Phase Control Thyristors OLD Part Number WESTCODE Replacement

Power phase control thyristors, also known as Thyristor SCR (Silicon Controlled Rectifier), in disc design are press pack type general-purpose thyristors, regulating and converting DC and AC currents up to 5946A in circuits with voltages to 4500V (depends on the thyristor type).

Thyristors ATDN AS ENERGITM are a replacement, analog, alternative for presspacks electrical triggered thyristors WESTCODE.

"Air-cooled heatsinks O series for disc devices", "Air heatsink SF series", "Water heatsink SS series" for thyristor cooling are also available to order.

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 contacts (leads), 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 traverse 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.

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