A unidade serve a m\u00faltiplas fun\u00e7\u00f5es, incluindo medi\u00e7\u00e3o de tens\u00e3o, medi\u00e7\u00e3o de energia, prote\u00e7\u00e3o de rel\u00e9 e substitui\u00e7\u00e3o de fus\u00edveis. \u00c9 usado principalmente em m\u00e9dia tens\u00e3o interna switchgear<\/a> (por exemplo, s\u00e9rie KYN28) para monitoramento de tens\u00e3o, supervis\u00e3o de isolamento e aquisi\u00e7\u00e3o de sinais de prote\u00e7\u00e3o, sendo amplamente aplicado em sistemas de distribui\u00e7\u00e3o de 10kV, subesta\u00e7\u00f5es pr\u00e9-fabricadas e unidades de anel.<\/p>\n\n\n\n

Principais Recursos do Produto<\/h3>\n\n\n\n

Isolamento e Desempenho El\u00e9trico<\/h3>\n\n\n\n

Fully Enclosed Epoxy Resin Cast Insulation: The entire unit is formed by vacuum casting with epoxy resin, resulting in a void-free interior with excellent insulation performance. It withstands the 12kV system operating voltage and passes power-frequency and impulse withstand voltage tests. The insulation has a long service life with no leakage or oil contamination risk, making it suitable for oil-free indoor distribution applications.<\/p>\n\n\n\n

Integrated Current-Limiting Protection: The built-in current-limiting resistor replaces conventional fuses to provide overcurrent protection for the voltage transformer, preventing damage from secondary circuit short circuits or overcurrent events, improving system operational reliability, and simplifying secondary circuit design within the switchgear.<\/p>\n\n\n\n

Wide Voltage Ratio Compatibility: Supports multiple voltage ratios (e.g., 10\/0.1kV, 10\/0.1\/0.1kV, etc.) with simultaneous multi-tap secondary outputs for metering, protection, and insulation supervision. Accuracy classes are customizable (0.2\/0.5\/1 \/ 3P\/6P, etc.) to meet diverse application requirements.<\/p>\n\n\n\n

Low Partial Discharge Design: Advanced casting process ensures partial discharge level \u226410pC, preventing insulation aging caused by long-term partial discharge activity and improving long-term operational reliability.<\/p>\n\n\n\n

Estrutura e Caracter\u00edsticas de Instala\u00e7\u00e3o<\/h3>\n\n\n\n

Fully Enclosed Dry-Type Construction: The integrally cast structure has no exposed core or live parts, with a protection degree of IP20, no fire hazard, compact dimensions, small footprint, and compatibility with standard switchgear installation dimensions.<\/p>\n\n\n\n

Dual Model Design: JDZ10-10 is the single-winding type; JDZX10-10 is the residual-voltage winding type (for insulation supervision). Models can be selected flexibly based on system requirements to accommodate different switchgear types and protection schemes.<\/p>\n\n\n\n

Clear Terminal Identification: Primary high-voltage terminals are clearly labeled; secondary terminals are protected by transparent covers for convenient wiring, preventing miswiring and short circuits, while also guarding against accidental secondary circuit short circuits. Terminal layout complies with switchgear internal wiring standards.<\/p>\n\n\n\n

Flexible Installation: The bottom metal mounting base includes fixing holes to support bolted installation. Compatible with horizontal indoor switchgear mounting, it provides secure installation with excellent vibration resistance for compact panel arrangements.<\/p>\n\n\n\n

Funcionalidades Operacionais e de Manuten\u00e7\u00e3o<\/h3>\n\n\n\n

Opera\u00e7\u00e3o sem Manuten\u00e7\u00e3o: A constru\u00e7\u00e3o seca e isenta de \u00f3leo elimina riscos de vazamento e inc\u00eandio. O corpo fundido em resina ep\u00f3xi possui alta resist\u00eancia mec\u00e2nica, resist\u00eancia ao impacto e resist\u00eancia ao envelhecimento, permitindo opera\u00e7\u00e3o de longo prazo sem manuten\u00e7\u00e3o, reduzindo custos de O&M e eliminando a necessidade de substitui\u00e7\u00e3o peri\u00f3dica de fus\u00edveis.<\/p>\n\n\n\n

Wide Temperature Operation: Suitable for ambient temperatures from -30\u00b0C to +70\u00b0C. Epoxy resin performance remains stable across temperature extremes with no risk of embrittlement or deformation, accommodating diverse regional climate conditions.<\/p>\n\n\n\n

High-Reliability Design: Windings are wound with enameled copper wire; the core is laminated from high-quality silicon steel sheets. The unit operates with low losses and low heat generation, withstands system switching overvoltages and lightning impulse overvoltages, and incorporates a stable current-limiting resistor to ensure reliable protection performance.<\/p>\n\n\n\n

Requisitos de Instala\u00e7\u00e3o<\/h3>\n\n\n\n

Pre-Installation Inspection: Inspect the voltage transformer for external damage \u2014 the cast body shall be free of cracks, voids, and breakage; terminal markings shall be clear and all accessories present. Verify that the model, specification, voltage ratio, rated current, and current-limiting protection function conform to design requirements.<\/p>\n\n\n\n

Mechanical Fixing: Position the voltage transformer at the designated mounting location within the switchgear and secure it through the bottom mounting holes using bolts. Ensure the installation is firm with no looseness or misalignment, and that the mounting surface is level to avoid eccentric loading.<\/p>\n\n\n\n

Primary (High-Voltage) Side Wiring: Connect the high-voltage terminals per design requirements, ensuring tight connections with good contact. Maintain adequate safety clearances between the high-voltage leads and earthed parts or other live parts to prevent flashover.<\/p>\n\n\n\n

Secondary (Low-Voltage) Side Wiring: Connect the low-voltage terminals according to markings, with separate wiring for metering, protection, and insulation supervision circuits. Ensure correct wiring. The secondary circuit must never be short-circuited and must be reliably earthed (single-point earthing) to prevent overvoltage.<\/p>\n\n\n\n

Insulation Testing: After installation, measure the insulation resistance (HV to LV and earth; LV to earth) to confirm insulation performance meets requirements. Verify secondary circuit wiring is correct with no short circuits or open circuits.<\/p>\n\n\n\n

Pontos Chave de Manuten\u00e7\u00e3o<\/h3>\n\n\n\n

Periodically inspect the voltage transformer externally \u2014 the cast body shall show no cracks, damage, or discharge marks; primary terminals shall show no looseness or oxidation; secondary terminal protective covers shall be intact.<\/p>\n\n\n\n

Periodically inspect primary and secondary connections for tightness, with no signs of overheating or discoloration. Verify secondary circuit earthing is reliable with no short circuit or open circuit risk.<\/p>\n\n\n\n

Periodically test insulation resistance and voltage ratio to confirm metering and protection accuracy meets requirements, and verify that the current-limiting protection function is operating correctly.<\/p>\n\n\n\n

Clean dust and contamination from the transformer surface; prevent oil or corrosive substances from adhering; keep the equipment dry and clean.<\/p>\n\n\n\n

In the event of cracks, discharge, overheating, voltage ratio deviation, or protection function failure, de-energize immediately for inspection and replace the equipment if necessary. Do not operate a faulty unit.<\/p>\n\n\n\n

Precau\u00e7\u00f5es<\/h3>\n\n\n\n

Secondary windings must never be short-circuited. Should a secondary circuit short circuit occur during operation, the current-limiting resistor will act to protect the equipment; however, the fault must still be investigated and cleared promptly. During maintenance, the secondary circuit must be reliably open-circuited and earthed.<\/p>\n\n\n\n

Avoid mechanical impacts or shocks to the cast body during installation to prevent epoxy resin cracking or insulation damage that would compromise dielectric performance.<\/p>\n\n\n\n

Primary side wiring must use dedicated insulated leads with adequate safety clearances maintained from earthed parts and other live parts to prevent phase-to-phase or phase-to-earth flashover.<\/p>\n\n\n\n

Equipment earthing must be reliable \u2014 the base earthing terminal must be securely bonded to the switchgear earthing busbar to ensure proper equipment earthing.<\/p>\n\n\n\n

During storage, place the unit in a dry, well-ventilated, cool environment away from direct sunlight, high temperatures, humidity, and compressive loads to prevent aging or deformation of the cast body.<\/p>\n\n\n\n

A instala\u00e7\u00e3o, a coloca\u00e7\u00e3o em funcionamento e a manuten\u00e7\u00e3o devem ser realizadas por pessoal el\u00e9trico qualificado, em estrita conformidade com os procedimentos operacionais de seguran\u00e7a el\u00e9trica.<\/p>\n\n\n\n
