45 times.
Make and be formulated above-mentioned general series connection matching principle and be: I
b≤ I
n≤ I
zAnd I
2≤ 1.45 * I

Between the load current of first order Power entry module 201 in the multiple output distribution device of the present invention and the protection switch rated current in the second level Power entry module 202, protection switch institute tape loop and the ampacity of cable, all need follow above-mentioned series connection matching principle.
Except above-mentioned general series connection matching principle; in the matching selection principle of the embodiment of the invention, also need comprise: the principle of the rated current coupling of the corresponding protection switch of the first order Power entry module 201 in the multiple output distribution device and the output current of second level Power entry module 202.
The major function of protection switch is to finish the overload protection of electric current; as a kind of execution mode; can select circuit breaker or fuse as protection switch; and different circuit breakers and fuse are after producing; producer can provide time current curve data that should device; this curve has reflected the electric current of the device of flowing through and the correlation of time, and shows the zone that device is implemented the overload protection correspondence, and this zone can be called the action band.According to above-mentioned time current curve; select the protection switch of prime Power entry module corresponding every road output; the nonoverlapping action band of protection switch of corresponding every road output with secondary Power entry module; when making the protection switch of secondary Power entry module implement overload protection; the protection switch of prime Power entry module is not implemented overload protection; then according to above-mentioned selection again in conjunction with empirical value; make the rated current of protection switch in the prime Power entry module, with the concrete multiple relation of the rated current of protection switch in the secondary Power entry module.Because the device property difference of each manufacturer production, the formulation result of therefore concrete selection and multiple relation understands different, the data that should provide with reference to producer according to actual conditions.
Provide below in a kind of embodiment of the invention, in conjunction with above-mentioned selection principle and empirical value, the prime Power entry module that draws and the rated current matching result of secondary Power entry module protection switch:
1) summation of secondary Power entry module institute bringing onto load electric current, be less than or equal the prime Power entry module provide the rated current of the corresponding protection switch of the single channel output of input for it;
2) if the protection switch of prime Power entry module and secondary Power entry module corresponding every road output all is a circuit breaker, then the prime Power entry module is bigger more than 1.3 times than the rated current of each road output protection switch of secondary Power entry module for the rated current that secondary Power entry module provides the two-way of input to export corresponding protection switch; If the protection switch of prime Power entry module and secondary Power entry module corresponding every road output all is a fuse, then the prime Power entry module is bigger more than 1.6 times than the rated current of each road output protection switch of secondary Power entry module for the rated current that secondary Power entry module provides the two-way of input to export corresponding protection switch; If the protection switch of prime Power entry module corresponding every road output is a fuse; the protection switch of secondary Power entry module corresponding every road output is a circuit breaker; then the prime Power entry module is bigger more than 1.4 times than the rated current of each road output protection switch of secondary Power entry module for the rated current that secondary Power entry module provides the two-way of input to export corresponding protection switch, and the former is according to formula I
2The value that t calculates is greater than the latter, and wherein I is the electric current value through protection switch.
Mentioned above principle 1) illustrate that the power of secondary Power entry module is subjected to the restriction of prime Power entry module power, therefore secondary Power entry module with load be generally low power consumption equipment and other auxiliary devices.Mentioned above principle 2) the coupling combination foundation that each grade distribution module selection circuit breaker or fuse are different is described.
According to above principle, be example with the two-stage distribution, in the embodiment of the invention multiple output distribution device, suppose that first order Power entry module 201 and second level Power entry module 202 all use circuit breaker to be protection switch.Power entry module 202 bringing onto load electric currents in the second level are less than the rated current that circuit breakers are exported on first order Power entry module 201 each road.In addition, first order Power entry module 201 provides the rated current of circuit breaker of the two-way output of input for second level Power entry module 202, and is bigger more than 1.3 times than the rated current of the circuit breaker of each road output of second level Power entry module 202.
According to the above matching principle, can select the input of the output of first order Power entry module 201 flexibly as second level Power entry module 202.
As a kind of execution mode, all the rank Power entry module inside in the multiple output distribution device can further include lightning protection unit and/or monitoring unit, be used for the lightning protection of input current is detected, and the function that input/output state is realized monitoring.
Lightning protection unit, the input current that the Power entry module input unit provides under being used for receiving carries out lightning protection and detects, and testing result is offered monitoring unit.
Monitoring unit, the input current that the Power entry module input unit provides under being used for receiving, carrying out input state detects, and the output current that allocation units provide in the Power entry module under receiving, carry out outputs state detection, the lightning protection testing result that will provide to the testing result and the lightning protection unit of input and output, Power entry module sensor external under offering.External sensor can carry out subsequent action according to The above results, when for example undesired or input lightning protection testing result is undesired when the input and output testing result, triggers corresponding guard block Power entry module is protected.
Above-mentioned lightning protection unit and monitoring unit are not the essential parts of each grade distribution module in the multiple output distribution device, and the function of lightning protection and monitoring also can be realized separately by other outer functional modules of multiple output distribution device, repeat no more here.
In actual applications, the Power entry module in the embodiment of the invention multiple output distribution device can select different devices to realize its function.For example, in the Power entry module of multiple output distribution device, realize above-mentioned lightning protection and monitoring function if desired, can adopt the realization device of block terminal as Power entry module.If for secondary Power entry module, to the function of lightning protection and monitoring and when having not a particular requirement, also can adopt only provides to the distribution of input power supply with to the junction box of input and output overcurrent protection, as the realization device of secondary Power entry module.
