Industrial Equipment: UMQ-4732-A Application Field and Working Principle

The UMQ-4732-A is an advanced industrial equipment model manufactured to provide reliable and precise electric power solutions. It is widely used in various industrial fields, such as power system control, supporting equipment, and automation of production processes. This paper elaborates on its application field and working principle.

Application Field

The UMQ-4732-A has a number of beneficial characteristics that make it an ideal choice for usage in a variety of electrical engineering and process automation applications. The device provides mounted-mounted and DIN-rail type mounting, with up to 4 breaker poles and 0.75kV current rating and power rating. It has high-quality plastic shell, which is highly resistive to heat, oil, dust, and water. The UMQ-4732-A also offers resistance to ultraviolet radiation and has a presence of trip contactor and relay functions.

The UMQ-4732-A is applicable for AC and DC power systems, including other components of power plants, power station, substation, load center and switchgear cabinet. It is a suitable choice for fault signaling, motor control applications, motor selector operations, and shut-off control. Furthermore, this industrial equipment model offers cutting edge features such as progressive extension timings, dual speed transfer, and selective reset.

Working Principle

The UMQ-4732-A is an AC voltage monitoring device and is powered by a tri-level power input voltage. It is designed for use in situations involving a two-level AC voltage system, and utilizes a dynamic relaying algorithm for monitoring the input voltage. In a two-level system, the voltage is constituted by two levels of voltage. The first level consists of the normal operating voltage and the second level consists of a lower voltage, termed as the fault level. The fault level is also known as the out-of-tolerance level.

When in operation, the UMQ-4732-A continuously monitors the input voltage level of the system. In the event of an out-of-tolerance voltage level, the device immediately sends a diagnostic signal to alert the necessary personnel of the problem. The UMQ-4732-A also provides a second level of protection by supplying a circuit breaker function which will trip the breaker automatically in the event of an out-of-tolerance voltage level.

Furthermore, the UMQ-4732-A is designed for situations in which the two level system is exchanged due to maintenance activities or interruption to service. In case of such exchange, the device will sense the new voltage levels, adjust its settings accordingly, and resume normal operation.

Conclusion

The UMQ-4732-A is an advanced industrial equipment model with a variety of beneficial characteristics for usage in electrical engineering and process automation applications. Its application field covers a wide range of power systems, while its working principle involves a dynamic relaying algorithm for monitoring input voltage. The device has features such as cutting-edge progressive extension timings, dual speed transfer, and selective reset, making it a highly reliable and efficient choice.
