JSZV18-6, 10R type combined voltage transformer ring network cabinet use

JSZV18-6, 10R type combined voltage transformer ring network cabinet use

The JSZV18-6 and 10R type combined current transformers feature a fully enclosed structure insulated with epoxy resin, suitable for indoor use in power systems with a frequency of 50-60Hz and a rated voltage of 6 or 10KV and below, for three-phase voltage energy measurement, measurement, and relay protection. The newly developed primary winding includes fuse protection for the V-type connected voltage transformer, which has a large creepage distance, low magnetic flux density, and strong anti-resonance capability. The product performance meets the standards of GB/T 20840.1; 3 and IEC6044-2 'Voltage Transformers'. Using a V/V type connection, the fuse is installed inside the primary outgoing terminal for easy and quick replacement. The fuse current is matched with the short-circuit withstand capacity of the transformer, reducing space requirements. In addition to providing a secondary output of 100V for measurement, it can also supply a 220V output terminal for operating mechanisms as a power source, making it widely applicable in any switch cabinet and an ideal product for upgrades.

LZZBJ9-35D, 40.5D multi-winding large capacity current transformer

LZZBJ9-35D, 40.5D multi-winding large capacity current transformer

This type of current transformer is an epoxy resin cast pillar-type fully enclosed product, suitable for power systems in indoor installations with a rated frequency of 50Hz-60Hz and a rated voltage of 40.5kV and below, used for electric energy measurement, current measurement, and relay protection. This product complies with the standards IEC 60044-1-2016 and GB/T 20840.2-2014 'Current Transformers'. With the transition to electrical intelligence and networking, especially in substations where current transformers have multiple secondary circuits and protections, it not only requires self-differential protection but also needs to cooperate with upper and lower level differential protection to form multiple interlocking protections, as well as meet the demand for large capacity of secondary equipment. This product can combine 4-6 secondary windings, achieving a conventional capacity of 2-3 times when using 4 secondary windings. It features a small size, lightweight, suitable for arrangement in any position and direction, and requires no special maintenance, only regular cleaning of surface dirt.
