Operation and maintenance management of oil immersed transformer
Shtep.Many people probably don't know much about the power distribution transformer manufacturers. In fact, the transformer can be plugged in for trial operation after careful inspection before capital investment. During the trial operation period, you must pay attention to the following points. Whether there is abnormal sound noise and vibration, whether there is abnormal smell such as coke smell, and whether there is discoloration caused by partial overheating. Ventilation is good. In addition, we should also pay attention to the following aspects.
The no-load impulse closing working voltage shall not exceed 5% of the working voltage marked on the gear of the transformer,ShtepThree phase transformer 100kW, the delay time after power receiving shall not be less than 10min, and the time interval of each closing shall not be less than 5min.
.Different diversion methods, dry-type transformers mostly use silica gel waterproof casing, while oil transformers mostly use porcelain waterproof casing;
The input and output three-phase power lines shall be connected to phase a, phase B and phase C respectively according to the color of yellow, green and red bus duct of transformer terminal board. The zero line shall be connected to the neutral zero line of transformer voltage, and the grounding wire, transformer casing and its transformer point shall be connected to each other. At ordinary times, the ground wire and zero wire are led out by the neutral wire of the transformer. (for example, the transformer box shall be matched with the ground wire mark of the shell and connected with each other). Check the input and output lines to ensure they are appropriate and accurate.

Performance parameters of key work clothes,ShtepOil immersed regulator manufacturer, machinery and equipment of each process flow; The natural working environment is basically regulated.
When oil samples are used, the safety and fire safety technical specifications on the spot shall be strictly implemented.
The transformer manufacturer will introduce the efficiency of the transformer to you
Noise solution of dry-type transformer
Executive standard.The oil in the machinery and equipment of the oil storage tank shall generally stand for more than 8h before sampling; it is not necessary to stand when sampling on the running power transformer.
Noise solution of dry-type transformer
A zero line of the power transformer is connected with the working equipment. Since the voltage formed by the server during operation will be sent to the power transformer along with the cable, the power transformer will be transported and sent to the power consuming machines and equipment. What is the zero line of the actual power transformer? Let's introduce it to us.

Performance parameters of key work clothes, machinery and equipment of each process flow; The natural working environment is basically regulated.
Recommendation and consultation.Note: in the whole process of safety patrol inspection, the on-site operation and maintenance management staff must use temperature tester or thermal imager to carry out purposeful inspection on the transformer itself, terminal block and other accessories; The sound during the operation of the transformer is a symmetrical current sound. If the sound is found to be abnormal significantly expanded, or there is local sound, the cause shall be found immediately and certain effective measures shall be taken. If necessary, the load can be reduced or the operation of the transformer can be stopped.
Power transformer is indispensable for power stations and substations, but we must pay attention to many problems in the whole process of applying power transformer.
It will also produce many faults, effectively deal with various faults of oil immersed transformer, make full use of the performance indicators and advantages of oil immersed transformer, and continuously improve the safety factor of oil immersed transformer. Ignition is a common fault of oil immersed transformer. The key fault of oil immersed transformer is short-circuit fault, and short-circuit fault is more general.
Shtep.When the new oil filled by the power transformer and the oil sample that has just been considered are used, and apply sound insulation window, silencing cylinder, floating concrete floor damping pad and other sound insulation and noise reduction commodities to achieve sound insulation effect.
