Storage Conditions

1. Temperature: Transformers should be stored indoors in a dry, ventilated, and corrosion-free environment with a relative humidity of no more than 85% and a surrounding medium temperature of no more than +40 ℃ and no less than -25 ℃. This helps to prevent the transformer from being damp, moldy, or damaged by other environmental factors.

2. Humidity: High humidity may cause corrosion and damage to the internal components of the transformer. Therefore, it should be ensured that the humidity of the storage environment is within the allowable range.

3. Avoid mechanical shock: Transformers should avoid strong mechanical shock and vibration during storage and transportation. This may cause looseness or damage to the internal components of the transformer.

4. Avoid direct sunlight: Long periods of direct sunlight may cause the temperature of the transformer to rise, accelerating the aging process. Therefore, it should be ensured that the transformer is stored in a place away from direct sunlight.

5. Fire and explosion prevention: The transformer should be stored in an environment free of flammable and explosive materials to prevent damage to the transformer caused by fire or explosion.

FAQ

Q1

What is the main function of a dry type 6kV 10kV AC circuit current transformer?

Re:The main function of a dry type 6kV 10kV AC circuit current transformer is to achieve the conversion of high current to low current. In the power system, the current often reaches a very high level, and directly measuring these high currents is neither safe nor practical. Therefore, current transformers, through their special design, can sense high currents and generate a low current signal proportional to it. This low current signal can be safely and accurately captured and recorded by measuring equipment. This conversion function enables staff to conveniently monitor the operating status of the power system, thereby achieving effective protection and control of the power system.

Q2

Why does the dry type 6kV 10kV current transformer adopt an epoxy resin cast fully enclosed structure?

Re:The dry type 6kV 10kV current transformer adopts an epoxy resin casting fully enclosed structure, mainly for the consideration of its working environment. Epoxy resin has good insulation performance and mechanical strength, which can effectively resist damage to the internal components of transformers caused by dust, moisture, and external impacts. In addition, the fully enclosed design can also improve the heat dissipation performance of the transformer, ensuring its long-term stable operation. This structure not only enhances the reliability of the transformer, but also reduces maintenance costs and extends its service life.

Q3

What is the impact of this fully enclosed design on the operational performance of dry-type 6kV and 10kV current transformers?

Re:The fully enclosed design has a positive impact on the working performance of dry type 6kV 10kV current transformers. Firstly, it improves the insulation performance of the transformer and effectively prevents the occurrence of electrical faults. Secondly, the fully enclosed structure enhances the mechanical strength of the transformer, enabling it to withstand external shocks and vibrations, thereby ensuring the stability and accuracy of measurement. In addition, the fully enclosed design also optimizes heat dissipation performance, reducing the risk of performance degradation or damage to transformers caused by overheating.

Q4

What are the advantages and limitations of dry type 6kV 10kV current transformers compared to open type current transformers?

Re:Compared to open type current transformers, dry type 6kV 10kV current transformers have the following advantages: firstly, their fully enclosed design improves the insulation performance and mechanical strength of the transformer, enhancing safety and reliability; Secondly, dry type transformers have better heat dissipation performance, which can reduce problems caused by overheating; Finally, dry type transformers are easier to install and maintain, reducing operational costs. However, dry type transformers also have some limitations, such as their relatively high cost and may not be as flexible as open type transformers in certain specific application scenarios.

Q5

How to ensure the measurement accuracy and precision of dry type 6kV 10kV current transformers?

Re:Ensuring the measurement accuracy and precision of dry-type 6kV and 10kV current transformers is crucial. Firstly, during production, transformers need to undergo strict quality control and calibration to guarantee that their performance meets standard requirements. Secondly, correct installation steps and wiring methods should be followed during installation to reduce errors and interference. In addition, regular maintenance and inspection of transformers are also essential, including cleaning surfaces, inspecting connecting wires and fasteners, etc. Through these measures, the measurement accuracy and precision of dry type 6kV 10kV current transformers can be maximized.
