Transformer Rectifier

          Transformer rectifier is the most commonly used power supply in the impressed current cathodic protection system, usually simply referred to as (TR Unit). It is a device that can automatically control current and voltage, converting alternating current voltage into the required output voltage and then into direct current voltage. It is mainly used to implement impressed current cathodic protection for metal structures or equipment such as pipelines, storage tanks, steel structures, and docks. This device contains a transformer for reducing the alternating voltage. And it also includes a rectifier group for converting alternating current (A.C.) to direct current (D.C.). Our company offers a comprehensive range of products featuring high reliability and low prices. Our products mainly include: transformer rectifiers, junction boxes, test piles, sacrificial anodes, reference electrodes, cathodic protection accessories,Marine Growth Prevention System, electrolytic chlorine production, and a series of related products.

          The transformer rectifier products manufactured by our company include thyristor controlled transformer rectifier, tapped transformer rectifier, variable transformer rectifier, solar powered transformer rectifier, and high-frequency switching transformer rectifier. Among them, the thyristor controlled transformer rectifier include intelligent rectifiers and analog rectifiers.

1.Thyristor controlled transformer rectifier

          Thyristor controlled transformer rectifier is a rectifier device that uses silicon controlled for voltage regulation and current stabilization, which is mainly used to convert alternating current into stable direct current.Thyristor rectifier has stable output current and voltage, low power consumption, long service life, easy operation and easy maintenance.

(1)Intelligent rectifier: the intelligent type rectifers is based on intelligent microcomputer development rectifers, which intelligent control board and trigger board compose of control circuit, shows diversify by the display LCD, the four key with the operating interface compose of operation part . This equipment can realize the local store data, as well as long-distance intelligent control etc. With advantages of simple structure, intelligent, simple operation interface and easy to upgrade, etc.

(2)Analog rectifier: analog rectifers is a traditional rectifers, control circuit consists of the analog circuit, display part is single display by digital gauge or analog gauge, the operation interface consists of potentiometer and select switch. It has feature of simple operation, easy to training, strong durable,etc.

2.Tapped transformer rectifier

          Tapped transformer rectifier is a kind of impressed current cathodic protection equipment with simple structure, easy operation, strong reliability and suitable for the harsh environment in the field.It is mainly composed of tapped transformer, rectifier module, multi-channel switch etc. The tap of transformer is adjusted by the multi-channel switch, and then control the output of rectifier. Generally, there are many types, for example, 16 steps, 25 steps, 32 steps and 64 steps, it can be set and option according to the required minimum step in local. The tapped transformer rectifier is a fully open bridge rectifier, which working efficiency can achieve more than 80% .

3.Variable transformer rectifier

           Variable transformer rectifier is a kind of rectifier composed of variable transformer, main power transformer, rectifier bridge and other main components. Its working principle is similar to Tapped transformer rectifier. It does not need to output current through the stepping switch. By using the Variable transformer, it overcomes the short board of the Tapped transformer rectifier's output leaping regulation and realizes the non-pole regulation of 0~100% of the output voltage.Variable transformer rectifier features adjustable voltage range, simple operation and strong durability.
