JLSZW high voltage electric power calculate box

imported resin, long-life
outdoor and high-accuracy

 

Description

This model volt and current combined transformer (another name is metering tank) is applied to three-phase circuit of AC50Hz and rated volt being 10-35kv, to be used for volt, current and energy measuring as well as protective relaying, it is suitable for urban, rural outdoor transformer substation as well as kinds of volt transformer substations in industrial enterprise. Adding active, reactive energy meter onto combined transformer is named as high volt power metering tank, this product could replace oil-immersed type combined transformer (metering tank).

Construction

This model transformer possesses outdoor epoxy resin casting type wholly-sealing and post type mechanism, for this product adopts outdoor epoxy resin for casting, so this product owns many advantages as anti-electric-arc, anti-ultraviolet radiation, anti-aging and long service life etc, this product is composed of two sets single-phase wholly insulated voltage transformers, forming "V/V" wiring mode, and two current transformers are separately series connected to A and C phase, moreover, the secondary coil of current transformer owns tap, through which gains different current changing. Based on three-phase two-component V/V wiring mode, the corresponding upgraded product is three-phase three-component Y/Y wiring high-volt power metering tank.

Technical data

Metering tank conforms to given provisions in GB17201-2006 <combined transformed>

Current transformer conforms to given provisions in GBI208-2006 <current transformed> ;

Voltage transformer conforms to given provisions in GBI207-2006 <voltage transformed> ;

The zinc oxide arrester must be installed at certain position with less-than-one meter distance away from product's installation place, for lightning protection.
