Abstract
The invention provides fast recovery rectification diode parallel connection modules which comprise a number of rectification diodes. The cathodes of the rectification diodes are screwed on a copper base through screws. Two anode pins of the rectification diode are parallelly welded on another copper plate. The fast recovery rectification diode parallel connection modules provided by the invention have the advantages that the modules provided by the scheme are simple in structure, are suitable for the requirements of a power supply of electrochemical corrosion industry, and at the same time have the advantages of high voltage-resistant grade and high voltage overshoot ability; the modules undergo disconnection rather than short circuit under the condition of a failure, and cascading failures are avoided; due to the fact that the number of the modules in parallel connection is large, the current design margin of the modules is large; if a module is broken, the use of the whole system is not affected; and the cost of the modules in parallel connection is lower than the cost of similar products in market.
Description
Technical field
The present invention relates to a kind of diode, especially relate to a kind of fast-recovery commutation diode parallel module.
Background technology
Now high-power fast-recovery commutation diode module is on the market that to bear voltage overshoot ability low on the one hand, on the other hand owing to being subject to the impact of packing forms, make it not be suitable for the be corrosive environment of gas of electrochemical industry, affect use and the performance of whole system.And the single tube that voltage overshoot ability is strong, can not be suitable for again the instructions for use of big-power rectification power supply.
Summary of the invention
The object of this invention is to provide a kind of simple in structure, fast-recovery commutation diode parallel module that intensity is really up to the mark, safe and reliable.
Technical scheme of the present invention is: a kind of fast-recovery commutation diode parallel module, comprise some rectifier diodes, the negative electrode of some described rectifier diodes is screwedly mounted on copper base with screw, and two anode pins of some described rectifier diodes are also welded on another piece copper coin.
Preferably, the single tube model of described rectifier diode is HFA50BT60.
Preferably, on described copper base, there are some fixing holes.
Advantage and good effect that the present invention has are:
Technique scheme modular structure is simple, is applicable to the requirement of electrochemical corrosion industry power supply, and voltage withstand class is high simultaneously, and voltage overshoot ability is strong; The module not short circuit of only can opening circuit under failure condition, can not cause cascading failure; Because parallel module quantity is many, the current design nargin of module is larger, if there is a module to blow, also can not affect the use of whole system; Such parallel module cost is lower than like product on market.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure:
1, rectifier diode 2, negative electrode 3, anode pin 4, copper base
5, copper coin 6, fixing hole
Embodiment
Below in conjunction with the drawings and the specific embodiments, the invention will be further described.
As shown in Figure 1, the present invention includes 8 rectifier diodes 1, the negative electrode 2 use screws of 8 described rectifier diodes 1 are screwedly mounted on copper base 4, the anode pin 3 of 8 described rectifier diodes 1 is also welded on another piece copper coin 5, the single tube model of described rectifier diode 1 is HFA50BT60, on described copper base 4, has some fixing holes 6.Copper base 4 and copper coin 5 are respectively negative electrode of the present invention and anode.
In use, by fixing hole 6, the present invention can be connected with loop or other electronic components.Modular structure of the present invention is simple, is applicable to the requirement of electrochemical corrosion industry power supply, and voltage withstand class is high simultaneously, and voltage overshoot ability is strong; The module not short circuit of only can opening circuit under failure condition, can not cause cascading failure; Because parallel module quantity is many, the current design nargin of module is larger, if there is a module to blow, also can not affect the use of whole system; Such parallel module cost is lower than like product on market.
Above execution mode has been described in detail the present invention, but described content is only preferred embodiment of the present invention, can not be considered to for limiting practical range of the present invention.All equalization variations of doing according to the present patent application scope and improvement etc., within all should still belonging to patent covering scope of the present invention.
