OVR-38/800-16 3-Phase Recloser - Product

Product Overview

The OVR - 38/800 - 16 three - phase recloser is an outdoor high - voltage distribution switchgear with a rated voltage of 38kV and a three - phase alternating current of 50/60Hz. The recloser is used for overhead lines and substations. Like a circuit breaker, it can cut off normal and fault currents. It is equipped with sampling sensors and controllers as protection and control devices. When a fault occurs on the line, it can quickly trip for protection to avoid longer line power outages, with up to 4 reclosing operations. Instantaneous faults can achieve quick power - on through reclosing. It is suitable for substation outgoing switches, and can cooperate with reclosers and sectionalizes. When a fault occurs on the line, it can automatically open and close multiple times for control, thus significantly improving power supply reliability.

It is suitable for working in harsh environments such as high altitudes, high salt fog, high humidity, and high dust.

Product Features

Built - in high - precision electronic sensors: It has the characteristics of a wide measurement range, good linearity, strong anti - interference ability, high measurement accuracy, small size, and high reliability.
Sealed poles: The vacuum arc - quenching chamber, current and voltage sensors, main conductive circuits, and some insulating support parts are integrally sealed with epoxy resin through the APG process, having good anti - condensation performance and mechanical strength.
Dual - side voltage sampling: It has the function of voltage sampling on both the power supply side and the load side.
Applicable scenarios: It can be used for line segmentation, networking, branching, user boundaries, and other scenarios.
High - performance permanent magnet operating mechanism: It has a long mechanical life and can be operated by electric opening and closing.
The main body case is made of 3mm thick high - quality stainless steel plates: It has high strength and strong corrosion resistance.
