The WOUV-125DC is a type of protection relay and system that offers extraordinary protections to electronic equipment. It functions by sensing abnormal conditions and sending a signal to various equipment disconnection or control devices. This provides crucial protection for electronic equipment and prevents damage due to electrical hazards. This article will discuss the WOUV-125DC application field, working principle, and structure.

Application Field

The WOUV-125DC can be used in a wide range of applications that involve the protection of electrical equipment from a variety of hazards. One of the main areas where it can be used is in the protection of switchgear and other associated equipment. This includes protection against overloads, short circuits, and other potential faults. Additionally, it can also be used to protect against overloads in motor control circuits.

Other applications where the WOUV-125DC can be used include industrial automation, phone bridges, and household applications. In industrial automation, it is used to protect various machines and control circuits from faults. In phone bridges, it can be used to protect the system from overloads due to external conditions. And in household applications, it can be used to protect equipment from overloads or signals that can cause damage.

Working Principle

The WOUV-125DC works on the basis of a self-actuated relay system. Its main components are an AC or DC power supply, power relays, and control relays. When the power is applied to the power relays, the control relays detect any fault conditions and initiate tripping. If an overload is detected, the power relay trips and sends a signal to the control relay to adjust the current flow. The control relays can also detect short circuits, reverse phase, phase imbalance, and other fault conditions and will initiate tripping.

The WOUV-125DC protection relay also offers different levels of protection, including three-phase and single-phase protection. In the three-phase protection mode, current sensors are used to detect three-phase unbalance and initiate tripping. In the single-phase protection mode, current sensors are used to detect single-phase faults and initiate tripping.

Structure

The WOUV-125DC protection relay is composed of several components, including a relay system, a control relay, current sensors, trip circuitry, and an alarm system. The relay system consists of the power relays and the control relays. The control relays are responsible for the operation of the system and their main functions are to detect and initiate tripping when an excessive current is detected. The current sensors are used to detect current abnormalities and generate a signal for the control relays. Trip circuitry is used to break the power supply when an overload or other fault situation is detected. And finally, the alarm system is used to indicate any fault situations and will alert personnel if there is a problem.

The WOUV-125DC is a highly reliable protection relay and system that can provide robust protection to electronic equipment. Its application field is vast and it can be used for both industrial and home applications. It uses a self-actuated relay system to detect abnormal conditions and initiate tripping. This system includes a relay system, a control relay, current sensors, trip circuitry, and an alarm system. With its broad application, ranging from switchgear to industrial automation and home applications, the WOUV-125DC is the perfect solution for providing reliable and robust protection to electronic equipment.
