JDZX10-36 Voltage Transformer

Product Overview

JDZX10-36 voltage transformer, epoxy resin casting and single pole insulated VT, is widely used indoor for measuring current, electric energy and protective relaying in the isolated neutral system with the frequency 50-60Hz and highest voltage for equipment 36 kV.

Feature：

• High-Precision Voltage Transformation: Uses high-permeability premium silicon steel for the core and meticulously wound coils to accurately convert 36kV high voltage. With a metering accuracy of up to class 0.2, it delivers extremely precise low-voltage signals for energy metering and power system monitoring, meeting high-precision voltage data requirements and providing reliable data support for stable power system operation.

• Adaptation to Harsh Indoor Environments: Specifically designed for indoor use with a fully enclosed structure. Internal windings and core are tightly encapsulated via epoxy resin vacuum casting, effectively resisting interference from dust, moisture, etc. It operates stably in indoor environments with temperatures ranging from -5℃ to 40℃ and relative humidity up to 90%, making it ideal for enclosed spaces like indoor substations and switch cabinets.

• Excellent Insulation Performance: Features a robust insulation layer formed by epoxy resin casting, boasting high insulation strength to withstand 36kV rated voltage and potential operational overvoltage impacts. Its partial discharge level is extremely low (typically ≤10pC), significantly reducing the risk of insulation aging and faults caused by partial discharge, extending service life and ensuring safe, stable power system operation.

• Compact and Lightweight Design: With an overall compact structure, it is significantly smaller in volume and lighter in weight compared to traditional similar products. This design not only saves valuable indoor installation space but also reduces labor costs and difficulties during installation, allowing flexible and convenient installation in indoor power facilities with limited space.

• Easy Installation and Maintenance: Complies with standardized installation dimensions, supporting multiple mounting methods such as horizontal and vertical installation. The mounting holes are reasonably positioned for easy connection and fixation with mounting brackets or cabinets. It offers flexible outlet methods, easily achievable via direct outlet or cable connection. Moreover, daily maintenance requires no complex debugging procedures, effectively reducing maintenance time and costs and improving the operational efficiency of power systems.

Pagpakilala sa Produkto

Ang JDZX10-36 voltage transformer, na may epoxy resin casting at single pole insulated VT, ay malawakang ginagamit sa loob ng building para sa pagsukat ng kasalukuyan, elektrikong enerhiya, at protective relaying sa isolated neutral system na may frequency 50-60Hz at pinakamataas na voltaje para sa equipment na 36 kV.

Pangunahing Katangian：

• Matinding Tumpak na Pagbabago ng Voltaje: Gumagamit ng mataas na permeabilidad na premium silicon steel para sa core at matinding inihanda ang mga coil upang tumpaking i-convert ang 36kV na mataas na voltaje. May akurasya ng pag-measure hanggang sa class 0.2, nagbibigay ito ng napakatumpak na mababang voltaje na signal para sa pagsukat ng enerhiya at monitoring ng power system, na sumasagot sa matinding tumpak na pangangailangan ng data ng voltaje at nagbibigay ng mapagkakatiwalaang suporta ng data para sa matatag na operasyon ng power system.

• Pag-aangkop sa Mahigpit na Indoor Environment: Espesyal na disenyo para sa paggamit sa loob ng building na may buong saradong struktura. Ang mga internal winding at core ay matinding nakapaloob sa pamamagitan ng epoxy resin vacuum casting, na matutugunan nito ang interference mula sa alikabok, basa, atbp. Ito ay gumagana nang matatag sa mga environment sa loob ng building na may temperatura na nasa range mula -5℃ hanggang 40℃ at relative humidity hanggang 90%, na ideyal para sa mga saradong lugar tulad ng indoor substations at switch cabinets.

• Kamangha-manghang Performance ng Insulation: May matibay na insulation layer na nabuo sa pamamagitan ng epoxy resin casting, na may mataas na lakas ng insulation upang matiis ang 36kV na rated voltage at potensyal na operational overvoltage impacts. Ang level ng partial discharge nito ay napakababa (typical ≤10pC), na siyang nagsasanggalang nang matindi sa pangingitlog ng insulation at mga kamalian dahil sa partial discharge, na nagpapahaba ng serbisyo at nag-uugnay sa ligtas at matatag na operasyon ng power system.

• Compact at Mababang Design: May buong compact na struktura, ito ay mas maliit sa volume at mas mababa sa timbang kumpara sa mga tradisyonal na katulad na produkto. Ang disenyo na ito ay hindi lamang nakakatipid sa mahalagang espasyo ng instalasyon sa loob ng building kundi pati na rin nagbabawas ng gastos sa labor at hirap sa panahon ng instalasyon, na nagbibigay ng flexible at convenient na instalasyon sa mga indoor power facilities na may limitadong espasyo.

• Madaling Instalasyon at Pagsasauli: Sumusunod sa standard na dimensyon ng instalasyon, na sumusuporta sa maraming paraan ng pag-mount tulad ng horizontal at vertical na instalasyon. Ang mga butas ng mount ay maaring maayos na posisyonin para sa madaling koneksyon at pagsasara sa mga bracket o cabinet. Ito ay nagbibigay ng flexible na paraan ng outlet, na maaaring makamit sa pamamagitan ng direkta na outlet o cable connection. Bukod dito, ang pang-araw-araw na pagsasauli ay hindi nangangailangan ng komplikadong proseso ng debugging, na matutugunan nito ang pagbawas ng oras at gastos sa pagsasauli at pagpapabuti sa operational efficiency ng power system.
