5.2产品选用方法Product choice method
金属波纹式储油柜的规格主要依据变压器的总油重和使用地区最低环境温度确定。
当产品使用地区最低环境温度为-20℃及以上时，可在样本附录 “系列产品参数表”中直接选用，选用的储油柜适用变压器总油重必须大于已确定的变压器总油重。
如一台总油重为18吨的带开关储油柜的变压器，使用地区最低环境温度-20℃，在附录 “系列产品参数表”中选用适用变压器总油重为18.47吨的储油柜，其型号为：BP—Wb—980×3300 K。
当产品使用地区最低环境温度低于-20℃，需另行设计，调整补偿量。
The specification of the metal bellows sealed type of transformer oil conservator is determined mainly depending on the total oil weight of the transformer and the lowest environment temperature in the using area.
When the lowest environment temperature in the using area is -20℃ or above, you can directly choose it from “the series product parameter table” of sample and the total oil weight of the chosen conservator being suitable for the transformer mush be larger than total oil weight of the determined transformer.
If one set of transformer with switch conservator in 18 tons of total oil weight and the lowest environment temperature in the using area is -20℃, you can choose a conservator for the transformer in 18.47 tons of the total oil weight from “the series product parameter table”, its model is BP-Wb-980×3300K.
When the lowest environment temperature in the using area is below -20℃, it will need to a special design to adjust the compensation amount.

The oil level indicator adjustment after inject oil
After the conservator is injected full, if the oil level indicator difference during the transformer maintenance or running is too big i.e. over ±5℃, it is necessary to carry out the oil level indicator adjustment. The adjustment method is follow:
●The oil level is too high
○ Close the butterfly valve on the pipeline to transformer;
○ Open the valve on the discharging gas pipe and inject gas to increase pressure from the respiratory tube slowly and the oil flow out from the discharging gas pipe slowly. When the oil level indicator reaches at the predetermined oil level, quick close the valve on the discharging gas pipe and stop inject gas and the adjustment is finished.
●The oil level is too low
○ Close the butterfly valve on the pipeline to transformer;
○ Open the valve on the respiratory tube and close the valve on the discharging gas pipe. Inject oil into the conservator from injecting & discharging oil pipe. When the oil level indicator reaches at the predetermined oil level, close the valve on the injecting & discharging gas pipe quickly.
Note: Under have oil state, do not discharge oil directly from the injecting & discharging oil hole, because
discharge oil directly from the injecting & discharging oil hole will produce a false oil level.
8.6 真空注油
●打开排气口阀，从呼吸口抽真空至变压器所需真空度，关闭呼吸口阀门(此时磁翻转油位计上部压合区磁翻柱也全显橙色)；见图八
●对储油柜油腔及变压器本体抽真空，在此过程中，应严密监视磁翻转油位计橙色区。如显白，应检查呼吸腔是否有泄漏现象，如整个磁翻转油位计显白过半，应立即停止真空注油。否则由于呼吸腔不保真空，继续抽真空将损坏波纹芯体。
●按稍高于环境温度对应的注油量真空注油；见图九
●排气口阀打开，从呼吸口充气（小于0.02MPa)，至排气口稳定出油，且油位显示稍低于环境温度，关闭排气口阀。
见图十
Vacuum Oil-filling
● Open the exhaust pipe valve, vacuum from the mouth of respiratory pipe to the required vacuum degree, close the respiratory pipe valve (in this case the whole pressing zone of the magnet turnover oil level indicator display orange); See the figure 8
●Vacuum the oil chamber of conservator and the transformer, in this process should be closely monitored the orange zone of the magnet turnover oil level indicator. As was white, should check whether there is leakage in respiratory chamber, if the magnetic flip of the oil level indicator was half white, you should immediately stop the vacuum. Otherwise, vacuum will damage the corrugated core body as the respiratory chamber can not maintain the vacuum.
●Oil-filling to the volume slightly higher than that the ambient temperature required from oil-filling pipe or transformer. See the figure 9
● Open exhaust valve, gas
