以上要求应符合标准。
特殊要求等。
山西干式变压器设计计算的任务,就是根据上述技术规范,按照有关国家标准如《山西干式变压器》及《三相油浸式山西干式变压器技术参数和要求》和部标准等,确定山西干式变压器电磁负载、几何尺寸和电、热、机械方面的性能数据,以满足使用部门的要求。要有良好的工艺性,使其制造简单,产品的价格应便宜.要求设计者要综合考虑上述各种因素,进行多方案比较分析,选取佳方案。
Transformer design calculation tasks
First, to meet the relevant national standards and the requirements of other relevant standards, but also meet the requirements of the contract, usually transformer contract should include the following technical specifications.
Change a few device types
Number of phases, the number of windings, auto, step-up or step-down
The rated capacity of the transformer
Rated capacity of each winding three-winding transformer or autotransformer rated capacity, or in different cooling mode.
Transformer cooling
The oil from cold; air-cooled oil-immersed; forced oil circulation air-cooled; forced oil circulation water cooling; forced oil-oriented cycle air-cooled; forced oil-oriented loop water cooling.
Transformer rated voltage regulator
Rated voltage of high-voltage, medium-voltage or low voltage, load voltage regulation or no excitation voltage and its sub-range tap class. OLTC should indicate the neutral point regulator or line-side regulator.
The impedance of the voltage华盈非晶合金变压器有限公司 value of the transformer.
Connection symbol.
Transformer load loss and load loss and no-load current.
Technical Data bushing type current transformer.
Rated frequency.
The altitude of the installation site.
The above requirements should be consistent with the standards.
Special requirements.
The transformer design task, that is, according to the technical specifications in accordance with the relevant national standards, such as power transformers "and" three-phase oil-immersed power transformers technical parameters and requirements and standards, determine transformer electromagnetic load, geometry and electrical thermal and mechanical performance data to meet the requirements of the user departments. Have a good process, m传 真:0635-8888109aking it simple manufacturing, the price of the product should be cheap. Designers and comprehensive consideration of the above factors, comparative analysis of the multi-program, and select the best solution.
