1. 전압비

두 그룹의 수를 설정합니다. low-frequency 변신 로봇 N1 및 N2로 코일, N1은 1차 권선, N2는 2차 권선입니다.
1차 권선에 교류 전압을 인가하면 2차 코일 양단에 유도 기전력이 발생한다.
When N2>N1, its induced electromotive force is higher than the primary voltage added, this low-frequency 변신 로봇 is called boost low-frequency 변신 로봇.

효율성 2.

At rated power, the ratio of the output power to the input power of the low-frequency 변신 로봇 is called the efficiency of the low-frequency 변신 로봇, that is, η=P2/P1×100%.
Where η is the efficiency of the low-frequency 변신 로봇, P1 is the input power and P2 is the output power.
When the output power P2 of the low-frequency 변신 로봇 is equal to the input power P1, the efficiency η is equal to 100%, at this time the low-frequency 변신 로봇 will not produce any loss, but in fact this low-frequency 변신 로봇 does not exist, low-frequency 변신 로봇 transmission power always produce loss, this loss mainly copper loss and iron loss.
The efficiency of the low-frequency 변신 로봇 is closely related to the power level of the low-frequency 변신 로봇. Usually, the greater the power, the smaller the loss and the higher the efficiency.
반대로, 전력이 낮을수록 효율이 낮아집니다.

3. 작동 주파수

Because the low frequency 변신 로봇 core loss and frequency is very important, it should be designed and used according to the frequency of use, this frequency is called the working frequency.

4. 정격 전압

This parameter refers to the voltage allowed to be applied on the primary winding of the low-frequency 변신 로봇. The voltage applied on the primary winding of the low-frequency 변신 로봇 shall not be greater than the specified value in normal operation.

5. 정격 전력

Rated power refers to the low frequency 변신 로봇 in the specified frequency and voltage, can work for a long time, and does not exceed the specified temperature rise of the secondary output power.
The unit of rated power of low-frequency 변신 로봇 is VA(volt ampere), instead of W(watt). This is because there will be part of reactive power in the rated power, so it is more accurate to express VA.

6. 무부하 전류

When the low-frequency 변신 로봇 secondary winding open, there is still a certain current in the primary coil, this current is called no-load current.
무부하 전류는 자화전류(자속발생)와 철손전류(철손전류)로 구성되어 있습니다.
를 위해 low-frequency 변신 로봇 with 50Hz power supply, 무부하 전류는 기본적으로 자화 전류와 같습니다.

7. 부하 손실 없음

When the low-frequency 변신 로봇 is open in the secondary, the power loss measured in the primary is the no-load loss.

8. 절연 저항

This parameter represents the insulation performance between each coil of the low-frequency 변신 로봇 and between each coil and the iron core.
절연 저항은 사용된 절연 재료의 성능, 온도 및 습도와 관련이 있습니다.
Insulation resistance is a parameter that represents the insulation performance of low-frequency 변신 로봇. It is the ratio of voltage and leakage current applied on the insulation layer, including the insulation resistance value between windings, windings and core and shell.
절연 저항이 매우 크기 때문에 일반적으로 메그옴 미터(또는 멀티미터 R×10kΩ 블록)만 사용하여 저항을 측정할 수 있습니다.
If the insulation resistance of the low-frequency 변신 로봇 is too low, the case may be charged in use and even the low-frequency 변신 로봇 winding may be broken down and burned.

9. 온도 상승
When the low-frequency 변신 로봇 is put into operation, the part where the coil temperature is higher than the ambient temperature is called the coil temperature rise.
작동 온도가 주변 온도를 초과하는 코어 부분을 코어 온도 상승이라고 합니다.
온도 상승에는 가장 뜨거운 온도 상승과 평균 온도 상승의 두 가지 종류가 있습니다.
Generally, the average temperature rise of the coil is taken as the temperature rise index of the low-frequency 변신 로봇.
Temperature rise is an important factor affecting the life of low-frequency 변신 로봇.
The allowable temperature rise of a low-frequency 변신 로봇 is determined by its insulation and heat resistance class.
