The seres of outdoor voltage transformers are full cast-resin insulated usedin outdoor. They are used for metering electric energy;voltage control and relayprotection in the electric system up to rated frequency 50Hz or 60Hz and raetedvoltage 35kV.The transformers can be executed according to the standards IEC186and GB1207-2006.
二、型號含義
三、結(jié)構(gòu)簡介
本系列電壓互感器戶外環(huán)氧樹脂澆注全封閉結(jié)構(gòu),具有耐電弧、耐紫外線、耐老化、爬電距離大，局部放電量小、抗過電壓能力強等特點。JDZXW-35(R)為單相、相對地連接，JDZXW-35(R)有兩個二次繞組，即電能測量與電壓監(jiān)控分開;JDZXW-35(R)為單相、相對地連接，一次A端接相線,N端接地，JDZXW-35(R)有三個二次繞組，即電能測量、電壓監(jiān)控和繼電保護分開。
This types of voltage transformers are full en-closed structure of outdoorcast-
resin insulation. They have much merit,such as :electric arc resistance,ultraviolet rayand aging resistance long creep-age distance,little partial discharge and large caliberof resistance to over voltage.
JDZXW-35(R) is a single-phase transformer connected between
phase.The JDZF35W2 has two secondary windings. It is separation of energymeasuring form voltage. Monitoring;The JDZXW-35 (R),is also single-phasetransformer connected between phase to ground. The primary A terminal isconnected with phase wire, the N terminal is earthen.The JDZX W-35(R) hasthree secondary windings. It is separation of energy measuring form voltagemintoring and relay protecting.
