配电变压器使用中应注意的几个问题

Several problems should be paid attention to when using distribution transformer:
1、 在选择配电变压器时,除充分考虑其性能外,容量的选择要恰当,要充分考虑负荷的大小,确保负荷利用率;容量选择太大,除购买的价格高,一次性投资大外,在运行过程中,固有的空载损耗也大。容量选择太小,除不能满足用电的要求外,负载损耗也往往偏高。
1, in the selection of distribution transformer, in addition to the performance of the full consideration, the capacity to choose appropriate, to fully consider the size of the load, ensure the load utilization rate; capacity is too large, in addition to the purchase price is high, one-time investment is large, in the operation process, the no-load loss is inherent. Capacity selection is too small, in addition to the power consumption can not meet the requirements, the load loss is often high.
2、山东变压器厂http://www.jnwdsh.com合理的确定采用的台数,这一般从安全性和经济性两个方面考虑;有大量一级负荷或虽为二级负荷但从保安角度需设置,在负荷波动大且间隔的时间长,可考虑选择一大一小的多台组合;供电可靠性要求高时应考虑备用变压器,当然这里还有场地等各个方面因素的影响。当动力和照明共用一台变压器,严重影响灯泡寿命或照明质量,应设专用照明变压器。
Number 2, to determine the reasonable use, it is generally considered from the two aspects of safety and economy; a large number of a load or is two load but from the security perspective is needed, the load fluctuation and the interval of time is long, can be considered a small multiple of power supply; high reliability requirements should be considered in the standby transformer, of course there are various influence factors such as the site. When power and lighting share a transformer, which seriously affects the life of the bulb or the quality of the lighting, a special lighting transformer shall be set up.
(1)变压器基础不牢固或不平整(一个角悬空),或者底板太薄。 (2)用槽钢把变压器架起来,会增加噪音。
(1) the foundation of the transformer is not firm or uneven (one angle is left vacant), or the bottom plate is too thin. (2) use the channel steel to support the transformer, it will increase the noise.

解决方法:
Resolvent:
(1)由安装单位对原安装方式进行改造。
(1) the installation method is modified by the installation unit.
(2)电力变压器小车下面加防震胶垫,可解决部分噪音。
(2) shockproof rubber pad under the trolley of power transformer can solve part of the noise.
安装环境的影响
The impact of the installation environment
原因:运行环境影响变压器的噪音,环境不利使变压器噪音增大3dB~7dB。
Reason: the operating environment affects the noise of transformer, the environment is disadvantageous, the transformer noise increases 3dB ~ 7dB.

(1)变压器室很大又很空旷,没有其他设备,有回音。
(1) the transformer room is large and spacious, and there is no other equipment, there is an echo.
(2)变压器离墙太近,不到1米。变压器放在拐角处,墙面反射噪音与变压ha
(2) the transformer is too close to the wall, less than 1 meters. The transformer is placed on the corner and the wall reflects noise and variable pressure ha
器噪音叠加,使噪音增大。
The noise is superimposed so that the noise increases.
(3)原先使用油变,换干变以后会影响变压器的噪音。原因是,原油变室
(3) the original use of oil changes, dry change will affect the noise of the transformer. The reason is that the crude oil change chamber
比较狭小,又有一个漏油室和一个漏油孔,变压器就像放在一个音箱上。
Relatively small, there is an oil leak chamber and an oil leak, the transformer is like on a speaker.
