FDZ32-12 series outdoor high-pressure vacuum automatic sectionalizerDetailed product description:

The FDZ32-12 series outdoor high-voltage vacuum automatic sectionalizer (hereinafter referred to as the sectionalizer) is used for 50Hz, 12kV three-phase distribution networks and is an intelligent switchgear. This segmenter, when used in conjunction with a recloser, can independently handle faults in the distribution network without relying on other control systems, and can minimize the area of power outages caused by faults. This product consists of a segmenter body and an electronic controller. The main body of the sectionalizer is an outdoor vacuum circuit breaker, which can be used to open and close load currents, circulating currents in the ring network, inductive currents of no-load transformers, and capacitive currents of capacitor banks (or cable lines); It can also close the short-circuit current and withstand the electric and thermal effects caused by short-circuit current. The incoming end of the segmenter body is equipped with a current transformer, which provides source information for the operation of the controller. The primary current of the current transformer can be made into 50-630A according to the user's requirements; the secondary current can be made into 5A or 1A.
During the period when a short circuit fault occurs in the distribution line and the recloser performs multiple reclosures in a predetermined manner, the electronic controller of the segmenter can remember the number of short-circuit currents passing through it. When the number of short-circuit currents passing through it reaches the set value, the segmenter automatically opens within the reclosing interval of the recloser without current or voltage, isolating the line that has experienced permanent faults. When the intact line continues to supply power, the isolation switch of this segmenter will automatically open, which not only reduces the range of power outages and avoids the extension and expansion of faults, but also marks the section where the fault occurred, providing convenience for searching for the fault point and shortening the power outage time. The main body of the segmenter is operated by a spring mechanism, which can be closed by storing energy with an electric motor (or human) and opened by an electromagnet (or human). The segmenter adopts a vacuum arc extinguishing device, with long electrical life, maintenance free, no explosion or fire hazard. Its overall layout is a floor standing pillar type, using an air silicone rubber composite insulation structure, light weight, small size, and suitable for installation on the pillar The power supply of the controller of the segmenter is installed separately from the main body.
