压器低损耗、低噪音的效果是如何体现的?

随着技术的不断发展,变压器行业也发展的越来越好了。那么,和传统的电力变压器、电炉变压器相比,我们的产品经过不断的创新,达到了低损耗、低噪音、抗短路能力强的效果。
With the continuous development of technology, the transformer industry is also developing better and better. Then, compared with the traditional power transformer and electric furnace transformer, our product has been continuously innovating, which achieves the effects of low loss, low noise and short circuit resistance.
济南变压器维修http://www.jnwdsh.com其实干式变压器的安全运行和使用寿命,很大程度上取决于变压器绕组绝缘的安全可靠。绕组温度超过绝缘耐受温度使绝缘破坏,是导致变压器不能正常工作的主要原因之一,因此对变压器的运行温度的监测及其报警控制是十分重要的,今对TTC-300系列温控系统作一简介。
In fact, the safe operation and service life of dry-type transformers largely depend on the safety and reliability of transformer winding insulation. Winding temperature exceeds the temperature of the insulation damage to insulation resistance, is one of the main causes of transformer can not work normally, so the transformer operating temperature monitoring and alarm control is very important, this temperature control system of TTC-300 series are introduced.
(1)风机自动控制:通过预埋在低压绕组最热处的Pt100热敏测温电阻测取温度信号。变压器负荷增大,运行温度上升,当绕组温度达110℃时,系统自动启动风机冷却;当绕组温度低至90℃时,系统自动停止风机。
(1) fan automatic control: the temperature signal is measured by the Pt100 thermistor, which is embedded in the hottest part of the low voltage winding. When the winding temperature is up to 110 DEG C, the system will automatically start the fan cooling. When the winding temperature is low to 90 degrees, the system will automatically stop the fan.
(2)超温报警、跳闸:通过预埋在低压绕组中的PTC非线性热敏测温电阻采集绕组或铁心温度信号。当变压器绕组温度继续升高,若达到155℃时,系统输出超温报警信号;若温度继续上升达170℃,变压器已不能继续运行,须向二次保护回路输送超温跳闸信号,应使变压器迅速跳闸。

(2) over temperature alarm and trip: the coil or core temperature signal is collected by the PTC nonlinear thermal temperature measuring resistor embedded in the low voltage winding. When the transformer winding temperature continues to rise, if reached 155 degrees, the output of the system over temperature alarm signal; if the temperature continues to rise up to 170 degrees Celsius, the transformer cannot continue to be delivered over temperature tripping signal to the two circuit, the transformer should quickly tripping..
(3)温度显示系统:通过预埋在低压绕组中的Pt100热敏电阻测取温度变化值,直接显示各相绕组温度(三相巡检及最大值显示,并可记录历史最高温度),可将最高温度以4~20mA模拟量输出,若需传输至远方(距离可达1200m)计算机,可加配计算机接口,1只变送器,最多可同时监测31台变压器。
(3) Pt100 thermistor temperature display system: the low-voltage windings embedded in the measured temperature value, directly showing the winding temperature (maximum three-phase inspection and display, and recorded its highest temperature), the highest temperature in 4 ~ 20mA analog output, for transmission to the distant (a distance of up to 1200m) computer, can be equipped with computer interface, 1 transmitter can simultaneously monitor up to 31 transformers.
在使用干式变压器的时候,有时合闸过程中出现合不上,那要如何解决呢? 解决方案:干式变压器每次合闸过程中都需要解除保护才能合上。干式变压器的干式是对应油浸式变压器而出现的称呼。适用于非液态绝缘的变压器。
In the use of dry-type transformers, sometimes closing process does not appear, and how to solve it? Solution: dry transformer, each closing process, need to be lifted to close. Dry-type transformer dry-type is the corresponding oil immersed transformer and called. A transformer suitable for non liquid insulation.
合闸之前需要解除保护应该是变压器上的保护器的原因。部分电子式保护器在未通电状态内部的接点与通电后初始状态的接点状态是相反的。
The protection should be removed before switching on. It should be the protector of the transformer. In some electronic protectors, the contact state between the contacts in the non energized state and the initial state after the energization is reversed.
