矿用变压器与矿用蓄能器串联使用的特点

矿用变压器与矿用蓄能器串联使用的特点及优化条件矿用设备中有许多能量回收的工况,例如矿用抽油机的下冲,阶段液报电梯的下降阶段矿用驱动车辆的制动阶段等都在着负值负载向动力系统回馈能量的工况。理论研究明,进行能量回收的矿用蓄能器与可调式矿用变压器串联使用。能以最优化的方式利用矿用落能器的存储能力。这是因为矿用蓄能器前端有了压力调节器后,其初始工作灰力及储能时最高作压力都可以不受系统的限制。
Mine and mine transformer energy storage has a lot of energy recovery operation and optimization of mining equipment is used in series, such as mine pumping down, lift down stage liquid phase at mine driving vehicle braking stage are in a negative feedback load energy to the power system operating conditions. The theoretical research shows that the energy accumulator of the energy recovery can be used in tandem with the adjustable mining transformer. The storage capacity of the mine energy accumulator can be optimized. This is because the front of the accumulator has a pressure regulator, and the initial work, the ash force and the energy storage can be maximum pressure, and the system can be free from the restriction of the system.
山东变压器厂家http://www.jnwdsh.com公司成功通过了ISO14000环境管理体系国际认证,为企业开拓国际市场准备了一张“绿色名片”。过线槽为铜线的拐线路径,同时为避免生产中出现破损、插针裂脚、夹砂等异常情况,所以过线槽的宽度需终合考虑:铜线的直径、针孔边缘壁厚、毛边处理砂粒大小。一般情况下,过线槽适合做大,这样可以避免夹砂,也方便客户过铜线,但过线槽做大后,剩余的针孔边缘壁厚便会偏小,插针生产时容易出现裂脚。
The company has successfully passed the international certification of ISO14000 environmental management system, and has prepared a green business card for enterprises to explore the international market". A slot for turn line path of the wire at the same time to avoid the production of damage, crack pin foot, sand and other anomalies, so the line width of the groove end to consider: the size of pinhole diameter, wall thickness, edge burr processing copper sand. In general, the cross line groove is suitable for bigger, so as to avoid sand clamping, and also convenient for customers to cross the copper wire, but after the line groove is bigger, the remaining pinhole edge wall thickness will be too small, and the pin production is easy to break feet.
变压器运行中的检查
山东变压器厂家
Inspection of transformer operation
(1)检查变压器上层油温是否超过允许范围。由于每台变压器负荷大小、冷却条件及季节不同,运行中的变压器不能以上层油温不超过允许值为依据,还应根据以往运行经验及在上述情况下与上次的油温比较。如油温突然增高,则应检查冷却装置是否正常,油循环是否破坏等,来判断变压器内部是否有故障。
(1) check whether the upper oil temperature exceeds the allowable range. Because each transformer load, cooling conditions and different seasons, can not run in the transformer top oil temperature does not exceed the allowable value as the basis, should also be based on past experience and operation in the above case and the last oil is relatively. If the oil temperature suddenly increases, it should check whether the cooling device is normal, whether the oil circulation is damaged and so on, to determine whether there is a fault in the transformer.
(2)检查油质,应为透明、微带黄色,由此可判断油质的好坏。油面应符合周围温度的标准线,如油面过低应检查变压器是否漏油等。油面过高应检查冷却装置的使用情况,是否有内部故障。
(2) check the oil quality, should be transparent, microstrip yellow, which can determine the quality of oil. The oil level shall be in line with the ambient temperature. If the oil level is too low, the transformer should be checked for leaks. If the oil level is too high, check the use of the cooling device and see if there is an internal fault.
(3)变压器的声音应正常。正常运行时一般有均匀的嗡嗡电磁声。如声音有所改变,应细心检查,并迅速汇报点检员,是否检修处理。
(3) the sound of the transformer should be normal. There is a normal buzzing sound when running normally. If the sound has changed, should be carefully examined and promptly reported to the inspectors, whether the maintenance process.
(4)应检查套管是否清洁,有无裂纹和放电痕迹,冷却装置应正常。工作、备用电源及油泵应符合运行要求等等。
(4) the casing shall be checked for cleanliness, cracks and discharge traces, and the cooling device shall be in normal condition. Work, standby power and oil pump should meet the operation requirements and so on.
