0936013247 is a multi-channel Safety Frequency Relay, also known as a frequency discriminator relay. It is widely used in electric power systems, electrical relay protection and intelligent devices for frequency monitoring and protection. It can be used in power generation, transmission, distribution, and end-user systems. It can be used to monitor the frequency of power systems, detect frequency changes, and accurately and quickly trip the circuit breaker in the event of a frequency change inside or outside the specified range.

The working principle of the 0936013247 is based on the thermoelectric effect. It has two sets of setting sockets for setting upper and lower frequency limits. The thermoelectric element provided on the relay is placed between the two setting sockets. The thermoelectric element is connected in series with a resistor and a selectable capacitor. The thermoelectric element is connected to two heat sink tubes of different temperatures, the temperature difference between the two heat sink tubes is directly proportional to the frequency of the input power line.

When the frequency of the input power line changes, the temperature difference between the two heat sink tubes also changes. When the temperature difference exceeds a certain threshold, the thermoelectric element fails and triggers the contact of the relay to trip the circuit breaker. The setting of the upper and lower limit frequencies is realized by adjusting the setting resistors and capacitors.

0936013247 has the characteristics of large capacity, low loss, stable and reliable performance, small size, light weight, low price, robust construction and ease of installation. It is suitable for automated system frequency monitoring and protection, and can trip in a few intervals when the frequency of the power line deviates from the specified range. It can also be used for remote frequency monitoring in computer communication systems.

In addition, the 0936013247 can also be used for frequency protection of generator-generator parallel units and generator-transformer parallel units, so as to realize automatic load balancing and generator protection. In the above applications, the 0936013247 can effectively protect power equipment from frequency anomaly or failure.

The 0936013247 is an indispensable protection device in the protective system of electric power, and has increasingly popular applications in various basic communication fields. It is widely used in various occasions such as coal mines, oil fields, machine rooms, subways, elevators, navigation systems, motor control, etc., which effectively ensure the personal safety and property security of a wide range of users.
