36V 1000A AC to DC High frequency switching Stainless steel electrolytic polishing rectifier
The principle of stainless steel electrolytic polishing:
The main accepted theory of stainless steel electrolytic polishing is the mucosal theory. That is, after the metal ions are separated from the workpiece, a phosphoric acid film is formed on the surface of the workpiece with phosphoric acid. This kind of mucous membrane is thinner at the protrusions and thicker at the depressions because of the high current density at the protrusion Dissolution, with the fluidity of the mucous membrane, changes irregularly, the rough surface gradually becomes a smooth process
Advantages of stainless steel electropolishing:
Inside has the same color inside and outside, strong light retention, mechanical polishing can not make the notch flat.
Production has high efficiency and low cost.
(3) increase surface corrosion resistance, applicable to all stainless steel.
Requirements for electroplating and polishing of stainless steel:
The power waveform is not strict, SCR type or high frequency electroplating rectifier can be selected.
Electropolishing bath and supporting equipment (anode rod):
Rigid PVC plates are welded together. The three electrode bars on the top of the bath are in the middle of the movable anode bar, and then are connected with the anode (or positive pole), both sides are used as cathode poles, and are connected with the power cathode (negative pole).
stainless steel electropolishing process:
Stainless steel electrolytic polishing process: degreasing – washing – anti rust – washing – electrolytic polishing – washing – passivation – packaging.

2. Control mode: Local control or Remote control(the length of cable is determined by customers)
3. Japan IGBT(the default choice) or Germany IGBT are adopted
4. After being phosphated, galvanized and plastic sprayed, the chassis has excellent corrosion resistence function
5. Easy to operate and repaire
a: Adopting completely digitalized machining
b: Adopting cold rolled production of iron steel sheet, after phosphorization, zinc plating, plastic spray, the rectifier gets better structural strength and anti-corrosion.
c: Reasonable structure design, isolated inverter design, rectification part is convenient to disassemble and mend because of its neat assembling.
d: Radiator gets better cooling effect because of its 1.5 times capacity.
2 Electric control system
a: The rectifier adopts full bridge phase-shifted soft switch control, ensuring the lowest power loss of IGBT. The capacity of IGBT become 3 times bigger.
b: The main transformer. It adopts amorphous core to increase transformer efficiency and cool transformer, and not only can lighten rectifier weight, but also can strengthen rectifier stability and reliability. At its elementary stage, it adopts series blocking capacitor.
c: Magnetic deviation automatic correction circuit is adopted and the total power of magnetic core gets enlarged 1.5 times.
3 Schottky Barrier Diode
a: It has been expanded 4 times.
4 All the controlling boards get antiseptic treatment with imported lacquer.
How to install rectifier
This is installation way for remote control rectifier. Not only this way.
1. To connect copper bar with bath/tank
2. To ensure power supply/rectifier is grounded
3. To ensure there is enough water for water cooling type power supply/rectifier
4. We advice that all rectifiers should be isolated to increase of its life.
