AD02 ABB 主要作用是將高電流轉(zhuǎn)換成低電流

電流互感器是一種特殊的電氣設備，AD02的主要作用是將高電流轉(zhuǎn)換成低電流，以便于進行測量或保護。這樣可以在不直接接觸高電流的情況下，通過測量低電流來得知高電流的情況，從而確保人員的安全和設備的穩(wěn)定運行。

電流互感器的工作原理基于電磁感應定律。它由閉合的鐵心和繞組組成，一次側(cè)繞組匝數(shù)較少，經(jīng)常有線路的全部電流流過。二次側(cè)繞組匝數(shù)較多，串接在測量儀表和保護回路中。當一次側(cè)有大電流流過時，根據(jù)電磁感應原理，二次側(cè)會產(chǎn)生一個較小的電流，這個電流與一次側(cè)電流成正比，比例系數(shù)由電流互感器的匝數(shù)比決定。

電流互感器在運行時，其二次側(cè)回路始終是閉合的，這樣測量儀表和保護回路的串聯(lián)線圈的阻抗就很小，電流互感器的工作狀態(tài)接近短路。需要注意的是，電流互感器的二次側(cè)嚴禁開路，因為開路會導致電流互感器產(chǎn)生高電壓，可能損壞設備并危及人員安全。

電流互感器廣泛應用于電力系統(tǒng)、工業(yè)自動化等領(lǐng)域，用于測量和保護。在電力系統(tǒng)中，AD02可以用于測量電流、功率、電能等參數(shù)，也可以用于實現(xiàn)過流保護、接地保護等功能。在工業(yè)自動化中，電流互感器可以用于監(jiān)測和控制各種電氣設備的運行狀態(tài)。

總的來說，電流互感器是一種重要的電氣設備，AD02利用電磁感應原理將高電流轉(zhuǎn)換成低電流，以便于進行測量和保護。在使用時，需要注意其二次側(cè)嚴禁開路，并需要根據(jù)實際需要選擇合適的型號和規(guī)格。

AD02 ABB 主要作用是將高電流轉(zhuǎn)換成低電流

Current transformer is a special electrical equipment, the main role of AD02 is to convert high current into low current, in order to facilitate measurement or protection. In this way, the situation of high current can be known by measuring low current without direct contact with high current, thus ensuring the safety of personnel and the stable operation of equipment.

The working principle of current transformers is based on the law of electromagnetic induction. It consists of a closed core and winding, the number of turns on the primary side winding is less, and the entire current of the line often flows through. The secondary winding has many turns and is connected in series in the measuring instrument and protection loop. When the primary side has a large current flowing, according to the principle of electromagnetic induction, the secondary side will generate a small current, which is proportional to the primary side current, and the proportional coefficient is determined by the turn ratio of the current transformer.

When the current transformer is running, the secondary loop is always closed, so that the impedance of the series coil of the measuring instrument and the protection loop is very small, and the working state of the current transformer is close to short circuit. It should be noted that the secondary side of the current transformer is strictly forbidden to open the circuit, because open circuit will cause the current transformer to produce high voltage, which may damage the equipment and endanger the safety of personnel.

Current transformers are widely used in power systems, industrial automation and other fields for measurement and protection. In the power system, AD02 can be used to measure current, power, electric energy and other parameters, and can also be used to achieve overcurrent protection, ground protection and other functions. In industrial automation, current transformers can be used to monitor and control the operating status of various electrical equipment.

In general, the current transformer is an important electrical equipment, AD02 uses the principle of electromagnetic induction to convert high current into low current, in order to facilitate measurement and protection. In use, it is necessary to pay attention to the second side is strictly prohibited to open the road, and it is necessary to choose the appropriate model and specification according to actual needs.
