ZMD on load tap changer
Product Description
ZMD on-load tap-changer is a high-quality, high-tech product through digestion, absorbing and introducing technology,combined with years of on-load tap-changer production and management. It is suitable for voltages below 252kV and a maximum rated current of three-phase 300A. , 500A, 600A,1000A, single-phase 300A,500A, 600A, 800A, 1200A, 1500A, power transformer or industrial transformer with rated frequency of 50 or 60Hz.
Suitable for three-phase Y-connection neutral point voltage regulation,single-phase voltage regulation at any part.

Type designation
Product features
The diverter switch of the ZMDIII100A on-load tap changer adopts a four-resistance excessive tail push compensation switching mechanism, which generates three arcs during switching (double-resistor type generates two arcs), and the switching capacity allocated to each arc is low, which improves the switching capacity. In addition, the recovery voltage at the fracture of the arc contact is low, which is beneficial to extinguishing the arc and improves the level voltage.
The lead wire of the tap selector adopts a mature outer sheath lead method. The central insulating column and the contact ring are not only simple in structure, but also have a large insulation margin. Compared with the external lead method, each phase reduces two lead-out rings and lead-out contacts, and shortens the axial size of the tap selector.
Conversion selector: Compared with the existing cylindrical tap selector structure, its moving contact system reduces movement conversion links,reduces the transposition connection of conductors, and improves the contact and positioning reliability of the conversion selector. Design according to the coarse and fine adjustment of the insulation level. It can be used for both positive and negative adjustment transformers and coarse and fine adjustment transformers.
The moving contact of the tap selector of the ZMDIII1000A OLTC adopts double-layer multi point contact, with reliable contact, low resistance,low temperature rise, large current carrying and strong short-circuit resistance.
The tap selector structure adopts a semi-closed cylindrical structure composed of an insulating cylinder and an arc-shaped insulating plate.
Strong anti-traction ability. It is not easy to be deformed or damaged during installation and transportation;the structure is compact, the radial installation size is small, and the space is small.
