SHINKO OSR OVER SPEED TRIP RELAY

What is an Over Speed Trip Relay?

An over speed trip relay is a protective device used to check the speed of rotating equipment. If the system goes beyond the set speed limit, the relay activates a shutdown to avoid mechanical damage or safety risks. Imagine it as a watchdog that continuously monitors for any indication that your equipment is running wild.

Introducing the SHINKO OSR Over Speed Trip Relay

The SHINKO OSR is a highly engineered over speed trip relay designed to perform in challenging applications. Produced by SHINKO Electric Co., Ltd., the product is renowned for its:

• High-speed accuracy
• Fast response time
• Robust fail-safe design
• Simple maintenance and installation

It’s widely used in marine engines, diesel generator sets, turbines, and other rotary equipment where speed control is crucial to performance and safety.

Key Specifications of the SHINKO OSR Relay

Adjustable Speed Setting:
Lets you set accurate speed limits according to the particular machinery need.

Electromechanical Reliability:
Has both mechanical and electrical parts to ensure greater safety and quicker response.

Vibration Resistance:
Designed rugged to cope with vibration-prone environments, particularly on ships or heavy-duty plants.

Compact Design:
Conserve space without compromising performance—perfect for compact panels and engine rooms.

Fail-Safe Operation
In the event of failure or malfunction, the device automatically goes to a safe state so that there will be no accidents.

How Does the SHINKO OSR Operate?

The SHINKO OSR operates by monitoring equipment rotational speed continuously with a pickup sensor or magnetic trigger. Below is a simplified explanation of how it works:

Speed Detection:
A magnetic pickup sensor measures the RPM of a rotating gear or shaft.

Signal Processing:
The signal of speed is sent to the OSR relay, which checks it against a predetermined threshold.

Trip Action:
When the RPM goes beyond the threshold, the relay initiates a trip action—reducing fuel supply, deactivating the system, or initiating an alarm.

Reset Mechanism:
Once the fault has been cleared, the relay can be restarted manually or automatically, depending on system design.

Applications of SHINKO OSR

This relay finds particular use in situations where overspeed conditions are likely to result in catastrophic failure. Uses are:

Marine Main Engines & Auxiliary Engines
Prevents occurrence of overspeed conditions during maneuvering or instant load changes.

Diesel Generator Sets
Enables safe operation and automatic shut-down in the event of failure.

Steam or Gas Turbines
guards high-speed revolving turbines against unsafe speed excursions.

Industrial Compressors and Pumps
Provides an added degree of safety to guarantee maximum operating speed.
