Product description

The ProTech-GII is an overspeed safety device designed to safely shut down steam, gas and hydro turbines of all sizes when an overspeed or over-acceleration event is detected.

trait

Acceleration detection

The 8237-1600 ProTech-GII can also be configured to protect turbines from high acceleration events. The derivative of the speed signal is used to detect the turbine acceleration and issue the relevant trip command.

Main control board inspection

The 8237-1600 Speed sensor inputs in each module use a special MPU open-wire detection circuit to verify that the MPU is properly connected prior to turbine operation, and a special stall detection logic to verify MPU function during turbine operation.

Automatic overspeed test program

Alternatively, ProTech-GII can be configured to periodically perform overspeed tests on each module, and then record and report the test results. With this test routine, each module uses an internal frequency generator to simulate overspeed conditions to complete its test sequence.

Resistance to sulfur pollution

ProTech-GII uses a special conformal coating material, which has excellent long-term protection against H2S and SO2 gases, and its grade meets the international standard IEC 721-3-3 1994- Environmental grade 3C2.

An overspeed safety device is a safety device used to protect equipment or systems from damage or failure due to overspeed operation. It is commonly used in mechanical equipment, vehicles, industrial automation systems, etc.

The 8237-1600 Overspeed safety device can protect equipment or systems by monitoring the rotational speed or speed of the equipment or system and triggering a safety mechanism if the set safe speed is exceeded. The overspeed safety device may include components such as sensors, controllers and actuators.

The operating principle of the 8237-1600 speed safety device may be mechanical, electrical or electronic. Some common speed safety devices include:

1. Mechanical overspeed safety device: such as centrifugal overspeed switch, ratchet overspeed switch, etc., they monitor the speed or speed through the mechanical structure, and trigger the safety mechanism when the set safety speed is exceeded.

(2) Electrical overspeed safety devices: such as electromagnetic overspeed switches, photoelectric overspeed switches, etc., they monitor the speed or speed through electrical signals, and trigger the safety mechanism when the set safety speed is exceeded.

3. Electronic overspeed safety devices: such as microcontrollers, sensors and actuators, which monitor the speed or speed through electronic signals and trigger the safety mechanism when the set safe speed is exceeded.

Overall, overspeed safety devices are an important safety device that provides reliable overspeed protection and helps protect equipment and systems from damage or failure due to overspeed operation.
