Electrophoretic thyristor rectifier

Electrophoretic painting is a coating method that uses an external electric field to make the paint particles suspended in the electrophoretic paint liquid migrate directionally and deposit on the surface of metal workpieces. The basic principle is to take advantage of the physical property that "opposite charges attract" of charged particles, making the charged paint particles attract the electrode with the opposite charge. The electrophoretic paint liquid tank serves as one electrode, and the metal workpiece to be coated, which is immersed in the paint liquid, acts as the corresponding other electrode. When a direct current power supply is applied, the anode (cation) paint ions move towards the anode (cation) workpiece and then deposit on it, forming a uniform and continuous coating film on the surface of the workpiece. When the coating film reaches a certain thickness, an insulating layer forms on the surface of the workpiece, and the "opposite poles attract each other" force is insufficient, causing it to stop The electrophoretic painting is completed. This electrophoresis rectifier serves as the DC power supply for providing the electrophoresis electric field.

The charge on the capacitor is discharged through the 20K current-limiting resistor. Observe that the voltage on the voltmeter returns to zero. Then release the discharge button and the discharge is complete.

The AC power supply is introduced into the three-winding rectifier transformer through the main power supply air switch, AC filter, phase sequence protection relay and AC contactor. There are two three-phase windings on the secondary side of the transformer, which are connected in delta and star configurations respectively. Among the two three-phase windings, the phase difference between the in-phase windings is 30°, and the output line voltage of both is AC242V. The output of the six-phase transformer is connected to two sets of three-phase bridge thyristor rectifier modules. After rectification, it is output in series as DC650V, a 12-pulse DC voltage with an inherent pulsation coefficient of 1.4%. Then, it is filtered by the DC filter LC and connected to the DC output terminal block in two channels through the DC contactors BZ01 and BZC2. The two DC contactors can independently control any one of the outputs. Or output two channels simultaneously.

Intelligent charging equipment for torpedo batteries

The ZC-1 type torpedo battery intelligent charging equipment is the latest high-tech product developed in response to the charging and discharging requirements and characteristics of torpedo batteries. It consists of three major parts: charging, discharging and battery detection. The charging mode and charging battery can be selected through the display interface. In the charging mode, you can choose either a fixed charging mode or a set charging mode. In each mode, there are three types of rechargeable batteries available for selection, namely silver-zinc batteries, lead-acid batteries and imported batteries. In the fixed charging mode, once the charging parameters for each type of battery are set, subsequent charges will be made according to the set parameters without the need for further Settings. In the configurable mode, the operator is prompted to set parameters before charging each type of battery.

Hot-dip galvanized rectifier

Arc zinc spraying is a metal surface anti-corrosion spraying technology. It uses double-line arc spraying. The arc generated by short-circuiting a direct current power supply melts the zinc wire, and then the high-pressure gas produced by an air compressor sprays the melted zinc ions onto the metal surface, forming a zinc ion protective film on the protected workpiece. The working principle is described as follows: Two wire materials used for spraying are continuously introduced into the nozzle of the spray gun by the wire feeding mechanism. The two ends of the spray gun are connected to the positive and negative poles of the zinc spraying rectifier. The tips of the wire materials are joined at a certain Angle at the outlet of the spray gun. When the wire feeding machine is connected, the two ends of the wire materials short-circuit at the outlet of the spray gun to generate an electric arc. The high temperature of the electric arc melts the wire materials. If the arc burns stably, the wire feeder continuously pushes the wire forward. The front end of the spray gun is equipped with a nozzle that outputs high-pressure air. Under the action of the air compressor, the compressed air continuously sprays out high-pressure gas. The molten metal particles are atomized under the action of the high-pressure gas flow and are quickly sprayed onto the surface of the substrate and solidified to form a coating. The process of arc spraying can roughly be divided into three parts: the melting and atomization stage of the wire material; The flight stage of molten metal particles; The particles are sprayed onto the substrate and enter the stage of accumulation and solidification. Controlling the movement speed of the wire feeding mechanism can alter the DC output current, thereby changing the size of the molten metal particles sprayed onto the workpiece.

The entire control circuit is installed on a 268mmx225mm printed circuit board, and the number of connections with the main circuit is reduced to only twenty-seven. The main components are all imported parts and are assembled after strict aging and screening, so the reliability is very high.<br /> 2. The control board eliminates the large-sized synchronous transformer and various other control transformers in the rectifier circuit. It does not recognize the phase sequence, further simplifying the overall circuit and reducing the equipment volume. It also has a complete set of multiple protection measures such as overcurrent, overvoltage, phase loss and low water pressure. The protection action is rapid. Once a circuit fault occurs, the system can act in a very short time to reliably protect the thyristor and capacitor from damage.<br /> 3.

It has excellent current and voltage cut-off effects and features no impact during start-up and constant power regulation.
