Brief description of the drawings
Fig. 1 is the structural representation of the voltage dropping silicon chain of integrated current divider collection control mother current of the present utility model；
In the accompanying drawings, the list of designations represented by each label is as follows：
1 silicon chain mounting base
2 aluminium alloy heat radiators
3 seven decompression diodes
4 current dividers
Embodiment
Principle of the present utility model and feature are described below in conjunction with accompanying drawing, example is served only for explaining this practicality
It is new, it is not intended to limit the scope of the utility model.
It refer to shown in Fig. 1, it controls the structure of the voltage dropping silicon chain of mother current for integrated current divider collection of the present utility model
Schematic diagram；The voltage dropping silicon chain of the integrated current divider collection control mother current includes：Silicon chain mounting base 1, aluminium alloy heat radiator 2,
Diode 3 and current divider 4 are used in seven decompressions, wherein,
The aluminium alloy heat radiator 2 and the current divider 4 are all installed on the silicon chain mounting base 1, and seven decompressions are used
Diode 3 is installed on the aluminium alloy heat radiator 2；
Seven decompressions are shown as G1~G7 with diode 3 in Fig. 1, and diode G1~G7 pressure drop is all 5V, according to input
The difference of number of diodes, seven grades of pressure regulation can be achieved, range of regulation is between 5V~35V；Specifically, seven voltages are the two of 5V
Pole pipe is together in series, and the positive terminal connection closing bus bar+HM of tandem compound, negative pole end is connected to the current divider 4, the shunting
Device 4 is connected to control bus+KM；Using three relays, the first relay and first 5V diodes in parallel, the second relay
With second, third 5V diodes in parallel connected, the 3rd relay and the 4th~seven 5V diodes in parallel connected.Root
Quantity according to diode input is different, and the adjustable range of voltage is between 5V~35V.When second, third actuating of relay, first
When relay is failure to actuate, a diode is devoted oneself to work, and silicon chain can be depressured 5V；When the first, the 3rd actuating of relay, the second relay
When device is failure to actuate, two diodes are devoted oneself to work, and silicon chain can be depressured 10V；When the 3rd actuating of relay, first, second relay
When being failure to actuate, three diodes are devoted oneself to work, and silicon chain can be depressured 15V ... by that analogy, and maximum reducing value is 35V, shares seven
Level pressure regulation.
Diode can operationally produce heat, for ensure diode can normal reliable work, be installed on aluminium conjunction
On golden radiator, increase area of dissipation.The silicon chain mounting base 1 of common specification is suitably lengthened, such as can be 600~650mm,
Current divider 4 is installed on silicon chain mounting base 1；1., 2. connected by the secondary terminals interface of current divider with DC measurement instrument
Connect, it is possible to the electric current of acquisition control bus.
Preferred embodiment of the present utility model is the foregoing is only, it is all in this practicality not to limit the utility model
Within new spirit and principle, any modification, equivalent substitution and improvements made etc., guarantor of the present utility model should be included in
Within the scope of shield.
