Rectifiers PBI T
Thyristor rectifiers are designed to supply appropriate DC consumers or inverters as well as to charge battery. The device is typically used as part of an emergency power supply and/or power supply system.
About product
PBI T systems have been designed to meet the rigorous requirements in nuclear power plants. Due to the design that allows the device to operate without fans, the time of trouble-free operation is significantly extended. The PBI T system enables the construction of rectifiers with high output power. This rectifier draws a sinusoidal current from the mains which is very important, especially in case of high power.
The device is equipped with a microprocessor (DSP) control system with an intuitive HMI interface.
Rectifier PBI T characteristics:
Rectifier provides:
The device has the following protection systems:
- against overheating of the power circuits,
- against short-circuit currents,
- against overvoltage.
Rectifier allows to charge battery in 3 modes:
- Buffer operation. In this mode, the device supplies power to the battery and/or loads with a voltage of a high level of stability and the required value (usually 2.23 V/cell). The buffering voltage is compensated thermally by means of a thermal probe which is present in standard equipment and which should be placed near the powered battery.
- Automatic charging. If the battery is discharged completely or partially (for example as a result of a supply voltage failure), the battery should be recharged as soon as possible in order to prepare it to operate in case of another possible failure. Increasing the voltage by some value will make it possible to equalize the charge in the cells. For this reason, the power supply has been equipped with a mode of automatic charging to the voltage of 2,4V/cell.
- Supervised charging. In case of cooperation with open acid batteries, additional equalizing charging of the battery to the voltage of 2,7V/cell should be performed periodically. In this mode, the voltage value limit is 2,7V/cell, and the charging current is set in a simple manner by means of the keyboard during the operation of the power supply.
Each device consists of:
- Power supply unit that includes: 6- or 12-pulse mains transformer that ensure galvanic isolation of the output voltage from the mains and levels the output voltage level. Two 6-pulse thyristor bridges ensuring regulation of voltage levels and output currents.
- Microprocessor DSP controller which:
– shapes the control signals of thyristor bridges,
– performs the function of the parameter supervision system,
– decides on the choice of operation (automatic battery charging or buffer operation),
– corrects the voltage value depending on the battery temperature,
– limits the battery charging current to the set value,
– generates alarm signals,
– communicates with external supervision systems. - Front panel operating console containing:
– LCD screen displaying device parameters and status,
– LED synoptic,
– digital potentiometer, which allow you to navigate through the menu items on the LCD screen, view the status of the device and measured parameters. - Panel of connections and protections, containing:
– input and output fuses,
– ingoing and outgoing cable connections,
– device status alarm relay connections. - Battery current measuring system that measures the battery circuit current using a current measuring transducer, located outside the device.
- The KDZ system, which measures earth fault values in DC installation circuits (earth fault control of battery poles).
