Thyristors T153 – 630A, 800A, 1000A, 1600A, 2000A, 2500A

Thyristors SCR disc type T153 AS ENERGITM are press pack type general-purpose thyristors, regulating and converting DC and AC currents to 2500A at frequencies to 500 Hz in circuits with voltages 200V to 2800V.

The T153 series thyristors have the following types (current): 630 A, 800 A, 1000 A, 1600 A, 2000 A, 2500 Ampere.

Thyristor voltage depending on series and is: 200V, 400V, 600V, 800V, 1000V, 1200V, 1400V, 1600V, 1800V, 2000V, 2200V, 2400, 2600V, 2800V.

The polarity of the thyristor is determined by the icon on the case.

Thyristor case type: T153-630, T153-800, T153-1000 - PT53: contact surface - Ø51 mm, overall dimensions - Ø75x26 mm, weight - 550 g.

Thyristor case type: T153-1600, T153-2000, T153-2500 - PT51: contact surface - Ø51 mm, overall dimensions - Ø75x14 mm, weight - 330 g.

The thyristors are assembled with the coolers by means of a threaded connection. To keep electrical losses to a minimum and heat dissipation to a maximum, the necessary torque must be provided during assembly, the so-called pressing force Fm – 24±2kN. Correspondence of the achieved clamping force to the required one is determined by the deflection of the traverse. For better heat dissipation of thyristor during assembly, heat conducting paste is used, which is not a prerequisite for installation.

The technical specifications, part numbering guide, polarity, dimensions and recommended coolers for thyristors are listed below.

Our company provides a quality guarantee for thyristors of 2 years from the date of purchase. Also provided documents confirming quality, certificates.

Installation recommendations for power thyristors:

Assembling disc thyristor with a heatsink

The reliability of heat transfer and electrical contact between the mating surfaces of the thyristor and the cooler over the entire temperature range is ensured by appropriate torque (clamping force).

Before assembly you should perform visual inspection (1) contact surfaces for mechanical damages and wipe (2), soaked with alcohol (toluene, gasoline, acetone).

After inspection, fix the current leads (petals), install a pin to fix the alignment of the structure.

To improve the parameters of heat transfer it is recommended to lubricate (3) a thin layer of silicone thermal conductive paste before the assembly, which is not a mandatory condition for installation.

Install the thyristor (3), the second part of the cooler, the fiberglass insulator and the thrust washer.

To thread the traverse (4) and evenly tighten the nuts. Make sure no misalignment and evenness of the contact surfaces.

When the parts are sufficiently clamped but moveable, we recommend placing the cooler on a flat surface and checking the tolerance for parallelism of the overall adjacent plane of the surfaces (5).

Clamp each nut in turn (about a quarter turn) to the stop (6). The amount of deflection of the crosshead determines whether the achieved clamping force corresponds to the required one.

After installation, the fasteners (nuts and washers) must be additionally secured against corrosion.


Tips and recommendations for power thyristors:

The power thyristors should not be operated for long periods of time at their limit load for all parameters. In this case, the safety factor is determined by the required degree of reliability of the device.

Replace a failed power thyristor with a thyristor that matches the parameters of the one being replaced.

Supercooling must be provided when operating in an environment with an elevated ambient temperature.

Periodic cleaning of power thyristors and coolers to remove dust and contaminants is recommended to ensure proper heat dissipation.

Inductive current dividers (often twisted toroidal wire) should be used to equalize currents between power thyristors connected in parallel. The most popular connection methods are closed circuit, common coil circuit, or power thyristor. The efficiency of current dividers in this case is determined by the cross section of the magnetic wire.

Prevention of voltage unbalance when power thyristors are connected in series is achieved by using shunt resistors connected in parallel with each thyristor. Voltage equalization in transient conditions is provided by connecting capacitors in parallel to each thyristor.

Device under voltage

It is strictly forbidden to touch power thyristors under high voltage during operation.
