龙岩变压器的优点和缺点
龙岩变压器的优点
       1)经济效益高，龙岩变压器不需要维护，不需要吊心，节约了大量的吊心，维护费用(包括人力、物力、资金)保养工作量大大减少，与传统龙岩变压器相比，无需绝缘液体的取样和试验.无需对液体可能需要进行的补充、过滤和更换.无需清洗呼吸玻璃，无需监视储油柜油面。
       2)由于冷却介质和周围空气不接触，使液体和绝缘材料不会吸收任何水分，从而不会降低绝缘强度。由于氧气无法进入油箱，从而避免了绝缘材料被氧化的老化过程。油与空气不接触，不会给环境带来污染.
 
龙岩变压器的缺点
       1)龙岩变压器油体积变化的胀缩部件价格较高(波纹片或膨胀式散热器)，特别是其生产设备如波纹油箱生产线价格高.使龙岩变压器成本较高，产品价格较贵。波纹油箱的波纹片和膨胀式散热器的胀缩片因具有弹性，不可能将壁厚做得很厚。这样万一渗油，焊补比较困难。
       2)龙岩变压器有的有油位指示器；有的没有油位指示器，必须用探杆才能测知油位，这样不便于监视油位和油色。
 
All the advantages and disadvantages of sealed transformer
     1) economic efficiency, sealed transformers require no maintenance, no hanging heart, saving a lot of hanging heart, maintenance costs (including human, material, money) greatly reduce the maintenance workload, compared with traditional transformers, without insulating liquid sampling and testing. no need to add the liquid that might be required, and replacement filters. breathe without cleaning the glass, without the need to monitor oil storage cabinet.
     2) Due to the cooling medium and the surrounding air does not contact the liquid and the insulating material will not absorb any moisture, so as not to reduce the dielectric strength. Because oxygen can not enter the tank, thus avoiding the insulating material is oxidized to the aging process. Oil and air does not contact, no pollution to the environment.
 
 The disadvantage of sealed transformer
     1) sealed transformer oil volume change of the expansion and contraction components of higher prices (corrugated sheet or expansion-type radiator), especially its production of corrugated tank production line equipment such as high price. So that the entire sealed transformer high cost products more expensive. Corrugated sheet corrugated tank-type heat sink and expansion due to flexible film expansion and contraction, it is impossible to do a very thick wall. This case oil leakage, welding more difficult.
 2) There are some sealed transformer oil level indicator; there is no oil level indicator, must probe to detect the oil level, this is not easy to monitor the oil level and oil color.
