Description
Technical field
The utility model relates to a kind of front and back split pole type rectifier cabinets.
Background technique
Cophase counter parallel connection be it is a kind of will simultaneously turn on but opposite polarity group of bus tightly sticks together, directly use insulation material
Material isolation, the electric current passed through is all equal in magnitude, contrary in any moment, keeps respective generated alternating flux inverse two
And the mechanism that the periphery of conductor is cancelled out each other, to greatly reduce each section line reactance, and increase alternate, impedance between arm pair
Title property fundamentally solves shell hot-spot caused by the alternating flux of high current, and reactance pressure drop increases, and parallel element is equal
Drop is flowed down, the problems such as increasing is lost, improves Rectification Power Factor efficiency and power factor (PF).
But due to being snug against between positive and negative once there is insulation breakdown, it is positive and negative between will short circuit, and be big at short circuit
Specification bus can not be turned off by a large amount of electric currents, to cause crushing blow to rectifier cabinet.
Utility model content
Its purpose of the utility model, which is that, provides a kind of front and back split pole type rectifier cabinet, solve existing rectifier cabinet but due to
Be snug against between positive and negative once there is insulation breakdown, it is positive and negative between will short circuit, and short circuit place is big specification bus, can be passed through
A large amount of electric currents do not turn off, to there are problems that crushing blow can be caused to rectifier cabinet.
Adopt the technical scheme that achieve the above object, a kind of front and back split pole type rectifier cabinet, including positive single cabinet and
Cathode single cabinet, it is described anode single cabinet and cathode single cabinet in include fixed bracket, the fixed pedestal upper end be equipped with multiple groups branch
Porcelain vase is supportted, every group of support porcelain vase upper end is equipped with switching overvoltage baffle, and switching overvoltage baffle upper end is equipped with straight
Stream output is arranged, and direct current output arranges upper end and is equipped with rectification row, and the row of rectification is equipped with element, and the element is melted bridge arm and be fixed on fastly
Fast molten connection on fast molten row, the fast molten row upper end connect commutation absorption plant, commutation absorption plant connection exchange input row.
Beneficial effect
The utility model has the following advantages that compared with prior art.
1. the present apparatus solves existing rectifier cabinet but due to being snug against between positive and negative once there is insulation breakdown, it is positive and negative it
Between will short circuit, and short circuit place can not be turned off, thus in the presence of that can cause to rectifier cabinet by a large amount of electric currents for big specification bus
The problem of crushing blow；
It is positive and negative respectively in 2 independent cabinet bodies 2. the present apparatus is made of 2 single cabinets, it can prevent to generate positive and negative arcing；
3. independent two cabinet of the present apparatus uses cophase counter parallel connection structure in exchange input position, make the magnetic field phase between positive and negative
Mutually offset.
Detailed description of the invention
Below in conjunction with attached drawing, the utility model is described in further detail.
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural side view of the utility model；
Fig. 3 is the structure top view of the utility model；
Fig. 4 is the topology view in the utility model Fig. 1 at A-A；
Fig. 5 is the topology view in the utility model Fig. 1 at B-B.
Specific embodiment
With reference to the accompanying drawing, the utility model is further described.
The present apparatus includes positive single cabinet 4 and cathode single cabinet 5, as Figure 1-Figure 5, the anode single cabinet 4 and cathode single cabinet 5
It inside include fixed bracket 13, fixed 13 upper end of bracket is equipped with multiple groups and supports porcelain vase 12, every group of 12 upper end of support porcelain vase
It is equipped with switching overvoltage baffle 11,11 upper end of switching overvoltage baffle is equipped with direct current output row 10, direct current output
It arranges 10 upper ends and is equipped with rectification row 7, rectification arranges 7 and is equipped with element 1, and the element 1 is through molten bridge arm 3 fastly and is fixed on fast molten row 8
Fast molten 2 connection, 8 upper ends of the fast molten row connect commutation absorption plant 9, the connection exchange input of commutation absorption plant 9 row 6.
The element 1 of every group of 12 upper end of support porcelain vase, fast molten bridge arm 3 and fast molten 2 are 3.
The purpose of the utility model is to provide a kind of front and back split pole type rectifier cabinet, the rectifier cabinet is by positive single cabinet 4 and cathode
Single cabinet 5 forms, positive and negative respectively in 2 independent cabinet bodies, can prevent to generate positive and negative arcing, and independent two cabinet is exchanging
Input position uses cophase counter parallel connection structure, and the magnetic field between positive and negative is made to cancel out each other；It is fast molten with the same polarity element of phase in cabinet
Bridge arm is fixed on busbar row by the way of the two-sided installation to folder；Welding manner, confluence are used between element rows and busbar connector
Row bottom falls on domain one overall structure of formation by insulator, and exchange output is from top input, and direct current output is from lower part
Confluence output.
