茂名市以变压器回收价收购电力变压器。变压器按用途可分为电力变压器、试验变压器、仪表变压器和专用变压器:电力变压器是电力用户输配电和配电的必备设备；试验变压器用于测试电气设备的耐压(升压电压)；互感器用于配电系统的电气测量和继电保护(PT、CT)；专用变压器包括冶炼用电炉变压器、焊接变压器、电解用整流变压器、小型调压变压器等。电力变压器常用的冷却方式一般分为三种:油浸自冷、 oil-immersed air-cooling and forced oil circulation. Oil-immersed self-cooling: it is to bring heat to the tank wall and radiator pipe by natural convection of oil, and then dissipate heat by convection conduction of air. It has no special cooling equipment. Oil-immersed air-cooled type: On the basis of oil-immersed self-cooling, a fan is installed on the fuel tank wall or radiator pipe, and a blower is used to help cool. After installing air cooling, the capacity of transformer can be increased by 30%~35%. Forced oil circulation cooling methods can be divided into strong oil air cooling and strong oil-water cooling. The oil in the transformer is pumped into the oil cooler by an oil pump and then returned to the oil tank. The oil cooler is made into a special shape that is easy to dissipate heat. The medium is cooled by fan blowing or circulating water, 热量被带走。变压器是一种用于转换交流电压和电流并传输交流电能的静态电气设备。
变压器回收价格下图为MF47万用表。MF47万用表外观如下图所示，由手柄、表头、测量选择开关、欧姆档调零旋钮、唱针插座、晶体管插座等组成。万用表面板上部是微安表头，表头下部中间有一个机械调零器，用来校准指针的机械零位。如下图所示。指针下方的表盘上有六条刻度线，从上到下分别是电阻刻度线、电压电流刻度线、晶体管数值刻度线、电容刻度线、电感刻度线和电平刻度线。表盘还配有反光板，消除视差。在面板下部的中间是一个测量选择开关，你可以通过旋转一个旋钮来选择每个档位。
The most basic type of transformer consists of two groups of coils wound with wires, and they are combined with each other in an inductive way. When an AC current (with a known frequency) flows in one set of coils, an AC voltage with the same frequency will be induced in the other set of coils, and the induced voltage depends on the degree of coupling and magnetic cross-linking between the two coils.
When purchasing power transformers, transformer recycling can be divided into: distribution transformers, power transformers, fully sealed transformers, combined transformers, dry-type transformers, oil-immersed transformers, single-phase transformers, electric furnace transformers, rectifier transformers, etc.
