  【概述】

  PV1-12戶內真空斷路器是適用于12KV、三相交流50/60HZ電力系統的戶內開關設備,可廣泛運用于能源及基礎設施、工業、商業及民用建筑領域的中壓配電網保護及控制,特別適用于高壓/中壓、中壓/中壓、中壓/低壓的變配電中。該產品主回路采用固封極柱,有利于提高斷路器的環境適應性和絕緣可靠性,改進機構設計,延長機械壽命,提高機械可靠性,使得斷路器的免維護成為可能。由于斷路器的特殊優越性,非常適合于要求額定工作電流的頻繁操作,或多次開關短路的場所。

  斷路器采用操作機構與斷路器本體一體化的設計,既可作為固定單元,也可配用專用推進機構,組成手推式單元使用,其中固定式斷路器可以增加相應的機械聯鎖,以滿足KYN28,XGN66等中壓開關柜的需要。產品設計符合國家和行業相關標準,滿足開關柜的“五防”保護功能。

  【Overview】

  PV1-12 indoor is applicable to 12 kv vacuum circuit breaker, three-phase AC 50/60 HZ indoor switchgear equipment of power system, which can be widely used in energy and infrastructure, industrial, commercial and civil construction in the field of medium voltage distribution network protection and control, especially suitable for high/medium voltage, medium voltage/medium voltage, medium voltage/low voltage distribution. The product main circuit adopts the enclosed column, to improve the environmental adaptability and insulation reliability of circuit breaker, the improvement on the design of institutions, prolong mechanical life, improve the mechanical reliability, making it possible to breaker maintenance free. Because of the special superiority of circuit breaker, which is very suitable for requirements of rated current of frequent operation, or multiple switch short circuit.

  Circuit breaker operating mechanism and the design of the circuit breaker adopt integration design, can be used as the fixed unit, also can with special propulsion mechanism, composition of hand push type unit is used, including fixed circuit breaker can increase the corresponding mechanical interlocking, to meet KYN28, XGN66 such as the needs of the medium voltage switchgear. Product design in line with national and industry standards, meet the "five prevention" protection switch cabinet.

  【特點】

  1、 性能穩定可靠:固封極柱采用高性能環氧樹脂材料,通過自動壓力凝膠工藝,將真空滅弧室及上

  下出線固封在一起,減少了斷路器的調整環節,提高了裝配質量和機械可靠性;

  命高達30000次,在每個操作循環內可實現免維護,適合頻繁操作;

  3、耐腐蝕力優良:機構零件采用先進的表面處理工藝,零件抗污、抗腐蝕能力更強,機械穩定性更高;

  4、導電性能優異:采用固體封裝絕緣技術,減少了導電部位的氧化,降低了回路電阻,提高了主回路的可靠性,避免了不必要的溫升;

  5、絕緣性能高:一次主導電回路采用APG加工工藝,使環氧樹脂與真空滅弧室完美結合,能有效防止潮濕、污穢、凝露等外界不良環境對絕緣性能的損害,一次導電回路免維護;

  6、互換性能好:外形尺寸與ZN63A(VS1)型產品相同,可實現可靠無縫互換;

  7、電器元件選用優質可靠的品牌產品,確??刂频目煽?、穩定性;

  8、具備E2-C2-M2高標準斷路器性能,通過權威檢測機構1.1倍額定電流溫升試驗。

  【Characteristics】

  1. Stable and reliable performance, solid column with high performance epoxy resin materials, sealing by automatic pressure gel technology, the vacuum arcing chamber and on

  To qualify under the enclosed together, reducing the circuit breaker adjustment, improve the quality of the assembly and mechanical reliability;

  2. Machinery, long service life: the product adopts automated assembly and testing product line, make the product has a very high reliability and mechanical life of circuit breaker

  Life as much as 30000 times, can be realized in every operation cycle maintenance free, suitable for frequent operation;

  3. Good corrosion resistance, mechanism parts adopt advanced surface treatment technology, parts stronger fouling resistance, corrosion resistant ability, higher mechanical stability;

  4. Conductive performance: using solid encapsulation insulation technology, reduce the oxidation of the conductive parts, reduces the loop resistance, improve the reliability of the main circuit, to avoid the unnecessary temperature rise;

  5. High insulation performance: a main electric circuit USES the APG process, make the perfect combination with epoxy resin vacuum arcing chamber, can effectively prevent as damp, filthy and condensation outside bad environment such as the damage to the insulation performance, a conductive loop free maintenance;

  6. Good for the interchange function: the dimensions with ZN63A (VS1) products are the same, which can realize reliable seamless interchange;

  7. Reliable brand electrical components selection of quality products, to ensure the reliability, stability of the control;

  8. The high level of circuit breaker with E2 - C2 - M2, by authoritative testing institutions to 1.1 times the rated current temperature rise test.
